This project will survey and document The objective of this project is to verify the laboratory results in a simulated downhole environment (i.e. with an actual fluid pressure gradient from surface).
Wax precipitation, wax deposition, hydrate formation, and hydrate deposition are expected to occur concurrently in long distance tiebacks transporting waxy oils or waxy condensates. Little is known about interactions between wax and hydrates in these systems and any impacts (positive and negative) of wax on hydrate phenomena and transportability. This project aims to conduct exploratory work at a benchtop level to study such interactions.
Diagnostic technologies play an integral role in the deposit removal process by providing the means for characterizing a plug. Characterization of the deposit involves obtaining pertinent information about the deposit including but not limited to the type of solid, type of deposit (plug vs restriction), location and length.
Deposition in Gas-Filled Deadlegs
Measure and characterize the hydrate deposition in deadlegs as a function of the insulation on the deadleg and the header temperature.
Develop design and operating principles based on the measured data.
Thermoplastic composite pipe (TCP) is gaining traction within the deep-water arena. To date, the two vendors have supplied pipe for temporary commissioning lines and jumpers. The purpose of this project is to develop configurations and costing for deep-water dynamic applications.
To provide a global Standard for Subsea docking station to allow all solution providers to successfully interface to infrastructure installed subsea. Standard is to include references to current SWiG work in defining the standard for Inductive Coupling (Power and Communications). Standard is to not restrict currently available vehicles and capability. Some work has been done as part of Deepstar in the past, this work shall update and finalize this standard.
Establish feasibility and understand barriers to extending the technology to larger and longer flowlines, including design, manufacture and installation. Description and discussion of the technical and/or commercial barriers and requirements for progressing Airborne’s TCP technology to larger internal diameters, and the work, schedule and resources required to address these barriers.
It is anticipated that real-time condition monitoring and partial stroke testing would exceed the availability validation capability of the current spring based systems. The objective of the proposed project would be to quantify this improvement and demonstrate the reliability of the power delivery system (batteries).
Validation of AUV capability for autonomous subsea leak detection
Define a clear overview and break down of cost component for an installed flowline, at different levels of granularity (procurement, engineering, material, isolation, installation, opex). Map the different steps that can be taken to lower the cost, in term of new technology, design, requirements and practices.
Functional Specification for In-Situ Riser Inspection Tools
Develop a functional specification for an In-Situ Riser Inspection tool for development by industry.
Measurement from Fixed and Floating Facilities
Develop and test prototype of imaging-based above-water platform-mounted system that can accurately and reliably measure surface currents from fixed and floating facilities 24/7, avoiding the need for in-water / submerged installations
Management of Offshore facilities
Objective of this project is to establish a high level guideline that defines minimum requirements to ensure consistency and compatibility of data as an enabler for efficient life cycle management over all phases of the asset development (design/construction/operation).
This project will survey and document new BOP technology and capability for shearing within the industry.
Development of hydrate blockage remediation tool for “difficult” shaped subsea hardware e.g. trees / manifolds / jumpers.
Completion fluids used in deepwater wells must be properly formulated to prevent formation of hydrates. Completion fluids could be brines or blends of brines and organic hydrate inhibitors (e.g., MEG or methanol). Reliable predictions for hydrate equilibrium conditions ae important to developing/ selecting the proper completion brine.
for LDHIs using Rock-Flow Cell
To advance the testing methodology and bridge the gap between the lab and field conditions, the recently developed rock-flow cell allows a more rigorous and representative test for LDHIs as it captures the shear and phases dispersion at the conditions that would be actually encountered in the field in terms of liquid loading, water cut, and GOR.
Subsea production systems require both continuous and intermittent injection of chemicals to support their day to day operations. Subsea chemical storage and injection is one opportunity to reduce initial field development costs, allow additional wells to be tied in beyond what was originally planned, or to supplement the umbilical in the event it is damaged.
Perform an investigation to determine how subsea production equipment and other advanced technology being developed by industry could be integrated into a subsea production system, suitable for long distance subsea tiebacks. Long distance tieback advancement for a vast range of field developments and through the use of advanced technologies, to achieve (1) Lower capital costs; (2) increased production and ultimate recovery; and, (3) improved operational flexibility and efficiencies.
Life extension / continued service for floaters is a major industry issue, with many deep water facilities approaching the end of their original design lives. While work has been completed on integrity management (IM) focused on structural issues, no guidance has been developed in IM of marine systems such as controls, ballast, safety, etc. this work will provide this missing guidance.
A quest for step-change cost reduction solution via an innovative floating concept. This project will evaluate technical merits and cost comparisons of a simpler FPSO hull concept that offers multiple development options at lower costs.
Improve reliability of mooring systems and prevent multi-line failures through improved Standards. Develop codes and standards to close critical gaps.
Evaluate fitness of existing risers and capability of current in-situ inspection methods; develop a process to safely maximize the use of existing riser systems.
