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.

Diesel Engine Bedplates

Damaged diesel engine bedplates and entablatures are routinely repaired by our experienced technicians after a catastrophic failure, saving the need for costly replacement. On-site diesel engine repairs can be carried out at sea, alongside or in a dry dock or a power generation plant around the world, by way of Nicol & Andrews precision Line Boring systems.

Coupling Bolt Holes

Flange couplings are a critical part of a rotating machine for power transmission. Coupling flange joint is achieved by calibrated bolts working on shear stress. For this reason, it is important to perform machining on each hole on both flanges together, to get a perfect result in terms of co-axiality, diameter precision and roughness. This process is carried out by special low clearance boring machine..
