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)

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...

Vessel Corrosion Monitoring

MICAD Marine has begun to include Vessel Corrosion Monitoring as standard equipment in all of its Marine Systems. Corrosion is one of the greatest enemies of all vessels and there are several protective measures that vessel owners can take to eliminate this risk. The typical solution is the placement of zinc on various parts of metallic objects making up submersed parts of the vessels. This new monitoring device offers display and archive of the current status of cathode protection, as well as a permanent log of the entire protective system employed on the boat, for its entire history. If zinc... (read more)

Typhoon Monitoring Instrumentation

Following an international competition, NTU has selected Axys' Triaxys directional wave sensor to measure the waves generated by typhoons approaching the coast of Taiwan. The Triaxys sensor will be integrated onto NTU's modified Atlas (Autonomous Temperature Line Acquisition System) metocean buoy.     Atlas is a 2.3m diameter toroid fabricated with fiberglass over a foam core.  Axys' proprietary Triaxys wave sensor will deliver the highly accurate directional wave data required for scientific research and weather forecasting.   Axys' exclusive representative in Taiwan, Sino Instruments Co. Ltd. facilitated the purchase and will also assist NTU with the integration of the sensor. ... (read more)

Environmental Monitoring Buoy

UK-based OSIL recently launched its new 1.2m Tern buoy. The platform is designed for extended deployment in harsh coastal environments in deeper water depths, and is suitable for all applications, including scientific studies, water quality monitoring, coastal engineering projects, harbour and coastal monitoring, and maritime traffic control.                                            The system is robust, with all instrumentation and cables held internally, protected by the rugged enclosed top section, which has been designed to minimise damage from the elements or interference. All sensors... (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...

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)

Long-term Environmental Monitoring

The Marine Institute in Ireland has ordered two YSI 6600 EDS environmental probes from OSIL. The EDS (extended deployment sonde) was carefully selected for its ability to measure environmental parameters over a long deployment period. The YSI probes will be used for monitoring work in the vicinity of aquaculture production sites such as salmon farms and mussel lines to learn more about harmful algal bloom in Irish coastal waters. Each YSI 6600 EDS will be measuring fifteen parameters that include turbidity, chlorophyll, rhodamine, dissolved oxygen, and pH. The YSI data will then be used for research purposes on the Biological... (read more)
