Key Takeaways:

  • PSC inspections verify compliance with international maritime regulations

  • Action codes indicate deficiency severity and required corrective measures

  • IMO has strengthened Port State jurisdiction over the past three decades

  • Risk-based inspection regimes focus resources on high-risk ships


Introduction to Port State Control (PSC)

Port State Control (PSC) is a vital mechanism in the maritime world, acting as a second line of defence against substandard shipping. It involves inspecting foreign ships at ports to check if they follow international rules set by IMO. Port state authorities carry out these inspections to ensure the ship, its equipment, and crew meet the necessary standards.


Purpose and Objectives of PSC Inspections

The main goal of PSC inspections is to spot and fix issues that could endanger the ship, its crew, and the sea environment. These inspections aim to reduce (or, even better, eliminate) substandard shipping and make sure all ships follow IMO rules.


Regular and consistent PSC inspections help enforce global maritime standards, preventing accidents and pollution caused by non-compliant ships.


The objectives of PSC inspections include:

  • Checking if ships follow safety and environmental protection rules

  • Finding and fixing issues that could risk the ship or its crew

  • Making sure ships are manned and run according to international standards

  • Ensuring a fair playing field for shipping by treating all ships equally


Role of PSC in Ensuring Maritime Safety and Environmental Protection

PSC plays a crucial role in ensuring maritime safety and safeguarding the marine environment. Through comprehensive inspections and the enforcement of international regulations, port states can identify and address the dangers posed by substandard shipping. PSC examines multiple aspects, such as the ship's structure, equipment, crew, and operational procedures, to ensure compliance with standards.


Collaboration is crucial for PSC's success. Memoranda of Understanding (MoUs) have been established in various regions to facilitate uniform inspections and information sharing. These agreements help avoid repeated inspections of ships and ensure adherence to global standards at ports worldwide.


"Port State Control is a critical tool for getting rid of substandard shipping and boosting maritime safety. Through teamwork and uniform inspections, we can enforce global rules and safeguard our oceans."

The role of PSC in keeping the seas safe and protecting the environment is huge. By being a second line of defence against non-compliant ships, PSC inspections play a big part in preventing accidents, pollution, and protecting marine life. As the shipping world keeps changing, PSC's role in keeping safety and environmental standards high will only grow.


Legal Framework and Regulatory Basis for PSC

The legal foundation for Port State Control (PSC) is rooted in international maritime law, with a key role for the United Nations Convention on the Law of the Sea (UNCLOS). Articles 218 and 219 of UNCLOS empower port States to enforce measures against unseaworthy vessels. This authority allows them to inspect and detain ships posing environmental threats or failing to meet safety and pollution standards.


IMO conventions such as SOLAS, MARPOL, STCW, and ILO conventions provide the framework for port States to verify certificates and conduct inspections. These instruments ensure compliance with international standards, safeguarding the marine environment and human life at sea.


International Conventions and IMO Regulations

The IMO has developed "Procedures for Port State Control" to guide and standardize PSC inspections globally. These procedures detail the selection of ships for inspection, the inspection process, and the reporting of deficiencies.


They focus on targeting high-risk vessels and ensuring consistent practices across port States.


Some of the IMO conventions which underpin PSC inspections include:

  • SOLAS 1974: Ensures the safety of merchant ships by setting minimum standards for construction, equipment, and operation.

  • MARPOL: Aims to prevent pollution from ships, covering oil, noxious liquid substances, harmful substances, sewage, garbage, and air pollution.

  • STCW 1978: Sets qualification standards for masters, officers, and watch personnel on seagoing merchant ships.

  • Load Lines (LL) 1966: Establishes uniform principles and rules regarding the limits to which ships on international voyages may be loaded.

  • Tonnage Measurement (TONNAGE) 1969: Provides a universal system for the tonnage measurement of ships.

  • Anti-Fouling Systems (AFS) 2001: Prohibits the use of harmful organisms in anti-fouling paints and establishes a mechanism to prevent the future use of harmful substances in anti-fouling systems.

  • Ballast Water Management (BWM) 2004: Aims to prevent the spread of harmful aquatic organisms from one region to another by establishing standards and procedures for the management and control of ships' ballast water and sediments.

