Clock Spring Composites

Composite Restores Riser Integrity Offshore

When a corroded riser was found on an oil platform offshore Africa, the owner needed a solution that would minimize production loss. But this was a challenging repair. The damaged riser included a section of pipe that had been welded, creating an uneven surface; so in addition to addressing corrosion, the repair would have to contend with alignment and weld bridges.

Clock Spring had the answer – the Clock Spring composite repair sleeve and reinforcement system.

Clock Spring-trained and certified technicians prepped the line and filled in the corroded areas, then applied Clock Spring repair sleeves to the riser, restoring the line to safety without requiring production to be shut in.

Composites Restore Pipeline Integrity in Gujarat

When unauthorized surface excavation damaged a buried gas line in Gujarat State, India, the line operator, GSPL, called in Clock Spring to help find a solution. Working through Allied Engineers, an authorized local distributor, Clock Spring resolved the damage and restored the line to safe operations.

In all, the team repaired 22 m (72 ft) of the pipeline, with an average daily repair length of 2.5 m (8 ft). Using Clock Spring sleeves allowed the BAKPL line to be returned to full operational integrity.

Creative Solutions Improve Worker Safety

   |   By  |  0 Comments

The oil and gas industry today is safer than it has been at any other time in history, but US statistics indicate workers in upstream oil and gas operations have one of the highest accident rates across industries. A huge amount of legislation and a long list of regulations have been put in place to address the dangers inherent to upstream oil and gas operations, so why is the number of lost time incidents, injuries and fatalities still high?

Clock Spring President and CEO Matt Boucher looks for answers.

IndustryVoice: Composites Repair In-Service Topside Piping System

   |   By  |  0 Comments

Maintaining asset integrity on offshore structures is a priority, which is why owners invest in developing regular maintenance programs to identify irregularities as soon as possible. During a scheduled inspection on an offshore production unit working offshore Africa, workers discovered corrosion on a 26-in. (660-mm) topside production piping system. The pipe needed immediate attention, but the owners did not want to shut in production while the repair was being made. They contracted Clock Spring Company Inc. to provide an engineered composite repair solution to be carried out with the critical production line in service.

The complete pipework had suffered severe external corrosion that affected straight pipe lengths, girth welds, pipe support, T’s, tight radius bends and offtakes. Clock Spring engineers determined the extent of the corrosion and performed a complete in-house engineering analysis to develop a bespoke repair solution that was manufactured in the company’s design facility in Houston.

Because of the range of areas affected, the solution included Clock Spring fully cured laminate as well as Clock Spring Contour wet layup repair, which would be used for the complex geometry configurations. Clock Spring engineers presented the client with a detailed design report outlining the complete repair in accordance with both ASME PCC-2 and ISO TS24817 guidelines.

A team of Clock Spring-trained and certified technicians installed standard Clock Spring 8-layer pre-cured coil sleeves to the straight piping sections, pipe supports, girth welds and 12-inch (305-mm) offtake systems. Because of the extent of the corrosion, installers applied high-compressive-strength filler by hand, molding it in place before installing the Clock Spring coils. The limited clearance between the pipework and deck grating required installers to use a spool feeder to place the repair sleeves.

With repairs made to the straight pipe runs, the team turned its attention to the complex geometry sections that interfaced with the reinforced sections. Clock Spring engineers designed the Contour system specifically for this repair, supplying materials to the work site in component form and mixing them by hand to form the composite repair around the structure on site.

With the repair complete, the topsides was restored to a safe condition for extended service. The Clock Spring design team not only provided safe, quickly executed and effective specialized repairs, but offered complete engineering support following installation.


  • 26-inch (660-mm) topside production piping system; and
  • Severe external corrosion .



  • Clock Spring and Contour repairs were carried out to restore extensively corroded 26-inch (660-mm) topside production piping system on an offshore asset;
  • The complete pipework was subject to severe external corrosion that affected straight pipe lengths, girth welds, pipe support, T’s, tight radius bends and offtakes;
  • Clock Spring engineers designed a specialized composite repair solution that addressed straight pipe as well as complex pipe geometries; and
  • Production continued while repairs were carried out.
