In case securing equipment’s on board a Container ship is worn beyond use and new equipment has to be ordered. In that connection, please mark which of the below statement that is correct:
The equipment should be as specified in the container securing manual.
The equipment should be certified by the classification society.
The equipment should be of similar type and size.
In connection with loading of containers, the correct information about the weight and location of containers are crucial for ships stability and strength, as well as the stowing and securing of them. Where would you look for information on how to provide proper securing of the containers?
In the ISM system.
In the Container securing manual.
In the loading manual.
In the bottom plating in a ballast tank, the thickness diminution may be due to, general corrosion, pitting corrosion, grooving corrosion or erosion corrosion. Where would you look for pitting corrosion?
On horizontal flanges.
Under suction heads for ballast line.
In way of cut-outs for drainage.
It is very important to be familiar with the technical terminology when dealing with container ships. Is a floor a part of the:
Double bottom structure.
Maintenance of loose stowing and securing equipment is very important for the safety of the cargo during transportation overseas, such as (please indicate which is incorrect):
Semi-automatic twist locks.
Manual twist locks.
Sliding base sockets.
On a container ship, which part of the ship represents the web of hull girder?
The longitudinal bulkheads.
The longitudinal bulkheads and the ship sides.
The transverse bulkheads.
Pitting corrosion is most commonly found on horizontal surface in:
Heavy fuel oil tanks.
Regarding inspection of the cargo holds, where is the least likely location for finding cracks?
At the cell guides.
At corner of stringer decks.
At hatch corner.
Reporting in PIMS of the results from the inspection is very important Checklist and Narrative reports. Consider you have carried out an inspection in a ballast tank. The tank was found in order except for an indention in the ship side, which has caused a slight buckling of two side longitudinal. How would you report this?
Fill in the checklist, take some photo and make a narrative report where you describe the indent and location.
Fill in the checklist and take some photos.
Fill in the checklist.
Similar to Classification Society, the Owner also has acceptance criteria to be used when deficiencies are found. These acceptance criteria should normally be somewhat stricter than the class. Where do you find Owner’s acceptance criteria?
In the working guidance by chief officer.
In the PIMS manual on board.
In the ISM system Reg. 10.
Some areas of minimal attention with respect to coating, during inspection of ballast tanks are:
Inside edge of cut-outs.
Edge part of stiffeners.
On the web of stiffeners.
The class society has acceptance criteria for different types of deficiencies, such as: which two alternatives are not correct?
The coating condition in the ballast tanks may be rated as: indicate which of these coating conditions require annual follow up of the ballast tank in question by the class surveyor?
The fore ship may suffer damage due to impact from the sea. Which structural element will then suffer the most significant damage?
The shell plating.
The stiffeners from the shell plating.
The web frames and girders.
The function of a loaded beam is to transfer loads towards the end supports (in shear). Which part of beam has this function?
Both web and flange.
The hull girder of a container ship is as other ships subject to tension and compression due to the loads from the lightweight and cargo, and the counteracting buoyancy loads. Since the container ship normally operates in a hogging loading condition, where would you expect tension stresses in the hull girder?
In the deck area.
In the bottom area.
The pressure testing to prove strength and tightness is not required for which of the following items?
This is another example of good condition but what do we call the deficiency you can see on the coating? Click on the right option:
What is assumed by the class for retention of class?
Owner/manager to ensure adequate handling and manning of the ship.
Owner/manager to ensure adequate maintenance, handling and manning of the ship.
Owner to ensure adequate maintenance.
Owner to ensure that the vessel is presented for surveys.
What is the Integrated Survey Program (ISP)?
A maintenance program for cargo ships.
A hull inspection and maintenance program for container ships.
A maintenance system for machinery on container ships.
A survey program, which is integrated in the maintenance system on board.
What is the classification in the SiO phase?
To verify that the standard of ship in operation (SiO) acceptable after conversion.
Verify that the standard of the ship is acceptable after damage repairs.
To verify that the standard of the ship is acceptable through a system periodical surveys.
To make sure that the vessel is well maintained.
What is the condition for the 5-year validity of the class Certificate?
That surveys are carried out every 2,5 years and with satisfactory result.
That survey is carried out every 5 years with satisfactory result.
That annual surveys are carried out with satisfactory result.
That all condition of class (CC) are carried out.
When doing inspections of the upper deck area, where would you not find cracks immediately?
At the hatch coaming stays.
At the lashing bridges connection to the deck.
At the middle of hatch end coaming.
At the hatch end coaming brackets.
When looking for cracks in the ship structure like for instance the bottom structure, would you then first focus on:
The middle of the plate.
At the connection between plate and stiffeners.
At the connection between stiffeners and girders.
Where would you look for cracks in the side ballast tanks in the first place?
At the tank top longitudinal connection to the web frames.
At ship side longitudinal connection to the web frames below waterline.
At the longitudinal bulkhead longitudinal connection to the web frames.
Which is outside the scope of Planned Inspection and Maintenance System (PIMS)?
Dry docking/bottom survey.
Survey of ballast tanks with Fair coating.
Survey of container fittings.

Which is required from the crew on board for practising of ISP?
Carry out inspections in accordance with the maintenance system on board, which has been accepted by the class.
Carry out inspections when deemed necessary.
Carry out inspections and report in accordance with the maintenance system, which has been accepted by the class.
Carry out inspections and submit report to the class.
Which of the following items is not mandatory in the PIMS?
Deck and hatches.
Piping system outside machinery space.
Which of the following precautions while pressure testing of a ballast tank is most important?
Filling should be to the top of tank.
Venting done through the air pipes.
Hatch covers and/or manhole covers should be kept open during pressure testing.
