MMC Diving Services feel very privileged to have been appointed as the Diving contractor to undertake the welding of 996 galvanic anodes, with 458 dives undertaken and 49,000 minutes spent underwater welding, MMC Divers completed these works within 10 months, on time and in budget.

Following our previous works on the QEC jetty in 2016 and 2017 for HMS Queen Elizabeth aircraft carrier, this project was of a similar nature and was part of the upgrades to improve both Victory and Sheer jetty so that both 65,000 tonne leviathans can be in port simultaneously.

Our onsite superintendent was responsible for supervising the entire operation and ensuring the work undertaken by MMC was carried out to the required specification while also being responsible for the recording and logging of all site works, site specific dynamic RAMS as well as coordinating all activities undertaken by our teams, from rope access, cable pulling, barge movements, vessel operations and all associated lifting operations. Our MMC teams were made up of cross trained surface supplied divers, City & Guilds Confined Space High Risk & Rescue, IRATA rope access engineers, Forklift and telly handler operators and Commercially endorsed vessel operators.

Routine audits were undertaken internally and externally to ensure that the high standards were maintained throughout the works, Emergency preparedness drills are a big part of our daily activities and safety culture, these were all logged and recorded.
