Docking & Lock Approach
Docking at an oil terminal or entering a lock is a very critical moment. Both vessel crew and the pilot must have a clear and complete picture of the situation during ship maneuvers, including approach distances, speed and direction, as well as precise rate of turn. In particular, the bow and stern speed are vitally important values where certain vessels are prohibited from approaching the key wall or oil terminal with speeds faster than for example 5 cm/s. For these types of operations Qastor provides “Docking mode” and “Lock approach mode”.
On entering one of these modes, the entire Qastor navigation screen changes automatically, only displaying the information necessary for the mariner to focus completely on the current task without distraction by other events. The Qastor display automatically switches to a head-up or mooringline-up orientation instead of north-up, and shows two speed vectors, one from the bow and the other one from the stern. By activating vessel path prediction, the mariner can see the complete picture of how the vessel is moving now and what the trend of the movement is over the next period of time. Furthermore, the side panel automatically changes to show all relevant information. Besides the basic information already available, it can show, for instance, the lateral speed of the bow and stern, as well as the in-line speed of the vessel. Speed units can be changed from knots to meters per second or centimeters per second.
visual and audible alerts
Visual and audible alerts are provided in Qastor to warn the pilot if his vessel approach speed is faster than permitted. Such alerts are only fired when the vessel is within a certain range of the key wall or terminal.
“Mooring lines” or “lock lines” further assist in safe maneuvering. The user is able to create his own lines on either the key wall or the lock walls within Qastor. Qastor uses these navigation lines to measure the distance from each side of the vessel to the mooring or lock line.
It is important that Qastor provides a stable and reliable image of the situation. Therefore the position, heading and ROT are filtered to eliminate GNSS position jumps. The use of a high-end PPU, enormously improves the accuracy and stability of computed position, heading, speed and ROT.
Qastor can send the docking display information via WIFI to a PDA or a smart phone to the pilot standing out on the bridge wing. This way the pilot has all the necessary information at hand without having to carry a laptop outside.
