10 Maritime Reporter & Engineering News ? NOVEMBER 2013 NEWSUASC & HHI News in BriefSeaspan: Historic Deal for 10 Non-combat ShipsSeaspan?s Vancouver Shipyards announced that it will build an additional 10 Noncombat vessels for the Canadian Coast Guard. The new ships increase Seaspan?s noncombat build package to 17 ships from the seven originally announced on October 19, 2011. These additional ships include Þ ve medium endurance multitasked vessels (MEMTVs) and Þ ve offshore patrol vessels (OPVs). Through the NSPS, Seaspan will develop and grow a world-class shipbuilding and ship repair center of excellence on the west coast that will create signiÞ -cant economic beneÞ ts for BC and Canada for de- cades to come. ?We are one year into our Shipyard Modernization Project, and with approximately one year remaining, the transformation of Vancouver Shipyards has been profound,? said Brian Carter, President - Seaspan Shipyards. ?In addition to the progress on facilities, we are making a huge invest-ment in people, processes and tools.?Aliança Christens New ContainershipWith the Américo Vespúcio, Hamburg Süd subsid- iary Aliança christened the third of four identical 3,800 TEU container ships for its cabotage ß eet on October 22, 2013 in Pecém (Brazil). The newbuild series allows Aliança to progress with the modern- ization of its ß eet. Like the Þ rst two newbuilds, the Américo Vespúcio was also built at the Shanghai Shipyard Co., Ltd. and was delivered on August 23, 2013. After completion of import formalities the ship was loaded with the Þ rst containers for the Aliança cabotage service on October 14, in Manaus. In the quest for large containerhip ef Þ ciency, United Arab Shipping Co. turns to HHI & FutureShip United Arab Shipping Company (UASC) will expand its ß eet with new ef Þ cient container vessels. Built to DNV class, the designs have been optimized through a cooperation between FutureShip and Hyundai Heavy Industry (HHI). Setting its sights on competitive slot cost, UASC, one of the world?s fastest growing con- tainer carriers, has ordered Þ ve 14,000TEU vessels with six options and Þ ve 18,000TEU vessels with one option.Like the rest of the marine world, minimizing fuel consumption and emissions loomed large in the deci- sion to order, and UASC partnered with FutureShip with the aim to realize an efÞ cient design. Four sets of designs were shortlisted for intensive evaluation by FutureShip with numerical tank towing tests based on Computational Fluid Dynamics (CFD) simulations for the ship with propeller. In four weeks, FutureShip ran thousands of tests to determine the speed-power relationship for the two ship classes at two drafts for each of the four competing designs, add-ing up to some 1.7 million CPU hours, or 200 CPU years. The use of massively parallel computation al- lowed multiple tests to be run at the same time, over speed and draft ranges which reß ected realistic opera- tional proÞ les.The four designs were all well matched, with HHI?s design emerging as the winner due to a 14,000TEU vessel design that outperformed the competition and the most efÞ cient (single-skeg) vessel design at 18,000TEU. A formal parametric optimization was also conducted to Þ ne-tune vessel performance for UASC?s operating pro Þ le in the intended service pat- tern of the ships.For Þ nal validation, professional model tests were conducted at the Hamburg Ship Model Basin. The model tests backed up FutureShip?s CFD predictions, supporting the accuracy of the optimization results. To realize further ef Þ ciency gains on the operational side, UASC decided to implement FutureShip?s ?ECO- Assistant? trim solution. Backed up with a comprehen-sive database of possible operational conditions evalu-ated by CFD analysis, this tool provides an intuitive interface to select the most efÞ cient trim for every voy- age.(Photo: USAC)L to R: Norbert Bergmann, Andre Magalhaes, Julian Thomas, Ivens Dias Branco, Consuelo Dias Branco, Frank Smet, Martin Susemihl, Capt.Carlos Camara und Matthias Dietrich.MR #11 (10-17).indd 10MR #11 (10-17).indd 1011/12/2013 10:30:38 AM11/12/2013 10:30:38 AM
