seasickness in totally enclosed motor propelled Survival Craft remedial measures
Aviation Space and Environmental Medicine, 1992Co-Authors: J P Landolt, C MonacoAbstract:Totally-enclosed motor-propelled Survival Craft (TEMPSC) are used to evacuate the crews of mobile offshore drilling units in emergencies. The small size and flat bottom of the TEMPSC predispose most occupants to seasickness, even in relatively calm waters. This paper discusses efforts required to improve the well-being of occupants in terms of reducing seasickness, dehydration, hypothermia, anxiety, and the other factors that contribute to loss of comfort and the will to survive. Specific recommendations include the provision of climatic control to regulate temperature, remove odors and provide fresh air; potable water, electrolytes, and Survival rations; and an ample supply of motion sickness bags. Overcrowding should be avoided. Anti-motion-sickness drug therapy to control vomiting should be administered in two ways: initial injection of intramuscular scopolamine for fast action followed by a transdermal ear patch for long-term protection. Leadership and seasickness management should be requisite Survival training for all oil rig workers. Language: en

seasickness in totally enclosed motor propelled Survival Craft five offshore oil rig disasters
Aviation Space and Environmental Medicine, 1992Co-Authors: J P Landolt, I M Light, M G Greenen, C MonacoAbstract:Five mobile offshore drilling unit disasters--Alexander L. Kielland, Ocean Ranger, Vinland, Ocean Odyssey, and Rowan Gorilla I--were studied to assess the degree to which seasickness occurs and endangers the lives of occupants of totally-enclosed motor-propelled Survival Craft (TEMPSC). Thousands of other peacetime marine incidents were reviewed and a literature search was conducted to assess the same seasickness problem. The one reported death in the Vinland abandonment appears to be the only one that could be associated, even remotely, with seasickness. It cannot be established whether or not seasickness contributed to the cause of death in the case of the Ocean Ranger victims, but it did occur in 75% or more of TEMPSC occupants in the other four rig disasters. It has occurred both in relatively calm waters of 1-m wave height and in severe seas of 15-m heights. Evacuees in an intact TEMPSC are able to survive many hours of severe seas; consequently, they should not be rescued until the weather and sea conditions improve. Moreover, practical Survival training and good leadership is a principal cornerstone in the amelioration of seasickness. Language: en

Occupant Habitability within a Totally Enclosed Motor Propelled Survival
2020Co-Authors: A Baker, Antonio Simoes Re, Jonathan Power, Scott MackinnonAbstract:While a totally enclosed motor propelled Survival Craft (TEMPSC) can provide a temporary safe haven during an emergency situation, the comfort and habitability of its occupants may be called into question. Exposure to carbon dioxide (CO₂), carbon monoxide (CO), increasing ambient temperature and humidity, and poor light and noisy environments may not only jeopardize the health and safety of TEMPSC occupants, but negatively affect the outcomes of the evacuation, escape and rescue (EER) events. Experimental trials were performed over a 3-year period during various climatic conditions consistent with expected abandonment situations. An IMO-SOLAS TEMPSC rated for 20-occupants, but retrofitted as a research Craft, was instrumented to collect relevant interior cabin information. Trials conducted in pack ice were done with sufficient speed to facilitate the passive ventilation system within the TEMPSC, while those conducted on dry land in a stationary position showed CO₂ levels that rose well above safe values. Rising CO₂ levels within the TEMPSC may create a dangerous environment for the occupants. Thus, it is necessary to investigate the implementation of an active ventilation system within the TEMPSC that would mitigate the risk of increasing levels of CO₂ gas within the vessel.

carbon dioxide accumulation within a totally enclosed motor propelled Survival Craft
Ergoship 2011, 2011Co-Authors: A Baker, A Kavanagh, V Thistle, Scott Mackinnon, Simoes A Re, Jonathan PowerAbstract:Exposure to high levels of carbon dioxide (CO2) may have adverse effects on human health and performance, and the likelihood of such an event may be increased when situated in a confined space like a fully loaded totally enclosed motor propelled Survival Craft (TEMPSC). The goal of this research was to quantify the occupant complement to CO2 concentration relationship in order to provide guidance regarding TEMPSC ventilation strategies. A pool of 15 subjects was loaded systematically into a IMO-SOLAS TEMPSC in group sizes ranging from 1 to 15 persons. Repeated measures were taken, and in special cases subjects donned SOLAS-approved Survival suits. Results showed that increasing the number of occupants greatly increased the amount and rate of CO2 accumulation, thereby increasing the frequency at which the TEMPSC must be ventilated to mitigate the risk of CO2 exposure.

