CHAPTER 1 GENERAL


101. Application

This Guidance is to apply to the Wing-In-Ground Ships (hereafter referred to as "WIG Ships"), and constructed in steel, alloy aluminum or complex materials for hull construction and other structural members.


102. Equivalence


1. Hull structures, equipment, arrangements or scantlings which are not appropriate to apply the re- quirements of this Guidance or not specified in this Guidance, may be accepted by the Society provided that the Society is satisfied that such hull structures, equipment, arrangements or scantlings are equivalent to those complying with the requirements of this Guidance.


2. In spite of the other requirements in this Guidance, "Annex 3. Guidance on review/approval of risk- based ship design" may be applied, where it is considered by the Society that it is not practi- cable or not applicable to apply this Guidance. The Korean Industrial Standards(KS), recognized in- ternational standards or other standards considered equivalent by the Society may be applied instead of the requirements of this Guidance where it is acceptable by the Society.


103. Definitions

The definitions of terms used in this Guidance are as followings:

1. "WIG ship" is a ship which flies near above the water surface by using air cushion effect of high pressure generated by aerodynamical interaction between water surface and wing or hull (hereafter referred to as "ground effect"), without contact with the water surface.


2. "Length(L)" means the overall length of the underwater watertight envelope of the rigid hull, ex- cluding appendages, at or below the design waterline in the displacement mode with no lift or pro- pulsion machinery active.


3. "Breadth(B)" means the width of the broadest part of the moulded watertight envelope, excluding appendages, at or below the design waterline in the displacement mode with no lift or propulsion machinery active.


4. "Design waterline" means the waterline corresponding to the maximum operational weight of the ship with no lift or propulsion machinery active.


5. "Flap" means an element formed as integrated part of, or an extension of, a wing, used to adjust the hydrodynamic or aerodynamic lift of the wing.


6. "Lightweight" is the displacement of the ship in tonnes without cargo, fuel, lubricating oil, ballast water and fresh water in tanks, consumable stores, passengers and crew and their effects.


7. "shoulder station" is an area where passengers can be gathered in the event of an emergency and prepared to abandon the ship, if necessary.


8. "Operating station" means a confined area of the operating compartment equipped with necessary means for navigation, maneuvering and communication, and from where the functions of navigating, maneuvering, communication, commanding, conning and lookout are carried out.


9. "Passenger" is every person other than:

(1) the pilot or other person employed or engaged in any capacity on board a ship on the business of that ship

(2) a child under one year of age

(3) person temporarily on board

10. "Passenger WIG ship" is a WIG ship which carries passengers.


11. "General WIG ship" is a noncommercial WIG ship which does not carry passengers or ship which carries cargoes.


12. "Maximum take-off weight" means the weight up to which the WIG ship can take-off

over load of propulsion machinery at the condition of lightweight plus fuel, passenger and cargo weight.


13. "Small WIG ship" is a WIG ship of which the maximum person on board is not more than 12 person or the maximum take-off weight is not more than 5,670 kg.


14. "Extent of ground effect" is the altitude up to 100 % of mean aerodynamic chord length of WIG ship from mean sea level.


104. Type of WIG ship

WIG ship of type A is a ship which is certified for operation only in ground effect, WIG ship of type B is a ship which is certified to temporarily increase its altitude to a limited height outside the influence of ground effect but not exceeding 150 m, the minimum safe altitude of airplane specified by the International Civil Aviation Organization, above the surface. image
