There has been an increase in oil spill research and development, especially after the Deepwater Horizon accident in the Gulf of Mexico. However, the public resources seem to be concentrated in the life sciences, rather than in engineering. The effect of oil on seaweeds and the effect of spilled oil on seabirds, for instance, seem to take precedence in government research funding, rather than engineering issues. If engineering preventive procedures and equipment are in place, then these adverse effects can be viewed as secondary. Offshore oil and gas production is an engineering endeavor, and it makes sense to expand resources in key aspects of engineering to allow for safer practices with regard to this endeavor. Offshore oil production is principally done by public companies, so it is logical that the government requires certain safety and operational standards with regard to permitting related offshore activities. It should follow that high governmental safety rules be set, and that production companies be aided by science and technology research that has been completed. A second thrust is to fund research and development for up-to-date science and engineering to meet the challenges of deep water drilling, especially in the area of machinery and devices that would help in mitigating accidents in deep water.

Offshore oil and gas production is now reaching to great depths, in excess of 1000 m, in the Gulf of Mexico and the Campos Basin, offshore Brazil. It will not be long before Australian companies look towards probable reserves in deeper waters that still remain within the Australian exclusive economic zone. Production concepts for deep and ultra deep water thus need to be studied and researched, and a constant watch should be maintained on developments around the world in this area.This paper presents two popular, and constantly evolving, concepts for deep water, namely: tension leg platforms (TLP) and spars. Tension leg platforms have been in existence for about 14 years, and are actively sought for deep water by worldwide operating companies. They are vertically moored by means of taut tethers which present interesting motion characteristics and unique hydrodynamic problems. Spar platforms are currently being installed for production purposes. These are large deep draft cylindrical structures moored by catenary or taut spread mooring systems. Physical details, advantages and limitations of both systems are discussed.While many aspects of these production systems are now understood, there are still several unknowns. Deeper waters translate to newer problems. Potential problems of the future are discussed in this paper, and research needs are highlighted.

Production units located in the Brazilian marine environment are responsible for the production of 95.7% of oil and 78.8% of natural gas of Brazil causing economic, environmental, and social impacts motivating us to construct a system of indicators as a tool aimed to improve the sustainable management practice of these production units. To date, one of the tools most used by the oil industry is the sustainability report, oriented by guidelines from international organizations. However, these reports have a corporate character being unable to help the sustainability management of production units’ activities. The indicators were selected based on a systemic approach, using current knowledge on sustainability indicators, together with the survey of aspects relevant to the operation and management of offshore oil and gas production units. This paper describes the proposed indicators and presents the hierarchical structure of the system, built on the economic, environmental, social, and operational dimensions. The application of the proposed system of indicators, based on multicriterial and multiple decision-making analyses, validates a complex decision process, providing improved sustainable management of offshore production units by identifying points for which the necessary measures and actions can be implemented. Keywords: offshore oil and gas production; sustainability indicators; multicriteria and multiple decision-making analyses.
