Allseas Pioneering Spirit 号船通过一次无缝吊装作业，安全地将 15,300 吨的 Heather Alpha 上部结构从英国北海北部移走。
该作业于 8 月 11 日完工，标志着与运营商 EnQuest 和专业承包商合作完成的三年详细海上准备工作的结束。
希瑟阿尔法号位于阿伯丁东北460公里处，近50年来一直是北海的标志性建筑。它的拆除是“先锋精神”2025年行动中倒数第二次海上起重作业。
船体顶部结构采用船舶独特的运动补偿系统进行吊装，能够在几秒钟内拆除整个结构。这种方法最大限度地减少了海上作业的风险，减少了工时，并提高了安全性。
The Allseas Pioneering Spirit vessel safely removed the 15,300-ton Heather Alpha topsides from the UK northern North Sea in a single, seamless lift.
Completed on 11 August, the operation marked the culmination of three years of detailed offshore preparation, delivered in collaboration with operator EnQuest and specialist contractors.
Located 460 km northeast of Aberdeen, Heather Alpha has been a fixture of the North Sea for nearly 50 years. Its removal represents the penultimate offshore lift in Pioneering Spirit’s 2025 campaign.
The topsides was lifted using the vessel’s unique motion-compensated system, capable of removing entire structures in a matter of seconds. This method minimizes offshore exposure, reduces man-hours and enhances safety.
