Maintenance and Crew Compliance Software for Container Lines
Planned maintenance, spare parts, crew certificates, hours of rest and ISM, ISPS, MARPOL and ballast water records for feeder and regional container fleets.
Who this is for
- You own or manage container vessels, from a single feeder ship to a regional fleet
- Planned maintenance lives in spreadsheets, paper logs or an ageing on-board system
- Crew certificates and hours of rest are checked by hand before inspections and audits
- ISM, ISPS, MARPOL and ballast water records are spread across binders, folders and inboxes
- You want the office and every vessel to see the same maintenance and compliance picture
Container liner shipping runs to a schedule. Port stays are short, turnarounds are tight, and a machinery failure or a detention after a port state control inspection can cost a sailing. The technical and crewing side of a container line is under constant pressure, even though customers rarely see it.
SupaMaritime Merchant is software for that side of the business: planned maintenance tied to equipment and running hours, onboard inventory and spare parts, crew records with certificate expiry alerts, hours of rest checked against MLC and STCW limits, and ISM, ISPS, MARPOL and ballast water records, with a multi-vessel view for the office.
It is not a liner system. Bookings, stowage and bay planning, schedules, container equipment positioning, customs filings, slot-share arrangements and emissions reporting stay in the tools you already use. SupaMaritime does not connect to those tools; it covers maintenance, spare parts, crew and compliance.
Where the day breaks down
Maintenance squeezed into short port stays
Liner schedules leave little time alongside. Jobs slip from one port to the next when nobody can see what is overdue on each vessel.
Spare parts are not where the job needs them
Parts used on board are not written off, stock counts drift, and a critical spare turns out to be missing when the job comes up.
Crew certificates expire unnoticed
STCW certificates, medicals and endorsements for rotating crews are tracked in spreadsheets that are only as current as the last person who updated them.
Hours of rest under pressure
Night arrivals and back-to-back cargo operations push watchkeepers towards the MLC and STCW limits, and breaches are often found only at inspection.
Compliance records in too many places
ISM audits, ISPS drills, vessel certificates, MARPOL entries and ballast water records sit in separate binders, folders and email threads.
The office has no fleet-wide picture
Superintendents chase each vessel by email to find out what is overdue, what is expiring and which defects are still open.
Built around the workflow, not bolted on top
SupaMaritime Merchant brings maintenance, spare parts, crew and compliance records for every vessel into one web app. The crew on board and the office work on the same records, and the dashboard shows what needs attention across the fleet.
Planned maintenance and work orders
Maintenance jobs tied to equipment in the equipment register, scheduled by calendar or by running and engine hours. Work orders and defects are logged and followed up on the vessel record.
Onboard inventory and spare parts
Spare parts and stores per vessel. Parts used in a work order come off inventory, low stock shows on the dashboard, and inventory orders are raised from the same place.
Crew records and certificate alerts
Crew records with certificates and expiry alerts, a duty roster, timesheets and leave requests, so the office sees who is qualified and whose documents are about to lapse.
Hours of rest against MLC and STCW
Rest hours are recorded per crew member and checked against MLC and STCW limits, so a breach is visible when it happens rather than at the next inspection.
ISM, ISPS, MARPOL and ballast water records
A compliance hub for ISM and ISPS items, audits and drills, insurance inspections and vessel certificates with expiry reminders, plus MARPOL record entries (Annex I, IV, V and VI) and ballast water records.
Fleet dashboard for the office
Overdue maintenance, expiring documents, low stock and open defects across all vessels, with permissions by role and department.
Illustrative example: a regional feeder operator with three vessels
A hypothetical regional operator runs three feeder container vessels on a weekly service with short port stays. This is an illustrative scenario, not a customer story. Bookings, stowage and schedules stay in the operator’s existing systems; the example covers only the technical, crewing and compliance side.
Before SupaMaritime
After SupaMaritime
Each vessel keeps its own maintenance spreadsheet; the superintendent asks by email what is overdue.
Planned maintenance and work orders per vessel, scheduled by calendar or running hours, with overdue jobs on the dashboard.
