A topside module is being lifted to its jacket.
Doha: RasGas Company Limited (RasGas) announced that the $10.3bn Barzan Gas Project’s four offshore platform topside modules, collectively weighing a total of 9,500 tonnes, have successfully and safely been installed. This marks more than 80 percent completion of the project’s offshore and onshore construction.
Lifting for all three wellhead topsides and the additional living quarters module from the transport vessel on to their respective jackets was completed by Hyundai Heavy Industries’ (HHI) subcontractor, Seaway Heavy Lifting, using its 5,000-tonne heavy lift crane vessel, the Oleg Strashnov. The installation process lasted almost two weeks and involved teams operating on shifts round-the-clock.
The offshore scope of the Barzan Gas Project includes the installation of three wellhead platforms, living quarters and two pipelines to deliver gas to a new onshore gas processing plant in Ras Laffan Industrial City.
“Completion of this offshore installation takes the country’s landmark energy project one step closer to completion. We now look forward to continuing this teamwork during the final offshore hook-up phase of the project. This entails connecting 30 development wells located 80km off the coast of Qatar to subsea pipelines which will take gas to shore in Ras Laffan,” said Nafez Bseiso, RasGas Chief Venture Officer, in a press release issued yesterday.
The three wellhead topsides, impressive in scale and each weighing more than 3,000 tonnes along with the 450-tonne additional living quarters module were transported some 6,000 nautical miles via sea, on a 20-day journey, from Ulsan in South Korea to Qatar’s North Field onboard a heavy lift transport vessel, measuring 43 metres in width and more than 180 metres in length.
Bseiso said: “While the Barzan Gas Project is a prime example of Qatar’s push for sustainable development, it is also a demonstration of RasGas’ commitment to high safety standards and operational excellence. Successfully and safely executing projects of the scale of Barzan requires organisation and teamwork.
“The team is effectively coordinating a multi-national workforce of more than 29,000 staff across a three square kilometer site, often in challenging conditions and working at a rate of over 1.5 million work-hours per week,” Bseiso added.
RasGas was appointed by shareholders, Qatar Petroleum and ExxonMobil, to manage the Barzan Gas Project. When the two trains are in operation, they are expected to supply approximately 1.4 billion standard cubic feet of sales gas per day (Bscfd).
As Qatar anticipates an increased demand for energy to fuel infrastructure projects over the next decade, the Barzan Gas Project has monumental significance for the country’s sustainable growth. Intended to fuel the country’s planned megaprojects, the Barzan gas processing trains will make RasGas one of the largest single gas processors in the world.
RasGas Company Limited (RasGas) is a Qatari joint stock company established in 2001 by Qatar Petroleum and ExxonMobil RasGas Inc. RasGas acts as the operating company for and on behalf of the owners of the liquefied natural gas (LNG) projects RL, RL (II) and RL3 (Project Owners).
