Our series of articles on port equipment for LNG terminals is now steering in a more technical direction. Following an analysis of the role of this equipment at a terminal and a review of some of the characteristics of the equipment necessary for a LNG platform, we are now going to begin to take a deeper look at essential port equipment<\/strong>, particularly docking aid systems<\/strong>.<\/p>\n

Docking aid systems<\/h2>\n

One system that aids docking is a maritime information system in real-time that contributes to safe navigation and efficiency<\/strong> during transport. It essentially involves an instrument that provides real-time data to pilots and ground staff<\/strong>, leading to increased safety, reducing risks and improving protection of the environment.<\/p>\n

In technical terms, this involves a system with equipment network architecture and communication interfaces. This equipment is supported by computing hardware, which is in turn controlled by <\/strong>software. This software<\/strong>, which can run on a physical or virtual operating system, is structured across three blocks: Database, control program and display program<\/strong>.<\/p>\n

The system can have one or several checkpoints <\/strong>and may also be accessed using portable Visualisers<\/strong>. The tool’s importance lies in the fact that it provides data<\/strong> in both real-time and stored form, generating operation histories that can be analysed to improve their efficiency<\/strong>.<\/p>\n

We are now going to look at some of the modules available in a docking aid system<\/strong>.<\/p>\n

BAS: Dockmoor-BM (Docking monitoring)<\/h3>\n

Docking and undocking is one of the most important stages <\/strong>of the manoeuvre, making this module a must. Due to the high-volume moving elements of these vessels and their high degree of inertia, it is necessary to control the speeds and the distance to the harbour in<\/strong> order to ensure the safety of the docking operation.<\/p>\n

Laser technology<\/strong> is used to measure the relative distance to the point of contact at the harbour (the defences). Fixed lasers are used for Oil&Gas docking operations to measure the distance to the vessel at two points to be able to extrapolate information related to distance and speed from the bow and stern.<\/p>\n

The basic field equipment are lasers and communication interfaces<\/strong>, and we cannot go any further without mentioning large-scale panels (VMS)<\/strong> to display the information from the command bridge.<\/p>\n

BAS: Dockmoor-MS (Docking tension monitoring)<\/h3>\n

This module allows the tension of the docking lines to be measured.<\/strong> The system is based on a several bolts with inserted load cells that are built into the quick release hooks. Data can be monitored in real time on the screen.<\/p>\n

The load cell is based on a Wheatstone bridge. This transforms the deformation of the bolts in proportional values to the pull tension, which transmits it to the server<\/strong> as analogue data (mV). It is converted to tons on the screen and is represented on the screen<\/strong>. The system can be complemented with pilots in the local communication panel, a display and a siren or beacon near the hook.
