Early in 1970, the drilling contractor, SEDCO, Inc., was engaged to design, construct and operate the drilling unit, now known as the "SEDCO 445." At the same time, Royal Dutch/Shell and SEDCO engineers undertook detailed final development of advanced forms of dynamic stationing and underwater drilling equipment.

The SEDCO 445 is a self-propelled, dynamically stationed deep sea drill ship, which is designed, configured, and equipped to serve as a highly mobile and efficient floating drill platform capable of conducting offshore drilling operations worldwide.

Dynamic positioning (DP) started out as an exotic control technology for geological core sampling in deep waters in the early 1960s. The technology gradually became more advanced during the 1970s,...

This paper discusses the development and operation of the SEDCO 445's dynamic stationing system during the past three years. In particular, the presentation includes a description of the dynamic stationing components and how they operate; a review of the preliminary design and trial stage; and a discussion of how the system has performed while ...

1970s During this decade, Transocean legacy companies continued to pioneer dynamic positioning (DP) and other marine technology, enabling rigs to move between wells and stay on drilling locations using thrusters. 1971 - The Sedco 445 became the first modern self-propelled drillship. The rig later was called the Deepwater Navigator

a true leader and pioneer in the DP industry. ing rig. This rig was subsequently deployed two miles offshore and drilled Shell’s first offsh dco-445. Following these achievements in the industry, more than 4000 DP systems have been developed worldwide using Mr. Shatto’s initial ideas an

De Sedco 445 was een boorschip dat in 1971 werd gebouwd voor Sedco door Mitsui Engineering & Shipbuilding. Sedco ontwierp het met Shell en Earl & Wright en het was uitgerust met een dynamisch positioneringssysteem (DP). De naam volgde uit de lengte van 445 voet, 135,6 meter.
