IHC Hydrohammer recently commissioned the S-1800 hydrohammer with 5.5m pile guiding for the Chinese offshore wind market.

Jiangsu Longyuan Zhenhua Marine Engineering, a joint venture between ZPMC and Longyuan, is using the S-1800 hydraulic piling hammer from Chinese contractor 3rd Harbour Engineering to drive flanged monopiles for the Longyuan Jiangsu Rudong offshore wind farm.

With a total of 36 flanged monopile foundations and 14 tripod foundations, supporting 4MW turbines, the Chinese offshore wind farm will deliver 200MW. The joint venture already installed 31 foundations until now for this project.

Deep Vision

The commercial prototype of Scantrol’s Deep Vision project, has been tested in the sea for the first time. The success of the first test bodes well for the final steps of the project before the system will be launched at a CRISP cruise in March.

Deep Vision is an underwater vision system that consists of a stereo camera and lights mounted in a frame that attaches to the cod end of the trawl. The system takes photos of all fish passing through the trawl before uploading them to the Deep Vision software where the catch can be analysed without bringing the fish aboard the vessel.

Project Manager at Scantrol Deep Vision, Håvard Vågstøl, at work with the frame before the first sea trial: — We are very excited to see the drawing board design transform into a commercial product.

In addition to information about time and depth of the images, the current version of the Deep Vision software allows for semi-automatic length measurement and species recognition.

“Our long term plan is to have a fully automatic length measurement and species recognition combined with a sorting mechanism. We can only imagine the possibilities for the commercial fisheries when the system allows for sorting in order to 32 better control the catch and reduce bycath,” says Marketing Coordinator at Scantrol Deep Vision, Hege Hammersland-White.

UT2 December 2014 January 2015 Lights and Cameras

Kongsberg CCD

Kongsberg Maritime has launched an all new high resolution monochrome CCD camera.

The OE15-100D camera is smaller, yet has a deeper rated housing and wider angle of view (AOV) in water than any of its predecessors, whilst still maintaining Kongsberg’s high standard of build and image quality.

With near silicon intensifier target (SIT) performance in low light level conditions, an exceptionally wide AOV (102deg in water) and a water corrected optical arrangement that minimises distortions and aberrations, the OE15-100D is ideally suited to mid water navigation tasks, general observation and situational awareness as well as tether monitoring applications.

The OE15-100D camera is available in both CCIR (PAL - OE15-100D 625 line, 50Hz) and EIA RS170A (NTSC - 525 line, 60Hz) output formats. The highly advanced internal electronic it suitable for use on all classes of remotely operated assembly is protected from the harshest of environments vehicles. The camera will accept a wideband input voltage by a titanium alloy housing, depth rated to 4500m. range between 16 and 30V dc, with a maximum current draw of 220mA. The OE15-100D camera measures only 86mm in diameter at the widest point and 211mm in length The OE15-100D further enhances Kongsberg Maritimes (excluding connector).

UT2 December 2014 January 2015 Ice Scientists Observe Rising on the West Antarctic shelf

The water temperatures on the West Antarctic shelf are rising. The reason for this is predominantly warm water from greater depths, which as a result of global change now increasingly reaches the shallow shelf.

There it has the potential to accelerate the glacier melt from below and trigger the sliding of big glaciers. These data are published by scientists of the GEOMAR Helmholtz Centre for Ocean Research Kiel together with colleagues from the UK, the US and Japan in the international journal Science.

The Antarctic ice sheet is a giant water reservoir. The ice cap on the southern continent is on average 2100m thick and contains about 70% of the world’s fresh water. If this ice mass were to melt completely, it could raise the global sea level by 60m.

Therefore scientists carefully observe changes in the Antarctic. In the renowned international journal Science, researchers from Germany, the UK, the US and Japan are now publishing data according to which water temperatures, in particular on the shallow shelf seas of West Antarctica, are rising.

“There are many large glaciers in the area. The elevated temperatures have accelerated the melting and sliding of these glaciers in recent decades and there are no indications that this trend is changing,”says the lead author of the study, Dr. Sunke Schmidtko from GEOMAR Helmholtz Centre for Ocean Research Kiel.

