Norwegian Techouse Awarded Contract for Waste Heat Steam Modules for Fourth Floating LNG Unit

en.Wedoany.com Reported - On November 10, Norwegian company Techouse was awarded an equipment subcontract by U.S. engineering firm Black & Veatch to supply two waste heat steam generation modules for Golar LNG's fourth floating LNG unit, with each module weighing approximately 1,000 tonnes, along with associated auxiliary operating systems. Equipment delivery is scheduled for completion by the end of 2028, and the integrated combined-cycle power system is expected to reduce fuel consumption by 20% to 25% compared with conventional gas turbine-only solutions.

The supply scope includes two waste heat steam generator modules and their associated systems. Techouse, as a subcontractor to Black & Veatch, is responsible for equipment engineering, procurement, and delivery, while Black & Veatch is responsible for the floating LNG unit's topside module solutions. Techouse will also participate in equipment installation and commissioning.

The two modules adopt a waste heat recovery scheme, utilizing exhaust heat from the gas turbines driving the natural gas liquefaction compressors to produce high-pressure superheated steam, which then drives a steam turbine to generate electricity and supply heat to the liquefaction process. The system converts part of the thermal energy from gas turbine exhaust into electricity and process heat, reducing the unit's additional fuel consumption. Techouse disclosed that with this scheme, the unit's fuel consumption is expected to be 20% to 25% lower than that of a gas turbine-only power system.

Equipment manufacturing will be carried out through collaboration among Norway, Vietnam, and China. Techouse is responsible for engineering design and procurement in Norway, and its partner Alpha ECC will manufacture the waste heat steam generator equipment in Vung Tau, Vietnam, after which it will be shipped to Himile Heavy Industries in China for module final assembly to form complete waste heat recovery modules. Project work has commenced, with equipment delivery scheduled for the end of 2028.

This is the first time Techouse has supplied complete waste heat steam generation modules to Black & Veatch and Golar LNG. Previously, the company had supplied waste heat recovery technology to Golar LNG's FLNG Gimi and FLNG Esperanza. This contract extends its supply scope from related technology equipment to complete modules and associated systems.
