On the convention in Dreverna – additionally concerning the analysis of the offshore wind energy park

The convention “Sea and Coastal Analysis” is organized by the Maritime Analysis Institute of Klaipėda College.

In Dreverna, Could 15-17. The convention “Sea and Coastal Analysis” organized by Klaipėda College’s Maritime Analysis Institute is going down, meant for Lithuanian researchers, representatives of enterprise and business, and the general public sector, searching for to share analysis outcomes, good examples of science and enterprise cooperation, and different present points.
On the convention on Could 16 the worldwide inexperienced vitality firm “Ignitis renewables” along with its accomplice “Fugro” introduced seabed analysis knowledge to the nation’s scientific group. These knowledge have been collected whereas the corporate was getting ready to construct an offshore wind farm within the Baltic Sea, off the coast of Lithuania.
On the convention, Anne Marie Roikjær introduced Ignitis Renewables’ first offshore wind farm; Dennis Heuckelbach mentioned the outcomes of the exploratory geophysical surveys within the space of ​​the deliberate park; Dr. Giedrė Godienė spoke concerning the methodological features of assessing the visible affect of offshore wind farms on the panorama; Artūras Razinkovas-Baziukas learn the report “Modern technical options to harmonize the event of renewable vitality sources within the sea with environmental safety – NID4OCEAN venture”.
Offshore wind parks in Lithuania are one of many nation’s most vital vitality independence tasks. They may considerably improve the manufacturing of electrical energy from renewable vitality sources and thus cut back Lithuania’s dependence on electrical energy imports and guarantee low electrical energy costs for residents.
The worldwide inexperienced vitality firm “Ignitis renewables” is getting ready to construct the nation’s first offshore wind farm within the Baltic Sea and, in accordance with the stipulated necessities, has ready an environmental affect evaluation program for this extraordinarily vital vitality venture for Lithuania. In response to A. Roikjær, venture supervisor of the offshore wind farm, inexperienced vitality is intently associated to nature and its preservation, and the safety of the Baltic Sea ecosystem is likely one of the most vital objectives of the corporate’s sustainability technique.
“Whereas growing renewable vitality tasks, we inevitably have an effect on the surroundings, however with the intention to guarantee a steadiness between clear electrical energy manufacturing and nature safety, we’ll take all mandatory measures to attenuate the affect of the offshore wind farm on the surroundings, and when it’s unattainable to keep away from the affect, we’ll implement compensatory measures that enhance the state of the surroundings measures”, says A. Roikjær.
In response to the venture supervisor, throughout the whole growth interval of the offshore wind energy park, good worldwide practices will probably be relied upon – extremely certified specialists and consultants from Lithuania and different international locations will probably be consulted, who will convey their expertise and information to the venture in Lithuania. It’s aimed that the environmental affect evaluation and procedures of this venture meet not solely Lithuanian, but additionally the very best European and worldwide necessities.
To start with, it’s mandatory to find out and assess the affect of the deliberate wind farm on particular person parts of the surroundings, ie the floor of the earth and its depths, air, water, panorama and organic variety, and so forth.
“Ignitis renewables” has signed a contract with “Fugro” for the primary geophysical survey of the territory of the Lithuanian offshore wind farm. It’s stated that that is a particularly vital stage within the growth of the venture, as a result of these research will assist to raised assess the situations of the Baltic seabed, resolve the place the wind farms will probably be constructed, and make selections associated to their building and design.
Fugro’s geophysical survey vessel, Fugro Frontier, is already investigating the 120 sq. kilometer offshore wind farm space within the Baltic Sea, accumulating two-dimensional ultra-high-resolution underwater knowledge, in addition to bathymetric, side-scan sonar and magnetometric knowledge.

A park of offshore wind energy vegetation is deliberate within the Baltic Sea, for which the realm of ​​the deliberate territory within the Baltic Sea reaches about 120 sq. kilometers, the park territory is not less than 36 kilometers away from the coast, the gap to Klaipėda seaport is about 60 km. Its depth ranges from 28 to 48 meters, and the whole space falls inside the zone of 9-10 m/s annual common wind velocity. The attainable variety of wind energy vegetation will attain as much as 55, their most top is as much as 350 meters.

It’s deliberate that in 2028, two offshore wind parks with a capability of roughly 1.4 GW, which is able to begin working within the Baltic Sea a part of the unique financial zone of the Republic of Lithuania close to Palanga, will produce as much as 6 TWh of inexperienced electrical energy per 12 months, which might guarantee as much as half of Lithuania’s present electrical energy demand, in addition to will entice virtually 3 billion EUR investments and can create not less than 1.3 thousand new jobs.
