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.
Transas Simulation User Seminars Held in France
Transas has held a series of Simulation User Seminars in France. The events gathered more than 60 participants from maritime schools, pilot associations, navy and coast guard of the region.

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.
L-3 Maritime Systems Wins LCS Contract

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.
MAN Diesel Introduces 10 MW Engine
The new V28/33D engine has the highest power density in its class while maintaining full compliance with IMO-II and EPA Tier-II legislation. Its compact design is tailored for three main segments: multiple propulsion applications, including all types of fast ferry, naval ships, super-yachts, an STC edition; and as GenSets for offshore applications. Additional design features include the new, in-house-developed, engine-mounted SaCoSone safety and control system, and the new, TCA33 turbocharger, which has been especially tuned for the V28/33D engine as it is a light, high-efficiency turbocharger with a compact design. • an optimized crankshaft design with reduced stresses and improved lubrication an oil sump with increased volume to accommodate inclination requirement.
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.
