THE IMPORTANCE OF EFFECTIVE DREDGE MONITORING
Nearly all the major ports and waterways in the world have at some time required new dredging works (capital dredging), as technological developments and the requirement to improve cost effectiveness have lead to larger, more efficient ships, and expanding coastal infrastructure which more recently includes provisions for renewable energy developments.
REQUIREMENTS FOR MONITORING SUBSEA ENGINEERING WORKS WITH FLOATING PLATFORMS
As published in Sea Technology magazine September 2014 Issue:
In recent years there has been an increase in the requirement for subsea engineering works and geophysical exploration due to dredging projects, well drilling and mining activites, renewable energies, port development, fisheries and leisure activities, etc.
DREDGE MONITORING IN DOHA NEW PORT PROJECT
The New Port Project in Doha, Qatar, is an ambitious development spanning a 26.5 square kilometre area that will result in a world-class greenfield port facility incorporating the new port, a new base for the Qatar Emiri Naval Forces, and the Qatar Economic Zone 3 Canal.
Balancing development with protection of the environment is a key concern for the New Port and construction is taking place with environmental preservation paramount; multiple s...
GSI UNDERTAKE BATHYMETRIC STUDIES IN CENTRAL ANDAMAN TROUGH
The oceanographic research vessel RV Samudra Ratnakar, recently delivered to the Geological Survey of India (GSI) by Korean manufacturer Hyundai Heavy Industries, is specially designed to carry out sea bed-mapping and mineral exploration in deep waters, along with geo-scientific oceanographic research.
The ship is equipped with high-end technologically advanced instruments needed for geological, geophysical and geochemical explorations in offsho...
OCEANLAB CRUISE ASSISTED BY OSIL MULTIPLE CORER
The 60th research cruise of the RSS James Cook completed recently, having spent 5 weeks in the North East Atlantic in rough seas and high winds, collecting samples from the Darwin Mounds and Rockall Bank (North-West of Scotland) for Oceanlab researchers Dr. Evina Gontikaki & Neils Jobsvogt.
FULMAR BUOY CONTRIBUTES TO OCEAN OBSERVATORY
The Instituto de Investigacións Mariñas (CSI-IIM) have utilised an OSIL Fulmar Buoy for their contributions to the RAIA Iberian Margin Ocean Observatory.
ENVIRONMENTAL MONITORING IN LAKE VICTORIA
The Kenyan Government (Meteorological Department and Kenya Marine and Fisheries Research Institute (Kemfri)) contacted OSIL with regard to a unique problem they were encountering.
RAPID DEPLOYMENT FOR THE SMALL FIELD BUOY
The Northern Ireland Environment Agency were asked to investigate a fish kill event at the popular angling location of Ballykeel Lough Erne, Co. Down.
TIDAL TURBINE ASSESSMENT BY ADCP
Tidal energy can provide a highly predictable and sustainable level of energy that is dependent on the tidal cycle.
The emerging technologies for tidal energy generation provide two very different approaches: impoundment schemes, such as barrages and lagoons, or streams that directly utilise the tidal current – that is, tidal stream turbines.
BIOLOGICAL MONITORING IN SKOMER MARINE NATURE RESERVE
The Skomer Marine Nature Reserve is one of only three marine nature reserves in the UK. This is the only one in Wales and is run by the Countryside Council for Wales. Skomer’s waters are famed for their underwater scenery and amazing range of marine life. Situated as it is where northern and southern species overlap, there is a huge variety of wildlife of all shapes and colours – making it a great place to study and monitor changes in the ma...
CODAR’S HF RADAR SYSTEM HELPS SPANISH AUTHORITIES MONITOR THEIR COASTLINES
In 2002, Spain witnessed the Prestige oil tanker sink off its north-west coast and it acted as a wake up call highlighting the importance of preparing for such a crisis. It led to Spain’s government prioritising the improvement of maritime protection and coastal management proceedings.
ADCP USED IN BERTH MANAGEMENT SYSTEMS
One of Strainstall UK Limited’s primary marine safety systems is their Berth Management System, which is used chiefly for the docking of VLCCs (oil tankers) and LNG (liquid natural gas) carriers. The Berth Management System provides assistance to vessels on their approach to the berth and during mooring by monitoring the conditions of the sea and surrounding area to ensure the complete safety of the vessel. The system undertakes conti...
LOW-COST DREDGE MONITORING SYSTEM IN ONE WEEK
With the wide range of instruments that OSIL represent, they pride themselves in being able to provide complete solutions to the many marine and environmental problems that their clients present them with. When GEMS, Geotechnical Engineering and Marine Surveys, approached OSIL with an urgent requirement for a low cost, dredge monitoring system that they needed to be ready to ship within a week, their reaction was no different.
MONITORING HABs IN SPAIN’S RIA DE VIGO WITH OSIL’s FC60 MINIBAT
Situated in Galicia in the north west of Spain, the Ria de Vigo is a river valley that has sunk tectonically and has been flooded by the sea. The Ria is connected to the open sea via a narrow northern channel and a wider and deeper southern channel. Due to the low tidal Circulation, the Ria de Vigo can be susceptible to harmful algal blooms (HABs), which can kill fish, contaminate seafood with toxins and fundamentally alter whole ecosystems.
