FAQ 1: What type of vessel , and how is it transported?
Answer: She is a non-self-propelled steel grab dredger designed for operations in coastal zones. Since she lacks its own propulsion system, it must be towed by a tugboat for both transit and deployment. During towing, the vessel is unmanned, and all windows and doors must be securely closed to ensure watertight integrity. The crane boom must also be lowered or stowed and fixed before transit.
FAQ 2: Is the vessel built according to international classification standards?
Answer: Yes, the design and construction of this grab dredgegr is strictly adhere to recognized standards. It complies with the statutory inspection rules of the Maritime Safety Administration of China (2020 edition with 2022 amendments). The vessel is certified for domestic coastal navigation and meets specific requirements for freeboard, tonnage measurement, materials, welding, and safety equipment (including life-saving and fire-fighting appliances).
