These collisions are common due to more vessels and whales
The Australian Maritime Safety Authority (AMSA) issued a notice providing guidance in reducing the risk of collision with cetaceans (e.g., whales, dolphins, porpoises). Seafarers are reminded that the Australian Whale Sanctuary encompasses all Commonwealth waters from the three nautical mile state waters limit out to the limit of the EEZ.
The purpose of this Marine Notice is to provide guidance to shipowners and operators in reducing the risk of collision with cetaceans (whales, dolphins and porpoises), in accordance with IMO Circular MEPC.1/Circ.674.
Collision with cetaceans (ship strikes) is an issue of growing concern and has become more common due to the increase in both vessel traffic and whale populations. Ship strikes can cause damage to property and increase the risk of death and injury to people and animals. Damage to vessels, ranging from minor to extreme, includes cracked hulls, damaged propellers, propeller shafts and rudders, damaged port and starboard aft strut actuators, broken steering arms and ruptured seawater piping.
