Brief History of Dynamic Positioning

Dynamic Positioning Background. Dynamic Positioning emerged in the early 1960s. With offshore drilling venturing further into increasingly deeper water the use Jack-up Rigs became impractical and the use of anchor spreads often problematic and commercially inviable.

The first Moho well was drilled off La Jolla, (948 meters) California in 1961 by the drill-ship Cuss 1 which had been retro fitted with four steerable propellers.

This was followed by 5 wells drilled of Mexico in water depths of up to 3500 meters. The vessel was kept in position manually using a radar and sonar ranging.

Later in 1961 the Eureka was launched which utilized taut wire position referencing interfaced with an analogue control system.
