Ship Management Software: Build Custom or Buy SERTICA

What the off-the-shelf ship management products actually do well

Here is the recommendation before the reasoning: buy. If you technically manage a handful of vessels of similar type, a properly configured packaged system will do the job, and the money belongs in steel, coatings and spares rather than in a development budget.

SERTICA, BASSnet, ABS Nautical Systems, DNV ShipManager and Hanseaticsoft Cloud Fleet Manager are not thin products. They carry decades of maritime engineering in the parts that are genuinely hard: an equipment hierarchy running vessel, system, equipment, component and job; a job library shared across sister ships while allowing per vessel variation; running hours and calendar triggers; requisition through purchase order to receipt; and ship to shore replication designed for a satellite link that drops. Writing any one of those from scratch is a year you do not get back.

They also carry compliance scaffolding you would otherwise assemble yourself. Maintenance evidence for the International Safety Management (ISM) Code, certificate and class survey registers, Maritime Labour Convention 2006 record keeping, and reporting hooks for the International Maritime Organization Data Collection System and EU Monitoring, Reporting and Verification returns. None of that is a differentiator. It is table stakes, and buying it is correct.

They are strongest onboard. Chief engineers use these systems daily and vendors have iterated hardest there. If your problem is that a vessel has no maintenance system, or the one it has predates two class cycles, your answer is a product and a good implementation partner, not a bespoke build.

Where they stop: nobody assembles the inspection readiness judgement

Here is the workflow generic products model badly, and it is specific to your world. Whether a vessel would survive a port state control inspection tomorrow is a judgement built from six separate things: overdue critical maintenance, open defects on equipment covered by the safety management system, certificate and survey status against their windows, drill and training records, critical spare holdings, and the last internal audit. Every one of those sits in the system. None of them is joined.

Packaged systems report each domain well inside its own module, and that is not the same as a judgement. A superintendent covering eight ships cannot read six reports per vessel per week, so they substitute a relationship with the chief engineer, which works exactly as well as that individual relationship does. The failure mode is not negligence. It is that the officer boarding at 08:00 under the Paris Memorandum of Understanding or the Tokyo Memorandum of Understanding assembles the judgement in an hour, and you never did.

The second workflow they model badly is the survey window. Class regimes, including continuous machinery survey, define windows and credit conditions rather than expiry dates. A spreadsheet of expiry dates with conditional formatting answers when something lapses. It cannot answer which items could be credited opportunistically at a scheduled port call and which are heading for a deviation and a dedicated attendance. That question is worth real money every year and no product asks it for you.

The arithmetic: per vessel licensing against an amortised build

Do this with your own renewal invoice, not a vendor list price. Divide last year total licence and support by vessels covered. That is your per vessel annual cost. Add the fully loaded salary of the shore staff whose real job is moving data between the system and Excel, because that is part of the price of the product too.

Worked example with round numbers you should replace with yours. At $9,000 per vessel per year across ten vessels you pay $90,000 annually, or $450,000 across five years, before those analysts. A first release build at $180,000 with year two support at 18 percent runs roughly $310,000 over the same five years, and the curve flattens instead of tracking fleet growth.

The crossover here sits at about twelve to fifteen vessels for a single owner on one reporting format, and falls to eight or nine for a third party manager serving three or more owners, because each new owner adds reporting work rather than licences. Below eight vessels the arithmetic is not close, and any firm telling you otherwise is selling.

One caution on the per vessel figure. Several vendors price modules separately, so your renewal is not what you will pay once procurement, dry dock and crewing are switched on. Ask for the fully enabled price at your five year fleet plan before running the comparison. Ask separately what happens to the fee when a vessel is sold mid year and when one joins in month nine, because managers who grow by taking on ships in ones and twos discover that the pro rata rules are not symmetrical.

What a custom build actually costs, including the parts nobody quotes

In Digital Heroes delivery experience, a first release covering planned maintenance with evidence capture, a defect and deficiency register, requisition to purchase order and reliable ship to shore replication runs $110,000 to $250,000 in 16 to 24 weeks for a fleet of about ten vessels. A full platform adding survey and certificate planning, dry dock specification, budget against actual in multiple reporting structures, readiness scoring and crew handover runs $300,000 to $750,000 phased over 9 to 18 months.

Data migration is the line that surprises people. Budget 10 to 25 percent of the build for it. Your job library and equipment register hold years of accumulated knowledge about specific machinery on specific hulls, and it cannot be dumped and reloaded. Migrate one vessel class, verify it with the superintendent who owns those ships, then move on.

Year two is 15 to 20 percent of build cost annually. That covers hosting, support reachable during a dry dock rather than in office hours, and changes arriving from outside: a class society altering a survey code, an EU Emissions Trading System phase-in step changing what you surrender, an accounting system changing a file format.

What pushes you to the top of the band at sea: the number of distinct vessel types rather than hulls, onboard deployment across time zones, and genuine offline conflict resolution, which is engineering rather than a sync library.

The four situations where building wins

Regulatory fit is first. Carbon reporting under MARPOL Annex VI produces an annual Carbon Intensity Indicator rating of A to E per vessel, and the EU Emissions Trading System phases shipping in on a schedule that changes your obligation each year. If your charter parties allocate that cost between owner and charterer in wording specific to your contracts, no product models it and you reconcile in Excel forever. Tanker operators have the same problem with OCIMF vetting, where SIRE 2.0 turned an inspection report into a structured question set your system should be preparing against.

Scale economics is second, and the number is the one above: roughly twelve to fifteen vessels, sooner for third party managers.

Third is a workflow that is your competitive advantage. For a third party manager, owner reporting quality is the visible differentiator when every pitch sounds alike. Separating the transaction from the reporting structure, so one purchase rolls into your internal view, each owner budget format and a lender report without re-entry, wins management contracts. That is commercial value, not operational tidying.

Fourth is integration sprawl. Count your systems: planned maintenance, accounting, crewing and payroll, procurement or a supplier portal, noon reports and voyage data, and the class society portal. When three or more must agree and the agreement currently happens in a spreadsheet, you are already paying for a build in salary. Those spreadsheets are a specification somebody maintains at cost.

How to decide in a week

Run the readiness test on a Thursday. Pick three vessels, one of each type you operate. Give a superintendent thirty minutes per ship and one rule: produce the five items standing between that vessel and a clean inspection, ranked, with an owner and a date, without telephoning the ship.

Then count three things. How many of the five came from a single screen in your existing system. How many needed a second module joined by hand. How many needed a spreadsheet or a phone call. If two or fewer came from one screen, and a spreadsheet appeared for every vessel, the gap is structural and configuration will not close it.

Run the same test on the survey window question. Ask which class items in the next twelve months could be credited at a scheduled port call. If nobody answers without a naval architect and an afternoon, you have found the second build case.

Two more checks take an hour between them. Open the last three months of shore reporting that leadership actually reads and note how many of those files are Excel workbooks built from exports rather than screens in the system you pay for. Then ask your technical director which single question they wanted answered last quarter and could not get. Both answers point at the same layer, and it is almost never the onboard maintenance module.

Then buy the cheapest thing that settles the argument, which is a paid discovery phase. Digital Heroes writes a signed product requirements document before any code exists, covering the data model, the readiness rule set, permissions, integrations and acceptance criteria. You own that document. Take it to three other firms and you will get comparable quotes for the first time. We are the wrong firm if you want an implementation partner for an existing platform, or if you manage four ships and want talking into a build. We will tell you to configure what you have.
