Who Owns a Wreck? Rewarding Whoever Saves It

Salvage law grants a reward to anyone who voluntarily saves a ship or cargo from danger at sea, payable by the owner of the property saved, and it operates without any contract having been made. That is unusual, since the law generally does not oblige somebody to pay for a service they never requested, and the doctrine exists as a deliberate exception. The reasoning is that a ship in distress represents property that will otherwise be lost entirely, that assistance is dangerous and costly to provide, and that anybody in a position to help must have an incentive to do so rather than to sail on. The reward is therefore set generously, and the whole arrangement is designed to make rescue worth attempting.

A salvage award depends on several conditions being satisfied:

• •The property must have been in real danger, judged reasonably at the time
• •The service must have been voluntary, so a crew member or somebody under a pre-existing duty cannot claim
• •The effort must have succeeded at least partly, since the traditional rule pays nothing for a failed attempt
• •The salvor must not have caused the danger
• •The award is assessed by a court or tribunal considering danger, value, skill, risk and time
• •It can never exceed the value of what was saved

Requiring success made sense for cargo and became actively harmful once tankers existed. A salvor attending a stricken vessel carrying oil faced enormous expense and the risk of earning nothing if the ship sank anyway, while the greatest public interest lay in preventing the cargo reaching the sea whether or not the ship was saved. The response was a special compensation provision, introduced by international convention in 1989 after several major spills, which pays a salvor for efforts that prevent or minimise environmental damage even where the property itself is lost. A commercial framework introduced later allows salvors to be paid on an agreed basis for such operations. The change is a clear example of law adapting once the harm being avoided ceased to be primarily the owner's loss.

Saving property and saving life are governed by different rules and the contrast is instructive. There is a legal duty on a ship's master to assist anybody in distress at sea, imposed by international convention and by national law, which is unusual because the general law imposes no duty to rescue a stranger on land in most jurisdictions. That duty carries no reward, since saving life earns nothing under salvage law, which is a deliberate arrangement intended to prevent bargaining over a rescue. A salvor who saves both life and property may receive an enhanced award reflecting the lives saved, which is the mechanism reconciling the two principles. Failure to assist is a criminal offence in several jurisdictions, and enforcement in practice is difficult and has become politically contested in some waters.

Historic wrecks raise a different set of questions and the law is genuinely messy. Salvage assumes an owner who benefits, which is awkward for a ship that sank three centuries ago, and various rules apply instead, including the law of finds where property is genuinely abandoned, sovereign immunity for warships which remain the property of their flag state indefinitely, and national heritage legislation protecting designated sites. A UNESCO convention adopted in 2001 promotes preservation in place and discourages commercial exploitation, and it has not been ratified by several major maritime states. Disputes between commercial recovery operations, governments and archaeologists over specific wrecks have produced lengthy litigation, and the underlying tension between treating a wreck as property and as a site is unresolved.

Voluntarily saving property at sea earns a court-assessed reward from its owner without any contract, which is a deliberate exception designed to make rescue worth attempting. The traditional rule paid nothing for a failed attempt, which became harmful with oil cargoes and was modified in 1989 to pay for preventing environmental damage. Historic wrecks fall under a messier mixture of rules.
