Turbine access systems provide access to the turbine from a CTV or SOV. Systems are designed to permit access to the turbines in as wide a range of sea-states as possible, in the interests of maximising possible maintenance time and turbine availability.
What it costs
Costs typically included in vessel costs.
Who supplies them
Ampelmann, Fjellstrand, Houlder, Osbit, Uptime and Windcat Workboats.
Many SOV turbine access systems are based on motion-compensated gangways that react in real time to changes in the sea surface, providing a stable platform to allow personnel to walk from the vessel onto the turbine. Motion compensating gangways have been trialled on CTVs.
Such systems are designed within operational limits and do not permit access in the most severe sea states.
