MHK Content Models
The U.S. Department of Energy (DOE) has created the Marine and Hydrokinetic Data Repository (MHKDR) to help accelerate the advancement of marine renewable energy technologies. The MHKDR is designed to efficiently collect, store and appropriately disseminate the wealth of valuable information generated from DOE funded and other MHK projects. Benefits will span from focused technology development to broad industry evaluation. Performance trending, resource maps, technology gap identification, lessons learned, and cost analysis are, for example, a few areas that will directly benefit. Decision makers, investors and the MHK community will also have access to information to support decision-making.
The MHKDR strives to:- enable easy data upload process to help with data reporting requirements
- provide a curation process to allow internal data experts to help evaluate the quality of the data
- keep secure data secure (based on moratorium dates)
- securely share data with DOE and national laboratories
- share unrestricted data openly
Data to be collected may include field and laboratory measurements, costs, project reports, and video. Content models are tools used to collect a subset of common data in a structured form that allows quick data aggregation between projects. These spreadsheets organize the data in a consistent manner, using standardized units, thereby allowing straightforward assessment and use. The content models are organized by task — i.e., field testing, component development, LCOE, etc.
This effort's success requires the community's engagement in maintaining relevance and a user audience to realize the value of the databases and tools. Feedback for improvement is welcome. Please . The MHKDR is powered by OpenEI.org, an energy information portal sponsored by the DOE and developed by NREL in support of the Open Government Initiative to make energy data transparent, participatory, and collaborative.
CEC Field Testing
version 2.1
downloadThe Current Energy Converter (CEC: tidal, river and open-ocean) Field Test Content Model provides data submitters with a straight forward and consistent means of uploading some processed field test data and associated metadata to the MHK data repository. These data are important to DOE and will be used to develop data products that provide quantitative information to guide and support programmatic decisions. Data will also be used to assess the state of the MHK industry and technology readiness, perform resource assessment, and support DOE national laboratory research. The ultimate goal is to use these data to perform research and tailor programs to best benefit the industry.
The metadata are static information describing the project, the CEC technology under test, and the test setup. These metadata provide critical contextual data that are needed to understand the test and interpret the test data. Field test data are time series of the average operating environmental conditions and device performance averaged over a measurement duration of at least 20 minutes. These data should be provided continuously over the test duration, even while the device is not operating. Where possible, data should adhere to IEC and NDBC definitions as outlined in the spreadsheet. Please strictly adhere to the units to ensure consistency between all submissions.

The metadata are static information describing the project, the CEC technology under test, and the test setup. These metadata provide critical contextual data that are needed to understand the test and interpret the test data. For runs with constant flow characteristics, a single entry should be provided for each test and include the average flow conditions and device performance that are calculated over valid times within each run, after steady state has been reached. For longer tests or test with changing conditions, separate entries should be provided for each wave condition/sea state. Where possible, data should adhere to IEC and NDBC definitions outlined in the spreadsheet. Please strictly adhere to the units to ensure consistency between all submissions.

version 1.0
downloadThe MHK Wear and Failure Content Model provides data submitters with a straight forward and consistent means of uploading data pertaining to the wear and failure of MHK components and associated metadata to the MHK data repository. The intent of this content model is to collect data from across the MHK industry so comprehensive sets of information on wear and failure can be compiled and analyzed. Based on these data, industry can learn about common causes/results of failures and identify conditions where device wear and/or failures are most likely to take place. These data are important to industry, because it may enable new designs and help improve overall device and system quality. Data will also be useful to DOE and others in understanding wear and failure issues, which may help shape program goals and decisions in the future.