A preliminary ergonomic assessment of piloting a lifeboat in ice
Safety Science, 2011Co-Authors: Michael J. Taber, Antonio Simoes Re, Jonathan PowerAbstract:This paper examines human factors associated with piloting a totally enclosed motor propelled Survival Craft (TEMPSC or lifeboat) in ice. The first section of the paper describes the use of a usability assessment scale to evaluate the coxswain's (TEMPSC captain) control panel. The second portion examines environmental conditions (habitability) inside the lifeboat during evacuation. All testing was completed in conditions that were consistent with those that might be experienced by ship or offshore oil and gas crewmembers in the event of abandonment due to an onboard emergency. Results indicated that the lifeboat test configuration presented considerable challenges to usability/functionality as well as habitability. These findings suggest that further research should be conducted to evaluate the safety of all existing lifeboat designs. Finally, it is recommended that the international maritime organization (IMO) and safety of life at sea (SOLAS) Convention should mandate user-centered design evaluations for future lifeboat manufacturing.

Preventing deaths in Alaska's commercial fishing industry.
International journal of circumpolar health, 1998Co-Authors: G A Conway, J M Lincoln, S A Jorgensen, M L Klatt, J C ManwaringAbstract:The arctic and sub-arctic waters of Alaska provide a very hazardous work setting, with special hazards posed by great distances, seasonal darkness, cold waters, high winds, brief fishing seasons, and icing. Our intent is to reduce the remarkably high occupational fatality rate (200/100,000/year in 1991-1992) among Alaska's commercial fishing workers. Over 90% of these deaths have been due to drowning or drowning plus hypothermia, primarily associated with vessel capsizings and sinkings. Comprehensive surveillance for commercial fishing occupational fatalities was established during 1991 in Alaska. During 1990 through 1994, the U.S. Commercial Fishing Industry Vessel Safety Act of 1988 required the implementation of comprehensive prevention measures for all fishing vessels in offshore cold waters, including immersion suits and other personal flotation devices, Survival Craft (life rafts), emergency position-indicating radio beacons, and crew training in emergency response and first aid. Parallel to this, voluntary training efforts by nonprofit organizations have greatly increased. During 1990-1994, drowning was the leading cause of occupational death in Alaska. During this period, 117 fishers died, 101 of them from drowning or drowning/hypothermia. During 1991-1994, there was a substantial decrease in Alaskan commercial fishing-related deaths, from 34 in 1991 to 35 in 1992, 22 in 1993, and 10 in 1994. While man-overboard drownings and some other categories of deaths (falls, fires) have continued to occur, the most marked progress has been in vessel-related events. Specific measures tailored to prevent drowning in vessel capsizings and sinkings in Alaska's commercial fishing industry have been very successful so far. Additional efforts must be made to reduce the frequency of vessel events and to prevent man-overboard events and drownings associated with them.

Probabilistic Analysis of Local Ice Loads on a Lifeboat Measured in Full-Scale Field Trials
Journal of Offshore Mechanics and Arctic Engineering-transactions of The Asme, 2015Co-Authors: Samsur Rahman, Allison Kennedy, Antonio Simoes Re, Rocky S. Taylor, Brian VeitchAbstract:This paper presents an analysis of local ice loads measured during full-scale field trials conducted in 2014 with a totally enclosed motor propelled Survival Craft (TEMPSC) in controlled pack ice conditions. These data were collected as part of an ongoing research program that aims to identify the limitations of conventional TEMPSC operating in sea ice environments and to provide insight as to how these limitations might be extended. During the 2014 trials, local ice loads were measured at two locations on the TEMPSC's bow area. These loads were the most severe measured to date and corresponded to an average ice floe mass that was approximately 1.25 times the mass of the fully loaded TEMPSC. The event-maximum method of local ice pressure analysis was used to analyze these field data to improve understanding of the nature of ice loads for such interactions and to evaluate the suitability of this approach for design load estimation for TEMPSCs (i.e., lifeboats) in ice. The event-maximum method was adapted for the present application, so as to link exceedance probabilities with design load levels for a given scenario. Comparison of the 2014 results with a previous analysis of 2013 field trials data supports earlier conclusions that these interactions are highly influenced by kinetic energy, since more massive ice floes are observed to impart significantly higher loads on the lifeboats. Illustrative examples examining the influence of ice concentration and sail-away distance have also been provided. The work establishes links between extreme loads and the exposure of the lifeboat to ice for different operating conditions. Based on this work it is concluded that the event-maximum method provides a promising approach for establishing risk-based design criteria for lifeboats if field data are available which adequately represent ice conditions encountered during the design life of the lifeboat.

