Hinkley Point power station wire sawing project

Published 9/3 at 15:46

Drillcut began 2021 by embarking on a large wire sawing project at the renowned Hinkley Point nuclear power station.

A staggering 234m of capping beam had to be taken off the sea defence wall in under four months. To add to the complexity of the job, all the work had to be carried out from mobile access platforms. With 310m² of wire sawing to be done, it was crucial Drillcut used the best performing wire for the project. After a few tests, the company wisely chose Dymatec’s SDF W Diamond Wire. This is a 10.5mm sintered premium wire designed for heavily reinforced concrete. Consistently cutting over 2m²/h it kept the Drillcut team on track, with this type of cutting speed being normally compromised by short lifetime. However, with the SDF W Diamond wire, there was no need to worry as it returned cutting figures of over 1.55m² per linear metre of wire.

Drillcut’s director, Harry Goodfield, said: “With so much at stake on this project we had to throw everything at it from the word go. We put our best teams on it; Dymatec came up with this outstanding wire and we managed to deliver the project ahead of schedule.” An impressive number of 78 x 20t lumps were lifted onto trucks and taken off site successfully, with the only delays being caused by the occasional coastal storm which put the cranes out of action. 200m of SDF W Diamond Wire were used on the project to complete the 351 cuts with three wire saws.
