Hydroniq Coolers has been commissioned to supply its patented Pleat seawater
cooling system for the cable installation vessel Nexans
The Pleat coolers will provide cooling of the vessel’s main engine and
auxiliary systems through the use of seawater. Hydroniq Coolers has not
disclosed the value of the contract.
currently under construction at Crist Shipyard in Poland and will be outfitted
for power cable laying, including bundle laying, cable jointing, repair,
cable system protection and trenching. Engineering, outfitting and system
integration, equipment preparations, testing, sea trials and finalising
will be carried out at Ulstein Verft, Norway.
It is to be equipped with dynamic positioning 3 and a 10,000 ton capacity,
split turntable. Its design is the result of a combination of input from
Nexans, Skipsteknisk, Ulstein Verft and MAATS Tech. It is to measure 31
metres wide, 149.9 metres long, with a deadweight of 17,000 tonnes, and
she will be capable of accommodating 90 people. The vessel scheduled to
be delivered in 2021.
Hydroniq Coolers will deliver its Pleat is a module-based titanium cooler
for seawater to freshwater, with design pressure six bars and design temperature
of 0-95°C. Marine cooling systems are utilised to reduce temperatures in
the ship’s engines and other auxiliary systems through use of seawater
to avoid overheating of the engine and other critical systems. Hydroniq
Coolers will manufacture at assemble the Pleat cooler at its headquarters
in Aalesund, Norway, and deliver it to Ulstein Verft in Ulsteinvik, Norway.
“Users of the Pleat benefits from long service intervals, which is an
advantage for vessels that operate offshore for long periods at a time.
Further, one crew member can easily maintain and clean the Pleat within
one hour, because compared to a traditional heat exchangers one Pleat cooling
element is equal to approximately 15 plates,” commented Hans Robert
Almestad, vice president of sales and marketing at Hydroniq Coolers.
