Innovation<br />
Earlier this year we reported the<br />
creation of a new role within the<br />
business, that of Innovations<br />
Manager. The appointment was filled<br />
by Kevin Halpin.<br />
The appointment has brought a new<br />
dimension to the way in which we are<br />
capturing and driving innovation<br />
within the business.<br />
“We now have a much higher level of<br />
engagement with research and<br />
development within our supply chain,<br />
and are developing ideas and initiatives<br />
into viable proposals that potentially<br />
will offer value to the business.”<br />
To ensure that we are capitalising on<br />
innovation and best practice across<br />
all our contracts, and are therefore<br />
delivering best value to all our clients,<br />
we have formed a cross-company<br />
innovation forum. “The forum<br />
comprises of delegates from across<br />
the company sharing best practice<br />
through meetings, workshops and<br />
video conferencing.” stated Kevin.<br />

Electrofusion Clamp<br />
Detection<br />
The following innovations are currently<br />
being used on or trialled within our<br />
contracts:<br />
Electrofusion Clamp Detection<br />
There is an industry-wide issue with<br />
joint failures, caused by incorrectly<br />
aligned electrofusion couplers . This<br />
is most frequently the result of the<br />
improper use of pipe alignment<br />
clamps, or failure to use clamps at all.<br />
Best-practice for operatives is to<br />
use clamps on all occasions and this<br />
is company policy. The Fusion<br />
Department have been working on<br />
the development of an assurance<br />
solution that, whilst not impeding on<br />
operators will prevent or hinder bad<br />
practice, and will furthermore record<br />
occurrences of bad practice.<br />
The system currently under<br />
development uses the electromagnetic<br />
energy emitted by the fitting during<br />
the welding process to enable fitting<br />
detection. Due to the behaviour of<br />
the energy that is sensed, we have<br />
optimised the clamp design to shield<br />
the signal and increase accuracy by<br />
only allowing the fitting to be sensed<br />
from the sides or from above.<br />
This signal must be in a specific axial<br />
arrangement to the clamp and within<br />
its sensing range, typically 6-7 inches.<br />

Standard electrofusion fitting<br />
Magnetic flux generated by the<br />
energised electrofusion fitting<br />
Sensor coil mounted in the base of the<br />
clamp detects when fitting is energised<br />
If this requirement is not met the<br />
unit suspects a bad joint and aborts<br />
the weld.<br />
The unit can be programmed to lock<br />
out if necessary, preventing the<br />
operator from further welding until a<br />
supervisor unlocks the unit. In any<br />
instance the unit will electronically<br />
record clamping activity. This unit is<br />
totally unique within the industry and<br />
has been developed within The Clancy<br />
Group, in co-operation with our<br />
suppliers. We currently have European<br />
patent pending on the design.<br />
The system is currently being<br />
successfully used on the Optimise<br />
VMR, South East Water, Southern<br />
Water and Sutton and East Surrey<br />
Water contracts.<br />
Kobus Pipe Puller<br />
Trials are currently underway on the<br />
Optimise JV of the Kobus Pipe Puller.<br />
The main advantages to this system are::<br />
Excavations over the main can be<br />
relatively small. Minimum risk to<br />
other services; It is a fully trenchless<br />
method; suitable when a mole cannot<br />
be used; 95% success rate; can<br />
replace customers lead pipe without<br />
the need to excavate driveways,<br />
steps etc; it also reduces the<br />
requirement for traffic management.
