Ocean Observing

Abstract The Gulf of Mexico is one of the most important ecologic and economic resources in the United States. To help protect this resource and to support a wide range of decision-making, the Gulf of Mexico Ocean Observing System (GCOOS) is being built to be a sustained network that provides integrated coastal and ocean data from a diverse array of data sources in real time, near real time, and historically. GCOOS is 1 of the 11 regional components of the U.S. Integrated Ocean Observing System (U.S. IOOS). Because of the very limited resources available to date, the GCOOS Regional Association (GCOOS-RA), which is working to build the GCOOS, has not deployed any of its own observing systems. That, coupled with strong volunteer participation, has led the GCOOS-RA to focus its efforts on integrating existing federal and non-federal (regional, state, local, academic, and private) assets and data. The GCOOS-RA is working to adapt and expand the GCOOS to address data gaps identified by stakeholders and to apply the lessons learned from events such as the Deepwater Horizon (DWH) oil spill, harmful algal blooms (HABs), Gulf hurricanes, and hypoxia. The contributions of GCOOS demonstrate the value of a sustained U.S. IOOS and provide specific lessons necessary for the successful build-out of the system in the Gulf of Mexico. However, the lessons also demonstrate the importance of applying additional resources to improve GCOOS’ ability to meet stakeholder needs such as in response to environmental events. A full, comprehensive GCOOS, exclusive of federal assets, is estimated to cost roughly $22 M for capital and $20-25 M/year for operation and maintenance (O&M) in the near term with approximately an additional $25 M in capital to complete the build-out and $35-50 M/year in O&M costs to maintain the system—an excellent value when compared to the billions of dollars of economic impact of four major industries in the Gulf of Mexico: oil and gas, tourism and recreation, fishing, and shipping.

Reef Fish Species

Specifying annual catch limits for artisanal fisheries, low economic value stocks, or bycatch species is problematic due to data limitations. Many empirical management procedures (MPs) have been developed that provide catch advice based on achieving a stable catch or a historical target (i.e., instead of maximum sustainable yield). However, a thorough comparison of derived yield streams between empirical MPs and stock assessment models has not been explored. We first evaluate trade-offs in conservation and yield metrics for data-limited approaches through management strategy evaluation (MSE) of seven data-rich reef fish species in the Gulf of Mexico. We then apply data-limited approaches for each species and compare how catch advice differs from current age-based assessment models. MSEs identified empirical MPs (e.g., using relative abundance) as a compromise between data requirements and the ability to consistently achieve management objectives (e.g., prevent overfishing). Catch advice differed greatly among data-limited approaches and current assessments, likely due to data inputs and assumptions. Adaptive MPs become clearly viable options that can achieve management objectives while incorporating auxiliary data beyond catch-only approaches.

Abstract The eye of Hurricane Katrina passed within 49 n mi of an oceanographic observing system buoy in the Mississippi Bight that is part of the Central Gulf of Mexico Ocean Observing System. Although a mechanical anemometer failed on the buoy during the hurricane, a two-axis sonic anemometer survived and provided a complete record of the hurricane’s passage. This is the first reported case of a sonic anemometer surviving a hurricane and reporting validated data, and it demonstrates that this type of anemometer is a viable alternative to the mechanical anemometers traditionally used in marine applications. The buoy pitch and roll record during the storm show the importance of compensating the anemometer records for winds oblique to the horizontal plane of the anemometers. This is made apparent in the comparison between the two wind records from the anemometers during the hurricane.

