OFFSHORE EXPERT: “Having read this Prelude document a few times to take it all in, it seems to me that the main issue is how do you design for a 10,000 year event?” COMMENT: “I am not an expert and would only say that so-called 10,000 year weather events seem to be occurring annually at the moment. If Noah was still around, and residing in Southern England, he might well be looking for his carpentry tools.”
COMMENT FROM A RETIRED SHELL OFFSHORE MANAGER
Regarding recent discussions on this website about Shell Prelude FLNG project, information available via this link provides useful input.
The 28 page section of a 75 page Shell document gives a description of the development and goes into great detail, providing answers to most of the issues raised by a fellow Shell Retiree.
Having read this Prelude document a few times to take it all in, it seems to me that the main issue is how do you design for a 10,000 year event?
The many issues raised with respect to cyclonic activity, waves, wind and the ability to weather vane are answered. There are two thrusters located near the stern with a total power of 6 megawatts or 8,000 HP. More than ample to ensure the heading of the facility is optimum at all times. Other issues with respect to Green house gas emissions during operations and other environmental are dealt with in detail.
