Analysis of Valve Leaks in Cargo Lines in MT. Bull Damai 1
Abstract
The necessity for petroleum in Indonesia is very large every year. Of course, in the process of equal distribution across all area in Indonesia, effective and efficient transportation is needed, i.e. tanker vessel. The condition of a vessel greatly influences the smooth distribution of petroleum. When the author carried out sea project on the MT. Bull Damai 1, author found a cargo of crude oil that cannot be sucked by the cargo oil pump. It turned out that this was influenced by damage to the valve on the cargo pipe in the tank. The aim of this research was to determine the factors that cause damage to valves on cargo pipes and to determine the maintenance of valves on cargo pipes so that cargo discharging results will be maximized. From the research results, it can be seen that insufficient maintenance of the valves on the cargo pipe can cause the valve to become damaged. In this research, one part of the valve, namely the seat ring, was torn, which caused the valve to not be tight and allowed air to enter the cargo oil pump system, so that the cargo oil pump cannot suck the cargo until it runs out (dry). Factors that cause valves on cargo pipes to be damaged are lack of maintenance by the vessel’s crew, poor valve operation which results in cavitation and water hammering, over running hours, and valves that cannot be closed completely. Maintenance is carried out by referring to the PMS (Planned Maintenance System) and the ship's manual, operating manual, and paying attention to the effects of water hammering and cavitation.
