The Offshore Ports (TOP) Concept
The Offshore Ports (TOP) concept introduces a structured and globally applicable framework aimed at recognising, organising, and coordinating offshore maritime activities beyond traditional port boundaries.
Modern offshore operations, including oil and gas production, renewable energy installations, subsea infrastructure, and ship-to-ship (STS) transfers have evolved into highly complex systems involving continuous movement of vessels, aircraft, personnel, and cargo. These activities take place in areas that function operationally as terminals, yet remain outside the formal definition, governance, and coordination mechanisms of conventional ports.
The TOP concept addresses this structural gap by establishing a unified framework that recognises offshore installations and operational zones as functional Offshore Ports, enabling a more integrated, safe, and efficient offshore operational environment.

Origin of the Offshore Ports (TOP) Initiative
The concept of The Offshore Ports (TOP) originated from direct engagement with port authorities and Search and Rescue (SAR) organisations across multiple jurisdictions.
During these discussions, a consistent challenge became evident: many authorities, regardless of their level of development, face significant budgetary constraints that limit their ability to expand or enhance critical safety and environmental services. This includes the provision of adequate SAR coverage, modern equipment and specialised response capabilities.
Recognising this gap, the idea emerged to establish a structured and sustainable mechanism through which additional funding could be generated to support these essential services. This led to the development of the TOP concept as a global initiative.
TOP is designed to complement existing governmental and international frameworks by introducing a systematic, industry-supported model. Through this approach, offshore operational activities contribute to a funding mechanism that can support:
- Countries with limited financial resources, where SAR and environmental capabilities are insufficient
- More developed regions, by reinforcing and enhancing existing systems
- The provision of specialised assets such as SAR helicopters, response vessels and trained emergency teams
The initiative builds on the principle that industries operating offshore already maintain high standards of safety and environmental responsibility. By structuring their contribution through a coordinated global framework, these efforts can be extended to deliver broader humanitarian and environmental benefits.
In this way, TOP aims to create a sustainable and equitable model that supports the protection of life at sea, strengthens emergency response capability and contributes to the preservation of the marine environment worldwide.
1. Introduction
The Offshore Ports (TOP) is an international private initiative proposing the development of a structured, coordinated and sustainable framework for offshore operations worldwide.
Offshore activities—including the transfer of passengers and cargo, vessel traffic, aviation operations and industrial works—are increasingly critical to the global energy, maritime and logistics sectors. However, these activities currently operate beyond conventional port limits without a unified international framework for coordination, technical assurance and sustainable support services.
2. The Challenge
Despite the existence of international conventions governing maritime safety and environmental protection, offshore operations remain:
- Fragmented across jurisdictions
- Dependent on inconsistent levels of Search and Rescue (SAR) coverage
- Lacking a unified system for technical coordination and oversight
- Exposed to environmental risks without a structured global response mechanism
- Increasingly complex due to growth in offshore energy and maritime traffic
This gap creates challenges in ensuring consistent safety standards, emergency response capability and environmental protection across offshore regions.
3. The TOP Concept
TOP proposes the recognition of offshore operational zones as an extension of the global port and transport system, supported by a coordinated and structured framework.
The initiative introduces:
The Offshore Ports (TOP) Concept Note
Towards a Global Framework for
Offshore Operations
- A harmonised operational frameworkfor offshore activities
- Coordination of vessel traffic, aviation and subsea operations
- A globally aligned technical assurance approach
- A transparent tariff-based funding mechanismlinked to offshore activity
- A structured model to support Search and Rescue (SAR)and environmental protection
This approach reflects established practices in port and aviation systems, adapted to the offshore environment.
5. Sustainable Industry Contribution
TOP introduces a structured mechanism through which offshore activities contribute to safety and environmental objectives.
A tariff-based contribution systemapplied to offshore operations—such as vessel movements, passenger and cargo transfer, and industrial activities—would generate sustainable funding to:
- Support and enhance existing governmental and international SAR services
- Strengthen emergency response capability in offshore regions
- Support monitoring, prevention and response to environmental risks
- Contribute to the preservation of marine life and ecosystems
This model reflects proven industry practices where stakeholders contribute to safety-critical services.
6. Role and Positioning
TOP is intended to evolve as an independent, international, industry-supported organisation.
It will:
- Complement existing governmental and international frameworks
- Support the implementation of recognised conventions and standards
- Provide a platform for cooperation between industry and authorities
- Promote best practices and operational consistency globally
TOP does not replace regulatory authorities but enhances coordination and practical implementation.
