標(biāo)題: 泰國(guó)3400DWT供油船氣囊下水方案中英雙語(yǔ)版

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

[attach]9144[/attach]

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

5. weather condition requirement when launching：

下水時(shí)氣候要求：

5.1 The force of the wind should be less than 5 level

visibility should be over 10 meter

no heavy fog、wind、rain etc.

風(fēng)力應(yīng)該小于5級(jí)，能見(jiàn)度要超過(guò)10m，沒(méi)有大霧，風(fēng)雨天氣。

5.2 before launching, we should confirm height of tide is satisfied。

在下水之前，必須確認(rèn)潮汐水高度滿足下水要求

6. working process of slipping to the water

The process begins only after the sections building finished and checked out.

下水的工作程序

下水進(jìn)行必須在船建造結(jié)束，且驗(yàn)檢合格

6.1 preparation

準(zhǔn)備工作

6.1.1 all tools should be on site.

所有設(shè)備工具須放置現(xiàn)場(chǎng)

6.1.2 Place the air-bags according to the drawings we offered.

如布置圖所示布置氣囊

6.1.3 set two over 20t lugs at the stem 1.5m from the baseline, and the location should not be too low .

燒焊在船舶距基線1.5m高度2個(gè)20T的耳板。高度不能太低。

6.1.4 Connect the hoist and the hook tightly , the wire rope must meet requirements；set the bitts、winch(10t)and wire rope as the drawings we offered.

鏈接卷?yè)P(yáng)機(jī)和脫鉤。鋼絲繩須滿足要求。如圖所示布置地牛，絞車(chē)（10T）及鋼絲繩

6.1.5 Clean the things like scaffoldings、welders, which can hinder the launching process

清除像支架，焊機(jī)之類可能阻礙下水過(guò)程的物品

6.1.6 Measure the water level and adjust the launching process by it.

測(cè)量水的高度，隨時(shí)調(diào)整下水方案

6.1 lifting process

起墩過(guò)程·

6.2.1 Charge the air-bags to 0.07Mpa from the end of the ship to the beginning.

anchor the ship, take the air-bags back ,and the process finished

拋錨泊船，回收氣囊，下水完成。
