据世界石油网站8月9日报道，根据最新数据显示，去年北海油气行业花费了16亿英镑(17.6亿美元)退役多余的油井和基础设施，这比过去五年的任何一年都要多。

根据最新的《北海过渡管理局(NSTA)退役成本和绩效报告》显示，从2017年到2022年，该行业总共花费了约80亿英镑(87.8亿美元)。

预计在未来十年，每年将有20亿英镑(22亿美元)用于退役，这是一个巨大的机会，可以继续发展该领域的技能和经验，并通过巩固其全球领导者的地位，帮助该供应链赢得海外利润丰厚的合同。

令人鼓舞的是，去年向NSTA提交的供应链行动计划(SCAP)中列出的英国北海退役项目中，约有70%的工作是由英国供应商负责的。

这表明该行业正在履行其北海过渡协议的承诺，确保至少一半的退役项目支出用于英国供应链，并履行其在油田停止生产后清洁和拆除基础设施的法律义务。

由于油气行业愿意分享经验和数据，并采用新技术和创新的商业模式，该行业在经济高效、安全的退役项目实施方面也取得了令人印象深刻的成绩。

然而，面对其他地区和行业(如海上风电)对设备、船舶和服务的需求增加等因素，实现进一步的改进将具有挑战性，这些因素推高了价格，使退役的总成本估计达到400亿英镑(439亿美元)。

NSTA相信行业能够克服这些困难，实现其成本效益目标，到2028年底将预算降至333亿英镑(365.5亿美元)。然而，运营商必须努力实现他们商定的时间表和承诺，与供应链更加协作，更早地分享他们的计划，确保资源在正确的时间可用。

NSTA正在通过引入新的关键绩效指标和基准来提供持续的支持，这些指标和基准是与行业共同开发的，并以新数据集的收集为基础，包括完成特定任务所需的时间长度、雇用的船员数量和使用的船舶类型。

新的指标将更全面地反映退役项目的计划和执行情况，帮助行业确定提高整体绩效和实现成本效益的机会。

NSTA: North sea O&G industry spent $1.76 billion on decommissioning in 2022, surpassing five-year record

The North Sea oil and gas industry spent ￡1.6 billion ($1.76 billion) decommissioning redundant wells and infrastructure last year, more than in any of the previous five years, new figures show.

The latest “North Sea Transition Authority (NSTA) Decommissioning Cost and Performance Report” reveals that the industry spent a total of around ￡8 billion (8.78 billion) from 2017-22.

And activity levels are expected to remain high, with about ￡2 billion ($2.2 billion) a year forecast to be spent on decommissioning in the next decade, a massive opportunity to keep developing skills and experience in the basin and help the supply chain win lucrative contracts overseas by reinforcing its status as global leader.

Encouragingly, UK suppliers are in line to secure around 70% of the work associated with UK North Sea decommissioning projects listed in Supply Chain Action Plans (SCAPs) lodged with the NSTA last year.

This indicates the sector is living up to its North Sea Transition Deal pledge to ensure at least half of spending on decommissioning projects goes to the UK supply chain, as well as meeting its legal obligation to clean and remove infrastructure once fields stop producing.

The industry has also built an impressive track record of carrying out decommissioning projects cost-efficiently and safely due to its willingness to share learnings and data – and embrace new technologies and innovative commercial models.

Achieving further improvements will be challenging, however, in the face of factors including heightened demand for equipment, vessels and services from other regions and sectors, such as offshore wind – which have pushed up prices, taking the total cost estimate for decommissioning to ￡40 billion ($43.9 billion).

The NSTA is confident that industry can overcome these hurdles and meet its cost-efficiency target – lowering the estimate to ￡33.3 billion ($36.55 billion) by end-2028. However, operators must strive to deliver their agreed schedules and commitments, work even more collaboratively with the supply chain and share their plans earlier, ensuring resources are available at the right time.

The NSTA is providing ongoing support by introducing new key performance indicators and benchmarks – developed with industry and underpinned by the collection of new datasets, including the length of time taken to complete specific tasks, the number of crew members employed, and the types of vessels used.

The new metrics will provide a more complete picture of how well decommissioning projects are being planned and executed, helping identify opportunities for industry to improve its overall performance and realise cost efficiencies.