Spare parts are counted once or twice a year, so the office never knows what is actually on board.
Parts used in work orders come off onboard inventory; low stock shows on the dashboard and inventory orders are raised in the app.
Crew certificates are scanned into a shared folder; expiry dates are checked by hand before each crew change.
Crew certificates are recorded against each crew member with expiry alerts.
Hours of rest are kept on paper sheets and reviewed only when an inspection is coming.
Hours of rest are recorded in the app and checked against MLC and STCW limits.
ISM, ISPS and vessel certificate records, MARPOL entries and ballast water records are spread across binders and inboxes.
ISM and ISPS items, audits, drills, vessel certificates, MARPOL entries and ballast water records sit in the compliance hub, with expiry reminders.

What SupaMaritime covers for a container line, and what it does not
A container line runs two kinds of software. The commercial and liner side handles bookings, documentation, stowage, schedules, equipment positioning, customs and partner agreements. The technical and crewing side keeps the ships maintained, crewed by qualified people and compliant with ISM, ISPS, MARPOL and the ballast water convention.
SupaMaritime Merchant covers only the second side: planned maintenance, spare parts, crew records, hours of rest and compliance records. It does not do stowage or bay planning, bookings, schedules, empty container repositioning, customs filings, voyage planning, fuel management or emissions reporting, and it has no connectors or public API to exchange data with the systems that do.
That makes it a fit for operators who want a clear, affordable tool for maintenance, crew and compliance next to their existing liner systems, rather than a replacement for them.
Planned maintenance around short port stays
On a liner schedule, maintenance that needs the vessel alongside or a machine stopped has to fit into short port windows. When the plan lives in separate spreadsheets per vessel, jobs slip quietly and the office finds out late.
In SupaMaritime, each maintenance job is tied to a piece of equipment in the equipment register and scheduled by calendar or by running and engine hours. Work orders record what was done, parts used come off onboard inventory, and defects stay open until they are closed. The dashboard lists overdue maintenance, open defects and low stock for every vessel.
The crew can also report through the Telegram assistant with messages, voice notes and photos, and an AI assistant answers questions from the manuals and documents you upload. The app runs in the browser on desktop, tablet and phone, and the last synced data stays readable when the signal drops.
Crew certificates and hours of rest on a liner schedule
Frequent port calls, night arrivals and cargo operations make rest hours one of the most common findings in inspections of container ships. At the same time, rotating crews mean a steady flow of certificates, medicals and endorsements to keep in date.
SupaMaritime keeps a record for each crew member with their certificates and expiry alerts, a duty roster, timesheets and leave requests. Hours of rest are recorded in the app and checked against MLC and STCW limits, so the master and the office can see a breach when it happens.
SupaMaritime does not run payroll or manning agency processes; it keeps the crew records, certificates and rest hours that inspections and audits look at.
ISM, ISPS, MARPOL and ballast water records in one place
Port state control officers and auditors ask for the same evidence on every visit: vessel certificates in date, ISM and ISPS records up to date, drills carried out, MARPOL and ballast water entries in order. Gathering that evidence from binders and inboxes takes time the crew does not have in port.
The SupaMaritime compliance hub holds ISM and ISPS items, audits and drills, insurance inspections and vessel certificates with expiry reminders. Merchant adds MARPOL record entries for Annex I, IV, V and VI and ballast water management records. Checklists, logbooks and documents with expiry reminders sit alongside.
SupaMaritime does not calculate or report emissions: CII, EEXI, EU ETS, FuelEU Maritime and MRV reporting stay with the tools and providers you use for them today.
How this compares to the alternatives
Established ship management suites covering technical management, crewing and QHSE for merchant fleets.
Logistics and freight-forwarding software for bookings, documentation and customs. A different job from SupaMaritime, which does not integrate with it.
Loading computer and stowage planning software used on container vessels. Stowage is outside the scope of SupaMaritime.
A common way to keep maintenance, crew and certificate records in smaller fleets. SupaMaritime replaces them for those records.
