Gravitek personnel have experience on many petrochemical sites, namely Engen, Sapref, Caltex, Zenex and Petronas Malaysia. This involved Ultrasonic Thickness Gauging (PCMS - Plant Corrosion Management Systems), Radiographic and Visual Inspection on various pieces of equipment and piping systems.
PCMS involves identifying TML points on piping systems using API guidelines, carrying out visual inspections to establish extent of external corrosion or CUI (Corrosion Under Insulation) and using UT and radiography to establish wall thickness and internal conditions of piping and welds. Monitoring on a regular basis is also carried out with the objective of putting together work lists for up and coming shutdowns.
Gravitek personnel worked on the Caltex Cape Town refinery in 2000 shutdown, where Dean was a team leader, overseeing and coordinating all rope access maintenance and inspection work during this shutdown. Gravitek supplied personnel for all (work at height) inspection and maintenance works in the 2007 shutdown at Chevron (SA) Refinery in Cape Town, South Africa.
