precautions involved in running with Sulzer RT flex

1.   What are the precautions involved in running with RT flex

    Reliability and safety has the utmost priority in the common rail RT-flex system.

v  The duplicated high-pressure delivery pipes have stop cocks at both ends to isolate any failed pipe. Each single pipe is adequate for the full delivery. All high pressure pipes are double-walled for safety.

v  Every injection nozzle is independently monitored and controlled by the WECS. In case of difficulties, such as a broken high pressure line or a malfunctioning injector, the affected injection valve can be cut out individually without losing the entire cylinder.

v  If the stroke measuring sensor fails, the WECS system switches the ICU to a pure time control and triggers the signal based on the timing of the neighbouring cylinders.

What is the Rocking Test?

It is a test which is carried out to find, wear down of the
sleeve bearing of the deck crane on ships.

this measures the play (or relative movement) between the inner 
 and outer bearing race, to give an indication of the wear taking place.

(Wear down of the sleeve bearing can be found by analysing the grease sample.
The metal content  of the sample may give indication of wear down.)

The Rocking Test need to be carried out according to manufacturer 
recommendation

Measurements are typically taken in four positions on 
the slew bearing, with the jib pointing:

• forward to the ship
• starboard
• aft 
• port side.

Neither a load nor any cargo handling equipment should be attached to the hook.
It is important for the same positions to be marked as a datum reference.. 

What is the TMON?

TMON is the Tail shaft Monitering.

advantages as follows.

Purpose

To offer operators the opportunity to avoid withdrawing the tail shaft if indications show that the tail shaft and stern tube bearing and its systems are working satisfactorily.

Benefits

1. Avoids time-consuming operations during dry docking
2. Avoids the risk of damaging to the system during withdrawal
3. Reduces costs
4. Achieves an opportunity to monitor that the condition of the stern tube bearing and tail shaft are in good condition due to the system being followed up. When the system is properly implemented, the crew will be able to foresee possible damage and take preventive action

Features

This class notation is applicable to conventional propulsion systems. Tail shaft monitoring implies monitoring of the stern tube bearing, water content of the lub oil and litre lub oil refilled:

• The stern tube bearings are oil lubricated.
• A high-temperature alarm is fitted on the aft stern tube bearing.
• Where one interchangeable sensor is fitted, one spare sensor is to be stored on board.
• The setting of the stern tube high-temperature alarm should not exceed 65°C.
• The sealing rings in the stern tube sealing box must be replaceable without having to withdraw the shaft or remove the propeller.
• A system for measuring bearing wear must be fitted.
• Electrical grounding of the shafting is mandatory.
• The system must allow representative oil samples to be taken for an analysis of the oil quality under running conditions.

A written procedure for how to take oil samples is to be evaluated.

TMON gives the owner the opportunity to leave the tail shaft in position without pulling it out of the stern tube provided:

1. The technical requirements are met.
2. The TMON Record File is kept updated.
3. Oil samples are regularly analysed and found to be satisfactory by a recognised laboratory.
4. All stern tube bearing temperature values are within the manufacturer's recommended or limit values.

Reasons to fail the Tie Rods

1. Uneven  and not properly tight the tie rods.

2. Material failure.

3. Scavange fires

4. Over tight of the tie rods

5. Secondary forces are not properly balanced

6. Fluctuation of thermal load and compression loads due
    to bad weather or malfunction of fuel oil system.

What are the purposes of Tie Rods

1. It holds cylinder block, A frame and bed plate together

2. Transfer the firing and compression pressures (tensile  stresses) to the bed plate.

3.The tensile stresses which creating  during compression and firing may cause fatigue failure
    of engine component, which eliminate by the tie rods.

3. Because of  it fitted close to crank shaft, prevent bending of transverse girders.
