With any DP vessel operation, comprehensive planning is essential. The operational requirements of the task in hand must be thoroughly discussed with the client, and a detailed plan of the preferred sequence of events compiled. The plan must include the approach to the worksite and set-up, together with the positional requirements of the task itself….

Other vessels have a multi-role function,…
4.1. General Accurate, reliable and continuous position information is essential for dynamic positioning. Some DP operations require better than 3m relative accuracy. A DP control system requires data at a rate of once per second to achieve high accuracy. Reliability is, of course, of vital importance, to operations where life and property may be put…
3.1 – Computers The processors operating the DP control software are generally known as the DP computers. The main distinction of concern to the DPO is the number of computers, their methods of operation, and the level of redundancy they provide. The computers may be installed in single, dual or triple configurations, depending upon the…
2. Basic Principles of DP Dynamic Positioning can be described as an integration of a number of shipboard systems to obtain the ability of accurate manoeuvrability. DP can be defined as: A system which automatically controls a vessel’s position and heading exclusively by means of active thrust. The above definition includes remaining at a fixed…
1. Introduction to Dynamic Positioning 1.1. Dynamic Positioning Systems Dynamic positioning (DP) is a rapidly maturing technology, having been born of necessity as a result of the increasing demands of the rapidly expanding oil and gas exploration industry in the 1960s and early 1970s. Even now, when there exist over 1,000 DP-capable vessels, the majority…
