TSHD at Barkmeijer Shipyards

Alewijnse Marine electrical outfitting TSHD Barkmeijer Shipyards, part of Thecla Bodewes Shipyards.

Alewijnse Marine has reached agreement on the restart of the complete electrical installation works on board a trailing suction hopper dredger (TSHD) currently in build at Barkmeijer Shipyards. A new customer was found after the take-over of the insolvent Barkmeijer by Thecla Bodewes Shipyards. Works in Harlingen are now in full swing with delivery scheduled for March 2020.

Scope Alewijnse

Alewijnse Marine, the leading specialist in marine electrical and automation technology, is responsible for the design, building, installation and commissioning of the switchboards and consoles on board the dredger, and of the dedicated alarm, monitoring and control systems. 


Martin Terpstra, Operational Manager at Alewijnse Marine, is very pleased with the assignment. “We are very happy that Thecla Bodewes Shipyards has given us the opportunity to complete this dredger and has indicated that they will retain us for the second vessel that will follow this one. We look forward to demonstrating our electrical and automation expertise on this project and to delivering a state-of-the-art vessel to its new owner. This is the first time that we have worked with them. This project also has major significance for the shipbuilding industry in the Northern Netherlands, including maintaining employment and continuity for the suppliers.” 

Advanced TSHDs

The TSHD under construction is one of two dredgers that was taken over by Thecla Bodewes Shipyards following the insolvency of Barkmeijer Shipyards. The new customer will use the specialised dredging vessels for the offshore extraction of sand and gravel aggregates. The dredgers are 105.9 metres long, have a beam of 15.85m and a maximum draught of 6.94m. Each has a single suction pipe and a hopper capacity of 3,000m³, and accommodation for fourteen people. The advanced dredgers will have diesel-electric power plants to significantly reduce energy consumption and emissions.

Success through cooperation

Thecla Bodewes Group and Alewijnse Marine had worked together successfully for many years. Recently completed projects included the German wadden ferry Adler Rüm Hart, which can sail very efficiently with a capacity of 250 passengers and an empty ship weight of only 78 tonnes. Other, earlier, joint projects included the delivery of the hopper dredgers UKD Orca (2010) and Charlock (2016), the offshore accommodation barge Elikia (2014) and and three pilot station vessels built for the Dutch Pilots’ Organisation; the Polaris, Pollux and Procyon (2012 - 2014). Alewijnse was contracted again for the latest TSHD due to its extensive knowledge and experience combined with the long and strong relationship with Thecla Bodewes.
