What Coach Is Worth: A Sample ROI Report

If you have to make the case for a hull or propeller cleaning to management, you need numbers that survive scrutiny. The figures below are averages drawn from a set of real customer ROI reports, each built from a customer's own validated data and reviewed with them by their performance manager. They are anonymized and expressed per vessel across a year, so you can scale them to your own fleet.

What the reports show

How the savings are calculated

The method is a like-for-like comparison. Using validated data and accurate fuel models, we compare what a vessel actually consumed after a hull cleaning against what it would have consumed had it kept sailing with a fouled hull and propeller. The benchmark is set at pre-cleaning performance, which is the conservative choice: in reality fouling keeps increasing, so the true gap is wider. What remains is the fuel that would have been wasted but wasn't, because the advisory normally catches the performance drop within 2 to 3 sailing days.

A word on the basis, so none of this reads as inflated. The per-vessel fuel and CO₂ figures come from one operator's year, a fleet of around 50 vessels in which nine were cleaned, each cleaning measured over only its first 30 sailing days, a deliberately short window. The time and emissions-reporting figures come from one chemical-tanker operator's full year: a fleet of around 36 vessels and 193 EU voyages, with each avoided voyage statement valued at the 215 USD a classification society such as DNV charges.

Beyond fuel

• •Around 145 hours of crew and shore time saved per vessel each year through Coach's semi-automated data validation, based on a chemical-tanker operator (reporting volumes vary by vessel type).
• •More than 20,000 noon reports validated across the year before anything reached a verifier.
• •Around $41,500 a year in EU emissions statements avoided, at the 215 USD per-voyage class-society rate.

Why it holds up

The numbers are conservative by construction, and each one is a full year that traces back to a validated, customer-signed report. The underlying mechanic is well understood by anyone who runs a fleet: a 1% loss of speed is roughly 3% more fuel, a vessel holding 95% of its speed is burning about 15% more than it should, and Coach flags the drift within two to three days of sailing rather than at the next dry dock.

What you get

Your own quarterly ROI report, built from your validated data, plus a monthly meeting where your performance manager walks through the numbers with you. The report is the proof; the people are the service.
