The WNA mark ( Winter North Atlantic mark) is required by the ships lesser than 100 mtrs in length trading in North Atlantic Ocean during the Winter Season. During the first conference on the Loadline convention it was generally agreed that the freeboard of small ships should be especially examined with a view to some increase being made ( in freeboard) . Statistics of ship losses had highlighted the safety problems associated with vessels under 300 ft long and some action was necessary. It was recognized that it was difficult for ships lesser than 100 mtrs ( 328 feet) to (more)

Each position circle found using the Sextant Altitude is of immense radius. Therefore, any short length of the arc of some circle can be considered as an straight line . Comparing the observed distance to the celestial body the calculated distance using an estimated position provides the distance towards, or away from the body.. The observed distance is known as the True Zenith Distance (TZD.) The value based on the assumed position is the Calculated Zenith Distance (CZD.) The difference between the two is known as the Intercept. The closest point on this circle is known as the Intercept Terminal (more)

Dipper is used to take out drinking water from the container.... it is graduated so that water quantity can be measured. It is provided with a lanyard so that the water can be taken out from the container without spilling over since once in distress situation you need to save every drop of water!

Resolution A.962(23) IMO Guidelines on ship recycling was adopted on 5th Dec 2003. The guidelines note that, in the process of recycling ships, virtually nothing goes to waste. The concept of a "Green Passport" for ships is included in the guidelines. This document, containing an inventory of all materials potentially hazardous to human health or the environment, used in the construction of a ship, would accompany the ship throughout its working life. Successive owners of the ship would maintain the accuracy of the Green Passport and incorporate into it all relevant design and equipment changes, with the final owner delivering (more)

In event of an oil spill , List of National Contact points and Authorities as stated in your SOPEP manual shall always be contacted. In case the pollution happens in the US waters... the QI ( Qualified Individual ) must be contacted.

Oil tankers have a lesser freeboard than general cargo ships of the same LBP. They are considered to be safer ships for following reasons- 1. They have much smaller openings on the main deck. 2. They have greater subdivision 3. The cargo of oil has generally more buoyancy than the bulk cargo or general cargo 4. They have more pumps to quickly control the water ones in case of an bilging or flooding incident 5. Cargo oil has a permeability off about 5% compared to grain cargo/bulk cargo which has a permeability of about 50-60% 6. Oil tankers have greater (more)

The best and perhaps the only way to reduce the squat is to reduce the vessel’s speed.

The biggest threats here are pollution and fire. 1. Report / Raise the alarm 2.Activate the Emergency shut down devices/ trips 3. Inform loading/receiving trial of the same and ask them to stop pumping in case you are loading cargo 4. Raise the oil containment procedures 5. Follow emergency procedures as per the SOPEP 6. Fire fighting equipment shall be rigged and fire fighting team should be standby 7. Wilden pumps shall be used in order to transfer the oil to the slop tanks 8. In case oil goes over board national Contact points as per the SOPEP shall be (more)
