Halfwave said it has has been awarded two new in-line inspection (ILI) contracts by Woodside in Australia. The awards have been made as part of a Master Services Agreement (MSA).
Woodside is an early adopter of Halfwave’s ultra-wideband acoustic resonance technology (ART) inspection technique. Acoustic signals transmit readily through gas, so there is no need for a liquid coupling medium, and they penetrate internal coatings and surface deposits, such as wax within the pipe, far more effectively than traditional inspection methods.
The signal transmitters and receivers can stand off several inches from the pipe wall making ART pipeline pigs capable of negotiating pipelines with constrictions and internal diameter changes which would impede other ILI pigs.
Halfwave says the ART Scan is suited for the inspection of gas and liquid pipelines and is a non-contact, low friction, lightweight technology and only the polyurethane is in contact with the pipe wall.
The two new ILI operations are planned to be carried out in 2019 on the 20” x 54km Pluto Flowline and the 40” x 134km 1TL Trunkline.
Since Halfwave’s initiation in 2013, Woodside have been a strong supporter ART technology and have been active in qualifying and developing this next generation of ILI technology.
