4、造價和性能的船舶主要參數(shù)的確定。因此，基本設(shè)計包括船舶主尺度、船體線型、動力（數(shù)量和種類）的選取，以及船體、機械設(shè)備和主要結(jié)構(gòu)的布置。恰當(dāng)?shù)倪x取可保證達到設(shè)計任務(wù)書的要求，例如良好的耐波性能，操縱性，預(yù)期的速度，續(xù)航力，艙容和載重量。進一步講，基本設(shè)計還包括校核和修改，以滿足貨物裝卸能力，居位艙，客房設(shè)施，分艙和穩(wěn)性標(biāo)準(zhǔn)，干舷和噸位測量，所有這些都是將船舶當(dāng)成運輸、工業(yè)化或服務(wù)系統(tǒng)的一部分。Basicdesignencompassesb

8、細設(shè)計。合同設(shè)計，顧名思義，需要做出圖紙和詳細說明書，以便船廠去投標(biāo)和簽約。一套良好的合同圖紙和詳細說明書應(yīng)當(dāng)是非常清晰和詳細的，以避免高成本的偶然性項目，并使投標(biāo)者不出現(xiàn)模糊不請的或specificationswhichfmanintegralpartoftheshipbuildingcontractdocument.Itencompassesonemeloopsaroundthedesignspiraltherebyfurtherr

13、，形成了一套船舶建造合同文件。它包括圍繞設(shè)計螺旋的一個或多個環(huán)節(jié)，因為對初步設(shè)計作進一步優(yōu)化。這一階段更加準(zhǔn)確地描繪船舶特征，如基于一套光滑線組成的船體線型，基于模型試驗的主機功率匹配，船舶耐波性與操縱性，螺旋槳數(shù)量對型線的影響，結(jié)構(gòu)細節(jié)，不同類型鋼材的使用，肋骨間距和形式等。再合同涉及元素中最重要的是考慮了船舶各個主要分段設(shè)備的重量及其位置之后的船舶重量與重心的估算。最終的總布置圖也是在這一階段確定下來，這就將總體積、貨物區(qū)域、機器設(shè)

14、備、儲物設(shè)備、燃油、淡水、居住與公用艙室以及幾何相互關(guān)系固定下來。還包括與其它因素例如貨物裝卸裝備、機器設(shè)備等的關(guān)系也都確定下來。補充說明書描述了船體和舾裝的質(zhì)量標(biāo)準(zhǔn)，以及各個機器、設(shè)備的預(yù)期性能。這些說明書還敘述了模型試驗和實驗情況，一表明船舶設(shè)計師成功的，船舶是可接受的。表1.1列出了一艘大型船舶在合同設(shè)計中的典型圖紙清單。小型船、不復(fù)雜的船客不要求具備表中所列的每一圖紙，但該表確實顯示了合同涉及中考慮的細致程度。d.Detaild
