What Our Clients Say
Trusted by shipowners, fleet managers, and port operators worldwide
"We cleaned our bulk carrier fleet with PeakForce and saw fuel consumption drop by 13% on the first voyage. The robot worked while we were loading cargo — zero disruption."
"The cavitation system removed years of calcified barnacles without touching our anti-fouling coating. In 6 hours, the hull was spotless. No divers, no risks."
"We've used PeakForce at three different ports, including Shanghai with almost zero visibility. Their turbid-water camera system is the only one that works in those conditions."
