Danelec and CleanQuote Partner to Connect Vessel Performance Insights with Underwater Services Execution

Farum, Denmark, 14 April 2026: Danelec, a GTT Group company, has entered a commercial cooperation agreement with CleanQuote, a global platform for underwater inspection and hull cleaning services. The partnership will help ship operators move from identifying performance deterioration to executing well planned, compliant underwater services.

Central to the collaboration is VESPER, the decision support and benchmarking platform from Vessel Performance Solutions, a GTT Group company, trusted by 40+ customers. By analyzing vessel performance data in real time, VESPER highlights efficiency losses and early indications of hull or propeller fouling, giving operators a reliable basis for determining when action to improve performance should be considered.

“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.” says Jakob Buus Petersen, Product Director for Performance at Vessel Performance Solutions.

CleanQuote brings the operational dimension by helping operators plan and procure underwater inspections and cleanings. Its platform provides access to vetted underwater service providers across 1,000+ ports worldwide, consolidating port specific regulations, supplier capabilities, approved methods, and transparent pricing to help operators easily evaluate and select the best available options.

“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,” adds Mads Porsborg, Managing Director at CleanQuote.

This also highlights the growing integration within the GTT Group ecosystem, where in house expertise and external partnerships combine to offer seamless, end to end marine solutions. By extending its reach beyond data and analytics into operational execution and maintenance, GTT Group reinforces its position as a fully connected partner for the maritime industry.
