Abstract
The interruptive mobile production (IMP) system comprises a floating semisubmersible structure with equipment and facilities for hydrocarbon production in association with a small tension leg wellhead platform (TLWP) having direct vertical access. The small TLWP has an upper deck positioned above the surface of the water with wellhead equipment thereon and has risers generally vertically connecting subsea wells to the upper deck. Lateral bending restraints of the risers and tendons are preferably located at about the same horizontal level as the lower pontoon section. The semisubmersible structure can be conveniently disconnected from its moorings and from the wellhead platform for demobilizing to another location while the TLWP remains tethered in place.
