Operational knowledge. Available onboard. Open to scrutiny.
Propel built Full Fathom AI so crew can ask a question in plain English and get an answer from their own approved documents, with its source alongside it. Everything runs onboard, including when the vessel has no connection to shore.
Empowering your crews when they need it most.
Crew, fleet managers, designated persons ashore and HSEQ teams.
Prepare the ship’s library ashore
Approved documents become a versioned knowledge pack. Procedure steps, tables and surrounding context stay together, and onboard answers draw only from that pack.
Find the relevant, authoritative passage
Search considers meaning and exact wording. The vessel’s safety management system takes priority, followed by fleet procedures, regulations and reference material. Mandatory procedures are returned in full and in order.
Answer only what the documents support
References are checked against their passages, with a separate check that the evidence is sufficient. High, Medium or Low confidence comes with a reason; missing support leads to a clear “not covered”.
Work at sea and update in port
Questions are answered locally on vessel hardware. Updated knowledge packs are checked when loaded; sharing with the office follows the operator’s rules, and personal crew details are excluded from the question log.
See the situation.
Follow the evidence.
Useful views connect the operational overview to the records and decisions behind it.
Crew member
Read the answer beside its source, document version and uncertainty, without a separate search.
DPA and HSEQ team
Review the questions, sources and checks recorded for each answer to support audits and incident reviews.
Fleet manager
See recurring questions and unanswered topics across vessels, then target the documentation that needs improvement.

The basis stays visible.
Full Fathom AI is available now. Approved procedures and the judgement of the people responsible remain central to its use.
- Approved passages and their knowledge version
- Citation validation and separate evidence-sufficiency checks
- Warnings, uncertainty and a route to specialist review