Regional Memoranda of Understanding (MoUs) on PSC

Regional cooperation in PSC is facilitated by Memoranda of Understanding (MoUs). These agreements bring together maritime authorities from various countries to coordinate their PSC efforts. The goal is to eliminate sub-standard ships through harmonized inspections.


Currently, nine regional MoUs on PSC exist around the world, covering different geographical areas:

  1. Paris MoU: Europe and the North Atlantic

  2. Tokyo MoU: Asia and the Pacific

  3. Acuerdo de Viña del Mar: Latin America

  4. Caribbean MoU

  5. Abuja MoU: West and Central Africa

  6. Black Sea MoU

  7. Mediterranean MoU

  8. Indian Ocean MoU

  9. Riyadh MoU

Overview of PSC Inspection Process

The Port State Control (PSC) inspection process is vital for maritime safety and environmental protection. PSC officers (PSCOs) inspect foreign ships in their ports to check compliance with international laws. The Paris Memorandum of Understanding (Paris MoU) outlines definitions and abbreviations for PSC documents. This standardizes inspections across member states.


Selection Criteria for Ships to be Inspected

Ships are selected for PSC inspections based on risk factors. These include ship type, age, flag, and inspection history. The system aims to inspect high-risk ships more often while also conducting random checks. This ensures fairness for all vessels. The risk factor of a given vessel is also strongly associated with the flag it flies (it being white, grey or black listed).


Scope and Areas Covered During PSC Inspections

PSC inspections cover various areas to ensure safety and compliance. The initial check verifies certificates and documents and assesses the ship's condition. This includes the navigation bridge, engine room, and living spaces. Fire safety, life-saving appliances, and pollution prevention are also examined.


If a PSCO suspects non-compliance, a detailed inspection follows. This may involve operational controls and specific risk areas. Crew members must also demonstrate their knowledge of essential procedures and emergency responses.


Documentation and Certificates Verified by PSCOs

PSCOs check a range of certificates and documents during inspections. These ensure the ship meets international standards. The documents include:

  • Ship certificates (e.g., registration, tonnage, load line)

  • Crew certificates (e.g., competency, medical fitness)

  • Safety management and security certificates

  • Logbooks (e.g., deck, engine, oil record book)

  • Manuals and plans required by IMO conventions

PSC Action Codes and Their Significance

Port State Control (PSC) authorities employ a standardized system of action codes. These codes categorize the severity of deficiencies found during inspections. They indicate the necessary corrective measures. These codes are vital for maritime safety, environmental protection, and compliance with international regulations. The Paris MoU and other regional PSC regimes have established a detailed set of action codes. They guide ship operators and PSC officers in rectifying deficiencies and preventing hazards.


Categories of Deficiencies and Their Severity

Deficiencies found during PSC inspections are categorized based on their nature and severity. Common areas of concern include ship structure, fire safety, life-saving appliances, machinery, and pollution prevention. The severity of a deficiency determines the action code assigned to it. This ranges from minor issues to major non-conformities that may warrant immediate detention.


Explanation of Each Action Code and Its Implications

Each action code has specific implications for the ship and its crew. For instance, Code 17 instructs the master to rectify a deficiency before departure. This may require a second inspection to verify compliance. Code 19 pertains to major ISM-related deficiencies that pose a serious threat and must be resolved before departure. On the other hand, Code 16 allows for the rectification of minor deficiencies within 14 days after departure.



The most severe action code, Code 30, signifies grounds for detention. This means the ship will be detained until the deficiencies are rectified. Code 35 is used when a ship is allowed to sail after a detention. Codes 40 and 45 involve informing the next port of call to check and rectify deficiencies or re-detain the ship if necessary. Codes 50 and 55 require informing or consulting with the flag State or Consul when a ship is detained or when relevant deficiencies are found.


Statistical Comparison of Action Codes Imposed during Inspections

A comparison of PSC statistics from different MoUs reveals variations in the use of action codes and detention rates. The Paris MoU, for example, has consistently recorded higher detention rates compared to the Tokyo MoU. Both regimes share similar patterns in terms of the most frequently observed deficiencies and the action codes imposed.
