The rorqual whale died after colliding with the 185ft Cote d’Ivoirian Star, which was transporting tonnes of bananas from Africa.
The crew sent a call to coastgauds after hearing the impact in the Channel. The ship arrived at the dock with the mammal’s body still trapped on the front of the vessel.
Agencies including the Counter Pollution Team, Receiver of Wreck, Portsmouth International port, Queen’s Harbour Master, the ship`s owner and Environmental and Conservation Agencies were consulted over the death of the whale.
Cote d’Ivoirian is one of four container ships operated by African Express Line (AEL) to visit Portsmouth.
