PRESS RELEASE Cabinet Science Policy & City of Ghent, 31 January 2021
The city of Ghent will be the godfather city of the new Belgian research vessel Belgica. The ship will be baptised in Ghent in September 2021. This was announced on 31 January 2021 by the State Secretary for Science Policy, Thomas Dermine, and the Mayor of Ghent, Mathias De Clercq.
The city of Ghent will be the godfather of the new research vessel. The State Secretary for Science Policy, Thomas Dermine, took this decision after consultation with the Mayor of Ghent Mathias De Clercq. The city of Ghent had already expressed its interest in becoming the godfather of the advanced research vessel. A candidacy supported by the University of Ghent, an important scientific partner of the Belgica.
“At the moment, the finishing touches are being put to the vessel in Vigo, Spain, which is also undergoing extensive testing. In September 2021, Belgium’s pride in marine research and technology will be christened in Ghent,” jubilates State Secretary for Science Policy Thomas Dermine. “With the Belgica, we are helping our country to become one of the world leaders in marine and underwater exploration. I am very happy with Ghent’s enthusiasm to become the godfather city of this exceptional ship”, continues Thomas Dermine.
“We are particularly honoured and proud to be the godfather city of the new research vessel Belgica”, says Mayor Mathias De Clercq enthusiastically. “Ghent will use this title to stimulate young people’s and schools’ interest in science and to make the most of Ghent’s assets as a knowledge and port city. The ship is powered by Ghent engines and the people of Ghent will proudly welcome the Belgica”, Mathias De Clercq continues.
The new Belgica, a 71-metre oceanographic research vessel, will play a key role in Belgian and European marine research in the coming decades.
Starting in autumn 2021, the ship will embark on expeditions to research numerous issues, such as the fight against global warming and better protection of the environment.
As a multidisciplinary research vessel, the Belgica will support scientific research in the fields of fisheries, biology, geology, climate and chemistry.
The Belgian State, represented by the Federal Science Policy Office (BELSPO), is the owner of the ship. The Royal Belgian Institute of Natural Sciences (RBINS) will manage the vessel in cooperation with the Ministry of Defence and a private operator.
The new research vessel will succeed the current research vessel Belgica (launched in 1984), which in the past 36 years has travelled almost one million kilometres and facilitated more than 1,000 scientific expeditions.
Like its predecessor, the Belgica will operate within the European EUROFLEETS network, which gives European researchers access to a common marine research infrastructure.
The new ship will be baptised in September in Ghent after an inauguration trip between Zeebrugge and Ghent in the presence of Princess Elisabeth. As a reminder, the Duchess of Brabant is the godmother of the new Belgica.
Activities for the general public will be organised in the margins of this official inauguration.
Agentschap voor Maritieme Dienstverlening en Kust, afdeling Kust, van C.B.R. Cementbedrijven nv – Afdeling SAGREX en De Hoop Bouwgrondstoffen bv c.o. SATIC nv have applied for the prolongation and/or extension of their concession for sand and gravel extraction in the Belgian part of the North Sea. These applications are subject to an environmental impact assessment procedure.
The applications and the environmental impact assessment report, including a design of appropriate assessment, can be downloaded below (in Dutch). Objections received shall be added after the public consultation.
While Belgium emerged as a world leader in the offshore wind industry, the Belgian scientists that monitor the environmental impact of offshore wind farms have also developed extensive knowledge and expertise. Shortly after the first Belgian offshore wind zone was completed (the world’s biggest to be operational), the monitoring consortium presents its latest conclusions and recommendations in a new report. Different components of the marine ecosystem are impacted in different ways. Therefore, the environmental impact is not a black or white story. Balancing the energy and biodiversity crises was never expected to be an easy task. The monitoring continues, as does the development of mitigation measures where needed.
The European Commission imposes targets for the contribution of renewable energy sources to the total electricity production by all Member States (Directive 2009/28/EC). For Belgium, 13 % of the total energy consumption must be covered by renewable energy by 2020. Offshore wind farms in the Belgian part of the North Sea make an important contribution, and a first zone of 238 km² along the border with the Netherlands was reserved for wind farms to achieve this goal. At the end of 2020, after 12 years of construction, the wind farms in this zone were completed. A total of 399 turbines is now operational in eight wind farms, with an installed capacity of 2,26 Gigawatts (GW) and the production of an average of 8 TWh. This represents approximately 10 % of Belgium’s total electricity demand, or 50 % of the electricity needs of all Belgian households. At the moment, the construction works have ended, but a second area for renewable energy of 285 km² is foreseen in the new Marine Spatial Plan for the period 2020-2026, intending to add a minimum of 2 GW to the total Belgian offshore wind energy production capacity.
