New British India Boat.
This is the first ship built in Great Britain in which this system of scavenging has been used. It results in a very easy regulation of the scavenging air pressure, a considerable shortening of the main engine and a lower consumption of power to produqe the necessary scavenging air. All manouevring gear for the main engine, together with the main switchboard and air control valves are arranged on the top platform, which thus becomes the starting platform, leaving the bottom platform quite clear and greatly improving the access to the crankshaft and other moving parts. Sea water is used for cooling the jackets and covers, and the cooling of the pistons can be either by salt water or fresh water, as desired.
A workshop is arranged on the 'tween decks on the port side, and a harbour lighting set driven by a two cylinder hot bulb engine is situated on the starboard 'tween decks. The other machinery situated at the top platform level includes a vertical boiler for heating the oil in the tanks and for supplying steam to the evaporator, four starting air receivers and a piston water cooler. The auxiliary machinery on the bottom platform includes two centrifugal jacket cooling pumps, two centrifugal piston cooling pumps, centrifugal bilge and sanitary pumps, a ballast pump, spare lubricating pump and piston cooling water transfer pump, two auxiliary air compressors, two oil fuel transfer pumps, and an emergency bilge pump. There is also a centrifugal oil separator for dealing with the lubricating oil and an electric heater for heating the oil before passing it through the separator. On the bridge deck there is a small emergency lighting set and emergency compressor, a small refrigerating plant and fire extinguishing plant are situated in compartments further forward. There are silencers for the main and auxiliary engines in the base of the funnel, which is also used as an upcast ventilator for the engine room.
During trials a speed of 13 knots was reached on the measured mile, and reversal from ahead to astern occupied about 12 seconds. Under dead slow conditions the engines ran steadily with two cylinders only on fuel at about 30 revolutions per minute. There was a total absence of smoke in the exhaust and a marked lack of vibration. The whole of the diesel machinery, including the two 410 b.h.p. auxiliary engines, was built by. Messrs. Alexander Stephen and Sons at their Linthouse works, the castings being supplied by Messrs. A. F. Craig and Company, Paisley.
At the time the two main engines were the largest Sulzer marine diesels built in the United Kingdom to date. The engines were of the two stroke design of which there were few in service, excepting the Dalgoma only one other large British ship had this type of engine. In place of scavenging cylinders the scavenging air (at 2lb per sq in) is supplied by electrically driven turbo blowers. Compared with the four stroke engines these Sulzer engines are said to be remarkably compact.
During January 1926 the Dalgoma made her first trip to Australia, departing Calcutta on January 5th, stopping en-route at Singapore, leaving there on January 11th for Fremantle. The ship arrived at Fremantle on January 19th, sailing the next day for Port Adelaide and arriving there on January 25th. The ship's cargo included 1,000 tons of Indian produce and gnanies (?).
The Argus, Melbourne January 30th 1926 reports: According to the pilot who brought the ship to a berth in Victoria Dock Melbourne British India Line motor ship Dalgoma waa the easiest vessel to handle of those he had brought into a berth. The Dalgoma is one her first visit to Melbourne, with pasengers and cargo from Calcutta. The ship is in charge of Captain E de G Diamond.
The February 9th 1926 issue of The Advertiser, Adelaide reported:
Interfered With Sydney, February 8th.
On February 16th 1926 the Dalgoma departed Sydney for Newcastle, later clearing the Newcastle Customs House destined for Rangoon.
Perth, May 12th 1931: the local newspaper reported:
Perth May 13th 1931 : The slight moderation of the gales permitted the motor vessel Dalgoma which put to sea after being sighted off Rottnest Island at the weekend, to make an anchorage in Gage Roads yesterday. At Perth the ship would load 7,000 tons of wheat.
May 20th 1931 : The recent cyclone which devastated the sugar cane crop in Mauritius, was the worst storm which had visited the island since 1802 according to Mr L.B. Jenkin an officer of the British India fleet, who was visiting Fremantle on the motor vessel Dalgoma. Mr.Jenkin said yesterday that the cyclone lasted three days. Mauritius produced about 250,000 tons of sugar annually, and the whole of the output was absorbed by Great Britain. - The Western Australian (Perth) May 20th 1931
The Dalgoma sailed on June 4th 1931 from Fremantle for Bombay with a cargo of wheat.
The Houston Everest Flight April 1933:
When the Dalgoma arrived in London just before Christmas in 1935 its cargo included twelve monkeys from Bombay. The monkeys escaped before disembarkation and, although most were soon recaptured, two made it into the rigging and one was still there when the ship sailed for Hull. The renegade monkey returned to the deck before the ship reached the Humber. (P&O Heritage Collection)
The Dalgoma survived World War II, being noted in quite a variety of convoys. At the start of hostilities in September 1939 the Dalgoma was active in the Mediterranean working between Port Said, Alexandria, Gibraltar and Liverpool.
During 1940 further convoys were worked to Gibralter, but no longer venturing into the Mediterranean. Much time was spent between British ports, although at least one trip is recorded as reaching Freetown, Sierra Leone during November 1940.
A trip across the North Atlantic took place during June/July 1941, with another sailing to Freetown in September as well as shorter journeys between British ports. Freetown was also visited during early 1942.
1943 & 1944 found the Dalgoma operating across the Indian Ocean, including such ports as Durban, Bandar Abbas, Bombay & Columbo. Ironically about a month after the war ended in Europe the Dalgoma suffered damage in an incident at Fremantle.
The Western Australian, Perth October 5th 1945:
The Samuel Plimsoll is reported to have finally sunk on June 18th 1945 and was eventually raised in sections and dumped on the wreck site of the Lygnern, Beagle Rocks, south of the South Mole.
The Argus MELBOURNE October 9th 1945:
The Dalgoma is recorded as still being present at Fremantle on August 17th 1945, but had reached Melbourne by at least September 10th 1945 and remained here under repair until about December 12th 1945.
On December 13th 1945 the Dalgoma sailed for Bombay.
About February 1947 the Dalgoma was sold for scrap to Belgian ship breakers for about £6,000. The ship would ber scrapped at Ghent.
