stowage of all iron and steel，cargoes of pig iron，steel billets，round bars and pipes are particularly difficult to secure effectively．In the upper tween decks of many two and three deck ships the absence of hatch coamings more than a few inches high adds to the difficulty of securing pig iron and billets carried abreast the hatchways and there appears to be a greater risk of cargo shifting in these spaces than in the lower holds．The most effective way to secure these cargoes is to level them and over stow them with other suitable cargo．The over stow should have sufficient rigidity or weight to act as a positive preventative to the movement of pig iron，steel billets，bars，etc．Large quantities of uncovered pig iron or billets should not be carried in the upper-tween decks with the intention of obtaining an unduly low metacentric height since this does not eliminate the risk of cargo shifting and may endanger the ship if it does shift．Where the pig iron，steel billets，round bars and pipes are stowed in ________ of a ship，their risk of shifting is the greatest．A．the upper tween deckB．the lower tween deckC．the lower holdD．in any tween deck without hatch coamingsAThe most effective way to stow such cargoes as pig iron，steel billets，round bars and pipes is to _______．A．place them in the upper tween deckB．over stow them with sufficient rigidity or weight to act as a positive preventative to the movement C．lower the metacenter of the shipD．obtain an unduly low metacentric heightBIt will endanger the ship if the pig iron，steel billets，round bars and pipes ________．A．have no risk of shiftingB．are over stowed with other cargoes of sufficient rigidity or weightC．are stowed in lower holdD．shiftDThis passage is likely extracted from ________．A．a B/LB．GenconC．BaltimeD．a Ship Repair ContractDPassage 04With one possible exception，activity in the Dover Strait during the closing hours of 5 May 1998 was normal．It was a dark clear night，the wind was west-south-west force 5 to 6 and traffic was moving easily both ways in the traffic separation scheme．As so often happens a“rogue”ship was heading north-east on the northern edge of the south-west bound lane．It was not identified．The only additional，but by no means unusual，activity that night was a cross channel survey by the 1，774gt survey vessel STM Atria．She was traversing the channel between a position off St Margaret's Bay and the Belgian coast．She was showing the lights of a vessel restricted in her ability to manoeuvre，red white and red all round lights，and alsodisplaying an orange flashing light．Regular traffic information about her activities was broadcast by the CNIS every hour．She was making GOOD between 4 and 5 knots．The traffic separation scheme ________ in the Dover Strait．A．was not establishedB．will be establishedC．was in operationD．was removedCSTM Atria was ________．A．a“rogue”shipB．a survey vesselC．CNISD．Dover StraitBThe speed of the survey vessel is between ________ knots．A．4 and 5B．5 and 6C．6 and 7D．7 and 8AThe ship heading north-east ________．A．was in the wrong lane of the traffic separation schemeB．was carrying out survey operationsC．did not carry any cargo on boardD．was a pirate boatAPassage 05The bulk carrier，long recognized as the workhorse of the world merchant fleet，has over the years had its design refined and optimized on the basis of previous successful experience．This provided what many considered to be a relatively uncomplicated and safe structural configuration．Recently，and regrettably with loss of human lives，a series of tragic ship losses has focused the attention of the marine industry and the public on the performance and inherent safety of this ship type．Extensive research and development，principally by the major classification societies，has highlighted the possible causes of the bulk carrier losses and brought about necessary changes to the design and scantlings for new ships．For existing ships，improvements to safety are anticipated throughthe reinforcement of the aft transverse watertight bulkhead，and the double bottom structure in way，of the foremost cargo hold，the introduction of a more rigorous survey regime and greater attention to operating procedures，particularly during cargo loading and discharge，in order to avoid over stressing of the structure or mechanical damage．In this paragraph，the term“workhorse”means ________．A．the ship that performs dependably in marine industriesB．a horse that is used for labor rather than for racing or ridingC．a person who works tirelessly，especially at difficult or time-consuming tasksD．something that performs dependably under heavy or prolonged useAThe refined and optimized design of bulk carriers，considered by many people，________．A．is relatively uncomplicated and safe in their structural configurationB．