GE Propels the US Navy with Increased Resilience

Approximately 80,000 tons (fully loaded) and 784 feet in length, with a beam of 164 feet—more than a third wider than most ships—Expeditionary Base Mobile (ESB) 4 is an extremely stable platform for sea base operations. Enabled by GE’s electric power and propulsion system, and built by General Dynamics, National Steel and Shipbuilding Company (NASSCO), ESB 4 will be able to operate at a speed of 15 knots with an endurance of over 9,500 nautical miles. ESB 4 is the second ship of this type to be outfitted as an Expeditionary Base Mobile, formerly called the Afloat Forward Staging Base. It will be able to accommodate up to 250 personnel. The new 784-foot vessel will feature a 52,000-square-foot flight deck, fuel and equipment storage, repair spaces, magazines and mission planning.

Alion’s MOTISS – IBA: the Science of Survivability

An Improved Risk and Safety Assessment Process for the offshore oil & gas industry – and just in time. Alion’s Measure of Total Integrated System Survivability (MOTISS) has been around a long time. Having previously earned its stripes primarily for naval applications, Alion began to market the service to the offshore oil & gas industry in the messy wake of the Macondo disaster. That event brought to the forefront, more than ever, the need to prepare for similar occurrences in the future and more importantly, increase industry’s ability to conduct analysis.

Participants at a workshop exploring the use of titanium structure for ships found that it is not only possible to construct a ship hull from titanium—or Ti, it could be cost effective. The workshop was sponsored by the Office of Naval Research and hosted by the University of New Orleans, where an ONR research program on titanium ship structures is being conducted. Representatives of the shipbuilding industry, titanium suppliers, Navy, Coast Guard and Air Force labs, and academia discussed and examined materials, processes and applications. Most ships today are primarily made from steel.

Meet the Wider 42 - Commercial

A planning boat that is light, fast and economical, yet has the usable deck area of a boat twice it’s size and the stability of a trimaran! Sounds too good to be true, well that was my initial reaction until I attended the Press launch in Italy of the “transformer” Wider 42. I call it transformer because that’s what it does. It can plane at speeds over 50 knots and when it stops, by pressing a button, in 12 secs it transforms the cockpit deck into an are twice its size. To ensure stability, two sponsons, one each side slide out from the hull to increase stability.

Becker: New Composite Rudder Flap and Stock

Becker is continuously developing propulsion components with new or better properties. One of Becker's approaches - along with Bureau Veritas - is the use of new materials such as carbon composites. Carbon fiber provides two main advantages: On the one hand, weight savings of more than 50 percent enable easier handling during transport and assembly, making this suitable for advanced naval applications focusing on light-weight structures. On the other hand, a reduction of raw material waste of 60 percent compared to forged steel helps achieve a lower carbon footprint.

MTU Series 8000 Demonstrates Power

Since its introduction in 2000, MTU's Series 8000 high-speed diesel engine has gained popularity among Naval and Commercial shipbuilders because of its performance and operating availability. With over one hundred 20V 8000 engines sold, and with over 160,000 hours in combined operation, the world's highest power to weight ratio in this power range is said to be the low risk propulsion engine option for many navies and high-speed ferry operators. Delivering up to 12,200 bhp (9100 kW) of continuous power, MTU's Series 8000 has consistently set the performance benchmarks for fuel efficiency - less than 190g/kWh, while achieving IMO Marpol NOx emission certification. The 20V 8000 engine is now also available in a US EPA Tier II emission certified configuration.
