Outside shutdown :

– No hotwork = less risk, less people to do the job, less equipment to mobilise, quicker to complete the job
– Speed of operation (At least 90% quicker than welding)
– No Welding Procedure Qualifications
– Can operate without risk whilst facility is in operation, the alternative of shut-down is extremely costly.
– Can avoid pressurized habitats
– Keeps the work out of the shutdown plan
– Platform personnel can complete the work when it suits them

Inside shutdown :

– No hotwork = less risk, less people to do the job, less equipment to mobilise, quicker to complete the job
– Speed of operation (At least 90% quicker than welding)
– No Welding Procedure Qualifications
– Many more connections can be made using QF in the same time compared to welding, and with less personnel (More work in same or less time, by fewer people)
– Allows the welding people to concentrate on other work where there is no alternative to welding
– More efficient use of people – cross training offers chance to have multi-disciplined teams fitting QF – typically these would not be able to weld to the suitable standard
