How We Repaired a Marine Ice Detection System the OEM Called Unrepairable
The Challenge
A vessel operating in icy waters experienced a failure in its Rutter Sigma S6 marine ice detection system — the radar-processing system the crew relies on to identify ice, icebergs, and small floating hazards such as growlers and bergy bits. With the system down, navigating safely through ice became significantly more difficult, and the vessel's margin for error at sea narrowed sharply. In these waters, ice detection is not a convenience — it is a core safety system.
When the OEM Said “Replace It”
The original equipment manufacturer inspected the failed unit and declared it unrepairable, recommending replacement of the complete ice detection system. A full replacement meant significant cost, long lead times, and extended downtime for a vessel that needed to be back in service. Rather than accept a scrap-and-replace verdict, the crew returned to port and shipped the failed unit to Flexa Systems for a second opinion and a true component-level evaluation.
Our Response
The moment the unit arrived, our engineers began a component-level repair — diagnosing the fault down to the board and component level instead of swapping out the whole system. Within 48 hours we located the failure, repaired the unit, and fully tested it in-house to confirm it was operating to specification. Just as important, we preserved the unit's original program and configuration — so nothing had to be reprogrammed, recalibrated, or recommissioned once it was back aboard.
The Result
The repaired unit was returned as a true plug-and-play solution: the crew reinstalled it, powered up, and the marine ice detection system was fully operational again, with its original program intact. The vessel avoided the cost and downtime of a complete system replacement and regained safe visibility of ice and icebergs ahead. What the OEM had written off as unrepairable, we brought back to full service in two days — proof that “replace the whole system” is often not the only option.
