22、 Intact stability of the craft is to be in accordance with the requirements of Part 3, Chapter 3 of the High-Speed Craft Rules. For Wind-SC(A) craft where the Administration has no specific subdivision and damage stability requirements, the craft is to comply with one of the following standard: i) T

23、he IMO High Speed Craft Code Chapter 2, regardless of tonnage, or ii) A published standard from an organization recognized by the ABS For Wind-SC(B) craft where the Administration has no specific subdivision and damage stability requirements, the craft is to comply with 3-3-1/3.3 of the High-Speed C

24、raft Rules. 3 Intact Stability for Craft Equipped with Cranes 3.1 Specific Applicability This section applies to each craft that: i) Is equipped for lifting of cargo or other objects; and ii) Has a maximum heeling moment due to hook load greater than or equal to: (0.67)()(GM)(F/B) meter-metric tons

25、(foot-long tons) where: = displacement of the craft with the hook load included, in metric (long) tons GM = metacentric height with hook load included, in meters (feet) F = freeboard to the deck edge amidships, in meters (feet) B = beam, in meters (feet) 3.3 Definitions i) Hook load is the weight of

26、 the object lifted by the crane. ii) Load radius is the distance illustrated in Section 2, Figure 1 iii) Crane Heeling Moment is the maximum heeling moment developed by multiplying the weight of the hook load and boom by the horizontal distance from the crafts centerline to the hook load and boom ce

27、nter of gravity, considering the full range of crane elevations and weights. The resulting heeling moment is to be converted to a heeling arm at zero degrees by dividing it by the craft displacement. The heeling arm is to be assumed constant for all heel angles. iv) Equilibrium heel angle is the ang

28、le of heel under the combined effects of the hook load, counter-ballasting and a beam wind.

34、FT .2013 5.1.2 Each craft is to comply with the following conditions: i) Either for each loading condition (see 2/5.1.1) and pre-lift condition, or the range of conditions, including pre-lift conditions, delineated by the lifting operations guidelines contained in the trim and stability booklet; and

35、 ii) Crane Heeling Moment, and iii) The effect of beam wind on the projected area of the craft (including deck cargo) should be evaluated for 25.7 m/s (50 knots) wind speed. Should a lesser wind speed be used, that wind speed shall be listed in the trim and stability booklet as an operational restri

36、ction during lifting operations. The wind heeling moment shall be calculated as: P A H N-m (kgf-m, lbf-ft) where P = wind pressure, calculated as per below A = projected lateral area, in square meters (square feet), of all exposed surfaces (including deck cargo), in the upright condition H = vertica

37、l distance, in meters (feet), from the center of A to the center of the underwater lateral area or approximately to the one-half draft point This wind heeling moment is to remain constant for all heel angles. P = f Vk2ChCsN/m2(kgf/m2, lbf/ft2) where f = 0.611 (0.0623, 0.00338) Vk= wind velocity in m
