The purpose of this Research Project is to monitor the structural health of the BIWF, thereby gaining insight into the structural response of the system for validating design assumptions in BSEE’s plan review and oversight functions.
Test Effort: Analysis of the Efficacy of Conventional Sorbent Materials Exposed to Selected Categories of Dielectric Fluids
This new project will test Type I sorbents efficacy when exposed to three - (3) categories of Dielectric fluids. These will include natural ester, synthetic ester, and mineral oil (hydrocarbon) based fluids. The work will be performed at Ohmsett with testing completed to BSEE Oil Spill Research and Response (OSRR) project specifications. It will compare the findings to a selected control conventional oil product and will provide performance data to stakeholders to facilitate decision making for oil spill preparedness and response operations.
The purpose of this study is to evaluate the available options for conducting remote inspections on offshore wind turbines (above and below the water line) by; identifying commercially available technologies can be used for remote inspections, maintenance, testing, and repair; determining the types of inspections, testing, maintenance, and repairs that can be conducted remotely, developing a list of the critical components that can be inspected, tested maintained and/or repaired through remote capabilities; identify current and future remote capabilities; and identify best practices for doc
The purpose of this study is to evaluate the available options and performance of both passive and active fire protection and fire suppression systems. This study will conduct a global review of current industry-standard systems and research other options not currently used by the offshore wind industry. The project includes an assessment of:
To compare partially and fully coupled dynamic analyses of offshore wind turbines.
Offshore wind turbines are designed and analyzed using simulation methods (computer codes) capable of predicting the coupled dynamic loads and responses of the systems. A partially coupled analysis using load exchange may be desirable due to intellectual property rights issues between designers of the various components. The validity of this partially coupled analysis method should be investigated for offshore wind turbines with various types of foundations.
The guidelines for structural health monitoring will be based on the experience from various long term monitoring schemes conducted in Europe for offshore wind turbine foundations and other platform structures within the more mature offshore oil and gas industry. The guidelines will be organized by monitoring topics relevant for different types of foundations including monopiles, pre-piled jackets, bucket and gravity base foundations and anchored floaters, recommended arrangement for monitoring systems will be described for each topic.
The goal of this proposed work is to develop superior methods for determining the onset of breaking waves and their impact loads on offshore support structures for wind turbines in shallow waters, using high-fidelity CFD simulations. To accomplish this goal, we will partner with Fishermen's Energy LLC, who will provide metocean data and structural models that will inform our activities. We will examine breaking wave conditions in the U.S. for proposed offshore wind turbine support structures.
The objective of this project is to evaluate the suitability of existing guidance for the design oflaterally-loaded monopiles and to provide recommendations for improving design methods.
The objectives of this project are the following:
This study aims to: (a) Evaluate fatigue design criteria for offshore wind turbine support structures; (b) Study fatigue design methodologies applicable to complex fixed and floating offshore wind turbine support structures; and (c) Recommend a rational, practical, fatigue design method for offshore wind turbine support structures.
