56 Maritime Reporter & Engineering News ? MARCH 2013 ABB Turbocharging announced that its new A200-L generation of single- stage turbochargers for low-speed two- stroke engines represent a quantum leap in the technological development of turbochargers. The A200-L?s compres- sor stage has been optimized to enable signiÞ cantly more additional volume ß ow. In comparison to previous models, the A200-L has up to 30% additional volume ß ow, which to date is fully the equivalent to one size smaller in a series of turbochargers. ?Our latest technical Þ ndings from development are very promising,? said David Ruch, who has been heading up the technological development of the A200-L, ?This model represents a real departure from the past model because it?s allowing us to ensure greater volume ß ow without making the concessions on efÞ ciency that we used to have to make.? Michael Lok, General Manager Low Speed Segment, said, ?We are even look- ing at a model that potentially makes no compromises on the three key variables ? that is, efÞ ciency, pressure ratio, and volume ß ow ? used to measure perfor- mance in a turbocharger. No one?s ever been able to do that, at least as far as I know. That?s a puzzle that engineers have had to wrestle with for as long as there have been turbochargers. If we?re able to achieve that with the A200-L, we will have made a hugely important con-tribution to the turbocharging industry as a whole.?BeneÞ ts of the A200-L?s additional volume ß ow are manifold. First, the A200-L?s compacter frame makes it possible to use a smaller turbocharger on a wide range of two-stroke engines. For customers, that translates into lower weight and more space, which in turn have a positive impact on the bottom line in the form of lower service costs, a lower Þ rst cost and a lower total cost of ownership. And since less material is used to make the A200-L, the impact to the environment is also reduced. ?The savings in service costs alone amount to at least 25% in many models, and in some cases even more,? says Arie Smits, Senior General Manager Global Turbocharging Projects. The company has already sold its Þ rst commissions and is currently in produc-tion. The Þ rst turbochargers will be test- ed on engines at the beginning of May, prospectively. www.abb.com/turbocharging SAM Electronics: Control Systems for Marco Polo SAM Electronics provided a combined NACOS Platinum integrated navigation command system and MCS Platinum automated monitoring and control as-sembly for the world?s largest container vessel, CMA CGM Marco Polo. It was equipped with a NACOS Platinum navi-gation control system comprising X and S-band radars linked to three mul-tifunction Multipilot workstations and an Ecdispilot for centralized control of all main radar, Ecdis and conning opera- tions in addition to those for automatic steering, track control and voyage plan-ning. Supplementary sensors for the integrated bridge conÞ guration include AIS, VDR, GPS, doppler log and echo- sounder navaids as well as SAM Elec-tronics? new Bridge Navigational Watch Alarm System (BNWAS). The NACOS assembly is complemented by an inte-grated MCS Platinum monitoring and control system governing all main ship operating components, including 4,500 I/Os on a redundant LAN network.
