Executive Summary:
The global maritime security environment remained elevated this week, characterised by the continued convergence of armed conflict, maritime crime and geopolitical competition. The most significant concern was the persistence of threats to commercial shipping in the Middle East, where repeated incidents around a major regional chokepoint demonstrated that vessels remain exposed even during routine transits. Developments further south indicate that this risk is not confined to a single corridor, with renewed hostile activity near the Bab el-Mandeb adding pressure to an already constrained operating environment.
In Europe, the maritime dimension of the Russia-Ukraine conflict continued to expand the range of risks facing commercial vessels, particularly those operating in and around Black Sea ports. At the same time, the week demonstrated that more conventional maritime security threats remain relevant: a deadly piracy incident off Somalia represented a marked deterioration in the consequences of piracy, while attempted boardings in Southeast Asia and West Africa reflected persistent opportunistic crime.
Overall, the week's incidents reinforce an increasingly fragmented threat landscape in which commercial vessels face different but overlapping risks depending on their operating region. Conflict-related attacks remain the dominant concern, while piracy, robbery and grey-zone activity continue to require sustained vigilance.
Major Incidents Include:
STRAIT OF HORMUZ:
Sustained Projectile Campaign Against Tankers: Eight tankers were struck by unknown projectiles in the Strait. The strikes caused fires, a blackout and engine room damage. No casualties have been reported and no actor has claimed responsibility, but the frequency of attacks points to a severe and ongoing threat to commercial shipping in the corridor.
EUROPE:
Black Sea: Escalating Strikes on Merchant Shipping: Ukrainian drones disabled the bulk carrier Aroyat near Novorossiysk, leaving one Turkish crew member missing. Russian forces struck a Liberian-flagged cargo vessel in an Odesa-region port, killing one crew member, which underscores the lethal risk to shipping serving both Russian and Ukrainian ports.
GULF OF ADEN:
Deadly Turn in Somali Piracy: Pirates killed five crew members of the hijacked tanker Honour 25 before Puntland forces retook the vessel. These are reportedly the first crew deaths at the hands of Somali pirates in over a decade, marking a significant escalation in violence against hostage crews.
RED SEA:
Attempted Attack Near Bab el-Mandeb: A tanker reported multiple explosions close to the vessel about 60NM south of Al Mukha. The attack is likely attributable to the Houthis and came amid a Saudi-backed government offensive in Yemen, raising the risk to vessels transiting the southern Red Sea.
Europe:
28 September / UAV Strike:
Ukrainian drones reportedly struck a bulk carrier approaching Novorossiysk, causing a major fire and disabling the vessel. One Turkish crew member remains missing, and the other 15 were rescued. Ukraine has not claimed the attack.
30 September / Strike:
Ukrainian forces struck a target in the Black Sea, reportedly a Russian vessel. The target may have been an oil tanker. The vessel's identity, flag, location and the extent of damage remain unconfirmed, and Russia has not acknowledged the attack.
3 October / Strike:
One crew member was killed and three were injured when Russian forces struck a Liberian-flagged cargo vessel in a port in the Odesa region. The vessel's name, the extent of damage and the weapon used have not been disclosed.
Strait of Hormuz and Gulf of Aden:
28 September / Strike:
A suspected unknown projectile struck a Crude Oil Tanker, causing a fire that was later extinguished. No major consequences have been reported. The source of the projectile has not been identified.
29 September / Strike:
An unknown projectile struck the crude oil tanker Mersin Prosperity on its port side while it was transiting the Strait of Hormuz. Damage, casualties and the source of the projectile remain unconfirmed.
29 September / Strike:
A tanker was struck by an unknown projectile during an inbound transit of the Strait of Hormuz. Damage, casualties and attribution remain unconfirmed. The vessel may have been involved in shuttle operations to tankers waiting south of the Strait.
29 September / Strike:
An unidentified tanker was struck by an unknown projectile in the Strait of Hormuz. The vessel's identity, damage, casualties and attribution remain unconfirmed.
29 September / Piracy:
Five crew members of a petroleum tanker were killed by Somali pirates before Puntland security forces retook the vessel, which had been held off the Somali coast since April. Four other crew members were injured.
