Hydroniq Coolers has completed the five-year classification of its Rack seawater cooling system that is installed on board the NKT Victoria high voltage cable-laying vessel.
NKT has not experienced any problems with cooling of the main engine or other auxiliary systems during the five-year period.
“It is always reassuring to know that our technology has operated trouble-free for five years,” says Lars Elling Gloppholm, sales manager for aftermarket and services at Hydroniq Coolers.
The Rack seawater cooler has been designed to increase intervals between cleaning, However, the recommendation is to quickly clean the system monthly through use of compressed air. The coolers can easily be extracted from below the engine room even when the ship is at sea if more thorough cleaning is required.
The seawater cooling system, called “Rack”, has been supplied by Hydroniq Coolers. The Rack system is integrated in the hull below the deck of NKT Victoria’s main engine room. The system is utilised to prevent overheating of the ship's engine and other auxiliary systems on board.
When the vessel’s operator recently docked NKT Victoria at Ulstein Verft in Ulsteinvik, Norway, the yard extracted and transported the Rack seawater cooler the 55-kilometre journey to Hydroniq Coolers’ headquarters at Ellingsøy outside Ålesund.
Once in place in the company’s workshop, Hydroniq Coolers cleaned all 14 bundles properly, replaced all seals and bolts, and conducted some minor pipe replacement work.
“All such activities are a standard part of the maintenance programme we undertake in connection with five-year classifications of the Rack cooler. It was a quick job, and the Rack system was returned to Ulstein Verft well within the timeframe we had been given to complete the job,” adds Lars Elling Gloppholm.
NKT Victoria is one of the world's most advanced and fuel-efficient, cable-laying vessels owned by NKT, one of the leading high voltage cable manufacturers.
Hydroniq Coolers delivers marine cooling solutions to vessels that operate within offshore, shipping, cruise, passenger transport, fishery and fish farming.
