Eliminating risk using COLD WORK offshore repair

SPS Technology and our Network Partners deliver the world’s leading structural composite COLD WORK solution for offshore asset repair and new build. Using our proprietary material, SPS, we provide a permanent, class-approved, cost-effective in-situ solution for repair and strengthening across the offshore industry. Using a combination of surveying and offshore fabrication, SPS COLD WORK eliminates shutdown periods and keeps assets in production and personnel safe. 

SPS can be delivered as a hot work or COLD WORK solution to reinstate, strengthen, upgrade and provide superior protection on various offshore assets including FPSOs, FSOs, drilling rigs, semi-submersibles, fixed leg platforms, jack-ups, and OSVs. Suitable for working in ATEX environments, SPS Cold Work Solutions have been successfully delivered since 2003 on the FPSO INDEPENDENCE

SPS saves time and money:

  • requiring up to 90% less labour and 56% less steel than conventional techniques;
  • being up to 11x less expensive and 3x faster than steel crop and renewal; 
  • eliminating the need for dive boats and underwater cofferdams; 
  • allowing work in adjacent areas to continue in parallel;
  • helping shorten project schedules as the structure remains intact;
  • reusing the existing corroded plating as one-half of the composite; 
  • ensuring enhanced fatigue resistance and extended service life.

We meet international standards

SPS is approved by all major Classification societies including, but not limited to, ABS, Lloyd’s Register, DNV and Bureau Veritas. Guidelines and/or Rules have been published by the majority of International Association of Classification Societies (IACS) Members for SPS uses in asset construction and repair.

As a guideline to shipowners, ship managers, shipyards or surveyors, our Surveyor’s Pack is available for download. The Surveyor’s Pack showcases how SPS Technology’s technical expertise can guide your team in meeting the requirements of any type of offshore project: new build, maintenance or repair.


Ultimately the integrity of the assets and the safety of the crew and environment — coupled with the lifespan of the asset — are the primary concerns of any asset owner/operator. SPS was designed specifically for the Maritime & Offshore industry. This steel-elastomer-steel thermoset structural composite panel is a permanent structural repair and upgrade for any type of offshore asset, as well as offering advanced solutions to fire, chemical and threat protection.
