This study introduces the Three-Memory-Model (Cherry, 2019) in education into Maritime Simulator- based training in Sri Lanka and conducts empirical research. In simulator-based education what is disseminated as knowledge during the Briefing, Scenario and Debriefing phases must be transferred from short-term, across working memory to long-term-memory. Working memory gained during the scenario phase, could be encoded into long-term-memory through rehearsal probes. But the number of probes which could be tolerated by the participants of simulator-based training has not undergone empirical investigation. Thus, selecting the Open Sea scenario phase as its setting the research questions aim to identify tolerance limits in the participants for the number of freezes and the number of probes introduced during each freeze. The methodology selects a population of seafarers (n = 60). Through stratified random sampling this population was subdivided based on experience at sea as Group A (n = 30): Mean of 2 years and Group B (n = 30): Mean of 13.6 years of sea experience. The duration of the open sea scenario phase is 35 minutes with freezes at 10-minute intervals. The number of probes were given a range of 7 to. Data analysis utilized SPSS. The highest percentage mean value was obtained for three freezes for the Open Sea scenario phase while two freezes had the next highest percentage mean value. The mean value of the tolerance limits for questions during one freeze is approximately 9 and 6 probes for Group A and B respectively. Citing prior research on working memory, visuo-spatial vs. verbal working memory, reaction time and age this study raises a counter argument against the findings: the self-declared tolerance limits of the number of questions the participants feel comfortable to answer during each freeze. The findings of this research are valuable to maritime Simulator-based instructional designers outside and within Sri Lanka.

Unlike accidents on land, marine accidents can not be supported rapidly from the outside. For this reason, The initial response and damage control system are critical. Cruise Lines International Association (CLIA) reported the necessity of the damage control system to IMO in the early 2000s. Even though the installation of these systems is not compulsory, the damage control system is installed and operated in about 60 cruises. The key component of damage control system is supporting the decision-making using 'KILL Card'. The purpose of study is to develop the shipboard training scenario for the foundation of 'KILL Card'. We made scenarios for fire and flooding through the analysis on existing scenarios, marine accident case and relative regulation. The suggested shipboard training scenario based on damage control system enables the crew to response with rapid decision-making to damage in emergency situations.

In spite of international efforts to control nuclear weapons and chemical, biological, and radiological (CBR) weapons, North Korea obtains and sells CBR weapons illegally. As a result, the worldwide threat of CBR weapons is increasing. Unfortunately, civil defense education and training for CBR weapons have not been adopted for real situations because of the long period of absence of an actual combat. In this study, virtual training scenarios that are applied to the simulation were made in 5 steps to cope with CBR situations. These scenarios are expected to have three effects. First, trainings can be improved with experience and education. Second, the problems and health hazards of CBR weapons and supplies can be solved with CBR virtual training simulation experience. Finally, corresponding effects can be recognized and predicted in real situations through roles and mission procedures of simulation scenario.
