Introduction  

I am the maintenance supervisor for a mechanical engineering service company called ‘Oil & Gas Europe’. I am responsible for the the organisation of all maintenance within the company’s business.

Currently all maintenance, service orders and reports have been recorded by a paper based maintenance system.

Our company has grown considerably over the last couple of years. The manager has approved that a Computer Maintenance Management System (CMMS) should be purchased and implemented throughout the company for all the maintenance operations.

I have been set the task of assessing different software packages and to recommend the one most suited for the company’s needs.

Description of Plant Operation

My company ‘Oil & Gas Europe’ is a subsea service company that focuses on providing drilling companies with in riser safety systems. These systems allow well operations to be conducted safely during drill stem testing (DST). They provide the ability to rapidly shut in the well and disconnect should conditions require it. ‘Oil & Gas Europe’ also provide EH landing strings. Electro-hydraulic control improves response times, enables ‘Real Time’ data feedback, reduces the physical umbilical size on deep water applications and addresses the disconnect philosophy from dynamically positioned mobile drilling units.  

Description of existing maintenance:

Currently ‘Oil & Gas Europe’ use a paper based maintenance system. Over the last couple of years ‘Oil & Gas Europe’ have grown rapidly meaning a paper based system is no longer suitable. This is inconvenient for the company because it makes documents hard to find and means documents can be easily damaged it also uses up a lot of storage area. We are looking into purchasing a CMMS because it will allow ease of traceability regarding maintenance within the company, reduce storage and also increase health and safety by removing a possible fire hazard of paper based documents.

Items to be maintained:

To test the CMMS programmes I have decided to create a maintenance programme for one of our electrical hydraulic control systems: Riser control module (RCM).

Below is a list of 22 items that need to be maintained within the RCM.

1. Mandrel

2. Crossover

3. Quick Connect Crossover

4. DCV

5. SOV

6. SEM Canister

7. Lower Mounting Sleeve

8. Upper Mounting Sleeve

9. Outer Cover (Lower)

10. Outer Cover (Upper)

11. Top Flange

12. Middle Flange

13. Lower Flange

14. PTTX Canister

15. Flow Meter

16. Flow Meter Canister

17. Bore Transducer

18. Shear Shuttle Assembly

19. Check Valve

20. DCV Manifold

21. SOV Manifold

22. Split Ring

Critical Path Analysis:

Critical Path Analysis is a project management technique used to lay out all activities needed to complete a task, the time it will take to complete activity and the link or relationship between activities. This method can help predict whether a project can be completed on time. CPA can be used to reorganise the project before it has started, but also allows reorganisation during the project as it progresses. CPA allows projects completion to be kept on track and ensures deliverables are ready on time.

CPA can be done manually or using computer software. The project manager makes a list of activities in the order they must be completed with time expectations, they then proceed to create diagrams of the process.

Health & Safety Considerations:

There are a few health and safety considerations relevant to our assets we must take into account when carrying out maintenance on components. It is also important to follow ‘Oil & Gas Europe’s’ maintenance document for the RCM which gives assembly/disassembly procedure details and any additional safety information/warnings.

Lifting Operations and Lifting Equipment Regulations (LOLER) must be considered during maintenance operations as many components are a considerable weight. LOLER includes duties of people and companies who own or have control over lifting equipment. This includes every business and organisations whose employees use lifting equipment, whether owned by them or not. In most cases lifting equipment is also work equipment so the Provision and Use of Work Equipment Regulations (PUWER) will also apply.  

Personal Protective Equipment Regulations (PPE) will also have to be considered when carrying out maintenance on RCM. PPE covers personal safety equipment such as high visibility fire retardant coveralls, safety boots, safety goggles and safety helmets.  

Control of Substances Hazardous to Health (COSHH) Regulations covers all substances that can be hazardous to health. In our RCM we have a sealed chamber filled Hydraulic Fluid and another sealed chamber filled with dielectric fluid these fluids would both fall under COSHH.
