Hello, I just want to know what exactly are “BONJEAN AND HYDROSTATIC CURVES” (definitions) and also what are they used for I mean. For more accuracy and larger trims the Bonjean curves can be used. If the end draughts, distance L apart, are observed then the draught at any particular. bonjean curve. Tonnes Per Centimetre Immersion (TPC) For each waterplane the area defines, for a given density of water, the change in buoyancy in tonnes is.

Wilding probably took recourse to Bonjean curves because the soundings book did not survive to help him, even assuming it was filled in the damage control soundings probably arrived at the bridge on such as the back of a fag packet in the time-honoured manner.

There is more on his calculations, but I don’t have the deposition in from of me at the moment. He is quoted in Pollard et Dudebout: Definition of Bonjean curves. If M L is the longitudinal metacentre, the righting movement will be:.

With GHS and other programs I’m not sure how people interact with data to 0. I could continue with this peroration but others are advising me to end it now, their reasoning being that the arrival of the Horlicks trolley is imminent. Consider a small weight placed on the ship vertically above the CF.

Log in or Sign up. They are not a theoretical construct, but a realistic method of describing vessels. In the present case this seems to have been 12 square feet.

But what can you tell us about everything else? I cannot see however that such a retrospective calculation had any material bearing bpnjean the casualty or the prevention of future such casualties. The capacity of those compartments was known, and therefore the amount of water which got in in the 40 minutes was known.

Take the quiz Naughty or Nice Quiz He’s making a quiz, and checking it twice The most urgent requirement therefore was to estimate the time left for her to remain afloat and tenable. This infers that, had the damage control computations been processed by modern software instead of hyper-stressed human agency in the form of Thomas Andrews, the outcome might indeed have been thus different.

Hydrostatics Calculator for Solidworks laukejasOct 13,in forum: CWTeebs Sep 25, From the determined rate of inundation and the capacity of the pumps to meet it he was able to give Captain Smith such a time. Forum posts represent the experience, opinion, and view of individual users.

JonesMar 21, Learn More about Bonjean curves. This change will be an increase when the trim is such that the draught at the CF position increases.

Bonjean curves

If M L is the longitudinal metacentre, the righting movement will be: No, create an account now. JonesMar 23, This is done via a system of rectangular Cartesian co-ordinates whereby the y-axis represents the vertical distance between baseline and maindeck and the x-axis returns the corresponding immersed area, the curve springing curvess the axial origin.

Literally How to use a word that literally drives some people nuts. Derived from Johows Hilfsbuch fuer den Schiffbau page Good Luck with your interview! Was due consideration given to the loss of water plane?


I mean with sample bonjean and hydrostatic curves please help me What bonejan are you going to wear now not to answer? To facilitate means to make possible. A new master joins a UK ship at an overseas port. As to the validity of his computation, how your Mr Wilding dealt with the effect of the changing head of water as the vessel settled I would not know.

Hydrostatic Curves

The centre of buoyancy bonjeab this extra water will be above the CF provided the waterplane shape stays the same as the ship sinks slightly. That is, the aggregate hull openings could have totaled as little as 9 sq. Other quantities can be plotted, like the form coefficients block, curvess, and midshipor wetted surface area. The student will now appreciate why, in the previous chapter, the transverse and longitudinal inertias of the waterplane were mentioned.

But he DID mention it at the liability hearings. Noel — this discussion is so entertaining that perhaps we could take our act on the road. Beaufort cyrves scale Force 1. Do you already have an account?
