Integrated instrumentation packages designed for operation at marine renewable energy sites have the potential to reduce the risk uncertainty around high- priority interactions between stressors and receptors. Such packages can leverage the competitive strengths of individual instruments and reduce risk in a rapid, cost-effective manner. One emerging example of environmental infrastructure to achieve these objectives, the Adaptable Monitoring Package, is presented and its capabilities described. The development and adoption of such packages requires close coordination between resource managers, technology developers, and researchers.

The Adaptable Monitoring Package (AMP), along with a remotely operated vehicle (ROV) and custom tool skid, is being developed to support near-field (≤ 10 meters) monitoring of hydrokinetic energy converters. The AMP is intended to support a wide range of environmental monitoring in harsh oceanographic conditions, at a cost in line with other aspects of technology demonstrations. This paper, which is the second in a two part series, covers the hydrodynamic analysis of the AMP and deployment ROV given the strong waves and currents that typify marine renewable energy sites. Hydrodynamic conditions from the Pacific Marine Energy Center's wave test sites (PMEC) and Admiralty Inlet, Puget Sound, Washington are considered as early adoption case studies. A methodology is presented to increase the AMP's capabilities by optimizing its drag profile through a combination of computational fluid dynamic (CFD) modeling and sub-scale experiments. Preliminary results suggest that AMP deployments should be possible in turbulent environments with a mean flow velocity up to 1 m/s.

Environmental monitoring of marine renewable energy projects is needed to reduce environmental uncertainties and en- able sustainable commercial implementations. An Adaptable Monitoring Package (AMP), along with the support infrastruc- ture required to perform maintenance of the AMP, is being de- veloped to enable real-time environmental monitoring of marine renewable energy converters. The monitoring capabilities sup- ported by the AMP include marine animal interactions with con- verters, noise levels, current and wave fields, and water qual- ity. The core instrumentation on the AMP is comprised of a hy- brid stereo-optical and acoustical camera system, a localizing hy- drophone array, acoustic Doppler current profilers and velocime- ters, a water quality sensor, cetacean click detector, and fish tag receiver. For an initial deployment to monitor a tidal turbine in deep water, the AMP is integrated into the converter structure and connected to shore via the turbine export cable, but can be dis- connected and recovered for maintenance independently of the turbine. The AMP is deployed by a SeaEye Falcon inspection- class ROV and a custom tool skid. This paper describes the func- tion, design, and dynamic stability of the AMP and deployment ROV. The conceptual design and approach to operations, to be confirmed through field testing, suggests that the AMP is likely to meet the need for high-bandwidth monitoring of marine re- newable energy converters at an acceptable cost.

The Adaptable Monitoring Package (AMP) along with a Remotely Operated Vehicle (ROV) and custom tool skid, is being developed to support near-field (󖼚 meters) and long-range monitoring of hydrokinetic energy converters. The goal for the AMP is to develop a system capable of supporting a wide range of environmental monitoring in harsh oceanographic conditions, at a cost in line with other aspects of technology demonstrations. This paper presents a system description of all related infrastructure for the AMP, including supported instrumentation, deployment ROV and tool skid, launch platform, and docking station. Design requirements are driven by the monitoring instrumentation and the strong waves and currents that typify marine renewable energy sites. Hydrodynamic conditions from the Pacific Marine Energy Centers wave test sites and Admiralty Inlet, Puget Sound, Washington are considered in the design as early adoption case studies. A methodology is presented to increase the capabilities to deploy and operate the AMP in strong currents by augmenting thrust and optimizing the system drag profile through computational fluid dynamic modeling. Preliminary results suggest that the AMP should be deployable in turbulent environments with mean flow velocities up to 1 m/s.
