ABSTRACT Oil production in the North Sea and some other potentially important areas is much more difficult than offshore drilling was in the past. It is assumed that the difficulties are properly compensated so that blowout probability is not increased. The very much higher productivity of the wells, the expected longer duration of a blowout and the greater difficulties of surface containment obviously increase the probable oil spill volume. Exactly how much it is increased statistically is not known. A factor of 100 is suggested. For this reason, such areas need a much better oil spill defense than used in the past in other areas. The author is engaged in a feasibility study on underwater collection for control of underwater blowouts. The proposed equipment consists of a heavy submersible rig which can place a collection bell over the blowout orifice: the petroleum is then ducted from the bell to a surface vessel where the gas is burned and the oil collected or burned.

A version of this paper was first presented at the Royal Institute of Navigation NAV 08 Conference held at Church House, Westminster, London in October 2008.The North Sea oil platforms are reliant on regular and reliable helicopter operations for the movement of staff and supplies. The environment is challenging and there have been six fatal accidents incurring the loss of 79 lives since the mid-1970s. The need for accurate and reliable helicopter approach procedures has been identified and this paper reports the results of a feasibility study into the use of EGNOS-based approaches to oil platforms in the North Sea.
