NCT-2030M Dual-frequency GPS Receiver

NavCom Technology, Inc. has announced the addition of the new NCT-2030M to its line of dual-frequency GPS receivers. The NCT-2030M receiver is a 12-channel, versatile, low-cost, dual-frequency GPS engine offering 64 megabytes of internal memory for data logging. The sensor delivers sub-millimetre dual frequency carrier phase performance and, where free WAAS or EGNOS corrections are available, can achieve half-metre real-time horizontal positioning via two dedicated SBAS channels. The NCT-2030M incorporates 1 PPS output, Event-in and CAN ports as standard. A simple software upgrade can add RTK capacity, raw data rates up to 50Hz and positioning rates up to 10Hz. Factory...

Autonomous Semi-submersible

Autonomous Surface Vehicles Ltd, with Seaspeed Technology Ltd, have exhibited the first 5.5-metre Survey Autonomous Semi-Submersible (SASS) vehicle. SASS vehicles are used to collect survey or surveillance data of all kinds from the ocean. SASS vehicles have both civilian and military applications, ranging from oceanographic and fisheries research to anti-terrorist surveillance and mine countermeasures. A detachable nose-cone enables a variety of in-water sensors to be fitted to suit any particular application. It can also deploy sensors or smaller daughter vehicles from a winch housed in the nose-cone. SASS involves an unmanned submerged torpedo-like body running below waves with a strong... (read more)

Phoenix Augments ROV Fleet

Phoenix International, Inc. has acquired two powerful, heavy-duty work Remotely Operated Vehicles (ROVs) to augment its expanding ROV fleet: a 200 hp Perry Slingsby Triton 210 and a Soil Machine Dynamics 400 hp NEREUS II ROV. Both systems can operate in a free-flying or tracked mode and are capable of performing intervention, sampling and submarine cable/pipeline related tasks. The systems include hydraulic manifolds capable of supporting a diversity of underwater tools and tooling systems, dual 7-function Schilling manipulators, TSS 340/350 cable/pipeline tracking systems, cable gripping and cutting WebTools and water jetting systems for cable/pipeline burial and excavation projects. The vehicles... (read more)

Measuring Waves in Makassar Strait

Fugro GEOS has successfully completed an oceanographic programme measuring surface and internal waves in the Makassar Strait, offshore East Kalimantan, Indonesia for the Total E&P Indonesia-Donggala project. The measurements were made using a single oceanographic mooring deployed in about 1,900m of water and serviced on a regular two-monthly basis over the ten-month period of the programme. The mooring had nineteen instruments configured to measure currents, waves, tidal elevations and seawater properties throughout the water column. The instruments consisted of ADCPs (acoustic Doppler current profilers), conventional rotor current meters, temperature sensors and a water level recorder. An important aspect of the... (read more)

New Sound Velocity Sensor

The latest sound velocity sensor from Applied Microsystems Ltd. (AML) offers new hi-tech features in the smallest of packages. Available from OSIL, the Micro SV is constructed from new materials that eliminate thermal expansion and reduce corrosion. This means that users can obtain a greater level of accuracy at ± 0.05m/s, particularly in high-speed profiling applications, where the sensor can sample up to 25 times per second. The Micro SV has the capability to log-date continuously or on demand and by user-selected time, depth or sound velocity increments. The user benefits from standard Windows compatible software, which allows data to... (read more)

200th Seaeye System for Vietnam

Seaeye Marine has delivered its 200th ROV system to PTSC in Vungtau, Vietnam. This Panther Plus system includes a TMS and a Seaeye Launch and Recovery System featuring an elevated 'A' frame pivot point allowing the deployed package to clear a two-metre ship's side or guard rail. Heavy-duty five and six function manipulators are included, together with a standard array of sensors and capacity for additional tooling. Four PTSC pilot technicians undertook a 14-day factory training-course in the UK that included both operational and technical training on the system. Further training will be provided in Vietnam following commissioning of the... (read more)

AC-ROV Concept Vehicle

Ac-cess and their engineering partners at All Oceans (UK) have been researching, developing and testing materials and components leading to development of the AC-ROV concept video camera and sensor platform. This has six thrusters, all identical, to give the operator all the viewing control that will ever be needed. Four full-bore vectored horizontal thruster units give equal forward, sideways and pan control, whilst two vertical units give powerful up, down and pitch control. A one handed (left or right) 5-axis controller makes for a very simple and versatile operator interface. Flight Freeze is a further feature that may be selected,... (read more)

The Latest from CTG

The Chelsea Technologies Group is launching the COVELIA correlation velocity Log at OI. COVELIA has been developed to provide Autonomous Underwater Vehicle (AUV) and ROV navigation systems with a highly accurate speed-over-ground velocity measurement. This instrument is designed to replace conventional Doppler velocity logs, which can be particularly inaccurate at the low speeds which AUVs operate. The COVELIA system comprises a multiple element transmit and receive array and a small electronics package to perform the digital signal processing. The array incorporates over 20 individual transducers to perform the complex multiple transmissions and simultaneous multiple element receive functions required for the... (read more)
