24 cable & pipeline work in force

Cable laying, pipeline and seismic operations.

What the archive shows

The available cable & pipeline work archive contains 17,642 messages across 29 issue years, from 1998 to 2026. The year links below provide the source and sea-area breakdowns for each period.

The current list includes messages issued from 2024-10-28 to 2026-09-28. A warning can remain in force for an extended operation, so this list is not a list of new incidents.

nga_inforce accounts for 13 of 24 recorded messages (54%), the largest source in the current list group in this selection.

The NGA archive froze in 2024-05; live collection began 2026-08-17. Counts near that gap are incomplete. Separate messages may describe updates to the same activity.

Terms used in cable ops warnings

Underwater operations
Divers or remotely operated vehicles are working below a vessel that cannot easily move out of the way.
Cable operations
A ship is laying, burying or repairing a submarine cable, usually along a stated route.
Offshore wind farm
Construction or maintenance at an offshore wind farm: turbine foundations, jack-up vessels and export cables.
Anchoring and fishing prohibited
Ships may pass but must not anchor, trawl or put gear on the seabed — usually because of cables, pipelines, moorings or ordnance.
