Your Project's
AI Engineer.
Available 24/7.

Project-specific AI trained on your work packs. When an offshore technician calls with a fault at 2am, SubsAI knows the project, reads the documentation, and guides the resolution — before anyone gets woken up.

The Problem

The answer exists.
Nobody can find it at 2am.

Offshore platform North Sea
North Sea operations

An offshore technician calls in at 2am. The vessel is on standby. The client is furious. The on-call engineer who answers is not the right specialist.

The right answer is sitting in a document somewhere — the commissioning record, the fault history, the controls philosophy document. Nobody can find it under pressure at 2am on a moving vessel.

This happens on every project. The cost is real. The information already exists — in your work packs, your commissioning records, your fault history. The problem is access, not knowledge.

Downtime Is Expensive
Vessel standby costs per day can be costly on subsea projects. SubsAI will reduce downtime and costs.
How It Works

Three steps.
One call resolved.

SubsAI ingests your project work packs and makes them instantly queryable in plain language. The AI does not make decisions — your engineer does. SubsAI delivers the right information, instantly.

01
We Ingest Your Work Pack

SubsAI ingests your complete project documentation — work packs, commissioning records, fault history, vendor manuals, approved procedures. Combined with built-in knowledge of industry standards (ISO, API, DNV, HSE, OGUK) and oil and gas engineering best practices, every project gets a genuine AI engineer — not a document search tool.

02
Engineer Asks a Question

Your engineer asks in plain language. SubsAI draws on project documentation AND its built-in knowledge of industry regulations, standards and best practices to give a complete, accurate answer — the way a senior specialist would.

03
Resolution or Briefed Escalation

Most faults resolve without waking anyone up. When escalation is needed, the human engineer receives a full briefing — fault description, relevant data, applicable standards, steps already taken. The decision always stays with your engineer.

Every agent is trained on your project documentation plus the regulations and standards that govern your operations — HSE, UKCS, OGUK, ISO 13628, API, DNV, NORSOK and more. The agent knows industry law and best practice as well as your specific project. That is what makes it an AI engineer, not a search tool.

SubsAI in action.

Fault scenario: Low IR readings on subsea controls cables — 02:14 offshore

What just happened

An offshore technician detected low IR readings on the SCM to TUTU flying lead on Tree 4. Instead of calling the on-call engineer at 2am, they asked SubsAI.

SubsAI retrieved the commissioning baseline, compared it to the current reading, identified a precedent fault on the same project, and provided the isolation procedure — all from the project work pack.

  • Commissioning baseline retrieved in under 5 seconds
  • Previous fault history on Tree 2 identified immediately
  • Isolation procedure pulled from Section 7.4 of the Controls Operations Manual
  • No engineer woken up. Vessel standby avoided.
SubsAI // Project Specific
02:14
Offshore Technician
Getting low IR readings on the controls cable between SCM and TUTU on Tree 4. Reading is 2.8 megohms. Is that acceptable?
SubsAI Engineer
Commissioning baseline for the SCM to TUTU flying lead on Tree 4 was 48.2 megohms at first oil. Minimum operational limit for this cable type is 10 megohms per the project controls philosophy document. Your reading of 2.8 megohms is below the operational minimum.

Tree 2 had a similar reading in March 2023 — resolved by replacement of the wet mateable connector at the TUTU interface. Do you want the isolation procedure?
Offshore Technician
Yes — what's the isolation procedure?
SubsAI Engineer
Section 7.4, Controls Operations Manual: Confirm tree in safe state — all valves closed. Notify topsides before disconnection. ROV to disconnect flying lead at TUTU interface. Cap and bag both connector faces immediately. Log in controls fault register. Notify Subsea Controls Engineer before any reconnection attempt.

Do you need the connector torque specifications?
The Return

One avoided standby day. Years of SubsAI.
