Started working my way through “Ship to Shore Logistics”
In the section on the Mulberrys and Pluto you mention that the flexible pipe technology was used in the middle east
Spooled rigid pipe and flexible flowline technology has been used extensively in the UK North Sea, Norway and the Gulf of Mexico for the last 25+ years.
Flexible flowlines are produced by FlexiFrance/Coflexip/Technip (Le Trait), Wellstream (Newcastle) and NOV (formerly NKT) in Kalundborg in Denmark. This technology was derived from the subsea cable structure and is known as unbonded flexible flowline.
Flexi pipe can be laided from spools or from a carosel which can be deck mounted or within a ships hull. Some of the specialist lay vessels also lay subsea power and telecoms cables.
Rigid pipe is spool laid from ships carrying a “Conumdrum” type spool and there are spool bases in Evanton on the Cromarty Firth and at Leith for laying up, welding and spooling pipe onto these ships. Subsea7 and Technip both operate reel lay vessels – google “Seven Navica” and “ApacheII”. Other operators such as McDermotts and GSP have different configuration of lay vessels – both ship and barge based.
Pipe spooled goes up to 16″ diameter and the limit to the pipe carried is the all up weight of the drum plus pipe. The ships are equipped with a “ramp” that straightens the pipe and controls the lay tensions during the installation phase. Pipe can also be cut, recovered and joined by welding station on the ramp.
There is a small book on the PLUTO lines, I think published by a firm on the IoW. The development of the flexi lines post war have tended to have been kept as a commerical secret by the companies concerned. Certainly the earliest products came from Coflexip/Flexifrance so how the knowledge ended up here from UK companies involved in PLUTO isnt clear.
