1.11 REGULATION AND GUIDANCE

TheInternationalConventionfortheSafetyofLifeatSea1974,asamended(SOLAS)ChapterII-2–Fireprotection,firedetectionandfireextinction,Regulation20,paragraph3.1.2.2states:

‘In cargo ships, ventilation fans shall normally be run continuously whenever vehicles are on board. ….’.

Theinstructionisreiteratedinparagraph8.7ofMarineGuidanceNote(MGN)341(M)Ro-RoShipsVehicleDecks–AccidentstoPersonnel,PassengerAccessandtheCarriageofMotorVehicles,whichstates:

‘…. ventilation systems serving the vehicle decks should be in operation during any loaded voyage……’

TheCodeofSafeWorkingPracticesforMerchantSeamen(COSWP)–Chapter32Ro-Ro Ferries paragraph 32.3.2 also covers the need to run ventilation fans while vehiclesareonboard.Section32.7–InspectionofVehiclesstates:

‘Before being accepted for shipment, every freight vehicle should be inspected externally by a competent and responsible person or persons to check that it is in a satisfactory condition for shipment….’

TheMaritimeandCoastguardAgency’s(MCA)publication-TheCodeofPractice–Roll-On/Roll-OffShips–StowageandSecuringofVehicles,Section1.1identifiesthat a principal source of danger to ships and persons is the unsatisfactory condition ordesignofvehiclespresentedforshipment.Section2.2states:

‘Before being accepted for shipment, every freight vehicle should be inspected externally by a responsible person or persons appointed by the ship owner, the ship manager and/or the master, to check that it is in a satisfactory condition for shipment.’

SECTION 2 – ANALYSIS

2.1 AIM

2.2 CAUSE OF THE FIRE

2.2.1 Renault Mascott-Master van

Anumberofpotentialcausesofthefirewereexamined.TheRenaultMascott-Mastervanwasconsidered.However,itsenginecylinderheadhadbeenremovedandthebatterywasdisconnected.Astherewasnoviableignitionsourceonthevan,itisnotconsideredtobetheoriginofthefire.

2.2.2 Renault Premium 250.18 truck

TheRenaultPremium250.18truckhadbeendrivenabout240kmbeforearrivingatFredericia and then onto the vessel. Neither the drivers nor stevedores reported any mechanical,electricalorinstrumentationissues.However,thetruckhadnotbeendriven for the previous 11 months and there was no evidence that any checks had beencarriedouttoproveitsroadworthinessorgeneralsafety,includingtheintegrityof its electrical and mechanical systems.

Thetruckwaslasheddownabout8hoursbeforethefirewasdiscovered.Ithadonlybeenrunforashorttimeduringloading,andthechancesofthefirestartingfromresidualheatfromtheengine,exhaustorturbo-chargerwerenegligible.

Alltheevidence,includingtheareaofhighheatenergyandtheburningandheavyradiantheatdamagetotheengineandtothefrontofthecab,indicatedthattheseatofthefirewaslocatedaroundtheupperhalfoftheengine.Theenginestartermotormainsolenoidwasseverelydamagedbyinternalarcing,whichhaddestroyedthemovingcontact.Astheenginepre-heatsolenoidwasdefective,theairchargecouldnotbepre-heatedandtheenginewouldhavebeendifficulttostart:therewasanecdotalevidencethattheenginehadtoberepeatedlycrankedovertostartit.Itisprobablethattheinternalarcinganddamagetotheenginestartermotormainsolenoid’sfixedandmovingcontactswereinitiallyduetorepeatedattemptstostarttheengine.Thiswouldhaveresultedinacontinualcurrentflowintheheavydutycablefromthebatterywhichwouldhaveremainedlivedespitetheignitionswitchbeinginthe‘stop/park’position.Overtime,continualarctrackingwithinthesolenoidwouldhavecausedfurtherdamageand,togetherwiththehighcurrentflow

2.4 RISKS OF THE CARRIAGE OF USED VEHICLES

Thecarriageofusedvehiclesandequipmentthatdonothaveappropriateroadworthinesscertificationandwhosehistoryandconditionareunknown,bringsincreased risks when compared with the carriage of well maintained vehicles that are in regular use.

