Offshore Environmental Surveys

Introduction to UK Legislation and Guidelines
This is a brief introduction to UK offshore marine environmental survey legislation and guidelines, written from a fairly narrow perspective: that of a contractor providing such survey services to the oil & gas industry. Legislation requires environmental surveys of the North Sea but the extent and definition of these is open to interpretation, with quite a variety of standards and guidelines to choose from or ignore. Legal FrameworkUK environmental legislation transposes European Community (EC) directives on the environment. The prime EC directives are Council Directive 92/43 ‘on the Conservation of Natural Habitats and of Wild Fauna and Flora’ (‘the Habitats... (read more)

Valeport Launches Environmental Optical Sensors

Valeport, a British designer and manufacturer of hydrographic and oceanographic instruments, has launched two environmental optical sensors, a standalone turbidity sensor and a fluorometer. The first one of the new range, the Hyperion Turbidity, is the industry’s first standalone turbidity sensor that combines a Nephelometer and OBS readings in the same instrument. Created for inshore, coastal and oceanographic monitoring, this sensor delivers a minimum detection level of just 0.03 NTU (nephelometer) and can measure turbidity up to 6,000 NTU (OBS). The titanium housing, data output up to 16Hz and low power requirements ensure the sensor can be placed in situ for... (read more)

Environmental Training Course for Dredging

A training course on Environmental Aspects of Dredging is to be held in Delft, The Netherlands, in the spring of this year. Organised by the Postgraduate Academic Programme (PAO) of the Delft University of Technology, it will take place on 19th and 20th April 2012. The Training Course is based on the book Environmental Aspects of Dredging that was produced as a joint effort by the Central Dredging Association (CEDA) and the International Association of Dredging Companies (IADC) and published by Taylor and Francis in 2008. The lessons are enhanced by the up-to-date knowledge of the course leaders who are... (read more)

A New Tidal Monitoring System for Port of London Authority
The Port of London Authority (PLA) has had an extensive tide gauge network for many years. However, the existing system, installed in the 1990s was becoming increasingly unreliable providing inconsistent information due to a number of factors. There was a pressing need to develop a state of the art tidal monitoring system across the outer area of the PLA responsibility utilising the latest communications technology whilst ensuring resilience to guarantee 24/7 working of the port could be maintained at all times. OceanWise, working with Valeport, was asked in 2013 to design, build, install and test a new monitoring system to... (read more)

Congo Environmental Survey for Creocean

Creocean has recently successfully completed an Environmental Baseline Survey (EBS) for TOTAL-E&P-Congo on the Moho-Bilondo field. The survey, carried out with scientific support from Thales Geosolutions South Africa and with the technical support of an RV Geoexplorer, provided water quality, sediment and benthic fauna information, at 700 to 900 metre depth. The data collected will describe the environmental sensitivity of the oil field. Creocean scientists use all parameters of the marine environment, including the biological indicators developed specifically for oil and gas areas. (read more)

1.2m Tern Buoy for Gardline Environmental

UK-based Ocean Scientific International Ltd (OSIL) have recently supplied a 1.2m Tern Buoy to Gardline Environmental, for installation in Cyprus. The buoy is equipped with a Nortek AWAC, acquiring full profile current speed and direction and wave data in addition to other ancillary parameters including GPS positioning. Data from the AWAC is currently transmitted via GSM. However, the buoy has also been equipped with the option to swap comms to Iridium satellite. The buoy system is robust, with all cables held internally, protected by the rugged enclosed top section, which has been designed to minimise damage from the elements or... (read more)

5-Year RADARSAT Environmental Monitoring Contract

MDA and the Marine North East Region (RMNE) of PEMEX Exploration and Production (PEP) have signed a five-year contract for the continued monitoring of natural oil seeps and oil spills in the Gulf of Mexico using RADARSAT data. This contract ensures data continuity and integrity in support of environmental stewardship and exploration activities in PEP-RMNE's area of operations.   PEP has been using RADARSAT-1 operationally since 2001 when it established its maritime surveillance strategy for the Campeche Basin. Image analysis experts are able to characterise oil on the sea surface by its origin - natural oil seep, oil spill from... (read more)

Monitoring Environmental Concerns in Lake Victoria

UK-based OSIL recently completed the installation of two data buoys along Lake Victoria in Kenya to help manage the local environment. The buoys will be used to monitor various environmental concerns including hyacinth menace and contamination of the lake water. In addition to monitoring atmospheric components of the lake, such as moisture, oxygen levels and temperature, the sensors on the data buoys will also measure wind direction and levels of potentially harmful chemicals in the lake. By better understanding the environment, one benefit is that fishermen will be provided with real-time information on wind patterns, thus helping them to avoid being... (read more)

Efficient Marine Navigation through Understanding Environmental Conditions

ARGOSS and WL Delft Hydraulics, together with research and maritime industrial parties in Singapore have started a strategic cooperation to develop satellite altimeter enabled services to improve ocean and coastal current forecasting and to develop a new generation of maritime decision support systems onboard of vessels. The project is coordinated by ARGOSS and will take approximately three years. By improving ocean and coastal current nowcasting and forecasting the newly to be developed services will contribute to safety at sea, fuel efficiency and so help to preserve our environment. ARGOSS is an innovative metocean company developing and providing metocean services based... (read more)

Collaboration on Rapid Environmental Assessment Exercise

A group of marine-industry technology providers gathered recently in San Diego, USA, using OceanServer Technology's Iver2 AUVs as the payload platform, to demonstrate improvements for both sonar and magnetic sensor data capture and subsequent 'in-stride' and post-mission data analysis methods. These methods are emerging through cooperative developments in commercial and military survey operations. Participating for this five-day exercise in the waters off Coronado, were companies including EdgeTech, L-3 Klein, Marine Magnetics and technical representatives from both the US and Canadian Navies. A total of 37 individual AUV missions, simulating battlefield data collection methods, provided a variety of high-resolution imagery and... (read more)
