TDW Helps Relieve Stress on Riser Offshore Malaysia
T.D. Williamson (TDW) announced that it recently completed a comprehensive pipeline services program for a major offshore operator to assist with efforts to relieve increasing contact stress between a gas export riser and platform jacket offshore East Malaysia. Due to changes in seabed conditions, the platform jacket had moved, producing stress on the gas export riser attached to the platform jacket. The stress was most acute at the contact point between the bracings - or riser clamps - that anchor the riser to the platform structure.
Troll A Tie In Success for Pipeline Specialist STATS Group
Specialist engineering company, STATS Group, has completed an 18 month design, manufacturing and installation project to enable the tie-in of a fifth pipeline on Statoil’s Troll A Platform. Statoil’s Troll A platform, located off the west coast of Norway, utilises a system of seal tubes to tie-in risers which are run down the inside of a dry concrete leg. The seal tubes were concreted in place at the base of the riser leg on the gravity base structure in 1991. There are seven seal tubes – four designed for large bore pipe up to 36” - and three designed for smaller diameter pipe up to 20”.
TDW Offshore Completes Pipeline Pressure Isolation
TDW Offshore Services AS (TDW) has completed a key pipeline pressure isolation and joint testing operation offshore western Borneo in Malaysia for Sarawak Shell Berhad. TDW worked on platform F23P-A, which is part of the facilities operated by Sarawak Shell Berhad located 80 to 200 km from Miri and Bintulu. The operation was carried out on a gas export line that forms a portion of the line that runs from the F23P-A to the E11R-A platform. The network extends to one of the major trunklines connected to an LNG plant onshore in Bintulu.
