HMC Completes Flowline, Riser Installation at BP Atlantis Project

On Sunday September 2, 2007, the P3 flow line was landed in its receptacle porch on the Atlantis PQ (Production Quarters). This followed the handover of the P3 steel catenary riser (SCR) from HMC's Balder to the PQ chain jack.

By reaching this milestone the Balder completed the extensive flowlines and risers installation program which started back in April 2006. The installation of the six in-field Atlantis lines has been a tremendous challenge.

HMC Project Manager Wendell Freeman said: "The Atlantis Pipe-in-Pipe (PiP) Flowline Project (AtFL) was the most challenging project I have worked on. The work was planned, engineered, and executed to the last detail; notwithstanding, there were setbacks and unforeseen problems. The best known problem was the Balder flooding incident. As disruptive as the incident was, the recovery of the Balder, in record time while continuing to perform installation activities, shows the character of HMC both onshore and offshore. The success of the Atlantis Flowline project and the groundwork it laid for future projects was a result of the close working corporation between HMC and BP and both parties' commitment to safety, quality, production, and attention to details. The offshore success started with a solid onshore foundation and was followed up by outstanding execution by the Balder, HMC PQ Crew, Union Manta and HMC PMT (Project Management Team). It was a job well done by all involved and it was my privilege to have been a part of the Atlantis Flowline Team."

Project Manager Bas Zoon added that "since this was HMC's first Pipe-in-Pipe job, a lot of new equipment had to be designed and fabricated. Three years of study and engineering and onshore fabrication were required to prepare all equipment and procedures and complete all tests, to be able to install the 16 by 10 inch PiP system in over 2000 meters of water depth. Most systems on board were loaded to their maximum capacity during installation of these heavy pipelines, especially during the transfer of the riser system to the platform. I am deeply impressed by the skill and team work that were displayed by the onshore preparation team and the offshore installation crews on DCV (Deepwater Construction Vessel) Balder, support vessels and platform in performing this work."

All Atlantis subsea activities have been completed and the Balder has moved on to it's next project.