is relatively complicated compared with previous structural configurationC．is relatively not safe on the basis of previous successful experienceD．will join world fleet recentlyAThe ________ is not included in the anticipated improvements to safety for existing bulkships．A．introduction of a more rigorous survey regime and greater attention to operating procedures B．introduction of necessary changes to the design and scantlingsC．reinforcement of the aft transverse watertight bulkheadD．reinforcement of the double bottom structure in wayBIt is implied that a series of tragic bulkship losses ________．A．will not be avoided even new design of their structure are introducedB．were contributed by the improvements to safety for existing shipsC．has little effect on the marine industry and the publicD．were caused by their inherent structuresDPassage 06The ship loaded with general cargo had parcels of steel pipes of 13 inch diameter stowed 6 tiers high in the aft end of the tween decks．Two lengths of 2.25 inch steel wire were laid athwartships across the top of the third tier of pipes，taken back over the top of the sixth tier on completion of stowage and tightened by bottle screws secured to the ship's framing．In very heavy weather the steel pipes broke adrift and extensive damage resulted to framing，bulkheads，air and sounding pipes，etc．The wire lashings and bottle screws were completely destroyed．The diameter of the steel pipes is ________ inches．A．not mentionedB．13C．6D．2.25BThe steel pipes were stowed in ________ ties．A．2B．3C．5D．6DThe steel pipes did not cause damage to ________．A．framingB．bulkheadsC．air and sounding pipesD．the aft end of the tween decksDThe steel pipes were lashed with ________ wires．A．2B．3C．4D．5APassage 10The hull structure within the cargo area of a bulk carrier can be considered as comprising two barriers；namely，the primary and secondary barrier．The primary barrier is formed by the single skin side shell between topside and hopper tanks，and the cross deck strips，hatch covers and coamings．A failure of the primary barrier would allow water to enter the hold space．The secondary barrier is formed by the vertically corrugated transverse watertight bulkheads and the inner bottom．A failure of the secondary barrier will permit flood water in the hold to enter the neighbouring hold space．Cracking at hatch corners will directly permit water to enter ________．A．topside tanksB．the cross deck stripsC．hopper tanksD．the primary barrierDGrab and bulldozer damage to the inner bottom will allow water to enter ________．A．the secondary barrierB．transverse watertight bulkheadsC．the primary barrierD．the topside and hopper tanks，AHatch covers are ________．A．primary barrierB．secondary barrierC．either primary barrier or secondary barrierD．neither primary barrier nor secondary barrierAIn accordance with the passage，the bridge deck should be considered as ________．A．primary barrierB．secondary barrierC．either primary barrier or secondary barrierD．neither primary barrier nor secondary barrierDPassage 11The damage scenarios applicable to single side skin bulk carriers assume initial damage to the primary barrier，formed by the shell and hatch covers，followed by the failure of the secondary barrier formed by the double bottom and the transverse bulkheads．Primary barrier failure could occur in one of two ways．The side shell could be damaged or the hatch covers could fail under the pressure from green seas on deck or be swept away，thereby allowing water to enter the hold．The most likely cause of initial side shell failure，other than collision，results from the progressive reduction of support from corroded and fractured side shell frame end bracket connections to topside tanks and hopper tanks．Corrosion of end bracket toes creates a stress concentration with the location being subjected to fatigue loading from the passage of waves along the side shell．This can lead to the growth of fatigue cracks until the end brackets are completely detached from the side shell．Similarly，weld grooving of side frames and brackets can lead to detachment．In each case，loss of secondary support will lead to loss of the side shell and water will enter the hold．According to this passage，________ will be suffered from damage first．A．primary barrierB．secondary barrierC．double bottomD．transverse bulkheadsACorrosion of ________ is not likely lead to detachment of the corresponding structural member．A．weld grooving of side frames and bracketsB．end bracket toesC．side shell frame end bracket connections to topside tanks and hopper tanksD．the shell and hatch coversDFatigue loading to end bracket toes is created by ________．A．the passage of waves along the side shellB．the side shell frame end bracket connections to topside tanks and hopper tanksC．the detachmentD．