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.

AbstractObjectives: In recent years there have been a number of high profile cases in Irish psychiatry where consultant psychiatrists have been subjected to serious physical assaults. The last survey of assaults on consultant psychiatrists in Ireland was carried out in 1998. Therefore we sought to update the data on this topic.Method: An anonymous questionnaire was sent out by post to all consultant psychiatrists (n = 330) identified as currently working in the Republic of Ireland.Results: The response rate was 48.2%. Sixty per cent of respondents were working in general adult psychiatry and respondents were evenly spread throughout the country. Ninety per cent of respondents had been the victim of verbal aggression/intimidation/threatening behaviour while 55% had been physically assaulted. The majority of incidents involved male patients aged between 21-40 years with a diagnosis of paranoid schizophrenia. Nearly 66% of incidents of physical violence occurred during a relapse of illness. The perpetrator had a history of violence in approximately half of all reported incidents. Physical assaults tended to occur more commonly in inpatient settings (63.7%).Incident reporting occurred more often in physical assaults with 66% reported informally to colleagues and 20% reported to An Garda Siochana (police force of Ireland). Eighty-nine (56%) consultants described feeling ‘safe’ at work. Less than 50% reported the provision of standard safety equipment in the workplace and nearly half ofrespondents had not attended any safety training courses since their appointment. Longer experience working as a consultant psychiatrist did not appear to have an impact on reducing the rate of assaults. In addition, those who attended safety training courses did not report a reduced rate of physical assaults.Conclusions: These findings highlight the need for both organisational and personal changes in practice in order to reduce the assault rate. Organisational changes include the provision of appropriate safety equipment, safety training for consultants, enhancing multidisciplinary teams and utilising risk assessment. Consultants' personal practices to improve their safety may offer useful information for inclusion in safety training courses. This is an area which merits further research.

ObjectivesTo investigate the risk reduction and benefit of wearing body protection/safety vests in equestrian sports.MethodsA comparison of equestrians wearing body protective vests and those not wearing vests was performed using incident report data of 718 participants in the United States Pony Clubs during 2011–2017. Data obtained included age, gender, certification level of member, type of activity, description of incident, description of injuries, what protective equipment was worn and other possible contributing factors.ResultsWhile wearing body protective vests when riding on the flat or for show jumping was not correlated with a decrease in injuries, wearing vests for cross country was correlated with decrease in reported injuries (p=0.036) and showed a trend towards a lower incident severity level (p=0.062). Wearing body protection during cross country reduced the relative risk of injury by 56%. While the volume of incidents varied with a rider’s experience level, the number of serious injuries did not appear to correlate with lesser equestrian experience.ConclusionsWhile equestrian sports are considered to have a certain degree of risk associated with them, there are ways to make them safer. Wearing safety equipment, such as helmets and body protection, and obtaining education and experience can lessen the chance of incurring serious injuries.
