1100. General
1101. Application
1. This Rules applies to survey and construction of floating docks which intend to be registered or which registered with classification.
2. The Rules are made for on the conditions that floating docks will be properly loaded and handled in sheltered waters; they do not provide for special distributions or concentrations of loading. The Society may also require additional strengthening to be fitted in any floating dock which in their opinion, may be subjected to severe stresses due to particular features in her design or when it is desired to make provision for exceptional loaded or ballasted conditions. In these cases particulars and relevant data are to be submitted for consideration.
3. The relevant parts of the Rules for Classification of Steel Ships (hereinafter referred to as「the Rules」) apply to essential constructions, machinery and equipment not specified in these Rules, as
may be required.
1102. Equivalency
Alternative hull construction equipment, arrangement and scantling will be accepted by the Society, provided that the Society is satisfied that such construction, equipment, arrangement and scantlings are equivalent to those required Rules.
1103. Other regulations
These Rules specify the requirements for the Classification of floating docks. Therefore, the atten- tion of owners, builders, and designers is directed to the regulations of national or local govern- ments, or other organizations which may contain safety, health, or other standards applicable to the floating dock.
1104. Towage certificate
Where the Society's towage certificate is requested by a builder/owner to enable a dock to be tow- ed at sea special consideration may be required to be given to the strength, freeboard and stability, and other items as considered necessary.
1105. Cranes
When the assignment of safe working load of cranes is requested by the builders or the owners, the Society will assign the safe working load in accordance with Pt 9, Ch 2 of the Rules for the Classification of Steel Ships.
1200. Classification Registry 1201. Character of classification

1300. Definition
1301. Length
The length (Ã ) is the distance, in meters, measured on water line when supporting a ship whose displacement is the lifting capacity between the aft end and the fore end of the bulkheads of the floating structures of the dock.
1302. Breadth
The breadth (Æ ) is the moulded breadth in meters measured at the greatest horizontal distance be- tween the inner surfaces of the outer side plating of wing walls.
1303. Depth
The Depth (Á) is the vertical distance in meters measured at the centerline from the inner surface of the bottom plating to the inner surface of the top deck plating.
1304. Safety deck
The safety deck is a watertight deck extending over the length of the wing walls and located be- low the top deck.
1305. Top deck
The top deck is the deck extending over the length of the wing walls to form the top of the wing walls.
1306. Pontoon
The pontoon is the structure that extends between and under the wing walls to form the bottom of the dock.
1307. Rest ballast water
The rest ballast water is ballast water which can not be discharged by pumps from ballast compartments.
1308. Compensating ballast water
The compensating ballast water is ballast water for reduction of stresses and deflections in the dock structures and for adjustment of the trim and heel of the dock.
1309. Lifting capacity
The lifting capacity (Ç) is the displacement of the heaviest ship it is intended that the dock shall lift in normal service.
1310. Light displacement
The light displacement of the dock is its complete weight including all machinery, cranes, equip- ment, full supply of consumables for operation of the dock (fuel oil, fresh water etc.), compensat- ing ballast water (if necessary) and rest ballast water.