For their study, he and his colleagues of the University of East Anglia, the California Institute of 48 Technology and the University of Hokkaido (Japan) evaluated all oceanographic data from the waters around Antarctica from 1960 to 2014 that were available in public databases. These data show that The higher water temperatures on the shelf could accelerate the melting of glaciers from below. The ice slides towards the sea more quickly. Photo: S. Schmidtko, GEOMAR

The idea of a standardised offshore electricity generator for the wave industry reached a significant milestone in November, when the WavePOD prototype produced its first power in laboratory tests.

The prototype, which comprised a drive train, cylinder frame and power take off, was developed by Bosch Rexroth and Aquamarine Power as part of a collaboration including some of Europe’s leading wave energy developers, utilities and academic institutions. The goal is to develop an industry-wide power take off that will generate electricity reliably and cost- effectively at sea.

Siemens, owner of Bristol based- Marine Current Turbines, is understood to be pulling out of the tidal energy business. The company blames slow development of the market.

Earlier this year, Siemens suspended work on a 10MW tidal array off the coast of North Wales. This would have featured MCT’s SeaGen tidal generator.

Before then, the government withdrew a £10m grant due to MCT for failing to find another source of funding in order to fit with the government’s 2016 deadline.

ASI Marine Wins On Two Continents With Falcon

In both Australia and Canada, ASI Marine has established the record for the longest tunnel swim with a Saab Seaeye Falcon ROV. By creatively modifying its Falcon, ASI was able to send the vehicle through a pipeline stretching over 4km under Gladstone Harbour, Queensland to Curtis Island. It also sent the same modified Falcon through 5km of feeder pipes in Lake Ontario.

Under Lake Ontario in Canada, the Falcon worked in the worst freezing conditions on record to run 5km down each of three separate 1.6m diameter pipes in a unique project to create the world’s largest cooling system. The Falcon was fitted out with video As a module-focussed concept, the This deep lake cooling system feeds plus profiling sonar with a BlueView Falcon generates automatic diagnostics the city of Toronto in summer with imaging sonar and Mesotech on power-up to ensure each device is cold water to cool the city’s offices scanning sonar as additional fully interfaced and working correctly. – as a sustainable alternative to navigation aids. air conditioning – then sends the In modifying the Falcon to undertake water onwards to top-up Toronto’s The Falcon’s intelligent architecture the longest runs ever attempted by a municipal water supply. means each device on the vehicle vehicle of this class, ASI Marine has can have its own microprocessor for continued its tradition of developing Bob Clarke, ASI Marine’s senior individual control and systems can innovative solutions for demanding operations manager, said that this be easily changed or added. projects. was achieved by modifying the power supply to the system so that the Falcon could operate over 5km of tether.

This was particularly important for the Australian project, as their client wanted just a single point of access to inspect the 4.3km pipeline. The inspection on the Santos Gladstone LNG Project was conducted with the Falcon to confirm the condition of the pipeline that was pushed through the utility tunnel.

The utility tunnel had been bored to minimise environmental impact at the site and to provide a protected conduit through which to pass the pipeline and other utilities.

This was the last segment of the 56 pipeline that delivers liquefied natural gas (LNG) to the Santos LNG plant on Curtis Island. The ROV inspection was conducted to ensure the pipe’s integrity during and after the push.

UT2 December 2014 January 2015 Nuclear Option Hat trick of contracts

James Fisher Nuclear (JFN) of Egremont, Cumbria in England has just released video footage by kind permission of Sellafield Ltd, of one of its three Teledyne SeaBotix vLBV300 Remotely Operated Vehicle (ROV) systems currently operating and working in hazardous environments within storage ponds at the Sellafield nuclear facility in Northern England.

The ROV is typically used for grabbing and lifting a cobalt 60 cartridges weighing approximately 5Kg. Since May this year, over 4500 Kg of waste material has been inspected and repositioned within storage ponds at Sellafield in over 200 hours of operations using Teledyne SeaBotix vLBV300 ROVs.

The vehicles are fitted with a specialised grabber arm skid which allows the operator to remotely position the arm vertically below the center of mass of the vehicle. This technique ensures the vehicle remains stable and fully manoeuvrable while it carries heavy loads.
