Standards quick-map
Which document governs what – and where each one deliberately stops and leaves the decision to you. Every row links to our full analysis.
| Document | What it governs | Where judgment starts | Our analysis |
|---|---|---|---|
| IHO S-100 / S-101 IHO | The framework replacing S-57 for hydrographic data products; S-101 is the new electronic navigational chart standard now entering service. | Timelines and dual-fuel transition periods: what contractors must change now versus what can wait is a reading of rollout phases, not of the standard text alone. | S-100 Phase 1 is live |
| IMCA S 026 IMCA | Out-of-straightness (OOS) survey requirements for pipelines – methods, accuracy expectations and reporting for lateral-buckling assessment. | Where survey method choice meets structural engineering need: what the document specifies versus what the integrity engineer actually requires of the data. | IMCA S 026, unpacked |
| IMCA M 203 IMCA | Simultaneous operations (SIMOPS) – managing multiple, often separately contracted parties working the same site at the same time. | The document assumes somebody owns the combined picture; contracts frequently ensure nobody does. That seam is where combined operations fail. | Separately contracted, same deck |
| IOGP SSDM IOGP | The Seabed Survey Data Model (Report 462) – the schema that lets survey deliverables land in operator GIS systems as data rather than drawings. | Version transitions: what changes for data teams when the model moves, and how deliverables specified against the old version age. | SSDM version 3, examined |
| DNV-RP-0585 DNV | Recommended practice for marine site investigations – the reference many operators now cite when scoping seismic and site survey campaigns. | A recommended practice is not a contract: which of its demands belong in your scope of work, and at whose cost, remains a client decision. | What it demands of site survey scope |
| ASOG Industry practice (MTS/IMCA lineage) | Activity-Specific Operating Guidelines for DP operations – the decision table that defines vessel status (green/blue/yellow/red) against system state. | Following ASOG is necessary, not sufficient: the drift-off cases worth studying are the ones where the table was green and the position was still lost. | Why following ASOG still fails |
Document identities are verified against the issuing bodies per our editorial policy. This map lists the standards our published analysis covers; it grows as the corpus does, and it is a reading aid – always work from the issuing body's current edition, not from any summary, including this one.
