In 1932, a steel-pier island( 60 90 feet with a 25-ft air space )was built mile offshore by a little oil company, Indian Petroleum Corp., to support another onshore-type rig. Although the wells were frustrating and the island was damaged in 1940 by a storm, it was the leader of the steel-jacketed platforms these days. Subsequently, a 9,000-ft well was drilled in 1941 in fashion comparable to the California wells by use of a wood pier. With the start of The second world war, nevertheless, all overseas drilling activities stopped.

These barges typically required pilings around them to keep them from being moved off place by winds and waves. The unit, which was a conversion from an inland drilling barge, had two stability pontoons, one on each side of the barge, that hydraulically boosted and down as the barge was immersed and pumped out. These pontoons offered the essential stability for this operation. The Breton Rig 20, later on called the Transworld Rig 40, was a significant step forward because it got rid of the expense
