1. What are the responsibilities of the Second Engineer on board a ship?

The responsibilities of the Second Engineer include the following.

(1) Sea watch from 1200~1600 hours and from 0000~0400 hours every day except for UMS operation.

(2) Port watch as designated by the Chief Engineer.

(3) Maintenance and repair of the following machines and spare parts: generator engine, generator, fuel oil purifier, emergency generator, fuel oil control and other machines designated by the Chief Engineer.

(4) Maintenance records of the generator engine, purifier, boiler and other equipments.

(5) Sounding the fuel and lube oil tanks and ma-ki-ng records of the daily consumption rate.

(6) Requisition for spare parts of the machines and equipment under his charge.

(7) Any other duties designated by the Chief Engineer.

尽管二管轮和三管轮在不同的公司的职责有所区别，但是，基本工作内容还是很相似的。希望应该船员在面试前要仔细回忆一下你在前一条船做二管轮时的具体职责，并能用较流利的英文说出来。

2. What is your emergency position on the Muster List?

Basically, my position is to control and operate the auxiliary generator in the engine room.

根据SOLAS公约和ISM规则，应急部署表的位置对每位船员都很重要，应该知道自己在不同应急事件时所处的位置和职责。

3. What will you do if your hear heavy noise coming from the lubricating oil pump?

I shall start the standby lubricating oil pump first and foremost, and then stop the heavy noise lubrication oil pump for emergency check.

对于一般的机械故障，二管轮应该能判定他们的基本原因并能采取相应的对策；如果自己不能判定故障原因的话，应该及时向大管轮或轮机长汇报。

4. Which machineries and control of spare parts should 2nd Engineer be in charge of?

Usually, the 2nd Engineer is in charge of such machines, engines and spare parts as generator engine, generator, fuel oil purifier, emergency generator, lifeboat engine, emergency fire pump, fuel oil control, deck machinery and others designed by the Chief Engineer.

总之，二管轮主管负责机舱的辅助机械，对这些辅助机械的名称，应该能用流利的英文说出，还要知道这些辅助机械的基本功能、原理和觉见故障。

5. Describe the procedure to start a boiler.
