The Indonesian navy has claimed a crude leak and subsequent fatal fire last month was caused by a bulker's anchor rupturing a pipeline.
The 82,000-dwt Ever Judger (built 2014) was damaged in the blaze on 31 March at Balikpapan.
Five fishermen were killed in the incident, which was possibly caused by one of their discarded cigarettes, or by workers trying to burn the oil away.
