A Vessel Hardening Vulnerability Assessment (VHVA) is a detailed assessment of a vessel’s physical and procedural security arrangements before operating in a higher-risk environment.
Castor Vali works with the Master and key vessel personnel to review the vessel’s general arrangement (GA) layout, existing hardening and security procedures, identify vulnerabilities and recommend practical measures to improve protection.
Particular consideration is given to whether the vessel can detect, deter and delay attempted boarding and safely implement its lockdown and crisis-response procedures.
A vessel entering the Voluntary Reporting Area (VRA), and most certainly the High-Risk Area, that has not previously been hardened should undergo a Vessel Hardening Vulnerability Assessment before entering the area.
Where a vessel has previously been assessed, Castor Vali recommends a new assessment where the existing VHVA is more than 12 months old. Vessel arrangements change over time. Hardening measures can be removed or degraded, equipment can change and crews rotate, meaning an older assessment may no longer accurately reflect the vessel’s preparedness.
The preferred approach is a physical onboard assessment by a Castor Vali vessel-hardening specialist working directly with the Master and key vessel personnel.
Typically, Castor Vali requires approximately two days onboard and, wherever possible, recommends conducting the assessment at the vessel’s last safe port before entering the higher-risk area. This provides time for any required stores to be sourced and recommended fabrication or other hardening work to be completed before sailing.
A desktop assessment can be undertaken where circumstances require it, but an onboard assessment provides a substantially better understanding of the vessel and its actual vulnerabilities.
The assessment considers the vessel as a complete security system rather than looking at individual hardening measures in isolation.
This can include access points, doors, hatches and portholes, locking arrangements, external hardening, access control, the vessel’s ability to lock down, communications and the location and suitability of the citadel or safe haven.
Where a citadel is required, consideration is also given to forced-entry protection, independent communications, crew accountability, medical provision, food, water, sanitation and other requirements necessary for it to function effectively during an incident.
It should not. Safety takes precedence over security.
All recommendations are considered against the vessel’s configuration, operation and HSE requirements. Hardening should provide effective security without introducing unacceptable safety risks or preventing the vessel and crew from carrying out their normal functions.
Where a preferred hardening measure is not practical because of the vessel’s design or operational requirements, alternative solutions can be considered.
No. Castor Vali identifies vulnerabilities and advises the vessel on the hardening measures required, but welding, hot work and specialist fabrication remain the responsibility of the vessel, owner or their appointed contractors.
Key findings and recommendations are discussed directly with the Master and officers during the assessment, allowing work to begin where necessary before the final report is issued.
If Castor Vali personnel subsequently embark on the vessel’s transit or offshore project, they can assist the crew with the implementation and maintenance of practical hardening measures that do not require specialist fabrication.
Under normal circumstances, Castor Vali provides the full Vessel Hardening Vulnerability Assessment report within 72 hours of completing the onboard assessment.
The report identifies the vessel’s principal vulnerabilities and provides practical recommendations for addressing them. Where appropriate, this includes photographs and diagrams to assist with fabrication or installation, requirements for transit and static operations, prioritised actions and a hardening stores list.
Key findings are also discussed directly with the Master and officers before the assessor leaves the vessel so that urgent actions do not have to wait for the written report.
Castor Vali’s Vessel Hardening Vulnerability Assessments take account of recognised maritime security requirements and guidance, including Best Management Practice Maritime Security, the International Ship and Port Facility Security (ISPS) Code and SOLAS, together with the prevailing threat environment, vessel-specific requirements and Castor Vali’s operational experience.
Recommendations are developed in consultation with the Master and with vessel safety remaining the overriding consideration.
