In the shipbuilding fatigue life is an analysis that is often overlooked which causes the unknown of the operating life of a ship. This research discusses the calculation of the tanker fatigue life. The problem formulations are how is the stress distribution and also how is the fatigue life of the tanker. This calculation is to determine the age of a tanker construction so that it can be a reference to determine the age of the ship in the future. The procedure used in this research is by modeling ${\textstyle\frac{1}{2}}$+1+${\textstyle\frac{1}{2}}$ cargo oil tank construction from frame 55 till frame 115 using finite element method modeling. The method of fatigue life calculation is simplified fatigue assessment method. The rules or standard used is CSR 2012 standard and the ship subject of this research is 17500 LTDW Crude Oil Tanker Ship. The results showed that the greatest stress occurred at the meeting between hopper plates and doublehull plates in the frame 104 with a value of 30,647 Mpa. The calculation results show that the life of the ship is 27, 53 years. This age still accepted by 2012 CSR standard, which is a 25-year design life standard. (Abstract)
