Tanker and SPM Motion Response Analysis due to Environmental Load

Abstract

The use of tankers for oil and gas distribution requires auxiliary structures such as Single Point Mooring (SPM). In the process of loading cargo, tankers must maintain a level of stability so that the load transfer process runs smoothly. Stability needs to be checked using inputs in the form of structural responses in free-floating conditions to get structural responses when moored. Analysis of the motion response of tankers and SPM in free-floating conditions showed that ballast tanker loads had a greater motion response than full loads with the largest movement on roll at 3.59 deg/m. The moored motion response of the tanker has the greatest amplitude in the surge movement towards the AP with a value of -0.2251 m.
