(2) Survey and Basic plan
How does NOGAMI Corporation go about its maintenance planning?
First, NOGAMI Corporation collects pertinent information about plant facilities and functions to be guaranteed by its maintenance shop. In the case of a refinery, examples include:
- Maximum throughput
- Media for cooling
- Receiving voltage
- The scope of utility facilities such as water make-up facilities and power-generation units
- Facilities upstream and downstream
- Modern computer systems
- Control systems (e.g., digital control versus pneumatic control)
Details such as the above are generally sufficient for the first stage of basic planning of the maintenance shop, in combination with NOGAMI Corporation's in-house data on shop systems, investment costs, and so forth. Once the plan is formed, the plant owner will find the most efficient solution for investment in the maintenance shop.
The maintenance work is categorized as follows:
1. Daily maintenance work
2. Periodical maintenance work
3. Preventive maintenance work
4. Special maintenance work
Each step may be performed differently, by a different party. Step 1. above is usually performed by a maintenance team or troubleshooting team working in-house in the plant. The approach for steps 2 and 3 depends on the local condition. If a big shop is available, the work will be subcontracted. If not, facilities of an adequate type and scale to handle the maintenance will have to be installed. The approach for step 4 depends on the policy of the plant managers. Needless to say, unexpected troubles that cause long shutdowns and major damages are always a big headache. Long discussions with management are usually required to reach optimal solutions. The suggestions from NOGAMI Corporation at this stage often receive outstanding ratings from clients.
In the case of 'area maintenance shops' responsible for plural plants located in close proximity within specific areas, steps 2, 3, and 4 often have to be discussed at the same time. NOGAMI Corporation offers basic ideas for area maintenance based on the plant functions and features to be guaranteed.
Upon hearing NOGAMI Corporation's basic plans and suggestions, management discusses details with NOGAMI and forms a basic idea of the solutions in which it can invest.
