The effectiveness of dynamic positioning in offshore operations
Dynamic positioning (DP) is a system that employs a set of mechanisms that enables a vessel to remain afloat on a specific position or a pre-determined path in deep waters. It is a computer-controlled system that helps a vessel or marine structure float without using an anchorage system, allowing offshore operations using active thrusters.
Drilling in shallow waters may allow the use of a jackup positioned on the seafloor holding the vessel still. However, offshore drilling in dip waters, including offshore oil and gas exploration, requires the vessel to stay afloat in a particular position. A semisub or a drillship can help the vessel float above the location during the entire operation.
Thrusters are vital components of the system as they help the structure gain and maintain stability and avoid being displaced by sea turbulences. Since its discovery, the DPS theory has gone through significant developments to achieve the control and accuracy it boasts. Today, the system is employed extensively in shipping and other maritime constructions.
The DP system must be stable enough to withstand the effects of the strong winds, waves and currents experienced in the deep sea. Any excessive movement caused by changes in currents can damage the system halting the operations and causing extensive damages.
