The advent of the marine diesel engine revolutionized maritime transport, offering a more efficient and reliable alternative to steam power. This article delves into the early development and deployment of diesel engines in marine vessels, highlighting key milestones and the transformative impact on the shipping industry. From the pioneering French canal barge "Petit Pierre" to the groundbreaking Danish cargo ship "Selandia," we explore the origins of diesel propulsion at sea, its rapid evolution, and the enduring legacy of these technological marvels.
The journey of marine diesel engines began in 1903 when the French canal barge "Petit Pierre" made waves on the Marne-Rhine canal. This vessel was equipped with a fast-running diesel engine that produced 25 horsepower at 360 revolutions per minute (rpm). This marked the first recorded use of a diesel engine for marine propulsion.
The following year, in 1904, the French Navy introduced two marine diesel engines in the submarine 'Z,' each delivering 120 horsepower. This was soon followed by the launch of another French diesel submarine, the 'Aigrette,' in 1905. The 'Aigrette' featured a more conventional four-stroke engine that generated 200 horsepower.
The first commercial sea-going application of diesel engines occurred in 1908 when the Swedish engine manufacturer A.B. Motorer supplied 120 horsepower, 300 rpm reversible engines for the 350 deadweight tonnage (dwt) cargo ships "Rapp" and "Schnapp." These vessels operated as coasters, navigating the Baltic and North Sea.
In the same year, Russia made its mark with the construction of the Caspian Sea tanker "Djelo," a 4,000 dwt vessel powered by two 500 horsepower, 150 rpm engines. By 1909, Russia had built two larger tankers, each equipped with even more powerful diesel engines.
The transition to diesel power also included sailing ships fitted with auxiliary engines. In 1910, the famed explorer Roald Amundsen's ship "Fram" was outfitted with an A.B. Diesel Motorer engine. That same year, Italy launched the 1,000-ton cargo vessel "Romagna," powered by a two-stroke Sulzer engine capable of 380 horsepower at 250 rpm.
An interesting development in 1910 was the construction of a lightweight V-8 diesel engine for Emanuel Nobel's yacht "Intermezzo." This engine produced 200 horsepower at 600 rpm while weighing a mere 10 kilograms per horsepower.
The "Vulcanus," a small tanker with a displacement of 2,047 tons and a deadweight of 1,216 dwt, set sail in 1910. It featured a six-cylinder reversible engine that produced 450 horsepower at 180 rpm. The "Vulcanus" primarily operated in the Far East, traveling between Borneo and Singapore. When compared to a similar steam-driven tanker, the diesel-powered "Vulcanus" consumed only 2 tons of oil versus 11 tons of coal for the steamship, and the crew size was nearly halved from 30 to 16.
On November 4, 1911, the "Selandia" was launched in Denmark. This 7,400 dwt cargo ship, with a displacement of 10,000 tons, was equipped with twin propellers and powered by a Burmeister & Wain eight-cylinder, four-stroke engine that delivered 1,050 horsepower at 140 rpm. The "Selandia" embarked on her maiden voyage in early February 1912 and remained in service until 1942. While not the first marine diesel engine ship, the "Selandia" was the largest ocean-going vessel of its time, showcasing the potential of diesel power in the commercial shipping industry.
The historical accounts of these pioneering vessels are documented in D. Stapersma's "Vulcanus versus Selandia" (July 1996, Voorburg, The Netherlands) and C. Lyle Cummins' "Diesel's Engine" (Carnot Press, Oregon, 1993). These works provide a detailed look into the early history of marine diesel engines and their profound impact on maritime transport.
