摘 要
由于石油平臺支援船(OSV)的設(shè)計和建造難度和風(fēng)險較大,相比于先進(jìn)國家,其在我國的發(fā)展相對較慢。與國外相比,在支援船設(shè)計方面我國仍存在巨大差距,主要有:①沒有市場競爭力強(qiáng)的品牌船型;②技術(shù)儲備不足,產(chǎn)品未形成標(biāo)準(zhǔn)化與系列化;③船型積累不足,船舶航行性能預(yù)報和優(yōu)化設(shè)計技術(shù)落后;④開發(fā)設(shè)計手段比較落后,設(shè)計周期長,不能滿足數(shù)字化造船的需要。
在船舶設(shè)計中,人們越來越認(rèn)識到船體型線設(shè)計在船舶設(shè)計中的重要地位,因此,如何進(jìn)一步提高船體型線設(shè)計水平,進(jìn)而提高船舶性能,一直是船舶設(shè)計工作者的研究重點(diǎn),也是造船界不懈的追求。目前,表達(dá)船體形狀最常用的方法是圖示法,即用船體型線圖來描述船體的形狀特征。船體型線圖設(shè)計是船舶設(shè)計的重要方面,是結(jié)構(gòu)設(shè)計和總布置等其他各項(xiàng)設(shè)計的基礎(chǔ),也是保證船舶具有優(yōu)良性能的重要方面。型線設(shè)計是船舶總體設(shè)計的一項(xiàng)重要內(nèi)容。
本課題是大功率石油平臺供應(yīng)船型線設(shè)計,首先根據(jù)優(yōu)化鎮(zhèn)江船廠71m 石油平臺支援船得到新船的主尺度,在依據(jù)海洋供應(yīng)船的船型特點(diǎn),設(shè)計出優(yōu)良的石油平臺支援船船體型線。然后通過模型實(shí)驗(yàn)驗(yàn)證此型線的優(yōu)良性,最后通過船型變換,得到一組石油平臺支援船系列型線。
因此本論文的研究工作主要有:
1、分析船舶型線設(shè)計應(yīng)考慮的因素和型線設(shè)計方法,并結(jié)合海洋供應(yīng)船的船型特點(diǎn)和型線設(shè)計因素,設(shè)計出性能優(yōu)良的船型;
2、理論結(jié)合實(shí)際,通過海洋供應(yīng)船船模實(shí)驗(yàn)驗(yàn)證所設(shè)計的船舶型線的優(yōu)良性;
3、生成型線系列,通過以模型試驗(yàn)所驗(yàn)證的優(yōu)良的船舶型線為參考船,并經(jīng)過船型變換主尺度,得到此船的系列型線。

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.

Key word: Oil Supply Vessels; lines design; lines series; hull form transformation
