Connecting Fouling Insights with Cleaning Execution
CleanQuote and Vessel Performance Solutions partner up to help operators manage hull fouling
Aarhus, Denmark | Farum, Denmark | April 14, 2026
Hull fouling is one of those problems where the gap between knowing and doing is bigger than it should be.
Performance data that says a vessel is losing efficiency is useful. But it leaves the operator with a half-finished picture. They know something is wrong. They don’t always know whether it’s worth deviating to clean, which port actually has compliant options available, what those options cost, or how to quickly get quotes and make a decision. That gap — between the insight and the action — is where time gets wasted and money gets left on the table.
Today, we’re announcing a commercial partnership with Vessel Performance Solutions, a GTT Group company, to close that gap.
What VPS and VESPER do
Vessel Performance Solutions’ platform VESPER analyzes vessel performance data in real time. It tracks efficiency trends, flags early signs of hull and propeller fouling, and gives operators and performance managers a data-driven basis for deciding when underwater intervention is actually warranted — before it becomes a fuel penalty problem.
More than 40 customers trust VESPER to make these calls with confidence. That’s not a small thing. Most of the industry is still making fouling decisions based on gut feel, scheduled intervals, and whatever the last port agent said.
“Our goal with VESPER is to give operators precise clarity on when fouling begins to impact performance, well before it becomes a costly problem. This collaboration ensures VESPER is automatically kept up-to-date with the latest inspection and cleaning events, leading to well-timed, well-justified decisions about underwater intervention.”
Jakob Buus Petersen, Product Director for Performance at Vessel Performance Solutions.
What this means in practice
The cooperation brings the two platforms together in a way that reflects how the work actually flows.
For VESPER users: When fouling signals point toward intervention, operators can immediately access CleanQuote to evaluate their options — compliant cleaning methods, vetted suppliers, port-level regulations, and transparent pricing across 1,000+ ports worldwide. The decision doesn’t have to stop at “we should probably clean.” It can continue into “here’s where, here’s how, here’s what it costs, and here’s one button to click to get actual quotes.”
For CleanQuote users: When you’ve confirmed a cleaning, VESPER provides the before/after performance baseline that tells you what the cleaning actually achieved. That kind of data makes the next decision easier — and gives you something concrete to report upward.
The two platforms will also share data automatically. CleanQuote sends cleaning events and reports to VESPER, keeping the performance record current without any manual input from the operator.
Why this partnership exists
The match between CleanQuote and VESPER is. These two products solve adjacent problems, and each individually have no tools to solve the problem of the other. VESPER answers “when and whether.” CleanQuote answers “where, how, and at what cost.” Neither platform has tried to build what the other one does.
“Hull cleaning regulations are evolving rapidly across the globe, and CleanQuote’s role is to take away that complexity from fleet performance and operations teams. When operators arrive with clear performance data from VESPER, they can evaluate options faster and execute underwater cleaning with confidence.”
Mads Porsborg, Managing Director at CleanQuote
