2012 / 1 - Conoship

A VERY PROSPEROUS 2012!‘Contender’creating a versatile dredger out of aset to be further improved through the use ofLNG as bunker fuel, and for which a design isunder development at Conoship as part of anational R&D project.In this edition of our re-styled Newsletter,you will find many examples of ourrenewed commitment to creativity andinnovation, as we develop new ideas andpractical solutions to help customers tapnew opportunities in today’s challengingeconomic situation.A recent case in point is the conversionof a multipurpose cargo vessel (built byBarkmeijer in 1998) into a versatile, selfunloadingTrailing Suction Hopper Dredger(TSHD), to embark on a fresh and successfulcommercial career under new owner ABEKOMarine BV. The 4500m 3 TSHD ‘Shoalway’(delivered by Intervak in 2010) demonstrateda high level of efficiency during her first yearof service under the ownership of Boskalis,leading to a new series of near-repeatvessels for this owner. The design of thenew TSHD’s is slightly modified and furtheroptimised by Conoship in cooperation withD.W. den Herder Maritiem BV.Another illustration of this creative spiritis a project to raise an existing vessel’sdeadweight by increasing the maximumallowable draught through skilfulmodifications on the main deck.Conoship’s research and developmentendeavours are being brought to bear onthe final product, as they are introduced intonew designs of vessels and new solutionsfor owners. In this context, two remarkableprojects currently at the construction stagein Conoship member shipyards are thePilot Station Vessel (PSV) class in handby Barkmeijer Shipyards, and the shallowdraughtice breaking vessel at Royal NiesternSander.Global Seatrade, the subsidiary of theUrk-based Hartman Marine Group, hasrecently commissioned MV ‘Atlantic’, thefourth example of the fleet’s award-winning,exceptionally fast series of heavy-load/projectcargo vessels. Furthermore, constructionwork has been implemented on a newgeneration of project cargo carriers of aninnovative design, developed by Conoship inclose collaboration with Global Seatrade.‘Thinking towards new opportunities’To ensure future success, shipyards andshipowners must orientate to ‘Thinkingtowards new opportunities’. At Conoship, wewould like to be a partner in your ‘thinkingprocess’, and support you in exploring newpossibilities and devising new solutions. Wehave a track record of proven, innovativedesigns, and we are continuing to innovateso that you can realise fresh opportunities inexisting or new markets.Renewal and innovation are the main themesin this Newsletter. In fact, renewal is alreadyexpressed in the revised layout and natureof the content. A similar restyling has beeneffected at our website www.conoship.com,to provide an improved medium for news,developments and Conoship project updatesfrom around the world.We hope that the information presented willbe a source of inspiration to all those whoare seeking profitable, new or alternativeopportunities, and enhanced fleet capabilitiesas regards both new designs and existingvessels.We wish you good luck in meeting thecoming challenges.Best regards,Guus van der BlesLeo van IngenThe development of the Cono-Sea-Bow(in collaboration with MARIN and DelftUniversity of Technology) and innovative,high propulsive-efficiency aft-ship hull formshave led to new designs offering a very highdeadweight-to-fuel cost ratio. An additional,associated advantage is the lower exhaustemission per ton-mile of such designs.

