The reality on site

The problems vessel & marine fleets keep running into.

Engine hours rule everything
Marine maintenance is hour-meter-driven from the main engine to the gensets to the gearbox — and most fleet platforms treat hour meters as a second-class citizen, bolted onto a vehicle-and-mileage worldview. The result is missed PMs and reports that don't add up at the end of the quarter.
Crew credentialing is a stack
USCG MMC, STCW endorsements, TWIC, drug-and-alcohol testing, recurring training — every crew member carries a folder of expiring credentials, and a single missed renewal can pull a vessel off charter the morning of a sailing.
USCG and class-society audits are demanding
Coast Guard inspections, ABS / DNV / Lloyd's class surveys, and customer audits all require records that hold up under scrutiny — immutable history, calculation-bearing fields, photos, PDFs. Spreadsheets and binders fail this test the first time an inspector opens them.
Connectivity is limited at sea
Mobile-first matters more in marine than almost any other industry — but so does offline capture. Engineers and deck crew need to log readings, photos, and inspections from the engine room or the deck without assuming Wi-Fi or LTE will be there to push the data immediately.
The FS365 difference

Five things vessel and marine fleets get with FS365.

Hour meters

Hour meters as a first-class citizen on every asset.

Main-engine hours, generator hours, gearbox hours — first-class on every vessel, with combined-meter scenarios supported. Schedule a 2,000-hour main-engine PM and a separate 500-hour genset oil change on the same vessel and Fleet Service 365 keeps each meter coherent. No more "due at 500" fields that could mean anything.

  • Per-meter due tracking on engines, gensets, gearboxes
  • Combined-meter PMs supported (twin engines, port + starboard)
  • Cost-per-hour reports an auditor can read

Operator renewals

Crew credentialing built for the marine stack.

USCG MMC, STCW endorsements, TWIC, drug-and-alcohol testing, recurring training — all in a first-class operator-renewals module, not stuffed into a custom field on a crew record. Configurable due-soon alerts in days, weeks, or months. A captain with an expired MMC is a vessel that doesn't sail — Fleet Service 365 makes sure that never surprises you.

  • USCG MMC, STCW, TWIC, drug-and-alcohol, recurring training
  • Configurable alerts in days, weeks, or months
  • One calendar across crews and vessels

Maintenance hierarchy

VMRS-grade maintenance hierarchies for marine.

Three-level codes for engines, generators, gearboxes, hulls, and deck equipment — the same depth commercial trucking and industrial fleets have used for decades, applied to vessels. Diagnose problems faster, build clean PM templates per vessel class, and pull cost-per-hour and cost-per-voyage reports that hold up in front of a customer or surveyor.

  • Three-level codes — Category › System › Assembly
  • PM templates by vessel class (workboat, tug, ferry)
  • Cost-per-hour and cost-per-voyage reports

Audits

Audit-ready by design — records that hold up.

Immutable calculation-bearing fields, full audit history on every record, photos and PDFs attached directly to assets, issues, and work orders. Export a clean record set for an ABS / DNV / Lloyd's class survey or a USCG inspection without scrambling the night before. Self-hosted deployment available on the Enterprise tier for operators with sovereignty requirements.

  • Immutable calculation-bearing fields
  • Full audit history with timestamps and authors
  • Self-hosted on Enterprise — air-gapped supported

Telematics

Our hardware. Your call on where to use it.

We build our own purpose-built FS365 marine trackers and AI bridge cameras — pair them with Fleet Service 365 where real-time visibility, geofencing, or recovery actually matters. Or run with no hardware at all and let crews capture engine-hour readings, photos, and inspections from a phone, with offline support for poor connectivity at sea. Mix and match across the fleet — never pay for telemetry on a barge that sits in the slip.

  • FS365 marine GPS, hardwired vessel telemetry, AI bridge cams
  • Offline-first mobile capture for engineers and deck crew
  • Mix hardware and manual vessels — no multi-year lock-in

Crew-tested details

Built for the way marine operators actually work.

A few of the things vessel and marine fleets tell us they actually use every week.

Multi-tenant for operators
Run multiple companies, divisions, or charter operations inside one Fleet Service 365 account — isolated data, shared admin, one bill.
Custom fields per vessel
Vessel class, IMO number, hailing port, route, charterer, operator — capture whatever your back office and class society need, without waiting on a feature request.
Multi-fuel: diesel, MGO, LNG
Track multiple fuel types per vessel and across the fleet — burn rates, bunker receipts, and consumption reports in one place.
Photos, PDFs & offline capture
Attach engine-room photos, survey PDFs, and bunker receipts directly to the vessel, the work order, or the issue. Offline-first mobile means crews capture now, sync when they have signal.
Open by design

Connect Claude or ChatGPT to your marine fleet.

Most marine EAM platforms are racing to build their own AI copilot — locked to one model, sold as a premium add-on. We took a different path. Fleet Service 365 ships a native MCP (Model Context Protocol) server, the open standard for connecting AI assistants to systems.

FAQ · Marine

Questions vessel operators ask first.

Yes. Hour meters are first-class on every asset, including main engines, generators, gearboxes, and deck equipment. Combined-meter scenarios — twin engines, port + starboard, parallel gensets — are supported, and PMs are scheduled per meter.
Yes. Every credential type is tracked in our first-class operator-renewals module — USCG MMC, STCW endorsements, TWIC, drug-and-alcohol testing, recurring training. Configurable due-soon alerts in days, weeks, or months.
Yes. The Enterprise tier supports on-premise deployment for marine operators with sovereignty or class-society requirements, including air-gapped environments.
Yes. Audit-ready by design — immutable calculation-bearing fields, full audit history with timestamps and authors, attached photos and PDFs, and full export support for ABS, DNV, Lloyd's, and USCG documentation.
No. Run with no hardware at all and capture readings, photos, and inspections from a phone with offline support. When real-time visibility matters, add our purpose-built FS365 marine GPS, hardwired vessel telemetry, or AI bridge cams on the vessels that need it. Mix freely across the fleet — never pay for telemetry on a barge that sits in the slip.
