Engineering Service We deliver complete subsea engineering design packages — not just software. You get signed reports from a senior engineer.
Who It's For Any company who need fast, standards-compliant structural, pipeline, or geotechnical engineering and documentation.
How It Works Send us your design basis. We run automated calculations, review results, and return signed reports — typically within days.

Input → Automate → Report

Every project follows a rigorous AI-assisted pipeline. Engineering parameters are ingested, domain-specific AI workflows apply international design standards, and complete design reports are generated — then verified by a senior engineer before delivery..

Standards-Compliant

Every calculation module encodes the full logic of international design standards. No LLM manual formula lookups, no spreadsheet errors — just validated, traceable engineering. RAG-powered retrieval connects each calculation directly to the source standard text — pulling the exact clauses, tables, and commentary from DNV, ISO, and NORSOK documents in real time — so every output is anchored to the governing reference, not just the formula derived from it.

Complete Design Reports,
Generated in Hours

Every report includes design basis, full detailed calculation traces, load summaries, methodology, and compliance statements — Company formatted, checked by a senior engineer and ready for client delivery.

Structured Calculations

Step-by-step calculation traces with equation references to code clauses.

Unity Check Tables

Automated pass/fail matrices across all load combinations.

Compliance Summaries

Traceable references to every DNV/ISO/NORSOK/ASME clause applied.

Validation & QA: Every automated result is independently reviewed by a senior engineer before delivery. Calculations are verified against analytical benchmarks and third-party tools.
