The threat picture
Search interest in maritime security terms rose sharply through mid-2026, driven by attacks on shipping and by the growth of naval coalitions responding to them. Queries such as "bab al-mandab strait maritime risks" and "multinational maritime security coalition" moved by thousands of percent month on month, and "united kingdom maritime trade operations" — UKMTO, the reporting body merchant ships actually call — rose 120%.
Behind those searches is a real operational problem for anyone running ships.
| Threat | Character |
|---|---|
| Armed attack on shipping | Missiles, drones and small-boat attacks in contested waters |
| Piracy and armed robbery | Boarding for theft, cargo or hostage-taking; regional patterns |
| Kidnap for ransom | Crew taken ashore; historically concentrated in specific regions |
| Stowaways | Costly, complex, with humanitarian and legal obligations |
| Smuggling and parasitic attachment | Narcotics attached to hulls or concealed in cargo |
| Terrorism | Against ships, ports and offshore infrastructure |
| Cyber attack | Against navigation, cargo and business systems |
| Sabotage of subsea infrastructure | Cables and pipelines |
| Sanctions-evasion vessels | Uninsured, poorly maintained tonnage creating collision and pollution risk |
The regulatory framework
The ISPS Code, given effect through SOLAS Chapter XI-2, is the backbone. It requires:
| Element | Content |
|---|---|
| Ship Security Assessment | Identify vulnerabilities for the specific vessel |
| Ship Security Plan (SSP) | Approved, confidential, ship-specific |
| Ship Security Officer (SSO) | Named, trained officer on board |
| Company Security Officer (CSO) | Named ashore |
| Security levels 1, 2, 3 | Escalating measures, set by the administration or port |
| Ship Security Alert System (SSAS) | Covert alert to shore |
| Declaration of Security | Ship-port or ship-ship agreement where levels differ |
| Drills and exercises | At defined intervals |
Alongside it sit industry guidance — BMP Maritime Security and its regional supplements — and the naval reporting and coordination structures: UKMTO, MSCHOA and the various multinational coalitions operating in high-risk areas.
What ships actually do
Reporting and registration. Registering a transit with UKMTO or the relevant coordination centre, and reporting position as required, costs nothing and puts naval assets in a position to help. It is consistently the highest-value single measure.
Enhanced watchkeeping. More lookouts, radar vigilance, night-vision equipment where appropriate, and a bridge team briefed on what to look for.
Hardening. Razor wire, locked access points, protected bridge windows where the threat justifies it, and controlled access to accommodation.
Citadel. A secure, provisioned space with independent communications where the crew can shelter. Effective only if it is genuinely secure, genuinely provisioned and drilled.
Water and foam. Deterrent against boarding by small craft.
Private armed security. Legal in some jurisdictions and not others, requiring flag state approval, careful contracting, and a clear rules-for-the-use-of-force framework. Expensive, and to be used where the threat assessment genuinely warrants it.
Routing. The most consequential decision, and a commercial one — transit versus a longer alternative, weighed against war risk premium, fuel, time and crew consent.
Crew: the part that gets overlooked
Security decisions land on people who did not choose the route. Obligations and good practice:
- Informed consent. Seafarers should know when a vessel will transit a high-risk area, and where collective agreements provide rights of refusal or additional compensation, those must be honoured.
- Training and drills specific to the threat, not generic.
- Psychological support during and after transits, and after any incident.
- Family communication protocols — crews' families follow the news.
- Post-incident care, including access to support and, where necessary, repatriation for treatment.
Under the MLC 2025 amendments, key-worker recognition and non-discriminatory repatriation obligations reinforce the shipowner's duties. Entry into force is expected in late December 2027.
Building a security posture
- Threat assessment per voyage, not per year, using current information from naval coordination centres and industry sources
- SSP that reflects the actual threat, updated when the picture changes
- Pre-transit briefing for the whole crew, recorded
- Reporting and registration with the relevant coordination body, every transit
- Drills covering boarding, citadel entry and communications loss
- Insurance notified and war risk cover confirmed before entry
- Post-transit debrief captured and shared across the fleet

Frequently asked questions
What is the ISPS Code?
The International Ship and Port Facility Security Code, given effect through SOLAS Chapter XI-2. It requires security assessments, approved ship security plans, designated security officers, alert systems and defined security levels.
What is UKMTO?
United Kingdom Maritime Trade Operations — a body through which merchant vessels report movements and incidents in certain regions, acting as a link between merchant shipping and naval forces.
Are armed guards allowed on merchant ships?
It depends on the flag state, the coastal states involved and the ports of call. Where permitted, use requires flag approval, careful contracting and a clear use-of-force framework.
Can a seafarer refuse to sail into a high-risk area?
Rights vary by collective agreement, employment contract and national law. Many agreements provide for notification, additional compensation and, in some cases, the right to decline. Owners should address this explicitly rather than assume.
