SUBMARINE CABLES AND PIPELINES
Mariners are reminded not to anchor, trawl or carry out any activities affecting the seabed in the vicinity of submarine cables and pipelines. Mariners risk prosecution if they damage submarine cables or pipelines.

Submarine cables additional to those charted may exist. Repaired sections of submarine cables may lie a distance away from the charted submarine cable positions. Mariners are also warned that the seafloor where cables were originally buried may have changed and cables become exposed. See The Mariner's Handbook.

Submarine pipelines are not always buried, and their presence may significantly reduce the charted depth. Submarine pipelines may also span seabed undulations and cause fishing gear to become irrecoverably snagged, putting a vessel in severe danger. Gas from a damaged submarine pipeline could cause an explosion, loss of a vessel's buoyancy or other serious hazard. See The Mariner's Handbook.

Mariners are also advised not to anchor or trawl within 1750 metres from the submarine cables and pipelines in Indonesian waters.