1 October / Strike:
An unidentified tanker was struck by an unknown projectile, resulting in a fire. The crew are reported safe, while damage and environmental impact remain unknown.
2 October / Strike:
An unidentified tanker was struck by an unknown projectile during an outbound transit of the Strait of Hormuz, causing a small fire and a blackout onboard. No casualties were reported, and the vessel has resumed transit. Attribution remains unknown.
2 October / Strike:
An unidentified crude oil tanker was struck on its port side by an unknown projectile. All crew are reported safe, and no environmental impact has been reported. Attribution remains unknown, and the incident is under investigation.
4 October / Strike:
An unidentified tanker was struck by an unknown projectile, causing damage to the engine room. The crew are reported safe, and no environmental impact has been reported. Attribution remains unknown, and the incident is under investigation.
Red Sea:
4 October / War Risk:
A tanker reported multiple explosions in close proximity to the vessel. The crew are reported safe, and no damage or environmental impact has been reported. The incident is assessed as an attempted attack, likely by the Houthis.
Singapore Strait:
30 September / Robbery:
Four unarmed perpetrators boarded a bulk carrier and were sighted in the engine room while the vessel was transiting the Phillip Channel. The crew are safe and nothing was stolen.
Gulf of Guinea:
30 September / Robbery:
A suspected sea robber boarded a container ship at Monrovia Anchorage, Liberia, and was sighted by the crew on the port side of the vessel. No crew injuries were reported, and local authorities and the Coast Guard boarded the vessel to investigate.
Caribbean:
4 October / Drug Smuggling:
Four people were killed when US forces struck a go-fast vessel allegedly involved in drug trafficking. The military released video of the strike but provided no evidence that the vessel was carrying drugs.
Operational Guidance
Operators Should:
Watch for Air & Sea Projectiles: Maintain sharp lookouts for UAVs, missiles and USVs in the Strait of Hormuz, the southern Red Sea and the Black Sea, particularly near Russian and Ukrainian ports.
Reassess Chokepoint Transits: Transit the Strait of Hormuz and Bab el-Mandeb only when necessary and authorised, and report any suspicious activity to UKMTO and MSCIO immediately.
Harden Vessels Against Boarding: Apply BMP-MS measures off Somalia. Secure engine rooms, store rooms and access points at anchorages and in the Singapore Strait, especially at night.
Threat Assessment
Region | Threat Level | Assessment |
Europe (Black Sea) | Extremely High | Commercial shipping remains exposed to the wider Russia-Ukraine conflict, with the risk of collateral or deliberate attacks increasing around conflict-affected ports and approaches. The operating environment remains unpredictable for vessels serving both sides of the conflict. |
Red Sea | High | The threat of hostile action against commercial vessels remains significant, particularly around the southern Red Sea and Bab el-Mandeb. The persistence of regional conflict and maritime targeting creates an elevated risk even where individual attacks do not result in damage or casualties. |
South China Sea | Low | Regional maritime tensions and grey-zone activity remain present, but the activity recorded this week does not indicate a significant direct threat to commercial shipping. The principal concern remains the broader potential for continued maritime friction. |
Strait of Hormuz and Gulf of Aden | Extremely High | Strait of Hormuz: Sustained and repeated attacks against commercial shipping indicate a highly unstable operating environment. The frequency of incidents, uncertainty over attribution, and exposure of vessels during transit create a persistent and difficult-to-mitigate threat. Gulf of Aden: Piracy remains a serious threat, with the week's developments demonstrating that successful hijackings can carry substantially more severe consequences for crews than in recent years. The persistence of pirate activity warrants heightened protective measures. |
Caribbean | Low | Maritime security concerns this week were primarily associated with counter-crime operations rather than a direct threat to commercial shipping. The broader security environment warrants monitoring, but the reported activity does not indicate a heightened commercial maritime threat. |
Gulf of Guinea | Moderate | Maritime crime continues to present a tangible risk to vessels, particularly around anchorages. However, the threat remains predominantly opportunistic and considerably less severe than the conflict-driven risks affecting the Middle East and Black Sea. |
Singapore Strait | Moderate | The principal concern remains opportunistic maritime crime rather than conflict-related violence. Boarding risks persist in heavily trafficked waters, particularly where vessels may be vulnerable during transit, although the overall severity remains comparatively limited |
