SPC’s seawater inlet/outlet facility.

Jotun Saudia Company has recently completed two major paint supply contracts for projects in Jubail, Saudi Arabia.

The projects, which were awarded this year, involve the provision of suitable paint systems for a cooling tower at Jubail United Petrochemical Company (JUPC) and a seawater inlet/outlet at Saudi Polyolefin Company (SPC).

Both these facilities are concrete structures and the paint system selected is required to provide a 10-year warranty, says Hans Berglund, sales manager (protective coatings and marine) of the Dammam-based paint manufacturer.

'Jotun was selected as the preferred supplier because of the proposed work procedure, the good references it has gained from its earlier projects and the technical service and support it provides during the progress of the work at site,' comments Berglund.
Given its wide experience in concrete protection, Jotun is well aware that the most important factor in ensuring excellent results is the pre-treatment of the surface.

'Blasting is a must to remove all laitance, contamination and to surface all blow holes and cracks as well as to create the required surface profile to ensure the best adhesion for the selected paint system,' he says.

'Projects such as these require the best teamwork between contractor and supplier,' he adds. 'The main contractor for SPC's seawater inlet/outlet project was Samsung and ABB, and the subcontractor was Nasser Al-Hajri, and this team has shown the best levels of performance while meeting the quality level set for the work.'
The main contractor for JUPC's cooling tower project was Fluor Daniel and the subcontractor for painting was Technical Contracting Corporation (TCC).

'This is the first cooling tower to be built in concrete in Saudi Arabia - with more being in the pipeline,' Berglund adds.
Both projects have been supervised by Jotun's technical service personnel who maintained a daily log of all the work that was carried out.

The project involved:

  • Blasting of the concrete;
  • Priming with Penguard clear sealer (diluted);
  • Filling of all blowholes and cracks with epoxy putty. Jotafloor solvent-free primer mixed with aggregates was applied twice with grinding undertaken between the coats;
  • Application of two coats of Marathon glassflake epoxy at a thickness of 400 microns per coat.

    All painted surfaces have been thoroughly checked with holiday detection equipment to spot any failure/pinholes, and the necessary touch-up has been done to meet the quality standards set for the project, Berglund says.

    'All parties involved, including the consultant's main contractors and clients, are more than satisfied with the quality of work and are confident of the long-term protection the systems will provide,' he concludes.
