Scope

Scope: This document specifies the classification principles, methods, and categories of offshore wind power operation and maintenance vessels (referred to as "operation and maintenance vessels"). This document applies to the production, trade, leasing, and maintenance of ships used for operation and maintenance tasks in offshore wind farms. Offshore photovoltaic and marine ranching operation and maintenance vessels may refer to this classification. Main Technical Content: (Reference) Characteristics of Operation and Maintenance Vessels A.1 Wind Power Transport Vessels Wind power transport vessels have the following characteristics: a) Overall length: Generally not less than 25m, or customized according to client requirements; b) Loading capacity: Not less than 12 personnel and conventional tools, equipment, and spare parts, with a deck loading capacity of not less than 30T; c) Operation and maintenance reachable distance or area: Coastal navigation and near-sea navigation (equipped with SOVs); d) Propulsion system: Water jet propulsion, conventional rudder and propeller propulsion, adjustable pitch propeller propulsion systems; e) Seakeeping: Single-hull vessels are inferior, while twin-hull and tri-hull vessels are better. A.2 Operation and Maintenance Mother Vessels (SOVs) SOVs have the following characteristics: a) Overall length: 60m–90m, or customized according to client requirements; b) Crew capacity: Not less than 50 personnel; c) Operation and maintenance reachable distance or area: Near-sea navigation and unlimited navigation areas; d) Propulsion system: Full-azimuth podded rudder and propeller propulsion systems; e) Operation and maintenance vessel configurations include but are not limited to: accommodation and living facilities, DP positioning systems, large cargo decks, cranes, operation and maintenance workboats, wave compensation gangways, boarding platforms, geographic information systems (GIS), aluminum alloy helic
