3400t oil supply ship

Launching technology by using airbags

3400DWT供油船應(yīng)用氣囊下水方案

1. This technology is used to launch 3400t oil supply ship built in Thailand, the other ships’ launching process can refer to this technology .

此方案應(yīng)用于建造在泰國(guó)的供油船下水，其他船舶下水也可借鑒。

2. quoted standard：

CB/T3975-1996 airbags for ship slipping and launching

Loa=90m         B=15m         TF=1.674m  Ta=3.164m

D=6.8m               W=1850 t  

  下水船的相關(guān)數(shù)據(jù)：

  總長(zhǎng)=90m   型寬=15m    艏吃水=1.674 尾吃水=3.164

  型深=6.8m  自重=1850T

2.2 main parameter of the slipway

船臺(tái)的主要參數(shù)

2.2.1 All we know is that the slipway is horizontal now。

我們現(xiàn)在只知道船臺(tái)是水平的·

2.2.2 rebuild requirement of the silpway：

關(guān)于船臺(tái)改造的要求

a. format the horizontal part of the slipway, and remove the object which can break airbags；

修理船臺(tái)水平的地方，并且清除可能對(duì)氣囊造成破壞的障礙物

b. the end of the horizontal slipway to the mean tide lever ,the grade should be 1/30~1/35 ,the bearing capacity is over 0.1Mpa.

船臺(tái)末端，接近水位的位置的坡度應(yīng)該在1/30~1/35之間，并且能承受0.1Mpa的壓力

c. Under the water, the grade should be 1/15,the length is that， when launching ,the depth of the water at the end of the slipway should over1.8m.

在水中的船臺(tái)坡度應(yīng)該在1/15，并且末端水深要超過(guò)1.8m

3. requirement of the main equipments

主要的設(shè)備

Air-bags type is 6 layers φ1.5×15,number is 20.

pillar height：H=0.9m：

Q=π(D-H)/2 L· P·N ·Cb =3.14(1.5-0.9)/2×15×0.16×9.8×10×16×0.7297=2586(t)

起墩過(guò)程中承載力的計(jì)算：

安全系數(shù)：K=2586/1850=1.39＞1.26

Airbag’s height：H=0.5m

safety factor：K=4311/1850=2.33＞1.26（satisfied）

the tractive force should be

牽引力

F= W*sinactank = 1850×sinactan1/80=23T
