In the wake of the Deepwater Horizon casualty there have been a number of proposals put before Congress for new legislation or amendments to existing legislation affecting vessel owners and operators. Many of these relate to liability for damages sustained as a result of the casualty or the oil spill that followed. Perhaps the oldest legislation to which amendment and / or appeal is being sought is a statute passed in 1851 to provide vessel owners with limited liability in respect claims brought against them in certain circumstances involving, amongst other things, marine casualties.
