挪威海上工业安全监管机构挪威海洋工业管理局 (Havtil) 已同意 Equinor 使用 Deepsea Bollsta 半潜式钻井平台在北海进行作业。

该钻机将用于位于北海北部、Gullfaks C 平台东北 10 公里处的 Visund Sór 油田的封堵、钻井和完井工作。

该区域水深290米。Visund Sør油田于2008年被发现，其开发和运营计划（PDO）于2011年获得批准。该油田采用与Gullfaks C油田配套的海底基盘进行开发。该油田于2012年开始生产。

Deepsea Bollsta 是 Moss CS60E 型半潜式钻井设施，由韩国现代重工造船厂 (HHI) 建造，于 2019 年竣工。

该钻井平台与 Equinor 签订了为期两年、价值 3.35 亿美元的合同，归海上钻井承包商 Northern Ocean 所有，并由 Odfjell Drilling 管理。

Norway’s offshore industry safety watchdog Norwegian Ocean Industry Authority (Havtil) has given Equinor consent to use the Deepsea Bollsta semi-submersible rig for operations in the North Sea.

The rig will be used for plugging, drilling and completion of wells on the Visund Sør field, located in the northern part of the North Sea, 10 kilometers northeast of the Gullfaks C platform.

The water depth in the area is 290 metres. Visund Sør was discovered in 2008, and the plan for development and operation (PDO) was approved in 2011. The field is developed with a subsea template tied to Gullfaks C. Production started in 2012.

Deepsea Bollsta is a semi-submersible drilling facility of the Moss CS60E type, built at the Hyundai Heavy Industries shipyard (HHI) in South Korea and completed in 2019.

The rig, under a two-year contract with Equinor valued at $335 million, is owned by offshore drilling contractor Northern Ocean and managed by Odfjell Drilling.
