Study Notes

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.
