【摘要】 由于石油平台支援船(OSV)的设计和建造难度和风险较大,相比于先进国家,其在我国的发展相对较慢。与国外相比,在支援船设计方面我国仍存在巨大差距,主要有:①没有市场竞争力强的品牌船型;②技术储备不足,产品未形成标准化与系列化;③船型积累不足,船舶航行性能预报和优化设计技术落后;④开发设计手段比较落后,设计周期长,不能满足数字化造船的需要。在船舶设计中,人们越来越认识到船体型线设计在船舶设计中的重要地位,因此,如何进一步提高船体型线设计水平,进而提高船舶性能,一直是船舶设计工作者的研究重点,也是造船界不懈的追求。目前,表达船体形状最常用的方法是图示法,即用船体型线图来描述船体的形状特征。船体型线图设计是船舶设计的重要方面,是结构设计和总布置等其他各项设计的基础,也是保证船舶具有优良性能的重要方面。型线设计是船舶总体设计的一项重要内容。本课题是大功率石油平台供应船型线设计,首先根据优化镇江船厂71m石油平台支援船得到新船的主尺度,在依据海洋供应船的船型特点,设计出优良的石油平台支援船船体型线。然后通过模型实验验证此型线的优良性,最后通过船型变换,得到一组石油平台支援船系列型线。因此本论文的研究工作主要有:1、分析船舶型线设计应考虑的因素和型线设计方法,并结合海洋供应船的船型特点和型线设计因素,设计出性能优良的船型;2、理论结合实际,通过海洋供应船船模实验验证所设计的船舶型线的优良性;3、生成型线系列,通过以模型试验所验证的优良的船舶型线为参考船,并经过船型变换主尺度,得到此船的系列型线。更多还原

【Abstract】 Owning to the difficulties and risks in the design and construction of Oil Supply Vessels (OSV), the development of such work is much slower in our country comparing with that in the advanced countries. And the gaps mainly focus on the following aspects:①lack of ship types with competitive edge for the brand in the market;②short of technical reserve, there is no serialization and standardization in the productions;③insufficient in the ship type accumulation, lagging behind in the prediction of the navigational performance and optimization design;④backwardness in the methods of development and design, and the design cycle is long which cannot satisfy the require of digital shipbuilding.People have woken up to the importance of the lines in the ship design. Therefore, it is a core research area for the designers, as well as the entire shipbuilding industry, to make a good line design, since it can improve the ship performance greatly. For the present, the most popular way to display the ship shape is graphic method, i.e. describing the shape feature of the ship with lines plan. The lines plan plays an important role in the ship design, which is the basis of the structure design and general arrangement, and which can also guarantee a good ship performance. Lines plan design is an important aspect in the overall design of the ships.This thesis is mainly concerning about the lines design of oil supply vessels with high power. Based on the principal dimensions of the new ship optimized from the No.71 OSV built by the Zhenjiang shipyard, the optimization procedure of the ship lines can be obtained according to the features of the ocean supply ships. The experiment is carried out to validate the design lines plan, and then, the lines series of OSV can be obtained through the transformation of the hull form based on the former work.The main efforts of this paper are focusing on:1) Investigating the relative factors and methods in the lines design, combined with the ship form features and design factors of ocean supply ships, to derive an optimized ship form.2) Validating the performance of the designed lines plan through the model test of ocean supply ships.3) Choosing the lines with good performance validated through the model test and using hull form transformation method to generate the lines series.更多还原
