Pressure-Tolerant Battery
Development Underway

In October 2015, a consortium of U.K. companies, led by Steatite, secured funding from the U.K.’s innovation agency (Innovate UK) to research and develop a battery pack that would be pressure tolerant to oceanic depths of 6,000 m.

The project, which is due for completion in October 2017, brings together expertise from lithium sulfur (Li-S) cell manufacturer Oxis Energy Ltd., underwater vehicle designer and manufacturer MSubs Ltd., scientific expertise from the U.K. National Oceanography Centre (NOC), and battery pack design and assembly specialist Steatite Ltd.

When complete, the increased energy density of Li-S cells used within the battery pack will bring a host of benefits to the Marine Autonomous Systems (MAS) sector, including improved safety, greater vehicle speed and operational endurance, significant launch cost savings, improvements in neutral buoyancy, and increased payload capacity as the batteries will not need to be housed within a pressure vessel.

Currently just past the quarter-way point of the program, development of the pack is ahead of schedule and continuing at pace. Phase one testing has been completed with very encouraging results. During the test process Li-S cells were repeatedly exposed to a combination of pressures and low temperatures, with performance observed at 660 Bar and 4° C. The results are promising, and with further iterations of testing and cell development the consortium remains optimistic that the project’s goals and performance expectations will be achieved. Phase two testing is now underway.

SeeByte Integrates CoPilot
With Heriot-Watt ROV

Heriot-Watt University has successfully integrated CoPilot with their Seaeye Falcon 1256, an observation-class ROV.

With assistance from Heriot-Watt University’s Ocean Systems Laboratory personnel, the SeeByte team integrated and tuned the system to operate with a Teledyne RDI Workhorse Navigator 600-KHz DVL. The work was conducted over a two-day period, including testing in Heriot-Watt University’s wave tank.

SeaRobotics Delivers
Two USVs to China

SeaRobotics Corp. has delivered two USV 4.0 bathymetric, autonomous 4-m vehicles to the Chinese market. The USVs were sold and delivered through LinkOcean Technologies Ltd., SeaRobotics’ exclusive representative in China. The units will be used by The First Institute of Oceanography in Qingdao and The Second Institute of Oceanography in Hangzhou to perform bathymetric surveys.

These recent orders leverage SeaRobotics extensive expertise and history delivering USVs for high-precision bathymetry, water quality analysis and hydrographic survey, as well as mine countermeasures, surveillance, targeting and many other applications. The vehicles were delivered with fully integrated R2Sonic multibeam echosounders, motion reference units, GPS systems and sound velocity probes, with software from HYPACK.

The USVs will be used in estuaries and in the coastal zone for bathymetric survey.

Updated Encyclopedia
For Marine Tech

A new online platform for the popular Wärtsilä Encyclopedia of Marine Technology, formerly known as the Encyclopedia of Ship Technology by Wärtsilä, is being launched. The new site, www.wartsila.com/encyclopedia, is more user-friendly and has more links to relevant internal and external data than the previous platform. It also has common functionality with the existing www.wartsila.com website and better connections with social media sites, thereby enabling sharing and more convenient user interaction.

The Encyclopedia provides definitions for current terminology in the industry. It is intended to help current and future marine engineers, naval architects, and other industry specialists. It also provides valuable assistance to anyone reviewing the shipbuilding trends that are moving the industry forward.

ShipManager Software
For Vertom-Bojen

Vertom-Bojen Bereederungs GmbH & Co. KG is implementing DNV GL’s ShipManager integrated fleet management software to further improve cost efficiency, process optimization and quality of operations for 41 vessels.

ShipManager helps simplify and optimize ship management by allowing extensive fleet-wide data collection, analysis, benchmarking and decision-making support with ShipManager Analyzer.

The latest release of ShipManager includes the Safety Management Reporting module with a new and flexible user interface, increasing efficiency and optimizing processes to improve safety at sea.

Transas Installs
Ship Simulator Suite

Transas has completed the installation of Scotland’s most advanced integrated ship simulator suite in the City of Glasgow College, the country’s largest college.

The installed simulator suite includes a full mission engine room simulator and four simulator labs for studying electronic navigation systems, GMDSS, liquid cargo handling and DP operations. There are also five ship handling simulators comprising four bridges with 135° visualization and a 360° full mission ship handling simulator for advanced training and certification.

Netwave Installs VDR
For Hospital Ship

Netwave has supported Mercy Ships with a new VDR installation for the Africa Mercy, currently the largest civilian hospital ship in the world, making sure the vessel remains compliant with IMO regulations.

Mercy Ships, which provides free life-saving surgeries for people where medical care is nearly nonexistent, uses hospital ships to sail into the harbors of remote countries to perform these operations.

“After changing out the Africa Mercy’s original VDR for a Netwave VDR, the maintenance issues we had with the older-generation unit have disappeared,” said Ciaran Holden, technical superintendent for Mercy Ships. “This new unit has been dependable for us.”
