Inspection of Ballast Tank Plates and Welds Using SIMS Sonomatic were engaged to work on a Spar platform in the Gulf of Mexico to inspect the bottom of the ballast tank. Read on to learn more.
INSPECTION AND INTEGRITY ASSESSMENT ON UNPIGGABLE DRY GAS PIPELINE SUBSEA A client operated a number of subsea pipelines in dry gas service. These lines were not designed for in-line inspection but had been in service for some time and a validation of their condition was necessary. The inspection to validate condition was, therefore, to be performed using externally applied tools.
ADDED VALUE FROM REPEAT INSPECTIONS Every year Sonomatic not only carries out numerous repeat inspections for their clients globally, but also, by the means of specialist statistical analysis, helps to determine the fitness of an installation, essential to planning its future maintenance.
NII PLANNING IMPROVES SHUTDOWN EFFICIENCY Sonomatic were approached by a client to perform Non-Intrusive Inspection (NII) planning on 53 vessels, as NII offers the potential to remove vessels from shutdowns and inspection may be completed whilst online. This can reduce shutdown times and increase production revenue.
CORROSION MAPPING ON CAISSONS TO DETECT AND QUANTIFY WALL THINNING Sonomatic were approached in order to provide an automated solution for the inspection of caissons. This was to prevent any potential health, safety and environmental consequences that can arise by using divers.
