Media Release: Denholm MacNamee poised to strengthen Norwegian and North Sea presence


A LEADING provider of innovative asset cleaning and decontamination solutions has announced that it is poised to further enhance its North Sea operations thanks to a significant new agreement.

In 2011, Inverurie-based Denholm MacNamee became the approved, exclusive UK license holder for ZymeFlow® Decon Technology.

The license includes a suite of chemistries and patented applications known worldwide for the decontamination of refinery and petrochemical process units in 8-12 hours.

The system has successfully been used onshore in refineries and petrochemical plants for decades, in addition to Denholm MacNamee taking it offshore.

Such has been the success of the venture that the company has now been able to extend its remit to cover the whole of the North Sea, including offshore Norway.

The move has been brought about thanks to excellent results achieved using this cost-effective, small footprint, and quick entry method which has been positively deployed in large offshore projects for several major operators in the UK North Sea.

The additional geography opened up by the new agreement will enable Denholm MacNamee to take United Laboratories International’s (ULI) ZymeFlow® Decon Technology to a wider audience, and work in synergy with other products and services in the Denholm MacNamee portfolio.

In a single process, ZymeFlow® Decon Technology treats the vessel contents whilst eliminating pyrophoric iron sulphide (FeS) and hydrogen sulphide (H₂S) and liberating LEL and benzene to enable fast and safe vessel entry.

Solids in the vessel are de-oiled and conditioned for ease of removal and disposal.

The dynamic chemistry utilised is also non-toxic, non-hazardous, biodegradable, near neutral pH and compatible with all metallurgies and process equipment – a very attractive option especially for markets with strict environmental regulations such as the North Sea.

Denholm MacNamee managing director, Brian Ritchie, said: “There is no doubt that, with costs under scrutiny in these challenging times, methods such as this unrivalled system offer attractive faster, safer, and more efficient solutions and there is clearly a strong appetite for solutions such as ZymeFlow® Decon Technology.

“We look forward to building on the significant successes already recorded in the UK North Sea to extend our reach as well as using project completions and knowledge gained as a springboard to capitalise on future opportunities in the region as a whole.”

Tom McQueary, president of ZymeFlow® Decon, said: “The success that Denholm MacNamee continues to have in offshore vessel decontamination is very exciting for the whole organisation.

“The combination of such an ideal product for this market and the offshore experience Denholm MacNamee brings to the table has brought significant benefits for both organisations. We look forward to building on that relationship as we enhance our presence in this key marketplace.”

Denholm MacNamee is a leading one-stop provider of asset cleaning and decontamination solutions to the oil and gas, petrochemical, power generation and utilities industries and works closely with customers to provide bespoke, uncompromising solutions which give the option to combine services whilst considering key issues such as cost and schedule delivery.

The company uses state-of-the-art equipment backed by experienced, professional technicians to deliver solutions which are always tailored to the requirements of each client to ensure a bespoke service.

Denholm MacNamee is exhibiting at ONS 2016 in Stavanger from August 29th until September 1st.

The company will be welcoming visitors to stand 5310 in hall 5.
