Offshore Crew Vessel

Offshore support and crew transfer vessels

We design for superior seakeeping and improved comfort, up to 20% saving in fuel consumption for equivalent vessel payloads, novel hull forms for improved docking performance, minimum weather downtime and high payload capacity.

We are valued for our robust, fuel-efficient designs and our reputation as global innovators.

Crew Transfer Vessels

CTVs are explicitly designed to transport service teams to offshore wind farms.  They have become more prominent, more robust to service wind farms further offshore and are usually fitted with bow fendering explicitly suited to wind turbines.

All our CTVs are designed to be efficient and work effectively in various offshore environments.  Advanced hull forms such as our XSS (eXtreme Semi-Swath) provide that capacity along with improved seakeeping and operability.  Our larger offshore fast crew boats also deliver class-leading fuel efficiency for the oil and gas market.

We’re continually increasing the range of available sizes of our proven CTV designs from 18 metres to over 30 metres.  New, longer vessels meet the industry’s growing demand for capacity and prolonged offshore operations. 

Offshore Support Vessels

OSVs can be divided into several types according to operations they perform: seismic survey ships, platform supply vessels (PSV), anchor handling tugs, anchor handling tug and supply vessels (AHTS), offshore construction vessels (OCV), ROV support vessels, dive support vessels, stand-by vessels, inspection, maintenance and repair vessels (IMR) and variety of combinations of these.

Our platform supply vessels are designed for servicing offshore drilling rigs and production platforms with the necessary equipment, stores and drilling consumables.

OSVs may have additional cabins, mess room facilities, and offices to accommodate the support crews comfortably.

Active Fender System®

Beyond hull design, we aim to improve operability through Turbine Access and Active Fender Systems.  These significantly help reduce the potential for impact damage to either the vessel or turbine structure and enhance the safety of the technician transfer. We consistently strive to refine our vessel designs and have an extensive research and development program for all vessel types.

Our designs

We have an ever-expanding range of proven vessel designs in our portfolio, including vessels ranging from 9m to 220m in length and speeds of up to 70 knots.
