As Dynamic Positioning is a vessel functions rather than a specific piece of equipment, it can be described as an integration of a variety of components such as Position Reference System (PRS), gyro compasses, computers, propulsion systems and the vessels power plant. DP systems are controlled by means of an Operator Station, usually located on [...]

The watchkeeper is responsible for the monitoring of all equipment related to the control of the position and heading of the vessel whilst in DP mode. DP systems are very complex because via computer control, they integrate a number of different functions relating to the power plant, propulsion systems, and position of heading references.

Navigation in DP Mode
Posted by author on August 30th, 2008
During a DP operations, the watchkeeper must be aware of the proximity of the other vessels or structures which might present a collision hazard. This is especially important in view of the fact that vessels engaged in DP operations are usually unable to maneuver immediately, often being hampered vessels. The appropriate lights and other signals [...]

In making a conventional passage berth to berth, many vessels undertake operations involving navigation in areas where different forms of hazards exist, for example for offshore oilfields. The berth to berth plan should address operational planning within a worksite environment.
When arriving at the operational area or worksite, it is necessary for a detailed operational plan [...]
