DG Study CFRs D T Tanker, Tankship T I C Cargo Vessel C N D Dangerous, Hazardous D Cargo O P Pollution, 33 P C U Uninspected, 46 U E L Load Lines L T P Small Pax S 33 -according to US regulations states that no person may transfer oil to or from a vessel unless all parts of the transfer system have been properly lined up -purpose of a deck seal in an inert gas system is to prevent flammable vapors from entering a machinery space -according to the Coast Guard Regulations, the shipboard Oil Pollution Emergency Plan must include an explanation and purpose of the plan; try 33 CFR 151.26 -the transfer procedures required to be followed on tankships shall contain a line diagram of the vessel’s transfer piping -under normal operating conditions aboard a ship, the master has the overall responsibility in maintaining the Oil Record Book -subchapter O contains “Oil and Hazardous Material Transfer Operations” such as “how long shall a declaration of inspection be kept aboard between two vessels transferring oil” = 1 month 46 -the liquid PV breaker has acted to relieve a vacuum in a tank, which action must be taken in regards to the PV-breaker before continuing; refill the beaker with liquid -a new crewman reports on board and must be trained in the use of the ship’s lifesaving appliances within 2 weeks -a vessel NOT required to carry a rocket-type line throwing appliance is an oceangoing vessel of 140GT; try subchapters r-v 166-199 -on a tank ship, the master and c/e are responsible for sanitary inspections -firefighters lifeline must be made of steel or bronze, corrosion resistant, and no less than 50’ in length; try 46 cfr 96.35-5 49 -no separation is required of containers because they are exempt Hydroscopic Cargo - cargo that can absorb moisture from the air or in the form of gas. You must ventilate constantly and vigorously if transitting from warm to cold climates. Non-hydroscopic cargo going from cold to hot climate there is little need to ventilate. A heated bulkhead will raise the vapor pressure of a hygroscopic commodity. Flame Screens - installed on tank vents that may contain combustible gases are designed to prevent explosions by dissipating the heat of an external flame. Permits the passage of vapor but not of flame. Tank Valve - to ensure proper seating when closing a valve on a tank, the valve should be closed, opened a half a turn, then closed again. Crude Oils Classified - most crude oils are classified as C or D Ship’s Business -a ballasted vessel sinks enroute to a dry dock, under these circumstances a vessel’s owner can claim actual total loss -a salvage lien is the first lien against a vessel that is settled first -can get 2 years imprisonment or $1000 fine by failing to give aid in the case of a marine casualty -Shipping Articles are a contract of agreement between the members of the crew and Master Bill of Lading -document that the Master signs stating the terms that goods were delivered and received by the ship Safety Shackle - identified by the design of the pin, ie. it has holes to mouse Bow and Stern Lines- primary function is to reduce the fore and aft motion of a docked vessel Block and Tackle -rove to advantage when the hauling part leads through the movable block Anchor and Mooring -entire shot of anchor chain is painted red indicates it is next to the last shot of chain -the use of an anchor to assist in turning in restricted waters is good seamanship Rivers -deepest water is toward outside of the bend Ice Concentration -ice concentration is measured in tenths; what corresponds to “close pack” is 7-8 tenths. “Open Pack” is 4-6 tenths. “Very Open” is 1-3 tenths. An un-reinforced vessel can safely navigate in ice when the pack is considered “very open” at 1-3 tenths. Reinforced vessels can make it in 5-7 tenths of an ice pack. It is best to enter pack ice when the vessel has a drag of not more than 2-3 feet. To enter the ice pack, look for areas of rotten ice and enter perpendicular to the ice edge. Gradual drop in sea water, animals and a yellowish glare in the sky indicate ice may be nearby as well as white glare on clouds on the horizon. Icebergs do not indicate the presence of pack ice. Ice Blink is the yellowish-white glare on underside of cloud from ice pack. Icebergs may travel in a direction many degrees different from the sea ice. Multi-year ice has a bluish tone to its undersurface. Growlers are dangerous. Bergy Bit forms of land origin. Whiteout- snow has obliterated surface features, no shadows or horizon. Expect the lack of ability to estimate distance. But don't expect to see extensive snowfall in polar regions! Solas - according to SOLAS stability information required to be available to the master shall include instructions for the operation of cross flooding arrangments Flow State - the saturation of a dry bulk product with a liquid to the point where it behaves as a liquid Tare Weight - weight of an empty container Dew Point- when the dew point outside cargo hold is higher than the air inside, don’t ventilate. The opposite is true when the interior hold air has a higher dew point than exterior, you can ventilate. Moisture Equilibrium Chart- can be used to determine the dew point temperature that the air surrounding a hygroscopic commodity will have when in moisture equilibrium with that commodity. Can’t find the wet bulb temperature on the MEC. Special Cargo- is cargo that is of high value or easily pilferable Overcarriage- best prevented by inspection of the hold at completion of discharge Bale/Grain Cubic- the internal volume of a cargo hold, Deadweight cargo- has a stowage factor below 40 Measurement Cargo- has stowage factor above 40 Tainting- damage caused to cargos by fumes or vapors from liquids solids or gases. Cavitation- voids formed on trailing and leading edges of propeller blades causing loss of propulsion efficiency, pitting of blades and vibration. Gross Tonnage- dividing the total volume of the ship in cubic feet by 100 (after omission of exempted spaces) Net Tonnage- spaces deducted from gross are generally not used for cargo storage, and are spaces exclusive use of crew, the botswains stores List Man- wouldnt see 1 amber light