50 Vs M/s SECUNDO’ -Q"+53-G » 27-6 « 35-G At 4 ~ =iSS sro steee sy Lewes Arrangements throughout the ves- sel are in accordance with latest prac- tice. Large refrigerated provision rooms and an ice making machine are provided. Electric light is installed throughout and a water as well as a steam fire-extinguishing system is fitted according to the requirements of the Norwegian laws. An oil fired donkey boiler of the cross tube type placed in the engine room supplies the steam for heating the quarters. Diesel Propelling Machinery The propelling machinery consists of two 6-cylinder, four-cycle single act- ing and forced lubricated diesel en- gines of Burmeister & Wain’s new light-built type for twin screw vessels. The main particulars of the en- gines are as follows: Cycle operation, strokes .......... 4 Number of cylinders ................. 6 Revolution per minute ................ 150 Indicated horsepower ..............006 2300 Sea speed in knots .................s0000 10% The daily fuel oil consumption per 24 hours is about six tons giving the vessel a cruising radius of about 50,- 000 miles. All the auxiliary machinery in the engine room, as well as the deck ma- chinery, is electrically driven. The current is supplied by three dynamos, two of 33 kilowatts and one of 66 kilowatts driven respectively by two single cylindered and one_ twin-cyl- indered auxiliary Diesel engines de- signed and constructed by Burmeister & Wain. The voltage for power is 220 volts, and for lighting this is transformed down to 110 volts’ by means of a rotary transformer. Any one of the dynamos is sufficient to supply the current required for nor- mal working at sea, while only two are needed in operation with all the winches working at full power. The trial trip of M. S. SEGUNDO was run on Sept. 5, 1925 in the Sound of Copenhagen, and over the measured mile the following results were ob- tained under difficult weather condi- tions: Indicated horsepower ..................

The M. S. SEGUNDO is in- tended for service between North and South America. Tanker British Petrol Single Screw Diesel The single screw motor tank ship BRITISH PATROL was built and engined by Swan, Hunter & Wigham Richard- son Ltd. at their Neptune works, Newcastle-on-Tyne, to the order of the British Tanker Co. Ltd. of London. The vessel was constructed for the carriage of oil in bulk. She is 454 feet in length by 57 feet beam and was built to the highest class in Lloyds register. She will carry about 10,100 tons total deadweight on a draft of 26 feet 8 inches. The oil cargo is carried in 20 hold tanks and 10 summer tanks. There is also a hold forward in which ordinary cargo can be carried. The installation for dealing with the oil cargo is very complete, including two cargo oil pumps, each discharging 300 tons per hour, in the main pump room, and a smaller pump room forward, contain- ing the ballast pump and oil fuel pump. The oil fuel for the engines is car- ried in a cross bunker, in the double bottom both forward and aft, and in settling tanks, their total capacity be- ing 740 tons. Can Accommodate Eight Passengers Accommodation is fitted amidships for captain, officers and passengers. The captain’s sitting room, bedroom and bathroom are arranged on the upper bridge, and in the same house are the rooms for the wireless opera- tors. On the flying bridge above this house are situated the chartroom and Marconi room, the flying bridge being protected by teak sheathing and fitted with two clear view screens for the safe navigation of the vessel. A large dining saloon is fitted on the bridge deck and near it on the same deck are a smoking room, state- rooms for the deck officers, four rooms fitted up for the accommodation of +.-- --rh Siueuseskae > i | YY fia R ae a, 'tsgers 7 4 (Bawcnnae yon een ee rae ' ' May, 1926 oc lad eight passengers, and bathrooms. On the poop deck aft there is excellent accommodation for the engineer offi- cers, including messroom, staterooms and bathrooms. On the upper deck forward are rooms for the seamen and firemen with separate dining rooms, while amidships are placed various stores, a hospital and a carpenter’s shop. Aft are rooms for waiters, electricians, cooks, and apprentices. The propelling machinery consists of a single screw set of Swan, Hunter & Wigham Richardson’s internal com- bustion engines of the Neptune two- cycle, single-acting port scavenging type, which have proved their relia- bility. under severe sea-goiny condi- tions. There are eight cylinders, each 24 inches in diameter by 50 inches stroke, the total power being 3200 brake horsepower. In the Neptune oil engine the build- ers have paid every attention to sim- plicity of design and accessibility of all parts. The whole engine can be operated by one man from the con- trol station on the lower platform. Among the most noticeable features of the design, mention should be made of the scavenging pumps placed at the back of the engine and driven by means of levers from the engine cross- heads. The circulating water pumps, bilge pumps and the lubricating pump are similarly driven. The built-up crankshaft, the main bearings, cross- heads and pistons have all been de- signed with a view to obtaining the most efficient lubrication possible and easy accessibility. Two marine type steam boilers are installed, these being necessitated by the steam cargo oil pumps and cer- tain of the engine room auxiliaries which are steam driven. The steering gear is electrically driven, as also are those engine room auxiliaries con- tinually in use at sea, so that the ship may be independent of steam for propulsive purposes. Electric power is supplied by two 60 kilowatt gener- ators of Vickers make, driven by two 90 brake horsepower engines. .
