Man Overboard

In the event of a Man Overboard:
  • Shout ‘man overboard’ to alert the crew.
  • Press the MOB button on the GPS.
  • Throw a life buoy and dan buoy to the MOB. Mark the MOB with a buoyant smoke flare.
  • Allocate a crewmember to point at the MOB in the water.
  • Send a DSC distress alert and a Mayday.
  • Keep pointing; don’t lose sight of the MOB.
  • If the motor has been started,
  • Prepare a throwing line.
  • The skipper will bring the boat alongside the MOB, with the boat pointing into the wind and the propeller stopped.
  • Get a line around the MOB and get them aboard.
Light and Smoke Lifebuoy Marker produces dense orange smoke for 15 minutes and features two self contained, inversion switched, LED lights which far exceed SOLAS requirements for output and duration.
Ships are required to carry 2 markers, one mounted on each bridge wing with the brackets supplied and attached by line to a 4kg Lifebuoy.
The signal is used to mark the position of a man overboard by day or night.
It can be automatically deployed by releasing the attached lifebuoy, or manually activated.

MOB drill requirements
1.7.1 SOLAS does not specify the frequency of the MOB drill to be conducted, but such a drill should ensure that crew are familiar with the plans, 
procedures and equipment for recovery of persons from the water. 
According to the flag State, the company is responsible for identifying
potential emergency shipboard situations and establish programmes for 
drills and exercises in the SMS28 to prepare for such emergency situations.
1.7.2 MOB drill was to be conducted once every 6-months as per the company’s 
SMS procedures.

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

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...

Why is a man hole door elliptical in shape?

Any opening in a pressure vessel is kept to a minimum and for a man entry an elliptical hole  is lesser in size than the corresponding circular hole. More over it is prime concern to have a  smoothed generous radius at the corners to eliminate stress concentration. Hence other  geometrical shapes like rectangle and square are ruled out.  To compensate for the loss of material in the shell due to opening, a doubler ring has to be  provided around the opening. The thickness of the ring depends on the axis length along the  dirrection in which the stresses are maximum and the thickness of the shell. It is important to  align the minor axis along the length of the vessel, as the stress in this direction is  maximum. Longitudinal stress: Pd/2t where P= pressure inside the vessel, d= diameter of the arc, t=  thickness of the shell plating  Circumferential stress: Pd/4t  More over a considerable material and weight saving is achieved as...
