Metocean expertise × AI-augmented workflow — accelerating multi-scenario analysis for early-stage decisions

What We Do

Our core service is the Level 1 Metocean Desktop Study. Depending on your project scope, we deliver structured analysis across the following areas:

Service 01

Single-Site Climatology

Integrating multi-year reanalysis with local observations to characterize wind, wave, and typhoon climatology for a specific site or coordinate, with operability assessment for marine activities.

Service 02

Multi-Site Comparison & Screening

Cross-site benchmarking across multiple candidates, structured as a trade-off matrix across wind energy, wave, currents, operability, and typhoon exposure — for early-stage site selection.

Service 03

Operability Analysis for Specific Operations

Weather downtime estimation tailored to your vessel, equipment, operational thresholds (Hs, wind, period, gust), and project schedule — informing planning buffers and contingency.

How We Work

STEP 01

Scope Definition

Aligning on site coordinates, analysis period, intended use, and decision stage with the client; defining concrete deliverables.

STEP 02

Data Acquisition + QA

AI-augmented retrieval from authoritative international and local sources, with download, format normalization, initial QA, and validation against in-situ data — getting the workflow into interpretable form faster.

STEP 03

Analysis + Cross-Validation

Site-specific time series extraction, statistics, and visualization; cross-validation against alternative sources for seasonal patterns and magnitude.

STEP 04

Report Delivery

Chinese or English report, with full reproducibility manifest (data DOIs, versions, analysis parameters).

Public Data Sources

  • ERA5 — global atmospheric reanalysis (ECMWF)
  • Copernicus Marine WAVERYS — global wave reanalysis
  • IBTrACS — International Best Track Archive for Climate Stewardship, tropical cyclones (NOAA)
  • Taiwan Central Weather Administration (CWA) OpenData — coastal climate data and buoy observations

Additional sources (NEWA, CMEMS GLORYS, HYCOM, ASCAT, etc.) can be integrated based on project needs.

Our Quality Commitments

  • Full reproducibility — Every report ships with a complete parameter record (data DOIs, versions, analysis parameters, software versions), allowing you or a third-party reviewer to independently reproduce the results.
  • Honest uncertainty disclosure — Explicit statements on data biases, coverage gaps, and applicable scope.
  • Strict licensing discipline — All references are fully attributed, with commercial-use scope clearly noted.

Faster early-stage assessments, without compromising metocean depth

AI accelerates execution; metocean engineering judgment drives method and interpretation. Together, they enable more efficient comparison of sites, seasons, and operational conditions in the early decision stage.

AI-Augmented Workflow Accelerates Execution

From data acquisition and normalization, through QA, analysis, plotting, to draft reporting, our AI-augmented workflow accelerates the repetitive execution work. What traditionally takes weeks to months for early-stage metocean studies, we can compress into a shorter delivery window, enabling more efficient comparison across sites, seasons, and operational conditions.

Metocean Engineering Background Drives Judgment

Every report is human-reviewed before delivery: we verify data sources, confirm method appropriateness, ensure conclusions stay within what the data supports, and clearly state limitations. AI speeds up execution; expert judgment determines whether the analysis is truly fit for purpose.

Sample Cases

Below are public methodology demonstrations, illustrating the depth, framing, and limitations discipline of our early-stage desktop studies.The methodology and report structure are intended as reference; specific numerical values are illustrative and not the basis for client project design.

CASE 1

Changhua Offshore Climatology Study

5-year hourly + 20-year monthly climatology for a representative point off the Changhua coast.Key finding: strongest sea states during the 2019–2023 period were driven by the northeast monsoon, not direct typhoon passages

CASE 2

Taiwan Strait Site Screening Study

Cross-site comparison of three sites along Taiwan's offshore wind development corridor.Key finding: no single site dominates across all metrics — wind energy, wave, operability, and typhoon exposure form a structured three-way trade-off; the mid-strait location shows distinct channel-effect signatures.

FAQ

What role does AI play in your analysis workflow?+
AI is involved throughout the analysis workflow — supporting data preparation, plotting, draft generation, repetitive checks, as well as analysis and initial interpretation. Our metocean engineering team fully reviews each report before delivery, verifying method choices, interpretation, limitations, and final conclusions against professional standards. AI drives execution and analysis; people drive final review and quality assurance.
What kinds of projects are you suited for?+
Our services cover the full range of early-stage metocean studies: single-site climatology, multi-site comparison and screening, project-specific operability analysis, and more. Applications span offshore wind, coastal engineering (including port and harbor facilities), aquaculture and fisheries, as well as site investigation and commissioned research for academic or research institutions. Data sources include publicly licensed global reanalysis (ERA5), CWA Central Weather Administration data, and wave numerical model products. If your needs touch any of these areas, we can deliver fast, structured analysis. Not sure if you fit? Reach out — happy to discuss.
What's your edge versus a traditional consultancy doing early-stage metocean work?+
Primarily, what  AI tools bring to execution and analysis. In traditional consulting workflows, significant time is spent on data acquisition, normalization, QA, plotting, and drafting — repetitive work. PF Tech runs these steps through an AI-augmented workflow, freeing the engineering team to focus on method selection, multi-source integration, interpretation, limitations framing, and quality reviewWithin the same engagement, you receive deeper and more systematic analysis.
How does publicly available data differ from your delivered reports?+
Public datasets are raw material. Turning them into actionable site reports requires data integration, spatial interpolation, QA, cross-validation against local observations (e.g., CWA open data or proprietary in-situ records), and explicit annotation of limitations and uncertainties. Clients receive a site-specific analysis ready for direct decision-making — without having to handle raw files, interpret formats, or judge what the data can or cannot support.
Where can I use this report in my decision flow? What else might I need afterwards?+
Our reports serve the feasibility assessment and site screening stage, providing the foundation for scope definition, candidate site shortlisting, and risk identification. If your next step is detailed engineering design, investment decisions, or formal in-situ measurement, you'll typically also need in-situ data, long-term observations, and formal Extreme Value Analysis (EVA). We can help plan the in-situ campaign layout and timeline so your early-stage study connects smoothly to the next phase.
What are the typical timeline and budget?+
Timeline and budget vary with project scope, number of sites, depth of analysis, and complexity of integrated data sources — and are assessed per project. Get in touch with your requirements; we'll respond with quotation and timeline within a few business days.
We already have in-situ measurement data. How can PF Tech add value?+
Typical directions include:
  • Cross-validation and bias analysis between in-situ records and reanalysis data
  • Long-term extension of in-situ records (using reanalysis to fill in the temporal coverage beyond the measurement period)
  • Methodology audit and quality assessment of existing in-situ data
  • Integrated reporting combining in-situ and reanalysis sources
Can reports be modified after delivery? Is there ongoing support?+
Before finalization, we engage in reasonable back-and-forth discussion and revision with the client.Once a report is finalized and delivered, new requirements (e.g., new sites, new time periods, new analytical angles) are scoped and quoted as a separate engagement. All deliverables include a complete data source manifest, enabling easy reference or verification on your end.
Who are your typical clients?+
Common client types include offshore wind developers, marine engineering consultancies, port and coastal infrastructure planners, aquaculture and fisheries operators, and academic or research institutions
