Specific objectives of this report were: Compare and contrast the risks and benefits of using stiffer synthetic fibers vs. polyester fibers for mooring rope design, manufacturing, installation and long-term operations over the last decade in the Gulf of Mexico.
By theoretical analysis, compare dynamic responses of typical floaters moored with polyester segments and with stiffer fiber segments.
The objective of this project was to provide a description of wave and current energy generating device systems and subsystems and provide a functional taxonomy; identify criteria pertinent to the design, construction, installation, maintenance and operations of these systems, and review the criteria to determine applicability, adequacy, and suitability; identify existing codes and standards that can be applied to these devices; conduct a regulatory gap analysis; and recommend regulatory initiatives or approaches for addressing identified deficiencies.
Free Flow Energy performed a gap analysis to determine if modifications should be made to engineering specifications and regulatory standards to enable the placement of wave and current energy devices within the outer continental shelf (OCS) without compromising safety and performance guidelines.
The following tasks were accomplished:
Task 1. Acquire basic engineering information and generate a list of engineering concerns.
Task 2. Address safety and regulatory concerns and generate a checklist for the complete spectrum of unique safety concerns.
The project developed preliminary guideline Integrity Management (IM) procedures for offshore wind turbine facilities appropriate for use in US waters. These procedures include guidance on frequency and method of inspection and address the platform structure, turbine tower, turbine and housing, and turbine blades.
During the 1980s the probability of impact by an extreme ice feature, or EIF, that would generate extreme loads on a production platform in the Southern Beaufort Sea, was identified as a key design criterion. In recent years the effects of climate change on the arctic climate and ice cover has received increasing attention. The changing climate already appears to be contributing to the deterioration of the ice shelves of the western Arctic Islands with the increased calving of ice islands (II).
The objective of this study was to assess the presence and condition of marine growth on floating facility riser systems in the Gulf of Mexico and practices used for inspection, removal and mitigation.
The primary objectives of this project are to (1) consider the full suite of environmental data (meteorological and oceanographic) and structural performance data that could be collected during exploration and production operations off the coast of Alaska, and review each type of measurement in terms of its potential value to the design of future offshore infrastructure; and (2) assess alternatives and develop a recommendation for how MMS should go about collecting, archiving and processing this data.
The project will be accomplished via the following tasks:
The objectives of the JIP is to expedite the publication of the updated ISO 13628-12 and update of API RP2RD, working in conjunction with the existing joint ISO/API Task Group and Chairman.
The objectives of this project were to identify and analyze the factors that may contribute to the apparent conservatism in fixed-structure foundation design and to provide guidance on how to incorporate this information into design standards. The research consisted of four tasks:
Task 1. Qualitative Analysis: Compile, analyze and summarize available data for platforms where the foundation unexpectedly survived hurricane loading in Andrew, Lili, Ivan, Katrina, or Rita.
The objective of this study was to: Extend the database of wave statistics,
Capture storm and loop current events and analyze TLP response to these events,
Assess occurrence of riser and tendon VIV events.
This study served to provide a two-year extension of work initiated under TAR Study 564 and included:
