Jan De Nul orders another newbuild trenching support vessel.

Jan De Nul orders another newbuild trenching support vessel. September 21, 2026, by Nadja Skopljak Jan De Nul is further expanding its fleet with the order of a new trenching support vessel, which will be an exact copy of its Isambard Kingdom Brunel, announced in March. With this latest order, Jan De Nul has five vessels under construction for subsea cable installation and protection, including two XL cable-laying vessels (CLVs), an XL rock installation vessel to protect the cables, and now two vessels for the burial of cables. Isambard K. Brunel, announced in March, is of an Ulstein design and will be built at the China Merchants Heavy Industry (CMHI) shipyard. Both vessels will be capable of burying cables in the seabed up to five meters deep, will be equipped with ultra-low emission (ULEv) technology and will be able to run on biofuel, besides being prepared for future operation on methanol. "Our two new cable-laying vessels will soon enter the market. The Fleeming Jenkin has completed her first sea trials and is now in the final construction phase. The William Thomson will follow shortly," said Wouter Vermeersch, Director Subsea Cables Offshore Energy at Jan De Nul. "The investments in vessels that can protect these cables at the same pace are a logical next step. Last year, we already announced the order of the rock installation vessel George W. Goethals, which protects cables and other energy infrastructure with a layer of rock. With the Isambard K. Brunel and this new sister vessel, we are also adding two vessels for burying cables in the seabed. This will bring our fleet to a total of fourteen vessels for the installation and protection of subsea cables," Vermeersch noted. Jan De Nul is also working on the conversion of an existing vessel, Henry Darcy, from a water injection dredger into a trenching support vessel. It will carry the Crayfish subsea robot, specialized in burying cables in shallow water. Power your brand with Offshore Energy.

Jan De Nul introduces Crayfish, a new subsea robot trencher.

Jan De Nul introduces Crayfish, a new subsea robot trencher. By the end of 2026, Crayfish will join the Jan De Nul fleet of trenchers. This new subsea robot can bury cables up to five metres deep in the seabed and is ideally suited for working in shallow waters, closer to shore. Once completed, Crayfish will have a permanent home aboard Henry Darcy, which is currently being converted into a trenching support vessel. Like the Swordfish, which Jan De Nul uses to bury cables in deep waters, the company ordered Crayfish from British engineering company Osbit. Capable of burying cables in water depths of up to 200 metres, the trencher can be deployed flexibly, both offshore and onshore. Thanks to its lightweight design and modular build, Crayfish has a limited impact on its surroundings. Its modular design also makes it easy to transport and mobilise from one project to another. Conversion of Henry Darcy. Crayfish is remotely operated from the shallow-draught vessel Henry Darcy, which is currently being converted into a trenching support vessel. Before its conversion, Henry Darcy was a water injection dredger, using high-pressure water to loosen the seabed and move sediment. Today, part of this former equipment is being given a new purpose. The water pumps previously used for dredging will supply high-pressure water to Crayfish. The jet water is fed from the vessel to the trencher through a hose, allowing Crayfish to loosen the seabed and bury the cable. This smart combination makes Crayfish particularly well suited to shallow waters. On most trenchers, the jet pumps are located on the machine itself, but they cannot operate in very shallow water. On Crayfish, the pumps are located aboard Henry Darcy, allowing the trencher to work much closer to shore. First deployment in 2027. Crayfish will be deployed for the first time in summer 2027. In the German North Sea, the trencher will bury cables in shallow waters as part of the 2 GW cable programme Jan De Nul is carrying out for grid operator TenneT. The arrival of Crayfish is part of a series of recent investments in the expansion of the company's subsea cable fleet. It will strengthen Jan De Nul's capacity to install and protect subsea cables and further contribute to the development of infrastructure for renewable energy at sea.

Jan De Nul expands subsea cable capability with shallow-water trencher.

Jan De Nul expands subsea cable capability with shallow-water trencher. 12 hours ago 'Crayfish' will be deployed from converted trenching support vessel Henry Darcy on TenneT's 2GW German North Sea programme. Jan De Nul is expanding its subsea cable installation fleet with a new remotely operated trencher designed specifically for cable burial in shallow water. Named Crayfish, the subsea robot is due to join Jan De Nul's trenching fleet by the end of 2026. It will be permanently deployed from Henry Darcy, a shallow-draft vessel currently being converted from a water injection dredger into a dedicated trenching support vessel. Built by UK engineering specialist Osbit, Crayfish will be capable of burying cables to depths of up to 5m in water depths of up to 200m. Its lightweight and modular construction is intended to reduce its impact on the seabed while allowing the unit to be transported and mobilised between projects. The system has been configured specifically to overcome one of the limitations of conventional trenching technology in shallow water. Rather than carrying its high-pressure jet pumps on the trencher itself, Crayfish will receive pressurised water from pumps installed aboard Henry Darcy. The pumps are being repurposed from the vessel's previous role as a water injection dredger. High-pressure water will be transferred through a hose to Crayfish, loosening the seabed ahead of the trencher as it advances along the cable route. Jan De Nul said locating the pumps on the support vessel allows Crayfish to operate closer to shore, where water depths can prevent conventional trencher-mounted jet pumps from operating effectively. The unit's first deployment is scheduled for summer 2027 in the German North Sea, where it will support Jan De Nul's 2 GW cable programme for German transmission system operator TenneT. The project forms part of the company's broader expansion of its subsea cable installation and protection capabilities. Jan De Nul fleet. Jan De Nul has invested heavily in its offshore energy fleet over the past several years. Its existing cable-laying fleet includes Isaac Newton, Connector and Willem de Vlamingh, while two 28,000-tonne cable-laying vessels, Fleeming Jenkin and William Thomson, are being added in 2026. The 215m vessels are designed to install cables in both shallow and ultra-deep water, including at depths of up to 4,000m. The company is also adding dedicated vessels for cable protection and burial. Jan De Nul says four vessels are being added to its subsea energy cable fleet, with one existing vessel undergoing conversion. The expansion reflects the growing importance of subsea cables to offshore wind development and cross-border electricity interconnection. Jan De Nul's new cable-laying vessels, for example, are being deployed on TenneT's programmes to connect offshore renewable generation to the electricity grid. With Crayfish and Henry Darcy, Jan De Nul is adding a more specialised shallow-water capability to that fleet, extending its ability to install and protect subsea cables through the transition from deeper offshore waters towards the nearshore environment.

Jan De Nul begins dredging for strategic Anaklia Deep Sea Port in Georgia.

Jan De Nul begins dredging for strategic Anaklia Deep Sea Port in Georgia. Posted on August 31, 2026 Alternative trade route Located on Georgia's Black Sea coast, Anaklia Deep Sea Port will increase the country's capacity to handle large container vessels and create additional capacity for dry and bulk cargo. The port will boost the development of the Middle Corridor. This trade route through the Caspian and Black Seas is considered a reliable alternative to the northern route through Russia, or the southern route via the Suez Canal. Two dredging vessels at work Jan De Nul's dredging vessels Tristão da Cunha and Al-Idrisi are deepening the access channel to 17.5 metres, allowing the port to accommodate large Panamax and Post-Panamax vessels. Panamax vessels are designed to fit the maximum dimensions of the original Panama Canal, while Post-Panamax vessels exceed these dimensions. The works also include the construction of a turning basin, giving these large vessels sufficient space to safely manoeuvre within the port. In a joint venture with local company Prime Concrete, Jan De Nul will also construct a breakwater of 1,380 metres. The structure will protect the port from waves, creating a sheltered area where vessels can safely enter, manoeuvre and berth. First vessel in 2029 Dredging works will continue until the end of 2026. The construction of the breakwater should be finished by the end of 2027. The first construction phase should be completed by 2029 The port will then have an annual container capacity of at least 600,000 TEUs, short for Twenty-foot Equivalent Unit, a standard measure of the capacity of container ships and ports. A second phase is expected to increase this capacity to at least one million TEUs by 2035. Tamar Ioseliani, Deputy Minister of Economy and Sustainable Development of Georgia:"The Government of Georgia has a well-organized and consistent vision and plan for developing the country's transport system to expand Georgia's role in international transport and logistics networks. We will ensure that the Anaklia Deep Sea Port receives its first ship in 2029."
