Enhancement of  the Life Extension Management Process for ageing Offshore Platforms on the Dutch Continental Shelf

This research is executed on behalf of State Supervision of Mines (SSM) established at the Haque-Leidscheveen, the Netherlands.
 
State Supervision of Mines (SSM) is an executive agency of the Dutch Ministry of Economic Affairs, Agriculture and Innovation(EL&I). SSM has several core tasks i.e. supervising compliance with relevant legislation connected with the detection and extraction of minerals and geo-thermal energy. Besides the core tasks of SSM include supervision of storage of substances and supervising compliance with the Gas Act in the field of safety of gas transport networks and making recommendations to the Minister of EL&I. SSM is responsible for the supervision and enforcement of all mining activities. Focused on safety (occupational & process / asset integrity), health, environment and optimal use of mineral resources within the Netherlands (onshore) as well as on the Dutch Continental Shelf (offshore). The minerals which are mined are mainly natural gas, crude oil and salt.

The mission statement of SSM, reflects these responsibilities:

“To ensure that the exploration and production of minerals is carried out in a responsible and socially acceptable manner”.

The focus of this thesis will be on the management of the Life Extension process, of the ageing gas production facilities on the Dutch Continental shelf. The result will be a guideline, which will lead to a higher level of control for the upcoming Life Extensions of these facilities. This guideline will be an synthesis of applied Life Cycle Management, Dutch Acts and ISO or API guidelines, which have enumerate, the industry’s best practice. The guideline will be applicable to SSM, operators/asset owners, Independent Experts and the industry related companies.

Many offshore production facilities in the Dutch sector of the North Sea are now reaching or have exceeded their original anticipated design life. The industry is dealing with this in an opaque manner. Therefore this research is aiming to find a way to achieve sustainable asset integrity during the Extended Life of the facility by formulating a guideline which will secure the total integrity of the facility by the management of the offshore operators, to ascertain their adequacy in managing ageing structures,

In this context the main research question is stated as:

How to get better grip on the Life Extension Management Process, of the Dutch Offshore Production Facilities?

Providing the required products and services on schedule will require well-tuned management activities for the whole Life Extended period. In this context these activities on high level are:

• a well-managed LEM process;
• defining and executing LEM in a structured way;
• defining the system performance for the Extended Life;
• clear, open and transparent communication.

Performing these activities requires well-equipped and competent actors in a well structured environment. To equip these actors a range of resources are essential, such as competent personnel, infrastructure, material, tools, etc.

Based on the activities described above the elements of the logistic process are renamed and redefined in line with the LEM guideline specifications determined in this research on a structured and logical way.

Which have lead to the development of a:

1. Process Diagram by structuring the LEM phases;
2. LEM System Model;
3. LEM communication platform.