Balancing the energy and biodiversity crises
It is very challenging to find a balance between the installation of offshore wind farms as measures to combat the energy/climate crisis and acceptable environmental impacts in the light of combatting the biodiversity crisis. Both crises need to be tackled, but within conditions that do not worsen the other crisis. It also needs to be kept in mind that the Belgian offshore wind farms are not unique cases: on the scale of the southern North Sea, offshore wind farm areas are also foreseen in the adjacent Dutch Borssele zone (344 km²) and in the French Dunkerque zone (122 km²). Cumulative ecological impacts will hence continue to be a major concern in the years to come. Only by closely cooperating towards the common goal of increasing the production of renewable energy with acceptable ecological impacts, science, industry and policy can jointly address the challenge.
Permits and Monitoring
Before a wind farm can be installed in Belgian marine waters, developers must obtain a domain concession and an environmental permit. This permit imposes a scientific monitoring programme to assess the effects of the project on the marine ecosystem and includes terms and conditions that are intended to minimise and/or mitigate aspects of the impact that are evaluated to be unacceptable. The monitoring programme is carried out by the WinMon.BE consortium. Annual reports that target marine scientists, managers, policy makers and offshore wind farm developers are published in the ‘Memoirs of the Marine Environment’-series of the Royal Belgian Institute of Natural Sciences.
The monitoring programme covers a broad range of ecosystem components from soft sediment and (artificial) hard substrate invertebrates and fish to seabirds and marine mammals, as well as their interactions. In other words, the monitoring does not only focus on the quantification of the extent of the impacts on the marine ecosystem but also aims at revealing the cause-effect relationships of certain impacts.
Because the different studied ecosystem components are impacted by offshore renewable energy developments in different ways, and at different spatial and temporal scales, the environmental impact cannot be easily summarised as positive or negative. The main conclusions and recommendations of the latest studies include:
The use of double bubble curtains proved partially effective to reduce underwater sound associated with the installation of 8 m diameter monopiles to levels in line with national standards.
Following a review of compliance with relevant environmental license conditions, an optimization of the use of acoustic deterrent devices and noise mitigation measures, and formalizing marine mammal surveys, are recommended.
Over 80% of the estimated number of seabirds colliding with turbines in Belgian waters are large gulls. Wind farm location, layout and turbine size determine the expected number of collisions.
Future research should address specific aspects of the impact on individual birds and populations, and mitigation: correlation between displacement and wind farm characteristics, large gull movements and an empirically informed species-distribution model to support marine spatial planning.
Sediments become finer and organically enriched close to jacket foundations, accompanied by higher abundance and diversity of macrofauna. Typical coastal species from productive waters are colonizing the now finer sediments around the turbines.
Nine years after construction, the first signs become apparent that wind farms can act as refugia for fish that prefer soft sediments (e.g. plaice), probably resulting from fisheries exclusion and increased food availability, while the reef effect expands to soft sediments between the turbines (colonized by invertebrates of hard substrates).
Offshore wind farms influence the local food webs from the basis, with colonizing fauna reducing primary producers, to higher trophic levels, with several fish species intensively feeding on the colonizing fauna.
Future Monitoring
The fact that the first Belgian zone for offshore wind farms has been fully completed does not mean that the monitoring now comes at an end. Although the understanding of the effects of wind turbines on the marine environment and its inhabitants has grown significantly over the past 10 years, there is still much to learn about the longer-term environmental impact of offshore wind farms. To allow for that, the current cooperation model in which scientists and the offshore wind industry document the impact of the operational phase of the wind farms will continue to remain active. “Examples of fields that we have started to explore but cannot yet report on include the improvement of modelling of bird and bat collision risks, the monitoring of the impact of continuous underwater sound that is generated by operational turbines, and the longer-term effects on fish populations. It also remains unknown how fouling communities on the wind turbines will further evolve, and how the observed behavioral changes impact the individual fitness, reproductive success and survival of marine animals.” says Steven Degraer, coordinator of the WinMon consortium and head of the Marine Ecology and Management team of the Royal Belgian Institute of Natural Sciences. Degraer continues “Extending the cooperation will also allow to further evolve in the field of designing, testing and improving mitigation measures to directly manage unwanted effects on the marine ecosystem.”
