Did you know that we are already building the second Cable line in the Small Strait in Estonia? 🧐 The second 110-kilovolt cable line in the Small Strait will connect the overhead power line that ends on the west coast of Muhu island with the Orissaare substation in Saaremaa. The project is on commission from Elering The new submarine cable will have a total length of 6.9 km of which 5,2 km will be offshore. The total weight of the cable is 390 tonnes and will have the capacity of 520 amperes. The submarine cable is manufactured in Finland by Prysmian Group’s Pikkala Factory. The construction of the project will be divided to 3 phases: 📍 The first phase consist of the pipeline excavation and laying the underground cables onshore. 📍 The second phase will carry out the excavation work in the Small Strait storage area and cable will be laid in the sea. 📍 The third and final phase of the project will involve the dismantling of an 110 kV high-voltage overhead line on the Väinatamm. The first 110-kilovolt cable in the Small Strait was laid at the end of 2019. Current construction of a second submarine cable through the Small Strait will significantly improve the islands’ security of electricity supply and the possibility of connecting new renewable energy generation capacity. In addition to that, Väinatamm, will become safer for birds to ensure the safety of wildlife in the area. PS: In the video below, you can see the construction of the first cable in the Small Strait 🤩 #connecto #electricity #innovation  

Experimental investigation of two shared mooring configurations for a dual-spar floating offshore wind farm in irregular waves. Paper by Guodong Liang (Department of Engineering Sciences, University of Agder (UiA); Tomás Lopez Olocco (CEHINAV), Antonio Medina Mánuel (CEHINAV), Leandro Saavedra Ynocente (Canal de Experiencias Hidrodinámicas de El Pardo (INTA/CEHIPAR), Antonio Souto-Iglesias (CEHINAV), Zhiyu Jiang (Department of Engineering Sciences, University of Agder (UiA) Marine Structures, Volume 95, 2024, 103579. ISSN 0951-8339. https://lnkd.in/eXfxF_zd Abstract: Shared mooring brings potential cost benefits to a floating wind farm. In such a wind farm, adjacent floaters are connected by shared lines and the total number of mooring lines is reduced. This paper presents an experimental study on a dual-spar floating offshore wind farm. In the first configuration, two spars are connected by a shared line. In the second configuration, a clump weight is added to the shared line. Irregular wave tests are performed for both configurations under operational and extreme wave conditions. The platform motions of one wind turbine and the mooring tension are measured during the tests. The influence of the added clump weight is found to be insignificant in the operational wave conditions. Under extreme waves, the added clump weight results in smaller platform motions in the wave direction and reduced tension oscillations in all mooring lines. With the additional clump weight, the extreme mooring tension in the shared line can decrease by 30% and fewer snap loading events occur, but the extreme tension in single lines can increase by 6%. This study contributes to an improved understanding of shared mooring systems and facilitates the development of model test methods for floating wind farms. #etsinavales #somosupm #cehinav #cehipar #uiagder #sharedmooring #clumpweight #hydrodynamicmodeltest #sparfloater #floatingwindfarm

Due to the recent tendency of the offshore wind industry to install wind farms in deep waters, novel mooring solutions to reduce costs, such as shared mooring systems configurations, have gained interest in the offshore wind sector. Last year our director Antonio Souto-Iglesias and our research team Tomás Lopez Olocco and Antonio Medina Mánuel, designed, constructed, and tested a couple of model-scaled OC3-Hywind spar platforms with a shared mooring system. The results of this joint project with researchers from University of Agder (UiA), Guodong Liang and Zhiyu Jiang, and #CEHIPAR ocean basin of Instituto Nacional de Técnica Aeroespacial «Esteban Terradas», Leandro Saavedra Ynocente can be found here: https://lnkd.in/d9374ta5 This study aimed to establish the multi-body dynamic behavior of the floating wind farm with a shared mooring and analyze the influence of adding a clumped weight. In this work, we study both mooring configurations under different operational and extreme sea states. Hopefully, these promising and novel results will help the offshore wind industry better understand the multi-body dynamics of this promising cost-efficient mooring solution: the shared mooring systems. We'll keep you posted with more results of our future exciting experimental campaigns! #research #offshorewind #floatingwind #windturbine #netzero #fowt #renewables #mooring #shared #sharedmooring #NREL #OC3 #UniversityofAdger #CEHINAV #CEHIPAR

Silvasti TCI- project of building 30 new WTG’s in Northern Finland has moved to transport phase.   Taking full advantage of Silvasti’s specialized fleet designed for large diameter tower sections and other wind power components, the amount of needed road modifications along the transport route have been kept to a bare minimum. As an example, the state of the art tower adapters eliminate the need to remove overhead portals, which in many cases have to be dismantled from the way of larger special transports. The effects of the transports are less prevalent to the public, when less route modifications are needed. #Silvasti #ForYourSpecialCargo #WindPower #TCI

🔔 It´s official: Draugen is ready for 2040! Field life extension is an excellent way of maximising our resources and creating high value from existing infrastructure. Our first own-operated asset, Draugen, has outlasted most expectations for three remarkable decades. ❓Did you know that: When Draugen came on stream on October 19, 1993, the projections were clear – production would cease around 2013 ❗ However, technological advancements combined with industry expertise have demonstrated the potential of the Draugen field. On Friday, March 8th, the Norwegian Ministry of Energy approved the extension of Draugen until December 31, 2040👏👏👏 “This is the result of several years of work on extending the lifespan of Draugen, which has involved all parts of the OKEA organisation. We will continue to invest in new technologies, new ways of working, and, last but not least, new projects. The future for Draugen is promising”, says Kirsti Berg Flatval, Asset Manager for Draugen. The conditions for approval include preparing a report on the possibilities for EOR (Enhanced Oil Recovery) measures on Draugen, as well as ensuring resource management for the potential satellites, Springmus East and Garn West South, in addition to maturing other prospective areas, together with our license partners. With this, the Draugen story of performance, progress, and promise continues📈 Petoro M Vest Energy AS #operationalexcellence

Silvasti’s TCI-project of building 30 WTG’s in Northern Finland is progressing on schedule. The site roads and hardstands are seeing increased use, as component transports are arriving to the site at a steady pace, while other site operations are on-going at the same time.   The innovative delivery and lifting plan has made it possible to thoroughly optimize the hardstand areas and site roads, to ensure the best possible project performance. Thanks to the efforts of the whole project team, we have been able to achieve significant reduction in the size of the hardstands, without any compromises to the safety, efficiency or usability of the area. Additionally, the in-depth planning has enabled optimization of the site roads.   The optimization of the site infrastructure and delivery planning has resulted in significant cost savings, as well as a substantially smaller environmental impacts from the project.   #Silvasti #TCI #WindPower Ilmatar Vestas Global Wind Service BMS HEAVY CRANES MSA Construction Denmark
