Steamship
In 1783, the Pyroscaphe became the first working steamboat to navigate a river. Denis Papin conceived the idea of steam propulsion in the first half of the eighteenth century. Alonso Péan and Louis de La Saussaye documented these early experiments. The technology moved from small riverboats to larger ocean-going vessels over the next few decades. Richard Wright's Experiment steamed from Leeds to Yarmouth in July 1813 as the first sea-going steamboat. Aaron Manby crossed the English Channel in 1822 as the first iron steamship to go to sea. She arrived in Paris on the 22nd of June 1822, carrying passengers and freight at an average speed of five miles per hour. The Savannah left Savannah, Georgia, on the 22nd of May 1819, arriving in Liverpool, England, on the 20th of June 1819. Her engine ran for only part of the eighteen-day journey. Isambard Kingdom Brunel built the Great Western in 1838 as the first purpose-built trans-Atlantic paddle steamer. This vessel initiated the era of scheduled trans-Atlantic ocean liner service.
Paddlewheels performed best when operating at a specific depth but suffered performance drops when ships became heavier. Francis Pettit Smith designed the Archimedes in 1836 with a screw propeller that remained submerged regardless of ship weight. James Watt applied the first screw propeller to an engine at his Birmingham works. An effective stern tube required water-lubricated bearings to prevent leaks along the shaft. A lignum vitae bearing patented in 1858 solved early wear problems. Alfred Holt launched the Agamemnon in 1865 with a compact compound engine running at high boiler pressures. Triple expansion engines expanded steam successively through three cylinders to improve efficiency. The Aberdeen achieved a fuel consumption reduction of about sixty percent compared to typical steamers from ten years earlier. By 1885, virtually all ocean-going steamships were ordered with triple expansion engines. Steam turbines replaced reciprocating engines after Charles Parsons demonstrated his Turbinia yacht in 1897. The Cunard RMS Mauretania adopted the steam turbine in 1906 and set new standards for speed and power.
The Great Western Steamship Company formed in 1836 to build vessels for the Bristol-New York route. Brunel's Great Western was the largest steamship for one year until the British Queen entered service. She carried passengers and cargo across the Atlantic using four masts for auxiliary sails. The SS Great Britain became the first iron-hulled screw-driven ship to cross the Atlantic in 1845. Iron hulls offered greater structural strength than wood and avoided dry rot or woodworm issues. The SS Great Eastern followed as Brunel's last major project between 1854 and 1857. This liner featured a double hull with watertight compartments and four funnels. Her gross tonnage reached almost twenty thousand tons with capacity for thousands of passengers. White Star Line's Oceanic set a new standard for ocean travel in 1870 with electricity and running water. The RMS Mauretania launched in 1906 became one of the first liners to use steam turbines. The Titanic sank in 1912 while being the largest steamship in the world at that time. The SS Normandie, launched in 1938, held the title of largest passenger steamship ever built.
Steamships enabled new trade routes by reducing dependence on wind patterns. No steamship could carry enough coal to reach the Far East before 1866 without sacrificing commercial cargo space. The Peninsular and Oriental Steam Navigation Company used an overland section between Alexandria and Suez to bridge this gap. The opening of the Suez Canal in 1869 saved about seven thousand miles on the route from China to London. Steamships immediately utilized this waterway and found high demand during the 1870 tea season. Forty-five ships were built in Clyde shipyards alone in 1871 for Far Eastern trade. Alfred Holt's Blue Funnel Line operated ships that could sail from London to China with coaling stops at Mauritius. Triple expansion engines allowed vessels to operate as primary maritime transport in most commercial situations. By 1890, steamers constituted fifty-seven percent of world tonnage. This share rose to ninety-three percent by World War I. International trade increased to unprecedented levels due to these technological advances.
Marine diesel engines matured as an economical alternative to steam power after World War II. Diesel engines offered better thermal efficiency and required less supervision and maintenance than reciprocating steam engines. No commercial ocean-going steamers with reciprocating engines have been built since the 1960s. The last passenger steamship to cross the Atlantic on a scheduled liner voyage was Queen Elizabeth 2 before conversion to diesels in 1986. Steam turbine-driven merchant ships like Algol-class cargo ships were built until the 1970s. LNG carriers now represent the primary niche market for steam turbines. About ten percent of newbuildings in 2013 utilized steam turbines for liquefied natural gas transport. The Seri Camellia-class LNG carriers built by Hyundai Heavy Industries started production in 2016. Hybrid power plants combine steam turbines with gas engines for improved efficiency. Most steamships today remain powered by steam turbines or nuclear reactors.
