Key Developments

  • West Africa: Attempted boarding incident at Abidjan Anchorage demonstrates continued security risks at major West African ports. Crew alertness successfully deterred the intrusion attempt.
  • Southeast Asia: Unusually quiet week in Southeast Asia with zero reported incidents, though historical patterns suggest this may indicate underreporting rather than improved security conditions.
  • Indian Ocean: No incidents reported this week in Indian Ocean region, but substantial threat level remains due to ongoing Houthi activities and regional instability.
  • Global: Overall maritime security incidents significantly lower than typical weekly averages, with only one reported incident across all monitored regions.

7-Day Forecast

  • West Africa: High likelihood of continued boarding attempts and piracy activities in Gulf of Guinea, particularly around major anchorages including Abidjan, Lagos, and Cotonou. Vessels should maintain enhanced watch schedules and implement anti-boarding measures when anchored.
  • Southeast Asia: Expected increase in robbery and theft incidents in Singapore Strait and Malacca Strait following typical weekly patterns. Ships transiting should increase vigilance during night hours and maintain continuous radar watch.
  • Indian Ocean: Significant probability of renewed Houthi missile and drone attacks in Red Sea corridor and Bab el-Mandeb Strait. Vessels advised to coordinate with naval forces and consider alternative routing via Cape of Good Hope.
  • Europe: Low probability of security incidents expected to continue with stable conditions in Mediterranean and North Sea regions. Routine security protocols sufficient for most commercial traffic.
  • Americas: Minimal security threats anticipated across Caribbean and South American waters with continued low threat environment. Standard maritime security measures adequate for regional operations.

Incident Details

Description

Seven unauthorized persons armed with knives boarded a Tanker while underway and entered the engine room. The crew raised the alarm, made a public address announcement, mustered, and conducted a search of the vessel. The incident was reported to Vessel Traffic Information Service (VTIS) and Singapore Coast Guard, who subsequently escorted the vessel. All crew members remained safe and no items were reported stolen.

Response Actions

  • Self-defense Measures
  • None Mentioned

Analysis

Key Findings

This incident demonstrates a coordinated boarding operation with the attackers specifically targeting the engine room, suggesting knowledge of vessel layouts and critical systems. The use of seven attackers indicates a well-organized group capable of controlling multiple areas of the vessel simultaneously. The crew's rapid response through alarm activation, public address announcements, and immediate mustering proved effective in deterring the attackers from completing their objectives. The quick coordination with VTIS and Singapore Coast Guard, resulting in immediate escort services, highlights the effectiveness of established maritime security protocols in high-traffic areas.

Recommendations

  • Implement enhanced engine room security measures including restricted access controls and additional monitoring systems
  • Conduct regular crew drills focusing on rapid response procedures for unauthorized boarding situations
  • Maintain continuous communication readiness with local maritime authorities when transiting high-risk areas

Description

US Naval Forces targeted up to three Iranian vessels anchored off Bandar Lengeh and Bandar Kong, Iran. While the exact time and location remain unspecified, circulating images suggest potential damage to civilian vessels, though this cannot be confirmed due to unclear imagery. Video footage shows what appears to be an Iranian warship on fire following the strike.

Response Actions

  • Self-defense Measures
  • None Mentioned

Analysis

Key Findings

This incident represents a significant escalation involving direct US naval engagement against Iranian vessels in Iranian territorial waters. The targeting of anchored vessels suggests a deliberate strike rather than a defensive engagement, indicating pre-planned military action. The uncertainty regarding civilian vessel involvement raises concerns about collateral damage and potential violations of maritime law. The fact that an Iranian warship was visibly damaged and set ablaze demonstrates the effectiveness of the US strike capability, while the anchored status of the targets suggests they were caught unprepared for defensive action.

Recommendations

  • Civilian vessels should avoid anchoring near military installations or naval vessels in areas of heightened tension
  • Maintain enhanced situational awareness and monitoring of military communications when transiting Iranian waters
  • Consider alternative anchorage areas away from potential military targets during periods of US-Iran tensions

Description

U.S. Forces seized a Tanker in the Caribbean Sea on January 20, 2026. The U.S. Southern Command stated the vessel was "operating in defiance of President Trump's established quarantine of sanctioned vessels" and was seized "without incident." The exact time and location of the seizure were not specified.

Response Actions

  • Self-defense Measures
  • None Mentioned

Analysis

Key Findings

This incident represents a significant escalation in maritime enforcement operations, with U.S. military forces directly seizing a commercial vessel for sanctions violations rather than relying on traditional interdiction or port state control measures. The reference to a "quarantine of sanctioned vessels" suggests a new enforcement framework that may involve active maritime exclusion zones or enhanced monitoring of designated vessels. The peaceful nature of the seizure ("without incident") indicates either the vessel crew offered no resistance or U.S. forces employed overwhelming tactical superiority to ensure compliance.

Recommendations

  • Vessel operators should verify their sanctions compliance status and avoid operating in areas where enforcement quarantines may be active
  • Maintain clear documentation of cargo origins, destinations, and ownership to demonstrate compliance with international sanctions regimes
  • Monitor official maritime security bulletins for updates on enforcement zones or quarantine areas that may affect transit routes

Incident Details

Description

Novorossiysk Port, Russia, was targeted by an Unmanned Aerial Vehicle (UAV) attack from Ukraine. The UAVs primarily targeted the Sheshkharis oil terminal, damaging six of seven oil loading berths. Additional reports indicate that a Russian warship, a radar guidance system, and a Pantsir-S2 air defence system also sustained damage during the attack.

Response Actions

  • Self-defense Measures
  • None Mentioned

Stolen Items

  • Other Items (Undersea Cable Infrastructure Damage)

Analysis

Key Findings

This attack demonstrates Ukraine's expanding capability to conduct long-range precision strikes against critical maritime infrastructure deep within Russian territory. The targeting of the Sheshkharis oil terminal's loading berths represents a strategic effort to disrupt Russia's energy export capabilities, with six of seven berths damaged indicating either multiple coordinated strikes or highly effective munitions. The collateral damage to military assets including a warship, radar system, and Pantsir-S2 air defense system suggests either the presence of naval vessels at the commercial port or the UAVs' ability to engage multiple target types during a single operation. The successful penetration of Russian airspace to reach Novorossiysk, a major Black Sea port, highlights potential gaps in Russia's layered air defense network or the evolution of Ukrainian UAV technology to overcome existing countermeasures. The damage to the Pantsir-S2 system is particularly significant as it represents the failure of point defense systems specifically designed to counter such threats.

Recommendations

  • Enhance layered air defense systems around critical port infrastructure with overlapping coverage zones
  • Implement rapid damage assessment and emergency response protocols for oil terminal facilities
  • Consider dispersing critical maritime operations across multiple facilities to reduce single-point-of-failure vulnerabilities
