Drug Trafficking on Ships

Also available in these languages

Ships are attractive to drug traffickers. Security is usually lighter than the airline industry and they travel the world. Smuggling by sea has been a problem for years, but in recent years there have been some high-profile cases and evidence that the methods used are constantly evolving.

A conservative estimate values the illicit drug trade at over US$400 billion per year. In Colombia it’s cheaper to produce cocaine than coffee per gram. Match this with a huge global dependency on drugs, then it presents a low-cost, high-risk and potentially high-reward business model.

The main players

The potential for high profits attracts major international criminal organisations and terrorists. Those at the top are not the ones transporting the illicit goods. So, who is?

Couriers and mules

If a vessel is being used to smuggle drugs, it is very plausible that the crew have no idea whatsoever that drugs are on board. In such cases, it is possible that port staff may be involved, such as a stevedore who has access to parts of the vessel and can move around without raising suspicion. Or smugglers can board the vessel (or attach drugs to the hull) from the seaside or at anchorage. There are numerous opportunities.

Targeting crew

Crew are vulnerable, however. Professional traffickers have been known to target crew, either by befriending them during shore leave or taking advantage of any money worries they might have or indeed a drug addiction. Blackmail might also be a factor.

Crew are attractive to traffickers. They have specific access to suitable hiding places on board, for example tanks, enclosed spaces and storerooms. Machinery spaces are ideal for secreting illicit material. Even if the crew member is not the actual courier, they can facilitate the passage of drugs on and off the ship.

In some cases, a courier might not be aware of the presence of a ‘minder’, whose purpose is to ensure nothing prevents the courier from doing their job even if it means interrupting the operation of the ship.

Crewmembers need to look after each other to stop an individual falling into a position where they become vulnerable and therefore a target. Companies should have confidential reporting systems that crew can trust.

Ports and passages – new concerns

Over 90% of goods are transported globally by sea and constantly changing trading patterns between emerging and developing countries create new opportunities to shift illicit goods.

Recent incidents have highlighted a notable increase in the finding of cocaine on vessels trading from Colombia to Mexico. One particular route is Barranquilla to Altamira. Another recent spike in incidents concerns the smuggling of cocaine from Ecuadorian ports. Drugs have also been found at discharge in ports in Turkey and Algeria.

Drugs are sometimes transported via indirect routes. As main routes become better policed, traffickers will select countries with weaker enforcement or corruptible officials.

Location of smuggled drugs

There are too many locations on board of vessels where drugs could be smuggled to list them all. But below we list some of the areas where drugs are commonly found:

Concealment in bulk cargo: packages are hidden within the stow of a bulk cargo, which could be a clean grain cargo or a dirty one such as coal or ore. Drugs have been found close to ladders within the hold.

Containers: Common methods include breaking into the container (and replacing the security seal afterwards) and secreting the drugs with the cargo within. Reefer containers are targeted because the technical space that houses the refrigeration equipment can prove to be a handy hiding place.

Ro-Ro: drugs can be hidden in the cargo of cars, freight vehicles, trailers or coaches

Carry-on: Visitors or crew can quick simply walk on board and leave a package behind

External: Drugs can be attached to ship’s hull. Typically, the rudder trunk and in some cases divers stash drugs on to the underwater area of the hull of a stationary vessel.

On the move: Speedboats are sometimes used to attach drugs to moving vessels.

Preventing drugs getting onto your vessel

Trading in certain parts of the world will put a vessel and its crew at risk of being victims of drug trafficking. There is no magic solution in preventing a determined trafficker. However, there are measures that can be taken to keep safe.

The measures employed by a shipowner and the crew depend on the risk. A voyage from certain South American countries to North America or Europe is clearly higher risk. However, there are plenty other drug routes around the globe and this check should be part of a vessel’s voyage risk assessment.

Assessing the risk

  • Check the level of port security. Secure fences, gates and lighting as well as CCTV and security patrols are just some of the important measures which need to be in place. If a port has poor security measures, the risk to the ship will increase. This requires close co-operation between the ship’s security officer and the port security officer so that an increase in vessel security can be arranged.
  • A strong security presence on the gangway is paramount. A vessel that looks like it takes security seriously is a less attractive proposition to a smuggler.
  • Access points should be restricted and kept to a minimum. A single gangway under close watch is preferable where possible. Pilot ladders should always be raised after use.
  • The ISPS code states that an effective gangway watch is always required with a list of all crew and expected visitors. It’s also very important to check the ID of any personnel embarking your vessel.
  • Restricting access around the vessel and maintaining good lighting on deck are good effective measures. Locking doors that lead into the accommodation, storerooms and technical spaces removes an easy opportunity to hide packages.
  • Locks, code-locks and other devices used to restrict entry should be regularly checked to ensure they are still working.
  • Be aware that stores, spares and repaired or serviced equipment are another easy route for smuggling drugs.
  • If CCTV is fitted on the vessel then make sure it works and covers the right areas.
  • Monitor all around the vessel – including the sea side – for any suspicious behaviour or approaches. If a port has a history of smugglers attaching drugs below the waterline, periodically turn the engine.
  • Searching a vessel for small packages of drugs is a huge undertaking for a small number of crew. But high-risk easily accessible areas can be checked before sailing.
  • Encourage a strong security culture on board your vessel. Crew should be aware of the risks and know the importance of reporting suspicious activity. The more alert and secure crew appear to be then the more they may prevent drug smuggling happening on your vessel.
