Safe towing operation and navigation for towed barge improved by active AIS with solar energy

An Automatic Identification System (AIS) was installed on a barge. The AIS is active using solar panels with charge controller and battery to supply electric power at day time and night time. Such a novel actively AIS can offer the Speed over Ground (SOG), Course over Ground (COG), and position to t...

Description
Summary:An Automatic Identification System (AIS) was installed on a barge. The AIS is active using solar panels with charge controller and battery to supply electric power at day time and night time. Such a novel actively AIS can offer the Speed over Ground (SOG), Course over Ground (COG), and position to tugboat for informing the Master and Officer about the sailing conditions of barge to maintain the towline tension stably and safety of navigation. The AIS also broadcasts the sailing status of barge to other ships in vicinity to maintain situational awareness of collision avoidance. Using this reliable theoretical calculation about the limit tension value of towing line with yawing motion can avoid the limit value of towline tension less than total maximum displacement of tugboat and barge. Those results contribute practical significance for improving the safety of towing operation and navigation at real time.
