Hello everyone,

I hope these stupid questions won't make you feel bored. I really want to know the answer.

1. How come there is a big door at the back of the ship in 蛮琍腹? What is it use for? allow cars and trucks to drive in from the pier?

2. I see every ship have a radar rotating at the top, what is that radar use for? detecting weather? detecting sea traffic? or detecting terrain underwater?

3. What communication channel is for marine use? what frequencies? any special frequencies for long range communication? When does the crew need to contact with marine department? or other government unit (e.g. customs, police...)

4. When a ship big like Leo need to park in Ocean terminal, do they need to make contact to anyone for request for parking clearance? I don't see any tower in the ocean terminal.

5. Does the cruise ship have to keep at least one engine on when they are on water? Will they sink if everything turns off completely?

best regards,
Alkit

2.你所講嘅係平面搜索雷達，負責搜索海平面上一切嘅東西，包括船隻、島嶼等等。至於天上同水下嘅則交由對空搜索雷達同聲納負責，不過郵輪無需要裝備，因為佢地唔係作戰船隻:)

4.當大型船隻需要靠岸時，駕駛員會轉移至Bridge Wind繼續進行靠岸作業。

5.基本上大型船隻由竣工後直至下一次入塢都會維持動力系統運轉，因為重新點爐需要大量時間同燃料。一般大型船隻重新點爐需要四小時以上，緊急時也要大概兩小時，因此，就算是靠岸或錨泊後，動力系統仍會維持低功率運轉。

Thank you very much for your answer!!

Do they really not install radar for detecting ┏ or  ?

How many engines does a cruiseliner has? For example, Star Leo, QE 2, QM 2. When they are opering in idle power, do they still need to keep ALL engines running? Or just keeping at least one engine running is OK?

首先要說明一樣野，Radar中文叫雷達，係一種利用丒磁波(即係幅蓙E反射黎確認目標位置、距離丒機器，常見嘅有平面搜索雷達同對空搜索雷達。而搜索水下目標丒機器叫聲納，英文係Sonar，佢丒工作模式同雷達阐位多，同樣係利用回波黎確認目標位置同距離，只不過聲納發出嘅係聲波。
郵輥Eo需要知道水下情況，因為我之前已經講過，佢啁濻作戰船丒。
至丒探測海底地形係海洋測量船丒工作，竵E舆鸌P郵輥E隆�

有關郵輥E鳈C丒數目我啁沐楚，不過目前丒趤E輦S採用燃氣渦輥EC(Gas Turbine)，因為燃氣渦輥EC結丒簛E巍Ⅲw積小，蜇要係燃氣渦輥EC丒工作詠E粝喈數停浅＿m合郵輥E５珎S燃氣渦輥EC耗油量相當高，低速巡航時效率低，因此郵輥E紓S採用巡航用燃氣渦輥EC。儘管如此，即使係巡航用燃氣渦輥EC，耗油量仍然比其他機種要高。而歷史比較耐丒郵輥E例如QE2)採用丒一般係柴油機。

無錯，除左葋E]同其他緊急事故之外，大型船丒都維持整個丒力系統低功率運轉(只係空轉，係啁炳駁落輸出軸度丒)

I ya, I can't read your post properly even I try setting different language coding in IE. I believe you are posting something very interesting!
