IMarEST President's Lecture on Failure

Engineering failures in the marine industry cost time and resources to correct and, sadly, sometimes resulting in loss of life. At his President's Day Lecture, Professor John Carlton FREng, Professor of Marine Engineering, City University London and the 109th President of the Institute of Marine Engineering, Science and Technology (IMarEST, UK), will retrospectively discuss some of the marine failures that he has encountered, with the aim of teasing out the underlying issues that have contributed to their causes.       The President's Lecture will be held Tuesday 11th October at IET London in Savoy Place, London WC2. Tea will... (read more)

Silicon Sensing’s Technology Supports Autonomous Mayflower Voyage

Two Silicon Sensing Systems ultra-precise AMU30 inertial measurement units (IMUs) will provide critical navigation data to the autopilot capability for the Mayflower Autonomous Ship (MAS) throughout her milestone transatlantic voyage this autumn. Setting sail this September, the 15-meter long, 5-ton MAS400 will repeat the Mayflower’s original epic voyage made 400 years ago. Led by marine research organization ProMare and powered by IBM, she will sail from Plymouth, England to Plymouth Massachusetts, USA. Instead of a captain and crew, she will use computer vision, machine learning, cutting-edge technologies and sensors to navigate and detect hazards.   Silicon Sensing’s AMU30 devices will form...

A18D in Business for AUV Survey Services

ECA Group demonstrates the high-performance of its mid-size AUV during deep survey missions
As announced in early 2018, ECA Group signed a cooperation agreement for subsea robotic services to Oil & Gas companies with a leasing offer on its latest generation A18D AUV creating a new dimension for its AUV services activity. Throughout 2018, ECA Group conducted several successful deep survey missions. The next generation AUV demonstrated its capabilities to perform multi-sensor surveys during deep sea operations (around 2,500m water depth) in the Mediterranean Sea.   A Comprehensive Survey Solution The A18D is the most compact multi-sensor AUV on the market for long-endurance deep water surveys (up to 3,000m). The AUV can capture... (read more)

Hydrographic Society Benelux

News Corporate Workshop 8th September 2004 Simrad BV, on behalf of the Hydrographic Society, gave a corporate workshop on 8th September 2004 entitled ‘Shallow Water Survey’. Almost eighty people attended this event held at the Rotterdam Airport hotel, which provided a good opportunity to gather information related to Innomar Technology, whose representative discussed parametric sub-bottom profilers, and Kongsberg Maritime, whose multi-beam, underwater instrumentation and motion sensors all came under review in the in the afternoon session. Companies have a good record on proven projects with quality and performance of equipment for the offshore, hydrographic and dredging market. For Kongsberg Maritime,... (read more)

High Precision Positioning

Extension of the Condamine Port in Monaco
The port of Monaco is undergoing an extensive construction process that will help double the port's capacity and protect it from heavy eastern swells and dangerous Mediterranean storms. The new port will include two unusual pontoon-type breakwaters as well as an additional hectare of land reclaimed from the sea. The project, costing more than 243 million euro, was initiated in June 1999 and is today slightly ahead of schedule. The existing port was built at the beginning of the century. At that time the water was too deep to allow, using building techniques of the day, construction of a jetty... (read more)

Technology in Focus: Bathymetric Lidar

With sea level rise and increases in the severity of extreme natural events, there has been a renewed push to further our understanding of the coastal zone. Fundamental to understanding risk in areas of high vulnerability is capturing the near-shore land and sea surface. Bathymetric Lidar is the most effective and cost-efficient technology to capture both the land and seafloor simultaneously to provide a continuous, detailed 3D elevation model along the coastline. Its ability to successfully capture elevation on both sides of the coastline, over areas stretching more than 100km along the coast, has made bathymetric Lidar the ‘gold standard’... (read more)

National Oceanography Centre

Strategic Regional Coastal Monitoring Now Implemented Along England’s Coastline.
With effect from 1 April 2011, a coastal monitoring programme is in place for the entire English coastline via a national network of coastal monitoring programmes. In addition to the well-established programmes (Southeast 2002 and Southwest 2006), new regional programmes have started in the Northwest (led by Sefton Council), the Northeast (Scarborough District Council), East Riding of Yorkshire (ERY Council) and Anglia (Environment Agency). All programmes have been designed on a similar risk-basis, tailored to local requirements and collect similar types of data using the same specifications. All programmes are fully committed to the principle of making their data freely... (read more)

A New Solution for Subsea Metrology

Combination of Acoustics and Photogrammetry
Invariably, metrology is required at the critical stages of field development and the main goal for improvement is to reduce the time taken for acquiring data. The technique discussed offers significant improvements in terms of time and required equipment. Offshore Construction During offshore construction several structures have to be interconnected by means of spools or jumpers. In order to determine the dimensions and relative attitudes of the connections, surveyors deploy ROV-mounted instrumentation. IMCA S019 Guidance on Subsea Metrology offers the following combined accuracy guideline: 50mm to 150mm in X,Y and Z axis 0.5° to 1° for relative pitch, roll and heading.... (read more)

Technology in Focus: Acoustic Doppler Current Profilers (ADCP)

Widespread Applications Stem from Diverse Measurement Capabilities
Rather than a spinning propeller, the Acoustic Doppler Current Profiler (ADCP) – just like dolphins and bats – uses sound to explore its environment. Operating underwater, the method works like hand-held radars used by police to catch speeding motorists. This article explains the technique of this frequently used type of instrument and some of its applications. A sound burst is emitted by the ADCP along beams angled downward. Echoes are returned due to scattering off particles carried by water currents. A second burst can be used to track movement over the seabed. By analysing these sound echoes, the ADCP makes...
