Environmental Impact Assessment

The infrastructure plans, physical climate, biological environment, and human activity implications must be evaluated for the entire life cycle of the Offsh2re Shetland, including decommissioning. The schematic below depicts the components of the planned project.

A baseline risk evaluation has been proposed for the project's marine and onshore stages, which include subsea cabling and shoreline transfer for the offshore phase and underground cable from the shoreline and the sub-station/control building for the onshore phase[7],[8]. The baseline risk assessment is a compilation of impacts previously addressed in environmental scoping assessments pertaining to the Hornsea 4 and Beatrice decommissioning[7],[8].

 

Introduction

​

When constructing new Offsh2re Shetland substructures, the ability to consider and quantify risk (either qualitatively or quantitatively) is critical[1]. The risk management process should provide a thorough understanding of the possible risks associated with the specification, build, implementation, service, and decommissioning of new substructures[2],[3].

To date, risk assessment has been performed using various generic risk  assessment  guidelines  and  standards. While these recommendations have an overarching framework and direction for risk management, they lack adequate clarity and cohesion to determine risk associated with innovative substructures[1]. To address this, a risk management approach based on the study Qualifications of advanced infrastructure for wind turbines 10MW and water depths greater than 50m[5].

 

Risk Assessment and Management

​

Because of all external forces and the essence of their processes, the practices of all types of organizations are vulnerable to possible hazards[1]. A theoretical collection of exercises designed to classify, analyze, and quantify possible threats may be used to determine risk[3]. Risks can be handled by defining steps to be taken to minimize or handle the cause or effect of the danger, and they can be embraced until the risk is As Low as Reasonably Practical[4].

 

Risks can also be deemed appropriate if they are seen as an intrinsic or necessary component of the technology creation process[4]. Identifying Risks Danger sources or hazards are components that, individually or in combination, have the inherent potential to cause risk[4]. To ensure that all possible causes of risk and hazards are detected, a comprehensive approach to identifying these is needed[2]. The Offsh2re Shetland team followed the evaluation of a quality methodology, where the risks are identified based on discussion and exchange of views, always according to corresponding and official publications with similar content.

 

 

Assessment of Consequence and Probability

​

For the purposes of risk management, both outcome and likelihood are usually calculated on a 5-point scale. The particular type of harm associated with the points on this scale can vary based on the type of risk assessment being performed. The probability of occurrence and the result of the danger can be integrated into a matrix structure to allow for an overall risk assessment[1].

The risk matrix enables prioritisation for risk avoidance of risks with a high likelihood and effect[6]. The risk matrix method also allows for the assignment of a final risk score to each of the hazards by integrating the likelihood and outcome ratings, resulting in a manageable number of categories despite disparate sources of risk[6].

Risk analyses should be revisited on a regular basis to ensure that conditions that change over time do not have an adverse impact on the risk of the framework under consideration[6]. This is especially important during periods of abrupt or dramatic transition, such as during the technological growth phase[6].

​

Manufacturing / Commercialization

The aim of the manufacturing risk assessment is to detect and evaluate any manufacturing-related hazards, such as expense, timetable, and quality[4]. Manufacturing risks should be evaluated alongside the Manufacturing Readiness Level (MRL) metric[2]. Commercialization risk covers those aspects of risk related to bringing a new product to market, including non-technological  considerations  such  as  regulatory  environment,  financial  performance  and  proposition, and  market  opportunities aspects[2],[4]. As a result, this phase is taken to mean an evaluation of commercialization risk and potential, as both risks and strengths can be found[3],[7].

​

Marine / Land

​

The environmental effects on the aquatic ecosystem are depicted. Noise is the most serious problem in the human world[2],[7]. The key causes of noise associated with site planning and unit operation are largely comparable to those associated with decommissioning and those hypothesized to be associated with Offsh2re Shetland building[2]. Shipping, machinery, dredging, and pile driving, or drilling are descriptions of these[3],[8].

 

Conclusion

​

These risks associated with the Offsh2re Shetland project architecture can be detected, assessed, measured, and resolved in a timely manner by using and adapting the risk management approach. When used as part of a comprehensive risk assessment procedure. Although the risk management approach proposed was created to evaluate the Offsh2re Shetland project. The procedure was applied in accordance with the community risk management and a series of stormy proposals for the project's undeniable progress in a mix of 'green companies' that value the environment[6],[8].
