Subsea Pipeline Damaged in Balikpapan Bay Caused by Anchor Load

Abstract

Balikpapan Bay is an important and dangerous due to five oil subsea pipelines divide the waters of Balikpapan-Penajam Paser Utara to supplied crude oil to Refinery Unit V Balikpapan. In the end of April 2018, one of the subsea pipelines was damaged caused more than 40,000-barrel spill at the Balikpapan bay. It was suspected due to anchor load of a ship. This paper discusses the effect of anchor load on a damaged subsea pipeline in the bay of Balikpapan. In this study, data was collected from many resources and simulated using Subsea Pipeline Pro Software. The simulation results are compared to the field data where the subsea pipeline shifts about 113 meters from its original position by forming V shaped with a degree of 61
