        波兰奥伦能源公司位于波罗的海的Baltic East海上风电场场址已完成海底初步勘测。该海域的海底地震及地质技术初步调查工作已全部结束。

 

        风电场开发商奥伦集团表示，Baltic East项目的海底初步勘测于6月底启动，持续逾15周。勘测数据及后续分析将助力实现两项关键目标：精准解读海域地质构造，以及编制设计工作必备文件和后续地质勘察行动计划。

 

        奥伦集团董事会主席雅努什·比尔强调："海底勘测是海上风电项目建设的关键环节。本次波罗的海勘测由三家波兰企业组成的联合体执行，彰显了波兰供应链为海上风电领域提供优质服务的强劲意愿。"

 

        其中，托伦地球物理公司承担了二维多通道地震勘测任务。后续数据分析将聚焦两个维度：初步识别地层结构，研判潜在地质灾害（如巨砾区或浅层天然气藏）。未爆炸物勘测工作由MEWO公司实施，旨在评估工勘区域海底的危险物体洁净度，期间成功识别数十处磁性异常点。

 

        野外研究的收官环节由奥伦石油波罗的海公司依托"西鲁尔"号作业船完成。累计钻井深度超1200米，最大钻探深度达海底以下80米。目前实验室正双线推进：一方面对采集的土壤样本进行分析，同时开展地震数据解译工作。

 

        开发商已为这座1吉瓦装机容量的海上风电场取得关键施工许可及初步电网接入条件。据奥伦集团测算，项目全容量投产后，生产的清洁电力可满足约125万户家庭用电需求。

Preliminary seismic and geotechnical surveys of the seabed have been completed at the Baltic East offshore wind farm site in the Polish Baltic Sea.

 

Preliminary seabed surveys for the Baltic East project began at the end of June and lasted over 15 weeks, said Orlen Group, the developer of the offshore wind farm.

 

The surveys and subsequent analysis will enable accurate interpretation of the seabed’s geological structure at the offshore site, as well as the development of documentation necessary for design work and an action plan for subsequent geological campaigns.

 

“Seabed surveys are one of the key stages in the implementation of our offshore wind farm project. The work in the Baltic Sea was carried out by a consortium of three Polish companies, demonstrating the growing willingness of the Polish supply chain to provide high-quality services for the offshore wind energy sector,” said Janusz Bil, President of the Management Board of Orlen Group.

 

Geofizyka Toruń conducted the 2D multichannel seismic survey. Subsequent analysis of the collected data will focus on preliminary identification of ground layers and interpretation of potential geological hazards, such as boulder fields or shallow gas deposits. 

 

UXO surveys, or searches for potential unexploded ordnance, were carried out by MEWO. They enabled the assessment of the seabed’s cleanliness for hazardous objects at the geotechnical survey site. Dozens of magnetic anomalies were identified.

 

The final stage of field research was conducted by ORLEN Petrobaltic using the Silur vessel. A total of over 1,200 meters of drilling was performed, reaching depths of up to 80 meters below the seabed. Laboratory work on the collected soil samples and interpretation of the seismic results are currently underway.

 

The developer secured the key construction permits as well as the preliminary grid connection conditions for the 1 GW Baltic East offshore wind farm. Once fully operational, the project will supply enough renewable energy for approximately 1.25 million homes, according to Orlen.
