The Soft Yoke Mooring System (SYMS) is part of the Bohai Phase I I development project, located in the Bohai Sea offthe north-east coast of the People’s Republic of China (PRC) approximately 140 miles from Tanggu and 85 miles fromDalian. The FPSO is permanently moored to a fixed tower. The transfer of all production fluids, power and control signals from the FPSO to/from the overall field development will be through this system.

The SYMS is fixed to the seabed by means of a jacket, supporting risers and J-tubes. The fixed deck facilitates the piglaunchers/receivers, drain tanks and control equipment.

The rotating deck transfers the mooring loads exerted by the yoke arms into the main bearing and allows 360o

rotational freedom up to the 100-year return storm. The rotating deck houses an offshore crane and the multiple product swivel stack including E & I and utility swivel. There are two hose connection decks: one on the rotating deckof the SYMS and one on the FPSO. The purpose of the decks is to support the jumper hoses and jumper cables whichcross-over from the rotating deck to the FPSO.

The pendulums and ballast blocks, located at the bottom end of the pendulums, are supported by the PendulumSupport Structure which is located on the forecastle deck of the FPSO. Two retractable bridges will give access fromthe FPSO to the rotating deck via the gangway on the yoke arms.
