46 CFR Subchapter L · OSV
Subchapter L — Offshore Supply Vessels
compliance, handled.
Offshore supply vessels are a hybrid — cargo vessel, workboat, and personnel carrier at once — and they operate in a heavily-scrutinized environment where the records get examined from two directions: the Coast Guard and the energy charterer's vetting. Binnacle AI keeps the recurring load current across a rotating offshore crew.
What Subchapter L asks of you
Specific to the vessel's service, route, and persons-carried limits.
OSVs carry heavy, shifting deck cargo and liquids — stability and the cargo/ballast picture are central.
Credentialed crew for the tonnage, horsepower, and route, plus the offshore workers carried in addition to crew.
Equipment appropriate to offshore service and the persons aboard.
Logged on schedule, plus a 46 CFR 16 / 49 CFR Part 40 program.
Evidence that satisfies both a Coast Guard boarding and a charterer's vetting.
How Binnacle AI handles it
- Per-vessel COI and survey scheduling with lead-time alerts.
- Credential expiry tracking across a crew that rotates offshore.
- An AI document scanner that reads MMCs and certificates from a photo.
- Drill logs and OFAC SDN crew screening.
- A one-click Insurance Package that doubles as charterer-vetting documentation.
- An audit-ready evidence trail for both the Coast Guard and the charterer.