7. Path Forward
The development of TOP will be achieved through:
- Engagement with industry stakeholders and operators
- Dialogue with governmental and international organisations
- Development of guidance, frameworks and pilot applications
- Progressive adoption and recognition across offshore regions
8. Vision
To establish Offshore Ports (TOP) as a globally recognised framework that:
- Enhances safety and protects life at sea
- Strengthens Search and Rescue capability
- Improves coordination of offshore operations
- Supports sustainable industry contribution
- Protects the marine environment and biodiversity
4. Technical Assurance Approach
TOP promotes a coordinated technical assurance model across offshore operations.
- Operators retain responsibility for safety and compliance under applicable regulations
- Technical procedures are aligned with recognised international standards
- Independent verification is carried out by approved third-party bodies and classification societies
- TOP provides a framework for consistency, coordination and transparencyacross jurisdictions
This approach strengthens technical integrity without altering existing legal responsibilities.
Legal Context: National and International Waterways in Offshore Maritime Operations
The interaction between offshore maritime operations and the legal regimes governing national and international waterways presents a fundamental challenge within the current maritime framework. Under the United Nations Convention on the Law of the Sea (UNCLOS), a clear distinction is drawn between maritime zones subject to full coastal state sovereignty and those governed by international rights of navigation and overflight.
National waterways, comprising internal waters and the territorial sea, fall under the sovereignty of the coastal state. Within internal waters, the state exercises complete authority over all maritime activities. In the territorial sea, extending up to 12 nautical miles from the baseline, foreign vessels enjoy the right of innocent passages defined under Articles 17–32 of UNCLOS, subject to the regulatory authority of the coastal state.
Beyond the territorial sea, the exclusive economic zone (EEZ) and the continental shelf, governed under Articles 56 and 77 respectively, grant coastal states sovereign rights for the purpose of exploring, exploiting, conserving, and managing natural resources. However, these zones remain subject to freedoms of navigation and overflight by other states, thereby introducing a hybrid legal regime combining elements of national jurisdiction and international use.
In contrast, international waterways, particularly straits used for international navigation, are governed under the regime of transit passages established in Articles 37–44 of UNCLOS. These provisions ensure the uninterrupted passage of vessels and aircraft between one part of the high seas or EEZ and another, limiting the ability of coastal states to impede such movement while still recognising their role in ensuring safety and environmental protection.
Offshore installations and operations including oil and gas platforms, renewable energy infrastructure, ship-to-ship transfers, vessel traffics and offshore aviation logistics are frequently situated within or adjacent to these maritime zones. As such, they operate at the intersection of national sovereignty and international navigation rights. Despite functioning as critical operational nodes for the transfer of passengers, cargo, and services, these installations are neither formally classified as ports nor integrated within a unified regulatory framework that reflects their dual operational context.
This creates a fragmented legal and operational landscape in which offshore activities are subject to overlapping and, at times, conflicting jurisdictional regimes. The absence of a structured system becomes particularly evident in strategically sensitive regions and international waterways, where operational activities intersect with both coastal state authority and global navigation rights.
In this context, The Offshore Ports concept seeks to provide a systematised and cooperative frameworkcapable of bridging the divide between national and international maritime regimes. By introducing a structured approach to the recognition, regulation, and coordination of offshore operations, the framework aims to integrate these activities within both national jurisdictional systems and the broader international maritime order.
Such an approach has the potential to support fair and transparent contribution mechanisms, enhance maritime safety through coordinated Search and Rescue (SAR) systems, strengthen environmental protection, and promote the sustainable management of offshore operations. Importantly, it offers a model that aligns the interests of coastal states, maritime nations, and global stakeholders, ensuring that offshore activities are governed in a manner consistent with both sovereign rights and international obligations.
Industry funds SAR helicopter service for CNS
Assistant Lead Offshore Safety/Survival Instructor
August 16, 2015
North Sea oil and gas operators are funding a search and rescue (SAR) helicopter service to supplement national SAR cover for parts of the Central North Sea (CNS). The new service retains the SAR aircraft and crews previously provided by BP’s Jigsaw.
Industry stepped in to ensure rescue and recovery capabilities in the CNS were maintained after changes were announced by Government to the UK wide search and rescue service. These also coincided with Jigsaw moving off BP Miller platform to make way for decommissioning.
Robert Paterson, health and safety director at Oil & Gas UK, said: “Jigsaw provided an excellent service that has benefited many in the CNS over the years but the removal of the Miller platform meant the service was not sustainable. “Changes to national SAR provision also meant that rescue within two-hours might not have been achievable in the event of an en-route helicopter ditching in certain parts of the CNS. That is why operators of various fields in the CNS worked together and with Oil & Gas UK to find a solution.
This industry-funded search and rescue helicopter service based out of Aberdeen maintains the rescue and recovery capability we expect for our offshore workforce.”
