and rigging Alphatron Marine introduces Alpha-MINDS

Sperry Marine keeps shipping on the right course Northrop Grumman Sperry Marine has announced the launch of NAVIGAT 2500 and 3500, its next generation high accuracy, maintenance-free Fiber Optic Gyro (FOG) compasses. Suitable for all types of vessels, the NAVIGAT family of compasses provide superior heading measurement in all kinds of dynamic conditions with full compatibility to Sperry Marine’s networked heading management system CompassNet. NAVIGAT 2500 and NAVIGAT 3500 are based on solid-state technology with no moving parts, offering compact size and low weight. The units have rapid alignment time once installed and unlike HRG compasses whose performance in harsh environments can become degraded over time, NAVIGAT FOG compasses have no moving parts and provide a higher level of long term accuracy, especially for heading, roll/pitch, rate of turn and heave.

iXblue introduces USBL system Gaps M5 iXblue has launched the Gaps M5, a new compact, export-free and omnidirectional USBL system for accurate location, positioning and tracking of subsea assets. It is the latest addition to iXblue’s USBL product range, where it joins the popular Gaps (now Gaps M7). Gaps M5 integrates an Attitude and Heading Reference System based on iXblue FOG technology for stable heading roll and pitch compensation and a true north reference. Smaller, lighter and easy to install, Gaps M5 is ready-to-use and calibration-free. It offers an accuracy better than 0.5% up to 995m operating range, making it free of export restrictions for fast and easy shipment. With the Gaps M5, there is no need to tilt the antenna. The acoustic offers maximum aperture and allows up to 200° omnidirectional coverage. Gaps M5 is suitable for any tracking operation, from diver to multiple subsea assets, or inspection ROV-tracking while Gaps M7 remains the best asset for highest survey requirements, subsea multibeam and laser scan positioning. Third-party friendly, Gaps M5 can also be used for dynamic positioning as an acoustic transceiver using one single beacon in USBL mode or multiple beacons (3+) in LBL mode.

Intelligent adapter corrects shore power mismatches While a growing number of boats operate on 100A electrical systems, many marinas are still in the process of upgrading power pedestals to accommodate them. The YQ100PLUS adapter from Hubbell Marine offers a solution. It safely powers a 100A vessel from one or two 50A AC receptacles – especially helpful for cruisers visiting new ports. Built to last, the Hubbell YQ100PLUS adapter incorporates a rugged, UVresistant, high-impact housing that is environmentally-sealed against humidity, fog and rain. It allows a 100A 125/250V AC vessel to safely connect to single or double 50A 125/250V AC receptacles. Internal logic control automatically senses whether one or both plugs are engaged, while built-in indicator lights confirm correct phase and polarity dockside.

Jotun announces Hull Skating Solutions

Marine coatings provider Jotun has launched Hull Skating Solutions (HSS), a proactive cleaning solution for the most challenging operations. The primary component of HSS is the ground-breaking, on-board Jotun HullSkater, the first robotic technology purposely designed for proactive cleaning. As a permanent crewmember, it is always on station, ready to clean all known fouling from the hull which, if left to accumulate, causes increased drag leading to extra fuel consumption and emissions into the air (GHG and CO 2 ). In combination with the premium SeaQuantum Skate antifouling and a set of services, the Jotun Hull Skating Solutions will help ship operators combat early stages of fouling, significantly reducing fuel costs, CO 2 emissions, and the spread of invasive species. The system is designed and optimised for proactive cleaning using non-abrasive brushes to remove fouling, without damaging the anti-fouling coating. No divers are required, so the HullSkater can be used not only when the vessel is in harbour, but also at anchor.

The HullSkater removes individual bacteria and biofilm before macrofouling takes hold. This delivers both peak performance and unlimited idle days for shipowners, and minimises the need for reactive cleaning, hereby cutting costs, environmental risks, and optimising fleet flexibility. The HullSkater stays on the hull by the force of its magnetic wheels, each equipped with electric motors for propulsion and steering. The vehicle has several cameras and sensors, supporting the operator with data for navigation and documenting fouling on the ship hull. The specially designed motorised brush keeps the hull free from fouling, without causing erosion or damage to the coating. The vehicle is connected to the operator’s control centre via an umbilical and can be remotely operated for vessels anywhere in the world with 4G coverage. HullSkater can inspect a 10,000m 2 hull in approximately two hours. Inspection and proactive cleaning of a hull should take about two to eight hours, depending on size and condition. Jotun HSS provides individual proactive condition monitoring services

tailored for each vessel, using a proprietary algorithm and big data to accurately predict fouling development and cleaning schedules.

Kongsberg Maritime is responsible for the industrialisation and manufacturing of HullSkater, which will take place at a new facility located nearby its Sensors & Robotics campus in Horten, Norway. HullSkater will be supported by extended performance and service level guarantees, with global technical support from Jotun and Kongsberg Maritime.
