据7月10日Offshore Energy报道，意大利石油和天然气公司埃尼已经向英国当局提交了其终止Hewett油田6个平台的计划。这些平台中的5个(48/29A综合体、48/29B和48/29C)位于UKCS 48/29区块，其余平台(52/5A)位于52/5区块。

Hewett油田位于北海南部，诺福克海岸东北约22公里处。包括五个相互垂直的层位和六个相邻的卫星场：Big Dotty、Little Dotty、Deborah、Dawn、Della和Delilah。

Hewett的主要油田：Big Dotty, Little Dotty和Deborah都在单一的联合许可区域。Hewett油田的基础设施包括6个平台、32口平台井和另外8口与平台相连的海底井。

根据该计划，所有六个平台的上层甲板和护套将被拆除，并送回岸上进行处理、回收等。平台退役活动最早开始于2021年底。

Eni hands in decommissioning plan for six North Sea platforms

Italian oil and gas company Eni has submitted its plans for decommissioning of six platforms on the Hewett field to the UK authorities.

The Hewett field is located in the Southern North Sea, about 22 km northeast of the Norfolk coast.

Five of the Hewett platforms (48/29A Complex, 48/29B and 48/29C) are located in UKCS Block 48/29, with the remaining platform (52/5A) located in Block 52/5.

The Hewett area contains the main Hewett field, consisting of five horizons vertically situated above each other, and six adjacent satellite fields: Big Dotty, Little Dotty, Deborah, Dawn, Della, and Delilah.

The main Hewett field, Big Dotty, Little Dotty, and Deborah are in a single unitised licence area.

The Hewett field infrastructure comprises six platforms, 32 platform wells, and a further eight subsea wells tied back to the platforms.

Under the plan, topsides and jackets for all six platforms will be removed and returned to shore for processing, recycling or disposal.

The earliest start date for decommissioning activities is in late 2021.
