Inpex has let a contract to Hereema Marine to transport and install the 4,800-tonne LNG booster compression module at Ichthys gas field in the Browse basin offshore Western Australia.
The module is to be installed on the Ichthys Explorer central processing facility off the northwest coast.
The module will be transported from the McDermott fabrication yard on Batam Island, Indonesia to the field and then installed in a single lift using Hereema’s Sleipner semi-submersible crane vessel.
The vessel will perform both the transport and the lifting operations. It is capable of lifting 20,000 tonnes.
Ichthys field had an initial estimated reserve of 13 tcf of gas and over 500 million bbl of condensate.
The field came on stream in 2018 and has capacity to produce at a plateau rate of 8.9 million tonnes/year (mtpy) of LNG, 1.6 mtpy of LPG, and 100,000 b/d of condensate.
Gas is piped 890 km from the field to an LNG plant at Bladen Point in Darwin. Condensate is transferred to an FPSO at the field and sent to market via offtake tankers.
