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

a rotating connection for low voltage power, electrical signal and optical cables in a single package. The shaft is configured with hanging turret side cable pigtails that are factory installed.This model is designed to be located at the top of a swivel stack to allow functionality of a multichannel fiber optic rotary joint. The swivel is certified as a flameproof enclosure with increased safety junction boxes on the ship’s side. It is approximately 2.8 m high with a diameter of approximately 0.7 m and weighs approximately 1 ton

.3-kilopascal, when dry or 0.43 kilopascal when submerged. Track design can be modified for more aggressive grip or made wider and longer to reduce the ground pressure contact. Fenders are added to minimize turbulence and drag.Autonomous navigational accuracy is achieved by fusing data from a single axis fiber-optic gyro (FOG) and a 3-axis inertial measurement unit. A dual-band GPS receives a fix when surfaced and is used as a cross-check on position. Shaft encoders on each drive side measure distance traveled.Accuracies of 2% of total range have routinely been achieved. Turn-in-place (TIP) and arc-turns

Aker Solutions to Supply Umbilicals for Liuhua FPSO

in the third quarter of 2018. The work scope includes more than 35 kilometers of dynamic and static power umbilicals for the Liuhua 16-2, 20-2 and 21-2 fields, linking the subsea development to a new floating production, storage and offloading (FPSO) unit.Power umbilical systems are bundled cable and fiber optic systems providing distribution of power, control and communication between subsea equipment on the seafloor and platforms or floating production facilities. The static section of the Liuhua 16-2 umbilical will be engineered using Aker Solutions' advanced manufacturing process called OsciLay

The standard Model 810 FRU is available with two or four threaded ports of size 1/2 or 3/4 inch. A 1/2 inch on-axis bore enables easy integration with an electrical slip ring, fiber optic rotary joint or both.The Model 810 utilizes sealed-for-life rolling element bearings, ideal for long endurance applications and low maintenance. Filled PTFE based seals run on a hardened surface to provide long service life, minimizing frictional heat generation and operational torque. For marine

The Sabertooth can work as an AUV, ROV and hybrid, has payload adaptability – which could soon also include a work class electric manipulator - and can work in 3000m water depth (with a target for 4500m). It can be operated via a thin fiber optic tether real-time communication/control at excursion ranges of up to 12km and can operate much further in AUV mode, without the fiber cable.For autonomous operations, Sabertooth is fitted with sensor reactive control and enhanced navigation capabilities, says Peter Erkers, sales director, underwater

; The SPM’s composite data set includes 18 instruments—platform and pod. They see a wide range of water properties. Plus, their simultaneous measurements have high resolution in time and space. The SPMs and their instrument suites (including the science pod) connect to the network of fiber optic cables. Each SPM has 1 Gbps bandwidth and 3000 watts power. As a result, live data are available on the Internet from sensors on the SPM platforms and their winched science pods.   Benthic Experiment Packages ADCPs are also aboard a couple of Benthic Experiment Packages (BEP) installed
