The Southern Whaling and Sealing Company Ltd (SWSC) were a United Kingdom-based whaling and sealing company, originally formed in 1911 by the partnership of Richard Irvin & Sons of North Shields and the South African-based fishing company Irvin & Johnson. Latterly they were sold to Lever Bros., in 1919 and re-sold to Christian Salvesen Ltd in 1941.

Early days Richard Irvin & Sons Richard Irvin was born in North Shields in 1853, entering the fishing trade in 1864 at age 11. He quickly saw the potential growth of trawl fishing.

Richard Irvin & Sons had already established the Shields Engineering Co and, after purchasing Youngs Dock Co., merged them to become Shields Engineering & Dry Dock Co. Latterly they then became involved in the herring drifting fishery around the same time as steam powered drifters began to be used in NE England and Scotland. The East Coast Herring Drifter Co. was set up in 1900 followed soon after by the Shields Ice & Cold Storage Co. Ltd.

In 1902, Richard's second eldest son, George Driver Irvin was sent to South Africa to investigate the fishing potential there where George established The African Fishing & Trading Co. in 1903, with offices in Cape Town & North Shields.

Irvin & Johnson However, the African Fishing & Trading Co. was not profitable and only continued to operate after a merger with another South African fishing company owned by Swedish pioneer Carl Ossian Johnson (1867-1949) in 1909. This merger subsequently lead to the establishment of the firm, Irvin & Johnson in Dec 1910.

Foundation In July 1911 Richard Irvin & Sons were granted a licence to engage in whaling from Prince Olav Harbour in South Georgia, and in partnership with Irvin & Johnson, formed a new company, The Southern Whaling & Sealing Company Ltd (SWSC). George Driver Irvin was made Managing Director.

During 1911 they bought Sound of Jura, to be used as a cargo transporter, and also purchased a second hand ship, the Restitution.

The shipbuilding firm of Smith's Dock Co., Middlesbrough were commissioned to construct two steel 92 ft. diesel-powered whale catchers as well as fit a diesel auxiliary in Sound of Jura. However, the diesel engine proved to be unreliable and felt to be too noisy in scaring off the whales, so was replaced by a steam engine.

As well as having a whaling lease at Prince Olav Harbour, South Georgia, SWSC established a station at Port Alexander in Angola. They also undertook some sealing expeditions to Marion & Prince Edward Islands from Cape Town, but these proved unsustainable.

The 1916–17 season failed to produce any whale oil and saw the commencement of the construction of the shore station at Prince Olav Harbour.

SWSC worked in co-operation with Salvesen's at Leith Harbour in 1915–17 to produce as much blubber oil as possible for the war effort in Europe.

Lever Brothers ownership In 1919 SWSC was sold to Lever Brothers. Lever Bros. developed and modernized the Prince Olav Harbour and operated it until it was closed in 1931.

Lever Bros., who later became Unilever, sold the company to Christian Salvesen Ltd in 1941 when they moved out of the whaling business. This increased Salvesen's fleet by two factory ships and 15 catchers.

Fleet Ship Built Speed (knots) Type GRT NotesSV Sound of Jura1896 Transporter1109She was a 4-masted barquentine. She was purchased by the newly formed SWSC in 1911, and fitted with an auxiliary 4-cylinder Polar-Diesel 260 bhp engine later the same year by Smith's Dock Co, Middlesbrough. 1912-13 saw the dismasting of Sound of Jura on her homeward voyage. It was carrying a load of whale oil in its bulk tanks which had made the replacement of the mast impossible until the oil had been pumped out.

There was an explosion in the engine room on 24 September 1912 which resulted in assistant engineer William B Teasdale receiving fatal injuries. The diesel engine was not repaired and eventually removed in 1914. She was refitted with auxiliary steam engine in 1916 by T Abernethy & Co Ltd, Aberdeen. During the 1915–16 season, Sound of Jura is recorded as having left South Georgia en route to Falmouth with 9,100 barrels of whale oil. She didn't return to Britain in 1917, instead choosing to go to Baltimore, presumably because of the submarine threat. The Sound of Jura didn't return to South Georgia for the 1918–19 season. She was sold to Irvin & Johnson in 1922. Her last voyage was to Kerguelen in 1926-27 for the Kerguelen Whaling & Sealing Company. She was eventually scrapped in Cape Town in 1938.SS Restitution1885 Whale Factory3290Built at Wigham Richardsons and Sons, Newcastle upon Tyne, and bought from R Conway & Co., Liverpool.
