John T. Hayward was born in Liverpool, England in 1890. He graduated from Seafield Park Engineering College and obtained a diploma in Marine Engineering from Liverpool University. In 1909, he was apprenticed to a Belfast shipyard. In 1911, he went to Romania to superintend building of a pipeline pumping station and, in 1914, he grew to become drilling and manufacturing superintendent for the Rumania Consolidated Fields Co.’s Bana Moreni area.
During the civil warfare he was trapped in Bessarabia (right now Moldova), however managed to work his approach throughout Russia and escape by way of Murmansk.
He returned to Romania in 1919 as Chief Engineer for Phoenix Oil and Transport Co. who, in 1927, despatched him to the United States to buy manufacturing and refining gear. This go to determined Mr. Hayward to immigrate to this nation and he grew to become a citizen in 1931. From then to 1942, he was Chief Engineer for Barnsdall Oil Co. based mostly in Tulsa, Oklahoma.
Hayward joined the Navy Department in 1941 as Chief Scientist on the underwater warfare take a look at station in Solomons.
He returned to Barnsdall Oil Co. in 1945. In 1947 he was requested to carry the corporate, which held some leases in Breton Sound off the Mississippi coast, into the offshore business. They wanted a expertise development to take action. Hayward in time got here to imagine the corporate ought to construct its personal cellular offshore drilling unit – a revolutionary one. To produce such a rig, Hayward envisioned combining the most effective options of inland barges with these of piled platforms to create a single, moveable, and steady unit, which finally was dubbed the submersible rig.
“Hayward’s design was, in truth, a barge hull related to a separate drilling deck by a collection of supporting columns. Even when submerged, the peak supplied by the posts left the drilling deck excessive and dry. This eradicated the rocking impact brought on by storm-amplified waves, since a lot of their power handed harmlessly by way of the house between the barge and the drilling deck. Workers may empty the buoyancy tanks and re-float the barge hull, making it a very cellular drilling unit.”
The rig, christened Breton Rig 20, went to work on the Breton Sound prospects instantly after building at a coastal shipyard. Its profitable drilling in as much as 20 ft of water put the rig in excessive demand by different operators. However, the rig’s official identify didn’t stick, and it got here to be known as the Hayward-Barnsdall Rig, even after Kerr-McGee purchased it in 1951 and named it Transworld Rig 40. The rig labored steadily till it was retired from the fleet in 1968 and scrapped. The Breton Rig 20 can lay a declare that it was the premier Mobile Offshore Drilling Unit (MODU) although it usually drilled in shallow water which was lower than 20 toes.
