大连理工大学专业学位硕士学位论文摘 大连理工大学专业学位硕士学位论文 摘 要 本文结合大连新船重工建造的惠州生活模块建造过程中模块整体上驳方案设计中 的关键结构和部位，利用有限元的理论进行了设计，并结合实际情况，对整个模块的上 驳方案进行了合理的设计和优化，保证了模块在建造完工后的安全顺利上驳运输到使用 地点，满足了实际生产的需要。 2003年，大连新船重工为了进一步开拓海洋工程市场，和美国CACT公司共同承 担了惠州生活模块的建造任务，由于海洋工程的日益繁荣，使大型浮吊的租用非常紧张， 需要用拖移方式解决模块的上驳交工问题。 作者借助主管本模块建造工艺技术的机会，利用大连新船重工现有的场地和设施情 况，设计了合理、安全、节省的模块拖移方案，其中，除了拖移的整体布置、拖移顺序 的设计、驳船的实际调载控制等方面的工作以外，重点在拖移的核心结构，过桥梁和滑 靴的结构设计和强度校核方面做了一些工作，使整个模块的拖移得到了技术基础的保 证。作者就是在此基础上，对于该方案的设计理论基础、模块的整体情况、大连新船重 工在该方面的实际情况、拖移过程的总布置、局部安全要求、保险检验的要求，设计中 的理论校核结果、实施过程中的施工要求等方面给予描述，为今后同样或相似的工程设 计和施工提供了经验和技术基础。 关键词：模块上驳拖移；过桥梁；滑靴；有限元 惠州模块拖移上驳方案盼设计Load．out 惠州模块拖移上驳方案盼设计 Load．out Procedure for HUIZHOU Module Abstract This article is for the 10ad．out WOrks of HUIZHOU module built in DALIAN NEW HEAVY INDUSTRY LIMITED CO．0PERATION(DNSl on 2004．The design works focuses on the main structure of link．beam and the skid—shoes based on the FEM theory．This load．out plan has the reasonable design and a very good promotion for the concrete condition of DNS．Based On this procedure the module 10ad．out work iS safety and smoothly．And nOW it iS much better serving in the oil．field． Since 2003．the offshore market is prosperity．DNS ally to CACT Company which is belong to USA have signed the fabrication contract about the HUIZHOU module．And the normal load．out method by floating crane iS much difficult because of the lack of floating cranes．So the towing method iS needed for this module’S fabrication． The Anther who is the chief designer for the module fabrication has designed the load．out plan for this module according to the facility and the quay in DNS．After the load．out work has been done．It iS proved that the procedure iS reasonablesafetyeconomization． Besides the generaIIayout and towing sequence and ballasting adjustment，the anther focuses on strength checking for the link．beamthe skid—shoes by FEM．Based on this，the anther describe the theory bases．general condition for this work，concrete condition in DNS，towing layout for these equipments，safe
