Establishment of virtual AIS aid to navigation in Torres Strait

AMSA issues Marine Notice AMSA has identified a number of instances where deep draught vessels may have transited very close to the charted position of OG Rock in the Prince of Wales Channel.For deep draught vessels the practice of transiting close to, or over, the charted position of OG Rock may increase risk, lead to a breach of AMSA's stipulated under keel clearance limit or, in the worst case scenario, lead to a vessel grounding.To assist deep draught vessels navigate in and around this area, AMSA has established a virtual' AIS Aid to Navigation (AtoN). A virtual AIS AtoN is an AtoN that can be displayed on vessel's navigation displays for a location where no actual physical aid to navigation exists.The virtual AIS AtoN readily and clearly indicates the charted position of OG Rock on navigational displays to assist Mariners keep deep draught vessels well clear of OG Rock and to avoid accidental breaches of Under Keel Clearance limits as stipulated in Marine Order 54.The virtual AIS AtoN appears in position (WGS84) 10 degrees 29.865 South; 142 degrees 20.753 East. This should display on vessels' ECDIS / Minimum Keyboard Displays / AIS equipment as a virtual Special Mark. The AIS ...

Reducing the risk of collisions at sea

AMSA issues Marine Notice The Australian Maritime Safety Authority (AMSA) issued a Marine Notice to remind masters, skippers, watchkeepers and all other personnel involved in the operation of vessels about the importance of adhering to the International Regulations for Preventing Collisions at Sea 1972 (known as the Collision Regulations or COLREGs). This Notice also provides guidance for fishing vessels, yachts, barges and towing vessels to reduce the risk of collisions at sea.Application of COLREGsThe COLREGs apply to all vessels including barges, tugs, yachts, both commercial and recreational fishing vessels and all types of cargo and passenger vessels whether underway or at anchor. These regulations are applicable in all navigable waters, from inland waters to the high seas. The Navigation Act 2012 and Marine Order 30 (Prevention of Collisions) implements the COLREGs for Australian vessels and for other vessels operating in Australian waters. Contravention of COLREGs may jeopardise the safety of life at sea and constitutes an offence, for which substantial penalties may apply1.The COLREGs recognise the limitations associated with the navigation of different types of vessels in different waterways. For example, larger vessels may not be able to reduce speed quickly and will often require more sea-room to slow down ...
