Boldrocchi Customizes a Cooling System for a Large Motor at the World’s First LNG Plant to use Combined-Cycle Technology

Products: Heat Exchangers & Coolers, Electrical Machine Cooling
Industry: Oil & Gas
Location: Darwin, Australia

Boldrocchi engineered and manufactured an air-to-water cooling system for a large motor at an LNG Project near Darwin, Australia. Boldrocchi designed & manufactured all parts of the cooling system with a power to dissipate of 600 Kw: the heat exchanger, tubes, fans, circulating pump & electrical devices. Our in-house facilities allowed us to undertake thermal, mechanical, structural, stress and noise tests, guaranteeing peak performance and reliability. This cooler was ASME VIII tested with a pressure 16 bar.

This cooler was designed to work at an air temperature of 10°C (50°F). It has double tube cooler elements and includes four centrifugal fans (ext) with installed power of 75 Kw each. It was engineered to provide 100% redundancy.

This project was an important one: it is the world’s first liquefied natural gas (LNG) plant to use combined cycle technology. The onshore plant is powered by natural gas from the Ichthys Field.