Operability of Lifeboats on Pack Ice: Coxswains’ Skill and Design Factors
OTC Arctic Technology Conference, 2014Co-Authors: Roland Billard, Antonio Simoes Re, Allison Kennedy, Samsur Rahman, Brian VeitchAbstract:The paper describes an investigation into the operability of conventional lifeboats in pack ice conditions. The investigation was based on field trials of a small Totally Enclosed Motor Propelled Survival Craft (TEMPSC) lifeboat that was operated in a range of controlled pack ice conditions. The study focused on observing how operators with different levels of experience and backgrounds operated in ice, how their behaviors impacted their ability to maneuver through the ice field and the impact on the vessel and crew. Participants in the trials had different levels of experience operating in ice and in small Crafts. The coxswains who participated in the investigation had a range of operational experience with vessels in ice, including operators who have worked aboard icebreaking vessels, but with limited experience operating in small vessels, and operators with experience operating small vessels, but with limited experience operating in ice. During the field trials, coxswains employed different tactics for advancing through ice. The outcomes of the study were used to analyze the impact of different driving techniques on the ability of the coxswain to successfully maneuver through ice and the impact of driving style on vessel integrity and crew comfort. The results of the study assess the tactics which can be employed by coxswains in different ice concentrations and the outcomes can be used to define learning objectives for training programs designed to prepare coxswains for emergency operations in ice covered waters.Peer reviewed: YesNRC publication: Ye

Peak Ice Loads on a Lifeboat in Pack Ice Conditions
OTC Arctic Technology Conference, 2014Co-Authors: Allison Kennedy, Antonio Simoes Re, Brian VeitchAbstract:Field testing of a modified Totally Enclosed Motor Propelled Survival Craft (TEMPSC) was conducted in March 2013 in managed level ice conditions. This testing was part of a multi-year trials program, conducted by the National Research Council (NRC), which aims to investigate design considerations for a conventional TEMPSC operating in ice. During the March 2013 testing campaign, the TEMPSC was equipped with a side impact panel and bow visor, both instrumented with load cells to measure local ice impact forces. The resulting local ice load measurements taken during this field trials campaign are presented and the operational performance is discussed. This was the first year during the trials campaign in which local loads on the stem were measured and recorded. The results of this set of field trials could be useful to support the implementation of new TEMPSC design considerations to allow for better performance in harsh, northern conditions. It could also provide operational insight to promote more effective and low stress navigation through ice conditions.Peer reviewed: YesNRC publication: Ye

EVACUATION TRAINING USING IMMERSIVE SIMULATORS
Proceedings of the Eighteenth (2008) International Offshore and Polar Engineering Conference Vol 1, 2008Co-Authors: Brian Veitch, Roland Billard, A. PattersonAbstract:Evacuation by lifeboat is part of the emergency response plan of virtually every offshore petroleum installation and ship in the world. Offshore and marine industry personnel must be competent to operate lifeboats in the weather conditions that prevail during operations, including rough weather. However, it is not practicable to do drills with Survival Craft in even moderately rough weather because the drill itself poses an unacceptable risk to the health and safety of trainees. Further, recent accidents have highlighted the dangers of conducting practice launches even in calm conditions. This gap in training capability is being addressed by innovative simulation-based training for marine evacuation systems that provides training in extreme conditions, but in a safe environment.
