See Section 8 for specific requirements for the life-saving arrangements. 4 ABSGUIDE FOR BUILDING AND CLASSING WIND FARM SUPPORT CRAFT .2013 Section 2: Stability SECTION 2 Stability 1 Stability
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

39、bility ABSGUIDE FOR BUILDING AND CLASSING WIND FARM SUPPORT CRAFT .2013 7 5.1.3 Each craft is to have a righting arm curve with the following characteristics: i) The area under the righting arm curve from the equilibrium heel angle (based upon the wind heeling moment) up to the smallest of the follo
40、wing angles must be at least 0.080 meter-radians (15 foot-degrees): a) The second intercept b) The downflooding angle c) 40 degrees ii) The lowest portion of the weather deck and downflooding point should not be submerged at the equilibrium heel angle. iii) The heeling angle based on the crane heeli
41、ng moment and effect of the beam wind shall not exceed the maximum heel angle from the crane manufacturer. The righting arm curve is to be corrected for the increase in the vertical center of gravity due to the lifting operation. (The increase in the vertical center of gravity is due to the boom bei
42、ng in the elevated position, and the hook load acting at the elevated end of the boom). 5.3 Additional Intact Stability Standards Counter-ballasted Craft Craft carrying out lifts using counter-ballasting are to be reviewed to a recognized standard acceptable to ABS. 7 Other Features Operations such
43、as towing and firefighting impose heeling moments that affect the stability of the craft.
