0 Introduction
0.1 Scope and benefits of maintenance engineering
Maintenance engineering is a discipline applying competencies, methods, techniques and tools to develop
and support maintenance in order to ensure that an item is able to perform its required functions in a
safe, sustainable and cost-effective manner throughout the life cycle.
The prime aim of maintenance engineering is to contribute to the achievement of overall stakeholder
requirements through optimized and cost-effective maintenance as part of physical asset management.
The benefits of the contributions from maintenance engineering include, but are not limited to:
— achievement of dependability goals by influencing design;
— risk analysis related to maintenance;
— application of sustainability principles;
— achieved required integrity and safety level;
— achieved required performance and technical condition;
— improved life extension decisions;
— improved maintenance support performance;
— reduced environmental footprint by saving energy and raw materials consumption;
— improved competitiveness and output value.
0.2 Use of this document
This document is generic and provides guidance on the methodology to achieve maintenance engineering
aims.
The intended users of this document are personnel involved in design, procurement, construction,
commissioning, operation, improvement, maintenance and disposal/transition or decommissioning of
physical assets. No specific structure or size of organization is assumed so that maintenance engineering
effort should be tailored to suit specific applications and organisational requirements.
This document is based on the maintenance terminology as defined in EN 13306 Maintenance —
Maintenance terminology. Adjustments and additional terminology used, are found in Clause 3.
Clause 5 of this document describes maintenance engineering discipline and its objectives.
Clause 6 of this document describes maintenance engineering activities during the life cycle stages.
Activities are used to express the application of knowledge, skills and tools in maintenance engineering.
The following life cycle stages and substages are used, see 6.1:
1) concept stage with the following substages: feasibility and concept baseline;
2) development stage with the following substages: preliminary design and detailed design;
3) realization stage with the following substages: build and implementation / commissioning;
4) utilization stage with the following substage: operation and maintenance;
5) disposal/transition stage with the following substage: reuse,
