Boats evacuated one million New Yorkers after WTC attack
The Coast Guard estimates that one million New Yorkers were evacuated by boat following last week's terrorist attack on the World Trade Center.

Dozens of commercial tugs, ferries, police and fire boats, local mariners and Coast Guard boats and cutters, including the 175-foot buoy tender Katherine Walker, began a mass evacuation of people off Manhattan within minutes of the incident Sept. 11. The Coast Guard continues to provide logistical support and port vessel control through the Captain of the Port as the port begins to work toward returning to normal after reopening the financial district Monday.

Commercial vessel traffic continues to flow into the Port of New York, though additional reporting requirements and approval are required for transit through an emergency response security zone in the Hudson River below the Holland Tunnel and north of the Statue of Liberty. Passenger ferry service also resumed Monday with uniformed security personnel aboard. The port, however, remains closed to cruise ships.

An additional 41 Coast Guard law enforcement officers arrived in New York City early this morning from the Coast Guard's Ninth District, based in Cleveland, the Eighth District, based in New Orleans and the Fifth District, based here. Approximately 1,600 active duty, reserve and civilian Coast Guard men and women are now working around the clock in New York Harbor to support FEMA and New York City officials with rescue efforts and to ensure the safety and security of the port.

Thirty-eight Coast Guard cutters and boats are now on patrol and dozens of Coast Guard Auxiliary vessels, owned and operated by the Coast Guard's volunteer arm, are also on the water assisting with personnel transfers and providing back-up search and rescue support.

The Coast Guard has recalled more than 1500 reservists throughout the Atlantic Area since Sept. 11. The Commandant has received authority from the Secretary of Transportation to activate up to 8,000 members of the Coast Guard Reserve for assistance.

Coast Guard waterborne patrols have been significantly increased in the past week and additional port security measures have been put in place by the respective Coast Guard Captains of the Ports in every major port and waterway throughout the Great Lakes, East Coast, Pacific Coast, Gulf Coast and along the navigable inland rivers and waterways throughout the country.

World's first common-rail low-speed diesel engine successfully completes sea trials
Sea trials have been successfully completed with the world's first large diesel engine to have common-rail fuel injection. This Sulzer 6RT-flex58T-B low-speed diesel engine powers the 47,950 tdw self-unloading bulk carrier Gypsum Centennial, built by Hyundai Mipo Dockyard in Ulsan, Korea for the Bermudan-based owner Gypsum Transportation Ltd.

During the trials, the engine reportedly "performed exactly as expected." With full electronic control of engine functions, the engine maneuvered very easily when varying speed from full ahead to dead slow, and vice versa, and when reversing. The engine ran very steadily at very low speeds, and demonstrated its ability to run continuously at speeds down to 12 rev/min.

According to Wärtsilä Corporation, the exhaust was "effectively smokeless" throughout the sea trials, even when running on heavy fuel oil. This is because the common-rail fuel injection system maintains the fuel injection pressure at the optimum level right across the engine load range for optimum combustion under all operating conditions. In addition, a selective shut-off of single injectors at very low loads helps to keep smoke emissions below the visible limit. In contrast, engines with the traditional jerk-type injection pumps have increasing smoke emissions as engine speed is reduced because the fuel injection pressure decreases with speed.

The engine has a maximum continuous power output of 11,275 kW (15,350 bhp) at 93 rev/min. The normal service speed, however, will be 15 knots at 85 percent engine power and a sea margin of 15 percent.

Owing to the pioneering nature of this project, there is very close co-operation between Wärtsilä, Hyundai Heavy Industries Co Ltd and Hyundai Mipo Dockyard. The engine has been designed and developed by Wärtsilä. It has been built in Korea under licence by Hyundai Heavy Industries, with RT-flex parts being delivered by Wärtsilä.

Gypsum Transportation Ltd, based in Bermuda, operates a number of self-unloading bulk carriers transporting gypsum between Nova Scotia and the US East Coast. Gypsum Transportation is a subsidiary of USG Corporation, the world's largest manufacturer of gypsum wallboard, and GTL transports some 3 million tonnes of gypsum each year.
