Recycling of a major Dutch gas field, L7

Fit-for-Purpose

The L7 field consists of ten production platforms in the Dutch sector of the North Sea. The total weight of these installations is around 17,500 metric tons. The recycling rate is 98 % of all materials. The method involves preparation for removal and lifting by selected, fit-for-purpose vessels from the local supply chain. Transportation to the purpose-built recycling facility for oil and gas infrastructure, the AF Environmental Base Vats in Norway, is also included.

 

Carbon capture study

The Dutch L7 field represents the beginning of the Dutch petroleum industry. The field, constructed between 1975 and 1989, consists of a ‘Central Complex’ and surrounding satellite platforms.

The scope also includes installation work and preparations for the redevelopment of infrastructure for future use in carbon capture and storage (CCS). This infrastructure will be part of a study on the industrialization of CCS in abandoned gas wells.
