The Flemish government, Port of Antwerp and contractor SeReAnt (a partnership between the Jan De Nul GROUP and DEME environmental companies) will begin dredging and processing the most polluted dredging sludge at the port, the so-called TBT sludge, this month. “After years of research, there is now finally a solution to this historical pollution. This is a worldwide first and a milestone for Flanders and Port of Antwerp,” says Lydia Peeters, Flemish Minister of Mobility and Public Works. “We will remove the most contaminated sludge from the docks. As a result, water quality will improve substantially.”

Pollution from ship paint

The Flemish government and Port of Antwerp are keeping the docks of the port of Antwerp accessible for contemporary shipping together. Every year, enormous quantities of sludge are dredged for this purpose and then processed by the AMORAS dewatering installation. “But there was one type of sludge we couldn’t process yet: sludge with elevated organotin concentrations or Tributyltin, or TBT sludge for short,” says Yi-Bin Shan, Head of the Maritime Access Department at the Department of Mobility and Public Works.

“TBT had been used worldwide in ship paint since the 1970s to prevent the growth of mussels and algae on hulls, but has been completely banned since 2003. After all, the product is enormously harmful to the environment and is also difficult to break down. The sludge has been storing TBT like a sponge all these years and is gradually releasing this contamination. This is disrupting the metabolism and hormone action of molluscs in particular, such as snails and mussels.”

Only port in the world

“Along with the University of Antwerp, we have been investigating for several years how to get TBT out of the port,” says Jacques Vandermeiren, Port of Antwerp’s CEO. “We are proud that we can finally tackle this historical pollution. Currently, the water quality in the docks scores below the European standard. This project will greatly improve it. As a port authority, we believe it’s important to take responsibility in respect of society. This makes us the only port in the world that not only removes polluted sludge, but also processes it sustainably.”

The Flemish government and Port of Antwerp are jointly releasing the necessary resources for dredging and processing the most polluted dredging sludge. “Flanders makes 25 million euros available annually for the operation of AMORAS. We are now making an additional investment of 700,000 euros a year to dispose of TBT spoil in an ecologically responsible manner. This way, we can increase the accessibility of the port, an important task for the Flemish government,” says Flemish Minister Lydia Peeters.

“Port of Antwerp has invested 1 million euros in the preliminary phase of this project and will release 1.5 million euros a year for the effective processing of TBT spoil,” port alderman Annick De Ridder continues. “Port of Antwerp wants to be an inspiration for other ports and take a pioneering role in the field of sustainability”.

800,000 m³ of sludge over the next five years

Processing the total quantity of polluted sludge at the port of Antwerp is a long-term task. A pilot project was started in 2018 after obtaining the necessary permits and some modifications to the water treatment plant. “We have added an extra step to our processes and installed activated carbon filters. These filter the toxic substances out of the water after it passes through our treatment plant,” says Yi-Bin Shan, Head of Maritime Access.

“During that pilot project, we had already dredged, transferred and processed 185,000 m³ of heavily contaminated sludge on AMORAS. In this way, we were able to properly map out the impact on the installation and all possible risks. Now, there is an agreement to remove 800,000 m³ of sludge from the harbour docks over the next five years and process it into 500,000 tonnes of filter cake. We’ll first remove the sludge that obstructs nautical access and the worst TBT hotspots in the older, southern part of the port. Then we’ll deal with the other areas.”

How will this work?

  1. The contaminated TBT spoil is dredged at the port. With a 15 m³ environmental grab, the spread of pollution in the surrounding water is avoided.
  2. The dredging sludge is transported in 2,400 m³ transport containers to the AMORAS processing plant.
  3. SeReAnt, the contractor operating the AMORAS plant, extracts the sludge from the transport containers and pumps it into the treatment plant.
  4. Coarse dirt and sand are removed.
  5. The waste water is purified via a water treatment plant. TBT sludge is also purified by activated carbon. Then the water flows back into the docks.
  6. The sludge is processed into a dry end product: filter cakes that are safely stored on site.

AMORAS: innovative cooperation between government, port and dredging companies

Through AMORAS, the Flemish government and Port of Antwerp are working together on the sustainable and long-term storage and processing of maintenance dredging sludge from the Antwerp docks. AMORAS stands for Antwerp Mechanical Dewatering, Recycling and Application of Sludge.

The Department of Mobility and Public Works provides 80% of the funds, while Port of Antwerp provides the other 20%. Since 2011, the dewatering plant has been processing 450,000 tonnes of dry matter into filter cakes every year. The temporary trade association SeReAnt operates the installation. SeReAnt is a collaboration between the environmental companies DEC of Deme Group and Envisan of Jan De Nul Group. AMORAS is constantly looking for solutions for re-using the dry matter obtained from non-polluted dewatered sludge in useful applications. There are several routes, but the concrete industry in particular is showing interest in the filter cakes.

Milaha, one of the largest Maritime and Logistics Organizations in the Middle East, has entered into a formal agreement to cooperate with leading American oilfield services firm, Schlumberger Limited.

The Offshore & Marine pillar of Milaha signed a Memorandum of Understanding (MoU) that will support value building projects while jointly driving Tawteen initiatives for Qatar. Led by Qatar Petroleum, the “Tawteen” program aims to localize the energy sector’s supply chain and create new investment opportunities to retain ‘economic value’ in Qatar.

