Metocean

CSA Ocean Sciences Inc. (CSA) offers industry-leading metocean services designed for the unique demands of offshore energy development and deep-sea resource extraction. Our systems provide real-time environmental intelligence to improve operational safety, reduce downtime, and support engineering design for installations ranging from floating production systems and subsea mining vehicles to offshore wind farms and both cable and pipeline corridors. With decades of experience deploying systems from nearshore to ultra-deep marine environments, we offer fully integrated solutions including monitoring system design, mooring and equipment fabrication, deployment, maintenance, data acquisition, QA/QC, and regulatory-compliant reporting.

Metocean Services

Why Choose CSA for Metocean Studies

Our fully integrated turnkey services encompass program design and engineering, instrumentation selection, mooring and equipment fabrication, deployment and installation, maintenance and servicing, recovery operations, analysis and regulatory-grade reporting. CSA’s monitoring systems are built for reliability in demanding marine environments, from shallow coastal basins to ultra-deep moorings exceeding 6,000 m water depth.

Combined with our capabilities in metocean analysis, numerical modeling, and environmental forecasting, we provide seamless integration of real-time data into operational planning, engineering assessments, asset integrity programs, dynamic positioning systems, and shore-based decision-support platforms, helping clients reduce risk, improve efficiency, and make informed decisions throughout the project lifecycle.

Extended Capabilities

Deepwater & Ultra-Deepwater Mooring Experience

Shallow coastal inlets and abyssal plains require fundamentally different mooring engineering, and CSA has designed and operated systems across that full range. Our deepwater track record includes:

Clarion Clipperton Zone, Pacific Ocean (since 2019): Design, fabrication, and deployment of subsurface metocean buoy arrays in water depths up to 6,000 m for deep ocean mineral exploration, instrumented with acoustic Doppler current profilers and sensors for currents, waves, temperature, conductivity, dissolved oxygen, suspended sediments, and pH.

Western Pacific, Japan (ongoing): Oceanographic moorings and full water-column profiling to 5,500 m, compliant with draft International Seabed Authority (ISA) current-measurement guidelines, supporting Environmental Baseline Survey work for deep-sea mineral extraction.

Standards-based design: Extreme current profiles and mooring design criteria developed to offshore engineering standards, using ocean reanalysis datasets.

This deepwater capability is backed by the same turnkey delivery model we apply at every stage of engineering, fabrication, deployment, servicing, recovery, data analysis and reporting. Clients work with one accountable team from concept through final report, regardless of water depth.

Subsurface Monitoring
  • Currents and Turbulence: Acoustic Doppler current profilers for vertical current profiling from shallow coastal waters to ultra-deep (6,000 m) moorings.
  • Water Column Profiling: Multi-parameter conductivity-temperature-depth (CTD) sensors measuring temperature, salinity, dissolved oxygen, turbidity, fluorometry, and pH.
  • Wave Measurements: Directional wave buoys and bottom-mounted recorders for wave height, period, direction, and spectral energy.
  • Hydroacoustic Surveys: Towed, buoyed, moored, and autonomous acoustic systems for baseline monitoring, compliance monitoring, seismic and sound source verification, and long-term ecological monitoring.
  • Tidal Dynamics: Long-term tidal regime monitoring for system design and hazard prediction.
  • Data Transmission: Internal storage, telemetry, cellular, satellite, and seabed fiber network options for real-time or archival delivery.
Beyond field data acquisition, CSA will utilize those data and provide analysis and statistics that inform engineering and operational decisions:
  • Metocean Statistics: Development of site-specific wind, wave, current, and tidal climatologies, including seasonal variability, long-term trends, persistence, and occurrence statistics to characterize baseline environmental conditions.
  • Spectral & Directional Analysis: Analysis of wave energy distributions, directional characteristics, wave roses, scatter diagrams, and joint relationships between wave height, period, and direction to support operational and engineering assessments.
  • Environmental Modeling: Integration of metocean datasets, hindcasts, reanalysis products, and numerical modeling tools to reconstruct long-term environmental conditions and develop representative metocean databases.
  • Extreme Value Modeling: Application of advanced statistical methods to quantify extreme environmental conditions, return periods, exceedance probabilities, and rare-event scenarios, including Monte Carlo simulation and uncertainty analysis.
  • Integrated Environmental Analysis: Evaluation of interactions among waves, winds, currents, and tides through joint probability analyses, occurrence matrices, and environmental state characterization for design, operations, planning, and risk assessment.

Featured Project

Deep Ocean Metocean Monitoring, Clarion Clipperton Zone

Since 2019, CSA has designed, fabricated, and deployed subsurface metocean buoy arrays in water depths up to 6,000 m to support deep ocean mineral exploration in the Pacific. Instrumentation includes acoustic Doppler current profilers and sensors for currents, waves, temperature, conductivity, dissolved oxygen, suspended sediments, and pH — one of the deepest sustained metocean monitoring programs in the industry.
