TDW Offshore Pipeline Flood Prevention Services 

 
The TDW Offshore SmartPlug® technology can be used for flood prevention to prevent pipelines or risers from flooding when they are laid or installed.

PIPELAY
The TDW Offshore SmartLayTM system is designed to increase safety in situations where the lay vessel may no longer be in control of the pipe, or in the event of a wet buckle. The SmartLay system is intended to protect the seabed portion of a pipeline under construction from accidental flooding, it can be configured to also protect the riser portion. Prevention of pipeline flooding enables quick recovery from a buckled pipe situation.

The SmartLay system is based on the SmartPlug pipeline isolation system, both are fully DnV certified. SmartLay activation is primarily automatic, onboard pressure, tension and water mist sensors trigger the system in just seconds. Standard SmartPlug communications are also fitted, thus enabling tetherless through-wall remote controlled setting and unsetting. TDW Offshore has tools available in every pipeline size from 10" to 42".

RISER HANDLING
Setting a SmartPlug system at the end of a dry pipeline before laying it down on the sea floor saves days of using a pipelay vessel. It also allows dry tie-ins, using less expensive vessels to pick up the pipeline from the sea floor at a later date.

Using a SmartPlug system during the handover of the pipeline from the lay vessel to the platform prevents flooding, should a wet buckle occur. The SmartPlug tool can also be used for flood prevention during lay down, lifting, or while placing the riser in the porch.
