Offshore Oil & Gas Diving Services

Gage Roads Diving Pty Ltd offshore oil & gas diving services

In 2010, Franmarine Underwater Services’ Diving Safety Management System (DSMS) was approved by the National Offshore Petroleum and Safety Authority for operation in the hydrocarbon exploration and processing industry of Australia. To separate and manage our statutory obligations associated with administering our DSMS, Franmarine established a new offshore diving company, Gage Roads Diving Pty Ltd.

Gage Roads Diving Pty Ltd has been steadily acquiring the necessary equipment required and has recently finalised preparations for a full offshore diving system to be operational. The system features a new DNV-rated containerised decompression chamber, 5 x 180 metre umbilicals with underwater CCTV, KMB 37 diving hats and LARS.

Gage Roads Diving Pty Ltd officially opened its doors for business in 2011.
