Engineers at Texan firm NOV are developing a pigging machine that can be permanently installed on the sea bed. The Subsea Automatic Pig Launcher (ROV), can be operated remotely, has an internal cassette capable of holding up to 10 pigs, while a SAPL-operated ball valve barrier enables deployment with no disruption to production. NOV is building a prototype off the west coast of Norway, and expects tests to be completed during Q1 2018. It is also examining an all-electric version of the ROV.
