What is H2Flow?

Born offshore, built for offshore

H2Flow is a cloud-based operating system purpose-built for offshore marine contracting — managing the complete lifecycle of assets, maintenance, crew, and vessel operations. Built for the way offshore teams actually work, from the Party Chief managing crew changes on a vessel bridge to the Asset Manager tracking equipment across a global fleet. H2Flow replaces fragmented spreadsheets, legacy desktop software, and disconnected tools with a single, modern platform accessible from any browser or tablet.

Real operational experience

Every workflow reflects how offshore operations actually run — not how a product manager imagines they should.

Priority surface, depth on demand

You land on exactly what needs your attention today. The full system is one deliberate click away — not buried in menus.

IMCA-aligned compliance

Competency frameworks built around IMCA C001–C005 from day one. Container tracking supports DNV 2.7-1/2.7-2 and CSC certification requirements.

Natural language AI

Ask the Bosun anything in plain language. No filters, no navigation required — the AI interrogates every module in parallel and surfaces the answer.

Built by a survey engineer, not a software house

The platforms available for offshore operations were built by people who have never worked the deck. They are overcomplicated, poorly suited to vessel workflows, and require significant training just to do basic tasks. H2Flow was designed by an experienced offshore survey engineer who got tired of fighting the tools and decided to build the right one.

Secure offshore data and access control

Your identity, your control

Offshore has a thorny identity problem: rotating freelance crew, shared vessel-role mailboxes used by different people week to week, and clients who run their own corporate directories. H2Flow handles both ends — people sign in with the accounts they already have, and you still know exactly who did what, even behind a shared login.

  • Sign in with Microsoft 365 / Entra ID or Google out of the box, with other SAML 2.0 / OIDC providers configured on request — no separate password directory, and your IT keeps central control of access and offboarding
  • Per-person PINs on shared vessel-role logins — the mailbox stays read-only until the individual unlocks it with a PIN sent to their own personal email
  • Every change attributed to the real person in a tamper-evident, append-only audit trail
  • Strict per-company data isolation via PostgreSQL Row-Level Security, hardened across multiple penetration-test rounds

Every piece of kit, always accounted for

From mobilisation to demob, H2Flow tracks every asset across your entire fleet — vessels, warehouses, and offices. Scan a barcode to raise a transfer, report a fault, or view full documentation. When equipment moves, its documentation follows automatically. Client audits go from stressful to straightforward.

  • Searchable asset register with 3-tier equipment categorisation
  • Barcode & QR scanning — scan to identify, transfer, fault or maintain
  • Label generation — print barcode and QR labels in multiple sizes
  • Auto-updating Master Document Register per vessel
  • 14-stage fault resolution lifecycle with root cause analysis
  • Packing containers — scan a flight case or pallet box, fill it with scanned assets, ship with a full contents manifest see how →
  • Location barcodes — scan a shelf or storage zone to place equipment away without touching a PC
  • Container & module register with full certification lifecycle
  • Sub-location & warehouse 2D layout editor
  • Meter & counter tracking with threshold-based maintenance triggering

Maintenance that follows the equipment, not the calendar

Most PMS systems treat equipment as if it never moves. H2Flow knows that a Macartney winch sitting in a warehouse doesn't need its monthly checks — but it will the moment it's mobilised to a vessel. Schedules suspend on demobilisation, reinstate with recalculated due dates on mobilisation, and the entire transition is audit-trailed.

  • Calendar and meter-based scheduling — running hours, cycles or dive counts trigger maintenance alongside date intervals
  • Location-aware lifecycle — schedules auto-suspend at land locations and reinstate with recalculated due dates on mobilisation
  • Work orders with parts bill-of-materials, labour assignments, hourly rates and cost tracking
  • Critical-spares readiness — nominate the spares each job needs, see what's on hand before you start, and get alerted the moment planned or corrective work draws a critical spare below its minimum
  • Pre-mobilisation verification gate — equipment must pass its checks before dispatch to a vessel
  • Template library with intervals, checklists and instructions — create once, schedule across the fleet
  • Bulk schedule actions — multi-select to reschedule, reassign or mark complete in one operation
  • Role-based experience — Asset Managers see fleet-wide schedules and templates; vessel crew see My Tasks scoped to their vessel
  • ISO 55001:2024 aligned — lifecycle-appropriate, risk-based scheduling with documented condition assessments
Offshore vessel safety equipment

Your crew, certified. Your compliance, watertight

H2Flow tracks every crew member's certifications, competencies, and rotation status across your fleet. IMCA-aligned competency frameworks, automated expiry alerts, and crew change planning that generates travel tasks automatically — so nothing slips through.

  • IMCA C001, C003, C004 & C005 competency frameworks
  • Certification matrix with fleet-wide expiry monitoring
  • BARS & ILUO assessment methods with gap analysis
  • Per-role competency trees with external assessor sign-off
  • Training recommendations generated automatically from competency gaps
  • Diving records — IMCA D014, hyperbaric & DMAC medical certs
  • Crew calendar — Gantt timeline, scrum board & planning panel
  • Crew change planner with auto-suggestion of replacements
  • Travel planning with auto-generated tasks and batch booking
  • Self-service personnel portal for crew

Every fault the fleet solves
makes the next answer sharper

When a sensor drops out on the back deck at 3am, the watchkeeper wants an answer — not a ticket queue. H2Flow's AI first-line responds instantly, but never from memory: every suggestion is retrieved from your own equipment manuals and the faults your fleet has already solved, and it cites the manual and page. When it can't ground an answer, it escalates rather than inventing one.

