船体部分 2.1 HULL CONSTRUCTION 船体结构 2.1.1 GENERAL 概述 The hull constructions are including the main hull, forecastle, poop deck, deck houses, engineer room, engine casing, funnel, appendages (such as bilge keel, bulwark). The vessel to be of steel and all welded constructions. 船体结构包括主船体，艏/艉楼，甲板室，机舱，机舱棚，烟囱，船体附件（如舭龙骨，舷墙）等。本船结构为钢质全焊接结构。 Hull construction’s materials & scantling designs are to be complied with the rules of Classification Society. Where there is not be mentioned in the rules of Classification Society, the designs shall be done according to the design standard and shipbuilding practices . The designs of construction shall follow the principle of continuous structures. 船体结构的材料及构件尺寸设计应满足船级社规范要求。船级社规范未作规定的构件，将根据设计标准和惯例确定。结构设计将遵循结构构件连续性的原则。 The arrangements of structural members to be arranged in considering for easy access and maintenance 结构构件布置应考虑便于通行的原则。 2.1.2 MATERIALS 材料 The materials of the steel plates and hull structural members are normal mild steel and shall comply with the rules of Classification Society if necessary,. 钢板和型材为船用普通的碳素钢，并应满足船级社规范的有关要求。 Casting steel shall comply with the rules of Classification Society if necessary . 铸件应满足船级社规范的有关要求。 2.1.3 WELDING 焊接 The welding conditions have to meet the requirements of class and Owners inspections. Welding shall be carried out under dry and clean conditions, weather protected as far as possible. 焊接条件需要满足船东和船级社的检验要求。焊接需要在干燥和清洁条件下进行，尽量进行露天保护。 Two side continuous welding will be used in tanks including fore peak, after peak, double bottom, wing tanks, holds, engine room as well as in all spaces exposed to weather and in wet spaces prone to corrosion (bathrooms, galley, pantries, laundries, drying rooms, etc). 所有舱必须用双面连续焊接包括艏尖舱，艉尖舱，双层底，边舱，货舱，机舱以及露天处所和易于被腐蚀的潮湿处所（浴室，厨房，餐具室，洗衣间，干衣室等） Single sided-, intermittent-, chain- or zigzag welding will be allowed, as far as permissible according to the classification society, where structural parts are not exposed to weather or moisture. 可采用单面焊，间断焊，并列焊或交错焊，根据船级社要求，结构件不要暴漏在露天或潮湿处。 The formation of notches and burn-in (undercut) during welding shall be avoided and to be given the necessary attention at design and production stage. 在焊接期间应该避免形成切口及咬边，在设计及生产阶段要特别注意这一块。 Welding at low environmental temperatures will be in accordance with class requirements. Welding consumables used are to be suitable for the parent metal to be welded and are to be approved by the classification society. Where filler materials having tensile properties deviating (downwards) from the parent metal are used, this fact must be taken into account when dimensioning the weld joints.
