Four More Stena Vessels to get NAPA Software
NAPA (Helsinki, Finland) maritime software will be installed on four more Stena Line (Gothenburg, Sweden) vessels. Two ferries, the Stena Britannica and Stena Hollandica, and two freight vessels, the Stena Transit and Stena Transporter, will use NAPA software to monitor fuel consumption, speed, departure status and loading data, which can be transmitted from ship to shore in real time and analyzed in an onshore database.

Stena Lineís Energy Saving Programme (ESP) has existed since 2005. The company began installing NAPA for Operations software on vessels in 2007. Since the beginning of the project, Stena Line has implemented comprehensive shore-based monitoring of the eco-efficiency of 22 ships. Stenaís ESP program has recorded a total of $9 million in verified fuel savings.

The extension of this joint monitoring, verification and reporting project comes swiftly after NAPA and Stena Line were awarded the 2014 SHIPPINGInsight Award for achievements in fleet optimization and ship operating efficiency.


Waveblade Tests Successful at Underwater Centre
Commercial divers and ROV pilot technicians trialed the Waveblade at the Underwater Centre in Scotland, simulating a realistic operational environment. Waveblade, a lightweight, handheld submersible power tool, is designed to remove marine growth through vibration, without harming underlying surfaces. The tool has been developed to be used as a hand tool for divers and also as a separate tool to be fitted to the arm of an ROV.

Waveblade delivers high-frequency resonance through its oscillating head, sending multidirectional vibration through the blade into the unwanted marine growth. The wave power has been shown to remove organic growth more thoroughly in a fraction of time without damaging surfaces compared to current methods such as scrapers and high-pressure water jetting.


MARAD Tests Fuel Cells for Auxiliary Power
The Maritime Administration (MARAD) is testing state-of-the-art, environmentally efficient technology on board the training ship (TS) Kennedy. The National Defense Reserve Fleet vessel was provided to the Massachusetts Maritime Academy by MARAD for cadet training.

This one-year undertaking is part of a MARAD initiative to test fuel cells as a source of power for shipboard electrical systems. Researchers will evaluate the performance of the fuel cell technology and how low-sulfur marine diesel fuel can be used to efficiently power a fuel cell to produce auxiliary power. Unlike using low-sulfur fuel in diesel-engine generators to provide electrical power, the system produces no harmful air emissions.


ORPC Completes OCGen Module Mooring Project
ORPC (Portland, Maine) has concluded its highly successful OCGen Module Mooring Project at its federally licensed Cobscook Bay, Maine, project site, proving the stability of the prototype OCGen device in reversing tidal currents and confirming the loading and performance of its tensioned mooring system.

Power generation equipment that can be located at a prescribed depth, such as the OCGen device, has the potential to access the more energy-dense current resources typically found in the upper portions of the water column.

The prototype OCGen comprises a buoyancy pod attached to a chassis with two turbines placed in the water column 35 feet below mean low water.

Project highlights included: data collection under various operating conditions over a three-month period, including device movement (pitch, yaw and roll), tidal current speed and direction, turbine rotational speed, and loading on the mooring lines; further understanding of marine hydrokinetic mooring system dynamics to improve computational models; monitoring of fisheries interactions with the device; and scour monitoring of the mooring anchors that indicated minimal changes in vertical elevation of the seabed and anchor horizontal movement.


WindSentinel Survives Storm off Portugal
AXYS Technologies Inc. (Sidney, Canada) announced the EDP Inovação (EDPi) WindSentinel floating lidar system has survived a major storm that ravaged the coast of Portugal near Viana do Castelo. Enduring gale force winds with gusts of more than 90 kilometers per hour and waves 10 meters high, the WindSentinel remained on station and fully operational, with 100 percent data availability.

A similar event occurred when Hurricane Sandy hit the WindSentinel deployed on Lake Michigan in 2012. The WindSentinel ran continuously with 100 percent data collection and performance through gusts of 107 kilometers per hour and 10-meter waves.


NATO CMRE Enhances Robots for Crisis Intervention
The NATO Centre for Maritime Research and Experimentation (CMRE) played a crucial role in enhancing autonomy and integration between unmanned surface vehicles (USVs) and unmanned aerial vehicles during trials as part of the Integrated Components for Assisted Rescue and Unmanned Search operations (ICARUS) project, funded by the European Commission. Since 2012, ICARUS has been developing advanced robotic platforms to support crisis intervention teams in detecting, locating and rescuing humans in danger in maritime and land disaster scenarios. Existing technologies have been improved to strengthen resilience, and new developments include robotic vehicles that can deploy autonomous lifesaving capsules using mission-planning software, new sensors and new data acquisition capabilities to detect and track survivors. CMRE is collaborating with INESC (Laboratory of Microgrids and Electric Vehicles, Portugal) to enhance the autonomy of robotic surface vehicles and is involved in the integration of the main USV into the ICARUS Command, Control and Interface (C2I) station for collaborative operations with aerial robots. The technologies developing during ICARUS will be tested in 2015 during exercises in Belgium and Portugal.
