Floating Wind Mooring Line Patents: Leaders & White Space 2026
A data-backed look at floating offshore wind platform mooring line patents: who is filing, which technical routes dominate, and where claim space is still open.
Filing growth = 2021 (1 records) → 2024 (3); 2024 is the last year we treat as complete.
What this landscape covers
Mooring line patents for floating offshore wind platforms sit at the intersection of marine engineering and wind turbine deployment. This landscape covers 18 published records filed or published between 2015 and the 2026 data cut-off, filtered to titles and claims naming floating offshore wind platforms together with mooring lines, cables or tendons, and classified under ship/marine vessel, hydraulic engineering, or marine propulsion codes. The scope is narrow by design: it isolates the mooring hardware and deployment claims rather than the broader floating wind platform literature.
Because publication lags filing by roughly 18 months, the most recent one to two years in any trend understate real filing activity. Family counts, not raw document counts, drive the assignee ranking below, which neutralises repeat filings across jurisdictions for the same invention.
Filing trend and technology mix
Two views of the same 18-record dataset: how filing has moved year over year, and which IPC subclasses the records fall into.
Filing trend, 2017–2026
Filings were flat at zero through 2017 before building slowly; the peak year so far is 2022 at 4 records. The tracked growth span, 2021 (1 record) to 2024 (3 records), works out to +200% and is the last span the dataset treats as complete, since 2025 and 2026 are still filling in behind the publication lag.
Publication lags filing by roughly 18 months, so 2025 onwards are still filling in. Growth rates on this page therefore end at 2024; running them to the last bar would understate the field.
Technology composition by IPC subclass
All 18 records carry a B63B ship/marine vessel classification, the anchor code for this scope. A third also carry F03D (wind motors), 22.2% carry E02B (hydraulic and waterway engineering), and single-digit shares appear in B63H (marine propulsion) and B66C (cranes and hoists). Because records can carry multiple classes, these shares add up to more than 100% of the 18 records and should be read as overlap, not as a partition.
Shares are the percentage of the 18 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Floating intervention platform for docking on an offshore wind turbine platform
The filing describes an intervention platform with a floating base and a wind turbine equipment lifting tower, fitted with a heave plate that protrudes laterally from the base and engages the lower surface of the offshore wind turbine platform. A ballast controller manages ballast volume in the floating base, allowing the platform to adjust trim and engagement force as it docks against the turbine structure.Filed by Technip Energies France, published 2023-10-04.

Citation counts inside this corpus favour older filings and should be read as a signal of influence, not of current commercial relevance.
Patent titles are shown in the language they were filed in, not translated, so that each record stays verifiable against the original filing — a translated title will not match in Eureka or in any national register. Publication numbers are shown where the record carries one (8 of 8 rows); clicking a row searches Eureka by that number.

Four read-outs from the same 18-record dataset, framed for someone deciding where to file next or who to watch.
The ranked field has no dominant holder
The leading assignee holds 5 records among the 9 ranked companies, and the fifth-placed company holds 2. That is a shallow ranking, not a blocking position, and it leaves room for a new entrant to build a comparable portfolio quickly.
Filing accelerated into 2022 and held
Filings rose from 1 record in 2021 to 3 in 2024, a +200% increase across that span, with the single peak year so far at 4 records in 2022. Because 2025 and 2026 are still filling in behind the publication lag, this should not be read as a plateau.
Most claims are written as marine hardware first
Every one of the 18 records sits in the B63B marine vessel class, but only a third also carry the F03D wind turbine class. That split suggests mooring line claims are more often drafted around hull, buoy or tendon mechanics than around turbine-specific load cases.
Europe leads receiving offices, China and the US close behind
The EPO receives the most filings in this scope at 5, ahead of China at 4 and the United States and WIPO PCT route each at 3. Australia and Germany each show single-digit counts, indicating the competitive filing activity is still concentrated in a handful of offices rather than spread globally.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to floating offshore wind platform mooring line patent landscape, with the prior art for and against each one.
Where to take this analysis
The dataset points to a field with room to move but a small number of citation anchors worth checking before drafting new claims.
Map claim scope against the most-cited records
The two most-cited records in this scope, both self-installing floating foundation filings, carry citation counts well above the rest of the field. Any new mooring line filing in this space should be checked against their claim scope before drafting.
Explore citation mapping in EurekaWatch the F03D overlap for turbine-specific claims
Only a third of records combine marine vessel and wind turbine classifications. A filing that ties mooring line behaviour directly to turbine load cases, rather than to hull or buoy mechanics alone, sits in a thinner part of the claim space.
Run a white space search in EurekaTrack the shallow assignee ranking
With the leading assignee at 5 records and the ranking dropping to 2 by fifth place, no single company has locked up this space. Monitoring new entrants each filing year is more informative here than tracking an incumbent.

This landscape identifies 18 published records worldwide that combine floating offshore wind platform terminology with mooring line, cable or tendon claims, filtered to marine vessel, hydraulic engineering and marine propulsion IPC codes. That is a narrow, purpose-built count, not a count of every floating wind patent, so a broader search on floating wind platforms generally will return a much larger number. Because publication lags filing by roughly 18 months, the true count for 2025 and 2026 filings will rise as those applications publish.
The assignee ranking covers 9 companies, with the leading company holding 5 records and the company in fifth place holding 2. That is a shallow spread rather than a dominant-leader pattern, and it includes a mix of energy engineering firms, wind turbine technology developers, and Chinese research institutes and universities. No single company's portfolio is large enough in this scope to be described as controlling the field.
Yes, on the evidence available: filings rose from 1 record in 2021 to 3 in 2024, a +200% increase across that span, with a peak year so far of 4 records in 2022. That growth figure stops at 2024 deliberately, since 2025 and 2026 filings are still working through the roughly 18-month publication lag and will understate real activity for now. Treat any apparent slowdown in the most recent one to two years as a reporting artefact rather than a real trend.
The European Patent Office leads this scope with 5 filings, followed by China at 4, and the United States and the WIPO PCT route each at 3. Australia and Germany each show smaller counts. This spread suggests applicants are pursuing multi-jurisdiction protection through Europe and the PCT route rather than concentrating filings in a single national office.
All 18 records in this scope carry a B63B ship and marine vessel classification, which anchors the dataset. A third of records also carry the F03D wind motor classification, 22.2% carry E02B hydraulic and waterway engineering, and smaller shares touch marine propulsion and crane or hoist classifications. Because a single record can carry more than one classification, these shares add up to over 100% of the 18 records and describe overlap between fields rather than a strict breakdown.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
