Self Assessment - BSMARE SI-DELTA NSA

An automated system is experiencing intermittent faults due to unstable signal transmission. What is a common cause of this problem?

• Calibration errors affecting sensor readings

• Excessive hydraulic pressure in the system

• Signal transmission delays from loose wiring

• Incorrect weight measurements by sensors

What is the recommended coating for the windlass motor connections?

• CRC Soft Seal to enhance protective sealing

• Molykote grease for lubrication stability

• Lithium grease to ensure system lubrication

• Silicone spray for high-performance motors

What role do fuel oil transfer pumps serve?

• Supplying water to the ship’s fire hoses

• Transferring fuel between onboard tanks

• Removing water from bilge compartments

• Discharging fuel cargo during operations

A suction pipe system experiences frequent pump clogging issues. What feature could help protect the pump from such problems?

• To adjust machinery suction at lower speeds

• To regulate suction pressure and flow rates

• To protect pumps by filtering larger solids

• To filter oil residues and increase flow control

Why are life rafts fitted with a hydrostatic release unit?

• To enable manual deployment during emergencies

• To inflate the raft faster with compressed gas

• To provide additional space for lifeboat evacuation

• To automatically deploy the raft if the ship sinks

After an incident involving a cargo crane, what is the importance of post-incident analysis?

• To identify areas of improvement in the system

• To minimize downtime in similar future operations

• To ensure accurate alignment of system sensors

• To reduce operator errors during future tasks

Why is data logging essential in troubleshooting?

• To record and analyze performance trends over time

• To monitor voltage fluctuations in power supply systems

• To simulate faults for real-time system testing

• To dynamically adjust tension and weight sensors

A sewage system struggles with sludge movement. What change could improve performance?

• Replacing it with a centrifugal ballast pump

• Installing a hydrophore freshwater system

• Using a submersible macerator pump unit

• Switching to a high-pressure fire pump system

What maintenance action is recommended for hatch landing pads?

• Replace all gaskets with those of higher compression

• Align steel plates monthly for consistent pressure

• Clean debris regularly to improve sealing efficiency

• Repair when wear exceeds 4 mm for pressure balance

Why are screw pumps suitable for high-viscosity liquids?

• They rely on suction to remove liquids.

• They use blades to grind the waste solids.

• They provide a reliable and constant flow.

• They work in direct contact with fluids.
