Radiators customized for engine cooling at Culzean in North Sea
Broadland Radiators has built two large radiators to help cool generator sets for Maersk Oil’s Culzean gas/condensate development in the UK central North Sea.
Dave Minshall, area sales manager for Eureka Pumps in Norway, which designed and supplied the packages, said: “The new radiators are used to cool technically complex, high specification emergency (EDG) and essential (ESG) generator sets designed specifically for the hostile North Sea environment.
“It was essential to use an experienced and flexible radiator supplier familiar with the strict requirements needed in…Culzean…”
The EDG package is powered by an AtEX rated (Zone 2) 12V4000P83 MTU engine with all ancillaries contained within an A60 container, measuring 8 x 5 x 4.9 m (26 x 16.4 x 16 ft).
To cool the equipment, Broadland designed and built a radiator measuring more than 4 m (13 ft) in width to fit within the offshore space restriction.
“Not only does the radiator enable the engine to operate efficiently at the highest potential ambient temperature of 24.5°C [76°F], it helps to dissipate the heat from the exhaust gas cooler,” explained Darrell Roper, the company’s general manager.
“Reducing the exhaust temperature to below 200°C [392°F] (Temperature Class T3) helps meet the requirements of AtEX 2014/34/EU.”
The ESG package was larger, measuring 9.8 x 5 x 5.3 m (32 x 16.4 x 17.4 ft) and featuring a 20V4000P83 MTU engine. Radiators on both units were manufactured from mild steel with the cores solder dipped to withstand the offshore environment: the finished coating is to NORSOK paint specification M501.
