Vessels, rigs and offshore installations rely on complex pipework systems that cannot easily be drained down at sea or in operation. Bishop Pipe Freezing pioneered the world’s first offshore pipe freezing application in 1977 and continues to provide pipe freezing and related services for marine and offshore environments where shutdown is impractical and downtime is costly.
Valve replacement on live seawater, cooling and fuel systems
Emergency repairs without draining critical pipework at sea
Hot tapping for new connections without taking systems offline
Planned maintenance fitted around tight operational windows
Line stopping for isolation during modifications and upgrades
Pipe freezing requires no system drainage, no refill and no re-commissioning. Work can be completed in hours rather than days, allowing repairs and modifications to be carried out without taking vessels or installations out of service. With decades of offshore experience, Bishop understands the demands of working safely in marine settings.
Pipe freezing is often the only viable approach when shutdown is not an option.
