J-Tubes Seals Delivered on the McDermott LTA-11 project

Following on from the Rasgas FAXP project Supergrip have now delivered 7-off Passive J-Tube Seals for McDermotts LTA-II project.

Multiple quantities of the following sizes were supplied:

– 118mm diameter umbilical to suit 12” NS J-Tube
– 130mm diameter umbilical to suit 12” NS J-Tube
– 145mm diameter umbilical to suit 12” NS J-Tube

All systems were the Supergrip dual resettable sealing system and were successfully pressure tested to 1.5 bar.g.

Sheldon Jeffrey, project manager at Supergrip, said “This project developed on from the successful FAXP project with similar J-Tube seal assemblies being supplied. The resettable nature of the design is advantageous during installation should the umbilical need pulling further through the J-Tube or indeed lowering due to over-pull of the cable during installation. The dual design of seals can both be de-energised and reactivated from the same end of the assembly making it an easy and efficient contingency measure”.
