Page 75 - I never embarked on any one thing to which I have so entirely devoted myself and to which I have devoted so much time, thought, and labour; on the success of which I have staked so much reputation, and to which I have so largely committed myself and those who were supposed to place faith in me.
Page 75 - ... the design of propelling machinery and boilers, with a view to economy of coal and great endurance for long-distance steaming ; the selection of forms and dimensions likely to minimise resistance and favour good behaviour at sea ; and to other features of the design which need not be specified, Brunei displayed a knowledge of principles such as no other ship-designer of that time seems to have possessed, and in most of these features his intentions were realised. To him large dimensions caused...
Page 81 - ... expended in evolving gas at the cathode ; and finally, the repeated operation of ' scratching,' removes some of the deposit. Allowing for all these, and other unavoidable sources of loss, in practical working, about one pound only of copper, can be deposited in the ordinary sulphate solution, by the consumption of from one and a quarter to one and a half pounds of zinc, and an equivalent quantity of acid, in each alternation of the battery. With regard to regulation of the speed of deposition,...
Page 76 - Steam for these engines was supplied by four, double-ended, tubular boilers, each 17 feet 9 inches long, 17 feet 6 inches wide, and 13 feet 9 inches high, and weighing, with water, 95 tons.
Page 75 - Brunel's notes and reports, my admiration for the remarkable grasp and foresight therein displayed has been greatly increased. In regard to the provision of ample structural strength with a minimum of weight, the increase of safety by watertight subdivision and cellular double bottom, the design of...
Page 62 - The watertight deck referred to is called the bulkhead deck. The line past which the vessel may not sink is called the margin of safety line. "The margin of safety line, as defined in the above report, is a line drawn round the side at a distance amidships of three-onehundredths of the depth at side at that place below the bulkhead deck, and gradually approaching it toward the aft end, where it may be three-two-hundredths of the same depth below it.
Page 90 - These and other features involve additional weight; and the Great Eastern has the advantage of being deeper in relation to her length than the modern ships. After making full allowance for these differences, my conclusion is that the Great Eastern was a relatively lighter structure, although at the time she was built only iron plates of very moderate size were available.
Page 90 - I have most thoroughly investigated the question of the weight absorbed in the structure of the ' Great Eastern : and my conclusion is that it is considerably less than that of steel-built ships of approximately the same dimensions and of the most recent construction. Of course these vessels are much faster, have more powerful engines, and have superstructures for passenger accommodation towering above the true upper decks which form the upper flanges of the girders. These and other features I cannot...
Page 76 - The following are some of the principal dimensions and other data of the Great Eastern : — Length between perpendiculars . . . . . . 680 feet. Length on upper deck . . . . . . . . 692 Extreme breadth of hull . . . . . . . . 83 Width over paddle-box...
Page v - Nobody, not even the shipbuilders themselves, seemed to realise what was being done, until, suddenly, the world's finest vessel, in all the pride of her maiden voyage, struck an iceberg and went to the bottom in something over two and a half hours...
