Water supply is the safest bulk supply operation but it must comply with certain hygienic standards. Potable water tanks must be solely used for this purpose, maiataiaed under vessel s planned maintenance plan and audited under International Safety Management (ISM). Pumps and pipework should be flushed with super chlorinated water and than with fresh potable water prior refilling tanks. Hoses used for water transfer should be dedicated for this purpose and cleaned with chlorinated water on weekly basis. Each year hose need to be replaced. Water in potable water tanks of PSV typically may be stored for 7 da3 . After this time water is transferred to drill water tanks. Specific rules regarding water quality management usually are given in national regulations.
