How Eltherm Supports the Oil & Gas Industry
In the oil and gas industry, even the smallest drop in temperature can pose serious risks to safety, production efficiency, and profitability. Freezing of fluids, condensation, or temperature loss in pipelines and equipment can lead to flow interruptions, product degradation, or costly shutdowns. That’s why leading energy companies across the world trust Eltherm for cutting-edge electrical heat trace systems and heated hoses.
As a global specialist in trace heating technology, Eltherm supports operators in upstream, midstream, and downstream operations. Whether ensuring flow assurance in Arctic regions, maintaining critical temperatures in LNG applications, or providing frost protection in offshore installations, Eltherm solutions are engineered for maximum reliability, efficiency, and compliance.
With a presence in over 100 countries and a strong portfolio of references—including Shell, ADNOC, Petrofac, BP, Santos, ENI, and Bechtel—Eltherm has proven its ability to deliver bespoke heating systems for even the most complex and hazardous applications.
In this blog series, Thorne & Derrick highlight real-world case studies showcasing how Eltherm has helped solve operational challenges in the oil & gas sector.

The Puente Mayorga plant in Spain is one of the largest LAB production facilities worldwide. It uses UOP’s HF technology based on alkylation with hydrofluoric acid, and we produce normal paraffins, linear alkylbenzene (LAB), heavy alkylate (HAB), and sulfonic acid (LABSA).
In 2021, the Puente Mayorga plant undertook significant modernisation works, a key facility within their chemical production operations. As part of this upgrade, the team provided a comprehensive electric heat tracing system tailored to meet the performance, safety, and efficiency standards required by the site.

Thorne & Derrick International, a leading distributor of power systems, hazardous area equipment, and process heating solutions, is proud to celebrate its 40th anniversary this year.
Established in 1985 by Victor Thorne and Brian Derrick, the business started trading as Thorne & Derrick from premises in Brislington, Bristol. From the outset, the Company built a strong reputation, representing world-renowned manufacturers such as 3M Electrical, Band-It, and Cembre, supplying their market leading products to critical infrastructure projects and industries.
In 1988 expansion came with the acquisition of Reid Brothers (Glasgow), strengthening the Company’s presence in the strapping and load securing market.
A major milestone came in 1992, when Richard Derrick began operating in the Northeast of England working from a home office in Fenham, Newcastle. Initially Richard focused on selling Electrical Trace Heating solutions from Raychem, but after a move to Gear House in Gateshead, the Northern business expanded into the LV and HV power market. After 23 years, the office relocated to the current Northern headquarters at Lumley Court, Chester-le-Street which is the engine room of the company’s sales and marketing activity today.
In 2015, Reid Brothers was purchased from Thorne & Derrick International, in a management team buyout and is still thriving today.
Meanwhile, after 31 years in Brislington, Bristol, significant business growth forced a relocation in 2016 to Whitchurch, Bristol, where it continues to operate as the Company’s central warehouse and administration centre, coupled with a very strong Export and UK sales department.
Over four decades, Thorne & Derrick International has grown from its initial team of 6 to over 30 staff and from a first order of just £500 in August 1985, the Company is now on track to deliver over £20 million turnover in the very near future.
From the 1980s onwards, the Company has played an important role in serving the Oil & Gas, Process and Petrochemical sectors, and that has been central to its growth. As these markets continues to change, the business has expanded its product range in support, ensuring continued relevance and service excellence.
“As Managing Director, I’m incredibly proud of the team we’ve built over the years. Our strong focus on investing in young talent through apprenticeships has not only helped shape skilled professionals, but has also fostered a culture of loyalty and dedication,” said Richard Derrick. “It’s rewarding to see so many of our people grow with the Company. Their expertise and commitment are at the heart of our continued success.”
The team of technical sales engineers, sourcing specialists and customer service advisors, deliver a single-source logistics solutions across the UK and internationally, supporting projects in more than 120 countries across five continents, offering rapid delivery and tailored supply strategies.
With global electricity demand predicted to more than double by 2050, Thorne and Derrick International are strengthening and extending their world class supply chain to support grid-scale projects to drive our sustainable energy future towards net zero through renewable energy, digitalisation and decarbonisation of industry.
