 |  | Fitting Bolts |
With special cutting tools, damaged fitting bolts can be drilled out without damage the bolt seat.
For example:
- flange joints of propulsion plants
- ragged studs on main engines
- Etc.
 |  | Ships Main Engines |
In situ line boring on ships main and auxiliary engines is needed in following areas:
- Line boring of main bearings in bed plates
- Machining cylinder liner seats on engine blocks (for bushes in the lower area and L- or Z - rings in the upper area, as well as cylinder liner landing faces)
- Drilling out of ragged studs on main engines
- Etc.
 |  | Stern Tubes |
- line boring of stern tube and supporting bearing (A- and I-frames) seats for propulsion plants
A specifically of T&D developed laser alignment method with laser systems, into combination with boring bars, ensures a perfect axis situation of the drive shaft bearings.
A complete documentation gives our customers safety, because unnecessary operating failures are a thing of the past after using our alignment method.
