Consultant to Linear Composites Ltd (manufacturers of Parafil ropes),
to give specialist advice on civil and structural engineering uses for their
high strength ropes. As part of that work I have given advice, either to
Linear Composites Ltd or to the designers, or both, relating to several

or mooring lines. These include:-
Repair of heavily cracked Power Station Cooling Towers by circumferential
prestressing.
The design and installation of cable stays for the roof of a Bus
Station in Cambridge.
The design of the stay cables for the Aberfeldy Bridge.
The use of prestressing cables in a prestressed brickwork bridge
at Tring.
The use of prestressed tie cables for a footbridge in Norway.
The use of aramid ropes for 52m version of the Medium Girder Bridge
for military use.
Advised on marine applications of ropes for US Navy and other offshore
uses.
