Korean Car Carrier Puts ‘Garage Roof’ to Productive Use

STX Pan Ocean recently installed a photo-voltaic power generation system on its ocean-going 60,396 gt car carrier STX Dove, the first such system to be fitted to a Korean vessel. The photovoltaic power generation modules installed on the STX Dove, each 25 m wide and 11 m long, can generate a maximum of 24 kW from a total of 240 heat collection plates. The modules provide 5% of the electric power required for the operation of the ship including that for the engine control system, the air handling unit, lighting system, etc.

Through the modification of the module, STX plans to increase the output up to 60 kW this year and 120 kW in 2013. The company expects that it can ultimately provide approximately 30% of the power necessary for the operation of the ship by making use of solar energy, and in so doing decrease CO2 emissions as well as make a discernible saving in the bunker fuel bill.

STX say that group in-house expertise exclusively provided the material and know-how to install this shipboard photo-voltaic power generation system successfully: STX Solar developed the power generation system while STX Marine Service installed the system and provided technical consulting services.

Merchant Ships Tap in to Solar Energy

Of all ships, the specialised car carrier, with its high freeboard and relatively uncluttered ‘garage roof’ weather deck allows for substantial arrays of solar panels to be easily installed out of harm's way, and is best suited to capitalise on the sun’s free energy; features earlier recognised by Japanese interests.

Nippon Yusen and Nippon Oil developed the Toyota car carrier Auriga Leader, also over 60,000 gt, three years ago to gather operational information on the use of solar power. After some six months it was reported that solar power capabilities produced as anticipated 0.05% of the ship's propulsion power and 1% of its electrical usage which would result in lowering the ship's annual fuel usage by approximately 13 tons and its CO2 output by 40 tons.

Another Japanese car carrier of a smaller size came into service earlier this year. The Nichioh Maru, built by Shin Kurushima Dockyard for Nitto Kaiun Corporation, one of Nissan's main sea transport partners, also had solar panels installed at launch. Apparently the first time solar had been installed in an inter-island Japanese carrier.

Car carriers are not alone in fitting photo-voltaic solar modules in large ships these days by any means, even passenger cruise liners test the waters.  Environmentally aware Celebrity Cruises claimed a first when they installed solar panels on their Celebrity Solstice fitting a total of 216 panels, to give both shade to passengers as well as produce energy. Celebrity said 500 m2 of that Solstice-class ship's areas were covered and provided enough electricity to power the ship's guest elevators or 7,000 of the LED  light bulbs on board.

Soon there will be extensive use of thin-film PV, i.e., Aleo Solar's thin-film which operates off of infrared so that it doesn't matter if it is cloudy. The American Navy is testing use of Altairnano batteries as back up sources for their electric generators on destroyers, (the same batteries could be employed herein as well.)
