Offshore wind consultancy firm OWC has identified geohazards that developers should address, following a study of the geological conditions of the Polish sector of the Baltic Sea.  

The findings of the study will be presented at an OWC-hosted webinar on 4 November 2020, with the full report being published a week later on 11 November 2020.

“We have identified numerous key potential geohazards such as boulders, shallow gas, geological faults, chalk and lateral variability of the soil conditions with some bedrock depth uncertainty. These are key hazards that developers should build into their site condition evaluations of prospective projects,”
said Łukasz Sikorski, head of OWC in Poland.

Overall, offshore Poland is covered by various kinds of sediments, ranging from loam through fine grained sand and coarse sands, to gravel and stones, with sediment thickness varying between 50 and 100 metres.

“Although Poland can benefit significantly from a well-established local construction industry that is more than capable of producing foundations such as monopiles and piles, the geology expected at the Polish Baltic Sea areas indicates that the type of turbine foundations to be used here should be carefully assessed,”
added Sikorski.

In its National Energy and Climate Plan (NECP) Poland identified offshore wind as one of key technologies to meet its goals for renewable energy for 2030. It is also a strategic project in the draft of Poland’s Energy Policy until 2040. It will help to diversify the Polish national power generation structure that today heavily depends on coal.

The country plans to install around 5.9 GW of offshore wind energy by 2030, and is working on a maritime spatial plan that is intended to add additional area for offshore licensing.
