Metal Shark Debuts Prowler Autonomous Vessel and Frenzy Micro-USV
. Prowler’s system architecture provides the forward flexibility to accommodate third party software and/or hardware upgrades to support collaborative intercept capability or other technologies as they may be required.Prowler’s computer system, along with propulsion, mechanical and electrical systems are contained within a single removable module to allow for expedited onsite servicing, repair, upgrade or replacement with no need to transport the vessel.Prowler can simultaneously carry multiple payloads, with 1,000 lbs. of total payload carrying capacity. In addition to the aforementioned

maneuverability offered by remotely operated vehicles (ROV), such as SEAMOR Marine’s Chinook ROV, has always held a great deal of promise to subsea engineers designing magnetometer scanning systems. However, technicians have been challenged by the electro-magnetic interference created by the electrical systems of these smaller units; that is, until recently.Earlier this year, SEAMOR Marine was contracted at the request of a private client through Ocean Floor Geophysics for a third party integration of their magnetometer with the Chinook ROV. “SEAMOR’s Chinook is compact, maneuverable

did previously, reaching the seafloor at a depth of 7,960 meters.Parisi's role was to ensure smooth operations of the system's hardware, while Roman managed the software side."I would test the communications with acoustic releases, rig up drop weights, arm Niskin bottles, and power the electrical systems on and off," said Parisi, who is from Naperville, Illinois. "We also added a downward-facing camera and bait to record deep-sea life in action. I reviewed the footage and passed it on to interested researchers on board. There were hundreds of amphipods, a handful of decapods, one

cable’s dynamic behavior. Understanding how our TLP mooring system reduces motions and loads on the cable, compared to catenary systems, is crucial as it will reduce fatigue and potentially extend the lifetime of this critical component.“Our X30 platform is fully equipped with all the electrical systems that our commercial platforms will incorporate. The Vestas V29 turbine, originally designed for fixed foundations, has been retrofitted using a full-converter supplied by ABB and the control has been optimized to floating conditions. The voltage is increased to 20kV with a transformer, to allow

phase to evaluate noise sources and devise means to mitigate. “Nothing makes direct contact with the hull; to sonars,” said Mauricio. In addition, Vigor partnered with Bruce S. Rosenblatt & Associates (BSR) to provide detailed engineering support of structural, mechanical and electrical systems. BSR used 3D modeling to develop detailed production level drawings suitable for material procurement and shop prefabrication. The 3D modeling process also helped identify design issues such as equipment and piping system clashes early in the design phase. Engine room removal access.

carbon neutral by 2050,” explains Søren Toft, Maersk COO.Propelling marine vessels with battery power alone is still years away from being a technically- and economically viable option. However marine battery systems can be used to improve the efficiency of a vessel’s onboard electrical systems such as the Maersk Cape Town’s generators. By maintaining the vessel’s auxiliary generators at a more optimal load, and avoiding running generators when not needed, overall fuel consumption can be reduced.Additionally, it will support the generators with up to 1,800 kVA of power

The T-class type certification for the Rotor Nacelle Assembly will be achieved by December 2020, where the product will be certified to handle extreme wind speeds in hurricane conditions in accordance with IEC 61400-1 edition 4. Furthermore, electrical systems and components will be adapted to 60Hz operation
