Spare parts management in Bohai bay

Abstract

Spare parts management plays a critical part in the Oil and gas (O&G) industry. Traditional asset management could not meet the requirement of present equipment. Due to the complexity of inventory plus limitation of offshore platform, it is one complicated issue to accomplish effective and efficient inventory control for offshore operation. Having reasonable inventory is crucial for improving the continuous efficiency for spare parts and decreasing the maintenance budget, especially for the offshore operations.

Inventory analysis requires one criteria to optimize the spare parts stock. Most commonly used models for inventory are spare parts value-usage, criticality, frequency of demand. The combination of management policy and mathematical model is very complicated for the maintenance management. It needs too much mathematical knowledge and is not very efficient in spare parts analysis. Thus one classical model for analyzing the spare part demand is ABC model.

A specific example of platform in the Bohai Bay is used to demonstrate the spare parts management condition more specifically. Through systematic inventory analysis, unchangeable spare parts in the last five years account for high percentage. It is mainly composed of spare parts of turbine, compressor, and crane. After reorganization, spare parts on the platform are optimized and it saves much budget and space for platform.
