Diesel switch

  • Changeover from preheated HFO to cold MDO/ MGO and vice versa represents a risk of fuel pump sticking or seizure due to the very small clearances in the fuel pump.
  • The Diesel Switch is able to do the changeover in a controlled way so that rapid temperature deviations are avoided. 
  • The changeover between HFO and distillate fuels can give problems for the fuel equipment, the process will need a high degree of automation to avoid incidents. MAN Diesel now offers the Diesel Switch, which ensures the necessary the flexibility and safety when changing between HFO and MDO/MGO.

The principle of the Diesel Switch- 

  • MAN Diesel recommends to reduce the load to 25-40% to control the changeover. 
  • The Diesel Switch ensures a controlled and safe changeover independent of the engine load. 
  • The Diesel Switch operates on a combination of the temperature at the engine and the time.
  •  If the fuel temperature at the engine inlet exceeds 2 degrees/minute the Diesel Switch will give an alarm and put the process on hold.
  •  The process will be logged in the Diesel Switch so that it can be used as documentation to port authorities after the changeover.

The Diesel Switch offers:

  • Touch screen control panel
  • Control handle for the changeover
  • Safety
  • Data logging
  • Changeover valve 
  • Magnetic coupling
  • Integrated sensor for actual position 
  • Integrated sensors for end positions
  • Integrated connection box
  • Manual override 
  • Controlling an MGO cooler or chiller
  • Data logging of temperatures and pressures 
  • Remote operation with second touch screen

    I'm truly intrigued with your composing aptitudes and furthermore with the design on your weblog. Is this a paid subject or did you adjust it yourself? Whichever way keep up the decent quality composition, it is uncommon to see a pleasant blog like this one nowadays. Magnetic coupling

Main engine interlocks

Interlocks are provided so that the engine can be started or reversed only when certain conditions have been fulfilled. When there is a remote control of engines, it is essential to have interlocks. This reduces the possibility of engine damage and any hazards to the operating personnel. Turning gear Interlock . This device prevents the engine from being started if the Turning gear is engaged. Running Direction Interlock . This prevents the fuel from being supplied if the running direction of the engine does not match the Telegraph. Starting Air Distributor in end position . This prevents starting from taking place if the shifting of the Distributor has not been completed. Main Lube. oil pressure, Piston cooling pressure, Jacket water pressure, and important parameters must be above the required minimum. Auxiliary Blower Interlock . The Auxiliary Blower is provided in case of Constant pressure turbo charging. Air Spring pressure Interlock . In case of the present generation...

Differences between MC/MC-C and ME/ME-C engines

The electrohydraulic control mechanisms of the ME engine replace the following components of the conventional MC engine: Chain drive for camshaft Camshaft with fuel cams, exhaust cams and indicator cams Fuel pump actuating gear, including roller guides and reversing mechanism Conventional fuel pressure booster and VIT system Exhaust valve actuating gear and roller guides Engine driven starting air distributor Electronic governor with actuator Regulating shaft Engine side control console Mechanical cylinder lubricators. The Engine Control System of the ME engine comprises: Control units Hydraulic power supply unit Hydraulic cylinder units, including: Electronically controlled fuel injection, and Electronically controlled exhaust valve activation Electronically controlled starting air valves Electronically controlled auxiliary blowers Integrated electronic governor functions Tacho system Electronically controlled Alpha lubricators

Shell Expansion Plan

It is a two dimensional drawing of a three dimensional surface of the ship’s hull form. This plan is very useful for the following information:It is used for marking the location of a hull Damage on this plan by identifying the strake number , letter and frame number so that the exact location of the damage and also suggested repairs are marked in a localised copy. The shell expansion can be used for finding areas of painting surfaces such as topside, boot topping and bottom areas by applying Simpsons rules directly.  In the shell expansion the vertical scale used is different from the horizontal scale and a suitable adjustment has to be made when calculating areas. This becomes useful in solving disputes concerning areas of preparation and painting. It gives information on the thickness of the original strake which is indicated by the number in the circle shown in the strake.  The quality of steel used is also shown by letters A,B,D E and AH, BH,DH, EH.
