14、 carriersPart 5C, Chapter 2(L 5 B / D 2.5 CB 0.6 1.1.4 The Rule requirements apply to welded hull structures made of steel having characteristics complying with requirements in Ch 3, Sec 1. The requirements apply also to welded steel ships in which parts of the hull, such as superstructures or small

15、 hatch covers, are built in material other than steel, complying with requirements in Ch 3, Sec 1. 1.1.5 Ships whose hull materials are different than those given in 1.1.4 and ships with novel features or unusual hull design are to be individually considered by the Society, on the basis of the princ

16、iples and criteria adopted in the present Rules. 1.1.6 The scantling draught considered when applying the present Rules is to be not less than that corresponding to the assigned freeboard. Chapter 1, Section 1 Common Structural Rules for Bulk Carriers Page 4 2012 1.1.7 Where scantlings are obtained

17、from direct calculation procedures which are different from those specified in Ch 7, adequate supporting documentation is to be submitted to the Society, as detailed in Sec 2. 1.2 Limits of application to lifting appliances 1.2.1 The fixed parts of lifting appliances, considered as an integral part

18、of the hull, are the structures permanently connected by welding to the ships hull (for instance crane pedestals, masts, king posts, derrick heel seatings, etc., excluding cranes, derrick booms, ropes, rigging accessories, and, generally, any dismountable parts), only for that part directly interact

19、ing with the hull structure. The shrouds of masts embedded in the ships structure are considered as fixed parts. 1.2.2 The fixed parts of lifting appliances and their connections to the ships structure may be covered by the Societys Rules for lifting appliances, and / or by the certification (especi

20、ally the issuance of the Cargo Gear Register) of lifting appliances when required. 1.2.3 The design of the structure supporting fixed lifting appliances and the structure that might be called to support a mobile appliance should be designed taking into account the additional loads that will be impos

21、ed on them by the operation of the appliance as declared by the shipbuilder or its sub-contractors. 1.3 Limits of application to welding procedures 1.3.1 The requirements of the present Rules apply also for the preparation, execution and inspection of welded connections in hull structures. They are

22、to be complemented by the general requirements relevant to fabrication by welding and qualification of welding procedures given by the Society when deemed appropriate by the Society. 2. Rule application 2.1 Ship parts 2.1.1 General For the purpose of application of the present Rules, the ship is con

23、sidered as divided into the following three parts: fore part central part aft part. 2.1.2 Fore part The fore part includes the structures located forward of the collision bulkhead, i.e.: Common Structural Rules for Bulk Carriers Chapter 1, Section 1 2012 Page 5 the fore peak structures the stem. In

24、addition, it includes: the reinforcements of the flat bottom forward area the reinforcements of the bow flare area. 2.1.3 Central part The central part includes the structures located between the collision bulkhead and the after peak bulkhead. Where the flat bottom forward area or the bow flare area

25、 extend aft of the collision bulkhead, they are considered as belonging to the fore part. 2.1.4 Aft part The aft part includes the structures located aft of the after peak bulkhead. 2.2 Rules applicable to various ship parts 2.2.1 The various chapters and sections are to be applied for the scantling

30、 carry dry bulk cargoes of cargo density 1.0 t/m3and above with specified holds empty at maximum draught in addition to BC-B conditions. b) BC-B: for bulk carriers designed to carry dry bulk cargoes of cargo density of 1.0 t/m3and above with all cargo holds loaded in addition to BC-C conditions. c)

31、BC-C: for bulk carriers designed to carry dry bulk cargoes of cargo density less than 1.0 t/m3. 3.1.3 The following additional service features are to be provided giving further detailed description of limitations to be observed during operation as a consequence of the design loading condition appli

32、ed during the design in the following cases: maximum cargo density (in t/m3) for additional service features BC-A and BC-B if the maximum cargo density is less than 3.0 t/m3(see also Ch 4, Sec 7, 2.1). no MP for all additional service features when the ship has not been designed for loading and unlo

33、ading in multiple ports in accordance with the conditions specified in Ch 4, Sec 7, 3.3. allowed combination of specified empty holds for additional service feature BC-A (see also Ch 4, Sec 7, 2.1). 3.2 Additional class notation GRAB X 3.2.1 Application The additional class notation GRAB X is mandat

34、ory for ships having one of the additional service features BC-A or BC-B, according to 3.1.2. For these ships the requirements for the GRAB X notation given in Ch 12, Sec 1 are to be complied with for an unladen grab weight X equal to or greater than 20 tons. For all other ships the additional class

35、 notation GRAB X is voluntary. 3.3 Class notation CSR 3.3.1 Application In addition to the class notations granted by the assigning Society and to the service features and additional class notations defined hereabove, ships fully complying with the present Rules will be assigned the notation CSR.