the secondary supportAIn general，loss of secondary support will ________．A．create a stress concentration with the locationB．assume initial damage to the primary barrierC．lead to loss of the side shell and water will enter the holdD．lead to the growth of fatigue cracksCPassage 14Many carriers today make use of relay ports at which GOODs destined for more remote locations are transshipped onto substituted ships or“feeder vessels”，in order to secure faster and more efficient delivery than would be possible if the cargoes concerned were carried all the way to destination aboard the liner vessels on which they were firstloaded．The transshipment of cargo at such intermediate ports has been judged not to constitute an unreasonable deviation where it is shown to be a custom of the trade．Nor，of course，is it an unreasonable deviation where the shipper acquiesced in it，had notice of it or could have expected it based on prior shipments with the same carrier，or where the carrier has made known its ordinary stops by its advertisements，publications or other means．A Relay Port means a/an_______．A．port of destinationB．port of sailingC．intermediate portD．port of refugeCCargo will be possibly delivered slower to its destination by _______．A．a feederB．a substituted shipC．the liner on which it was first loadedD．the liner on which it would be loaded should a feeder or substituted ship not be availableCUnder which of the following conditions is it not sufficient to judge that transshipment at the relay port doesnot constitute an unreasonable deviation ___________．A．the transshipment is shown to be a custom of the tradeB．the shipper had notice of the transshipmentC．the shipper could have expected it based on prior shipments with the same carrierD．the carrier has not made known its ordinary stops by its advertisements or publicationsDThe purpose of making use of a relay port by the carrier is to achieve the end of _______．A．faster and more efficient deliveryB．avoiding unreasonable deviationC．making known its ordinary transportation by its advertisements，publications or other means D．preventing the adverse influence to the carriage by a custom of the tradeAPassage 17On the bridge for the approach to the pilot boarding ground were the Master，who had the con，the Mate，as Watch Officer，and a seaman at the wheel，while the Third Mate went on deck to meet the pilot．The normal procedure onboard was for the Second Mate to prepare the voyage plan and to lay off the courses onthe charts．However，because the passage from Burnie to the Tamar River was relatively short and because he intended stopping and drifting for two to three hours，the Master decided to lay off the courses himself．In the past，when the company employed Japanese officers，the Master would discuss operational and navigational procedures with them．However，since the introduction of the employment of Filipino officers，the Master no longer did this，with the result there was no cohesive bridge team．When the pilot launch arrived alongside，the Mate went to the port bridge wing and remained there until such time as the Pilot had gained the deck．At a critical stage，when manoeuvring close to a reef，he was providing no active support to the Master by monitoring the vessel's progress，either by radar or by the electronic plotting table．With no active support from the Mate，the Master had quickly plotted the position at a time he recorded as 0606，from which he realised there was a danger of the stern swinging into the eastern shallows of Hebe Reef．In instructing the helmsman to steady on 1600，however，he does not appear to have appreciated the developing situation with West Reef，created by that action，and the vessel grounded fast in the Reef．The Master did not discuss operational and navigational procedures with his mates because _______．A．he has ethnic or cultural prejudice in his dealings with those officersB．he laid off the courses himselfC．the bridge was adequately manned for the operationD．the Second Mate did not prepare the voyage plan and lay off the courses on the chartsAOf the following _______ is not a contributing factor leading to the grounding accident．A．that Master did not inform the Mate of his intended actions or seek the Mate's support in monitoring and advising him on the progress of the manoeuvresB．that the Mate did not provide active support to the MasterC．that navigational equipment was either ignored or not used to full effectD．that the Mate went to the port bridge wing and remained thereDIt is inferred that the vessel started the voyage in _______．A．an early morningB．a late eveningC．an afternoonD．a midnightAThe main cause of this accident is the lack of _______．A．seamanship skill of the Master and the Mates on the bridgeB．Bridge Resource Management proceduresC．