Wind Energy – CTVs
BMT has won a design contract for three new Crew Transfer Vessels (CTVs) to be operated at east coast wind farms in the US.
The three vessels will be built by Senesco in the USA under ABS classification meeting USCG subchapter L regulations.
The 88ft (27m) CTV design is suited for operating conditions on the US’ east coast and features a lightweight Z-bow hull form to improve seakeeping characteristics as well as offer very high efficiency thereby reducing emissions.
The vessel utilizes Active Fender System (AFS), designed and customized by BMT, to facilitate both monopile and conventional landing tube transfers.
“Fitted to the bow of the vessel, the AFS operates as a suspension system which reduces impact loads and dampens the initial engagements with the turbine tower, guaranteeing successful landing in the most difficult weather conditions, and the layout is such that it can also accommodate the latest GUS technician hoisting system for increased safety,” BMT explained.
The vessel is propelled by quad Volvo IPS 900 which deliver speed performance reaching up to 26 knots, combined with bollard thrust in excess of 15 tonnes while maintaining outstanding manoeuvrability, BMT says.
