Triple-expansion engines are being supplied by the Central Marine Engineering Works of the builders, having cylinders 24in., 36in., and 64in. Diameter, with a piston stroke of 42in., and two large steel boilers for a working pressure of 180lbs. per square inch worked under Howden’s system of forced draught.

TRIAL TRIP OF THE s.s. DJERISSA

Daily mail ****/**/10

Yesterday, the handsome steel screw steamer Djerissa built  by Messrs. William Gray and Co., Ltd., to the order of Messrs. Frank C. Strick and Co., Ltd., of London and Swansea, for La Tunisienne Steam Navigation Co,. of Paris, was taken for her trial trip.

The vessel takes Lloyd’s highest class, and is of the following dimensions, viz.: Length over all, 362ft., breadth, 50ft., and depth, 25ft. 11 ½ in. She has long bridge and poop, and top-gallant forecastle.

The saloon, staterooms, captain’s and officers’ rooms are fitted up in the poop and the engineers rooms in houses on the bridge deck, the crew’s berths being in the forecastle.
The hull is built with deep bulb-angle frames, cellular double bottom, and large aft peak ballast tank. Ten steam winches, steam steering gear amidships, hand screw gear aft, patent direct steam windlass, large horizontal multitubular donkey boiler, stockless anchors, telescopic masts fore and aft rig, boats on deck overhead and all requirements for a first class cargo steamer, including Porter’s patent derrick sockets for dealing with heavy lifts by combining the ships ordinary derricks, have been fitted.

Triple-expansion engines are being supplied by the Central Marine Engineering Works of the builders, having cylinders 24in., 36in., and 64in. Diameter, with a piston stroke of 42in., and two large steel boilers for a working pressure of 180lbs. per square inch worked under Howden’s system of forced draught.

The engines have been fitted with a “contraflo” atmospheric type condenser being installed for the auxiliary machinery. A Morrison surface feed heater combined with oil and air extractor, is also fitted, the engine room auxiliaries, including a number of duplex pumps of the builders “Cmew” type, being very complete and carried out in accordance with the requirement of the owners’ superintendent engineer. On the trial trip a vacuum of 28 ½ inches was maintained with the barometer at 29.9 inches, the whole of the machinery working most satisfactorily. The leading feature of the condenser design is a new method of temperature regulation by means of which the air withdrawing capacity of the air pump can be so adjusted to the demand that the thermal efficiency of the engines is at  a maximum under all conditions of working, this arrangement having a favourable influence on economy.

The ship and machinery been constructed under the superintendence of Mr. Archibald Walker, and that gentleman represented the owners on the trial; there were also present Mr. Robert Bruce, of London, and Mr. James Innes, of Lloyd’s Registry, West Hartlepool. Captain J. E. Murrell represented the builders of the ship and Mr. Maurice S. Gibb the builders of the machinery. A speed of 11 ½ knots was obtained, the performance of both ship and machinery being entirely satisfactory.