academic education of the crew members，including the Master and Mates D．communications between the Pilot，the Master and the Mates on board the vesselBPassage 24On 22 February 2005 the Bahamas flag bulk carrier Clipper Kawa was lying at the outer anchorage off the port of Albany，Western Australia．At about 0815，the Bosun，with the two deck cadets and two seamen set to work transferring used dunnage lying on the hatch cover of No.3 hold，to the space between the break of the forecastle and No.1 hatch．The Bosun and the two cadets went to unlash the forward gantry crane of the ship．This done，the senior cadet remained in the starboard driving cab while the Bosun，the junior cadet and the two seamen slung the dunnage．On completion，the Bosun and the two seamen alighted from the port side of the hatch cover，while the junior cadet alighted on the starboard side．The two seamen then went forward，and the Bosun，having received an“all clear” signal from the cadet on the starboard side，signaled the driver to move the gantry forward to No.1 hatch．After the gantry crane arrived at No.1 hatch and lowered the dunnage，the Bosun noticed that the junior cadet had not arrived up forward．He walked aft on the starboard side and found the cadet，apparently unconscious，lying against the hatch coaming of No.2 hold．The crew carried him into the crew's recreation room in the accommodation and the Chief Officer started to apply CPR（Cardiopulmonary resuscitation，心肺复苏）．Shortly afterwards，on unzipping the overalls of the cadet，it was found that his abdomen had burst open and it was concluded that he was．The post mortem revealed that he had died from shock and haemorrhage（大出血）following multiple crush injuries．The dead person was ________．A．one of the two seamenB．the junior cadetC．the senior cadetD．the driver of the craneBALL CLEAR was signaled by ________．A．one of the two seamenB．the BosunC．the junior cadetD．the senior cadetCThere were ________ people working on the fore deck at the time of the accident．A．4B．5C．6D．7BIt can be concluded that ________．A．Either fatigue or alcohol or both shall be considered to have been contributing factors in the death B．the person was killed by one of the crew members，such as C/O，Bosun or any other persons on board the shipC．the dead person committed suicide himself for unknown reasonsD．the person died of an accidentDPassage 25Coils should be properly secured and lashed on board ship．The objective is to form one large，immovable block of coils in the hold by lashing them together．In general，strip coils in three end rows in the top tier should be lashed．To prevent fore-and-aft shifting in the top tier of bare-wound coils group-lashing should not be applied due to their fragile nature；the end row of a top tier should be secured by dunnage and wires，which are to be tightened from side to side，and by additional wires to the bulkhead．When coils are fully loaded over the entire bottom space and are well shored，no lashings are required except for locking coils．The lashings can be of a conventional type using wire steel band or any equivalent means．Conventional lashings should consist of wires having sufficient tensile strength．The first tier should be chocked．It should be possible to re-tighten the lashings during the voyage．Wire lashings should be protected against damage from sharp edges．If there are few coils，or a single coil only，they should be adequately secured to the ship，by placing them in cradles，by wedging，or by shoring and then lashing to prevent transverse and longitudinal movement．LOCKING COIL is the coil ________．A．which is placed between two underneath coils to prevent their shiftingB．which has a few locks on or around itC．which can be locked from inside of the axe in the fore-and-aft directionD．to which wedges should be used as stoppers when necessary during loading and discharging to prevent shiftingA________ should be secured by dunnage and wires．A．the top tier of bare-wound coilsB．strip coils in three end rows in the top tierC．the first tier coilsD．the end row of a top tier coilsDCradles are usually needed for the stowage of ________．A．the end row of a top tier of coilsB．strip coils in three end rows in the top tierC．a few coils or only one coil on board the shipD．the top tier of bare-wound coilsCThis passage is probably extracted from ________．A．IMDG CodeB．BC CodeC．CSS CodeD．SOLASCPassage 31Class 4 of dangerous cargoes deals with substances，other than those classed as explosives，which，under conditions of transport，are readily combustible or may contribute to a fire or cause one．Class 4.1 cover readily combustible solids and solids which may cause fire through friction；self-reactive（solids and liquids）and related substances；and desensitized explosives．