CFRS Regulations Quiz

DG Study - CFRS Regulations

• Tanker/Tankship Regulations: No oil transfer is permitted unless all transfer system parts are properly aligned. Flammable vapor prevention is crucial.
• Deck Seal Purpose: Prevents flammable vapors from entering machinery spaces.
• Oil Pollution Emergency Plan: Must include plan explanation and purpose, along with a diagram of ship transfer piping. The master is responsible for the Oil Record Book.
• Transfer Operations: Operations guidelines should detail how long oil transfer inspection records must be kept.
• Liquid PV Breaker: Used to relieve any vacuum in tanks; refill the breaker before proceeding with other tasks.
• Crew Training (Lifesaving): New crew must be trained on life-saving equipment within two weeks.
• Rocket-Type Line Throwing Appliances: Oceangoing vessels with less than 140GT are not required to carry these.
• Sanitary Inspections: The Master and Chief Engineer are responsible for conducting sanitary inspections.
• Firefighters Lifeline Requirements: Must be made of corrosion-resistant steel or bronze, at least 50 feet long.

Additional Cargo Regulations

• Hydroscopic Cargo: Require constant ventilation, especially when moving between warm and cold climates. Non-hydroscopic cargo requires less ventilation.
• Flame Screens: Installed on tank vents to prevent explosions, allowing vapors but not flames to pass.
• Tank Valve Procedure: Securely close tank valves by opening and closing them a halfway before finally fully closing.
• Crude Oil Classification: Most crude oils are classified as either C or D.
• Casualty: A vessel in danger of sinking while en route to drydock due to a ballast problem may be claimed for total loss.
• Salvage Lien: The first settlement claim against a vessel in a marine accident due to salvage of the vessel.
• Bill of Lading: A document signed by the Master detailing good delivery to a ship.
• Bow and Stern Lines Function: Reduce vessel movement during docking.
• Anchor and Mooring: Using anchors for vessel movement in restricted waters; chain must be marked with red paint.
• Rivers & Ice Concentration: Deepest water is found on the outside of a river bend. Ice concentration is measured in tenths.
• Ice Pack Navigation: "Close Pack" is considered 7-8 tenths, "Open Pack" 4-6 tenths, "Very Open" is 1-3 tenths; the vessel should enter the pack ice at an angle perpendicular to the ice, and a vessel's draft should be no more than 2-3 feet.
• Whiteout Conditions: Snow obliterates visibility, and polar regions need precautions. White glare in the sky may indicate nearby ice.
• Flow State: The saturation of a dry bulk product with liquid to the point when it acts like a liquid.
• Tare Weight of Container: Weight of an empty container.
• Dew Point: Air inside the cargo hold is higher than outside, ventilation is not necessary.
• Moisture Equilibrium Chart: Used for determining the dew point temperature of air around a hygroscopic commodity.
• High-Value or easily Pilferable Cargo: "Special Cargo"

Vessel Requirements and Safety Regulations

• Overcarriage: Best prevented by inspection of the hold after cargo discharge.
• Deadweight Cargo: Stowage factor below 40.
• Cargo Measurement (Stowage Factor Above 40):
• Tank Inspection: Important for loading and unloading liquid cargo.
• Tainting: Damage caused by fumes and vapors from liquids, solids, or gases.
• Cavitation: Voids on propeller blades affecting efficiency.
• Gross Tonnage: Derived from the ship's volume in cubic feet, divided by 100, excluding exempted spaces.
• Net Tonnage: Spaces are not generally used for cargo storage (crew, etc.).

Anchoring, Speed, and Vessel Movement

• Maximum Safe Docking Speed: .2 feet per second.
• Anchoring Depth: 1.5 times the depth using offshore anchors..
• Squat: Decrease in pressure on the hull due to vessel speed in shallow water. The larger the vessel the greater the effect.
• Turning with Fixed Objects: The ship's turn rate can increase or decrease based on the drift of a fixed object during turns.
• Shallow Water Effects: Turn rates change based on water depth (less than 1.5 x vessel's draft).
• Pitching: Measurement of the time required for a vessel to transition to bow/stern up and then down.
• Advance: The gain in distance parallel to the original course.
• Transfer: Distance gained at right angles to the original course.
• Kick: Vessel's stern movement upon hard-over helm.
• Head Reach: The distance needed from the vessel taking action to stop until remaining stationary in the water

Other Ship Operations and Regulations

• Tactical Diameter: Vessel movement at right angles to the original course (180 degrees movement).
• Turning Circle: Path created by the ship's center of gravity during a 180-degree turn.
• Pivot Points: Pivot points are located 1/4 and 1/2 away from the stern and bow, respectively, when backing and coming ahead.
• Sidewise Force: Propeller's effect on the ship's sideways movement.
• Balanced Spade Rudder: Loss of effectiveness beyond 10 degrees.
• Wake Fraction: The ratio of the wake speed to the ship's speed.
• Wake Effects: The water flow pattern around the hull.
• Slipstream: Propeller's effect on the shape of the water flow.
• National Cargo Bureau (NCB): They verify cargo suitability (grain) before loading.
• Maneuvering Characteristics: Data is placed in the ship's pilothouse.
• ABS Inspections (Load Line, Cargo): Load line certificates can be extended, annual surveys within 3 months.
• Safety Construction, Equipment, and Materials: Minimum standards in building and operating cargo ships, set by IMO.
• USCG (United States Coast Guard): Approves stability and trim booklets.

Voyage Charters and Notices

• Voyage Charter Party: Contract determining cargo movement rates.
• Notice of Readiness: When the vessel is ready to be loaded.
