據7月10日Offshore Energy報道，意大利石油和天然氣公司埃尼已經向英國當局提交了其終止Hewett油田6個平臺的計劃。這些平臺中的5個(48/29A綜合體、48/29B和48/29C)位于UKCS 48/29區塊，其余平臺(52/5A)位于52/5區塊。

Hewett油田位于北海南部，諾福克海岸東北約22公里處。包括五個相互垂直的層位和六個相鄰的衛星場：Big Dotty、Little Dotty、Deborah、Dawn、Della和Delilah。

Hewett的主要油田：Big Dotty, Little Dotty和Deborah都在單一的聯合許可區域。Hewett油田的基礎設施包括6個平臺、32口平臺井和另外8口與平臺相連的海底井。

根據該計劃，所有六個平臺的上層甲板和護套將被拆除，并送回岸上進行處理、回收等。平臺退役活動最早開始于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.
