Incoming projects are analyzed by skilled engineers in the design office. Detailed general arrangement drawings and spool drawings are generated through the use of Auto-CAD before the workflow is planned into the workshops.
Once spools are completed, all weld details are logged by our welding engineers with a percentage selected for x-ray to ensure integrity. All major projects are subject to full weld mapping, a copy of which is provided to the client upon completion, giving total assurance of finished quality.

a) Surface preparation
All cleaned surface shall be inspected visually for surface cleanness and anchor profile. The steel surface shall be clean, dry and free from dirt, scale, oil, oxide, rust and other contaminations. The inspector shall compare the surface with the degree of cleanliness specified in the painting scheme, based related standard.
All surfaces not meeting the degree of surface preparation specified shall be rejected and re-cleaned at Contractor’s expense.
Inspection shall be done within four hours after surface preparation.
b) Visual inspection
Upon completion of coating application, all coated surface shall be given a final inspection for coating visible defects: sagging, swelling, wrinkling, cracking, blistering, catering, impregnation with abrasive and/or foreign matter, peeling off, oxidation and/or corrosion, inclusion of hairs and pores. The coating shall be free of all foreign matter, blisters, runs, skips and other irregularities.
c) Inspection of adhesion
The purchaser shall require adhesion Pull - Off test. The absolute minimum value of the test results is 5MPa.
d) Inspection of dry film thickness
For paint film thickness there shall be taken 5 measurements per m2, the average thickness shall not be lower than the specified DFT for each layer. No individual measurements shall be below -20% of the specified DFT, and the maximum shall not exceed 2 times the specified DFT or the requirements in the Coating System Data Sheet (CSDS) from Coating manufacturer.
e) Inspection record
A complete record should be made for all the inspection operations, which including inspected parts and locations, inspected apparatus used, inspection time and the inspector, the problem found.
