About

Our History

Originally, Prior Diesel Limited was established in 1980 as an extension to George Prior Engineering in Great Yarmouth who carried out repair work on vessels operating in the North Sea. During the 1980s and 1990s many offshore support vessels owned by Tidewater Marine whose HQ is in the U.S.A. were powered by Detroit Diesel 2 stroke engines. Prior Diesel carried out numerous engine overhauls and repairs during this period and from this was awarded a Detroit Diesel dealership to help support the growing business from this product.

The growth of the company continued and in 1991 Prior Diesel moved to a new purpose built industrial unit to meet the high demand of our specialist services with many other leading engine manufacturers wanting to have Prior Diesel as their extended arm for supporting their products in the market place. Today we are a supplier for Baldwin Filters, Cummins, Detroit Diesel, Deutz, Finnings CAT, Fleetguard, FPT, Lister Petter, Perkins, Scania, Separ Filter, Sullair and Volvo Penta.

With all these prestigious engine manufacturers falling under the Prior Diesel banner the Parts Department thrived and alongside the engine repairs built a strong relationship with UK and overseas clients in many sectors of industry supplying spares to all corners of the globe.

Prior Diesel’s wealth of knowledge and experience gained through servicing major clients in the North Sea for many years has led to the expansion of our offshore support department. The Prior Diesel name is very well known in the offshore industry for offering a fast response and reliable service that can be relied on to keep downtime to a minimum to maximise production. Providing labour only to completely refurbishing equipment or supplying new replacement products Prior Diesel has the solution to meet the customer demands.

Prior Diesel became part of the Suretank Group – in turn owed by HitecVision – in January 2015 – a world-leading manufacturer of engineered Cargo Carrying Units (CCUs) and tanks for the offshore oil and gas industry.

HitecVision is Norway’s largest private equity investor, headquartered in Stavanger.  The company invests in the offshore energy sector, making significant growth investments in natural gas and oil producers as well as energy infrastructure and renewables.

In February 2020, Prior Diesel became part of the newly-formed Moreld group of companies under HitecVision’s portfolio – a group of 20 worldwide companies representing 3,600 employees.

In our 40th year and to align ourselves with the direction of growth of energy supply, we became Prior Power Solutions.

With the Paris Agreement committing to combat climate change and to accelerate and intensify the actions and investments needed for a sustainable low carbon future, whilst oil and gas markets will continue, there is increased investment and development with sustainable markets such as renewable energy.

Prior Power Solutions will continue to support customers with diesel products, but more importantly we are:

  • Developing an electrically driven range for all the diesel-driven well service equipment we manufacture and designing new, innovative products.
  • Investing in our staff and training as technology advances. With our association with all the leading engine manufacturers we are in a great place to do this.
  • Widening our capabilities and knowledge with hybrid systems, hydrogen power and all new emerging clean power products through R&D and partnerships with academia and industry leaders.
  • Our team is our strength and as a credible British manufacturer with 40 years industry-specific experience our ambition is to secure our position as a leading global player in the field of sustainable power solutions.

Our headquarters in Great Yarmouth cover 2,800 sqm and consists of the original building plus two additional purpose-built manufacturing units and testing facilities.
