An innovative floating LNG power station concept from South Korean shipbuilder Hyundai Heavy Industries (HHI) has been granted an approval in principle by class society Bureau Veritas (BV)
The AiP was for the Hyundai innovative Floating LNG to Power (Hi-FL2P) solution. The barge-based Hi-FL2P is described as an ‘all-in-one type’ FLNG power plant, incorporating all equipment and systems required for power generation and transmission including LNG containment, gas supply system and power plant. An AiP certificate was awarded to HHI chief technical officer Jae-Eul Kim by BV Korea country chief executive Christophe Capitant in a ceremony held in Ulsan, South Korea.
Developed under a joint development project between BV and HHI, Hi-FL2P will provide “significantly lower capex than land-based infrastructure and also supports the global demand for environmentally friendly power generation” said Mr Kim.
Mr Capitant commented “Bureau Veritas is very proud to have been actively involved in the development of this innovative concept of an all-in-one floating LNG power plant. The technical collaboration between Hyundai Heavy Industries and Bureau Veritas has been extremely fruitful and we are delighted it has led to such a positive outcome. The approval in principle granted to Hyundai Heavy Industries is the first milestone which hopefully paves the way for coming successes in the promising field of floating energy generation.”
With a length of 164 m, beam of 48 m, and depth of 28 m, Hi-FL2P will have three LNG storage tanks with a total capacity of 81,000 m3, and also comes equipped with 2,200 m3 of marine gas oil tanks. The unit generates power for its operation as well as for supplying to the land without a continuous external fuel supply facility such as a floating storage and regasification unit. To secure a competitive design for broader demands, HHI and BV carried out gap analysis against BV classification rules covering ‘Power Plant’, ‘FSU’, and ‘Winterisation’ based on HHI’s proven LNG carrier design.
The FLNG power plant will be a dual-fuel HHI HiMSEN 14H54DFV engine developed and manufactured by HHI’s Engine Machinery Division. Natural gas is used as the main fuel but in the case of an emergency it is also possible to use diesel oil for ships. By using the dual-fuel power generator, the overall operability would be maximised and the cost of an Hi-FL2P unit is significantly lower than that of using gas turbine generators.
On receiving a contract, the hull would be built in the shipbuilding division and the power plant manufactured at the engine machinery division and installed using an offshore crane with a 10,000 tonne lifting capacity.
