Abstract: The cargo payload of a merchant’s vessel is a crucial variable in calculating revenue for a particular voyage and estimating global trade flows for key commodities. However, due to the opaque nature of the industry, payload information is usually not publicly available. This research utilizes, for the first time, vessel draught information reported by the automatic identification system (AIS) to estimate vessel payloads. The applicability and reliability of draught measurements from AIS captured via satellites and terrestrial receivers are addressed in the process of identifying the most efficacious way to estimate vessel payloads.

AIS Problems Revealed in East China Sea

There are limitations with equipment which precipitate this issue; however, the major concern is with the lack of international laws to prohibit the use of AIS transponders. The IMO needs to take a stand on this issue and prohibit the use of AIS on anything other than a vessel. One solution could be designating AIS symbols for vessels and others for fishing nets, buoys, and other gear such as long lines, hydrographic survey or dredge equipment. This would allow the prudent mariner to differentiate between ships and other floating gear allowing for a reasonable assessment of a close quarters situation.

Vessel density map

In June we left you with a promise: we’d make a vessel density map of EU waters and we’d share it on our portal for you to view and download. In the meantime, several things have happened. A meeting took place in Brussels in September and the discussion ensued enabled us to better define the requirements that the maps should have to be as useful as possible to the maritime community.

M2M Satellite Communication Market: Global Industry Analysis and Forecast 2016 – 2024.


M2M is a technology that allows both wired and wireless systems to communicate with other similar devices. With this technology companies are able to use various M2M communication applications to transfer and control their data in areas without broadband networks. The crucial aspect of M2M (machine to machine) satellite communication is that it can reduce cost and can work in any region. Satellite has a worldwide reach and it is highly scalable.

Let us enlighten you about LED lighting!
Potential interference of VHF-FM Radio and AIS Reception

The U.S. Coast Guard has received reports from crews, ship owners, inspectors and other mariners regarding poor reception on VHF frequencies used for radiotelephone, digital selective calling (DSC) and automatic identification systems (AIS) when in the vicinity of light emitting diode (LED) lighting on-board ships (e.g., navigation lights, searchlights and floodlights, interior and exterior lights, adornment).

Something Fishy

Something fishy in the fisheries department.

Simply put, the Department of Fisheries and Aquaculture is too understaffed and under-equipped to meet the basic requirements of its role. As a result, a substantial percentage of Maltese fishing vessels are operating without any regular supervision at all.

Last week, the Auditor General published a report focusing on how the Department of Fisheries and Aquaculture (DFA) carries out its inspectorate functions.
