CSQS（中国造船质量标准）English version.doc

1NOTESThere documents are shipbuilding quality standard implemented by our yard presently. They consist of two parts like QUALITY CONTROL THROUGH PRODUCTION and CONSTRUCTION ACCURACY Taken as a main basis for the shipbuilding in our yard, this construction accuracy is made according to the shipbuilding quality standard in advanced shipbuilding nations, international conventions as well as rules and regulations of some well-known classification societies. For this purpose, we require:1. detailed workmanship and drawings, if no other specific restriction, comply with the respective requirements stated in this STANDARD. In case of difference, this STANDARD shall govern all.2. should there be some items in the newbuilding contract or technical specification of higher requirement than this STANDARD, these items should be regarded as an exception and performed according to specific requirement otherwise announced.CONTENTS PART 1 QUALITY CONTROL THROUGH PRODUCTION1 STEEL MATERIAL AND PROCESSING………………………………………61.1 Steel material…………………………………………………………………… ..61.2 Steel processing………………………………………………………… ………...62 FIXING AND ASSEMBLING……………………………………………………72.1 Fixing and assembling of parts and members………………………………….…72.2 Block assembling…………………………………………………………………73 WELDING……………………………………………………………………….83.1 Preparation before welding……………………………………………….………83.2 Welding process………………………………………………………………….83.3 Welding inspection……………………………………………………………….83.4 Key points of quality control……………………………………………………..94 TIGHTNESS TEST………………………………………………………………..95 FABRICATION,FIXING,TIGHTNESS TESTING AND FLUSHING OF PIPES………………………………………………………………………………105.1 Fabrication of pipes………………………………………………………..…….105.2 Fixing of pipes and fittings…………………………………………………… .115.3 Tightness testing of piping system……………………………………………....125.4 Flushing of pipes…………………………………………………………………126 PAINTING………………………………………………………………...………136.1 Pre-treatment of steel surface……………………………………………………136.2 Shop primertouch-up………………………………………………………….....136.3 Secondary derusting and surface cleaning…………………………………...….136.4 Painting work…………………………………………………………………..137 HULL OUTFITTING……………………………………………………………137.1 Pre-outfitting of ship equipment…………………………………………………137.2 Approval of ship equipment……………………………………………………...137.3 Installation of ship equipment……………………………………………………147.4 Key points of quality control…………………………………………………….148 MACHINERY INSTALLATION……………………………………………….158.1 Shafting and propeller…………………………………………………………..158.2 Main engine and accessories……………………………………………………178.3 Auxiliary machinery…………………………………………………………….188.4 Boiler……………………………………………………………………………199 ELECTRIC INSTALLATION………………………………………………….199.1 Electric fittings………………………………………………………………….199.2 Cable laying……………………………………………………………………..209.3 Installation and earthing of electric equipment…………………………………209.4 Connection and earthing of metal covering of cables…………………………..2110 AUTOMATIC CONTROL AND REMOTE CONTROL,TELEMETRY EQUIPMENT AND THEIR TESTING……………………………………….…2110.1 Sensors………………………………………………………………………...2110.2 Automatic control and remote control…………………………………….…..2210.3 Monitoring and alarming………………………………………………….…..2210.4 Test of unattended engine room…………………………………………….…2311 MOORING TEST AND SEA TRIAL………………………………………..2311.1 Mooring test and sea trial for hull part………………………………………..2311.2 Mooring test and sea trial for machinery part…………………………….…...2411.3 Mooring test and sea trial for electric part………………………………….…2512 COMPLETION AND DELIVERY…………………………………………..2512.1 Delivery of cabin equipment, spares and supplies……………………………2512.2 Inspection of marking and operation instructions……………………………...2512.3 As-built drawings and ship delivery documents………………………………2612.4 Certificates to be handed over…………………………………………………26PART 2 PLANS FOR APPROVAL AND INSPECITIONS AND TESTS FOR ACCEPTANCE1 PLANS FOR APPROVAL……………………………………………………..271.1 General ……………………………………………………………………….271.2 Plans and documents to be submitted for review and approval………………272 INSPECTIONS AND TESTS FOR ACCEPTANCE……………………..322.1 General……………………………………………………………………….322.2 Items of inspection and tests………………………………………………….33PART 3 CONSTRUCTION ACCURACY1 HULL CONSTRUCTION……………………………………………………341.1 Steel materials……………………………………………………………….341.2 Marking …………………………………………………………………….361.3 Cutting……………………………………………………………………….371.4 Forming……………………………………………………………………..391.5 Fixing and assembling………………………………………………………421.6 Welding……………………………………………………………………...491.7 Fairness and finishing……………………………………………………….511.8 Principal dimensions and deformation………………………………………561.9 Draught and freeboard marks………………………………………………..572HULL OUTFITTIN。
