Fixed Structure Installation Aids

Oil States Barrow Temporary Pile Grippers (TPGs) provide a means for temporarily securing a template or jacket to its driven piles while permanent structural connections are made. TPGs are mounted at the top of a template’s pile sleeves or a jacket’s skirt-pile sleeves during fabrication. After foundation piles are driven, one or more TPGs are actuated to grip the pile, securing the structure while the leveling operation continues and the permanent connections are made. No diver intervention is required.

The high-strength, temporary connections provide the following important advantages during the installation process.

• TPGs facilitate the leveling process, because selected corners of the structure can be secured as leveling progresses, eliminating the need for multiple Latch-Lok™ tools and also improving grouting results
• The devices can be used to secure a jacket temporarily if weather forces the derrick barge off-location; total time required to secure a jacket is approximately 10 minutes
