Met-Ocean-Ice Data for Operational Decisions
• Met-Ocean-Ice
observation data is used
as inputs to making
operational decisions
related to:
– Proximate ice
“threats” that require
tactical activities to
mitigate risk (e.g.
iceberg towing)
– Severe conditions
that prevent
operational activities
(helicopter transport,
crane lifts,
oceanographic
deployments, etc.)
![Page 18: Industry use of Marine Environmental Prediction …godae-data/OP19/plenary/Theme6...Weather and ocean experts mitigating financial and safety risks for clients whose businesses are](https://reader035.fdocuments.in/reader035/viewer/2022071110/5fe5f9fb0038da5c213e9e89/html5/thumbnails/18.jpg)
Met-Ocean-Ice Data for Operational Decisions
• Observations (iceberg
positions) and model data
(current, wave and wind
models) are integrated in
iceberg drift models to
generate predictions of
future positions and risk
posed by icebergs
• Information is used to
identify threats and take
actions, e.g.:
– Tow iceberg
– Disconnect from well
– Move platform

Risk Dashboard R&D
• Risk Dashboard R&D project was
self-funded by Wood
• Goal was to create an easy-to-
interpret, at-a-glance view for
clients to identify their risk
• Risk system is comprised of:
– Risk Engine: sophisticated
statistical analysis and algorithms
to predict “probability” of
exceeding thresholds
– Risk Dashboard: Web-based
display that communicates an
at-a-glance view of potential risks
![Page 31: Industry use of Marine Environmental Prediction …godae-data/OP19/plenary/Theme6...Weather and ocean experts mitigating financial and safety risks for clients whose businesses are](https://reader035.fdocuments.in/reader035/viewer/2022071110/5fe5f9fb0038da5c213e9e89/html5/thumbnails/31.jpg)
Risk Dashboard R&D
• The risk determination starts with spatial mapping of the risk
• The risks are extracted from the risk map, at specific locations for the client
• The user can drill down in detail to further evaluate specific risks

• Trend toward open source development of
scientific models and software
• Increased access to global and regional
datasets and vast computing power
– benefits industries with a stake in the
oceans
• Lowered barriers for industry participation
and collaboration
– Feasible for private consultants to
develop local high-resolution flood
hazard/impact forecasting systems,
leveraging global/regional efforts by
academia government agencies
• Availability of in-situ oceanographic
datasets and atmospheric inputs still a key
challenge
• Example: Wood’s (Dr. Juan Gonzalez-
Lopez) ongoing engagement with
CARICOOS (Puerto Rico) to develop a
regional operational modelling system for
the Caribbean
