Pipetech mobilised to clean and treat a gas import riser which could not be cleaned by conventional methods due to the line configuration and platform layout.
Using Aqua Milling®, the specialist nozzles and rotational hose negotiated 6 bends to 140mtr depth at 950Barg working pressure.
A Specialist Cleaning team working along with an Inspection provider successfully completed a capability demonstration for the client onshore in Bergen, Norway ahead of mobilising offshore. This proved Aqua Milling® ability to negotiate tight bend configuration.
