TSG/Pipe Repair with SPS is a permanent class-approved pipework repair solution used where structural integrity, containment, or protection against corrosion is needed. This in service, no hot works bolted design is a cost effective alternative to pipework replacement.
SPS (R) is a structural composite where two metal plates are bonded to an elastomer core, has been providing innovative, permanent, class approved repair solutions to the Marine and Offshore industries for 20 years.
TSG/Pipe Repair with SPS has been developed and verified by DNV GL. Working with DNV GL, TSG/Pipe Repair with SPS has been approved under the Technology Qualification process. The product has been developed using a top down approach that assesses an assembly to gain an understanding of the complete system and the compositional sub-systems.
TSG/Pipe Repair with SPS has been developed within TSG Marine’s Quality Management System and in line with our accreditation to the ISO9001 standard.
TSG/Pipe Repair with SPS is impervious to most product medias and environments. The original pipework can completely corrode/erode, leaving the elastomer as the corrosion and thermal barrier to the outer clam shells. Redundancy has been built into this repair solution. The outer clam is designed to contain the full system pressure of the original pipework without the elastomer core being injected.
TSG/Pipe Repair with SPS has been designed to factor in the continued deterioration of the original pipework. In situations where the internal metal loss continues additional TSG/Pipe Repair with SPS sections can be bolted to the first repair. This subsequent repair can again be carried out with the pipework in service.

Pipework generally has a good safety record due to good design, materials and operational practices. However, like any engineering structures, pipes do fail. The most common cause of damage and failure is external interference (mechanical damage) and corrosion. A pipe will invariably develop defects during its lifetime and will require a “fitness-for-purpose” assessment to determine whether or not to undertake repairs. Replacing damaged pipework can be viewed as the ideal repair solution, particularly when the pipework is classed as safety critical. However, replacement may not be practical and/or cost effective and therefore viable repair methods are required.
An outer fabricated steel shell consisting of two clam shells encapsulates the damaged area of pipework. Inside radial seals are fitted at each end of the clam shells and longitudinal seals are fitted to the longitudinal flanges. The clam shells are then bolted together and the elastomer injected to bond the clam shells and pipework together. This creates a permanent structural SPS repair. This SPS elastomer core becomes a permanent protective lining, creating a bond with the original pipework.
