Our Green World “Sustainable Shipping- Advanced Hull Design & Testing”

[Music][Music][Music]ocean shipping is the lifeblood of ourglobal economy but with the greening ofthe industry future shipping is likelyto be dramatically different than whatit is today especially for the nextgeneration of tankerswell shipping overall is just such ahuge industry with 50,000 ships and amillion seafarers transporting 90% ofthe world's goods it's it's a big globalindustry and while it's one of the mostefficient from a carbon emissionsstandpoint relative to othertransportation methods such as rail ortractors or airas an industry we want to constantlyevolve and have a smaller carbonfootprint new environmental legislationis underway and shipping prices continueto rise since 1999 fuel prices haverisen by over 500% and are now thegreatest cost of vessel will incur overits lifetime this means innovation andshipping is crucial for the future fuelcosts are every ship owners number-onecost for example if we were to order anew ship for 50 million dollars we wouldspend 250 million dollars or more infuel over its lifetime and so it makeseconomic sense as well as environmentalsense to try to save fuel in the lastdecade for sure we've seen much morefocus on the environment on theenvironment and I think we've also seenthe rising cost of fuel and if you putthose two together and you take intoaccount that we haven't seen anyinnovation and it seemed like theperfect time to really start thinkingabout howcould do things differently as a worldleader in shipping design TK corporationhas taken upcoming emissions legislationand high fuel costs not only as achallenge but as an opportunity to buildthe most energy efficient ship possiblethe one spirit an eco design thatreduces fuel consumption by 30% whileother shipping companies have developedeco vessels by tweaking the design ordoing simple add-ons like paint TK tooka far different approach by startingover and going right back to the drawingboard on vessel fundamentals here at itsinnovation technology and projects unitin Vancouver so it made sense to go backto look at vessel design and alter thevessel design so that we were able tominimize the total life cost of the shipso that's exactly what the the team didback in 2006 the project started off andI think it showed great foresight by theproject team because they were able tolook ahead and say well we don't believefuel price is going to come down ifanything fuel price is going to increaseso it makes sense to start to look atthis project now and for a vessel designit makes sense to go right back to wherethe rubber hits the road so to speak sowe went back and we looked at the hullform because that's where this shipinteracts with the water first is theshape of the hull so if we were able tooptimize the shape of the hull then itgives us a very very good platform tostart to look at other innovations inother ways to reduce the fuel costassociated with the shipTK then partnered with a world-renownedteam of technical experts to create thetankers ultimate design undergoingrigorous tests at its testing facilityhere at Chalmers University inGothenburg Sweden you can only take itso far through favourite oppland intabletop and we went through somecomputer development work and thecomputer development work indicated thatwe were heading in the right directionbut you can only go so far without whatyou need to do is put this into the realworld and to put it into the real worldwill cost a huge amount of money butthis facility such as this one behind uswhere it allows you to build them ascale model put it in and start to tosee how its reacting and see if you'regetting the savings that the computerindicated you were going to get andthat's what we're doing here todaybecause you have a facility here thatallows you to simulate the exact sameconditions and whether that be ahurricane or calm conditions that you'relikely to experience at sea the endresult is a tanker for the future calledone spirit which focuses on three keydesign innovations starting with theall-important hull of the ship for whichthe team ran over 40,000 simulations tofind the optimal design that reducesresistance for a given cargo capacityrun a conventional tanker this portionhere is actually quite full when thewave that comes round can dip down quitea lot which is then followed by abreaking wave what we've done here ismade this portion much more gentle sothe wave coming around the cornermanages to come back up without breakingand that contributes some 2 to 3% of thesameat the bow we have eliminated thebarbers file by basically filling thisportion II another advantage of this isthat we have a final bow entry whichmeans in a Seaway we get less addedresistance due to the waves comingtowards a hole putting this all togetherthe savings in calm water around abouteleven percent with additional savingsin a sea wave due to the reduce addedresistance in waves by narrowing thebeam of the ship and streamlining thebow and stern the design team created asleek new form that by itself resultedin over 10 percent fuel savings whilemaintaining the cargo volume of the shipby increasing the hulls length and depththe key thing about cargo carriages itall comes down to a dollar per ton ordollar per barrel freight cost and aquickest and single driver we can put into reduce the dollar per barrel freightcost is to reduce the cost of thebunkers and so the fact that this shipis more environmentally efficientsignificantly more environmentallyefficient it burns less fuel has adirect impact on the landed cost of thecargo the second innovation was adding alarger more powerful G type engine tothe tanker with increased capacity toslow the combustion process in order torecover more energy from fuel so whatwe're willing to do is we're willing topay more money for a bigger engine butthat allows us to de-rate the engine sowe're minimizing the fuel consumption sothe energy savings associated with thisare sufficient to power 2,000 homes orto power 700 cars every dayand if you expand that up into a fleetthat fleet the size of TK it's theequivalent of 42,000 cars been taken offthe road every day the bigger engine andslower shaft speed resulted in a thirdimportant innovation being able toincrease the diameter of the propellerand reduce the number of blades fromfour to three to more efficiently movemore water with each rotation the basicthing we wanted to do was to have aslarge a propeller as possible becausejust by the simple laws of physics thelarger the propeller the more effectivethe proportion so altogether we havethese three factors the improved powerassistance improved propeller efficiencyand improved engine efficiency that havefitted together into what I would callantastic ly positive this I inspire thisteam and these three design advancementshave all come together to create onespirit TK's newest green tanker and themost efficient vessel in the shippingindustry with over 30 percent fuelsavingsthis project is hydrolyzes dreamed to beapproached to do a blank machine paperdesign study and we've come up with whatwe feel is the world meetingshipping is already the most efficientform of transportation out there andwhat this ship does is it takes that andit improves itit's another 30% saving all over what isalready the most efficient form oftransport in existence and that'simportant to one spirit customers likeTK tankers with its fleet of vesselsthat transport crude oil around theworld our goal is to provide energy tothe world by being a leading providerand marine transportation and this shipthat can save 30 percent in fuel willbenefit our customers our shareholdersand the environment and so it makes justgood business sense one spirit may bethe only green vessel of its kind but itrepresents the next generation oftankers[Music]
