List of Services (by sector)

1. We provide all forms of conventional and advanced NDT services utilising Rope Access methods. This includes pipeline integrity inspections such as CUPS (Corrosion under Pipe Support) and CUI (Corrosion under insulation) as well as general visual inspection.

2. We provide general maintenance for oil tank storage fire protection system foam and water lines.

This makes the sprinkler system ineffective due to leakages and clogged nozzles.
