Registan - Trial

TRIAL TRIP OF THE s.s. REGISTAN

Northern Daily mail June/18/10

Yesterday, the large steel screw steamer Registan, built by Messrs. William Gray and Co., Ltd., for Messrs. Frank C. Strick and Co., Ltd., of London, had her trial trip. A description of the vessel has already appeared in the “Mail”

Triple-expansion engines have been supplied by the Central Marine Engineering Works of the builders, having cylinders 25in., 40in., and 65in. diameter by 42in. stroke, and two large steel boilers of the builders well-known flanged shell type, adapted for a pressure of 180lbs. per square inch, worked under Howden’s system of forced draught. The portings in the cylinders are large to insure an easy passage for the steam, and so obtain the maximum efficiency from it.

The engines have been fitted with a “contraflo” main condenser a “contraflo” atmospheric type condenser being installed for the auxiliary machinery. A Weir’s feed pump and heater, a Morrison’s surface feed heater, combined with oil and air extractor, are 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.
 
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 performance of ship and machinery was  very satisfactory, a speed of 13.1 knots being obtained. Mr. Archibald Walker, who has superintended the construction of the ship, represented the owners on the trial; Mr. James Innes, Lloyd’s Register; Captain J. E. Murrell, the shipbuilders; and Mr. J. B. Williams, the engine builders.
