RADius
A New Short-Distance Position System
based on
Radar Principles

RADius product idea and objective
Security issues
– 1997 - 2001, 24 Reported Incidents of contact or collision between
supply vessels and offshore installations in North-Sea.
Customer demand
– Statoil demands DP class 2 requirements for Supply loading
operations
Legislation issues (IMO)
– .2 For equipment classes 2 and 3, at least three position reference
systems should be installed and simultaneously available to the DP-
control system during operation.
– .3 When two or more position reference systems are required, they
should not all be of the same type, but based on different principles
and suitable for the operating conditions.

DGPS
100m 200m 300 m Distance
Robust and precise relative reference for DP operations when close to
structures or other vessels
Complementary to DGPS e.g. as DGPS tends to have reduced accuracy
close to structure or other vessels, RADius increases accuracy
Increasing integrity by tracking multiple transponders and built-in accuracy
assessment and performance evaluation
