The offshore industry's experience in the past 20-30 years indicates that due to frequent traffic of supply ships around the offshore platforms the probability of occurrence of collision with such vessels is relatively high. The influence of various scenarios of supply ship collisions is investigated. In a previous study on ship impact on an 8-leg North-Sea Jacket Platform by Amdahl et al and also other studies the effect of jacket pile-soil interaction was not considered. Several supply ship collision analyses are carried out for bow stern and broadside impact scenarios on an 8-leg North-sea Jacket platform. It is observed that by taking into account the jacket-pile-soil interaction effects in particular in softer clay soils the amplitude of displacement response after supply ship impact at the deck level is increased due to yield in the upper soil layers. Contrary to this finding less linear dynamic effects can be seen in the studied jacket-pile-soil system subjected to the supply ship impact. It can also be concluded that for a soft impact scenario the dynamic effects in the global response of the platform located in the mainly OC clayey soil may be much less than those for hard impact scenario on the same platform. For instance for a brace impact at its mid-span a less significant dynamic effect has been observed than for a leg impact. The duration of impact in such cases is shown to play an important role in determining the dynamic influence of the platform response. The relative energy absorption of the platform is shown to be more for broadside loadX23134 The influence of diffraction on the stability assessment of ships

Findings of an experimental project into minimum crewing on the Transatlantic Group of Sweden's G3-class roro containership Companion Express during regular service European and Atlantic liner trades are reported - the ship was routinely operated by a small "core" crew with extra hands on as necessary - costs crew training and alterations to ship equipment and outfitting are discussed.

Results of a study on the effectiveness of a DP training scheme developed by the Nautical Institute are presented. The assessment was based on an analysis of the NI course assessment forms a mailed questionnaire sent to past students and personal observations of student reactions to simulated DP incidents from the Department of the Environment's report.

Large motor drives are being increasingly used on offshore platforms and ships. This paper describes some of the harmonic problems experienced to date on offshore platforms including the effect of commutation spikes. Methods of calculation are discussed along with the possible excitation of electrical resonances or mechanical torsional resonances.

A cylinder pressure measuring system based on external strain gauges linked to the cover studs (rather than vulnerable internal sensors) is exploited by MAN B&W for the new on-line version of its Computer Aided Performance Analysis system. The article provides particulars of the system in some detail covering such matters as the need for a reliable but cheap cylinder pressure sensor.

A paper focusing on ship casualty statistics in Korea from 1988 to 1922. Statistics from both domestic and worldwide publications are examined and discussed with particular emphasis on the importance of factors such as social mores and cultural environs. It is suggested that different safety yardsticks should be used for evaluating ship casualties for different countries.

When Shell's Shearwater field comes on stream it will form a key piece of infrastructure in unlocking gas and condensate reserves in the high pressure high temperature areas of the North Sea. The development is based on a wellhead platform (WP) bridge-linked to a Process Utilities Quarters (PUQ) platform. First gas export is scheduled for June 1999.

Findings from audits on DP vessels are presented. The most suitable body to take on the responsibility of an exhaustive baseline DP audit of diving vessels is the classification society. Until such a system is introduced field operators will continue to apply their own standards in pursuance of their overall obligations.
