Written Scheme of Examination

Written Scheme of Examination

Professional Written Scheme of Examination Services

A Written Scheme of Examination (WSE) is a documented inspection programme designed to ensure pressure systems and other safety-critical equipment are examined, maintained, and operated safely throughout their service life. It specifies the equipment that requires inspection, the examination methods to be used, and the frequency of inspections, helping organisations remain compliant with statutory regulations while protecting people, assets, and the environment.

Our experienced engineers develop comprehensive Written Schemes of Examination tailored to your pressure systems, operating conditions, and industry requirements. Each scheme is prepared in accordance with applicable legislation and recognised engineering standards, providing a clear framework for ongoing inspection, maintenance, and compliance management.

Whether your facility operates in the oil & gas, petrochemical, chemical processing, manufacturing, power generation, or industrial sectors, our WSE services help ensure your equipment continues to operate safely.

What is a Written Scheme of Examination?

A Written Scheme of Examination is a formal document that identifies pressure equipment requiring periodic examination and defines how those examinations should be carried out. It outlines inspection intervals, examination techniques, acceptance criteria, and any special safety precautions necessary to maintain the integrity of the system.

A properly prepared WSE forms the foundation of an effective inspection programme, helping organisations prevent equipment failures, reduce operational risks, and demonstrate compliance with pressure system safety regulations.

  • Preparation of bespoke Written Schemes of Examination (WSE)
  • Assessment of pressure systems and safety-critical equipment
  • Identification of pressure vessels, pipework, safety valves, and associated components requiring examination
  • Development of inspection schedules and examination intervals
  • Selection of appropriate inspection and testing methods
  • Compliance with applicable legislation and recognised industry standards
  • Technical documentation and certification support

Benefits of a Written Scheme of Examination

Regulatory Compliance

Our professionally prepared WSE documents help ensure your pressure systems meet legal obligations and comply with recognised industry standards, supporting regulatory inspections and audits.

Enhanced Safety

Clearly defined inspection procedures reduce the risk of equipment failure, helping to protect personnel, facilities, and the surrounding environment from potential hazards.

Proactive Risk Management

Regular examinations carried out in accordance with a WSE enable defects to be identified early, allowing corrective action before problems develop into costly failures or safety incidents.

Efficient Maintenance Planning

Defined inspection intervals allow maintenance activities to be planned in advance, reducing unexpected shutdowns and improving operational efficiency.

Comprehensive Documentation

A Written Scheme of Examination provides a complete record of inspection requirements, examination procedures, and maintenance obligations, making compliance easier to demonstrate.

Improved Asset Reliability

Routine inspections performed in accordance with a WSE help maintain equipment integrity, improve operational reliability, and extend the service life of pressure systems and associated equipment.

Our Written Scheme of Examination services provide a structured and compliant approach to managing pressure systems, helping your organisation improve safety, reduce risk, and maintain reliable operations throughout the lifecycle of your critical assets.
