A full set of maintenance manuals.
A training video or CBT supplied by the manufacturer and approved by the IMO.
According to SOLAS 1974 regulation III/9, where do posters or signs illustrating the procedures for operating survival craft have to be located?
In the vicinity of survival craft and their launching.
On the bridge.
In all passenger cabin alleyways.
On the inside of the forward hatches of all enclosed lifeboats.
All inspections, other than weekly and monthly and any servicing and repair, other than routine, should be conducted by which of the following persons?
The Master.
A manufacturer’s representative or a person appropriately trained and certified by the manufacturer for the work to be done.
A Company Superintendent.
A Senior Officer of a fitter suitable qualified and holding a certificate in lifeboat maintenance.
Before launching a free-fall lifeboat, which of the following items is it essential to check?
That there is a clear launch path.
That there is adequate depth of water.
That all personnel are safely strapped in to their seats.
That additional securing straps have been released and locking pins removed.
回答
By SOLAS, how often does a free-fall lifeboat normally have to be launched by free-fall mode and maneuvered in the water by its assigned operating crew?
At least once a month.
At least once every 3 months.
At least once every 6 months.
At least once a year.
Details of specific responsibilities assigned to crew members during the launch of the lifeboat are shown where?
In the ship’s Personnel Manual.
On the Muster List.
On the main notice board.
On the Bridge Watch Keeping Schedule.
How is the hook held in the closed position?
By a hinged catch.
By the weight of the lifeboat alone.
By the remote release handle.
By a locking pin.
How is the release hook in this mechanism opened?
Hydraulic pressure is applied under the lifeboat, taking the strain off the hook and enabling it to be manually released by the crew.
Pneumatic pressure is applied directly to the hook to open it.
The lifeboat coxswain moves a switch and an electric signal is sent to the automatic release actuator.
Hydraulic pressure turns the hinged catch clear and the weight of the lifeboat opens the hook.
If the remote release handle fails to operate properly, what is the emergency procedure?
The glass panel in the casing of the hydraulic cylinder must be smashed and the screw arrangement turned, to build up the pressure in the cylinder and extends the piston to turn the hinged catch.
The locking pin must be withdrawn from the safety bolt and the hinged catch manually forced clear, allowing the hook to open.
Pressurize the hydraulic cylinder by connecting the emergency gas supply.
Use the emergency handle as a crowbar to force open the hook.
In preparation for recovery of the lifeboat, the pressure in the hydraulic cylinder must be relieved. How is this done?
By opening the bypass valve next to the remote release handle.
By manually rotating the end screw on the cylinder in an anti-clockwise direction.
By applying a downward pressure on the securing hook, causing the hinged catch to rotate and forcing the piston back into the housing.
By closing the bypass valve and operating the remote release handle until the pressure dissipates and the handle action goes slack.
In the case study into the accident on board the Philippine-flagged bulk carrier “Washington Trader”, the Australian marine accident investigators found the reset lever extremely stiff. They concluded this was due to:
Poor design.
Poor illumination.
Lack of use.
Lack of understanding.
In the case study into the accident on board the Turkish-flagged bulk carrier “Gulsar Ana” in 2001, which of the following deficiencies were listed by the authorities as contributing to the accident with the lifeboat?
Lack of information on the equipment.
Poor maintenance on the hook.
Poor understanding by the crew.
The locking pin missing.
回答
In which direction must the end screw be rotated to pressurize the hydraulic cylinder during the emergency release procedure?

STCW.
MSC/Circ. 1093.
The Life-Saving Appliances Code.
MARPOL.
Is it necessary for a crew-member to remain outside this type of lifeboat during release?
No.
Yes.
MSC/Circ. 1093 requires which of the following to be onboard for use in all operations involving the inspection, maintenance, adjustment, and re-setting of the lifeboat and associated equipment, such as davits or release gear?
A full set of maintenance manuals.
A specialized tool-kit supplied by the manufacturer.
Original certificates of competency in lifeboat maintenance for any personnel involved in inspections and maintenance of such equipment.
A training manual, video or CBT supplied by the manufacturer and endorsed by the IMO.
Once the hinged catch is rotated clear during release, what actually opens the hook?
The weight of the lifeboat alone.
Rotation of the hydraulic release bypass valve by the coxswain.
Increasing pressure within the hydraulic cylinder.
Extension of the hydraulic piston.
Prior to operating the remote release handle, which of the following operations must be performed?
The bypass valve must be closed.
The safety pin must be replaced.
The safety catch must be removed.
The bypass valve must be opened.
Prior to recovery of the lifeboat after a drill, the pressure in the hydraulic cylinder is relieved. Why is this an essential requirement?
In order to prevent damage to the piston, which might cause a failure of the release mechanism in a real emergency situation.
So that all components are restored back to their original positions ready for the next drill.
So that the hinged catch rotates back to the locked position.
It acts as an additional safeguard, in case the locking pins have not been properly replaced.
