Bubble Barrier Could Prevent Plastics from Entering the Oceans

Video Included
A Dutch company says it has found a bubble-based solution for the tonnes of plastics that enter the oceans from rivers and canals. The company produces a bubble screen by pumping air through a tube with holes in it, which is located on the bottom of the waterway. The Bubble Barrier, as the system is called, creates an upward thrust, which brings waste to the surface of the water. Positioned diagonally in the waterway, the Bubble Barrier uses the natural current to guide the plastic to the catchment system at the riverside. Ships and fish can bypass the barrier, but...

MSI Provides Metocean Data to Support Construction of Breakwater

MSI, a company that provides meteorological and oceanographic (metocean) measurement services, was recently contracted to install a range of equipment for a period of between 2 and 4 months in the Moroccan port of Laayoune. The city of Laayoune is a hub for fishing and for phosphate mining in the region.As part of port expansion plans, contracting company Archirodon was awarded an EPC contract which includes the construction of a new 950m breakwater. Part of the breakwater will act as a quay structure for the berthing of vessels to provide loading/unloading facilities of solid and liquid bulk. Other infrastructure that... (read more)

Significant Changes in Wave Conditions Due to Climate Change

Research finds that a warming planet will also alter ocean waves along with more than 50% of the world’s coastlines. This study, published in Nature Climate Change, reports significant implications for coastal flooding and erosion. As part of the Coordinated Ocean Wave Climate Project, ten research organisations, including the British National Oceanography Centre (NOC), combined to look at a range of different global wave models in a variety of future climate scenarios, to determine how waves might change in the future. "We are proud to be involved in this worldwide collaboration in wave science: this paper helps us to understand and quantify the... (read more)

Old Fashioned or Just Safe

Not long before this issue of Hydro International went to press, a major problem with Galileo, the European equivalent of the American GPS system, occurred. A few days later, the malfunctioning system has still not been corrected. It appeared to be an incident related to the Galileo ground infrastructure that resulted in a temporary interruption of the Galileo Initial Services. Disrupted Hydrographic and Oceanographic Operations Galileo is widely used by most of the commercially available receivers. Multi-constellation GNSS receivers will remain unaffected and compute position and timing using other constellations, said experts for the European GNSS Agency, the industry, the... (read more)

Ocean Robots Make Subsea Cable Surveys Faster and Cheaper

Autonomous underwater vehicles (AUVs) can perform subsea cable surveys faster and more economically than ships with towed instruments, according to a recent study of researchers from the Woods Hole Oceanographic Institution (WHOI). “AUVs can cut down on ship costs and weather delays while reducing the time required to gather the data operators need to assess their underwater infrastructure", said Anthony Kirincich, a physical oceanographer at WHOI. Subsea Cable System WHOI researchers deployed an AUV to survey a subsea cable system in Buzzards Bay that links Martha’s Vineyard, an island located south of Cape Cod in Massachusetts, to grid power from the mainland. Buzzards Bay is a bay of the Atlantic Ocean adjacent...

Exploring the Wold’s Most Unknown and Least Protected Ocean

Increasing our knowledge of the marine fauna that populates the depths and the physical systems governing ocean behaviour is essential for a scientific community seeking to better understand climate change and assist political strategies to protect the underwater environment. The remote setting creates challenges for scientists in what are increasingly collaborative endeavours, involving multi-disciplinary teams that are disparately located. Furthermore, researchers are often using advanced instruments that have never before been deployed in the field; if something goes wrong, troubleshooting can be a drawn-out and frustrating process. Lack of Decent Communication Until recently, a major aggravating factor has been the... (read more)

Intruder Sonar to Protect Eastern European Waterside Energy Facility

Underwater intruder detection technology from maritime security specialist Sonardyne International has been chosen to secure the coastal perimeter of a critical national energy infrastructure (CNI) facility in Eastern Europe. Sonardyne's Sentinel Intruder Detection Sonar (IDS) will be deployed to detect unauthorised divers and subsurface vehicles approaching the facility from the water. The installation, at an undisclosed location, is the first phase of a site-wide project led by MARSS Group to enhance security at the facility with their NiDAR long-range air, land and underwater situational awareness system. Reliably detecting underwater intruders or vehicles in real-time at long range is essential to provide... (read more)

Live Transmissions Help Explore Secrets of the Deep

Live transmissions from unexplored regions deep below the Indian Ocean have underlined the role that reliable, high-speed broadband at sea is playing in expanding knowledge and promoting a more sustainable future. Increasing our knowledge of the marine fauna that populates the depths and the physical systems governing ocean behaviour is essential for a scientific community seeking to better understand climate change and assist political strategies to protect the underwater environment. Drawn Out and Frustrating Process The remote setting creates challenges for scientists in what are increasingly collaborative endeavours, involving multi-disciplinary teams that are disparately located.

Trelleborg Supplies Bespoke Gasket to Protect Historic Ship on the Åland Islands

Trelleborg’s marine and infrastructure operation has supplied a specially designed Gina gasket (G110-80) to a bespoke dry dock, built for the purpose of protecting the renowned historic ship Pommern, located in Mariehamn on the Åland Islands in the Baltic Sea. Built on the Clyde (Scotland) in 1903, Pommern is the only tall ship in the world that has remained structurally unaltered since her days in active service. Since 1953, she has served as a museum ship, moored next to the award-winning Åland Maritime Museum. The dock, which is unique in that it is built out in the water, was constructed... (read more)