Signed as a five-year joint development project, it will include a Qatar-owned, Qatar-flagged and Qatar-operated Oil Well Stimulation Vessel. The first of these vessels will be designed and outfitted in the country, creating the inaugural FLEXSTIM platform, which will be modified, owned and operated locally.

Pre-engineering for this significant scheme has already begun and will evolve during the final quarter of 2020.

The resulting Qatar-owned value chain will be a joint service that enhances the expertise of a global multinational service firm like Schlumberger as well as the leading Qatar-based multi-disciplined local service company like Milaha.

With over 70 years of presence in Qatar, Schlumberger supplies the petroleum industry with several key services such as seismic acquisition and processing, well testing and directional drilling, artificial lifts, well completions and groundwater extraction.

The Hamburger Hafen und Logistik AG (HHLA) is taking a majority stake of 50.01 percent in the multi-function terminal “Piattaforma Logistica Trieste” (PLT) in the Italian seaport of Trieste. An agreement was signed on 28 September. The investment will be allocated contractually and organisationally to HHLA International GmbH. With this investment, HHLA is positioning itself in a growing market on the Adriatic whose strategic position offers great opportunities for development. This will be HHLA’s third participation in a port outside Hamburg after Odessa (Ukraine) and Tallinn (Estonia).

Angela Titzrath, Chairwoman of HHLA’s Executive Board: “The Adriatic region has been developing very dynamically in the past few years. As the northernmost port in the Mediterranean, Trieste is the southern gateway to Central and Eastern Europe. The investment is a strategic expansion to our existing port and intermodal network. The terminal gives us the opportunity to actively participate in and help shape new and changing cargo flows and underline our ambitions to grow internationally. At the same time, we will continue to enhance our terminals in Hamburg by investing in facilities and technology. We are a Hamburg company, at home in Europe and operating globally.”

Francesco Parisi, Chairman of PLT’s Executive Board: “HHLA’s participation strengthens the growth prospects of PLT and of the entire Port of Trieste. Our development strategy in the direction of Central and Eastern Europe fits in with HHLA’s orientation. The position of the new partners confirms us in the development of the terminal expansion we are pushing ahead with.”

The terminal facilities are within the Free Port of Trieste and take up a total area of 28 hectares. In the northern part of the facilities, mainly general cargo transports and logistic services are being handled. The new heart of the terminal is emerging in the southern part: the newly developed area will start operations in the first quarter of 2021 and is designed to handle container and RoRo traffic. The capacity of the PLT terminal will then comprise a total of approximately 300,000 TEU (standard containers), 90,000 RoRo units and 700,000 tonnes of general cargo. There is also the option to significantly expand terminal capacity through additional adjacent areas.

The strategically relevant position of the Port of Trieste on the Adriatic also allows for excellent development opportunities in hinterland transport. The PLT terminal has its own rail connection. The HHLA rail subsidiary Metrans already connects the Port of Trieste with its European intermodal network.

The transaction is subject to various conditions precedent and is expected to close in January 2021.

Boston-based Sea Machines Robotics announces today that it has partnered with shipbuilder Metal Shark Boats, of Jeanerette, Louisiana, to supply the U.S. Coast Guard (USCG)’s Research and Development Center with a new Sharktech 29 Defiant vessel for the purposes of testing and evaluating the capabilities of available autonomous vessel technology.

The 29-foot, welded-aluminum monohull pilothouse vessel comes equipped with the Sea Machines SM300 autonomous-command and remote-helm control technology, offering the USCG a full range of advanced capabilities – including transit autonomy, collaborative autonomy, collision avoidance and remote vessel monitoring.

The RDC helps transition innovative technologies and provides premier analysis and decision support to enhance operational performance across all Coast Guard missions. During demonstrations scheduled for October off the coast of Hawaii, the RDC team will test and evaluate the Sharktech vessel’s autonomous capabilities for their potential in supporting USCG surveillance, interdiction, patrol and other missions. Following the Hawaii demonstrations, the autonomous vessel will be returned to the RDC’s New London facility, where it will be used in additional testing to investigate application to various Coast Guard missions.

“As the premier USCG facility performing research, development, test and evaluation in support of the service’s major missions, the RDC team is eager to observe Sea Machines’ system in action,” said USCG’s Derek Meier, assistant demonstration director. “The exercises will ultimately help us determine how, when, and if this innovative technology can be used to support personnel who are executing a variety of Coast Guard activities.”

“Sea Machines is proud to actively support government agencies across a variety of projects and to expand that support to the Department of Homeland Security with this important demonstration being conducted by the U.S. Coast Guard,” said Sea Machines’ Phil Bourque, director, sales. “Our systems are being rapidly adopted by government and commercial operators alike, offering increases in on-water productivity and predictability, while reducing operational risk.”

“Since the launch of our Sharktech Autonomous Vessels division in 2018 we have been working to position Metal Shark for the autonomy revolution,” said Metal Shark’s CEO Chris Allard. “We are committed to the advancement of autonomous technology, through our relationships with leading autonomy suppliers as well as through our own R&D, and we are engaged with multiple customers, from the USCG, the Department of Defense and commercial operators. With this latest delivery, Metal Shark is proud to play a role in the Coast Guard’s autonomous technology R&D efforts.”

In 2019, Sea Machines partnered with Metal Shark to make available the Sharktech 29 Defiant vessel to commercial markets, under Metal Shark’s stock boat program. Most recently, in July, Sea Machines partnered with Huntington Ingalls Industries to accelerate the deployment of self-piloting technologies in the rising market of unmanned naval boats and ships.
