Osbit Ltd has recently delivered a height adjustable boat landing system to Gulf Marine Services’ self-elevating support vessel (SESV) GMS Endeavour currently deployed on Ørsted’s Hornsea Project One wind farm off Yorkshire.
According to Osbit, this is the offshore industry’s first height adjustable boat landing system for a jack-up vessel.
The system has five height settings that enable it to be accessed in line with the vessel’s jacked up position, across the full tidal range. Its height, relative to the vessel deck, is adjusted using GMS Endeavour’s 230-tonne capacity on-board crane.
“The specific challenge presented by our client for this project required our vessel GMS Endeavour to remain elevated at a height of 15.1 metres above sea level, while at the same time providing the capability to safely dock a CTV against the vessel, and then ensure the transit of up to 200 passengers per day from the CTV to the main deck of GMS Endeavour,” Duncan Anderson, Chief Executive Officer of Gulf Marine Services, said.
“Our solution was to design and produce an integrated CTV boat landing and access tower specifically for our SESV. To date, the structure and its interface to GMS Endeavour has been designed, built, installed and finally approved in accordance with classification requirements. We have been very pleased with the entire process, with GMS Endeavour now operational at the Hornsea Project One wind farm.”
Fabricated on the banks of the River Tyne and assembled at Osbit’s facility at the Port of Blyth in North East England, the 26.4 metre tower system was delivered within a five-month project timeframe, as part of the vessel’s mobilisation programme.
Osbit’s engineers also completed the installation of the boat landing system on GMS Endeavour at Port of Blyth. The installation took place ahead of GMS Endeavour’s deployment to support Hornsea Project One offshore wind farm, which is located 120 kilometres off the Yorkshire coast. The vessel is providing accommodation and access to substations for technicians working on the wind farm project.
