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 Base Engineer testing returned equipment in a shoreside workshop. H2Flow replaces fragmented spreadsheets, legacy desktop software, and disconnected tools with a single, modern platform accessible from any browser or tablet.
Every workflow reflects how offshore operations actually run — not how a product manager imagines they should. From the 14-stage fault lifecycle to the pre-mob verification gate, every feature exists because someone needed it on a vessel.
You land on exactly what needs your attention today. The full system is one deliberate click away — not buried in menus. Batch operations mean crew changes that took an hour take five minutes.
Competency frameworks built around IMCA C001–C005 from day one. Maintenance management aligned to ISO 55001:2024. Container tracking supports DNV 2.7-1/2.7-2/2.7-3 and CSC certification requirements.
Ask the Bosun anything in plain language. No filters, no navigation required — the AI interrogates every module in parallel and surfaces the answer.
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.
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 between locations, its maintenance schedules automatically suspend and reinstate with recalculated due dates. Client audits go from stressful to straightforward.
Stop chasing paper packing lists. Scan a flight case or pallet box, assign it as a temporary location, then scan every asset you put inside. H2Flow generates a full contents manifest automatically — ship it with confidence and unpack at the destination by scanning the same code.
Map every component in a survey spread, ROV system, or towed array — visually. Upload a photo, drop numbered pins on each part, drill down into sub-assemblies. Build templates once, clone them across the fleet. Each vessel fills the slots with their specific kit.
Define operational modes — the equipment profile a vessel needs to run a specific job. Assign category-based requirements, link configuration trees, and check readiness against any vessel in real time. Red slots show what's missing. Fleet view shows where to source it.
Surveyors, engineers, divers, and ROV crews each land in a curated environment built around their actual job — not a generic menu. The Surveyor’s Log, Engineer’s Toolbox, Diving Bell, and ROV Shack bring together VLAN network management, cable diagrams, fault logging, and PMS tasks exactly where each team needs them.
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.
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 the cracks during a back-to-back crew change.
Built from the ground up for the realities of offshore operations — satellite connectivity, multi-vessel fleets, and mandatory regulatory compliance.
Ask H2Flow anything in plain language. Find assets with expiring certs, pull overdue maintenance across the fleet, or check crew availability — no filters, no navigation. Just ask.
Role-aware command centre. Every user — Survey Engineer, Asset Manager, Crewing Manager, Party Chief, Base Engineer — lands on exactly what demands their attention today. Faults, overdue maintenance, expiring certs, pending verifications, travel tasks — all scoped to their role and location.
Bird's-eye view of your entire fleet with live status dashboards. Drill into any vessel for a full picture of its assets, documents, crew, and maintenance status.
Every offshore discipline gets a curated environment built around their actual job. The Surveyor's Log, Engineer's Toolbox, Diving Bell, and ROV Shack each surface the tools that team actually uses — network management, cable diagrams, configuration trees, maintenance tasks, and fault logging — without the noise of everything else.
VLAN-organised IP management purpose-built for survey vessels. Hierarchical tree view of VLANs, subnets, and devices. Visual /24 subnet grid showing every IP address at a glance — assigned, free, gateway, and conflicts highlighted instantly. Full CRUD with conflict detection and utilisation bars per subnet.
Vessel-scoped operational management — POB tracking with shift breakdown, cabin allocation with shift-based cabin sharing, station-based muster lists, day/night shift management, crew transfer validation with batch confirmation, visitor log, and travel requests.
Operations base personnel get their own Focus page showing pending equipment verifications, fault investigations, storage maintenance due, and incoming transfers — scoped to their base location.
Day and night shift patterns (6-6, 12-12, custom) with two or three-column roster. Assign crew to shifts, swap all with one click, auto-split unassigned crew. Hot-bunk cabin sharing and shift-filtered muster lists.
Browser-based camera scanning across the entire platform. Scan an asset to view documents, raise a transfer, report a fault, or log maintenance. Scan a flight case to pack assets into it. Scan a shelf to place equipment. Print labels in Code 128 or QR format. No specialist hardware required — any phone or tablet.
Responsive layout with hamburger menu navigation, full-screen modals, and touch-friendly tables on phones and tablets. The scanner works on any device with a camera and HTTPS. Desktop experience unchanged.
Centralised documentation and reference material. Network maps, cable diagrams, procedures, and training resources — searchable and version-controlled.
Append-only audit trail for all data access and modifications. Every change, every transfer, every access — recorded and verifiable for client inspections and regulatory review.
Strictly isolated data per company via PostgreSQL Row-Level Security. Vessel-scoped access for Party Chiefs and Survey Teams, base-scoped access for Base Engineers, fleet-wide access for Asset Managers. Shared role accounts for vessel positions with editable name fields for auditability across crew rotations.
Fully customisable to match your company identity. Upload your logo, set your brand colours, and apply custom sidebar gradients — all through a built-in theme designer. Every PDF report, dashboard, and notification carries your branding. Multiple tenants, each with their own look and feel.
Generate branded PDF and Excel reports for audits, clients, and management — asset registers, maintenance history, PM compliance, fault registers, vessel readiness summaries, and certificate expiry reports. One click, one download. Tenant-branded cover pages with your logo and colours.
Every role sees only what they need. Crewing Managers access CMS, Asset Managers access AMS and PMS, Party Chiefs access PCT — all enforced at module level. No clutter, no confusion, no accidental access to data outside your department.
Browse calibration certificates, survey records and compliance documents by vessel or base. Tree view by category and asset, flat list with search, and gap report highlighting assets that should carry certification but don't.

The offshore survey industry has operational needs that no generic platform has ever addressed properly. H2Flow is building them — from the ground up, by someone who has worked the job.
Any offshore marine contracting company operating vessels, managing rotating crews, and maintaining survey or subsea equipment.
H2Flow is in active development. If you work in offshore survey or marine contracting and recognise the problems this platform solves, we want to hear from you. Early access partners help shape what gets built and in what order.
We've received your registration and will be in touch soon. We're excited to have you on board.
