Service Operations Vessel — a specialist vessel used in offshore wind operations to transport, accommodate, and support maintenance technicians for extended periods at sea. SOVs have motion-compensated gangways (walk-to-work systems) that allow safe personnel transfer to turbine platforms in wave heights up to 2.5–3 metres. Typically accommodating 60–120 technicians, SOVs have transformed the economics of offshore wind O&M by dramatically reducing weather downtime.
