Dynamic Positioning

Feature: Dynamic Positioning An Amenity Becomes Compulsory

The inclusion of dynamic positioning systems has become a standard and necessary system on supply boats and many crew/supply vessels. In their simplest form, dynamic positioning systems allow an offshore vessel to "moor" adjacent to a rig or platform without the traditional mooring lines being attached to structure or the use of anchors. Instead thrusters both in the bow and the stern keep the vessel on station. For a more precise definition of dynamic positioning, American Bureau of Shipping (ABS) says, "The dynamic positioning system is a hydrodynamic system which controls or maintains the position and heading of a vessel by centralized manual control or by automatic response to the variations of the environmental conditions (wind speed, current, wave height) within the specified limits." The Oil Companies and DP The development of dynamic positioning systems and the use of them on every new supply vessel being built has a lot to do with the oil companies who own the structures being serviced by the vessels. These companies, with billion of dollars invested in their drilling and production equipment in the Gulf of Mexico (GOM) and elsewhere have insisted that the offshore vessel operators not tie up to their rigs and be able to transfer materials to the platform in advance sea states. The only practical was to way to affect this transfer is to use dynamic positioning systems.

DNV GL says it has introduced a new recommended practice for the training of dynamic positioning (DP) operators. The new standard is based on the latest training and certification principles and defines the role that simulators can play in giving candidates better and more efficient training. Given the differing duration and frequency of DP operations, the recommended practice (RP) does not define a universal sea-time requirement expressed in days
