Our story

challenging the status quo

Working in a leadership position for a rig owner Douglas observed major shortcomings compromising the assets’ performance and crew safety.

He felt a duty to challenge the status quo to ensure real assurance was given. Most importantly protecting the safety of the crew, whilst improving the efficiency and environmental performance of the asset.

We have grown to a team of over 60 with offices in Aberdeen (HQ), Houston, Kuala Lumpur and Singapore. However, Douglas’ founding vision remains at the heart of what we do. Above all it is what drives us to apply our knowledge and experience to support the energy transition.

Whether applied to rigs used in Oil and Gas, Geothermal or CCUS, or WTIVs to build wind farms of the future, we are committed to ensuring these assets operate safely and efficiently with minimal environmental impact. In short our independent audits and inspections make this a reality.

But most importantly our independence ensures that you can rely on our impartiality and objectivity throughout the inspection process.

“I started the company to make a real difference within the industry, I’m extremely proud of what we have achieved since those early days and we continue to grow as a team.”

Douglas Hay, Managing Director

Technical excellence, diversity of ideas, leadership and team work are at the forefront of our approach.

Our management team each have decades worth of experience leading, investing in and developing our team of subject matter experts. Consequently, many of the team have been with the company for over 10 years and are incredibly passionate about what we do.

“We place an importance on selecting people who not only excel technically but can also build relationships and work collaboratively with the rig or vessel owner project team, shipyard personnel and end user. From our experience this ensures the most value is gained from our inspection for all project stakeholders.”

Austin Hay, Director

We believe in supporting our local communities and every year, we pick a charitable organisation to support through donations and volunteering.

ADC Energy Ltd - AberNecessities Charity 2021

AberNecessities are a local, non-profit charity with the aim of supporting underprivileged families in Aberdeen and Aberdeenshire. They work with families in need of support, identified to them through social workers, midwifes, health visitors, family support workers, community nurses and other charities who submit an application on behalf of the family.

Thanks to the City’s kindness and generosity the donation rooms are continuously being topped up.  Right now AberNecessities are accepting donations of nearly new clothing for children aged 4yrs – 18yrs and pre-loved maternity clothing.

They kindly ask that any clothing donations are freshly washed and marked in age groups where possible.

It’s most definitely heart breaking but we couldn’t support over 250 children a month without the kindness of people like yourself. Thank you so much for your offer to make a donation from your company and to support our work by promoting our charity and volunteering.
