IMCA publishes information note on NDE testing of gas cylinders

The International Marine Contractors Association (IMCA) has published an information note on non-destructive evaluation (NDE) testing of gas cylinders. Advancements in NDE testing techniques for gas cylinders have been the subject of extensive discussion by members of the IMCA Diving Division Safety, Medical, Technical & Training Committee (SMTT). A dedicated workgroup of industry experts was established to take the issue forward and to develop an update of detail sheet 9.1 of IMCA D 018 – Code of practice on the initial and periodic examination, testing and certification of diving plant and equipment.

IMCA publishes world-wide diving personnel statistics

Figures published by the International Marine Contractors Association (IMCA) reveal that globally there was a reduction in offshore diving work in 2010, compared with 2009, possibly due to the economic environment. A peak of close to 3,500 diving personnel was employed offshore world-wide by 43 IMCA members (i.e. those who responded to the call for data). This compares with a peak of 4000 from 35 reporting companies last year so the reduction does not stem from fewer reports received. They also show that air diving operations exceeded saturation diving by approximately 50%, with a trend reversal in IMCA’s Europe &
