Abstract
PT. Z operates the largest shipping fleet in Indonesia to transport various products such as crude oil, fuel oil, gas products In line with the Government’s commitment to support the domestic maritime industry and ensuring cargo transportation all over Indonesia. Transportation of oil and gas through these vessels must not be interrupted, that is why the company also has responsibility to ensuring that the vessels always in good conditions and also pay more attention to accidents that may occur on the ship, one of the accidents that can occur on a tanker is in the form of a fire and explosion in cargo area causing by flammable gas accumulation due to the absence of an inert gas system or the inert gas system not functioning on board. Fire can happen when all of the elements in fire triangle are existed. Fire triangle elements are oxidizers, fuel, and heat source. When tank cleaning, loading or discharge cargo is the most likely moment for oxygen to enter the tank, there is a risk of causing an explosion if there is a heat source around the tank. Therefore, to control the atmosphere in the tank so that the oxygen content does not reach an amount sufficient to form a fire, an inert gas system is installed, inert gas system will maintain the tank atmosphere by inserting inert gas into the tank. while inert conditions are conditions where oxygen levels in cargo tanks are maintained at a maximum level of 8% of the total volume of gas present in the tank's atmosphere. In addition, the inert gas system must be able to produce inert gas with an oxygen content of less than 5% by volume of pure inert gas (BKI, 2018) Losses that can be caused by the explosion of tanker include fatalities due to accidents, economic losses due to loss of cargo and ships, spills of oil, gas and other chemicals that cause environmental pollution, and can also result in fuel and gas scarcity. Therefore, it is very important to keep the inert gas on the ship operates as it should be. One of the solutions is by doing the maintenance of system perfectly. There is one systematic approach for determining the maintenance requirements of plant and equipment in its operation is called Reliability-Centered Maintenance (RCM), RCM will chooses the right maintenance activities such as preventive maintenance or corrective maintenance for the right equipment at the right time to reach the most cost-efficient solution. After RCM analysis is done there are 40 tasklist, and the percentages of every maintenance types of each failure mode are 70% preventive maintenance, 22.5% condition monitoring, and 7.5% One-time change.
