Diamond Wire sawing of offshore barge

WIRE SAWING OF OFFSHORE BARGE

In February 2009, UKdima Engineering Ltd was commissioned by John McMullan of McMullan Sea Services, Glenariffe, Co. Antrim to separate his offshore barge the Sgt Pepper, by utilising diamond wire sawing techniques. The aim was to allow the boat to be stretched by 3m. Cutting a steel hulled vessel using this method had never been attempted before in Ireland. Diamond wire sawing was chosen as a method above any other technique (ie. hot works) to give the fabricators a clean cut to work on and to avoid distortion and hardening of the work piece.

UKdima Engineering Ltd supplied the wire saw and world patented electro-plated diamond wire for cutting solid steel, as well as the cutting method, labour and expertise to carry out the job. The size of the barge was a depth of 3m and width of 6m. Due to the space constraints of the slipway, the wire saw had to be located on the deck of the barge and the wire was pulled up through the boat. One 25m length of wire was used to successfully complete the job in just 10 hours in one single cut, with no wire breakages.
