Imagenex Adds Sonar and Sensor Interface Relay

Imagenex has released the Model 878 high-resolution sidescan sonar which runs two sonars simultaneously on each side at different sound wavelengths for enhanced image clarity. The new DT100 Sensor Interface Relay (SIR) provides a central connection point for bathymetric sensors including sonar (1 or 2 units), GPS, MRU, gyro/heading, and sound velocity. The DT100 multibeam echo sounder has been revised. The sidescan sonar Model 878 'RGB' (triple simultaneous frequencies) has undergone a facelift and become more affordable. Both models are equipped with an optional echo sounder and a built-in orientation module as well as depth and temperature sensors. Powered by... (read more)

CTD Sensor with Integrated UV Antifouling LED

A UV-LED (ultraviolet, 250-300nm @500µW, light-emitting diode) is integrated into the conductivity sensor quartz cell (patent pending) of Idronaut’s 305Plus CTD probe. The UV-LED sterilises the early growth of biofouling, thus eliminating environmental drift in a conductivity sensor. The Idronaut 305Plus CTD Probe complies with the European rules which do not permit the use of Tributyltin (TBT), a very toxic and poisoning (carcinogenic) substance which has been banned by the international government agencies. It is mandatory to protect any recessed conductivity cell, which presents a very small diameter and may get contaminated or even clogged. It also operates in polluted... (read more)

Longest Multi-Sensor AUV Pipeline Inspection

KONGSBERG has completed the world's longest multi-sensor AUV pipeline survey using one of its HUGIN 1000 Autonomous Underwater Vehicles (AUV). The pipeline inspection took place from 9th to 11th February 2011, in the Hjelte fjord near Bergen, Norway and the HUGIN 1000 was operated from the Royal Norwegian Navy vessel HNoMS Maloy. The subject of the inspection was two subsea pipelines going to the Mongstad oil refinery. The HUGIN 1000 AUV was equipped with a suite of KONGSBERG imaging equipment including the HISAS 1030 synthetic aperture sonar, EM3002 multi-beam echo sounder and an optical camera with LED lighting. The instruments... (read more)

Sensor Combination for Environmental Monitoring in Gulf Spill

Chelsea Technologies Group has seen growing demand for its UV AQUAtracka fluorimeter to monitor the extent and dispersion of the oil spill in the Gulf of Mexico. Originally designed for military use, these highly sensitive fluorimeters are monitoring the extent of the oil from surface waters to full ocean depth. The UV AQUAtracka is now being used in combination with the FASTtracka Mark II fast repetition rate fluorimeter to monitor the effects of the oil on the primary productivity of the Gulf. The FASTtracka II has undergone extensive challenge testing to characterise its response to contamination events in the aquatic... (read more)

Wärtsilä Unveils Targetless Laser Sensor for Offshore Wind Farms

Wärtsilä has launched SceneScan, a targetless laser sensor for offshore wind farms. SceneScan Monopole is among the first laser sensors developed for offshore wind farm applications where the need for installing fixed reflective targets is eliminated. This technology is designed to increase safety onboard service operation vessels (SOVs), since vessel positioning sensors that rely on targets fixed to the structure, are often unreliable because of poor placement, poor quality, and obscurement by workers on the platform. SceneScan has been designed and developed by Guidance Marine, which was acquired by Wärtsilä in 2017. SceneScan Monopole’s advanced software allows the measurement of... (read more)

Oil Sensor-equipped Smart Buoy Delivers Data via Satellite

A smart navigation buoy system has started delivering real-time measurement data via satellites of oil and some other water quality parameters in the Baltic Sea. It is located south of Helsinki in the Gulf of Finland. The monitoring data gives many advantages to oil spill response teams and helps revealing illegal oil discharges. The system is part of SYKE’s Grace project cooperation and is manufactured by Meritaito. The data is freely available online. The real-time remote measurement is a big advance in oil detection and environmental monitoring. It is significantly quicker with satellite data transfer and can provide more accurate... (read more)
