Run offshore operations from one system of record.
Subseacore unifies crew logistics, rig operations, contracts, payroll, and compliance for oil & gas operators and contractors — built for the realities of offshore work, not adapted from generic enterprise software.
Deployed for operators & contractors managing offshore crew, assets, and contracts
Every offshore workflow, one system of record.
Nine connected modules replace the spreadsheets, inboxes, and disconnected tools most operators and contractors are still running offshore logistics on. See the full platform →

Most logistics tools assume one network covers a route end to end. Offshore routes rarely work that way — a Marine option might only exist for the first leg, out to a connecting hub. Subseacore searches both networks in parallel and stitches a combined itinerary when no single network covers the whole journey, instead of quietly defaulting to the more expensive option.
- Marine and General networks sourced in parallel, not sequentially
- Automatic hub-and-connection routing when no direct route exists
- Every recommendation shows the reasoning behind it, not just a price
An AI-assisted recommendation, not a black box.
Best Flight is Subseacore's AI-assisted recommendation engine. On every search it weighs the full Marine and General result set against price, duration, and layover time, then surfaces the one it would book — and shows exactly why, instead of asking an admin to trust a badge.
- Ranks by price band, speed, and layover — not lowest price alone
- Reasoning shown on every card, not hidden behind a score
- Recalculates instantly as fares move — never a stale cache
Offshore logistics doesn't fail because people aren't working hard enough. It fails because the record of what's true lives in six different places at once.— The Subseacore team, on why we built one system of record
How teams put the platform to work.
Illustrative scenarios built from real Subseacore workflows — not audited results from named customers yet. See all scenarios →
One login instead of five vendor portals.
A North Sea operator gets a live, account-scoped compliance view across four marine crewing contractors — without asking any of them to change tools.
Illustrative — ContractorSix client accounts, one system, zero cross-over.
A marine crewing contractor runs every client's roster and logistics from one login, fully isolated by account, by default.
Illustrative — ProjectA 10-week project, without a new system to stand up.
A decommissioning project tracks budget against real bookings and exports its close-out report directly, not by hand.
Access control built around how contractors actually work.
Multi-tenant by design — every client company's crew, projects, and rigs stay pooled and scoped to their own account, never leaking across operators sharing the platform. Read more on Security →
Account-scoped data pooling
Admins sharing a client account see each other's crew, projects, and rigs. Admins outside it see nothing — no manual permission wiring required.
Three-tier role model
Command, admin, and crew each see exactly what their role requires — down to which actions are visible, not just which pages load.
Retained, not deleted
Deactivating a contractor blocks their login without erasing the crew, projects, or history they created — your operational record stays intact.
Full audit trail
Every booking, assignment, and document change is traceable to who did it and when — ready for compliance review, not reconstructed after the fact.
From mobilization to reconciliation.
Mobilize crew
Assign roster to a rig or project and see availability update in real time across the account.
Source logistics
Search Marine and General networks together, with combo routing when no single network works.
Track compliance
Certifications and documents stay visible against expiry — before they block a mobilization.
Reconcile
Payroll and client billing calculate markup and cashback automatically from the same source data.
