Seatronics Chooses
Gemini 720is

Tritech International Ltd. announced that Seatronics is the first rental company to choose its next-generation Gemini 720is multibeam imaging sonar. Additionally, the multibeam imaging sonar will be used on Predator, a portable inspection-class ROV.

The new Gemini 720is combines the benefits of high-definition imaging with long-range target detection, making it ideal for AUV and ROV platforms, including installation on pan-and-tilt units. With a new body shape and enhanced electronics, the Gemini 720is continues to offer real-time visualization and a fast update rate of 30 Hz across a 120° field of view. Familiar features such as an integrated velocity of sound (VOS) sensor and near-range focus remain, and the sonar is now integrated with Ethernet communications as standard (VDSL and dual communication units are also available).

Tritech’s standalone Gemini software package now enables operation of all Tritech multibeam Gemini imagers and the Gemini profiler from one dedicated software platform. New features include basic target tracking, (including SeeByte advanced target tracking), a distance marker tool and enhanced data recording/playback and screen capture options.


NI Accredits GE
DP STR Course

The Nautical Institute (NI) has accredited GE to conduct a dynamic positioning (DP) sea time reduction (STR) course in its modern DP training center in Houston. With this accreditation, GE’s Marine Technical Training Center has joined an exclusive list of only 13 DP schools worldwide that are accredited to provide STR courses, according to GE.

The accreditation allows trainee DP operators (DPOs) to receive credit of 30 days of DP sea time when they complete five days of intensive training in the DP simulator. Using GE’s advanced DP simulator, the company can provide the trainees with a selection of scenarios that help prepare the DPOs for a multitude of possible situations that they may encounter when engaged in DP operations.

GE’s Marine Solutions’ DP simulator received the NI’s Class A Certification in June 2015.


Four C-Worker 5
ASVs Built

ASV has completed the construction of four C-Worker 5 vehicles. These ASVs will be added to the company’s global lease pool in the second quarter of 2016.

While the C-Worker 5 can accommodate a variety of client payloads and applications, it was specifically designed as a hydrographic survey force multiplier.

The C-Worker 5 is 5 m long and can operate at 7 kt. for five days before refueling. This speed/range combination maximizes acquisition effectiveness while minimizing launch and recovery operations. As a force multiplier, it can operate concurrently alongside traditional survey vessels, dramatically increasing survey efficiency.


Okeanus Adds POS MV
To Rental Portfolio

Okeanus Science and Technology announced the addition of the POS MV Surfmaster (POS MV) by Applanix to their portfolio of positioning equipment available for rent. The POS MV brings Okeanus clients georeferencing capabilities with acute accuracy in difficult conditions.

The POS MV produces accurate altitude, heading, heave, position and velocity data of marine vessels and onboard sensors. Alongside compatibility with multibeam sonar systems, the POS MV offers georeferencing for both manned and unmanned platforms. The POS MV system provides accurate results in challenging settings for harbor mapping, seafloor mapping, dredging, wreck and salvage charting and surface mapping. A full 6°-of-freedom position and orientation is achieved through its combination of GNSS data with angular rate and acceleration data from an IMU and heading from GPS azimuth measurement system (GAMS).

The POS MV enhances with the Kongsberg M3 multibeam sonar; USV sonar applications with RTK water level; vessel-mount ADCP surveys; and vessels of opportunity, single beam and multibeam.

Okeanus’s portfolio available for rent includes metocean, water collection, geophysical, hydrographic, flotation, positioning, launch and recovery, and sediment sampling equipment.


ASL to Supply Sonar
Instruments for OOI

ASL Environmental Sciences Inc. is expected to supply the last of the Un-Cabled Bio-acoustic Sonar Instruments for the U.S. National Science Foundation-funded Ocean Observatories Initiative (OOI) Coastal and Global Scale Nodes by May 1, 2016.

Under the terms of the contract, ASL will supply 16 Acoustic Zooplankton and Fish Profiler (AZFP) instruments for the Coastal Arrays and 20 individual instruments for the Global Arrays.

The two Coastal Arrays use a single bottom-mounted instrument, while the four Global Arrays use one upward-looking and one downward-looking instrument mounted on the midwater platform of the Apex Profiler Mooring.

In 2016, the first AZFP instruments with 38, 70, 125 and 200-kHz channels will be deployed on the Global Arrays, including the Argentine Basin, Station Papa, Irminger Sea and Southern Ocean Arrays.


IMO Type Approval
For MGC R3 COMPASS

Kongsberg Maritime has received IMO Type Approval (Wheelmark) for its MGC R3 COMPASS system, which is part of the range of offerings by Kongsberg for navigation and ship control systems.

The MGC R3 COMPASS integrates Kongsberg’s already established Motion Reference Unit (MRU) platform with high-end gyro compass technology, providing a reliable and accurate solution for any navigational purposes. Acting both as a gyro compass and full INS, the system outputs heading, roll, pitch, heave and position data.

The MGC R3 COMPASS features an intuitive HMI and easy configuration tools, allowing for easy deployment. Data are distributed via Ethernet and serial lines to ensure efficient distribution to multiple users on board the vessel.