3200 dwt General Cargo VesselDesign description: 2100m 3 Trailing Suction Hopper DredgerVessel name: TSDH ‘Contender’Owner:ABEKO Marine BV, Beverwijk, The NetherlandsBuilder:Neptune Marine Services BV,Hardinxveld-Giesendam, The NetherlandsABEKO Marine received new requestsfor dredging and land reclamationprojects, for which the company had toexpand the fleet on the short term witha new trailing suction hopper dredger.Suitable second hand dredgers werenot available which made the companydecide for the conversion of theMV ‘Sirocco’, a general cargo vesselbuilt by Barkmeijer Shipyards, into astate-of-the-art Trailing Suction HopperDredger.The design of the conversion of thisformer 3200-tdw vessel is executedby Conoship International in closecooperation with Barkmeijer Shipyards,Royal Niestern Sander and DredgeCon.The Conoship’s activities comprised there-design of the General Arrangementof the vessel to a dredger, hullformmodifications and watertight integrity.To obtain more deadweight and toimprove vessel stability, two sponsoonswere fitted to the full midship lengthof the hull, enlarging the breadth from12.50m to 16.00m. The cargo hold isredesigned into a hopper with bottomdoors. Discharging can also take placethrough a rainbowing system on thebow or to a floating pipeline througha bow coupling. Dry sand can also bedischarged by an excavator that movesover the hopper area and transportsthe sand or gravel onto conveyor beltsalong the hopper to the shore conveyor.Desalination and drying of sand andgravel is being done on board duringthe transits from the dredging area tothe discharge port.In the forward part of the original cargohold a new engine- & pump room wasPRINCIPAL PARTICULARSLength over all87.994 mLength between p.p. 83.784 mBreadth moulded 16.004 mDepth6.004 mDraught (summer) 4.724 mDeadweight (T= 4.72) 34234 tonDredging draught 5.584 mDeadweight (T= 5.58) 44864 tonSpeed (service)104 kn4EQUIPMENT 4Main engine (total output) 9994 kW4 x thruster, each 4004 kWBow thruster2004 kWdesigned, containing the dredge pump,jet pumps and two 400 kW azimuththrusters.

‘Lady Anna’ first of a new generationof Sea-River Trader vesselsDesign description: 3700 TDW Sea–River TraderVessel name: MV ‘Lady Anna’Owner:wijnne & Barends’ cargadoors- en agentuurkantoren BV,Delfzijl, The NetherlandsBuilder:Groningen Shipyard BV, Groningen, The NetherlandsOn Friday 21st of October Groningen Shipyard successfully launchedMV ‘Lady Anna’. This vessel is the first of a series of 3700-tdw vessels forWijnne Barends.The outset of this design dates fromalmost three years ago, when WijnneBarends and Conoship Internationalstarted with the first development fora new successful generation of Sea-River vessels in a modified economicenvironment. The design is focused onhydrodynamic aspects combined withlimited installed propulsion power and aversatile hold. The generated conceptdesign turned out to be feasible andattractive and with this a basis for designwas created.Last year’s R&D projects at ConoshipInternational focused on hydrodynamicaspects and optimization of hull forms.Based on extensive Computer FluidDynamic calculations (CFD), newknowledge was gained on innovativewave-reducing bow forms and onimproving propulsive efficiency byaft body design. Optimization ofcombinations of propeller-design andhigh efficiency nozzles, integratedin optimized aft ship forms, wereshowing promising results to reducefuel consumption without sacrificingdeadweight and speed.Elaboration of the Wijnne Barends designin the contract phase has been done incollaboration with Groot Ship Design forGroningen Shipyard, where ConoshipInternational focused on the optimizationof speed–power and hull lines. Thesecombined achievements resulted inan innovative and high payload vesselwith a low fuel consumption. MV ‘LadyAnna’ will sail the coastal waters