I liked jmw's idea of a horizontal tow and alternate option of lateral pull on the sub to disturb the sub settlement into the seabed material(unless this makes sub settle more into seabed!!)
Was wondering 52' length 8' Dia, 20'WD.
Wouldnt it help if only either end was to be lifted up first...
"Depending on the design and operating conditions, there are likely to be areas on an 'expansion loop' which have little movement and low stresses, and may be just as safe to tie in there as at another location. "
!! You sure not talking about the loop itself? Or are you really?

why would you use 31.8 for manifold?
I would use 31.3 for wall thickness and SIF's and use PD8010 for stress calculations.

For a 'pulled bend' you need some straight length at both the ends for the bending machine to get hold of the piece. In general this length is specified as 500mm, I believe.

odion,
Have you discussed this with your senior experienced colleagues?
Richard has stated the good direction for your problem. Now its upto you how you go for it. If I were you I would discuss in my work place in the first place.
Good luck.

Whatever the method you will adopt, we would appreciate if you can come up with the same with the results later.
Thanks in advance.

4 month on and still 5 months more to go. and this is estimate. At what stage of the design life is the pipeline? As BigInch has said already this is not going to be cost effective anyways.
Can the leaking bend be contained by two pigs from either sides? May be using some sort of rubber swell...
Hello all,
How about wood? the powdered wood may be split moulded to form a casing around pipe and this may be made rot proof over 20 years or so??
Just a idea.
