Opis:
South Louisiana is undergoing rapid land loss and the construction and utilization of navigation channels by the offshore oil and gas industry, the commercial fishing industry, the oil refining industry, and freight shippers is one cause. A network of natural and man-made navigation channels support commerce and industry throughout the region, but no quantitative information is available on the users of the channels and their contribution to land loss. The purpose of this note is to characterize utilization across eight channels in South Louisiana using data from the Automatic Identification System. Approximately 125,000 vessels used the channels over a two year period between 2011-2012. The Mississippi River was the most heavily utilized channel with an average of 345 vessels per week across the report zone, followed by Bayou Lafourche and Sabine Pass with about 195 vessels per week. The oil refining industry was the primary user of the Calcasieu and Sabine Pass channels while the freight industry was the primary user of the Mississippi River. The offshore oil and gas industry were the primary users of Bayou Lafourche, the Houma Navigation Canal, the Atchafalaya River and Freshwater Bayou.

Opis:
The high rates of casualties in bulk carrier shipping have attracted a worldwide concern for safety and regulatory control from numerous governmental and private agencies. Between 2011 and 2020, a total number of 34 bulk carriers’ ships has been identify as total loos, resulting to the death of 128 seafarers. In this study, the statistically analysis of bulk carrier accident occurring from 2011 to 2020, in terms of their frequency, types of accident, locations of incidents and the factors that influence their occurrence has been reviewed. This study will contribute to decision-making and guidance on rational safety resource allocation that will help reduce the high casualty rates in bulk carrier.

Opis:
This study takes its departure in the difficulties to recruit and retain qualified senior seafarers in the Swedish shipping sector. The study focus is on seafarers’ motivation at work for the specific shipping company (organizational commitment), and seafarers’ motivation towards their occupation (occupational commitment), in times of flagging out. It was hypothesized that the youngest seafarers and the oldest may be most sensitive to foreign registration of ships. Statistical analyses were employed, using a survey material of 1,309 Swedish seafarers randomly collected in 2010 from a national register of seafarers. The results of the analyses show that flagging-out imposes a significant decline in organizational commitment for all seafarers. This decline is related to the perception of the social composition of crew. In addition, the oldest seafarers (age 55+) demonstrate diminished occupational commitment under a foreign flag. This decline is related to the degree of satisfaction with the social security structure. Occupational commitment among the youngest seafarers (age 19-30) is not affected by the nationality of flag. However, this type of commitment is decreasing by the time served on the same ship. This effect is partly related to a decline in satisfaction with the work content. In the concluding discussion, the findings are discussed in more details and recommendations are put forward.