ofEurope, the Trollhättan Canal and therivers Rhine and Seine. This vessel isbelieved to have the lowest possiblefuel consumption and the highestpossible speed considering the requireddeadweight and installed engine power.The MV ‘Lady Anna’ will be followed byfive more identical vessels.PRINCIPAL PARTICULARSLength over all 88.00 mLength between p.p. 84.98 mBreadth moulded 13.35 mDepth 7.05 mDraught (river) 3.40 mDeadweight (river) 2070 tonDraught (design) 4.30 mDeadweight (design) 3000 tonDraught (scantling) 4.90 mDeadweight (scantling) 3700 tonGross tonnage 2570Speed (service) 10 knEQUIPMENTMain engine 749 kWBow thruster 265 kWHOLD PARTICULARSHold dim. 62.30 x 10.80 x 7.73 mCargo hold capacity 181000 cb.ft.Tank top load 15 t/m 2CAPACITIESGasoil 90 m 3Potable water 35 m 3Ballast water 1950 m 3Draught increaseimprovements for existing shipsThe current economical situation puts a vast pressure on shipowners. Charterrates have been decreased significantly and the value of existing vessels isheavily under pressure. Moreover, stringent environmental rules and regulationsconfine the ‘playing field’ for transportation at sea.In general, today’s shipping marketbenefits from vessels with a low fuelconsumption and a high deadweight.For the long term, this means new andsophisticated development strategies fornew vessel designs. For the short term,improvement of existing vessels could bean opportunity, for example by increasingdeadweight. Conoship is involved in anumber of projects on lengthening ordeepening of existing vessels. In somecases deadweight can be increased byminor adjustments. Modification of highhatch-coamings, fitting an additionalstringer and a walkway alongside thetopside of the coaming, may lead to areduction in required freeboard. Thefeasibility of an increased draught andcorresponding deadweight increaseis amongst others depending on newfreeboard calculations, checking andre-submitting of all stability files at theincreased draught (intact and damage)and a check of constructional aspects byclass.We do not pretend that ‘draught increase’gives the solution for today’s criticalcircumstances, but it may alleviate thecurrent pressure by gaining maximumpossible deadweight. The deepeningof vessels is subject to several navalarchitectural aspects and must bechecked carefully. Please feel free toask for a quotation for an initial feasibilitycheck of draught increase of your vessel.

‘Marietje Deborah’ a new ‘high deadweight /low fuel’ multi-purpose vesselDesign description: 8300 TDW Multi Purpose VesselVessel name: MV ‘Marietje Deborah’Owner:Rederij Danser van Gent, Delfzijl, The NetherlandsBuilder:Barkmeijer Stroobos BV, Stroobos, The NetherlandsAfter successful sea trials in July, the MV ‘Marietje Deborah’ was delivered toher owners, the Dutch shipping company Danser van Gent. She is the thirdvessel in a series of four dry-cargo vessels built by Barkmeijer Shipyards.The design of the ship is the resultof joint efforts of the Danser family,Wagenborg Shipping, BarkmeijerShipyards and Conoship International.The vessel will primarily operate in theBaltic Region and the Great Lakes andis consequently designed for sailing inheavy ice conditions (Finnish-Swedish1A). She is also designed and equippedfor navigation on the Great Lakes andthe St. Lawrence Seaway.The hull form is characterized byslender lines at the waterline leveland a flaired bow section. The form isoptimized with CFD-calculations with afocus on best open water performance.Consideration of performance in iceconditions was the second step.Optimization of aft ship hull lines incombination with a high efficiencynozzle resulted in both a good speedwith relative low fuel consumption inopen water and a good performance inice.MV ´Marietje Deborah´ is following thefirst two vessels in the series:MV ´Marietje Andrea´ and MV ´MarietjeMarsilla´.

