About Us

TEMS International – independent services that optimise drilling performance and ensure environmental compliance

About TEMS International

TEMS International is an independent oil and gas service company focused on delivering environmental services onboard drilling installations around the world. This includes ensuring environmental compliance, managing and optimising drilling performance systems, project managing a rig’s complete drilling waste management programme, and providing environmental rig and vessel audits.

Established in 2017, TEMS International was founded by Bill Walkingshaw, building on three decades of oil and gas industry experience and our skilled team has been helping clients with waste management and environmental compliance for drilling installations across the globe.

Headquartered in Aberdeen with offices in Houston and Kuala Lumpur we provide fully comprehensive or ad hoc project support. Onshore and offshore, from drilling performance analysis to environmental rig and vessel audits, our engineers tailor their advice for every project, grounded in an objective and robust analysis of your drilling location and an in-depth understanding of the region’s environmental legislation.

Unlike many of our competitors, we are completely independent of any product or equipment manufacturers, taking great pride in ensuring that our advice to clients is always impartial.

Wherever we work, our aim is simple: to provide unbiased advice and recommendations that optimise your operation, that exceeds environmental compliance legislation, dramatically reducing the carbon footprint of your drilling campaign and delivering significant cost savings – often greater than your investment in our services. The earlier we’re involved, the better.
