Solutions for Shallow Hazards

Our practitioners leverage high-resolution geophysical and seismic data to assess offshore geohazards. These data sets serve as foundations for seafloor and subsurface interpretation for assessments of shallow hazards.

We specialize in the following:

  • Identifying shallow hazards that could impact the integrity of the proposed infrastructure
  • Assessing seafloor conditions, assessing stratigraphic character, and analyzing geologic processes
  • Interpreting and mapping geologic and anthropogenic constraints using high-resolution geophysical and seismic data sets, including two-dimensional and three-dimensional data
  • Evaluating wellsite locations, mooring spreads, anchor locations, pipeline and cable routing corridors, wind farm sites, and foundation zones
  • Creating comprehensive maps that depict water depth, topography, shallow structures, and seafloor and subsurface geologic conditions
  • Preparing reports required for permit applications to government and insurance agencies to streamline approval

Desktop and Planning Solutions

A desktop study can provide a comprehensive preliminary analysis of a potential exploration or development site. Such studies often combine proprietary and public data to help plan for wells, pipeline routing corridors, or wind energy areas.

Planning studies, which often build on desktop studies, offer nuanced understandings of the seafloor, shallow stratigraphy, and soil conditions and how these conditions could impact the selection of pipeline routes and other seabed infrastructure. We have access to many Geographic Information Systems (GIS) platforms, empowering us to efficiently manage project data while remaining flexible in our application and client support.

We support clients in the following ways:

  • Feasibility studies to address site or route corridor conditions
  • Front-end engineering and design (FEED) studies
  • Optimized scope of future site investigations
  • Foundation alternatives for conceptual design
  • Span analysis input data for pipeline designers
  • Risk assessments to address potential adverse effects on siting, design, construction, and operation

Integrated Solutions

Clients turn to our multidisciplinary team for their most complex offshore projects. Depending on analysis type, subsea structures, our clients’ requests, and data availability, we integrate geological, geophysical, geotechnical, and archaeological data to better understand the depositional history, stratigraphy, and geohazards.

Working together, our multidisciplinary staff builds best-value solutions that expedite project completion, identify potential design constraints early-on, support best-value solutions, and optimize the scope of geophysical and geotechnical surveys.

Capabilities

  • Defining the stratigraphic section using seismic data to mitigate shallow exploratory drilling risks
  • Providing pipeline routing and field layout guidance using existing archaeological, geophysical and geotechnical data
  • Managing project data and infrastructure in GIS formats
  • Interpreting geologic and geotechnical parameters that define the spatial and temporal processes affecting foundation design of facilities interacting with the seafloor and shallow subsurface
  • Developing three-dimensional geologic models to better define seafloor and subsurface conditions and constraints
  • Documenting the geologic setting and processes, as well as the geotechnical properties of the subsurface soils
  • Planning and optimizing the scope of the geophysical and geotechnical field and laboratory programs using all existing geoscience and engineering data
  • Conducting detailed analyses and design of foundation elements
  • Analyzing, evaluating, and recommending drilling and foundation locations and types, avoiding geohazards that pose costly installation and foundation risks
