Many wind turbines for marine applications must comply with API, LIody above and below Deck and classification society standards. Fans in ships/ocean ships often require stainless steel structures, and ship anti-paint spraying must be used to withstand high salt environments. Offshore/offshore platforms belong to the petrochemical field, and there are requirements for explosion-proof safety standards, so it is recommended to use explosion-proof motors. Applications include ventilation and exhaust fans in the space below the deck, boiler induced draft fans/exhaust fans, etc.
