Inspection of Auxiliary Engine Crankcase

• If the Generator has been running, allow it to cool down before
opening the crank case doors.

• Check the visual condition of crank case walls and the crankshaft and lube Oil. If the crank case and the oil is black, it means that there is blow past of some units.

• Pump out the crank case oil in a drum or whatever arrangements
are provided.

• Test the oil with the lube oil testing kit provided on board.

• Look for any signs of jacket cooling water leakage in crank case. In doubt, pressure test the system by connecting a hydraulic pump
to the inlet of the cooling water and keeping the outlet from the
engine shut.

• Look for any signs of wiped bearings.

• Check the tightness of Main bearing bolts, Crank pin bearing bolts and ensure that all the lube oil connection pipes in the crank case are tight.

• Check that the crank pin bearing is floating on the pin.i.e. you should be able to move the crank pin bearing side ways with the help of a crow bar.

• Check and clean the lube oil suction filter if provided inside the crank case.

• Start Lub. oil pump or pump oil with the help of the hand pump. Turn the engine slowly. Check in each unit, that the oil is freely flowing out of from crank pin bearing, main bearing, and Gudgeon pin bushes both sides.

• Check and clean Cyclone oil filter if provided.

• Renew crank case oil if required. In case the oil is being renewed
due to contamination, first take little oil in the sump, open the drain provided on oil cooler, and flush out the old oil remaining in the pipe line and the cooler. Close the drain and take oil in the sump.

• Check the crank case door jointing. Renew if damaged.

Load Line & Why it is Important

Merchant ships have a marking on their hull know as the Plimsoll line or the Plimsoll mark, which indicates the limit until which ships can be loaded with enough cargo, internationally, the Plimsoll line on a ship is officially referred to as the international load line. Every type of ship has a different level of floating and the Plimsoll line on a ship generally varies from one vessel to another.  All vessels of 24 meters and more are required to have this Load line marking at the centre position of the length of summer load water line. There are two types of Load line markings:- Standard Load Line marking – This is applicable to all types of vessels. Timber Load Line Markings – This is applicable to vessels carrying timber cargo. These marks shall be punched on the surface of the hull making it visible even if the ship side paint fades out. The marks shall again be painted with white or yellow colour on a dark background/black on a light background.  The comp

Difference Between A, B & C-Class Divisions?

IMO Symbol A Class Division  IMO Symbol B Class Division  SOLAS has tables for structural fire protection requirement of bulkheads and decks. The requirements depend on the spaces in question and are different for passenger ships and cargo ships. The Administration has required a test of a prototype bulkhead or deck in accordance with the Fire Test Procedures Code to ensure that it meets the above requirements for integrity and temperature rise. Types of Divisions: "A" Class "B" Class "C" Class "A" Class: "A" class divisions are those divisions formed by bulkheads and decks which comply with the following criteria: They are constructed of steel or equivalent material They are suitably stiffened They are constructed as to be capable of preventing the passage of smoke and flame to the end of the one-hour standard fire test. they are insulated with approved non-combustible materials such that the average tempera

Pump Shaft Alignment Procedure

Types of shaft alignment methods: Visual Line-Up Straightedge/Feeler Gauge Rim and Face Cross Dial Reverse Dial Laser Visual Line-Up The visual line-up method is the most common method of alignment. Used in initial installations, visual line-up allows technicians to analyze the working conditions and feasibility of installation. Straightedge/Feeler Gauge Straightedges are used to determine the offset between coupling halves. Corrections are made under all four of the machines feet. Feeler gauges or taper gauges measure the gap between coupling halves at the bottom and top of the coupling. Rim and Face This method is similar in principle to using a straightedge and feeler gauge, but more accurate since dial indicators are used. The rim reading measures the offset between the coupling halves. The face reading measures the angular difference between the faces of the coupling. Changes are calculated with the same formula as the straightedge/feeler gauge met
