Monitoring Technologies

Highly advanced monitoring instrumentation will be the theme for YSI's participation at 'Ocean Business 2009' in Southampton (UK. The company will demonstrate two new technologies; the 'EcoMapper' a remote control underwater vehicle for plotting water quality over wide areas and a multiparameter monitoring platform that has been developed as part of two EU funded research projects.   The 'EcoMapper' is a unique remote monitoring system which only requires one person to deploy and retrieve, has integrated water quality sensors, intuitive mission planning software, and weighs less than 21Kg. It is ideal for routine mapping of lakes, reservoirs, rivers, estuaries and... (read more)

Iceberg Monitoring

A joint experiment between SUE Atomflot and ScanEx Research & Development Centre, Russia, was conducted in September 2011 on the overall detection of icebergs in the Vilkitsky Strait, which is the narrowest and most congested section of the Northern Sea Route between the Taimyr Peninsula and Severnaya Zemlya.   At the preliminary stage of the experiment the Atomflot Staff of Ice Operations reported the coordinates of icebergs, visually detected from board the icebreakers and using on-board radar. Equipped with this information ScanEx RDC conducted overall real-time imaging of the Strait area using radar and optical satellites data.   Information about... (read more)

Additional Excavator Monitoring Systems

The two installations are delivered in addition to the four systems already supplied to Martens en Van Oord, specialising in earthworks, both on land and under water. Both excavators are equipped with rotatable clamshells which are mounted on an extended stick. The inclination of the extendable stick and rotation are both measured and visualised real-time in combination with the standard boom/stick visualisation.   The excavators are mainly used for land dredging applications. As the excavators are equipped as stand-alone system they can also be placed on a pontoon for dredging on rivers and in harbors. The installation was performed by... (read more)

Automated Monitoring System

BioSonics is to unveil its latest generation of Automated Monitoring Systems at the OCEANS 2010 conference next month. This sonar-based tracking and monitoring system centres around BioSonics focused split-beam hydro-acoustic technology for the underwater assessment of marine life and other targets of interest. BioSonics split-beam transducers provide information on target location, size, swimming speed, and direction. Utilising an integrated orientation sensor and a dual-axis rotator, the resulting system can be programmed to scan and rotate at any desired angle or interval, thereby dramatically expanding the sampling volume. An echo sounder control unit provides automated data processing and storage as well... (read more)

Marine Monitoring Contract Extended

Fugro GEOS has won an extension to its real-time oceanographic monitoring programme for Huntsman Tioxide that is helping to improve the local marine environment off the coast of South Africa. Huntsman Tioxide South Africa owns and operates a marine effluent pipeline at Umbogintwini, just south of Durban in KwaZulu Natal. To gather information about it, Fugro GEOS installed a real-time system in June 2003 on a one-year trial basis. The system comprised an Aanderaa CMB 4280 Data Buoy and four Doppler Current Sensors (DCS) measuring current speed, current direction and water temperature at 10m intervals through the water column. The... (read more)

Monitoring the Shipwrecked Concordia

TRE and the Polytechnic University of Milan, Italy, in collaboration with the Department of Earth Sciences (University of Florence) have been monitoring the movement of the partially submerged cruise ship Costa Concordia since 20th January 2012 off the coast of Giglio Island. High-resolution images from the Italian COSMO-SkyMed constellation of satellites are being used to provide information on the position and movement of the ship, for integration with ground warning systems.   The analysis results are being continuously delivered to the Italian Civil Protection Department within hours of satellite acquisition.   In order to obtain the highest accuracy results, TRE...

Automatic Scour Monitoring Solution

The EIVA NaviSuite Edulis total solution allows for an automatic scour monitoring process, providing a data overview for a sound decision-making process. The suite is a plug and play total solution for continuous scour monitoring. It replaces the alternative of carrying out surveys manually on site, thereby reducing the number of manhours required. Cable free span, structural fatigue and deterioration, varying own frequency and other structural problems are practically eliminated, as the NaviSuite Edulis enables reaction to development of scour. Altogether, this translates into an efficient monitoring and maintenance operations. The NaviSuite Edulis does all the work throughout the scour... (read more)

On-Line Environmental Monitoring

GEMS recently completed a five-month environmental compliance monitoring programme in Fos-sur-Mer on the south coast of France. Two surface buoys were deployed to monitor sediment plume dispersal during dredging operations, and offer protection for the commercially sensitive oyster beds in the vicinity. Each buoy was interfaced to a subsea YSI-6600 sonde fitted with turbidity, conductivity, temperature and pressure sensors. Data were relayed to GEMS UK-based ARTEMeS server at ten minute intervals via a GSM modem programmed with GEMS proprietary firmware.   The systems were designed, built and deployed within one week of order using the joint expertise of GEMS Survey...

Monitoring Ormen Lange

Tracking Challenging Gas Pipeline Conditions
Ormen Lange is a large gas field in the northern North Sea (the Norwegian Sea) at water depths ranging from 800 to 1,100 metres and close to the back wall of the Storegga sub-sea rock slide. The slide left an extremely rough seabed with a profusion of hills and valleys. This article focuses on the pipeline from field to on-shore processing facilities and presents solutions to strong currents and rough seabed. Ormen Lange is estimated to be the second largest gas field on the Norwegian shelf. Norsk Hydro is responsible for the development phase of Ormen Lange and has extensively... (read more)

Oceanology Improves Weather Monitoring

An AXYS WatchMate1.8DM buoy has been deployed in the external port of La Coruña, Spain. The WatchMate oceanographic buoy strengthens the weather monitoring programme operated by Puertos del Estado (PdE) in the Galicia region. The buoy system monitors additional strategic environmental parameters over the existing REDCOS TRIAXYS buoys for operation of the port and to improve the local marine weather forecasting models. The WatchMate transmits oceanographic and meteorological data like directional waves, marine currents, salinity, sea surface temperature, wind (speed and direction), atmospheric pressure and temperature. Puertos del Estado can also expand these capabilities to add more sensors including: water... (read more)