2.4.1 Used vehicles – fire ignition risk

ThevehiclesroutinelyshippedonDFDSA/S’sBalticSearoutehadoftenbeenlaidupforlongperiodsduringwhichelectricalinsulationcouldbecomebrittle,componentscouldseize,andsealsonfuelandoilsystemscouldbecomeineffective,allcontributingtoanincreasedfirerisk.Electricalsystemsthathavebeenidleandarethenconnectedtochargedbatteriesareparticularlyvulnerable.Theproceduretoleavetheignitionkeyinthe‘stop/park’positiondidlittletoreducetheriskasmanycircuitsstillremainedlive.Whiletherewereotherpotentialsourcesofignition,includingengineandturbo-chargerresidualheattransfer,anddiscardedlitcigarettesandheatingequipmentleftinthecab,theprominentriskwaselectricallybased.Ifthebatteryhadbeentotallyisolated,theriskwouldhavebeenconsiderablyreduced.

Furthermore,contrarytotheMCA’sCodeofPracticetherewasnoevidencethatthevessel’s crew made any vehicle electrical system isolations or other vehicle safety checks.Indeed,itwouldbeverydifficultforcrewtosafelyisolateorremovebatteryconnections in addition to their routine tasks of loading and securing the vehicles.

2.4.3 Vessel’s safety instructions

Thevessel’sShipSafetyManagementManual(SSMM)SectionSM11-11–CargoOperations,providedgeneralinstructionsonstowing,lashing,ballastingandsafetyprecautions. Corona Seaways also held risk assessments covering lashing and unlashingcargo,ro-rocargooperations,andtheloading/unloadingofextraordinarycargo.However,neithertheSSMMnortheriskassessmentsprovidedguidanceonthespecificrisksassociatedwiththecarriageofusedvehiclesandequipment.

2.5 CREW’S FIRE-FIGHTING PRACTICE

TheOOW’sdecisiontosendtheon-watchABtocheckthestatusofthemaindeckafterthefirstfirealarmwasreasonableandappropriate.HehadnoindicationofafireontheCCTVmonitor,andheneededtoclarifythesituation.TheABalsoreasonablyoptedtocheckthemaindeckfromthedoor.HadtheABventuredbetweentheclosely-packedcargotowardstheseatofthefirehemighthavebecometrappedwhenthefirerapidlyescalated,asobservedbythemasterontheCCTV monitor.

Overall,thefire-fightingeffortwaswellconsidered,effectiveandsafelymanaged.

Inothercircumstances,thedelaycouldhavebeencritical.Manycompaniesissueallcrewmemberswithportableradiostoeasecommunicationproblems.Hadthefitterbeenequippedwitharadio,hecouldhavebeenquicklyaccountedfor.

2.7 FUNCTIONALITY OF THE LOW PRESSURE FIXED CO2 FIRE-EXTINGUISHING SYSTEM

AlthoughtherewasconfusionabouttheactualamountofCO2 discharged onto the maindeckduetotheinformationindicatedonthestoragetankcontentsgauge,thedecisionstore-injectCO2weresensiblyjudged.

On6December,theCO2systemwasservicedbyWilhemsenShipsService.Thesystemwasre-chargedandunderwentacomprehensiverangeofchecks,includingconfirmationthatthestoragetankcontentsgaugewasworkingcorrectly.However,therewasnoexplanationforwhythesystemapparentlyfailedtodischargetheallottedquantityofCO2asdesigned.ItisvitallyimportantthatthecrewhavetotalconfidenceintheCO2systemasthereisnobackupfixedfire-extinguishingsystemfor the cargo decks.

Safety precautions to be taken prior loading Car Carrier onboard the vessel 28.01.2014

Dear Customer,

DFDS A/S is committed to providing the best possible service to our customers and

to ensuring the comfort and safety of all passengers and crewmembers on board

our vessels. With that in mind, we are taking this opportunity to update all

customers using the routes in the Baltic Sea of the following mandatory safety

measures to be taken whenever second hand and/or damaged vehicles loaded on

Car Carriers are to be shipped.

To minimise the risk of fire accidents, it is your responsibility to ensure

that, apart from the previously introduced safety precautions (please refer

yourself to DFDS’ Newsletter dd. 29.04.2013), the following measures are

also to be taken prior to shipment:

- The batteries are completely disconnected - all cables

- The battery terminals are properly isolated

- The batteries have no visible damage

All Car Carriers with second hand and/or damaged vehicles will be inspected in the

port of loading and, based on the facilities available at the individual ports and on

the routes, an inspection fee will be imposed.

Any Car Carriers that do not comply with these essential requirements will not be

accepted for carriage on our vessels.

Your continuing co-operation in helping us to provide a safe travelling environment

is very much appreciated. If you have any questions, please contact your local

DFDS Seaways representative.

Sincerely yours,

DFDS A/S
