1、6700吨杂货船建造技术说明书2 HULL PART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 constructions materials & scantling designs are to be complied with the rules of Classification Society. Where there is not be mentioned in the

2、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 c

3、omply 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 p

4、eak, 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

5、，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 t

6、he parent metal are used, this fact must be taken into account when dimensioning the weld joints. 在低温条件下的焊接应依照船级社的要求。焊接材料应适合于母材，并经过船级社的认证。 从母材部分开始使用具有伸缩性的填角材料之处，计算焊缝时应该考虑到这种情况。Welding procedure including edge preparation shall be executed in accordance with the Builder established modern welding procedure and practice with reference to Chinese shipbuilding standard and approved by the classification society.焊接程序包括边缘预处理，应该符合造船方参照中国造船标准制定的现代的焊接程序并且经船级社认证。Automatic welding shall be used to the grea

7、test extent. The welders engaged in the welding shall be fully qualified and holding welding certificates from the classification society for the type of welding carried out.自动焊应该被广泛的使用。从事的焊接的焊工应该有充分的资格和持有给焊接发证的船级社的证书。Electrodes and other welding materials have to be properly selected for the special intended purposes.焊条和其他形式的焊接材料应该有目的适当的进行挑选来用于特殊的焊接。All welding shall be continuous except in dry spaces in the superstructure and deckhouse where intermittent welding is permitted.除了上层建筑和甲板室的干燥空间焊接是

8、间断焊接，其他所有的焊接应该是连续焊接Care shall be taken to avoid stress concentration due to welding, heating and discontinuity of the structure or build-in stress.应该特别注意由于焊接，加热和结构的非连续性产生的应力集中和嵌入的应力。All foreign materials (water, rust, oil, sludge, dirt, paint etc.) that will affect the quality of the welding to be thorough removed before carry out welding.所有影响焊缝质量的杂质（如水，锈，油，油渣，灰尘，油漆等）须在焊接前全部予以清除。All damages to the steel material due to welding when block assemble or erection, shall to be rectified by welding and

9、 grind smooth, 由于烧焊对钢材产生的损坏，在分段合拢或吊装时，应使用焊接方式进行修正并打磨光滑。2.1.4 TESTING试验On strength decks and steel structures, hatch covers, etc. welding to be x-ray examined, complying with the requirements of the classification society and to Owners approval. Butt welding between major steel castings and structural members to be 100% x-rayed.依照船级社的要求和船东的认可，强力甲板和钢结构舱盖等等焊接需要用X射线检查。大的钢铸件和构件之间的焊接要100进行X射线检查。Additional x-ray tests above class requirements to be made as directed by Owners representative in case the result of x-ray found not satisfied-若船东对所作的X光线探伤不满意，除船级要求外，应该根据船东监理指导下再进行探伤。The areas and locations of x-ray to be mutually agreed between Owners representative and Builder and the Class during building period.X射线检查的位置和范围在建造期间需要船东监理和建造者和船级社相互协商决定。Radiographic inspections to be carried out to the satisfaction of Owners representative and class surveyors.射线检查的检查技术应当令船东监理和验船师
