Lifetime Extension

OPS Solutions has performed structural composite repairs according to ISO 24817 on several installations on the Norwegian sector over the last 20 years.

Composite structural repairs according to ISO 24817 is a fast and flexible repair method for corroded or damaged steel pipes to maintain piping system integrity. The composite repair can be performed on hot operating systems reducing the operational down time to a minimum.

OPS Solutions treats each structural composite installation as a unique repair. OPS Solutions is not providing repair kits but is designing the structural repair system after thorough check of background information of each repair.  

The excellent communication between highly skilled installers and our composite repair designers provide the customer/system owner a unique and flexible repair system with a very fast response time.

DNV-GL has performed a successful evaluation of OPS repair system and installation methods.

OPS Solutions has an excellent project track record for ISO 24817 offshore structural repair and has performed over 500 successful offshore composite repair class 1, 2 and special items class 3, for major oil companies.

OPS Solutions is listed in Statoil TR3016 as approved supplier for composite repair.

What we deliver

Engineering and design
+

OPS Solutions builds on 25 years of experience of designing and manufacturing composite structures for tough conditions and demanding customers.

Competence is the backbone of the operations, from engineering and design to manufacturing and installation, with formal and relevant experience across all parts of the operation.

OPS Solutions provide composite material experts from design to installation.

Own R&D resources within composite materials ranging from MSc to PhD level and significant experience on design and Finite Element calculations of composite structures.

Capability to undertake various advanced structural finite element analyses (by means of Ansys and Inventor Pro) and design (by means of Inventor 3D and Auto Cad).

OPS engineering department can provide: 

  • Product development and feasibility studies
  • Prototype design and production
  • Structural analyses
  • Design and detailed engineering
  • Piping and stress analyses
  • Structural tests
  • Compliance check with codes and regulations, Norsok, PED, ATEX, ASME X, ISO 13121, DNV C501 etc.
Wrapping

OPS Solutions has installed advances structural repairs according to ISO24817 on several installations on the Norwegian Continental Shelf. In total over 700 successful repairs performed offshore for oil companies, including repairs in class 1, 2, and special repairs.

Composite structural repair, wrapping of pipes, tanks and other equipment can be used as both temporary and permanent repairs. This methods can be used when there is limited access to the pipes, it is prohibitively expensive to replace the pipe, or a full replacement is too time consuming.

We are using our own OPS Wrap where each installation of a repair is customized according to its individual requirements. This is made possible by the combination of highly skilled installers and our composite repair designers provide the customer/system owner a unique and flexible repair system with a very fast response time. OPS Solutions is not providing already prepared repair kits. 

  • All of the material properties used in ISO 24817 laminate calculations are tested and compared to Finite element calculations and laminate testing.
  • GRE material for wrapping repairs is tested by an external laboratory and the values are on ply level.
  • Every new combination of resins and substrates must be tested to obtain a comparable value of laminate/substrate surface strength.
  • We verify the all results by using Finite Element Analysis to recalculate values of laminate properties, peel strength, and shear strength based on test results.
  • The repairs are executed by qualified and experienced operators with both theoretical and practical training.
  • DNV GL has evaluated OPS wrap and OPS installation methods.
  • OPS is an approved supplier for composite repair according to Equinor technical requirement TR3016
