Navis BGCi Sensor
Integration for CSIRO

Sea-Bird Scientific delivered a new Navis BGCi sensor integration to key customers at the Commonwealth Scientific and Industrial Research Organization (CSIRO) in Australia. The new float configuration comprises the standard Navis BGCi platform (CTD, oxygen, fluorometer/backscattering) with a SUNA Nitrate Sensor and dual OCR radiometers mounted externally.

The technology will support understanding of complex interactions between light, nutrients and microbiology in the ocean to better understand ocean productivity and carbon sequestration.


Super Mohawk II ROV
Delivered to Phoenix

Phoenix International Holdings Inc. has taken delivery of a Super Mohawk II inspection-class ROV system capable of operating up to 3,000-m depth (2,000-m standard).

Fitted with dual 1-atmosphere electronic pods, a SubCan control, protection and diagnostics system, and a camera pan and tilt unit, the Super Mohawk II is suitable for inspection, maintenance and repair; surveys; and intervention work.


Autonomous Wireless
Charging for AUVs

WiBotic announced its autonomous wireless power solutions to charge the rapidly growing ecosystem of aerial (drones), mobile (industrial) and aquatic robots. These solutions enable AUVs to stay underwater even when charging and include a wireless battery management system and fleet-level power management software.

Traditional power delivery involves mechanical contacts with a limited lifetime and high maintenance, repair and replacement costs over time. WiBotic wireless power solutions minimize maintenance costs and keep robots charged and working, which means fewer robots are needed to perform required tasks.


ASV, TerraSond Complete
Bering Sea Survey

ASV Global and TerraSond have completed a 5,172-naut. mi. hydrographic survey in the Bering Sea off Alaska. TerraSond used the C-Worker 5 ASV alongside its Q105 survey ship for 36 days. The C-Worker 5 completed 2,275 naut. mi. of survey lines, operating as a force multiplier, running parallel survey lines to the Q105. Both vessels ran multibeam sonars and simultaneously towed side scan sonars.

The C-Worker 5 was operated using ASV Global’s ASView control system from a control station on the Q105 vessel. ASView used exported survey lines from the TerraSond planning system to autonomously execute an accurate survey with minimal human intervention. Navigational safety was maintained by the C-Worker 5 operator monitoring the ASV’s color and thermal camera feeds and AIS collision avoidance system, while radar overwatch was provided by the Q105.

This 2016 deployment was a follow-on from a proof-of-concept operation carried out between TerraSond and ASV Global in August 2015 during which an ASV platform became the first to update the U.S. nautical charts for NOAA.


Big Data Supports
Shipping Operations

NAPA and FURUNO announced an ongoing partnership designed to support the digital progress of the global maritime fleet. They have integrated NAPA Performance Monitoring and NAPA Logbook software with FURUNO hardware to offer a market-ready data logging and reporting solution using data signals already present on board.

This partnership offers a simple step forward into the big data era for shipowners, operators and managers with Internet-of-things data collection, electronic logging and ship-shore and data center communications. The services offered will use existing FURUNO hardware and satellite communication solutions to support data-driven streamlining of operations.


Underwater Video for
Monitoring Tasks

Many aquaculture farms are using underwater video systems to transmit live video to the surface, allowing the aqua farmer to check the health of fish and the condition of tanks, cages and the general environment. Operators can instantly see how the population is fairing, if nets need repairing, if predators have entered, the condition of ropes and anchors, the amount of waste material present and other important environmental factors.

JW Fishers DV-2 drop video system is an example of an aqua farm tool that has a high-resolution color camera mounted in rugged, corrosion-proof housing equipped with two high-intensity LED lights. The camera is lowered from a topside vessel or platform and continuously transmits live video that can be displayed on a TV, video monitor, computer or Fishers VRM-1, which has a built-in ultrabright LCD monitor and digital video recorder. Companies using JW Fishers video technology for aquaculture include Grieg Seafarms in Newfoundland, Canada.

JW Fishers’ video technology is also effective for environmental monitoring and marine research in general.


Operational Success for
Shaft Generator

WE Tech Solutions and The Switch announced the operational success at sea of their first direct-drive permanent magnet shaft generator solution.

The first in a line of four Terntank Rederi AS chemical/product tankers destined for the Baltic Sea uses this environmentally friendly technology that enables the shipowner to cut emissions to a new level.


DNV GL Publishes
Cybersecurity RP

DNV GL has published a recommended practice (RP) on “Cyber Security Resilience Management” (www.dnvgl.com/rpcs) to help the industry address potential cyber hazards. The RP provides guidance on risk assessment, general improvements to cybersecurity and the verification of security improvements and management systems.

With ships and mobile offshore units becoming increasingly reliant on software-dependent systems, cybersecurity is an important operational and safety issue. The RP covers common threats to maritime assets, such as vulnerabilities in ECDIS, the manipulation of AIS tracking data, and jamming and spoofing of GPS and other satellite-based tracking systems
