METHOD FOR INSTALLING A TIRED LEG PLATFORM (TLP) WITH EXTENSION SUB AND APPLIANCE TO APPLY A TRACTION FORCE

摘要

method for installing a tossed leg platform ("tlp") with extension sub and device. it is a self-tensioning tendon (10) to pull a tossed leg platform (tlp) (2) downwards to a desired draft position. the self-tensioning tendon (10) can be used both in an installation co-process and in an installation pre-process and connects to an assembled tendon joint, the self-tensioning tendon (10) comprises a joint length adjustment joint - slab (17) hydraulically controlled which additionally comprises an integral cylinder (18) with external threads and a piston rod (20). the self-tensioning device (10) has features that advantageously reduce the time required for ballasting the hull of tlp (2). a hydraulic source acts on the integral cylinder (18) to pull the tlp (2) downwards to the target draft position, significantly reducing the time required to ballast the hull of the tlp (2) with millions of gallons of water. a top tendon connector (top tendon conflector - uncle) (16) makes the downward ratchet movement along the cylinder (18) to lock the tlp (2) in the final draft position.
