What is a mechanism that can create water craft to become unstable and…..?

Free surface effect

What is the minimum initial transverse metacentric height?

0.15m

Which statement means the increase in KG is affected by?

Which correction is parallel with the….corrections with the same patterns?

The mid-ship correction

What correction rule is to be used if the vessel is trim by the stern (aft)?

Fore correction should be minus

Your vessel is damaged with the list, but down by the stern. There is progressive flooding and trim by the stern. What is the effect on transverse stability after the deck edge at the stern is submerged?

BM, decreases rapidly due to loss of water plane area

25.87 inches

What is the tendency of the vessel to return to its original trim after being inclined by an outside force?

Longitudinal stability

What correction to be use when the vessel is trim by head (stern)?

Aft correction plus

What will be the result if the aft draft is subtracted from the FWD draft?

Apparent trim

What is the right angle line to the keel passing through the rudder post?

The after perpendicular

What is ship specific onboard equipment and the results of the calculations are only applicable to the ship for which it has been approved?

Ship’s loading instrument

What is a measurement the weight of water a ship displaces of when fully loaded and submerged to her load lines?

Designated displacement

How many percent draft marks or load lines allow a ship’s displacement to be determined to an accuracy?

0.5 percent

What is the weight of the ship including cargo, passenger, fuel, water, stores, dunnage and such other items necessary for use on a voyage?

Loaded displacement

What is defined as the displacement of a vessel when floating at its greatest allowable draft as established by classification societies?

Full load

What is the measure to reduce hogging stresses?

Shift liquids toward midships

Which stress increase during damage and consequent flooding in the middle length?

Increase sagging stresses

When taking on ballast waters, the date and time of commencement and completion of the ballast operation, ship’s position, salinity (specific gravity) and amount of ballast water taken onboard must be recorded in the ship’s________.

Deck log book

Who is designated to carry out these procedures and maintain all records as required?

Chief Officer

What document describes the loading conditions on which the design of the ship has been based, including, permissible limits of still water bending moment and shear force?

Loading manual

What is an essential part of the loading instrument and should be kept onboard at all times?

Operation manual

What may result onboard ship due to internal forces resulting from structural weight, cargo and machinery weight?

Static forces

What forces may result from the ship’s motion at sea, the action of wind and waves and the effects of operating the machinery?

Dynamic forces

What is the greatest stress set in the ship as a whole due to the distribution of load along the ship?

Longitudinal bending

What is refers to the tendency of steel hull plating to flex in and out like an oil can being squeezed when a ship is pitching?

Panting

What instrument the classification society requires a ship to carry an approved means of calculating forces that affect ships?

Calculating shear forces

What is the other name of the calculating equipment onboard ship?

Loadicator

A ship of 9,000t displacement has KM = 8.5m, and KG = 7.6m, and is floating upright. A weight of 60 tonnes already on board is shifted 18m transversely. Find the resultant list. Show all solution.

7.59′ or 7° 35'44"

A ship of 9,500 tonnes displacement has a GM = 0.8m. A quantity of grain in the hold, estimated at 90 tonnes, shifts and, and as a result, the centre of gravity of this grain moves 7.5m, horizontally and 1.5m, vertically. Find the resultant list. Show all solution.

8.77° or 8° 46' 21"

A vessel has a displacement of 18500t, KM = 9.50, KG = 8.6m, she has the following tanks slack. Find FINAL FSM and GM. Show all solution.

0.769m
