36、ons 1 Application The following definitions of symbols and terms are to be understood (in the absence of other specifications) where they appear in the Rules. 3 Length 3.1 Scantling Length (L) (2018) L is the distance in meters (feet) on the summer load line from the fore side of the stem to the cen

37、terline of the rudder stock. For use with the Rules, L is not to be less than 96% and need not be greater than 97% of the extreme length on the summer load line. The forward end of L is to coincide with the fore side of the stem on the waterline on which L is measured. 3.3 Freeboard Length (Lf) (201

38、8) Lfis the distance in meters (feet) on a waterline at 85% of the least molded depth measured from the top of the keel from the fore side of the stem to the centerline of the rudder stock or 96% of the length on that waterline, whichever is greater. Where the stem is a fair concave curve above the

39、waterline at 85% of the least molded depth and where the aftermost point of the stem is above the waterline, the forward end of the length, Lf, is to be taken at the aftermost point of the stem above that waterline. See 3-1-1/Figure 1. In ships designed with a raked keel, the waterline on which this

40、 length is measured is to be parallel to the designed waterline. FIGURE 1 0.85DDLfFBD DeckF.P.5 Breadth (B) B is the greatest molded breadth in meters (feet). ABSRULES FOR BUILDING AND CLASSING STEEL VESSELS .2018 3 Part 3 Hull Construction and Equipment Chapter 1 General Section 1 Definitions 3-1-1

41、 7 Depth 7.1 Molded Depth (D) (1997) D is the molded depth at side in meters (feet) measured at the middle of L from the molded base line to the top of the freeboard-deck beams. In vessels having rounded gunwales, D is to be measured to the point of intersection of the molded lines of the deck and s

42、ide shell plating. In cases where watertight bulkheads extend to a deck above the freeboard deck and are to be recorded in the Record as effective to that deck, D is to be measured to the bulkhead deck. 7.3 Scantling Depth (Ds) (1997) The depth Dsfor use with scantling requirements is the distance i

43、n meters (feet) from the molded base line to the strength deck as defined in 3-1-1/13.5. 9 Draft (d) d is the molded draft, and is the distance in meters (feet) from the molded base line to the summer load line. 11 Molded Displacement and Block Coefficient (1997) 11.1 Molded Displacement () is the m

44、olded displacement of the vessel in metric tons (long tons), excluding appendages, taken at the summer load line. 11.3 Block Coefficient (Cb) Cbis the block coefficient obtained from the following equation: Cb= /1.025LBwl d (SI & MKS units) Cb= 35/LBwl d (US units) where = molded displacement, as de

45、fined in 3-1-1/11.1. L = scantling length, as defined in 3-1-1/3.1 d = draft, as defined in 3-1-1/9 Bwl= the greatest molded breadth at summer load line 13 Decks 13.1 Freeboard Deck (2018) The freeboard deck is normally the uppermost complete deck exposed to weather and sea, which has permanent mean

46、s of closing all openings in the weather part thereof, and below which all openings in the sides of the ship are fitted with permanent means of watertight closing. Where a vessel is designed for a special draft, considerably less than that corresponding to the least freeboard obtainable under the In

47、ternational Load Line Regulations, the freeboard deck, for the purpose of the Rules, may be taken as the actual lowest deck from which the draft can be obtained under those regulations. 13.3 Bulkhead Deck The bulkhead deck is the highest deck to which the watertight bulkheads extend and are made eff

48、ective. 4 ABSRULES FOR BUILDING AND CLASSING STEEL VESSELS .2018 Part 3 Hull Construction and Equipment Chapter 1 General Section 1 Definitions 3-1-1 13.5 Strength Deck The strength deck is the deck that forms the top of the effective hull girder at any part of its length. See 3-2-1/11.1. 13.7 Super

49、structure Deck A superstructure deck is a deck above the freeboard deck to which the side shell plating extends. Except where otherwise specified, the term “superstructure deck” where used in the Rules refers to the first such deck above the freeboard deck. 15 Deadweight (DWT) and Lightship Weight (2018) For the purpose of these Rules, deadweight, DWT, is the difference in metric tons (long tons) between the displacement of the vessel at its summer load line in water having a specific gravity of 1.025 and the lightship weight. For the purpose of these Rules, lightship weigh
