據世界石油網站8月9日報道，根據最新數據顯示，去年北海油氣行業花費了16億英鎊(17.6億美元)退役多余的油井和基礎設施，這比過去五年的任何一年都要多。

根據最新的《北海過渡管理局(NSTA)退役成本和績效報告》顯示，從2017年到2022年，該行業總共花費了約80億英鎊(87.8億美元)。

預計在未來十年，每年將有20億英鎊(22億美元)用于退役，這是一個巨大的機會，可以繼續發展該領域的技能和經驗，并通過鞏固其全球領導者的地位，幫助該供應鏈贏得海外利潤豐厚的合同。

令人鼓舞的是，去年向NSTA提交的供應鏈行動計劃(SCAP)中列出的英國北海退役項目中，約有70%的工作是由英國供應商負責的。

這表明該行業正在履行其北海過渡協議的承諾，確保至少一半的退役項目支出用于英國供應鏈，并履行其在油田停止生產后清潔和拆除基礎設施的法律義務。

由于油氣行業愿意分享經驗和數據，并采用新技術和創新的商業模式，該行業在經濟高效、安全的退役項目實施方面也取得了令人印象深刻的成績。

然而，面對其他地區和行業(如海上風電)對設備、船舶和服務的需求增加等因素，實現進一步的改進將具有挑戰性，這些因素推高了價格，使退役的總成本估計達到400億英鎊(439億美元)。

NSTA相信行業能夠克服這些困難，實現其成本效益目標，到2028年底將預算降至333億英鎊(365.5億美元)。然而，運營商必須努力實現他們商定的時間表和承諾，與供應鏈更加協作，更早地分享他們的計劃，確保資源在正確的時間可用。

NSTA正在通過引入新的關鍵績效指標和基準來提供持續的支持，這些指標和基準是與行業共同開發的，并以新數據集的收集為基礎，包括完成特定任務所需的時間長度、雇用的船員數量和使用的船舶類型。

新的指標將更全面地反映退役項目的計劃和執行情況，幫助行業確定提高整體績效和實現成本效益的機會。

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.
