More than a decade ago, oil drillers and naval architects started to use vessels instead of fixed structures for offshore drilling. A multitude of novel platform concepts were developed which allowed the tremendous spreading of offshore oil activities. Today, search for oil spreads into areas of greater depth and farther away from the shores. This requires new developments of technology over a broad spectrum. The latest concepts of underwater oil production systems are briefly described.

Significance Rising output from the Gulf of Mexico, which accounts for about 16% of total US production, will help offset some of the falling output from onshore shale projects, although overall production is still declining following the collapse in prices. Impacts The downturn in new offshore oil and gas activity will hit the state budgets of Alabama, Louisiana and Texas. Offshore drilling services specialists will see revenues fall, as companies cut back drilling and push for reduced rates. In the event of a sustained price recovery, US production will primarily be driven by renewed shale drilling, not offshore.

As onshore oil and gas deposits are becoming more difficult to locate, and as the world demands for energy continue to increase at an alarming rate, oil companies are channeling much of their exploration activities towards offshore operations, and in particular, towards operations centered off Canada's coast lines. Because of the environment, offshore drilling presents problems which are novel to the onshore-geared oil industry. J. M. Killey discusses in detail many of the considerations involved in drafting the offshore drilling contract, concentrating on problems such as the liability of the various parties; costs; scheduling; pollution; conflict of laws; etc. Similarly, he discusses service contracts (such as supply boat charters; towing services; helicopter services; etc.^ which are necessity to the operation of an offshore drilling rig. To complement his paper, the author has included number of appendices which list the various considerations lawyer must keep in mind when drafting contracts for offshore operations.

Offshore production terminals and deepwater risers are seeing increasing use by the offshore oil industry. The structural design of these units presents a unique challenge compared to other offshore systems. Development of design loading conditions and fatigue histories is especially interesting due to the complex interaction of nonlinear riser and vessel dynamics, the statistical nature of maximum loads and the need to consider directionality as well as the magnitude of environmental loading. This paper presents a complete procedure for predicting design loads and fatigue histories for production risers and offshore terminals. The emphasis will be on systems wherein a dedicated vessel is connected to the riser by a rigid mooring arm. A number of structural design configurations will be surveyed. Techniques for preliminary sizing, dynamic analysis, model testing and fatigue analysis will be discussed. The application of this procedure to several specific design cases will be summarized.
