The heritage is onshore pipeline engineering and Penspen has been involved in major pipeline projects around the world.  However, Penspen has expanded the range of services to meet clients’ needs, and Penspen now provides the full scope of engineering services for the life cycle of an asset. Penspen has also developed an extensive range of training services covering engineering design, integrity, and operations and maintenance, for energy assets.
