Falcon ROV Assists Costa Concordia Salvage Ops
With Costa Concordia finally in dock, Micoperi (Ravenna, Italy) reported that the Saab Seaeye (Fareham, England) Falcon ROV played a vital role in diver safety during the largest maritime salvage operation in history.

Fabio Bartolotti of Micoperi, the contractor responsible for the project, says that the Falcon worked every day of the salvage operation, spending more than 1,000 hours in the water. The ROV was sent into places too dangerous for divers, and on examination and survey missions without the need for divers. The Falcon was also employed for the scanning procedure needed to measure the distance between the legs of the support platform built below the ship for the raising of the vessel.

For salvage operations such as this, the Falcon has the advantage of being small enough to be easily manhandled into the water, yet has the thruster power to work in strong currents and the intelligent architecture to handle a range of tools, including manipulator, cutters, cameras and survey and sonar systems.

The salvage contract was won by Micoperi in partnership with Titan Salvage (Houston, Texas) for removal of the wreck in one piece, minimal risk, minimal environmental impact, protection of the local economy and tourism industry, and maximum working safety.


SAMBAT Probe to Monitor Raw Water Supplies in France
Veolia Environnement (Paris, France) is setting up a monitoring station on the Blavet River in Brittany, France. The aim is to control and analyze raw water supplies before arrival at a drinking water plant in order to detect water modification and adapt treatment.

nke Instrumentation (Hennebont, France) supplied the SAMBAT autonomous multiparameter probe for the project to continuously give information on temperature, dissolved oxygen, conductivity and organic matter through total organic carbon.


HorizonVue Integrated Into ROV for Demo
For the first time, Battelle’s (Columbus, Ohio) HorizonVue undersea camera was integrated into an ROV as part of a demo in a Quincy shipyard in Massachusetts, home of Battelle’s Bluefin Robotics.

The new camera allowed operators to see the harbor floor, a nearby hull and navigate through submerged pilings using a 360° live video feed. The instrument can operate at the ocean’s surface or down to depths of 4,500 meters, withstanding pressure of 6,575 pounds per square inch.

Intended for use by work-class ROV operators and the subsea oil and gas industries, the camera provides enhanced situational awareness in areas where keeping track of multiple objects simultaneously is critical. Current technologies rely on multiple cameras that capture images that must then be “stitched together,” or have to leave portions of the workspace out of the field of view. This multiple camera solution leaves the vehicle vulnerable to collisions, or damage to equipment, which can be costly and difficult to replace.

The HorizonVue M360 Deep greatly reduces the time, effort and expense needed to work in crowded, complex undersea environments. The cameras can be easily retrofitted on vehicles currently in use or incorporated into newly built platforms using the COTS connector of choice. It can replace multiple cameras with one device that is lighter, uses less power and has no moving parts.


Four Wärtsilä 32 Engines to Power Chinese Cutter Dredger
One of the world’s largest non self-propelled cutter dredger vessels, which is also one of the world’s largest cutter dredgers with 5,200 kilowatts of cutter power, will feature Wärtsilä (Helsinki, Finland) engines to generate power and to drive the dredging pump. The ship has been designed by the Design & Research Institute of Ship and Ocean Engineering at Shanghai Jiaotong University and is being built for Jiangsu Haihong Construction Engineering Co. (Wujin, China).

The 6500 CBM vessel will be fitted with four 12-cylinder Wärtsilä 32 engines, two of which will be used to drive the dredging pump. For this application, the 6,000-kilowatt engines will run at 775 rpm instead of the normal 750 rpm.

The Wärtsilä machinery is scheduled to be delivered in August 2015. When delivered, the vessel will operate in the South China Sea and in Middle Eastern waters.

The Wärtsilä 32 is a medium-speed engine also used for generating set applications and was developed in response to a need in the market for a new engine in the 320-millimeter cylinder bore class.


Aalesund College to Upgrade to K-Sim Navigation
Aalesund University College has become one of the first Kongsberg Maritime (Kongsberg, Norway) simulator users to migrate to the cutting-edge new simulator technology platform, K-Sim Navigation. In a contract signed in January following an open tender by the college, Kongsberg Maritime will deliver a new K-Sim Navigation aft and forward bridge configuration, which is DNV Class B compliant, with an integrated DP2 simulator.

Installation is scheduled for May 2015. The college has also signed a contract for an upgrade of all hardware of the college’s existing Kongsberg Polaris ship’s bridge simulators to K-Sim Navigation.

Launched in September 2014, K-Sim Navigation is based on a new technology platform enabling more realistic training scenarios and enhanced user benefits for both instructors and students. In addition to extensive upgrades to the simulator’s instructor facilities, K-Sim Navigation features a significantly enhanced physical engine and state-of-the-art hydrodynamic modeling, allowing vessels, objects and equipment to behave and interact as in real life. The simulation system can easily be integrated with other Kongsberg Maritime simulators to enable a comprehensive range of training scenarios.

The college has also taken out a five-year Long Term System Support Program (LTSSP) with Kongsberg Maritime, ensuring its new simulators are the first to get any new software or hardware developments.
