What Oceanweather does
Oceanweather Inc. (OWI) is a Stamford, Connecticut-based metocean consulting firm founded in 1977 by Dr. V. J. Cardone, Dr. J. A. Greenwood, and C. V. Greenwood. It serves the offshore oil and gas, coastal engineering, international shipping, and government research communities by producing long-term wind, wave, and ocean-current climatologies used for offshore structure design and certification, site operability assessment, hurricane and storm planning, and vessel routing. The firm is employee-owned under an ESOP since 2003 and is one of the smallest specialized players in the niche, with only 1–10 employees listed.
OWI's technical core is the proprietary OWI3G third-generation spectral wave model, developed and maintained entirely in-house; the firm states it is the only forecast center globally (public or private) running operational global and regional wave models developed in-house. The stack also includes the IOKA Interactive Objective Kinematic Analysis system for wind field reconstruction, tropical cyclone wind field modeling described as an industry gold standard, ADCIRC+SWAN coupling for shallow-water surge and wave simulation, and integration of ERA5 reanalysis with statistical corrections. Outputs include basin-wide hindcasts (GROW, GOMOS, NEXTRA, SEAFINE, WANE, NAMOS, PAMOS, CASMOS, BOMOS, PERGOS, TAMOMS), operational forecasts (CYCLOPS for tropical cyclones, VVOS for vessel routing), high-resolution coastal modeling, a Digital Data Services API, and towing-transport tools (TOWSIM).
Commercially, OWI runs four intertwined revenue streams: multi-year Joint Industry Projects (JIPs) that deliver basin-wide hindcasts to oil and gas and government anchor participants on a subscription-like basis; speculative hindcast products (GROW, GROW-FINE, Advanced Spec) licensed per point or per block; dedicated custom studies priced as professional services; and operational forecasting subscriptions plus API access. Distribution is primarily direct sales, supplemented by two named regional joint ventures (PERGOS with DHI for the Persian Gulf since 2005; MACH with BMT Argoss and the UK MetOffice for West Africa since 2015). Pricing is opaque and quote-based, and 28 consecutive years exhibiting at the Offshore Technology Conference (OTC) in Houston functions as the primary brand-building channel alongside an extensive peer-reviewed publication history.

Revenue model
- Joint Industry Projects (JIPs): Basin-wide studies where participants receive large archives of grid points with intensive wind analyses. Participants benefit from ongoing updates, verification against measurements, and input into future work. Higher upfront costs but ongoing relationship value.
- Speculative (Spec) Products: Pre-computed hindcasts sold on a per point or per block basis without requiring full JIP participation. Includes Advanced Spec, GROW-FINE, and GROW products. One-time or recurring license fees for data access.
- Dedicated/Custom Hindcast Studies: Site-specific proprietary studies designed around client application and needs. Custom deliverable outputs including wind fields, wave parameters, wave spectra, extremal analysis, and operational data.
- Operational Forecasting Services: Real-time wind and wave forecasting services including global and regional applications, tropical cyclone forecasting (CYCLOPS), high-resolution coastal modeling, vessel routing optimization (VVOS), and API data services.
Pricing tiers
| Model | Billing | Price |

Oceanweather competitors and assessment
Company assessmentDirect peers
- StormGeo: Norwegian-based provider of weather routing and operational forecasting for shipping, offshore, and renewables. Directly comparable to OWI's VVOS and CYCLOPS operational products for offshore and oceangoing customers.
- Met Office (UK): UK national meteorological service that also sells commercial marine and offshore forecasting services. Comparable to OWI on metocean modeling expertise and is a JV partner with OWI on the MACH West Africa hindcast.
- Weathernews Inc. Japan-headquartered global weather company with a strong marine routing and ship operations focus. Competes with OWI for vessel routing and voyage optimization customers in international shipping.
- BMT Group (BMT Argoss): UK-based marine engineering and consulting group whose BMT Argoss arm performs metocean hindcasting and forecasting for offshore and shipping. Directly comparable to OWI on basin-wide JIP hindcasts and is also a JV partner on MACH.
- DHI (Danish Hydraulic Institute): Independent water and marine environment consultancy that delivers metocean and coastal engineering studies globally. Direct peer to OWI in hindcast and modeling services, and OWI's JV partner on the PERGOS Persian Gulf product.
Others
- ECMWF (European Centre for Medium-Range Weather Forecasts): Public intergovernmental forecasting center that produces the ERA5 reanalysis which OWI itself uses as a forcing input. Not a commercial competitor, but its improving public reanalyses set a baseline that constrains OWI's pricing on entry-level products.
- NOAA (National Oceanic and Atmospheric Administration): U.S. federal agency providing free atmospheric and oceanographic data and wave models (including WaveWatch III) used by the same offshore and shipping customers OWI serves. Functions as an ecosystem and benchmark, not a direct commercial peer, but its data quality improvements affect OWI's competitive position.
Broad incumbents
- RPS Group (part of Tetra Tech): International environmental and marine consultancy, now part of Tetra Tech, with oceanographic, coastal, and offshore metocean capabilities. Competes with OWI in coastal and offshore engineering consulting, though metocean is one of many services.
- Fugro: Dutch global geo-data and offshore site characterization company that includes metocean measurement, hindcasting, and forecasting within a much broader offshore services portfolio. Overlaps with OWI on metocean deliverables to offshore E&P and renewables clients.
Emerging players
- Akselos: Swiss-based structural integrity platform that ingests metocean data to assess offshore asset safety. Adjacent to OWI in the offshore wind and O&G value chain, consuming rather than producing metocean data.
