Achillies Registration

Feb 2014. DTEC are now qualified onto the Achilles Joint Qualification System. A complete audit of the DTEC Occupational Health and Safety system to ensure compliance with NORSOK standard S-006 was a complete success. External auditors were from Statoil.

ECITB approval

Over the past twelve months DTEC have worked closely with the ECITB to develop a new ECITB accreditation for Confined Space Entry. DTEC are now an approved supplier of the ECITB Confined Space Entry accreditation and in February 2014 delivered their first course witnessed and audited by the ECITB.

DTEC open CoaST Academy

March 2013. DTEC have completed the phase one build of their Competency and Safety Training  Academy (CoaST Academy). The Academy boasts one of the most advanced Confined Space training facilities in the country. The unit has over 30 metres of different diameter enclosed pipe runs coupled by three multi level chambers and height access points. This, coupled with a mock refinery column makes training at the facility not only comprehensive but also, an interesting and enjoyable experience. The Academy will ultimately sell training courses to external bodies but in the first instance, is being used to train both DTEC and Engenda Group workers.

DTEC move to new 12,000 sq ft office and warehouse complex

September 2012. DTEC are proud to announce that the company has moved to a new premises at the Hixon Airfield Industrial Estate at Hixon in Staffordshire. The move will facilitate DTEC with much needed additional office space to house new incoming operational personnel and will enable ambitious plans for the construction of a new confined space and height training facility. Managing Director, Steve Colclough, quotes “We had outgrown the old premises some time ago and the group owners, Engenda, were keen to have us relocated to something more modern and in fitting with our growth plans. In the coming months we will be building a new training facility to compliment our Column Rescue company and to enable us to provide personnel training for companies across the Engenda Group”.

DTEC join Engenda Group

February 2011. DTEC have become part of the Engenda Group. Managing Director Steve Colclough is delighted that DTEC have struck a deal with Runcorn based Engenda whose other group companies offer complimentary capabilities to those of DTEC. The move will enable DTEC to proceed with its ambitious expansion plans with the benefit of stable financial backing and a broader service offering. DTEC will continue to operate from its Staffordshire based headquarters. For more information on Engenda follow the Engenda web link under our links tab.

2010 Vclad Weld overlay update

The Vclad® Weld Overlay business line has enjoyed a successful 2010. We have executed a number of highly engineered contracts to a variety of corrosion and erosion related repairs. We also launched our Emergency Response Service (ERS), this service is designed to provide plant operators with an assurance plan that will enable the early and effective repair of corrosion damage that had not been previously identified and planned for in the TAR event.  The service was efficiently demonstrated during a Q2 turnaround at a major UK refinery….

DTEC were contracted to make a repair to the inside of a 72” Vacuum tower transfer line which was suffering from internal corrosion and erosion to the extrados of a number of bends. We developed a bespoke automation setup to provide a multi layer weld overlay using a high nickel filler material. As part of the contract we also included for our Emergency Response Service (ERS).  The service provides automation equipment, power sources, tooling and consumables to be mobilized to site prior to the start date all at pre-turnaround agreed rates. This service ensured that we were able to react to emerging workscope as and when the vessels were opened for inspection…….

 Early during this turnaround the client found severe corrosion to the lower segment of a drum on the Alkylation unit. We were able to immediately start preparation, by working with a heat treatment provider to bake out the vessel in readiness to make this repair, which consisted of applying a 5mm Thk carbon steel weld overlay build up. During this time we had a further requirement for our ERS on the Vacuum tower, this tower required repairs numerous elevations:  we provided shell wall weld overlay to extend below an existing band, provided localized repairs to internal equipment and made full circumferential seam repairs to a shell strake transition joint which was suffering from severe in-weld corrosion.

During this ERS contract we were able to mobilize and de-mobilize as the workscope increased/decreased whilst all the time maintaining the level of equipment and consumables required to react to the demands of the turnaround.

Following this contract we executed another interesting repair at a refinery in Belgium. The process vessel was suffering from Corrosion Under Insulation (CUI). This repair comes with its own challenges, as this is an external repair to the vessel there are commonly access  restrictions and weather elements to consider.  This repair required a multilayer build up with a carbon steel consumable. We fully automated these repairs to numerous locations/elevations. One particular repair area required up to 4 layers to achieve thickness criteria.

Our final project highlight of the year was the execution of approximately 55m2 of weld overlay to a process vessel at a UK chemical plant. The consumable was a nickel based alloy. This repair required the use of multiple systems and also included the lower dished end – which was also welded using automated equipment. During this turnaround we also executed a number of emergent repairs to circumferential and vertical vessel seams, again these were repaired using Vcald® automated welding technology. 

So, overall a successful year that demonstrated the benefits to our customers that DTEC provides a full turnkey service, from isolation, inspections, equipment removal/reinstatement, corrosion repair, weld overlay and de-isolations. Please feel free to contact us to discuss any of the above repair scenarios as well as our ERS emergency service.

2010 Turnarounds.

DTEC have enjoyed a busy first two quarters in 2010 completing major turnaround works at Murco, Sabic, DOW Chemicals, Conoco Phillips and Chevron. The Murco TA came in at just under 20,000 accident free manhours and included a re-vamp of the upper VAC Tower along with multiple column inspections and repairs. Work peaked on Murco and Sabic with over 100 contract personnel in the field. Efforts to expand DTEC’s overseas activities have also been successful with first contracts being completed in China, Algeria and Saudi Arabia.

Petroplus Coryton TA

22nd Novemver 2009. DTEC completed one of its largest Turnaround Events to date for Petroplus Refining at Coryton Refinery. This was a multi column workscope across several units including the Alkylation plant. Initial work was to open columns for inspections and perform scoped work including a partial revamp of the Acid Settler. Inspections determined a wide variety of emergent work for which DTEC provided emergency supply of tower attachments, trays and hardware. Additional resources were provided to perform the additional work which  included tray ring removals and installations, fully welded tray installations and bolted internals changeouts. The work was completed in 19,400 accident free hours with peak manning of 48 men.