Monitoring activities will also have to be initiated in the same way in the second Belgian offshore wind zone once the construction will start there. The collection of baseline data on the state of the marine ecosystem in that area, on which a future assessment of changes will rely, is already ongoing. In addition, rapidly evolving technology and construction practices require frequent reassessment of observed impacts.
In the meantime, the Belgian expertise on the monitoring of the environmental impact of offshore wind farms is also getting international attention. “Monitoring plans that are inspired by the Belgian work are being set up in both France and the United States, so Belgium should not only be considered a world leader in the offshore wind industry, but also in the monitoring of their environmental impact.” Degraer concludes.
The Monitoring Programme WinMon.BE is a cooperation between the Royal Belgian Institute of Natural Sciences (RBINS), the Research Institute Nature and Forest (INBO), the Research Institute for Agriculture, Fisheries and Food (ILVO) and the Marine Biology Research Group of Ghent University, and is coordinated by the Marine Ecology and Management team (MARECO) of the Royal Belgian Institute of Natural Sciences.
On Wednesday 13 January 2021, Deputy Prime Minister and Minister of North Sea Vincent Van Quickenborne checked to what extent ships in the Belgian part of the North Sea comply with the applicable air pollution standards. To this end, he flew along in the Belgian Coast Guard plane. Through the application of a ‘sniffer’ sensor in this aircraft, our country is known as a pioneer in the international fight against air pollution above the sea. The sensor allows polluting components in ship emissions to be measured in the field. Sulphur measurements have been on the programme since 2016, and since 2020 nitrogen compounds can also be detected. With this, Belgium was the first to be ready to monitor above the sea the restrictions on nitrogen emissions from ships that will apply in the North Sea from 1 January 2021.
Emissions of sulphur dioxides (SO2) and nitrogen oxides (NOx) from ships contribute significantly to various health and environmental problems, such as the formation of fine dust, the eutrophication (enrichment by excessive fertilisation) of the living environment (on land and at sea) and the acidification of busy coastal regions. They also give rise to the formation of the greenhouse gas ozone, which not only contributes to climate warming but can also cause significant respiratory problems. Enough reasons to take the fight against the emission of these substances seriously!
Federal attention to the fight against air pollution
The Belgian Coast Guard has already been using a so-called ‘sniffer’ sensor on board MUMM’s aircraft (Britten-Norman Islander, registration number OO-MMM) that is deployed over the sea to check for environmental and nautical violations since 2016. This sensor is an important tool in the fight against air pollution. Belgium was already in the international spotlight with regard to the enforcement of sulphur legislation, and in 2020 expanded its unique expertise to include the measurement of nitrogen compounds in emissions from ships at sea.
“For the purchase of the nitrogen sensor, my predecessor Philippe De Backer made a budget of € 70,000 available in 2019 to the Scientific Service Management Unit of the Mathematical Model of the North Sea (MUMM) of the Royal Belgian Institute of Natural Sciences (RBINS), which both owns and manages the Coast Guard aircraft. Also in my policy, we make the fight against air pollution above the sea a priority and we follow up this dossier closely”, says Minister Van Quickenborne.
When ships with suspicious sulphur or nitrogen levels in their emissions are detected, a report is drawn up and submitted to the port inspection services of the FPS Mobility. They then go on board and subject the ship to an extensive inspection. If irregularities are found, an administrative fine is imposed. By identifying suspect ships on the basis of air monitoring, port inspections and sampling can be carried out in a more targeted way, making them more efficient.
Nitrogen emission control area
On 1 January 2021, an Emission Control Area for nitrogen oxides (NOx) came into force in the North Sea and Baltic Sea. This so-called Nitrogen Emission Control Area (NECA) is part of the International Convention for the Prevention of Pollution from Ships (MARPOL), a convention of the International Maritime Organisation (IMO). Regulation 13 of MARPOL Annex VI defines the NOx emission limits for marine diesel engines as the amount of NOx per unit of engine power (expressed in g NOx per kWh).
