Maritime charts and insurance notices contain boundaries that can change reporting, cover, security measures or voyage cost. Those lines matter, but they do not all mean the same thing and none of them describes every threat around a route.
The former Indian Ocean piracy High Risk Area, the current Voluntary Reporting Area and the Joint War Committee’s Listed Areas are often discussed as though they were interchangeable. They were created by different bodies for different purposes. Confusing them can leave a team applying the wrong meaning to the right coordinates.
The practical question is not simply whether a vessel crosses a line. It is what that line changes, which threat it was designed to address and what may have changed around the route since the boundary was drawn.
The Indian Ocean piracy High Risk Area is no longer current
The shipping industry established an Indian Ocean High Risk Area during the Somali piracy crisis. Its coordinates helped companies identify where enhanced counter-piracy measures associated with the regional Best Management Practices should be considered.
As attacks fell and the threat picture changed, the industry reduced the area several times. The designation was removed from 1 January 2023. Articles and passage plans that still describe the Indian Ocean piracy HRA as a current boundary are therefore out of date.
Its removal did not declare the western Indian Ocean free from piracy or other maritime threats. It meant the industry no longer considered that particular fixed designation the right way to frame the risk. Current capability, incidents and guidance still need to be assessed for the intended route and transit period.
The Voluntary Reporting Area supports awareness and response
A Voluntary Reporting Area, or VRA, defines waters in which merchant vessels are encouraged to register and share information with the relevant reporting centre. Reporting helps build the recognised maritime picture and supports warnings, liaison and response.
The UK Maritime Trade Operations VRA covers a wide area across the Red Sea, Gulf of Aden, Arabian Sea and western Indian Ocean. Its boundary is a reporting framework, not a declaration that every point inside carries the same risk or that waters outside are safe.
BMP Maritime Security, published in 2025, replaced the former separate BMP5, BMP West Africa and Global BMP publications. It uses a threat- and voyage-specific approach, supported by current reporting arrangements and the Maritime Industry Security Threat Overview. Companies and Masters should use the current publication alongside flag, company and official guidance rather than relying on an older reference to BMP5.

Joint War Committee Listed Areas serve an insurance purpose
The Joint War Committee brings together underwriting representatives from the Lloyd’s Market Association and International Underwriting Association. Its Listed Areas identify places where underwriters may require notification and can consider additional terms or premium for hull war, piracy, terrorism and related perils.
A JWC listing is not a government prohibition, a naval reporting boundary or a complete threat assessment. The effect on a particular voyage depends on the policy wording, the current listed-area notice and the terms agreed with the insurer. The boundaries can also change, so an old chart annotation or copied list should not be assumed to remain current.
The latest circulars and listed-area material should be checked through the Lloyd’s Market Association Joint War Committee and discussed with the relevant broker or underwriter.
One route can cross several different frameworks
A vessel moving between the Gulf and the Mediterranean may enter a VRA, cross or approach a JWC Listed Area and pass through waters affected by missile, drone, piracy or electronic-interference threats. Each fact answers a different question.
The VRA indicates where reporting supports the regional maritime picture. A JWC boundary may change the insurance conversation. BMP Maritime Security provides a framework for assessing threats and considering proportionate measures. The route assessment brings those elements together with the vessel, cargo, timing and current incidents.
For an operator, that may affect planning, reporting and security preparation. An insurer may focus on the location and duration of exposure, while a charterer or trader may need to understand how notification, delay or rerouting could affect the fixture. A financier or supply-chain team may be looking at the point where disruption could reach a transaction, delivery or production schedule.
The boundary is relevant because of what it changes for that decision, not because the line itself creates or removes the threat.
Risk can move before a boundary does
Designated areas bring consistency to decisions made by many organisations. That consistency is useful, but changing a boundary takes time and the threat can change first.
Pirate groups can extend their reach offshore. Missile or drone activity can create a threat for which a piracy-era boundary was never designed. GNSS interference can affect the approaches to a port or chokepoint without respecting an insurance or reporting line. A quiet period can also reduce the immediate threat without changing a standing commercial requirement.
This is why a boundary should be treated as one input to the assessment. The route still needs to be considered against current incidents, threat capability, official guidance, the vessel’s characteristics and the intended transit window.
Follow the route and the threat, not only the line
Before relying on an area designation, establish who issued it and what it is intended to do. Check that the coordinates and notice are current, then identify the reporting, insurance or planning consequence attached to them.
The next question is what the boundary does not answer. It may say nothing about the particular threat outside the line, the vessel’s profile, electronic interference, a recent incident or a change that occurred after the notice was issued.
Verihelm supports that wider view by bringing the planned route together with relevant incidents, approved assessments and changing threat areas. Voyage risk assessments are produced through the Verihelm platform, pass through Dryad Global’s internal quality-control process and carry a visible approval status. They inform the customer’s consideration of the voyage; they do not replace BMP Maritime Security, official reporting arrangements, insurance terms or the customer’s own operational and legal responsibilities.
A line can change what a vessel must report, prepare or insure. The route assessment explains what the vessel may face around it.
