Water Collection Purification System: Identifying CF Capabilities and Requirements, and Assessing off-the-Shelf Purification Systems
2006Co-Authors: Bernadette QuemeraisAbstract:Abstract : The Water Collection Purification System project is part of the Shelter and Survival Equipment project (12cy) sponsored by DLR. The objective is to provide to the military a water purification system suitable for all operational/environmental conditions. The capabilities of the CF in terms of both purification and testing have been assessed. Users of the current system as well as PMed technicians have been contacted in order to discuss both the capabilities and the requirements. An assessment based on manufacturer specifications of the off-the-shelf purification systems has been done. The identification of commercial system capabilities and their validation will be done during the next two years.

An investigation into existing Survival Equipment / systems and the possibility of applying current technology to a new design.
2003Co-Authors: Gareth James HollowayAbstract:The project was undertaken as it was considered that, with an ever increasing number of people taking to the water in yachts, current Survival Equipment was not up to the task of offering maximum safety to the crews and vessels when compared to related technological advances in other industries. To assess if there is a need for a new product, the project investigates a number of key areas. Initially the history of accidents at sea, specifically looking into the 1979 Fastnet and 1998 Sydney-Hobart races, previous accounts from sailors who have lost vessels and been stranded at sea and accident statistics. It then investigates what is currently on offer in the way of Survival Equipment in the marine industry and considers these against safety Equipment in comparable industries. After concluding that current systems, especially liferafts, have a large number of publicised shortcomings, a new design/ concept was conceived. The design utilises current liferaft technology and using a design employed in the aeronautical industry as its basis, incorporates an inflatable collar into the hull of the vessel. This design addresses all of the identified drawbacks and provides great improvements to vessel stability, crew safety and recovery. To test the design all the data was entered into stability calculations. The results from this proved better than expected. A 1/8th scale model was created using a Whitbread 60 hull. This model was subjected to an inclining experiment, the results of which were compared to the theoretical results for the same model to test the accuracy of the calculations. The results from both methods were very close. This proved that the theoretical method can be used to accurately predict increases in stability. In both cases the experiment was deemed a complete success. The latter section of the report suggests ways in which the design can be incorporated into the hull to offer maximum results, whilst requiring as little effort from the crew as possible. It then investigates how to further develop the project and lists potential issues associated with a development program. These are overcome by the recommendation of introducing the design to a company who already has experience at producing marine safety systems. It also gives recommendations to the marine industry as to how best to improve the regulations for marine safety Equipment so that a universal standard can be rapidly adopted.

u s army aviation life support Equipment retrieval program u s army aircrew rescue and factors delaying rescue
1996Co-Authors: James E BruckartAbstract:Abstract : Despite strict flight discipline, U.S. Army aircraft infrequently suffer inflight mishaps. This is a retrospective study of aircrew Survival and rescue in 97 mishaps investigated by the U.S. Army Safety Center from October 1988 to June 1990. To identify factors delaying rescue, later mishaps were compared with 37 mishaps where the time to reach the mishap site exceeded 2 hours. The average time to reach a mishap site was 2.2 hours, but over 90 percent were reached within 2 hours. There were two or more survivors at 82 percent of the sites, and 98 percent of the downed aircrew had at least personal Survival Equipment available. Adverse operational and environmental factors were more common in delayed rescue mishaps. Sudden aircraft failure was three times more common in prolonged rescue mishaps, while night or instrument meterologic conditions contributed eight times and four times greater risk of delay, respectively. Rescues in mountainous terrain or over water were seven times more likely to be delayed. While fatalities were more common with prolonged rescue, there were no mishaps where a delay in reaching the crash site resulted in loss of life.

