Abstract: Docking of vessel as a part of sea voyage requires high precision of positioning, reliability of solution, independent architecture and a operator’s knowledge. Article presents integrated system consisting of Laser Measurement System and high precision DGPS System developed for accurate docking of vessel.
Whole system has an augmented architecture that will increase reliability and availability
1. IDEA OF DOCKING SUPPORT SYSTEMS
The concept of the construction of a docking system is to facilitate berthing of a large vessel by an accurate determination of ship hull position in relation to the berth.
Comparing to satellite positioning systems its main advantage is the identification of ship’s distance to the quay independently, as well as the measurement of hull transverse speed relative to the quay. Article presents: PNDS - pilot navigation docking system as main system and its sub systems: PNSS - pilot navigation support system, LDS - laser docking system
For comparison standards of accuracy, continuity and a availability must be presented, main source of its is IMO (International Maritime Organization) in the A.915 document sets out the accuracy level for each type of navigation and for automated docking its at level of 0.1m. This value can be ensured by satellite positioning receivers working with an external system source, such as the RTK (Real Time Kinematic) system. Accuracy at this
level is granted by a laser distance meter operating on the quay, independently from external factors affecting the position received via a satellite system.
Concept of building PNDS is providing solution for pilot following data (Gucma et al, 2010):
• providing accurate position in relation to shore (accuracies of 0.1 m must be acquired in time to readout of 1s )
• multiple laser modules for different type of vessels (ferries, LNG etc.)
• portable display that can be taken into vessel with additional DGPS/SINS module for port passage and berthing (...)
