Location: UK North Sea

Client challenge

A North Sea drilling contractor faced a challenge with rerouting a pipeline system for their drilling package on an offshore rig. They needed a solution that was not only safer but also more cost-effective and time-saving than traditional hot work methods.

What we did

To meet our client’s needs, we obtained approval for a 10” carbon steel 150# Quickflange™ connector, which was ideal for horizontal installation on the asset’s lower deck. Despite facing initial discrepancies with the wall thickness from the listed piping specifications, we included extra match boring equipment in the quotation along with installation tools, testing, and cutting equipment.

We used orbital cutting equipment to cut the pipe and manually prepared the installation area. Wall thickness checks revealed the need for match boring to align the pipe’s wall thickness schedule with the supplied Quickflange™ connector. After completing the match boring, the installation proceeded successfully, passing a hydrostatic leak test.

Results

Our solution resulted in highly positive outcomes for our client. The installation process was significantly faster compared to traditional hot work methods, and the Quickflange™ option provided a simpler, more straightforward installation which was also more cost effective, without the need for permits and habitats. Our technician, proficient in Quickflange™ installation, pipe cutting, and match boring, proved invaluable as only one technician was required, saving space on the client’s onboard asset. Overall, the successful project demonstrated the advantages of our approach in terms of efficiency, safety, and cost-effectiveness.

Client: Major North Sea operator

Location: Central North Sea

Scope

Quickflange™ technology was identified to repair a leaking 4” Sch80 carbon steel nozzle feeding from a diesel tank. Hot work was not an option due to both time constraints and the extreme space restrictions with the nozzle being located in a void which was too small for a welding habitat. 

Solution

ICR’s standard installation equipment was mobilised, which was able to contend with the tight clearance, limited rigging options and space restrictions – having only limited clearance to the nearest I-beam obstruction. The technician mobilised was ‘confined space entry’ trained in order to complete the install in a safe manner. All items were mobilised within 48hours, minimising the client’s downtime. The Quickflange™ joint was also tested post installation, to ensure the integrity of the connection and that it conformed to industry and client standard.

Results & Benefits
  • No hot work 
  • Extreme space restrictions were met with no issues, something no other competitor could match 
  • Equipment mobilised 48hours from initial request 
  • Reduced cost due to minimal downtime

Major North Sea OperatorUKCS
Scope

A major North Sea Operator was required to complete a dump cooler modification scope with a 10” Cunifer seawater line during a quick turnaround shutdown scope for a Floating Storage and Offloading vessel. Pipe removal and replacement with the use of 10” 5.5mm FF Cunifer flange connections was necessary for replacement of this cooling water repair scope. Quickflange™ was the preferred choice as a cold-work application. 

Solution

 A Quickflange™ solution was delivered which had undergone leak testing, mechanical testing and burst testing to meet the required criteria for DNV Type Approval Certification. Due to time criticality and personnel limitations on board, two multi-skilled ICR technicians were mobilised to complete this scope on back-to-back day and night shifts. The highly competent technicians held the following certification: Clamshell Cutting, Advanced Quickflange™ Installations, Flange Joint Testing and MJI10 Bolting & Torquing. The technicians completed: 

  • Prepping the pipe and performing two straight cuts with clamshell cutting equipment 
  • Installation of 2 x 10” 5.5mm CuNi 90/10 16/20 Quickflange™ Connectors 
  • Flange strength testing of both connections utilising flange joint testers and ancillaries 
  • Bolting and torqueing of spools to tie-in the new pipework 

During the first of the Quickflange™ installations, the pipe was found to be oval once the cut had been performed with the clamshell cutter. This scenario can occur where the pipe ‘springs’ once the cut has been made due to tension in the pipework. The technicians used tried and tested techniques to bring the pipe to within the required outer diameter tolerances allowing the Quickflange™ to be installed. The technicians also remained to assist the shutdown team with other modification work on the asset ensuring the full scope of work planned for the shutdown was completed on time and to the highest of standards. 

Results & Benefits
  • Work successfully completed over a 3-day period; technicians on 6 back-to-back shifts cut, installed and tested the Quickflanges™ 
  • Long-term safety of system improved by permanent repair 
  • Safety, time, production and cost savings compared to conventional welding
