Secoba

 

 

The Submarine Products has exported double hose regulators to Denmark as "SECOBA" - Jan Uhre Special.

Henrik Haubroe (April 16, 1915 - July 15, 2014) was a Danish freight forwarder, manufacturer of safety equipment and adventurer and author. He founded in 1946, the company ArSiMa - Occupational Safety Equipment - in Copenhagen. The ArSiMa company has traded apparatus and devices for the protection against industrial accidents, including fastening devices in the form of belts, braces, lines etc., apparatus and devices for the protection of the respiratory system.

In 1966, the company ArSiMa registered the name Secoba. They imported the double hose regulator Atlantic from Submarine Products and used a custom label in their regulators. This regulator honored the Danish diver pioneer Jan Uhre.

 

 

 

 

Jan Uhre was born on December 23, 1916, and died on April 1, 2003. He was an engineer and loved for the underwater adventures. He has became professional diver.

 

 

During 1070-1090 AD, five Viking ships were sunk at Skuldelev, Denmark, to make a barrage across a narrow channel, giving access to the town of Roskilde, thereby protecting the town from enemy raiders. Already in 1898, parts were found by a skipper who gave them to the National Museum. In 1924, some parts were salvaged, when the passage through the barrage was widened.

In 1953, professional helmet diver Jan Uhre located parts of a ship in the murky water and in 1956, sports divers Åge Skjelborg and Hartvig Conradsen found an old ship frame in bad visibility on about 2 m depth. The National Museum started examining the site in 1957. It soon became clear that the ships were from Viking Age, and not Queen Margaret's ship (c 1400 AD) like a local legend says. However, the barrage may have been used until medieval times. Plenty of stones had to be removed before reaching the underlying ships.

In March 15 1953, Jan Uhre, professional frogman and engineer, dived at the obstruction and salvages pieces of the wreck. Participaters: Einar Olufsen, editor, Hans Nicolaisen, fisherman and a professional photographer from a monthly magazine. 

 

1953 - Jan Uhre with parts of the wreck



Jan Uhre maked the very first sketch and took the first known underwater photo of the obstruction and of parts of the wreck, by local people called The Ship Of Queen Margrethe. A report of the excavation with photos was published April 24 in Dansk Familieblad.

Jan Uhre's excavation has revealed that the wreck is clinker-build, and measuring appr. 10 meter by 3 meters. The frames were attachted to the plankings with treenails, but also square-headed ironnails were used, helding the planks together.

 

 

The sketch thatt Jan Uhre made in March 1953 was based on his own examinations of the wreck

 

 

In 1962 the work area was drained and excavations begun. The investigations continued until 1969. It was first believed that there were six ships, but they were five. All of the ships are dated to 11th century AD, and clinker built with iron rivets.

The Skuldelev finds are very important because almost nothing was previously known about Viking merchant vessels in which long distance trade was conducted.
The ships are now displayed at the Viking Ship Museum in Roskilde, near Copenhagen.
