Maintenance Optimisation Strategy

Asset: Offshore Gas Platform

Project Objective: To conduct a review of the Computerised Maintenance Management System (CMMS), and deliver recommendations that will improve the maintenance burden by implementing these changes through a series of maintenance optimisation techniques.

Location: UK

This scope of work focused around the content, structure and applied maintenance which was benchmarked against typical industry standards as well as ABL experience with similar assets, with the intent to identify opportunities for optimization. The review covered:

  • The structure and content of the functional location hierarchy
  • Frequency of the PM’s
  • Duration of PM’s
  • PM description and work instructions

Challenges faced by the client

  • Extreme over expenditure of maintenance budget
  • Not enough resources to liquidate the maintenance work orders
  • Inability to showcase an auditable maintenance history to HSE

What we did

  • Data collection and review
  • Workshop to agree key assumptions with the asset stakeholders
  • CMMS Gap Analysis
  • Planned Maintenance Benchmarking Study
  • Delivery of results and prioritised implementation plan based on risk, return on investment and criticality

Initial Findings


60% of criticality scoring was wrong, making it difficult to apply the correct level of maintenance

25 class codes were missing a maintenance strategy

65% of tags had no equipment types allocated, making it difficult to document corrective work at the correct level

Benefits and deliverables

  • Over $1,791,800 of annual planned maintenance savings by optimizing the frequency of existing maintenance activities and duration of tasks to clarify tool time durations
  • 50% of the man hour savings were derived from optimization of the asset were derived from optimization of the assets “lifting systems” planned maintenance
  • Associated cost savings were provided through the scope of work, as well as a reduction in the risk of safety related incidents by reducing the number of personnel required offshore per year
  • Reduced workload burden by implementing the ability to group, package and nest maintenance
  • Based on ABL’s experience, the allocated man hours/ tool time assigned to PM work orders were externally excessive causing an unrealistic burden on both man power and ability to schedule work
