Wison Gets LNG/Power Barge Approval
Chinese engineer Wison's Offshore & Marine business said September 19 its LNG regas/power plant barge design was 'approved in principle' by ship classification firm Lloyds Register.
Wison O&M said its 300MW Floating Storage Regasification and Power generation barge (FSRP) was developed to produce power starting as low as 7 US cents/kWh. With a total storage capacity of 170,000 m3 in GTT membrane cargo tanks, it can receive full cargoes, keeping the LNG supply costs low, and features a high efficiency CCGT power plant - available with an output of 150 to 450MW (see banner photo above, and below, courtesy of Wison/YouTube).
The facility is designed for near-shore deployment with a minimal water depth of 12 metres, said Wison O&M. LNG will be loaded through a ship-to-ship transfer and regasified, feeding the gas turbines. Waste heat from the turbines is recovered to generate steam, which in turn feeds the steam turbine generator. Electric power is stepped up to high voltage before transmission to shore.
Wison said a joint development project (JDP) agreement was signed September 19 between Lloyds Register, Wison and French LNG membrane technology firm GTT to develop work on the FSRP further. The Chinese engineer in July 2017 secured approval in principle from French classification firm Bureau Veritas for a prior 50 MW FSRP design; four months later it signed a memorandum of understanding on strategic co-operation regarding FSRPs with Shanghai Electric Power Generation Group.
Separately Wison agreed September 17 with Gazprom plans to work on expanding a petrochemical unit at Salavat, a city in the southern Russian republic of Bashkortostan. The agreement is to build a gas-to-polyolefin (ethylene and propene) project at subsidiary Gazprom Neftekhim Salavat’s existing 10mn metric tons/year refining and petrochemical complex in Salavat in Russia. Wison is to provide technical support to the project during the pre-feasibility study stage, offer support in project process design and process proposal selection, and do an economic feasibility analysis of the project.
