trials would evidence what we already knew to be true about the new asset. But it’s not until the tool hit the seabed, began route clearance and was tested in each mode that its capabilities were really proven.”Daniel continued, “The seabed conditions that we’ve seen here in the Baltic Sea are likely to be some of the most extreme that we’d ever work in, so it has put the PLP240 to the ultimate stress test and we’re proud to say that it’s passed with flying colors.”Lazaros Theodoridis, Cable Installation Package Manager at Vattenfall said “With the current

Linnaeus University: Seabed Pollution Helps Measure Effects of Climate Change

In a research project titled “Accumulation of metals in Baltic Sea sediment: significance for environmental surveillance and action initiatives,” scientists at Linnaeus University work to map out marine pollution, specifically methane and metals, in the seabed.The expedition, which takes place on the newly-inaugurated research vessel Svea, is led by Stockholm University and the Geological Survey of Sweden. The route begins in Norrbotten, in the far north of Sweden, and ends in Skåne, in the south, with the group making 14 sampling stops along the way. During the voyage, researchers

Kongsberg to Supply ASW Sonars for Finish Navy Corvettes

Sound Propagation Model determining the optimal tilt settings and enhancing the Probability of Detection (PoD) ratio. The SS2030 sonars will be delivered to the Finnish Navy complete with hoistable hull units and ice protection to ensure safe and efficient operation in the often harsh conditions of the Baltic Sea.The SD9500, meanwhile, is a light and compact over-the-side dipping sonar with  horizontal and vertical positioning capabilities for diver detection, ASW duties and volumetric survey assignments in shallow, reverberation-limited waters

on underwater communication and networking for UUVs.The goal of BONUS SEAMOUNT is to develop innovative autonomous vehicles and integrated sensor systems for complex real-time sea surveying, analysis and monitoring, and then to apply these in the study of submarine groundwater discharge (SGD) in the Baltic Sea. SEAMOUNT UUVs would locate and monitor SGD and associated nutrients and/or pollutants in coastal waters.Coordinated by EvoLogics, SEAMOUNT project is funded within the framework of “BONUS - Science for a better future of the Baltic Sea region”, the joint Baltic Sea research and development

MacArtney to Supply Swedish Research Vessel

this integrated system solution is the R/V Svea, a brand new research and survey vessel built at the Armon shipyard in Vigo, Spain for the Swedish University of Agricultural Sciences (SLU), and the Swedish Meteorological and Hydrological Institute (SMHI), now operating in Skagerrak, Kattegat and the Baltic Sea.  The new research vessel, constructed for a wide range of maritime research and environmental monitoring, will be used by SLU and SMHI to collect scientific data for environmental monitoring, climate research and fishing quotas. The MacArtney package will be utilized to assist in this mission

New Research Vessels Choose Scantrol

a combination of Scantrol iSYM Autotrawl and Scantrol Active Heave Compensation (AHC) systems.Scantrol recently delivered a complete package of control systems to the new Swedish oceangoing research vessel R/V Svea. The vessel is especially adapted for research and environmental monitoring in the Baltic Sea, Kattegat, Skagerak and Öresund. The vessels main activity is ecosystem investigation with a focus on recurrent monitoring of fish stocks and water quality, by the Swedish University of Agricultural Sciences and Swedish Meterological and Hydrological Institute.With Scantrol AHC the vessel

cold water temperature exchange rate. This minimises the physical impact of the insertion or extraction operation and ensures divers are able to keep fatigue to an absolute minimum.Development, testing and trials of JFD’s existing range of SDVs has taken place in the Stockholm archipelago, the Baltic Sea, Portland harbour and the waters off the west coast of Scotland. Fully tailored to customer requirements, the vehicles combine the Swedish commitment to safety-led design and the ship-building heritage of the Clyde; all underpinned by a unique operational pedigree with operator input at all stages

In carrying out the design, the key design drivers and other design issues have been scrutinized and evaluated to arrive at optimal design solutions, which prioritizes regulatory compliance, safety, and environment.The DTU Aqua operating area will primarily be the Baltic Sea, the Gulf of Bothnia, the Kattegat, the Skagerrak, the North Sea, the North Atlantic and Greenlandic waters in summer and autumn. The vessel is designed to operate world-wide including the geographical coverage area of the IMO Polar Code up till approx. 80o N depending on the ice situation.The
