With over 25 years of extensive field experience worldwide, On Site Alignment is the expert when it comes to any alignment problem. The correct alignment of all elements of a propulsion system is vital. Preventing a breakdown of machinery is always the better option.

Alignment checks whether measurements can be performed during different states of operational conditions so that thermal growth and hull deformation are measured too. This is also true for the actual alignment.

THE OSA ALIGNMENT MEASURING TECHNIQUES

There are many ways to measure. For them, however, there is only one way: the right way, where they use different high-quality techniques for different applications. Every specific machine demands a specific alignment technique. First, they must determine the appropriate one. On Site Alignment knows and uses all known techniques.

• Feeler gauges, rulers and dial indicators are used when shaft rotation is difficult or non-existent.
• Laser equipment is used for rotating equipment, line bore and geometric measurements.
• Wireless torque measurement is used for measuring shaft power.

• They use electronic measurement of bearing reaction forces for accessible stern tube bearings, shaft support bearings, gearbox bearings and main engine bearings.
• (Wireless) strain gauge bending stress measurement is used to calculate bearing load and offset, the jack load and gap and sag values in propeller shafts and high speed shafts.

They determine the best option in close partnership with the customers.
