Jumbo Installs MEG Riser on Ikhwezi, South Africa

Jumbo completed the subsea installation of the replacement MEG riser for the Ikhwezi Project at the existing FA Platform, at the end on January 2015. 

The contract was awarded by PetroSA at the end of 2014, Jumbo informed.

Jumbo’s Fairplayer, a DP2 Heavy Lift Crane Vessel with 2 x 900 Te revolving deep-water mast cranes, executed the offshore installation.

The detailed scope of work for the riser installation included:

– All installation engineering;
– Mobilization to South Africa;
– Load-out of 3” flexible MEG riser and protection/stabilization mattresses (Cape Town);
– Pre-survey and preparations at FA Platform;
– Installation (J-tube pull-in), protection and stabilization of MEG riser at PetroSA’s FA Platform;
– “As built” post installation survey.

With last year’s successful installation of PetroSA’s subsea structures in the Ikhwezi field, Fairplayer used the same installation method called “From Quayside-to-Seabed” for the riser installation.

Manager of Commerce Offshore, Roddy Lafontaine commented: “Our return to South Africa is recognition of our earlier fast track success with the Ikhwezi subsea structures.  We thank PetroSA for its continued confidence in Jumbo and the opportunity given to expand our services with the installation of subsea flexible risers.”

Project Ikhwezi is Petro SA’s plan to prolong the life of the Mossgas Gas-To-Liquids plant near Mossel Bay by tapping into gas reserves of the F-O field. The F-O field, developed as a subsea tie-back, is located 40km south-east of the existing FA production platform off the south coast of South Africa.
