How to make a ship ready for shore connection

  Complying with environmental regulations and being energy efficient are key commercial differentiators in the shipping industry. Counting with these differentiators requires of having good knowledge of technology’s effects, side-effects and operational implications, explains Christian Collombet, Electrical distribution expert, Schneider Electric. Shore connection has proven to be a longer term solution when we look at the implementation, logistical, environmental and financial aspects of vessels’ operations at berth. Shore connection, enables ships to turn off their diesel engines and connect to on-shore electric power. Shore-based electricity then runs all onboard services required at berth such as safety, ventilation, air conditioning, ballast, etc. Shore Connection On-board installation Shore Connection on-board is conceived to reduce the environmental impact of ships at berth. This technology is also able to increase the energy efficiency of these mooring ships. To use power from the shore-based electricity grid, ships must be either built or retrofitted with equipment that enables the connection to shore grid, synchronizes the power changeover from shore to ship and connects the incoming power supply to the ship’s auxiliary power system. A case study: La Meridionale La Meridionale is a shipping company that manages three vessels between Marseille and the island of Corsica in ...

Port of Oakland diesel emissions way down

  Port of Oakland efforts to cut diesel emissions are producing dramatic results and gaining global recognition. That was the message from two events last week highlighting Port programs that target truck and vessel exhaust.   A University of California expert presented research showing a 76 percent drop in black carbon emission from harbor trucks. One day later, Chinese officials from Tianjin, the world’s fourth-largest port, visited Oakland to find out how it’s done. “Oakland ranks among the best in the world and we want to learn how you control pollution,” said Wen Wurui, Director General of the Tianjin Environmental Protection Bureau. UC Civil and Environmental Engineering Prof. Robert Harley said state and Port programs have modernized Oakland’s harbor truck fleet. The result: not only are black carbon emissions plummeting, but nitrogen oxides, which create ozone, are down 53 percent. Prof. Harley’s Oakland research, conducted between 2009 and 2013, was shared at a state Environmental Protection Agency webcast in Sacramento. According to the Port, its truck programs eliminated 14 tons of diesel particulate emissions between 2005 and 2012. During the same period, it eliminated another 151 tons of particulate matter from vessels. Further reductions have been achieved since ...

Port of San Diego Completes Shore Power System

Installation of a $7.1 million system The Port of San Diego is celebrating the installation of a $7.1 million system that will enable cruise ships at berth to be powered by a shore-side electrical source, which will benefit the community by reducing air pollution. With the completion of the system, the port becomes the fifth port in the world and the second in California with the capability of powering a cruise ship from shore.