Three emission levels are defined based on the date of construction (keel laying) of the ship, the so-called Tiers. Ships built between 2000 and 2011 have to comply with the Tier I standard (maximum 17g NOx/kWh), ships built after 2011 will have to comply with the Tier II standard (maximum 14.4g NOx/kWh). Ships built from 2021 onwards will have to comply with the strictest NOx standards of Tier III (maximum 3.4g NOx/kWh) in the NECA area. Ships built between 1990 and 2000 with a large engine capacity (>5000kW) or a cylinder size larger than 90l are also subject to the Tier I standard. No standard has been set for older ships. The aim is to achieve a gradual reduction of up to 80% in NOx emissions from ships sailing in these and other NECA areas by 2040.
For sulphur, too, there are control areas with strict standards, and Belgian marine waters have been part of the North Sea and Baltic Sea SECA zone (Sulphur Emission Control Area) since 2015. Since the NECA and SECA areas for the North Sea and Baltic Sea correspond geographically, from 2021 onwards we will simply refer to the North Sea and Baltic Sea ECA area (see map).
The NOx sensor
When a restrictive legal framework is not accompanied by adequate control mechanisms, the rules obviously risk remaining a dead letter. Until recently, the NOx regulations could only be enforced by checking the possession of a valid international air pollution prevention certificate, which had to be regarded as prima facie evidence of compliance. Also, the extent to which ships using emission reduction techniques (e.g. a catalytic converter) had activated their equipment in time before entering the ECA, and thus whether they were actually complying with the nitrogen regulations, could recently not be determined with certainty.
The new technology of the nitrogen sensor changes this situation. For the first time, accurate NOx monitoring can be carried out over the sea, and non-compliant ships can be identified with real measurements as proof.
Test results and future perspectives
The NOx sensor was extensively tested during the second half of 2020. “During 25 flights, we were able to successfully determine the nitrogen emissions of no fewer than 394 ships in Belgian waters!” clarifies Ward Van Roy, one of the operators of the Coast Guard aircraft. Of the ships monitored, about half were built between 2000 and 2011, and a third were more recent than 2011. The remaining ships dated from before 2000. “We found that the vast majority of ships monitored that must meet Tier I and Tier II standards from 2021 were already in compliance, but also documented some ships with nitrogen concentrations in their emissions that were more than double the limit. We are curious to see whether this will continue to be the case after the NECA is activated on 1 January 2021.” Van Roy adds.
Minister Van Quickenborne concludes: “Belgium was ready to carry out its enforcement role in nitrogen emissions from 1 January 2021. The first results can be considered a great success and give us confidence that we will be able to collect an enormous amount of information on nitrogen emissions from ships at sea. In the meantime, I have also released funds for the purchase of a sensor that can measure ‘black carbon’ emissions. This will be added to the aircraft’s equipment later in 2021 and will provide results that will help develop the necessary regulations within the IMO. We aim for 55% reduction by 2030 and climate neutrality by 2050. In this way, we are further expanding Belgium’s pioneering role in the fight against air pollution from ship emissions at sea.”
On Tuesday 24 November 2020, the Royal Belgian Institute of Natural Sciences (RBINS), Ghent University and the Research Institute for Agriculture, Fisheries and Food (ILVO) jointly organised the first Belgian Flat Oyster Day, as an online event.
A lot of information on several aspects of flat oyster restoration and aquaculture was presented during the event. The event demonstrated that an interest in flat oyster is emerging in Belgium, which was also illustrated by large audience (60+) that attended the event.
A report of the event has been compiled, containing the biographies of the speakers and the abstract of the presentations. Also the Q&A and poll results are included. Consult the report : Report_Belgian_Flat_Oyster_Day2020_Final.
The presentations are also available under the following links (the links are also provided in the report).
The interaction with the audience through the polls showed that there is a keen interest in the continuation of the Belgian Flat Oyster Day. In what format this will be, e.g. as a yearly event or as the creation of a Belgian Flat Oyster Consortium, in line with the Dutch initiative, is under consideration. To be continued.
We sincerely want to thank all speakers for their excellent presentations, and the audience for their attendance and enthusiastic participation in this online event!
