US MANDATES INSTALLATION OF AIS TRANSCEIVERS

On 30 January 2015, the US Coast Guard ("USCG") formally published new regulations (the "Rule") which require more commercial vessels in US waters to install and operate a USCG-certified AIS transceiver within the next thirteen months.

The Rule requires that certain categories of commercial vessels, such as fishing boats, tugs, and ferries operating in US territorial waters install a USCG certified AIS transceiver. Some categories of vessels are required to install a Class A type transceiver and others an AIS Class B type device. Further details of the Rule can be found at: www.uscgportsupply.com

The Rule, which comes into effect on 2 March 2015, provides that vessels must be in compliance by 2 March 2016.

Simon Tucker, CEO of SRT, said:

"We are delighted that the USCG has published this Rule as part of its long term adoption and rollout of AIS based e-navigation and a general global trend of authorities requiring commercial vessels to fit AIS transceivers. We have already started to see orders from customers as recently announced, and expect to see demand for our USCG certified Class A and Class B transceivers increase significantly over the 12 month implementation period from customers addressing the US commercial boat market."
