Thermal Shock Technology

The objective of this project was to conduct research on the thermal effects on wells and the risk of these as related to well integrity (specifically on well barriers) and potential solutions to these risks. The contractor evaluated the effects of thermal shock on OCS well integrity and identified ways to mitigate those effects.

TAP-620-Collection and Archival of Environmental Data Relevant to Design of Arctic Structures

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:

TAP-619-An Interactive Met-Ocean Geographical Information System (GIS) with Applications for Data Query and Statistical Analysis

The objective of this project is to develop a geographical information system (GIS) for met-ocean data which allows the user to interactively query and update data.

A 2-year project is anticipated. Current funding is for first year only, and the accomplishment of the following tasks:

TAP-608-Methods to Reduce Lateral Noise Propagation from Seismic Exploration Vessels

The technical effort will focus on discovering and validating by proof-of-concept testing a reliable cost-effective method or methods and equipment to significantly reduce lateral noise in the marine environment from seismic activities and operations. This research project was conducted in two parts.

Part 1 of this project contained six tasks:

TAP-577-Design Options for Offshore Pipelines in the US Beaufort and Chukchi Seas

The objective of this study was to provide design options for Pipelines with regard to Arctic hazards such as strudel scour, upheaval buckling, and ice gouging in the Beaufort and Chukchi Seas. Design options included evaluation of PL configuration, material selection, design parameters, operating conditions, application of strain-based and limit state design methods. Design issues included construction, operations, integrity management, maintenance and intervention.

TAP-557-Numerical Modeling of Torpedo Anchors

Aimed at development and application of numerical models for the analysis of installation, behavior and strength of torpedo anchors, this Research Project will utilize and extend earlier developments at OTRC on suction caissons in clayey soils. By virtue of ease of installation, torpedo anchors have shown promise in deep-water applications. Studies will be conducted to establish the relative significance of factors affecting the performance of torpedo anchors and variants, thus contributing toward improved design of these foundations.

TAP-556-Risk Assessment of Submarine Slope Stability - Hydroplaning

Prior research on submarine slides performed by OTRC has consisted of numerical and physical modeling and the development of both empirical and numerical models to predict the initiation and movement of slides. Research shows that under certain conditions a moving slide mass can hydroplane on a layer of water that becomes trapped between the moving slide mass and the underlying soil. One of the most important aspects of hydroplaning is the interaction between the moving slide mass and surrounding fluid.
