Substantial Savings Achieved in Floating Pipeline
In July 2016, Sereant contacted MIPC bvba looking for a solution for their floating pipelines which required to be refurbished.
The full project had to be completed within a 15 day shutdown period. In some localised areas the pipeline showed severe pitting which would have to be repaired. Grit blasting was also not permissible and coating application had to take place in high humidity.
The only solution available in the market which could meet Sereant’s strict deadline would be to utilise a unique combination of water jetting and a solvent-free, wet & rust tolerant coating solution.
The pipeline was prepared by water jetting to WJ-2 standard. One primer coat of solvent-free, wet & rust tolerant epoxy Epo-chem™ RS 500P was then applied. This was followed by one topcoat of solvent-free, wet tolerant epoxy Epo-chem™ RA 500M.
The client received substantial time and cost savings by utilising this unique solution as the project was completed 4 days earlier than initially anticipated; which was helped by the short drying time of the Chemco coatings and their ability to ‘continue to cure’ underwater.
The following benefits were achieved by both the client and contractors who undertook the project:
- Solvent-free coating system
- No grit blasting
- No humidity or dew point restrictions
- No re-coating limitations
- Additional painting works could be executed
- Quick back-in-service time (project completed 4 days earlier than expected)
