Smart Subsea Solutions provided client representation on board the DSV Seven Falcon which was utilised to dewater, de-gas and mothball Ninian North fuel gas riser pipework ahead of Ninian North decommissioning. In addition two flexible sections, including one flexible pipe and one flexible riser were successfully installed increasing the service life of the fuel gas system between Ninian South and Ninian Central Platforms. Due to the complex nature of the project it was of paramount importance to continually interface with the Dive Contractor on board the DSV and the three platforms to ensure topsides readiness ahead of each procedure.
