The expertise behind preparedness, readiness and response
Subsea preparedness and response often rely on specialist expertise that sits beyond a single organisation.
The Global Subsea Response Network (GSRN) brings together recognised organisations from across multiple technical and operational disciplines, helping strengthen preparedness activities, readiness initiatives and response capability throughout the source control lifecycle.
Rather than acting as a standalone service provider, GSRN helps connect operators with specialist expertise that supports source control planning, engineering activities, exercises, mobilisation and operational response support.

Well engineering and technical advisory provides access to specialist expertise that supports the technical foundation of source control preparedness and response. This capability helps organisations understand potential well control scenarios through source control studies, well engineering assessments and technical analysis, enabling informed decision-making before and during an incident. Support may include the development of response strategies, evaluation of intervention options and technical advisory services to strengthen preparedness arrangements and response planning.
Partner Organisations: WellCTRL, THREE60

Subsea intervention and inspection support the planning and execution of subsea activities that may be required during a source control response. Drawing on specialist intervention expertise, this approach can help organisations assess subsea conditions, support remotely operated vehicle (ROV) operations, conduct inspection and survey activities, and provide operational guidance for intervention planning. These services contribute to improved situational awareness and help establish the information needed to support effective response decision-making.

Marine operations provides specialist support for the offshore activities that underpin subsea response execution. This capability includes vessel coordination, offshore logistics, deployment planning and marine operational support, helping organisations manage the complex interfaces between vessels, personnel, equipment and offshore work activities. By bringing together marine expertise and operational oversight, it helps support safe, coordinated and efficient offshore response operations.

-
Environmental monitoring provides access to specialist expertise that helps organisations assess and understand environmental conditions before, during and after a response. Support may include environmental assessments, monitoring activities, field data collection and analysis, and technical guidance to inform response decisions. By delivering reliable environmental information, this feature enables organisations to maintain situational awareness and better understanding of potential impacts throughout the response lifecycle.
Partner Organisation: Continental Shelf Associates (CSA)
-
Logistics and mobilisation focus on the practical arrangements required to move personnel, equipment and resources to where they are needed. This service supports mobilisation planning, logistics coordination, deployment pathway development and operational support activities, helping organisations identify and address potential mobilisation challenges before an incident occurs. Effective logistics planning can help reduce delays, improve coordination and strengthen overall response readiness.
Partner Organisations: Intermoor

Exercise and preparedness support helps organisations validate plans, test assumptions and strengthen source control preparedness through structured training and assurance activities. Services may include exercise development, scenario design, ROV simulation, preparedness validation and assurance reviews tailored to specific operational requirements. By testing plans, people and processes in realistic scenarios, this capability helps build confidence in preparedness arrangements and identify opportunities for continuous improvement.
GRi Simulations
Supporting preparedness through ROV simulation, exercise development and scenario validation. GRi helps operators test plans, validate assumptions and build confidence in preparedness arrangements through realistic simulation environments.
Capabilities:
- ROV simulation
- Exercise design
- Scenario development
- Preparedness validation
Why specialist expertise matters
- Source control preparedness and response relies on multiple specialist capabilities working together.
- Engineering expertise, subsea intervention and inspection, marine operations, environmental monitoring, logistics and mobilisation, and exercise support all contribute to strengthening preparedness, supporting readiness activities and enabling an effective response when required.
- The Global Subsea Response Network (GSRN) helps connect operators with recognised specialist organisations across these disciplines, providing access to expertise throughout the source control lifecycle.
