Dynamic Positioning

IMCA Report Covers Mini RadaScan System for DP Ops

Reliable and robust methods of positioning are required for safe vessel operations at offshore installations. The development of dynamic positioning (DP) systems has been gradual over the past 50 years and today, various manufacturers’ systems are available around the world. IMCA has published a report, IMCA M 229 ‘Mini RadaScan microwave radar sensor for dynamic positioning operations’ to provide an overview of the Mini RadaScan system.   “Every measurement technology is bound by limitations (i.e. physics) and external factors (e.g. signal obstruction, solar activity, weather, sea conditions, range), which makes it difficult for one technology to cover all applications and uninterrupted service,” explains IMCA’s Technical Director, Richard Benzie. “Hence the growth in the use of DP has been accompanied by the development of international recognized rules, standards and guidelines against which DP vessels are designed, constructed and operated.   “The growth and development of DP systems has stimulated the development of DP position measurement sensors which have become more sophisticated as technology has allowed. Within the relative position measurement equipment range the DP market is familiar with the use of laser and microwave sensors (the topic of various standalone IMCA publications)


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.

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