‘Atlantic’ delivered: Series of awardedHartman Trader 18 completedDesign description: 3650 TDW Heavy Lift Vessel.Vessel name: MV ‘Atlantic’Owner:Global Seatrade BV, Urk, The NetherlandsBuilder:Hartman Marine Shipbuilding BV, Urk, The NetherlandsWith the delivery of the MV ’Atlantic’ to Global Seatrade the last vessel out ofa series of four came into service in November 2011. Her predecessors out ofthis Hartman Trader 18 series are MV ’s ‘Deo Volente’, ‘Eendracht’ and ‘PacificDawn’ respectively. This prestigious design is the result of joint efforts ofHartman Marine and Conoship International and has been awarded with the“Schip van het jaar prijs” (Ship of the year award) in 2007.The sister vessels already havesound track records and the resultsprove that this versatile design withhigh autonomy and flexibility has ahigh earning capacity, even in today’smarkets. Amongst others, two maindesign characteristics contributed tothis unique position.The first is a slender hullform whichguarantees a high service speed of18 knots with a low fuel consumption.The other striking feature is her bigcargo load and discharge flexibility.Two heavy cargo cranes enable thevessel to handle cargo elements up to240 tons autonomously.For MV ’Atlantic’ the gained experiencewith the sister vessels resulted in afurther optimized design. Additionalenlargement of cargo deck space iscreated by a reinforced deck at the levelof the top of the hatchcovers at portsideas well as in the forward region of thevessel. Also a stern thruster is installedto improve vessel’s manoeuvrability.PRINCIPAL PARTICULARSLength over all 115.20 mLength between p.p. 98.20 mBreadth moulded 15.60 mDepth 7.40 mDraught 5.81 mDeadweight 3650 tonGross tonnage 2999Main engine 3680 kWSpeed (service) 18 knHOLD PARTICULARSHold dimensionsUpper Hold 63.50 x 11.50 x 8.17 mLower Hold 31.50 x 11.00 x 3.50 mCargo hold capacity 155265 cb.ft.Gearing 2x120mt at 16 mTank top load 15 t/m 2Container capacity (total) 236 TEUCAPACITIESHFO 408 m 3Gasoil 85 m 3Ballast water 2533 m 3Recent delivery‘Ennio Marnix’Design description: Bijlsma Trader 4500Vessel name: MV ‘Ennio Marnix’Owner:Scheepvaartbedrijf G. de Jonge,Emmercompascuum, The NetherlandsBuilder:Veka Bijlsma BV, Lemmer, The NetherlandsPRINCIPAL PARTICULARSLength over all 89.95 mLength between p.p. 84.98 mBreadth moulded 14.40 mDepth 7.35 mDraught 5.83 mDeadweight 4530 tonGross tonnage 2999Speed (service) 12.5 knMain engine 1860 kWCAPACITIESHold dim. 63.00 X 11.70 x 8.40 mCargo hold capacity 214000 cb.ft.Tank top load 15 t/m 2HFO 430 m 3Ballast water 1800 m 3

MV ‘Lady Helene’ was delivered by Chineseshipbuilder Wenling Hexing mid April 2011, three months later followedby sister vessel ‘Lady Hester’. These vessels are a lengthened version ofthe previous delivered 3500 tdw-series. Reference is made to ConoshipNewsletter 2009/2, MV ‘Banier’.A strong focus during the design ofthe hullform of these vessels is theoperability and performance in BalticSea and White Sea regions. Besidesextensive CFD-calculations, modeltests in ice were executed. The tests inice conditions were completed with anicebreaker close tow simulation.During operations in the frozen Balticarea in the winter of 2010/2011, thedesign proved her capabilities in iceconditions. The vessel maintainedsignificant more speed in ice comparedwith vessels of same tonnage and iceclass.CAPACITIESHFO 220 m 3Gasoil 47 m 3Potable water 38 m 3Ballast water 1850 m 3Pilot Station Vessel ‘Polaris’ succesfully launchedDesign description: Pilot Station VesselVessel name: MV ‘Polaris’Owner:Dutch Pilot Organization,Hoek van Holland, The NetherlandsBuilder:Barkmeijer Stroobos BV, Stroobos,The NetherlandsOn 18th November 2011 Conoship’smember shipyard Barkmeijersuccessfully launched theMV ‘Polaris’. This is the first ofa series of three Pilot StationVessels ordered by the Dutch PilotOrganization.This design is the result of closecooperation between the Dutch PilotOrganisation, Barkmeijer Shipyards andConoship International, supported bysea keeping and propulsion specialists.The hullform is specifically designed tomeet the operational needs of the PilotOrganization and their operational criteriaon motional behavior in harsh weatherconditions. It is optimized in view of seakeeping capabilities.
