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.
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.
PR #42 with the calculation note + inputs.The thing practising engineers actually need from AI: the same answer every time, traceable to a clause, defensible in review.
Every result maps to a DNV / API / ISO / ASME clause. 42 standards implemented.
Reproducible by construction — same input, same output, no model drift.
It states what it assumed and where the scope ends — AI that shows its work.
Free, browser-based tools built on international standards — the same engine Deckhand runs. No signup required.
On-bottom stability per DNV-RP-F109. Hydrodynamic loads, submerged weight, utilisation ratio.
Try CalculatorBurst and collapse checks per ASME B31.4. Multi-code comparison with corrosion allowance.
Try CalculatorS-N curve fatigue analysis per DNV-RP-C203, API RP 2A, BS 7608 with interactive plotting.
Try CalculatorYour 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.
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.
Your OrcaFlex and standards expertise lives in the heads of 1-2 senior engineers. When they're unavailable, projects stall.
Each maps to a live Deckhand channel you can try on Open Deck.
