deployment system or via a subsea garage/docking station, which the vehicle can ‘fly’ in and out of. From the docking facilities, the vehicle can operate as an AUV (without a tether), using onboard batteries, or, where direct control is required, it can operate like an ROV either via a fiber optic tether (which enables very long excursions), or by means of a full power and control umbilical.Instead of being deployed from a dedicated support vessel, the docking station is designed to be deployed to the seabed from a vessel crane. The aim is to use a vessel already engaged at a specific location

and Pristine Seas – National Geographic Society).SEAMOR Marine's Chinook ROV has been selected for this mission given its earned reputation as a versatile vehicle that easily pairs with a variety of accessories. This particular model will be equipped with a handheld pendant controller, and a fiber optic tether multiplexer upgrade. These will help control a wide array of on-board instrumentation such as USBL underwater positioning system with GPS integration, the ROV to be tracked in real-world coordinates in real time, and an integrated Tritech Micron Echosounder which permits the ROV to measure

trials, precise movement data from Silicon Sensing’s CRH02 all-silicon gyros allowed the ADX XR to deliver a highly accurate and detailed 3- to 5-minute ship course prediction to the pilot. CRH02 is a compact, low noise, single axis gyroscope which provides outstanding performance, similar to a fiber optic gyro, but is more rugged, with a lower size and weight.ADX XR display showing the predicted turn into port (Photo: Silicon Sensing)Following this successful performance, AD Navigation placed a production order for CRH02 gyros with Silicon Sensing.Lorentz Ryan, Managing Director of AD Navigation

field comes on stream in the first quarter of 2020. Using shore power will also help to reduce maintenance, noise and vibration on the platform.NKT said it specially designed, engineered, manufactured and installed the cable order comprising the 145 kV three-core XLPE HVAC submarine cable including fiber optic links with a 55 MW capacity. Furthermore, a 3.5 km long, 17.5 kV infield cable was installed - including 500 meters of dynamic cable. The dynamic cable that connects the platform to a floating storage and offloading vessel (FSO) anchored outside the platform, was intensely engineered by NKT to

EOM Offshores Becomes SBIR Award Recipient

On February 5, 2019, EOM Offshore, LLC became a SBIR Phase I award recipient under SBIR Topic N-183-141 entitled “Technology Development of Fiber Optic Moorings for Surface Communication Buoys.”This is an exciting opportunity for EOM Offshore which plans to use its patented mooring technology to design a new lightweight, fiber optic Stretch EM Cable that will be used to tether communication gateway buoys.  To date, there is not a mooring cable on the market that can strain as the communication gateway buoy moves on the surface in wave action without the fiber optics becoming damaged

PGS Sells OptoSeis to Geospace Technologies

Norwegian marine geophysical company PGS said it has sold its OptoSeis fiber optic sensing technology business to Houston based Geospace Technologies.The transaction includes an initial cash payment at closing of $1.8 million, plus contingent cash payments of up to an additional $23.2 million over a five-and-a-half year earn-out period. Contingent payments will be derived from revenues generated from products and services utilizing the acquired fiber optic technology."After reorganizing during the fourth quarter 2017, we started exploring opportunities to divest our non-core OptoSeis technology
