船舶各部位及艙室名稱.doc

1、一、船舶各部位及艙室名稱有關(guān)概念船首 (head)：船的前端部位。它的兩側(cè)船殼彎曲處叫首舷(bow)。船尾 (stern)：船的后端部位。它的兩側(cè)船殼彎曲處叫尾舷(quarter)。舭部 (bilge) ：船舷側(cè)板與船底板交結(jié)的部位。附：專業(yè)英語單詞1. starboard: 右舷2. port: 左舷3. abeam: 正橫4. hatch: 艙口5. cargo hold: 貨艙6. inner bottom plating: 內(nèi)底板7. bottom plating:船底板8. double bottom: 雙底層9. forcastle deck: 首樓甲板10. poop deck:

2、 尾樓甲板11. saloon deck:上層建筑甲板12. promenade deck:起居甲板13. watrtight transverse bulkhead:14. forepeak tank: 首尖艙15. afterpeak tank: 尾尖艙16. engine room:機(jī)艙17. collision bulkhead: 防撞艙壁水密橫艙壁船舶尺度最大尺度： 也稱全部尺度或周界尺度， 它可以決定?？看a頭泊位的長度， 是否可以從橋下通過，進(jìn)某一船塢。全長（最大長度） ：指船舶最前端與最后端之間（包括外板和兩端永久性固定突出物在內(nèi)）水平距離。全寬（最大寬度） ：包括船舶外板和永久

3、性固定突出物在內(nèi)的垂直于縱中線面的最大水平距離。最大高度： 自龍骨下邊致船舶最高點(diǎn)之間的垂直距離。 它減去吃水， 即可得水面以上的船舶高度。登記尺度登記尺度： 是主管機(jī)關(guān)在登記船舶和計(jì)算船舶總噸位、凈噸位時(shí)所使用的尺度，它載明于噸位證書上。登記長度： 在上甲板的上表面上，自首柱前緣到尾柱后緣的水平距離；無尾柱時(shí)， 則量至舵桿中心。登記寬度：在船舶最大寬度處，兩舷外板外表面之間的水平距離。登記深度： 在船舶縱中剖面的登記長度中點(diǎn)處，從上甲板下表面往下量至內(nèi)底板上表面的垂直距離。船型尺度：船長：沿夏季載重水線，自首緣量致尾柱后緣的水平距離，又稱兩柱長。型寬：船體最寬處兩舷肋骨外緣之間的水平距離。型

4、深：在船長中點(diǎn)處，自平板龍骨上緣量至干舷甲板橫梁舷端上緣的垂直距離。船舶吃水、噸位和標(biāo)志型吃水：自平板龍骨上緣量至水面的垂直距離。加上平板龍骨的厚度，為實(shí)際吃水。重量噸：表示船舶重量，也可表明船舶的載運(yùn)能力?？煞峙潘亢洼d重量。排水量：指船舶在水中所排開的同體積水的重量。滿載排水量：船舶裝足貨物、旅客、燃料、淡水和供應(yīng)品，并具有規(guī)定的安全干舷時(shí)的排水量，通常是指船舶在海水中達(dá)到夏季載重線時(shí)的排水量?？沾潘浚捍皼]有裝貨物、旅客、燃料、淡水和供應(yīng)品等時(shí)的排水量。載重量：或稱總載重量，表示船舶所具有的載重能力。即：載重量=滿載排水量空船排水量凈載重量：表示實(shí)際可裝載貨物的噸數(shù)，它隨具體航次所需

5、要備品儲(chǔ)備量不同而變化。凈載重量 =總載重量燃料、淡水、供應(yīng)品和備料等的重量容積噸位容積噸位： 是丈量船舶容積后經(jīng)換算而得出的噸位，它表示船舶所具有空間的大小，又稱登記噸?？倗嵨?9gross tonnage0：表示建造船舶規(guī)模的通用統(tǒng)計(jì)單位，也是計(jì)算海事陪償?shù)幕鶞?zhǔn)之一。從船上所有固定圍蔽處所的容積中，扣除上甲板以上的航行工作處所，航行設(shè)備處所、 安全設(shè)備處所、通風(fēng)采光處所、機(jī)械處所、錨設(shè)備處所、升降口及出入艙口、廚房、衛(wèi)生間、工作間、儲(chǔ)藏室、奪載水艙等所占容積后，除以2.83 即得該船的總噸位。其丈量的具體規(guī)定可參閱“船舶噸位丈量規(guī)范”。凈噸位（ net tonnage）：從總?cè)莘e中扣除不能
