EG55R1: PROCESS SHUT DOWN, STRUCTURAL DECOMMISSIONING & DISPOSAL (2020-2021)

Last modified: 22 Jul 2020 16:00


Course Overview

Decommissioning of oil and gas infrastructure is becoming a major issue for the North Sea and other mature basins.  This course provides students with an overview of the stages of shutting down the production process and cleaning of the system and then the possible methods of removal of the structure.

Course Description

This course presents the issues associated with decommissioning, dismantling and disposal of offshore structures and also process shut down and chemical disposal.  The decommissioning of upstream Oil & Gas processes is a staged process, with turndown and minimum operation options thoroughly explored before cessation of production. Once production is ceased, the isolation and cleaning of the plant and pipework can begin and brings its own challenges. The key aspects of process engineering for decommissioning are explored in this course.  Then comparison between abandonment (including so-called rigs to reefs) and offsite disposal is made.  An overview is presented of cutting, lifting and transportation technologies, for either piece small dismantling, heavy lift or single lift removal.  The issue of derogation for footings, and the particular difficulties of Gravity Base Structures, are explained.  The reuse and disposal of materials/equipment onshore is covered.
