Norway-based Hydroniq Coolers has been contracted by Wuhu Shipyard Co Ltd to deliver a hull-integrated seawater cooling systems to two LNG-fuelled oil product and chemical tankers the Chinese yard is building for Swedish tanker operator Donsötank.
Hydroniq’s Rack seawater cooler is integrated in the hull below the main engineroom of the vessel. Marine cooling systems help reduce temperatures in the ships’ engines and other auxiliary systems by using seawater.
Hydroniq Coolers will deliver both hull-integrated Rack seawater cooling systems by the end of Q2 this year. The construction and equipment of the two vessel newbuilds will follow the proven blueprints of Donsötank’s current oil products and chemical tankers, Prospero and Pacifico.
Hydroniq Coolers will manufacture the Rack seawater coolers at its Norwegian headquarters at Ellingsøy outside Ålesund and ship the systems to Wuhu Shipyard.
Wuhu will deliver both two dual-fuel 22,500-dwt oil and chemical tankers next year. The ships will have a cargo capacity of 27,800 m3, a length overal of 167 m and feature dual-fuel propulsion, shore power connection, and waste heat recovery systems.
“We will manufacture and deliver our Rack systems in less than three months, which is a quicker turnaround than we normally have. This is possible as the systems are copies of former systems we have delivered to Donsötank’s vessels,” said Hydroniq sales manager Jan Inge Johannesen.
The Rack system is designed to increase intervals between each clean and reduce cleaning time. Hydroniq said its product does not require drydocking for maintenance as the coolers can be extracted from below the engineroom, even while at sea.
The seawater cooling system will feature a dedicated chilled water bundle that allows seawater to bypass the chilled water unit and flow directly into the Rack cooler when the seawater temperature is below 14°C.
