1. General
Hydraulic transverse stays are used to shift the natural frequency when resonance can be expected in the normal operating range of the engine.

The applied arrangement enables :
- The adjustability of the pretension force.
- The adaptability to the slow movement of the ship's hull when loading or unloading the ship.

2. Description
The hydraulic lateral fixation device consists of :
- Hydraulic cylinder with differential piston, fitted with hydro accumulator and pressure gauge.
- Stays for lateral fixation of the engine to the ship's structure.
- Adjusting screw, fixed to the engine.

Accessories per ship for single main engine installation
(for multiple main engine installation the engine supplier is to be consulted)

- Hydraulic cylinders either to design 200 or 201 with adjusting screw
Design 200 : Compact execution
Design 201 : Hydro accumulator detached for separate installation (Fittings included, but connection
steel pipe Ø10 x 2 is yard delivery)

- Tester and pressurizer for nitrogen
