Law of salvage

Law of salvage is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Law of salvage rather than just read about it. In short: The law of salvage is a principle of maritime law whereby any person who helps recover another person's ship or cargo in peril at sea is entitled to a reward commensurate with the value of the property saved. Maritime law is inherently international, and although salvage laws vary from one country to another, generally there are established conditions to be met to allow a claim of salvage.

Key takeaways

  • Law of salvage belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Law of salvage to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Law of salvage from memory before moving on to harder problems.

Reference excerpt

The law of salvage is a principle of maritime law whereby any person who helps recover another person's ship or cargo in peril at sea is entitled to a reward commensurate with the value of the property saved. Maritime law is inherently international, and although salvage laws vary from one country to another, generally there are established conditions to be met to allow a claim of salvage. The vessel must be in peril, either immediate or forthcoming; the "salvor" must be acting voluntarily and under no pre-existing contract; and some life or property must be successfully saved. A modern addition rewards a salvor for the prevention of oil spills and environmental damage.

The basis of marine salvage law With its origins in antiquity, the basis of salvage is that a person helping another at sea is putting himself and his vessel at risk and should be appropriately rewarded. A related consideration was to prevent piracy, since any vessel in peril might well be abandoned to pirates if the owner did not reward an honest salvor. Salvage law has been recognized for centuries in such documents as the edicts of Rhodes and the Roman Digest of Justinian. It is still a nearly universally recognized right, though conditions for awards of salvage vary from country to country. The right to be rewarded for salvage at sea is based both on principles of fairness and public policy: the law seeks to be fair both to the property owners and to the salvors. The legal entitlement to a salvage reward arises when a person, acting as a volunteer (that is, without any pre-existing contractual or other legal duty so to act), preserves or contributes so to preserving at sea any vessel, cargo, freight, or other recognized subject of salvage from danger. A salvage situation arises when a shipowner accepts an offer of help from a salvor. To that extent, the arrangement is contractual, but it is not a contract for services with a pre-arranged fee (such as, say, a towage contract). Instead, the law provides that after the service is done a court or arbitrator will make an award taking into account:

the degree of success of the salvage venture the degree of danger of the salvage venture the value of the property salved whether a reasonable attempt to protect the coastal environment was made the provisions of Articles 13 & 14 of the Salvage Convention 1989. A formal contract is not strictly necessary, provided there is evidence that the owner has acquiesced in the salvor's intervention. The assumption here is that when faced with the loss of his vessel and cargo, a reasonable prudent owner would have accepted salvage terms offered, even if time did not permit such negotiations. Even so, the shipowner is entitled to reject any offer of help, and would do so if the shipping line had already made arrangements with a professional salvor of their choice. There is no equivalent to salvage when ashore: a person who assists another on land has no entitlement unless a court deems that an implied contract had arisen, whether objectively or subjectively.

Recognized subject matter Traditionally, salvage only recognizes a ship or craft ("vessel"), cargo on board, freight payable, and bunkers carried on board as the subject of property in danger. The scope of salvage has been expanded by the 1989 Salvage Convention, and protection of the environment is part of salvage. Oil pollution can cause damage to the environment. If the salvor prevents oil pollution from happening, he indeed performs a valuable service to the community as mentioned by (1997) 1 Lloyd's Rep 323 (HL), pp. 326–328. Therefore, the salvor will be rewarded with special compensation, i.e., liability salvage instead of property salvage. The convention does not consider saving lives to be part of salvage, but if one vessel saves life and the other saves property, the arbitrator may apportion the salvage reward between them as he thinks fit.

Real peril Danger needs to be real but not necessarily immediate or absolute. The subject of salvage must be in real danger, which means the property is exposed to damage or destruction. The burden of proof lies on the salvor, which means the salvor needs to prove real danger existed when the performance of service commenced. The court or arbitrators must determine whether the property was truly in danger. As every situation differs, both subjective and objective tests will be conducted. Common considerations are:

It is incumbent upon the court to assess the existence and level of danger, both present and future. The case of the Troilus (1951 1 Lloyd's Rep. 467, HL) illustrated the concept of future danger that the court must take into account when determining the existence of danger. In this particular case, the cargo owners contended that the ship was in perfect safety when she reached Aden, and therefore it constituted ocean towage but not salvage when towing from Aden to UK. The court held that even though the ship and cargo was in physical safety, the services rendered still amounted to salvage service on the grounds that the master of a damaged ship must do his best to preserve the ship and cargo and bring them to their destination as cheaply and efficiently as possible. The salvage award was reasonable as long as the master acts reasonably for the combined benefit of ship and cargo. In the modern world, the dispute normally is not about whether there is just the existence of danger, but also the degree of danger, as it determines the extent of the award.

Worked examples

Example 1 — a first encounter with Law of salvage

Start with the simplest possible case. Write down what Law of salvage claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Law of salvage before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Law of salvage ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Law of salvage

In research
Law of salvage appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Law of salvage in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Law of salvage is common in secondary-school and first-year university syllabi. It links to neighbouring topics Marine salvage, Maritime law, Maritime transport, so understanding it makes those chapters shorter.
In everyday life
Look for Law of salvage outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
