In this article , the way of calculation , installation and problem handling , quoted of sulzer , the main engine maker , and classification societies like lloyd ' s , dnv and bv are referred 编写过程中，吸收了主机制造商苏尔寿及英国船级社劳氏、挪威dnv船级社、法国bv船级社关于主机和轴系校中计算及安装等问题处理的方法和技术。
Dnv , nk and bv , etc . in order to ensure the propellers of quality available , it is expected that the set of instruction would be helpful for surveyors to conduct the survey with proper , standard and unified procedure 希望形成一套以供指导中国船级社现场进行船用螺旋桨制造和修复检验的基本程序，使ccs的检验程序更加规范，检验质量更加提高。
Anefficient quality assurance system has been built up according to iso9001 , which is approved by dnv . all the products are developed , tested , manufactured and inspected in comply with solas , lsa , msc . 81 and other latest international regulations 公司建立了完善的质量保证体系，已通过挪威船级社dnv iso9001质量认证，产品严格按照solas lsa和msc . 81 70等最新的国际规范要求进行研制，试验生产和检验。
This article calculates the finite element modal using the different boundary condition of ccs , dnv , lr and gl , compares the calculation result with the permit stress to prove the safety of structure and then analyzes the results and comes to conclusion 在计算中，本文分别按照ccs 、 dnv 、 lr 、 gl的边界条件进行计算求解，将计算结果与ccs 、 dnv 、 lr 、 gl各自的强度标准进行比较，校核船舶结构强度是否满足要求。
Zhonghua shipyard signed with the owner the shipbuilding contract in 1995 and the first contract is total 4 vessels and then they signed total 16 vessels till november 1999 and the marine classification society is dnv for the first 10 vessels and bv for the subsequent 中华造船厂于1995年同船东签订造船合同，首合同为4艘船，直到1999年11月为止。此项目共与船东签约16艘船，此项目的前10条船为dnv船级社标准，其余的船为bv船级社标准。
Since then , preparations have proceeded over about 2 years including constructing an " environmental management system ( ems ) . " consequently , the hanno plant acquired iso 14001 certification after the preliminary and full review by the dnv ( certification institution ) , held in december 1998 and february 1999 respectively 其结果是分别于98年12月和99年2月通过dnv (认证机关)的预备审查和正式审查，因而饭能工厂取得了iso14001认证。
But in calculation , they have difference . this article main purpose is to analyze the different boundary condition how to affect the stress result . this article first elaborates the ship structure direct calculation concrete methods and regulations of ccs , dnv , lr and gl 但是，各船级社进行直接计算时所采用的具体方法有所不同，本文主要研究ccs 、 dnv 、 lr 、 gl四家船级社在进行船舶结构强度直接计算时，各自采用不同的边界条件处理方法，对计算结果的影响。