New Cold Water Survival Equipment
Offshore Technology Conference, 2013Co-Authors: Ralph BuxtonAbstract:A computer simulation of a hypothetical Great Lakes winter-season ship sinking casualty indicates that current Survival systems wil save 28 percent of the crew. In order to raise the percentage saved, improvements are needed, not only for group Survival craft such as lifeboats and liferafts, but also individual Survival Equipment. An individual Survival system was developed that provides man-overboard protection and a ship-abandonment mode for individuals. The system consists of a work jacket and a ship escape system. The work jacket has been tested with human subjects in 30 degree F water, 20 degree F air, and 20-mph winds. Tests were terminated after 42 minutes because of subject's discomfort. The ship escape system was tested under similar conditions, and the test was terminated after 4 hours, although Survival time can be extrapolated to 8 to 10 hours.

Sigurnost na tankerima za prijevoz kemikalija s posebnim osvrtom na zaštitu zdravlja posade i zaštitu od požara
University of Dubrovnik. Department of Maritime Transport., 2019Co-Authors: Milić PauloAbstract:Prijevoz tekućeg tereta morem postoji još od trećeg stoljeća prije nove ere, kada su se tekućine prevozile u amforama. U današnje vrijeme se tekući tereti prevozi posebno građenim brodovima odnosno tankerima. Tanker je brod za prijevoz tekućih tereta kojemu je čitav prostor za teret podijeljen uzdužnim i poprečnim pregradama na nepropusna odjeljenja, koja se nazivaju tankovima. Približno se 30% sveukupne trgovine odnosi na kemikalije i produkte. Kemijski tankeri prevoze tekuće terete izuzevši sirovu naftu i terete koji zahtijevaju značajnije hlađenje ili tlačenje. Tankeri koji su namijenjeni prijevozu kemikalija vrlo su specifični brodovi zbog kompleksnosti građe i svojstva samih tereta. Tako se vrlo često u njima prevoze eksplozivni, toksični i nagrizajući (korozivni) tereti. Upravo zbog toga mnogo se pažnje obraća na tankove tereta i njihovu sposobnost da sačuvaju integritet i čistoću tereta. Gotovo uvijek je riječ o opasnim teretima, pa je održavanje protupožarnih sustava, sustava za sprečavanje onečišćenja mora i opreme za spašavanje u slučaju havarije očekivano na visokom nivou. Najviše standarde mora zadovolji sigurnosna oprema za posadu koja uključuje veliki broj predmeta i aparata. specijalna odjeća i obuća, aparati za disanje, razni ispitivači kvalitete zraka i atmosfere u tankovima tereta. Protupožarna zaštita, osim odgovarajuće opreme i sredstava za gašenje podrazumijeva i obučavanje ljudi, kako bi bili u stanju adekvatno i efikasno koristiti sredstva koja im stoje na raspolaganju. Najjača obrana od požara je poduzimanje svih potrebnih sigurnosnih mjera da se on uopće ni ne dogodi. Održavanje i testiranje uređaja za prevenciju i zaštitu vrši se onda kada nema opasnosti, kada za to ima dovoljno vremena.Transportation of sea freight with sea has existed since the third century BC, when liquids were transported in amphorae. Nowadays, current cargoes are carried by specially built ships or tankers. Tanker is a freight cargo vessel whose entire cargo space is divided by longitudinal and transverse bulkheads into the sealed units, called tanks. Approximately 30% of the total trade relates to chemicals and products. Chemical tankers carry liquid cargoes, excluding crude oil and cargoes that require significant cooling or compression. Tankers destined to transport chemicals are highly specific ships due to the complexity of the material and the properties of the cargo itself. Thus, they often carry explosive, toxic and corrosive cargo in them. That is why much attention is paid to the cargo tanks and their ability to preserve the integrity and cleanliness of the cargo. Almost always there are dangerous cargoes, so the maintenance of fire-fighting systems, marine pollution prevention and Survival Equipment is expected to be high-level. The highest standards must meet the safety Equipment of the crew including a large number of items and appliances. special clothing and footwear, breathing apparatus, various air quality testers and atmospheres in cargo tanks. Fire protection, with the exception of adequate Equipment and extinguishing agents, also involves training people to be able to adequately and efficiently use the resources available to them. The fiercest fire defense is taking all the necessary security measures to prevent it from happening at all. Maintenance and testing of the prevention and protection device is performed when there is no danger when there is enough time for it
