CTVs (Crew Transfer Vessels) are now a significant vessel class, designed specifically to transport personnel & Technicians, to service Offshore Wind Farms.
The majority of CTVs (Crew Transfer Vessels) have been designed to be efficient and effective and built to work in the sector. They are usually aluminium catamarans accommodating 12 passengers. Transit speeds range between 15-25kn although some vessels have a top speed of up to 30kn. Recent experience has shown however that comfort is more important than speed, enabling personnel to do their work effectively when they arrive at the windfarm!
CTV's have become large & more robust in recent years to service the Round 2 & 3 Windfarms, further offshore. Most are now also specially fitted with bow fendering suited specifically to wind turbines.