The substances in this class are solids possessing the properties of being easily ignited by external sources，such as sparks and flames，and of being readily combustible，or of being liable to cause fire through friction．Class 4.2 are substances liable to spontaneous combustion．The substances in this class are either liquids or solids which are liable to spontaneous heating under normal conditions encountered in transport，or to heating up in contact with air，and being then liable to catch fire．Class 4.3 include substances which，in contact with water，emit flammable gases．The substances in this class are either liquids or solids which，by interaction with water，are liable to become spontaneously flammable or to give off flammable gases in dangerous quantities．Liquids which are liable to spontaneous heating under normal conditions encountered in transport shall be classed into ________．A．Class 4.1B．Class 4.2C．Class 4.3D．other class than class 4BSelf-reactive liquids shall be classed into ________．A．Class 4.1B．Class 4.2C．Class 4.3D．other class than class 4A________ does not belong to Class 4.1．A．substances which，in contact with water，emit flammable gasesB．desensitized explosivesC．solids which may cause fire through frictionD．readily combustible solidsAThis paragraph is most likely extracted from ________．A．Marpol 73/78B．SOLASC．CSS CodeD．IMDG CodeDPassage 32The main part of a ship is the hull．This is the area between the main decks，the sides and the bottom．It is made up of frames covered with plating．The hull is divided up into a number of watertight compartments by decks and bulkheads．Bulkheads are vertical steel walls going across the ship and along．Decks divide the hull horizontally．Those dividing up cargo spaces are known as tween decks．The hull contains the engine room，cargo space and a number of tanks．In dry cargo ships the cargo space is divided into holds，in liquid cargo ships it is divided into tanks．At the fore end of the hull are the fore peak tanks and at the after end the after peak tanks．They are used for fresh water and water ballast．The space between the holds and the bottom of the hull contains double bottom tanks．These are used for ballast water and fuel．The bulkheads are vertical structures of ships which go ________．A．across the shipB．along the shipC．either across the ship or along the shipD．both across the ship and along the shipC________ are known as decks．A．Those structures dividing up cargo spacesB．Vertical steel walls going across the ship and alongC．The walls of engine room，cargo space and a number of tanksD．Those structures dividing the hull horizontallyD________ are used for fresh water and water ballast．A．The space between the holds and the bottom of the hullB．liquid spacesC．bottom tanksD．peak tanksDThis paragraph is most likely extracted from ________．A．Marpol 73/78B．SOLASC．Stability BookletD．Other documentsDPassage 33Failing to identify pre-shipment damage and neglecting to make appropriate notations on bills of lading will deprive the carrier of his rights，limitations and immunities under the contract of carriage and may prejudice Club cover．Assertions are sometimes made by cargo interests that rust on a particular shipment is normal and will not affect its market value．Such comments should be disregarded．In all cases where a steel cargo is found to be rusty，it is imperative that remarks are made on the bills of lading，irrespective of the apparent severity of the rust．The bills of lading should also be claused to reflect any physical pre-shipment damage to the steel and/or wrappers（bends，tears，crimps，dents，deformation，crushing）．Selecting the most appropriate clauses to describe pre-shipment damage is not always easy，and the attending surveyor should be consulted for advice．Where possible，the clausing should list the identification marks of the damaged GOODs，failing which the number of coils or packages should be quantified．Percentage estimates regarding the number of damaged pieces should not be given．If it is not possible to identify the damaged GOODs specifically，the words”some”or”several” may be acceptable．Any differences found between the ship and shore tally or ship and bill of lading figures must be noted on the bill of lading in the usual manner．The clausing on B/L is to reflect and make notation of ________ the cargoes and/or their wrappers．A．all damages incurred during the carriage by sea toB．all possible damages to and/or losses ofC．physical pre-shipment damages toD．pre-shipment damages toDThe pre-shipment rusts for which there are assertions made by cargo interests that they are normal and would not affect the cargo's market value shall ________．A．be claused on the Bill of LadingB．not be claused on the Bill of LadingC．be disregardedD．not be disregardedAThe proper topic of this paragraph is ________．A．