The COVID-19 pandemic forced surprised governments worldwide to act fast and decisively, often revealing lack of preparation for this kind of situation. However, such crises are expected to occur far more frequently than ever before. To keep societies prospering, governments, administrations, and civil servants will have to adapt quickly and effectively—and hence need to develop the required capabilities (e.g., appropriate policies, strategies, knowledge, skills). To deepen our understanding of appropriate action in face of crises, resulting consequences for stability and required, demanded or enforced behavior of people, we propose the concept of resilience. Resilience, we argue by way of five propositions, helps articulating the underlying dynamics in society and its administrative systems in order to allow for a sustainable incorporation of the long-term perspective in the short-term strategy, particularly in times of disturbances and temporary perturbations.

The origins of offshore drilling work and the development of structures used at sea are traced. Comparison of the various types illustrates the advantages and disadvantages of each. Tables show the numbers in operation, being built, and the apparent liability of each type to damage. Typical bore-hole structures are illustrated, the need for undersea well-heads explained and their development into a sea-bed completion is discussed. Much more research is necessary before this can be considered a practical proposition. The design of drilling barge equipment is compared with typical land rigs and the development of drilling equipment, including the sophisticated electric drive and turbo-drill, discussed. Rigs in various types of barge are compared. Fire precautions and other safety equipment are described. The problems associated with control by the driller lead to complications of motive power layout. The lecture describes in some detail the design of the semi-submersible drilling barge Sea Quest, illustrates the weight problems and their effect on floating stability and indicates the need for management decisions on the degree of resistance to damage. This is measured by the variable deck load of drilling equipment that can be held on board and the degree of weather deterioration that can be tolerated before disengaging the drill from the hole. The need for, and extent of, diving is discussed, with some comparison between diving vehicles. Weather too is an essential factor of work in the North Sea and both pre-surveys and day-to-day reporting are described.

This paper (SPE 52993) was revised for publication from paper SPE 36536, first presented at the 1996 SPE Annual Technical Conference and Exhibition, Denver, 6-9 October. Original manuscript received for review 11 October 1996. Revised manuscript received 22 September 1998. Paper peer approved 23 September 1998. Summary A Wireline retrievable coring system for use with conventional drilling equipment is described. The coring system was developed and tested for application in evaluating coalbed methane prospects where a large quantity of core is required, and it is essential that the core is processed soon after it is cut. A drill plug allows for alternation between coring and drilling without tripping the drillstring. The system is particularly advantageous for coring long intervals, multiple zones relatively close together, or when the exact target depth is unknown. The system has been used to core more than 4940 m (15,057 ft) in Poland, Germany, and France, with a combined core recovery of 94%. In addition, the impact of varying rig costs on total savings is factored into the overall economic evaluation of the system. P. 489

Experience shows that one of the most time consuming aspects of interactive application program design is the development of the human interface. This paper describes a set of procedures for aiding the development of well-engineered interactive programs in a teaching environment.
