Anchoring and mooring systems for tankers and bulkers

摘要

Ruggedness, efficiency, and smooth control arc all primary requirements for anchoring and mooring systems in the tanker sector, with a choice of electric or hydraulic drives to suit different vessels. Low-pressure hydraulic winches remain popular for tankers and hulk carriers, despite a more recent growth in the use of high-pressure hydraulic drive systems for some vessels. In recent months, one leading deck machinery supplier, Rauma Brattvaag, part of Rolls-Royce's Ulsleinvik, Norway-based marine division, has won a string of contracts to supply LNG tankers with low-pressure hydraulic anchor and mooring winch sets for new ships. With orders from leading owners, including Golar LNG, Bergesen ASA, Petronas, and Malaysia International Shipping, projects last year took the company's reference list to 28 in this sector. Capacity of the vessels involved range from 130,000m~3-140,000m~3.
