What happened

Pertamina's subsea crude pipeline across Balikpapan Bay ruptured and released a large oil slick that ignited on the water, killing five people and prompting a local state of emergency. Indonesia's transport-safety investigation found that the bulk carrier MV Ever Judger's anchor had dragged and displaced the pipeline by roughly 120 metres before it failed. The spill and fire damaged coastal and marine habitat, including mangroves and aquaculture areas, and became one of Indonesia's most consequential recent industrial pollution events. This was an accidental anchor-strike and pipeline failure, not sabotage. Public estimates of the released volume varied substantially, so the record does not merge them into a false single figure.

When cited sources give different casualty, damage or spill figures for this event, they’re reported side by side above rather than merged into one number. See how confidence levels work.