Maximum Safe Docking Speed-.2 feet per second Anchoring- 1.5x the depth when using offshore anchor to dock. Squat- The basic principle of squat is the decrease of pressure on the hull resulting from increased speed. when a large vessel enters shallow water at high speeds the bow will squat farther than the stern. Turning diameter increases too. Rate of turn does not change though. The speed of the vessel thru the water has the greatest effect on squat in shallow water. Squat calculation is the square of the speed through the water. Turning using fixed object- when a buoy’s bearing relative to ship drifts aft while turning, decrease the turn rate. If the buoy drifts forward, increase turn rate. Shallow Water- considered water depth of less than 1.5x the ships draft Pitching Period- the time required to incline from bow down to stern down and return to bow down again Advance-gained direction of the original course, distance a vessel moves parallel to the original course from the point where the rudder is put over Transfer- distance gained at right angles of original course Kick- throw of a vessel’s stern from her line of advance upon putting the helm hard over Head Reach- distance the vessel will run between taking action to stop her and being stationary in the water Tactical Diameter- distance a vessel moves at right angles to the original course when 180 degrees has been completed Turning Circle- path followed by the center of gravity Pivot Points- ¼ way forward of stern when backing. ⅓ aft from bow when coming ahead. When deploying the anchor underfoot it will shift the pivot point more forward. Sidewise Force- the force exerted by a propeller which tends to throw the stern right or left. Caused by the torque from the velocity and angle at which the surrounding water impinges upon the propeller blades. Balanced Spade Rudder- loses effectiveness at angles of 10 or more degrees Wake Fraction- the ratio of the wake speed to the ship’s speed. Wake will travel in a fore/aft motion, but also upward and inward flow. Wake Current- stream of water immediately surrounding a moving vessel’s hull flowing in the same direction as the vessel Slipstream- the propeller gives a helical motion National Cargo Bureau- before any vessel that carries grain in bulk can sail they must obtain a certificate from the NCB. They certify that all preparations have been made and all regulations observed prior to loading a cargo of bulk grain. NCB can also inspect vessel for the suitability of loading hazardous materials. They represent the shipper, agent and operator. Maneuvering Characteristics- must be placed in the pilothouse of vessel ABS- could conduct survey of the insulation in a reefer compartment prior to loading. Also issue the Load Line Certificate. If you pass inspection, your current/expired load line certificate can be extended for 150 days. The annual survey of the LLC must be held within 3 months either way of the anniversary date of certificate. ABS is a classification society. Cargo ship safety construction- verifies that a liquefied gas tanker complies with the requirements with regard to their structure, equipment, fittings, arrangements and materials. IMO- requires minimum standards for initial metacentric height for cargo and passenger vessels at not less than.15m USCG- approves stability and trim booklet Change in gross/net tonnage- if the triangle downwards on top of a staggered line is submerged Dual Tonnage- a single deck vessel may not be assigned dual tonnages Load Line - primary purpose of load line is to establish required freeboard. line thru plimsol must be in line with upper edge of summer line. The difference between the top of Fresh water load line and the top of summer line, is your fresh water allowance (FWA). The load line mark is the max draft a vessel can be legally submerged. Plimsoll mark is to determine vessels freeboard. The certificate of freeboard is the Load Line Certificate and is ISSUED by a classification society approved by the USCG such as ABS. Winter North Atlantic line only applies to vessels not exceeding 328’ navigating in the winter N.A. Zones. Keeping the draft at or below the load line mark will insure that the vessel has reserve buoyancy. Regulations issued by USCG. Strictest load line regulations apply to passenger vessels. Periodic surveys to renew load line assignment shall not exceed 5 years. Load line certificate is also the certificate of freeboard Oil Record Book- any internal transfer of oil cargo during a voyage, loading/unloading of any oil cargo and or discharge overboard in port or at sea of any bilge water accumulated in machinery spaces IOPP- certificates are required for each US oil tanker at or above 150 grt Muster List- solas vessels include duties assigned to include the person responsible for the muster of passengers Convention Certificates- certificates such as cargo ship safety construction cert, ship safety equipment cert, safety management cert, ship safety radio cert; all valid for a period of not more than 60 months; 46 cfr 91.60-40. Issued by coast guard-safety equipment certificate. The safety equipment cert shows that the vessel conforms to the standards of SOLAS convention. Exemption Certificate- due to the nature of a vessel’s construction for a particular trade, it cant fully comply with the provisions of SOLAS and will be indicated on the Exemption Certificate. Also found in 46 cfr 91.60 Common Carrier- type of carrier who accepts without discrimination all legal cargoes of a shipper, required to file a copy of freight tariffs Bareboat charter Party- company agrees to pay all expenses, charter the ship, and pay for crew Demurrage- payment of penalty for a ship’s delay after the expiration of lay days due to some fault of the charterer or his agent Voyage Charter Party- contract of affreightment covering the movement of a particular cargo from one designated port to another at a specified rate for each ton of goods loaded. Charterer assumes no responsibility for the operation of the vessel, but pays for expenses such as stevedoring Notice of Readiness- when a vessel is ready to load cargo, the master should render this notice.
