Upload by Mali

Sunrise Wind’s WTG monopile foundation pile-driving monitoring plan outlines permitting and agreement context, defines monitoring zones, and describes the monopile system and pile-driving sequence. It presents mitigation and monitoring measures, including visual monitoring distances, clearance, soft-start, shutdown, pauses and silent periods, and post-piling monitoring. The plan specifies daytime and nighttime monitoring approaches, data collection, PSO communication, noise abatement system requirements, and reporting workflows for training and protected-species and vessel-strike incidents, including North Atlantic right whale and injured or dead species.

FAQs

What does the plan define about monitoring zones?

The plan includes a section that defines mitigation and monitoring zones to guide where monitoring and mitigation actions apply during pile driving.

What monitoring actions are required during different operational states?

It specifies measures for clearance protocols, soft-start protocols, shutdown protocols, pauses and silent periods, and post-piling monitoring, along with daytime and nighttime monitoring plans.

How does reporting work for protected species and vessel strikes?

The plan provides reporting sections that cover training responsibilities and incident reporting workflows, including vessel strike reporting and protected-species reporting such as North Atlantic right whale encounters and injured or dead protected species.
