Subsea Preparedness Engineering Studies

A structured pathway to source control preparedness

Engineering studies provide the technical foundation for source control preparedness. They help operators understand potential well control scenarios, assess source control options and evaluate the technical and operational considerations that may influence response planning.

Rather than existing as standalone assessments, engineering studies often build upon one another, creating a structured pathway from understanding a potential release scenario through to identifying source control options and developing long-term well kill strategies. This progression helps organisations develop a stronger understanding of how technical decisions made during preparedness can influence response options and operational planning.

The graphic below illustrates a typical engineering studies pathway, beginning with Worst Case Discharge (WCD) analysis and progressing through well integrity assessments, source control analysis, execution planning and relief well design.

Engineering studies build upon one another, helping operators progress from understanding potential release scenarios through to developing source control options, execution plans and permanent well kill strategies.

Key facts

Engineering studies support source control preparedness by assessing potential well control scenarios.
Studies may include Worst Case Discharge (WCD), well integrity, plume modelling, capping analysis and relief well planning.
WCD studies help estimate the maximum credible flow rate from a blowout scenario.
Technical assessments inform emergency response planning, logistics execution planning and response strategies.
Engineering studies can be tailored to specific assets, wells and operating environments.
Findings help operators evaluate source control options before an incident occurs.

Engineering studies we support

Worst Case Discharge (WCD)

Assesses the maximum credible flow rate and behaviour of a potential blowout. Results inform source control planning and subsequent engineering studies.

Well integrity assessments

Reviews well design and integrity to support source control option selection and planning activities.

Structural integrity analysis

Evaluates well infrastructure and potential installation constraints for source control operations.

Plume and Computational Fluid Dynamics (CFD) studies

Examines plume behaviour and operational constraints to support source control planning and offshore operations.

Capping and containment analysis

Assesses capping and containment approaches to support response planning and procedure development.

Relief well planning

Develops relief well concepts and modelling to support long-term source control strategies.

Understand potential response challenges

Engineering studies help operators understand potential well control scenarios, source control options and operational constraints that may influence response planning.

Inform planning and preparedness activities

Technical assessments provide inputs that support emergency response planning, logistics preparation and response strategy development.

Support the source control lifecycle

From WCD analysis through to relief well planning, engineering studies provide technical insight at each stage of the source control lifecycle, helping organisations build preparedness progressively over time.

FAQs

: Engineering studies can support different stages of source control preparedness and may include WCD studies, well integrity assessments, structural integrity analysis, plume and CFD studies, capping and containment analysis, and relief well planning.
: Engineering studies provide technical information that can be used to support source control planning, response strategy development and preparedness activities.
: Yes. Engineering studies are based on asset-specific data, operating conditions and source control considerations to provide relevant technical inputs for preparedness and response planning.
: Engineering studies provide technical inputs that help inform response strategies, planning assumptions and source control decision-making within a SCERP.
