Penspen has been providing engineering, project management, asset management and integrity services to the energy industry worldwide for over 65+ years.  Originally founded in the UK in 1954 as Spencer & Partners, the company has now grown to include over 800 members of staff, with major offices in London, Mexico, Houston, Abu Dhabi and Bangkok.

During its history, Penspen has undertaken over 10,000 projects, addressing a wide range of challenges from the economic evaluation of pipelines to complex integrated facilities design.  Our heritage is onshore pipeline engineering and we have been involved in major pipeline projects around the world.  Our range of services has expanded to meet our clients’ needs and we now provide the full scope of engineering services for the lifecycle of an asset.

We have also developed an extensive range of training services covering engineering design, integrity, and operations and maintenance, for energy assets.

Penspen works with a wide range of clients including many well-known international and national oil companies, utilities and infrastructure owners.  We differentiate ourselves on the technical and operational quality of service which we deliver to our clients and partners.  Also, we have no ownership ties to operators, contractors or suppliers, and therefore provide a truly independent, best practice service.

Penspen is a proud member of the Dar Group.  The Dar Group is an international network of professional service firms, with over 18,000 staff in 59 countries.  It is dedicated to the engineering design and project management of major infrastructure projects. Penspen is able to draw upon the resources, expertise and experience of the entire Group.

Asset Integrity

We have been in the integrity business for 65+ years. Since then we have tackled a vast array of integrity problems and worked for and trained thousands of clients worldwide.

Asset integrity management is a formal process for protecting people, the environment and the operator from the consequences of asset failure. It also ensures compliance and optimises useful asset life. The central aspects of any Asset Integrity Management System (AIMS) are key performance indicators, risk assessment, organisation and competency. Software can be very useful and provide a level of comfort, but no single software product will ever provide everything an operator needs.

From pipelines and facilities to wells and structures, our services cover a broad range of asset integrity management requirements. The benefits of employing our services are a demonstrable minimisation of risk to people, the environment and the business, as well as optimisation of inspection, maintenance and asset life.
