SMST has won a contract from Damen Shipyards Group to supply two sets of mission equipment for Windcat Offshore’s two newbuild Elevation Series Commissioning Service Operation Vessels (CSOVs).

Through the provision of a Telescopic Access Bridge L-Series gangway, combined with an Access & Cargo Tower and the world’s largest 3D Motion Compensated Crane, SMST claims it has enhanced the flexibility and capability of the hydrogen-powered vessels, which have already gained recognition for their ground-breaking design.

The SMST mission equipment that will be in operation on board the CSOVs from 2025 contains the first ever 10t 3D motion compensated crane

The Elevation Series CSOVs are a result of the collaboration between Damen, Windcat and CMB.TECH, with SMST playing a crucial role in the design and integration of vessel equipment.

“SMST has been closely involved in the design of the vessels, which has enabled us to optimally integrate our equipment,” said Menno de Jong, Sales Manager at SMST. “This has resulted in the most efficient and safest logistic solution for the CSOVs, and it has also created an optimal construction process for the equipment on board.”

Scheduled for deployment from 2025, the SMST equipment deployed on the CSOVs includes the world’s first 10-tonne 3D motion compensated crane, the largest of its kind globally. De Jong emphasised the enhanced offshore handling capabilities offered by this particular crane variant, saying it would enable even more efficient execution of offshore wind farm construction.

SMST’s contribution to these environmentally friendly CSOVs comes in the form of their most energy-efficient mission equipment to date. Joost van der Weiden, Sales Manager Benelux at Damen Shipyards, said.

“We are committed to building sustainable vessels and we believe with their offshore systems on board, SMST can support us in achieving this goal,” he said. “Together we have developed an industry-leading design setting an example for the energy transition in the offshore wind sector.”

Stephen Bolton, managing director at Windcat Offshore, highlighted the range of motion compensated gangway, combined with the tower and elevator, which reaches up to 30 metres above sea level.

He emphasised the importance of SMST’s equipment in ensuring safe, efficient, and seamless routing of personnel onboard the CSOVs.
