HMS Queen Elizabeth Sets Sail with Dellner Brakes

U.K. Royal Navy aircraft carrier HMS Queen Elizabeth arrived at her home port of Portsmouth last week, fitted with two Dellner Brakes ‘stopping, turning, locking’ (STL) systems that, weighing in at 11,000 kg each, are the biggest STL systems that Dellner Brakes has ever built. Each of the carrier’s two propeller shafts is fitted with a custom-designed Dellner Brakes STL system that allows operators to stop, hold and securely lock each shaft independently, and to individually turn the shafts and giant 33 tonne propellers for maintenance and blade assembly.

US Navy: Bigger is Better, but at What Cost?

The U.S. Navy has a balanced fleet, but it wants to grow bigger and better. Will the budget allow both? Maritime Reporter's March 2017 cover story on the U.S. Navy was all about the numbers. There exists several plans to grow the fleet beyond the current number of 308 ships, the Mitre recommendation of 414 ships, the Center for Strategic and Budgetary Assessment 340-ship proposal, and the Navy’s decision to grow the fleet to 355 ships, and the Trump administration’s 350. With so many numbers being bandied about, there are even more suggestions on how to get there.

Oscar B: Power in the River Currants

Since 1925 there has been some form of car ferry crossing of the lower Columbia River from Puget Island on the Washington side to Westport Slough on the Oregon side. In 1959 Wahkiakum County took over operation of the ferry and in 1962 had a steel-hulled ferry, named for the county, built by Nichols Boat Works at Hood River Oregon. This 12-car ferry served until 2015 when the county took delivery of a larger 23-car ferry. This ferry, named Oscar B, after Oscar Bergseng who served as ferry captain for 17 years. He died in 1985 after serving further years as ferry commissioner.

US Navy 'Green Fleet' Fills up with Italian-made Biofuel

A U.S. warship took its first delivery of Italian-made biofuel on Thursday as part of the Navy's programme to use more alternative energy. The USS Mason was refuelled alongside an Italian vessel, the Andrea Doria, in the seas off of Italy's southern coast with a mix produced by Italy's Eni that has 5.5 percent palm oil biofuel blended into marine fuel. The two destroyers travelled at about 5 knots side by side with a supply ship, the Etna, between them pumping the fuel to both ships through large black tubes. "It's a first today," U.S. Navy Secretary Ray Mabus told Reuters aboard the Mason.

Maiden Voyage for China's First Self-Propelled Floating Dock

China's first self-propelled floating dock Huachuan I began its inaugural sailing recently, which opens a new era, the official People's Liberation Army Daily said. With it, large ships can be repaired at sea instead of only on the shore. It can meet repair demand of all Chinese main battle ships except aircraft carrier. The Huachuan No. 1, would enable the navy to return damaged ships to fighting capability "in very rapid time" and was designed to be sent into combat zones. "The…
