General – CO2 Transport and Storage
Allseas’ Oceanic kicked off offshore works for the Porthos project (Port of Rotterdam CO2 Transport and Storage) with a special unexploded ordnance survey along the 20-kilometer pipeline route.
The ‘bomb hunt’ is one of several important pre-lay activities required before the Lorelay can install the 16-inch pipeline. Fortunately, the hi-tech imaging and sonar spread – capable of visualising objects up to 4 metres below the seabed – detected no explosives!
Allseas is the main offshore contractor for Porthos. The work includes installation, burial and commissioning of the pipeline connecting the future compressor station, located at the Maasvlakte, with the P18-A platform offshore.
The offshore pipeline is provided with a plastic insulation coating to retain the heat in the pipe and a concrete weight coating for stability on the seabed.
The Lorelay will commence pipelay late April with a pull-in to the compressor station, before setting off in the direction of the P18-A platform.
