Our Special Contract Service team was in Stockholm at the end of April 2005 to flow stop a 24” low pressure gas main in the very heart of the city, outside the government buildings. 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...

Specifically, the company was commissioned to design a method of safely removing one metre lengths of ducting without contaminated particles becoming airborne, to carry out on-site trials and subsequently supply application equipment and sealants which Sellafield operatives would be trained to use. The method devised by Steve Vick involved using the company’s patented FOAMBAG™ technique,...

A Special Contracts Team from Steve Vick International recently carried out a flow stopping project for Manx Gas on two 22” gas mains in Douglas, Isle of Man. Located on South Quay, close to a gas holder, the 200 metre sections of two-way fed main were being abandoned so that governors could be installed in order to connect into a medium pressure system. Two x two-way flow stop operations,...

Procord, the company which manages the land and buildings at Winfrith Power Station, needed to safely seal off two 180mm (6”) underground pipes. These pipes connect pits that are, respectively, 43 metres and 28 metres apart. As the pipes run under a concrete road that would have been costly to dig up and reinstate, Procord decided against removing the pipes, preferring instead to completely...

Live Gas Mains Insertion is a routine operation for Wales & West Utilities. In this project, they used Steve Vick International’s newly improved 125 pneumatic pushing machine with a 5” ram. The operation involved inserting 125mm PE into a 6” main in Wells, Somerset. WWU said that they found the pushing machine as powerful as a hydraulic machine and pushed the 94 metres of pipe in...

The project involved filling a sump and 3-4 metres of redundant 4” clay pipe that contained residual contamination from historic operations. Following several visits to the site and specific workshop trials – and based on previous experience of similar jobs for UKAEA – Steve Vick International successfully completed the sealing off operation using the Foam Bag™ system, in half a...

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...

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...
