Project Reports

Guernsey Gas has carried out the first live insertion of a gas main on the island for two decades. The project involved renewing 126 metre of cast iron main in Le Pollet in the centre of St. Peter-Port. A technician from Steve Vick International Ltd, the company which supplies equipment for the technique, was on site to offer help and advice. Only one excavation was required for the insertion,...

Steve Vick International Ltd was recently retained to carry out works at Chapelcross for the nuclear decommissioning company Magnox North. The works required Steve Vick International engineers to seal off a number of redundant manholes – 43 in total – each containing between two to six inlet and outlet pipes of varying sizes from 20mm to 12”. The deepest manhole was 1.5 metres and the...

The 6” low pressure main in the High Street of Paulton, near Bristol, was being replaced with a new PE pipe but one section needed to be kept live as it was feeding three homes. The National Grid Transco team used a FOAMBAG™ kit to flow stop the section to be abandoned before cutting out and tying the new PE to the live section. One-way traffic was maintained in the narrow, busy street....

Steve Vick International has been working with Corus Process Engineering (CPE) to provide sealing solutions for redundant sludge and effluent lines at Sellafield. The latest project is to eliminate any potential fault scenarios on the plant and reduce operator dose uptake during implementation by avoiding the need to drain the effluent tank pipes of radioactive sludge before the sealing...

A two kilometre section of the main, which was cast iron at one end and steel at the other, was to be abandoned. The team installed two double-skin FOAMBAGS™ at each end of the section. Once the expanding foam was cured, the main was vented and then purged using Steve Vick International’s new Mini Purge Ejector. It took just 45 minutes to purge the gas from the abandoned main. The team then...

This medium pressure gas main had previously been blanked off but the valve, acting as an end cap, was leaking. The customer, Manx Gas, decided that using the FOAMBAG™ technique to seal off the pipe was a costeffective alternative to conventional flow stopping methods. The project was carried out by our Special Contract Service team.

A leaking drain which was causing waste water to enter the basement pool complex of a luxury Kensington town house was successfully sealed off by Dyno-Rod using the DRAINBLOCK BAG™ technique developed by Steve Vick International. Dyno-Rod franchisee, Candid Services Ltd of Staines, Middlesex, were called in when the home owners found water on the floor around their underground swimming pool....

Bristol City Centre has recently undergone a major water mains replacement project in the heart of the city centre directly outside of the busy Bristol Hippodrome. The old 7”cast iron water main had been laid over 90 years ago. During the past 10 years the water main had experienced pipe bursting issues on 6 occasions and therefore was made part of Bristol Water’s 2009 replacement...
