  Assume you are instructed to submit to superintendent engineer a complete set of indicator cards together with relevant data. Give full account of your work in taking the cards and preparing them for submission.   * Indicator cards are used to determine compression pressure, peak pressure and engine power. They should be taken on a regular basis as they are vital for assessing whether any adjustments to the fuel timing are required. They also determine the condition of the cylinders. * Traditionally, indicator cards were taken using a mechanical indicator fitted to the cylinder indicator cock. This method is still in use today, however, more and more vessels are now equipped with electronic engine performance monitors. These monitors, as well as having sensors fitted to the indicator cocks, also monitor shaft rpm, scavenge air pressure and fuel pump pressure etc. * There are essentially two types of indicator card –...

To                                                                                                          Date: -DD.MM.YY Technical Superintendent XYZ Shipping Let Germany,   Sub: Aft end vibration and Suggested remedies, From Second engineer M.T. Front Scilla   Ref: - Your letter dated on – 23.09.2012   Dear Sir,   This is in connection with the mentioned letter regarding the “Severe aft end Vibration” Now let me furnish the related observations, findings and possible remedies for your kind perusal and our future course of action.   INVESTIGATION: 1. Engine performance has been taken. Load found to be equally distributed among all the cylinders i.e. there is no power imbalance 2. Crank shaft deflection has been taken all units crankshaft deflection readings are within the maker’s specified values 3. Engine all units main, crankpin and cross head bearing and also thrust bearing clearance taken and found within normal limit. 4. Main Engine all parameters are within limit. 5. Work done History of engine is checked to...

Gentlemen,  One of the recent topics of discussion among Surveyors is regarding the Capuccino Bunkers and measures to prevent such practices. One of the answers which was accepted by Surveyors is: i) Capuccino Bunkers will be indicated by fluctuating pressure gauge at Bunker Manifold, High rate of air venting out from Bunker tank vents & the sounding tape having bubbles on the tape. If suspected; ii) stop bunkering in one of the tanks, Take proper precautions (Permit for cold work; Permits for opening manhole doors etc., as per each company's SMS requirements) and open the tank manhole door. If the surface of the FO in the tank is found frothed, it is suspected to be a case of Capuccino Bunker. iii) Inform the Barge, Take Photographic proof, Get it signed by the Barge master; in the BDN- on final figures, write down as "subject to final quantity check after two days"....

Ex NCL ship Norwegian Dream (1992).  Purposely refitted in dry dock to sail Baltic Cruises from Dover through Kiel Canal.  Both funnel and forward mast were hinged and could be lowered to pass under the Bridge in the Kiel Canal.   KIEL CANAL The Kiel Canal, artificial waterway in north-western Germany, linking the North Sea and the Baltic Sea.  The canal extends in a north-eastern direction across the state of Schleswig-Holstein from Brunsbüttelkoog, near the mouth of the Elbe River, to Kiel, on the Baltic. The canal is very level, and has locks only at its ends to accommodate North and Baltic sea tides. Constructed between 1887 and 1895 and subsequently enlarged, the canal is about 97 km (60 mi) long, 102 m (335 ft) wide, and 11 m (36 ft) deep. The canal shortened the distance between the North and Baltic seas by about 322 km (200 mi) and eliminated...

NUCLEONS

Posted by on in Engineering - Technical
NUCLEONS The nucleus is made up of protons and neutrons, collectively known as nucleons. These are fermions (spin-half particles) of almost the same mass (in fact it is often useful to think of them as two different states of the same particle, distinguished by different values of quantum number, isospin). Basic properties are given in Table 1. Nucleons interact with one another via a strong nuclear force (the protons also interact via the electromagnetic force). The origins of this force lie in the interactions between quarks, and the ``force law'' is only approximately known. At the level of nuclear physics, it can be viewed as resulting from the interchange of various mesons between the nucleons. The most important of these are the pi mesons The force is strongly spin-dependent, i.e. the force depends on the orientations of the intrinsic spins of the two nucleons. An important component is the tensor force,...
