Unlike Panama, Suez, or Bosporus — the Cape has no transit toll. But SAMSA runs active PSC inspections at Durban, Cape Town, Richards Bay, and Port Elizabeth. Here's what triggers action.
Marine Notice 12 of 2008 requires all vessels calling South African ports to file an ISPS pre-arrival message at least 96 hours in advance. The message must include ISSC details, current security level, and last 10 port calls with security levels at each. Missing or late submissions result in port entry denial.
All vessels 500 GT and above on international voyages must hold a valid International Ship Security Certificate (ISSC) issued by their flag state. SAMSA inspectors verify ISSC validity, Ship Security Plan currency, and security drills log during PSC inspections. An expired ISSC is automatic grounds for detention.
A designated SSO must be on board for all international voyages. The SSO must hold a valid SSO certificate recognised by the flag state. SAMSA PSC inspectors routinely check SSO certification and interview the officer. Acting SSOs without certification are a deficiency trigger — particularly at Durban, which has elevated inspection rates.
The pre-arrival ISPS message must list the last 10 ports of call with dates and the security level in effect at each port. Gaps in this record — or ports where security level is listed as unknown — are flagged by SAMSA's system. If any previous port was at Security Level 2 or 3, additional supporting documentation is required.
The SSP must be kept current and approved by the flag state. SAMSA inspectors check SSP approval date, confirm the plan includes Cape route-specific threat assessments if applicable, and verify it has been reviewed following any security incident in the past 12 months. Outdated SSPs are among the top 3 IOMOU deficiency categories.
Vessels calling Durban (the Cape's primary commercial port) face the region's most active PSC inspection regime. SAMSA participates in the Indian Ocean MOU (IOMOU) which enables coordinated targeting of high-risk vessels. Deficiencies found at any IOMOU port are visible to South African PSC officers before your vessel arrives.
Requirements for vessels calling South African ports on the Cape route. Vessels transiting without calling a South African port have no SAMSA pre-arrival obligation, but must maintain valid ISPS documentation.

SAMSA operates under the Indian Ocean MOU — deficiencies follow your vessel's flag record across the region. These are the real detention triggers.
A single inspection recorded 42 deficiencies. Combined ISPS, ISM, fire safety, and structural findings. Vessel detained for 5 days at Durban. Off-hire cost estimated at $180,000+ before the deficiency list was cleared. The inspection was triggered by a late pre-arrival message.
The top detention category in the IOMOU region. Expired ISSC, missing SSO certificate, outdated Ship Security Plan, and incomplete port call records account for over 30% of all Cape-area detentions. South African PSC inspectors prioritise security documentation above structural deficiencies.
A PSC detention at Durban averages 3–7 days to clear deficiencies. At $20,000–$40,000/day off-hire for a typical bulk carrier, a single detention event costs $60,000–$280,000 before port fees, re-inspection charges, and commercial penalties for late delivery.
South Africa participates in the Indian Ocean MOU (IOMOU) covering 23 member states. Any deficiency recorded at an IOMOU port follows your vessel's flag record and becomes visible to inspectors at subsequent IOMOU port calls — including Durban, Port Elizabeth, Cape Town, and Richards Bay. A bad inspection in Colombo increases your targeting probability at the Cape.
In November 2025, the bulk carrier Sea Lord arrived at Durban following a Cape of Good Hope transit from Europe. The vessel filed its SAMSA ISPS pre-arrival message 71 hours before arrival — 25 hours short of the 96-hour requirement under Marine Notice 12 of 2008.
The late filing triggered a targeted PSC inspection. Inspectors found 42 individual deficiencies across security documentation, fire detection equipment, ISM non-conformities, and crew certification records. The vessel was detained under SOLAS and ISPS Code provisions.
The 5-day detention to clear deficiencies and pass re-inspection resulted in estimated off-hire costs exceeding $180,000, not including port fees, re-inspection charges, and contractual penalties for late cargo delivery. The initial trigger was a filing deadline missed by 25 hours.
