Every day a vessel is off hire forfeits the full day rate, and the repair bill lands on top. Most of that downtime comes from a few major breakdowns, and the warning signs are usually already in your maintenance records. Enter your fleet by vessel class and see what they could be worth.
Pre-filled with a typical offshore support fleet. The defaults are general market ranges, not any operator’s records. Swap in your own vessel classes, day rates, and the off-hire days from your off-hire report.
Not every breakdown is avoidable. This decides how much of it is in play.
Failures written only in the notes, deferred jobs that came back as breakdowns, repeat failures on the same equipment. Our own model starts at 20 percent: about one lost day in five.
Over doing the same job planned: callout technicians, expedited parts and freight, extra port time. Set to 0 to count day rate only.
The same history shows which planned jobs find nothing when the equipment is opened up. Doing those less often, or dropping them, saves part of the PM spend you set for each class. Set this to 0 to leave it out.
Conservative: 3 to 8 percent.

a year across 24 vessels, from off-hire days avoided and planned maintenance saved. Low end counted at half.
Off hire costs this fleet about $4.8M a year today: 140 breakdown days.
$290K to $590K a year on this class alone. It is the biggest return among classes with at least 6 sister vessels, enough history to rank. Phase one covers one vessel class at a fixed price.
Close call with Platform supply vessels ($260K to $520K). The real pick comes down to which class has the deeper, cleaner maintenance history.
This is an estimate, not a finding. A fixed-price first phase replaces every assumption here with your own records: one export from your maintenance system and the off-hire report you already keep. It ends in a written go or no-go with a confidence figure.

Because that is where the money is. Under a standard offshore charter, no hire is paid for time lost to a machinery breakdown, so every day off hire forfeits the full day rate. A failure caught early can usually be fixed as planned work, between jobs, in port, or inside the maintenance time many charters allow, so it costs little or no hire. An hour saved by a crew on a fixed roster is not a dollar saved. A day back on hire is.
Downtime: off-hire days times day rate times the share of breakdowns whose warning signs are already in your records, plus the extra cost of an unplanned repair over doing the same job planned. Planned maintenance: what each class spends on it times the share saved by doing jobs that find nothing less often, or dropping them. The low end of the range counts both at half, the way we hold any unproven return low. The high end counts them in full.
It is the starting assumption in our own return model: stop about one lost day in five. For context, the US Department of Energy’s O&M Best Practices Guide reports predictive maintenance cutting downtime by 35 to 45 percent across general industry. Ships are not general industry, so we start well below that and let your records set the real figure.
No. The defaults are a typical offshore support fleet built from general market ranges, and day rates vary widely by region. No client’s records are used, in any form. Replace the defaults with your own and the math updates live. Your figures stay in your browser.
A fixed-price first phase on one vessel class replaces every assumption here with your own records: one export from TM Master or another planned-maintenance system, plus the off-hire report you already keep. It ends in a written go or no-go with a confidence figure.