The Principles for Clausing on Bills of LadingB．Losses of and Damages to Steel CargoesC．Legal Actions to Be Taken When Losses of and Damages to Cargoes IncurredD．The Functions of Clauses Made on Bills of LadingAThis paragraph is most likely compiled to protect the interests of ________．A．the carriersB．the shippersC．the merchantsD．the cargo ownersAPassage 34Both biotic and chemical stresses are closely interrelated both with each other and with climatic stresses．It may accordingly be assumed that biotic and chemical reactions proceed particularly well when exposed to certain temperature and moisture conditions．Biotic stresses are deemed to be present if GOODs，packaging or parts thereof are damaged by living organisms of whatever kind．Chewing damage may，however，cause considerable losses．The risk is relatively low in closed containers，provided that no animals have taken up residence before packing or“sneak in”during packing．Since many rodents are nocturnal creatures，cargo transport units which are being packed should be closed during work breaks or at the end of a shift especially during the hours of darkness．Prior inspection of cargo transport units for tightness is a basic requirement．Insects，for example，can nonetheless still get into such closed containers which，although classed as unventilated，still have openings of small cross-section．It will be virtually impossible to avoid damage if GOODs and/or packaging are infested before packing and such infestation is not noticed．In the case of “open”cargo transport units，infestation can only be prevented by providing sufficiently tight packaging or suitable preservation．Chewing damage is a kind of ________ damage．A．bioticB．climaticC．chemicalD．virtually impossibleAThe risk of biotic damage to the cargoes in closed containers ________ that in open containers．A．is lower thanB．is higher thanC．is the same asD．can hardly be told if lower or higher thanAThe purpose that cargo transport units which are being packed should be closed during work breaks or at the end of a shift is to ________．A．reduce climatic stresses when cargo working is resumedB．inspect cargo transport units for tightnessC．provide sufficiently tight packaging or suitable preservationD．avoid rodents to sneak inDIn the author's opinion，damage to cargoes by insects contained in closed containers is likely to happen ________．A．only before packingB．only during packingC．only after packingD．in the whole process of transportation by seaDPassage 36Dangerous GOODs shall be packed in GOOD quality packagings，including IBCs and large packagings，which shall be strong enough to withstand the shocks and loadings normally encountered during transport，including trans-shipment between cargo transport units and between cargo transport units and warehousesas well as any removal from a pallet or overpack．Packagings，including IBCs and large packagings，shall be constructed and closed so as to prevent any loss of contents when prepared for transport which may be caused under normal conditions of transport，by vibration，or by changes in temperature，humidity or pressure（resulting from altitude，for example）．Packagings，including IBCs and large packagings，shall be closed in accordance with the information provided by the manufacturer．No dangerous residue shall adhere to the outside of packages，IBCs and large packagings during transport．These provisions apply，as appropriate，to new，reused，reconditioned or remanufactured packagings，and to new，reused，repaired or remanufactured IBCs，and to new or reused large packagings．Parts of packagings，including IBCs and large packagings，which are in direct contact with dangerous GOODs shall not be affected or significantly weakened by those dangerous GOODs；and shall not cause a dangerous effect，such as catalysing a reaction or reacting with the dangerous GOODs．The loss of contents referred to in this passage in packagings，including IBCs and large packagings，are not caused by ________．A．vibrationB．changes in temperatureC．changes in humidity or pressureD．trans-shipment between cargo transport units and between cargo transport units and warehouses as well as any removal from a pallet or overpackDWith regard to the parts of packagings，including IBCs and large packagings，which are in direct contact with dangerous GOODs，________ is correct．A．they shall not be affected by those dangerous GOODsB．they shall not be significantly weakened by those dangerous GOODsC．they shall not catalyze a reaction or react with those dangerous GOODsD．they shall not be closed so as to prevent any loss of contents when prepared for transportDThese provisions shall not apply to ________．A．repaired or remanufactured large packagingsB．repaired or remanufactured IBCsC．new or reused IBCsD．new，reused，reconditioned or remanufactured packagingsA。
