The first pressure-tolerant ROV successfully tested in the deep Atlantic. In early May 2012, a new pressure-tolerant ROV named Erno2, designed by Enitech GmbH (Rostock, Germany), was successfully tested within the framework of the “Pressure-tolerant deep-sea systems” project of Germany’s Federal Ministry of Economics and Technology (BMWi). Driven by electric thrusters, the light vehicle easily manoeuvred above the seabed, streaming live video from over 4000 m deep with its 3 video cameras and LED lights. The actual robot was attached to its tether management system (TMS) during the two-hour descent into the deep. It left the TMS 20 m above the seafloor and continued its journey being remotely controlled. A video- and data-link allowed the engineers to navigate the vehicle and monitor its behaviour. Both the TMS and the ROV were powered with batteries that can be recharged during the mission, so the ROV’s stay on the seafloor is in theory unlimited. Less than 1 m wide, the 420 kg-heavy Erno2 is a relatively small ROV. All Erno2 equipment takes up only a half of the standard 20-foot container, making Erno2 one of the world’s smallest deep sea ROVs. Operating depths of 6000 m are possible due to the vehicle’s pressure tolerant construction. To withstand the extreme pressure, all important ROV subsystems - the motor, the lights, all the sensitive electronics - are, instead of pressurized encapsulations
The Ministry of Defence awards the contract for 'Audacious', the latest Astute Class attack submarine to be built for the Royal Navy. Audacious is the fourth of 7 Astute Class submarines being built for the Royal Navy. They are the most technologically-advanced the Royal Navy has ever sent to sea and offer a step-change in capability. The contract with BAE Systems will safeguard 3,000 skilled jobs at Barrow-in-Furness in Cumbria and represents a significant step forward in the Astute
Emission-reduction technology has been successfully tested on Carnival Corporation's Holland America (HAL) ship, the Veendam. The tests were carried out jointly by Carnival Corporate Shipbuilding, HAL and RINA within a common R&D project. The technology is based on injecting water into fuel to create micro-droplets of emulsified fuel. Two pilot units were built and retrofitted on board Veendam. They were tested in accordance with an on board testing protocol developed by RINA.
HHI’s Engine & Machinery Division successfully completed a function test for a side thruster with a capacity of 2,000kW on February 12. The side thruster will be installed in a 145,000 LNG carrier for Korea Line Corporation currently being constructed at Daewoo Shipbuilding & Marine Engineering. Performance in the test was significant since it was the first side thruster built by HHI. The test was performed under the attendance of the ship owner and classification association
The three new ships are part of a Qatargas package of 45 LNG carriers with MAN B&W two-stroke prime movers Three of the world’s largest LNG-carriers successfully tested their propulsion packages at the end of last month.

As Avondale Operations valve supervisor Bubba Thornton mounted and checked the 68 valves on Polar Endeavour, he set out to improve the process of installing and testing that many valves on such a huge ship. That's why Thornton joined 20 other Avondale employees to come up with a way to test the valves prior to installation aboard ship. There is a total of 68 valves, ranging in size from 8 to 36 in. in diameter, in the Polar tanker's cargo system
