The three-purpose workboat, built by Keppel Shipyard in Singapore, features 18000 horsepower, DP II dynamic positioning, 206 tons bollard pull, and a large deck operating area. It meets requirements for large-scale towing, deep-sea replenishment, and other operations. The vessel is equipped with an advanced wave-compensating gangway, which maintains balance and stability in unstable wave or sea conditions. The wave-compensating gangway plays a key role in offshore wind power, offshore oil and gas exploitation, and ship loading/unloading operations, helping to maintain operational stability, improve work efficiency, and reduce risks. This technology is very important for various engineering and operational tasks in marine environments.
