Shell's Prelude FLNG resumes operations after 4 months

After a lapse of four months, Shell‘s Prelude FLNG, the world’s largest floating liquefied natural gas facility (FLNG) offshore Western Australia, has finally restarted operations. On April 11, Shell issued an announcement saying that Prelude FLNG has resumed the delivery of LNG cargoes. “Our focus on Prelude FLNG remains to provide safe, continuous, and reliable performance in the long term.”

In December, Prelude FLNG was ordered shut down by NOPSEMA, Australia’s offshore oil and gas safety regulator, after a fire accident lost its main power source. This is the second time the Prelude FLNG has been forced to shut down since it started production. In March of this year, NOPSEMA announced the lifting of all regulatory restrictions on Shell’s restart of Prelude FLNG, although the restart time of Prelude FLNG was not determined at the time.

It is understood that Prelude FLNG, built by South Korea’s Samsung Heavy Industries, is the world’s largest floating offshore plant. The FLNG ship is 489 meters long, 74 meters wide, and has a displacement of about 600,000 tons. It was built with about 260,000 tons of steel and has more than 150 patents. Capable of producing 3.6 million tonnes of LNG, 1.3 million tonnes of condensate, and 400,000 tonnes of LPG annually, Prelude FLNG is designed to withstand once-in-a-century storms, enough to continue operations during the severe weather conditions of Australia’s tropical cyclone season.

Although the cost has never been announced, the industry speculates that the Prelude FLNG project cost more than 17 billion US dollars (about 113.849 billion yuan), even more than the USS Ford (about 13 billion US dollars). However, Prelude FLNG has experienced a series of safety and production issues since it set sail from South Korea’s Samsung Heavy Industries for its moorings off the coast of Australia in mid-2017. In fact, over the past four and a half years, Prelude FLNG has been in normal operation for less than 12 months.

Prelude FLNG shipped its first cargo in June 2019, two years behind schedule. But just over half a year later, Prelude FLNG was shut down in February 2020 due to a power failure. Prelude FLNG resumed production in January 2021 after a shutdown of up to 11 months. Prelude FLNG has been operating normally for most of 2021 until a fire in early December shut it down again.

It is understood that Prelude FLNG is located about 475 kilometers north-northeast of Broome, Western Australia. Shell owns 67.5% of the shares, and the remaining shares are owned by Japan International Petroleum Development Co., Ltd (17.5%), Kogas (10%) and Taiwan PetroChina (5%).

时隔四个月,壳牌壳牌位于西澳大利亚近海的全球最大浮式液化天然气装置(FLNG)Prelude FLNG终于重启运营。

4月11日,壳牌发布公告称,Prelude FLNG已经重新恢复了LNG货物的发运,“我们对Prelude FLNG的重点仍然是在未来长期提供安全、持续可靠的性能表现”。

去年12月,Prelude FLNG在发生火灾事故失去主电源后,被澳大利亚海上油气安全监管机构NOPSEMA下令关闭。这是Prelude FLNG投产以来第二次被迫关闭。今年3月,NOPSEMA宣布取消对壳牌重启Prelude FLNG的所有监管限制,不过当时Prelude FLNG并没有确定重启时间。

据了解,Prelude FLNG由韩国三星重工建造,是全球最大的浮式海工装置。这艘FLNG船长489米,型宽74米,排水量达约60万吨,建造时采用了大约26万吨钢材,具有超过150项专利。Prelude FLNG每年能够生产360万吨LNG、130万吨冷凝水和400000吨LPG,其设计可抵抗百年一遇的暴风雨,足以在澳大利亚热带气旋季恶劣的天气情况下继续运营。

虽然造价从未公布,但业界推测Prelude FLNG项目耗资超过了170亿美元(约合人民币1138.49亿元),甚至超过了美国海军福特号航空母舰(约130亿美元)。然而,自2017年年中从韩国三星重工起航前往澳大利亚沿海的系泊地点以来,Prelude FLNG就经历了一系列安全和生产问题。事实上,在过去的四年半时间里,Prelude FLNG正常工作的时间甚至不到12个月。

Prelude FLNG在2019年6月发运首批货物,比原计划推迟了两年。但仅仅在半年多后,Prelude FLNG就在2020年2月因电力故障而关闭。在停产长达11个月后,Prelude FLNG于2021年1月恢复生产。2021年大部分时间里,Prelude FLNG一直在正常运行,直到12月初发生火灾再度停产。

据了解,Prelude FLNG位于西澳大利亚布鲁姆东北偏北约475公里处,由壳牌拥有67.5%的股份,其余股份由日本国际石油开发株式会社(Inpex,17.5%)、韩国天然气公司(Kogas,10%)和台湾中油(5%)持有。