A young minke whale that was washed ashore on Bredene beach on 11 December turned out to have a very unfortunate history: an empty stomach, intestines full of parasites and an abnormal spine. To make matters worse, two broken mandibles added to the problems. It is only the eighth minke whale that has been documented in Belgium during the past 20 years, and only the third stranding.
In the morning of Thursday 11 December 2020, the fresh carcass of a young minke whale (Balaenoptera acutorostrata) washed ashore on the beach of Bredene, near the border with Ostend. The animal, 3.89 m long (an adult minke whale can grow up to almost 10 m long) and weighing 489 kg, looked very skinny, and had a broken right lower jaw of which the bones protruded through the wound. A healthy specimen of the length of the Bredene minke whale should weigh about twice as much, so it was immediately suspected that it was in poor health even without fractures.
Autopsy reveals cause(s) of death
The carcass was immediately transferred to the Faculty of Veterinary Medicine at UGent, where a team from UGent and the ULiège performed an autopsy on 12 December. This post-mortem examination confirmed the poor condition of the unfortunate minke whale: no remains of a recent meal were found in the stomach, the digestive system was full of parasites and the spine showed abnormalities. The open fracture in the lower right jaw turned out to be less old than first suspected, and the lower left jaw also turned out to be broken. Eventually, the emaciation was not related to the fractures: the animal must have contracted them only very recently, and they were the result of a collision with an obstacle such as a vessel or a breakwater, or with the seabed.
Minke whales in Belgium
Although the minke whale is part of the North Sea fauna, its range is mainly limited to the northern and central parts of the North Sea. In recent years, however, they were more commonly observed in the south, probably due to changes in the marine ecosystem. “In Belgian waters, only seven proven cases are known to us from the last 20 years, three of which concerned carcasses while the other four referred to observations of live specimens.” explains Jan Haelters, expert on marine mammals at the RBINS. “The carcasses date from 2004 (found dead at sea and landed; died by bycatch), 2013 (stranded; died by swallowing a large amount of plastic) and 2017 (carcass in a far state of decomposition at sea). The live minke whales were observed in 2013, 2017, 2019 and 2020.” It is not known with certainty whether a number of reports from October 2020 actually concerned minke whales.
The skeleton of the Bredene minke whale will be preserved for science.
The cultivation of mussels in Belgian offshore wind farms is both biologically and technically feasible, according to research carried out by our scientists and their partners within the Edulis project. The economic feasibility depends on solving technical challenges.
After two years of experimentation and research, scientists and private companies present the results of the research project ‘Edulis: offshore mussel culture in wind farms‘, which looked at the possibilities for mussel farming in offshore wind farms 30 to 50 km off the Belgian coast. Edulis is a collaboration between Ghent University, the Research Institute for Agriculture, Fisheries and Food (ILVO), RBINS/OD Nature and 5 private partners (Belwind, Brevisco, C-Power, Colruyt Group and DEME Group). The ambitious pilot project is largely financed by private funding and facilitated by Flemish and European funding.
Quality Mussels
The project has demonstrated that it is both biologically and technically possible to cultivate mussels in the Belgian offshore wind farms, which means that these can serve more than one purpose at a time. The experiments resulted in a tasty quality mussel that is well stocked and meets all food safety requirements. The yield is equivalent to that of hanging mussels from the Netherlands and Ireland, and the mussels grow faster than mussels from bottom cultivation (mussels ready for market in 15 months instead of 24 months).
Technical Challenges
The big challenge is designing installations that can withstand the sometimes extreme North Sea environment. Investing in robust, easy to maintain and safe systems, including vessels, is a must, according to the researchers, although this will push up overall production costs. In addition, it turned out that the sizing and organisation of the wind farms is not optimal for food production, which is logical as they were not designed for that purpose. The distance from the coast also poses a challenge to technical, practical and economic feasibility. When designing future wind farms, this should be taken into account in order to be able to combine both activities.
Economic Feasibility
“Edulis has given us a clear picture of the costs and benefits of mussel farming in the North Sea” says Margriet Drouillon, Senior Business Developer Aquaculture and Blue Life Sciences at Ghent University. “If we really want mussel farming on a commercial scale, we will have to put a lot of effort into developing knowledge about the economic feasibility of mussel farming in the wind farms. We will also explore other paths for multiple use of space at sea, with due attention to sustainable production”.
