Barge Master and Bosch Rexroth have jointly introduced an impressive new Motion Compensated Gangway (MCG) to the offshore wind market. After the design of a Motion Compensated Platform and a Motion Compensated Knuckle boom crane, we were also involved in the development of the detailed structural design of this Motion Compensated Gangway with a maximum operational stroke of 24 m.
The Motion Compensated Gangway compensates vessel motions in significant wave heights up to 3m by actively telescoping, luffing and slewing the gangway, the preferred way for safe and efficient crew transfer in offshore operations.
Due to tidal variations and difference in height of offshore structures, the entire Motion Compensated Gangway is able to vary in height utilizing an Eccentric Height Adjustable Pedestal (EHAP). This pedestal enables to keep the angle of the gangway close to horizontal. The connection between the EHAP pedestal and Gangway can lock itself to the height of the offshore structure, while a fully integrated internal elevator system in the EHAP pedestal allows step less transfer of personnel and cargo from any ship deck level.
After numerous simulations and virtual tests, the first actually manufactured gangway was installed on the offshore support vessel VOS Start of fleet operator Vroon.
“With this solution, users are able to transfer people and goods from ship to platform 24 hours a day, 7 days a week, making this solution far better than anything available on the market at this moment. I am confident that, together with Bosch Rexroth, we will optimally serve the offshore wind market with this next generation gangway.”
