III. Purpose

    The Coast Guard is issuing this request for information (RFI) in 
response to Section 8431 of the William M. (Mac) Thornberry National 
Defense Authorization Act (NDAA) for Fiscal Year 2021, Public Law 116-
283. In that section, Congress required the Coast Guard, in 
coordination with the Federal Aviation Administration (FAA), to develop 
plans for a demonstration program that will determine whether a WIG 
craft, carrying at least one individual, is capable of the following:
    (1) Providing transportation in areas in which energy exploration, 
development, or production activity takes place on the Outer 
Continental Shelf; and
    (2) Safely reaching helidecks or platforms located on offshore 
energy facilities under the WIG craft's own power.
    Congress directed that Coast Guard and the FAA report on, among 
other things, any regulatory changes with regard to inspections or 
manning that would be necessary to allow for craft operation between 
onshore and offshore facilities, any regulatory changes with regard to 
airspace and other aircraft operations necessary to allow for safe 
operations on or near helidecks and platforms on offshore energy 
facilities, and any other statutory or regulatory changes related to 
FAA authority over craft operation.
    The Coast Guard will use the public comments received in response 
to this RFI as the first step in developing a WIG craft demonstration 
program, and to better understand the state of WIG craft development.

IV. Background--Wing-in-Ground (WIG) Craft

    As statutorily defined in 46 U.S.C. 2101(54), a WIG craft is ``a 
vessel that is capable of operating completely above the surface of the 
water on a dynamic air cushion created by aerodynamic lift, due to the 
ground effect between the vessel and the water's surface.'' As defined 
in 46 U.S.C. 2101(45), WIG craft that can carry one or more passengers 
for hire are ``small passenger vessels,'' and are regulated as such by 
the Coast Guard.
    A WIG craft relies on ground effect, an aerodynamic effect that 
creates an air cushion between the craft's wings and the surface. When 
a WIG craft is operating very close to the surface and under the 
influence of ground effect, there is a reduction in the upwash, 
downwash, and wingtip vortices generated by its wing that results in a 
condition of improved performance. As a result of the reduced wingtip 
vortices, there is a reduction in induced drag. Operating within ground 
effect significantly improves a craft's performance when its wing is at 
a height of about one-half its wingspan or less above the surface. 
Accordingly, a WIG craft cannot fly very far above the surface before 
it loses the advantage of ground effect. It may also not be able to 
maintain sustained flight at higher altitudes.
    When operating within ground effect, the reduced drag allows WIG 
craft to carry a payload with less propulsion energy than would be 
required by an aircraft operating out of ground effect. Operating 
within ground effect and not in contact with the surface also permits a 
WIG craft to operate at higher speeds than conventional watercraft. 
This makes WIG craft particularly attractive for passenger service on 
waterway routes.
    Because WIG craft can operate very close to the surface, and 
because waterways provide an effective operational route for WIG craft, 
Congress has made the legislative choice to designate WIG craft as 
vessels when operating in the maritime domain. Accordingly, the Coast 
Guard has statutory responsibility for the certification and regulation 
of WIG craft that operate on U.S. waters. This authority, however, is 
not exclusive, and does not restrict the ability of any other agency, 
such as the FAA, from regulating these craft when their operation falls 
within its statutory jurisdiction.

V. Request for Information

    The Coast Guard requests relevant comments and information from the 
public, and particularly from offshore facility operators, including 
gas and oil facility operators, wind farm operators, the WIG craft 
community (designers, manufacturers, and operators), and persons 
conducting operations in airspace that may be affected by the operation 
of WIG craft.

    When considering your comments and suggestions, we ask that you 
keep in mind the Coast Guard's mission to ensure a safe, secure, and 
resilient marine transportation system that facilitates commerce and 
protects national security interests. Commenters should feel free to 
answer as many questions as they would like, but also provide 
specificity, detail, and the logic behind any finding or numerical 
estimates.
    The following information is requested; please provide as much 
detail as possible:
    (1) From offshore facility operators:
    (a) What interest is there in participating in a WIG craft 
demonstration?
    (b) What are the potential advantages, drawbacks, and concerns, 
cost-related or otherwise, with respect to using WIG craft for 
transportation support?
    (c) What is the feasibility of a WIG craft to safely land and take 
off from a helideck (airborne mode), or to taxi up to an offshore 
platform (afloat mode)?
    (d) What modifications to offshore platforms would be required in 
order to enable such operations?
    (2) From the WIG craft community:
    (a) What is the current state of WIG craft development, both 
domestic and foreign?
    (b) What WIG craft are currently available, or will be available 
within 1 year, for an operational demonstration to an offshore 
platform?
    (c) What are the capabilities of existing WIG craft to reach 
helidecks or platforms located on offshore energy facilities, and how 
many existing WIG craft are operational for any route, or working 
prototypes under test and evaluation, or designs in progress?
    (d) What are the dimensions and operational characteristics of WIG 
craft; for example, speed, range, ground effect altitude, and passenger 
and cargo capacity?
    (e) What are the weather and other factors that might limit WIG 
craft operations on exposed offshore routes?
    (f) What are the costs and time estimates to manufacture WIG craft, 
and what resources are needed to manufacture them; for example, 
personnel, equipment, and raw material?
    (3) In general, from both offshore facility operators and the WIG 
craft communities:
    (a) What are the resources needed to plan and conduct a 
demonstration of offshore WIG craft operations?
    (b) What would be the milestones and timeframe to conduct such a 
demonstration?
    (4) Should current aircraft, airman, air carrier, and commercial 
operator requirements, as set forth in 49 U.S.C. and Title 14 of the 
Code of Federal Regulations apply to the certification and operation of 
WIG craft? (Note: 49 U.S.C. 40102(a)(6) defines an ``aircraft'' as 
``any contrivance invented, used, or designed to navigate, or fly in, 
the air.'') If current requirements should be revised, please indicate 
what changes would be considered necessary.
    (5) Are any additional regulatory, guidance, or policy changes 
needed to facilitate development of a domestic WIG industry? Where 
appropriate, please include why the changes are necessary.
    (6) What is the predicted growth and scope of the WIG craft 
technology in terms of its domestic deployment in industry?
    (7) Regarding credentialing:
    (a) Should WIG operators be required to hold a Merchant Mariner 
Credential with the appropriate route and tonnage limitations for the 
vessel?
    (b) Should current airman certification requirements apply to the 
operation of WIG craft? If current requirements should be revised, 
please indicate what changes would be considered necessary (e.g. 
category and class ratings, aeronautical knowledge, flight proficiency, 
aeronautical experience).
    (c) Should WIG credentials be one endorsement that covers both the 
maritime and aviation aspects, or should there be individual 
certificates or endorsements for each aspect?
    (d) Should aviation or maritime simulation training be required to 
obtain certification or an endorsement to conduct WIG operations?
    (f) Should aeronautical experience be credited toward any service 
requirements to qualify for a WIG endorsement?
    (g) If credit for aeronautical experience is to be given, what is 
the appropriate conversion of flight time to maritime service time?
    (8) Finally, the Coast Guard seeks public comments on WIG craft 
development and technology and their potential ability to operate on 
coastwise and offshore routes that may not be covered in the questions 
above.