Three Additional Challenges for Aquaculture in the North Sea
Ghent University and the Research Institute for Agriculture, Fisheries and Food (ILVO) launched the ‘North Sea Aquaculture’ project in 2017, with Edulis and Value@Sea as subsidiary projects. They joined forces with their partners RBINS/OD Nature, Belwind, Brevisco, C-Power, Colruyt Group, DEME Group, Lobster Fish, and Sioen Industries. North Sea Aquaculture tackled three challenges:
Innovative shellfish and seaweed farming techniques;
Efficient use of space in the Belgian North Sea;
The development of a market for new regional marine products.
Following the assessment of the ecological state of Belgian marine waters in 2018, monitoring has now been adapted for the second six-year cycle of the European Marine Strategy Framework Directive. The extension of the monitoring with a number of new partners and parameters will lead to a more complete understanding of the state of the Belgian marine area, and will help underpin a policy aimed at achieving and maintaining good environmental status.
The European Marine Strategy Framework Directive (MSFD) establishes a framework within which Member States document the state of their marine waters and take the necessary measures to achieve or maintain good environmental status. In this way, marine ecosystems throughout Europe are to be protected and, where necessary, restored.
DG Environment coordinates the implementation of the MSFD for Belgium. The Scientific Service Management Unit of the Mathematical Model of the North Sea MUMM (part of the Royal Belgian Institute of Natural Sciences) is responsible for the coordination of the monitoring and the assessment of the state, and cooperates with 7 other institutes (ILVO, INBO, FASFC, AFCN-FANC, VLIZ, Continental Shelf Service- FPS Economy and Ghent University; see partners).
A total of 29 monitoring programmes describe measurements in the various compartments of the marine environment using a wide range of techniques (from sampling by divers, analyses in the laboratory to aerial censuses and satellite observations). They contribute to the 11 themes (the so-called “descriptive elements”) defined in the MSFD. Eutrophication, fisheries, chemical pollution, waste and biodiversity of species groups and habitats are only some of the aspects addressed.
The newly included programmes include observations of plankton by VLIZ, seabed waste by ILVO, macrobenthos (organisms living on the seabed and visible to the naked eye) in the wind farms by Ghent University and radionuclides by AFCN-FANC.
Together, the measurements will make it possible to evaluate the state of the marine environment in Belgium and, where necessary, to define action points for a favourable future evolution.

The Leatherback turtle typically inhabits open and warm seas, where they mainly feed on jellyfish. They don’t easily show up In coastal areas (unless to lay eggs, but that is excluded on our beaches). Jan Haelters of the Royal Belgian Institute of Natural Sciences provides interpretation: “Leatherback turtles are very rare in the Belgian part of the North Sea: until now, only three strandings (1988, 1998 and 2000) and three sightings (2018 and 2 in 2019) were recorded. Although the list only counts seven specimens, an increase is noticeable in recent years.”
Also in the Netherlands
Remarkably, some Leatherback turtles were also seen in the Netherlands recently: one roamed the Eastern Scheldt from 22 to 24 September, while one swam along the North Sea coast of Scheveningen on 7 and 11 October. Comparison of the shape and size of the scars on the heads of the two animals, and of the ‘ribs’ on their back shields, shows that in Belgium and the Eastern Scheldt different individuals were involved. The Eastern Scheldt animal was washed ashore dead on 3 November near the Danish Ballum (article tvs).
Spatial planning is a discipline mostly associated with onshore built-up areas, but if there is one region in the North Sea that requires a rigorous mapping of activities it is the Belgian offshore area. Nature conservation, shipping, fishing, sand extraction, energy production, cables and pipelines, military exercises, … are all competing for space in this little patch of sea.
The Norwegian Expronews linked the Belgian marine spatial planning nicely with some of the RBINS work in relation to the assessment of reserves of certain abiotic resources and their potential for exploitation in a summarizing article.
Special attention is attributed to
the state-of-the-art 3D resource model that describes the distribution and availability of all non-hydrocarbon geological resources in the Belgian and adjacent Dutch marine waters, and can also serve as a resource decision support system and to underpin long-term adaptive management strategies (TILES, Van Lacker et al. 2019, Hademenos et al. 2019)
