Second International Conference on Composite Materials for Offshore Operations

This conference will provide a form for researchers and engineers from petroleum companies, platform operators, engineering service industry, material suppliers, manufacturers, regulatory and certification agencies, and academic institutions to:

1. report and review major worldwide, state-of- the-art
developments on composites offshore;

2. identify and forecast new opportunities of utilizing
composites in the petroleum industry to save cost
and provide enabling capabilities;

Underwater Welding Development Program, Phase II

This is a Joint Industry Project (JIP). The purpose is to develop welding electrodes to make wet welds that will, to the greatest extent possible, meet the requirements for Class A dry welds. This will be done be compensating for pressure-induced changes in weld metal. A realistic goal may be Class A welds to 100 feet, Class B+ (reduced porosity and increased ductility) from 100 feet to 200 feet, and consistent Class B welds to 300 feet.

International Workshop on Advanced Material for Marine Structures

This is a Joint Industry Project (JIP). The purpose of this project is to set up a workshop to define the state of utilization of advances materials in marine structures. The workshop will identify the technical and nontechnical barriers which hinder a fuller utilization of advanced materials. Structural design specialist, welding engineers, inspectors, and corrosion experts with special knowledge of materials properties will provide a breadth of knowledge and experience to the endeavor. The workshop will produce an archival record currently planned to be a hardbound book.

Support for the Composites Engineering and Applications Center (CEAC) for Petroleum Exploration and Production

This is a Joint Industry Project (JIP) to support the creation and maintenance of the CEAC at the University of Houston. The specific goals proposed for the center were to:

(1)identify and quantify the opportunities for utilizing composite materials in the petroleum industry;

(2) develop composites applications that will reduce the cost of petroleum operations;

(3) establish the technical infrastructure needed by the petroleum industry to use composite products;

Fatigue Strength of Grouted Connections

This is a Joint Industry Project (JIP). To establish design recommendations using available test information on grouted connections. The calculation of safety factors for static strength of grouted connections is necessary to design safety standards which are uniform and like that of other structural components. It is necessary to establish that the provisions for other failure modes will still be adequate. The aim is to provide a sufficient measure of safety against fatigue failure of grouted connections.

International Workshop on Composite Materials for Offshore Operations

The objective was to conduct an international workshop on the use of composite materials in offshore operations. The initial costs of composites are comparable to ordinary steel. Composites offer cost savings over specialized, i.e. corrosion-resistant metals. The performance benefits of composites include increased reliability because of corrosion resistance and structural superiority through weight savings, higher stiffness and ability to better tailor the structure to the load.

Fatigue of High Strength Steels for Innovative Offshore Structures

The objective was to assess and characterize the fatigue properties of several new high strength structural steels under consideration for innovative offshore structures in conditions which are applicable to their use. The project was a Joint Industry Project (JIP) with six industry participants and support from the American Petroleum Institute (API).
