HOUSTON – SPS will perform a no hot work structural steel reinstatement project onboard an FSO offshore southeast Malaysia this year, following approval by ABS.
The 841 sq m (9,052 sq ft) of main deck is said to be corroded beyond class limits and will be permanently reinstated.
A no hot work solution applies to plates or pipes exposed to volatile chemicals and involves application of structural adhesives and bolts to fix perimeter bars and top plates to the existing structure to form cavities.
The elastomer core is injected into these cavities, bonding to the top and bottom faceplates, thereby providing greater strength than the original structure.
Post-elastomer injection, the perimeter bars are structurally unnecessary, SPS said, adding that cavities are sized according to the existing structure: typically they are around 9 sq m (97 sq ft).
No hot work on the two-phase FSO project is due to take place between February and May, with the vessel remaining on station and fully operational throughout the campaign.
