Re: A job for Lewis
Thanks John but will give it a miss all the same. I have sailed on LNG and LPG with reliquafication plant on, bloody nightmare it is as well.
What the article does not say is they are also selling what are know as the Trader class LNG carriers as they are deemed to be to small now at 138.500 cubic metre liquid. Just for those who may not be familiar about LNG. 1 Cubic metre of liquidfied LNG remains as a liquid if the temperature is maintained at around -165 degrees centigrade, 1cubic metre generates 600 cubic metres of GAS.
An interesting article but to be honest BP are only playing at the LNG game , they are relitavely new comers to the market. Shell are one of the biggest players asis Ras Gas and the Quatarers.
read the article attached these Q max ships are massive compared to what others are operating, also these are mostly manned by British officers.
A ship of Q-Max size is 345 metres (1,132*ft) long and measures 53.8 metres (177*ft) wide and 34.7 metres (114*ft) high, with a draft of approximately 12 metres (39*ft).[9][10]
It has an LNG capacity of 266,000 cubic metres (9,400,000*cu*ft), equal to 161,994,000 cubic metres (5.7208×109*cu*ft) of natural gas. It is propelled by two slow speed diesel engines, which are claimed to be more efficient and environmentally friendly than traditional steam turbines.[11]
Q-Max vessels are equipped with an on-board re-liquefaction system to handle the boil-off gas, liquefy it and return the LNG to the cargo tanks.[12] The on-board re-liquefaction system allows a reduction of LNG losses, which produces economic and environmental benefits.
Overall, it is estimated that Q-Max carriers have about 40% lower energy requirements and carbon emissions than conventional LNG carriers.[13][14] The quoted estimates do however ignore the additional fuel used to re-liquify boil off gas rather than burn the gas for fuel. The ships can be converted to use the boil-off gas but as of February 2013 none have yet been converted.[citation needed]
Contractors[edit]
Q-Max LNG carriers were ordered in 2005.[9] They are to be built by Samsung Heavy Industries and Daewoo Shipbuilding & Marine Engineering.[9][13] The installed Boil Off Gas re-liquefaction system (Ecorel) is developed and delivered by Cryostar, and approved and certified by Lloyds Register.[15]
