Questions and Answers
What is the purpose of the sea water inlet valve on the bilge pump?
The sea water inlet valve on the bilge pump allows seawater to be used to operate the bilge pump.
What is the purpose of the air release on the separator shell?
The air release on the separator shell allows air to be released from the separator, preventing air pockets from forming.
What is the purpose of the oil content monitor on the overboard discharge?
The oil content monitor on the overboard discharge measures the oil content of the water being discharged overboard to ensure it meets environmental regulations.

Study Notes
Bilge Pumping and Oily Water Separators
- Sea water inlet valve on bilge pump: allows sea water to enter the bilge pump to flush out bilge water
- Air release on separator shell: releases air that may have accumulated in the separator shell
- Oil content monitor on overboard discharge: monitors the oil content in the overboard discharge to ensure it meets regulations
- Baffle plates inside the separator shell: help to separate oil from water by slowing down the flow and allowing gravity to separate the two fluids
- Relief valve on separator shell: releases excess pressure in the separator shell to prevent damage
Microbiological Contamination of Marine Gas Oil
- Conditions for microbial growth: water, temperature, nutrients, and microorganisms must be present
- Effects of microbiological growth: corrosion of tanks and pipes, fuel contamination, and engine problems
- Detection of contamination: through fuel sampling and analysis
- Reducing the risk of contamination: by using biocides, maintaining clean tanks, and monitoring fuel quality
- Removing contamination: through fuel treatment and tank cleaning
Calcium Hypochlorite
- Precautions for use and storage: handle with gloves and goggles, store in a well-ventilated area, and avoid mixing with other chemicals
Sewage Treatment Plant
- Physical properties to monitor: pH, temperature, dissolved oxygen, and biochemical oxygen demand
Environmental Effects
- Green House Effect: a process by which certain gases in the atmosphere trap heat and contribute to global warming
- Ozone depletion: the reduction of ozone in the stratosphere due to the presence of chlorofluorocarbons and other substances
Refrigeration System
- Effect of undercharge: reduced cooling capacity, increased energy consumption, and potential system failure
Micro-organisms in Water
- Types of micro-organisms: bacteria, viruses, and protozoa
Silver Ion Sterilizer
- Operation: uses silver ions to sterilize water by inhibiting microbial growth
Hydraulic Stabilising System
- Active fin hydraulic stabilising operating system: fitted to a vessel to reduce rolling and improve stability
Hydrodynamic Forces
- Forces that act on a vessel: frictional resistance, wave resistance, and air resistance
Certificates of Competency for Engineers
- Examination details: administered by the Scottish Qualifications Authority on behalf of the Maritime and Coastguard Agency
