Petrodec 部署了其重型自升式作业船 Obana，在北海南部英国海域开展了首次商业退役作业，为 Perenco UK 的作业提供支持。

据 Perenco UK 的一份声明称，这艘被誉为“世界同类型最大的自升式重型起重平台”的船舶，在完成海上试验和准备工作后，已开始进行海上作业。

初期工作范围包括拆除加拉哈德平台（48/12a区块），涵盖其上部结构和导管架。随后，作业将转移至紫水晶油田，奥巴纳公司计划拆除多个导管架，包括C1D、A2D和B1D装置。

该项目标志着“奥巴纳”号正式投入运营，并显著提升了北海退役领域的重型起重能力。该船采用自升式平台，结合高容量起重能力，旨在执行复杂的拆除作业，从而实现单次起吊或减少起吊次数的拆除策略。

Perenco UK 正在开展这项工作，作为其在北海南部持续进行的退役计划的一部分，目标是其运营油田的后期基础设施。

Petrodec deployed its heavy lift jackup vessel Obana for its first commercial decommissioning campaign in the UK sector of the Southern North Sea, supporting operations for Perenco UK.

The vessel, described as the world’s largest self-elevating heavy lift jackup of its type, has started offshore work following completion of sea trials and readiness activities, according to a statement from Perenco UK.

The initial scope includes the removal of the Galahad platform (Block 48/12a), covering both topside and jacket structures. The campaign will then move to the Amethyst field, where Obana is scheduled to remove multiple jackets, including the C1D, A2D and B1D installations.

The project marks the start of Obana’s operational deployment and a significant addition to heavy lift capacity in the North Sea decommissioning sector. The vessel is designed to execute complex removal campaigns using a self-elevating platform combined with high-capacity lifting capabilities, enabling single-lift or reduced-lift removal strategies.

Perenco UK is conducting the work as part of its ongoing decommissioning program in the Southern North Sea, targeting late-life infrastructure across its operated fields.
