Topside Modules Complete for Liza Destiny

Total focus is now on the Liza Destiny FPSO at the Keppel shipyard in Singapore. The 12th  and final topside module was completed at Dyna-Mac and lifted onto the vessel in January 2019. See some of the highlights of the final topsides module lift campaign in this video.

In the first quarter of 2019, the team completed the lift and integration of the 120-meter flare tower, followed by the integration of the upper riser balcony, the riser gantry system, and the mooring porches and fair lead structures in the four corners of the FPSO hull.

With these large lifts complete, the profile of the FPSO is nearly finished pending the integration of the riser and umbilical pull-in system.

With the topsides modules installed, the team’s focus has turned to integration of the piping, electrical and control systems. As each system reaches mechanical completion, the construction and commissioning teams are working together to bring them online.

The commissioning team reached some key milestones in March by making minimum services available such as energizing low voltage switchgear, uninterrupted power supply (battery backup) and air compressor energization to make instrument air available to the topsides for instrument testing. They also achieved first flash ignition of the boilers in the vessel hull. The team is also working to energize all 1,560 lights that will illuminate the topsides facilities.

Another exciting commissioning milestone is the first crank of the gas turbine generators (GTGs). The engine was turned over on the starting gear after final alignments were complete to allow “first fire” of GTG1 on marine gas oil (MGO) fuel. When operational, the GTGs are capable of producing up to 120MW of electricity to run the process machinery.

The main deck cranes are now operational to allow additional material handling in support of final commissioning of the topsides. The FPSO remains on track to sail under its own power from Singapore later this year.

In preparation for the FPSO arrival in Guyana, the mooring systems (suction piles and chain-poly-chain mooring lines) are en route to a staging yard in Trinidad.

From here, the Normand Installer will mobilize to install the suction pile foundations and pre-tension the mooring lines in an arrangement that will allow them to be picked up and connected to the FPSO, later anchoring it to the sea floor offshore Guyana.
