An effective anchoring plan can prevent anchor accidents and avoid any operational failure.Ī detailed risk assessment of the anchoring operation should be carried out to formulate an effective plan and to make prudent decisions when facing emergencies. Risk assessment and plan to anchorĪnchoring operation is part of a passage plan, which must be carefully planned, executed and monitored. Some newly laid oil pipelines or gas pipelines might not be marked/updated on the navigation chart and Notices To Mariners.Įmergency anchor dropping might also be necessary in case of steering failure, probable collision, maneuvering in shallow waters, etc. The ICPC (International Cable Protection Committee) bulletin point out that anchor dragging whilst at anchor or under way can cause underwater cable damage, and the cause of such damage around the world has been closely monitored since the formation of ICPC. There are no definite criteria to measure it. The distance to the nearest grounding line should be no less than one nautical mile.Ī safe distance between vessels depends on vessel's maneuverability that could be restored from anchor dragging. To avoid accidents like anchor dragging, vessels should keep a safe distance from other vessels, navigational hazards, underwater cables and pipelines. Surroundings of anchoringĪlong with evaluating the nature of the seabed when anchoring, these are the elements to be considered: direction and strength of wind and current, sea condition, shallow water, prohibited areas, navigational aids and facilities, underwater cables and pipelines, swinging room, other anchoring vessels in the vicinity. Ship companies should set up procedures for these critical tasks and incorporate them into the safety management system. It includes anchoring planning, risk assessment, best anchoring practices, anchoring watch keeping, etc. Good bridge management in anchoring operations is the key to achieving safe anchoring and avoiding accidents.