No more operational blindness

The moment a normal purchase order is emailed off, the vessel goes dark. You can't see whether it's been picked up, where it sits in the process, or when it will land — not until it appears on deck, or you start chasing it down by phone and email. H2Flow closes that gap. Crew add what they need to the vessel's weekly order sheet — a critical spare, or the everyday consumables that keep a vessel working: cable ties, self-amalgamating tape, Molykote, rags and wire — and every line carries a live status the whole way: requested, sent to procurement, on order, shipped, received. Anything urgent breaks out of the weekly cycle instantly. Nothing happens out of sight.

01

Requested

Crew add items to the vessel's weekly order sheet — a critical spare or everyday consumables. Duplicate-order checks flag anything already on its way.

02

Sent to procurement

At the weekly cutover — or the moment someone hits 'send now' — the sheet goes to shore procurement. Urgent items break out and go straight away.

03

On order

Procurement places the order with the supplier. The line flips to 'on order' — visible from the vessel.

04

Shipped

Marked shipped once it's on the move, so the deck knows what's inbound and roughly when.

05

Received

Auto-stamped on goods receipt — booked straight into stock, spares or the asset register.

Urgently Required, fast-tracked

Flag an order as Urgently Required and it breaks out of the weekly cycle immediately, firing an instant alert to the people who can act on it. No waiting, no blind spots.

Approve by value, not by habit

Set the threshold once. Routine spend never waits on a signature; only the orders that matter get stopped.

Critical spares, never caught short

Nominate the spares each maintenance job needs and set minimum and maximum holdings per vessel. The moment planned or corrective work draws a critical spare below its minimum, the right people get an alert — and a fleet-wide spares register shows exactly what's held, where, and what's running low.

Native or ERM-connected

Works standalone today, and writes back to IFS, SAP or Maximo as the ERM integration lands.

The foundation every module is built on

The modules above are only half the story. Every H2Flow subscription is built on a shared foundation of native tools that every user relies on — the connective tissue that keeps a vessel's information controlled, accurate and audit-ready, whichever modules you run.

Document Control

Controlled documents, current every time. Upload a new revision of an equipment manual and the old one is retired automatically — the crew, and the AI first-line, always work from the current issue, never a stale PDF taped to the rack. And every change across the platform is captured in a tamper-evident, append-only audit trail, attributable to the real person even behind a shared vessel login.

Document Register

Every asset's documents, always current and always to hand. An auto-updating Master Document Register per vessel gathers each asset's calibration certificates, FAT certificates, equipment manuals and compliance records — tied to the asset, with expiry tracking and a renewal workflow that assigns the chase before anything lapses. When equipment moves between vessels, its documents move with it, so a client audit is a matter of filtering, not hunting.

Vessel Network Mapping

Living isometric diagrams of every vessel's switches, servers, survey sensors and satellite links — each node linkable to a real asset. No Visio, no stale rack PDFs.

Configuration Trees

Map any survey spread, ROV system or towed array pin-by-pin on a photo, nest sub-assemblies to any depth, and clone the build across the fleet — each vessel filling the slots with its own kit.

Mobilisation Profiles

Define what "ready" means for each job type — the exact kit, certs and configuration it demands — then check any vessel's readiness against the profile before it sails.

Sub-location Mapping

Know exactly where equipment lives — down to the shelf, rack bay or deck zone. Scan a location barcode to place kit away or find it in seconds, no PC required.

Cable Pin-out Diagrams

Document every connector and pin-out as a clear visual reference, so terminations and break-outs are right first time on deck — and the next engineer isn't guessing.

Label & Barcode Generation

Generate and print barcode & QR labels in any size — for any asset, container or shelf location. The backbone of the scan-to-track workflow that runs right across the platform.

Hands-on, right here

Map every spread, pin by pin

Every survey spread, ROV system or towed array is a web of components that changes each mobilisation. H2Flow lets you map it visually: upload a photo of the kit, drop numbered pins on each part, and drill down into sub-assemblies. Build a configuration once and clone it across the fleet — then each vessel fills the slots with its own specific equipment, so you can see at a glance what's onboard, what's missing, and what needs attention.

Map the whole vessel. Drag, drop, done.

Every vessel runs a sprawling web of switches, servers, survey sensors and satellite links — and it changes every mobilisation. H2Flow's built-in isometric network mapper lets your team document it visually: drag devices onto the canvas, wire them together, and keep a living diagram that travels with the vessel inside The Lighthouse. No Visio licences, no stale PDFs taped to the rack.

A simplified taste — the full mapper goes far deeper: a drag-and-drop device-icon library, multi-layer diagrams, VLAN/subnet and IP registers, rack elevations and cable-pinout references, with every node linked to a real asset.

Works with your ERM. Or without it.

H2Flow is the operational system of record for vessel work — the equipment, the maintenance, the crew, the day-to-day. It's built to sit alongside the ERP/ERM you already run, not rip it out. Your ERM owns finance and master data; H2Flow owns the operational lifecycle — and the two stay in sync.

IFS · SAP · Maximo

Plug into your ERM

Bidirectional integration with IFS, SAP and Maximo through an adapter pattern. Operational events — goods receipts, stock moves, work orders — flow back to finance, while master data flows in. IFS Cloud integration is in active development.

No ERP required

Or run it standalone

No ERM? No problem. H2Flow runs perfectly as your single source of truth for assets, maintenance, crew and procurement — ideal for leaner operators who don't carry enterprise ERP overhead. Add an ERM later; nothing has to change.
