I believe the problem is with the propane refrigeration circuit and not with the NLG production circuit. The plant however remains in non production mode until the fault is fixed.
That said one cannot compare the vastness of the Gorgon project and its problems to EGO's miniscule RG plant and the problems it experienced. But if one does compare, it is a matter of degree and comparative loss of revenue.
If EGO's brains trust deem RGN-1 commercial with a sustainable gas flow then I would hope they pay a hell of a lot more attention to the planning, building and commissioning of whatever extenstion is planned for the RG plant than the previous incompentant mob.
