On-Site Line Boring

On-Site & In-Situ Line Boring

Nicol & Andrew have been line boring main bearing pockets, turbine casings, tail shaft bores, rudder bores and industrial equipment bearing housings for decades.

With our latest Laser guided boring equipment, we can now correct even the slightest misalignment problem on every size and range of diesel engines or marine/industrial plant.

We can machine main bearing pockets and caps on any engine. We can also carry out on-site line boring to engine blocks, propeller housings and ships steering gear.

We work alongside companies involved with power generation, offshore platforms, the marine industry and many others.
