Update of reliability, Health & Safety and Environmental Assessment

This intermediate report will update the initial report with detailed identification of hazards and potential failure modes, identifying health & safety and environmental considerations. This will be issued in M15, just before the assembly, installation and testing. INTECSEA will lead the reliability and H&S aspects while PLOCAN will lead the environmental aspects. Intermediate deliverable of the tasks 6.1 (Hazard & Reliability Aspects), task 6.2 (H&S aspects) and Task 6.3 (environmental aspects). A final deliverable report will be submitted in M33 gathering all data produced along the reliability, Health & Safety and Environmental Assessment, conducted throughout the different phases of the project.

Preliminary design for 10-20MW systems

This report will provide a preliminary design of the PivotBuoy for largescale 1020MW floating systems based on the updated design carried out on task 25 and simulations done in WP5 It will also bring the learning and experience gained during the design of the partscale prototype manufacturing assembly and installation into the new optimized designRefers to task 25

Initial Project Risk Management Plan

A project risk management plan will be created at the start of the project and updated periodically along the project including risk identification, risk qualification / quantification, risk response planning. Refers to task 1.4.

Socio-economic impact and LCA assessment

This report will summarise the potential impact of PivotBuoy technology though the whole life cycle of a project performing a LCA analysis and also impact on the local economy in terms of potential job creation local value etc Refers to task 73

Final performance assessment (operational regime and under extreme sea conditions) & model validation

This deliverable will include the validation of the numerical models with experimental data from the 13 tests at sea Comparison between numerical results to the experimental data eg motions loads turbine behaviour etc will be performed to validate and finetune the numerical simulation modelsRefers to task 55

Final Reliability, Health & Safety and Environmental Assessment of PivotBuoy system

This final report issued in M33 just after the decommissioning will update the previous report with the results regarding reliability aspects identification of hazards and potential failure modes and corrective actions health safety and environmental considerations during the manufacturing assembly installation and testingINTECSEA will lead the reliability and HS aspects while PLOCAN will lead the environmental aspectsIt is the final deliverable of the tasks 61 Hazard Reliability Aspects task 62 HS aspects and Task 63 environmental aspects

Project videos

A video will be produced to present the final project results to the interested public In M12 WAVEC will produce a first video introducing the technology goals challenges and deliverablesRefers to task 85

End of Project workshop

Engagement event with target stakeholders summarising and profiling the PivotBuoy project The final report will also summarise the general outcomes of the Stakeholder consultation meetingsRefers to task 84

Project website

Launch of the project’s website which will be the central communication tool during the project. Refers to task 8.2.

Techno-economic model

This deliverable will include a report describing the techno-economic model which will be built for the assessment of PivotBuoy concept. Refers to task 7.1

Identification of failure modes and initial reliability, Health & Safety and Environmental Assessment of the PivotBuoy System

A preliminary report with the initial Hazard Idenfication (HAZID) and potential failure modes. It will also include initial Health & Safety and environmental considerations to make sure this important aspects are considered early in the design process. INTECSEA will lead the reliability and H&S aspects while PLOCAN will lead the environmental aspects. It is the initial deliverable of the tasks 6.1 (Hazard & Reliability Aspects), task 6.2 (H&S aspects) and Task 6.3 (environmental aspects). An intermediate report will be issued in M15, prior to the assembly and installation to update the initial assessment.