Abstract Given the increased demands on the production of hydrocarbons and cost-effectiveness for the Operator's development wells, the industry is challenged to continually explore new technology and methodology to improve drilling performance and operational efficiency. In this paper, two recent case histories showcase the technology, drilling engineering, and real-time optimization that resulted in record drilling times. The wells are located on shallow water in the Gulf of Mexico, with numerous drilling challenges, which typically resulted in significant Non-Productive Time (NPT). Through close collaboration with the Operator, early planning with a clear understanding of offset wells challenges, well plan that minimize drilling in the Upper Cretaceous "Brecha" Formation were formulated. The well plan was also designed to reduce the risk of stuck pipe while meeting the requirements to penetrate the geological targets laterally to increase the area of contact in the reservoir section. This project encapsulates the successful application of the latest Push-the-Bit Rotary Steerable System (RSS) with borehole enlargement technology through a proven drilling engineering process to optimize the drilling bottomhole assembly, bit selection, drilling parameters, and real-time monitoring & optimization The records drilling times in the two case histories can be replicated and further improved. A list of lessons learned and recommendations for the future wells are discussed. These include the well trajectory planning, directional drilling BHA optimization, directional control plan, drilling parameters to optimize hole cleaning, and downhole shocks & vibrations management during drilling and underreaming operation to increase the drilling performance ultimately. Also, it includes a proposed drilling blueprint to continually push the limit of incremental drilling performance through the use of RSS with hydraulics drilling reamers through the Jurassic-age formations in shallow waters, Gulf of Mexico.

In this chapter, we discuss how a leading telecommunications software development company went about outsourcing some phases of the system development life cycle (SDLC) of network management systems in order to achieve both the short-term tactical goals as well as the long-term strategic goals. We present a framework consisting of seven factors that should be used by companies using outsourcing as a business strategy. This framework was used to analyze the outsourcing practices used by this company. The framework includes the driving forces for offshore outsourcing, the selection process of outsourcing vendors and the infrastructure (communication links, hardware, software, and organizational structure) that was needed to insure that the outsourced work meets company’s internal quality requirements, which are derived from CMM5 and ISO9001 certifications. We also present the challenges of making these things happen, what worked well, and the lessons learned.

Multiple Experts

Knowledge acquisition is a major task in expert system development. This paper proposes one way of acquiring knowledge for expert system development: through the use of the Internet. Internet resources (e.g. Usenet groups, ListServ discussion lists, archive sites and on-line literature/database searches) are knowledge sources. Internet tools such as newsreaders, electronic mail, Telnet, FTP, gophers, archie, WAIS and World Wide Web provide access to these sources. The results of an exploratory study that examined the use of the Internet as a knowledge source are presented here in conjunction with a framework for using the Internet in the planning phase. Four major advantages can be found in this: the availability of multiple experts in multiple domains, the interaction of domain experts and end users, time/cost savings, and convenience. The lessons learned and some additional issues are also presented.

The Individual

The research and development of a unique combustion engine is presented. The engine converts the thrust from ramjet modules located on the rim of a disk into shaft torque, which in turn can be used for electrical power generation or mechanical drive applications. A test program was undertaken that included evaluation of the pre-prototype engine and incorporation of improvements to the thrust modules and supporting systems. Fuel mixing studies with vortex generators and bluff-body flame holders demonstrated the importance of increasing the shear-layer area and spreading angle to augment flame volume. Evaluation of flame-holding configurations (with variable fuel injection methods) concluded that the heat release zone, and therefore combustion efficiency, could be manipulated by judicious selection of bluff-body geometry, and is less influenced by fuel injection distribution. Finally, successful operation of novel fuel and cooling air delivery systems have resolved issues of gas (fuel and air) delivery to the individual rotor segments. The lessons learned from the pre-prototype engine are currently being applied to the development of a 2.8MW engine.

In Mexico, the Federal Commission of Electricity (CFE) is the public entity that is responsible for the annual preparation of the national programme of the electricity system development with a 15 year horizon (POISE in Spanish). Besides this national planning process, there are regional plans as well as others regarding the development of hydroelectric and geothermoelectric projects; these plans are essential inputs to prepare the POISE. Another key decision window is the site selection of the projects listed in the Program. For a few years the Environmental Protection Division of CFE has been promoting the incorporation of SEA into the decision-making processes of the company. Two regional SEAs have been made so far. This paper presents the actions carried out to incorporate SEA into CFE since 2002, as well as the methodologies followed in each of the two cases, and primarily the lessons learned from these experiences.
