AONDE INSTALLATION GAS PIPELINE NORTH SEA

Subsea works by Aquatech Offshore

Project description

In 2022, Aquatech Offshore was engaged to carry out two distinct anode installation projects using the DSV RS Sentinel.
Our expertise in subsea operations ensured the successful completion of both tasks within a tight timeframe.

Specialized subsea services by Aquatech Offshore:

Anode Scope 1 
• Conducting ultra-shallow DP2 DSV operations with less than 6 msw under the vessel’s keel
• Welding of earth connection to the existing cathodic protection system
• Installation of a Bracelet Anode on a 36” gas pipeline

Anode Scope 2 
• Design, fabrication, and installation of four custom-made anodes
• Execution of complex diving tasks inside a subsea dome at 28 msw
• Use of Nitrox diving to enhance safety and operational efficiency

Aquatech Offshore played a vital role in the execution of both projects, delivering high-quality results within just 7 days. These operations demonstrated our ability to operate in ultra-shallow waters, perform precise subsea welding, and carry out complex intervention tasks under pressure.
