The AI engineering firm
for offshore energy.

Deckhand drives real engineering work — analysis, documentation, issues and pull requests — straight from a chat message, executed by an AI agent under hard, auditable guardrails. Standards-traceable. Deterministic. It shows its work.

Built on the open-source digitalmodel library — 7,000+ standard-mapped functions, 42 standards implemented, ~30 engineering disciplines.

Meet Deckhand

Ask an engineering question in plain language. Deckhand runs the real calculation — against the right standard — and returns a deliverable with every assumption traced. Changes to code or docs arrive as pull requests, never silent edits.

  • AI that shows its work — assumptions, standards, and scope limits on every result.
  • Deterministic — same input, same output, audit-ready.
  • Governed — PR-only, no force-push or deletes; everything out of scope returns 404.

Wall thickness for a 12" pipeline, 10 MPa design pressure, X65 — DNV-ST-F101?
Minimum wall 9.5 mm (incl. 1.0 mm corrosion allowance). Governing check: pressure containment, DNV-ST-F101 (2021) §5.4.2. Utilisation 0.81.
Assumptions: SMYS 450 MPa, tfab −12.5%, no buckling check requested. Full note & PR ready on request.
Add the local buckling check.
Done — combined loading per §5.4.4 passes (utilisation 0.88). Opened PR #42 with the calculation note + inputs.

Deterministic by design

The thing practising engineers actually need from AI: the same answer every time, traceable to a clause, defensible in review.

Standards-traceable

Every result maps to a DNV / API / ISO / ASME clause. 42 standards implemented.

🔢

680 byte-identical cases

Reproducible by construction — same input, same output, no model drift.

Sound Familiar?

Manual Iteration Hell

Your engineers spend 3+ hours per day on repetitive OrcaFlex model setup and results extraction. A 50-case sensitivity study takes a full week of tedious work.

🤖

AI You Can't Defend

Generic chatbots give a different answer every time and cite nothing. You can't put that in a calculation note or hand it to a checker.

👥

Knowledge Concentration Risk

Your OrcaFlex and standards expertise lives in the heads of 1-2 senior engineers. When they're unavailable, projects stall.
