Slow steaming and regulatory drive towards more energy efficient ships have raised a problem of ensuring sufficient manoeuvrability of ships under adverse weather conditions when installed power is reduced. This paper discusses possible criteria for sufficient manoeuvrability in adverse conditions and proposes practical assessment procedure and examples of its application. Further, the paper outlines necessary developments.

The technologies of geodetic works in monitoring of various structures can still be associated with a number of difficulties caused by the influence of different factors despite the studies of many authors on that theme. The article describes the high accuracy geodetic monitoring of the football stadiums "Rostov Arena" and "Kaliningrad" that took place in a short time frame and in adverse weather conditions. The article gives two geodetic monitoring methods such as creating serving network by side-points method and electronic block tacheometry. The technology and the adjustment of measurements made during monitoring are described in the article. The results show that the use of the side-points method and electronic block tacheometry ensures high accuracy measurements even in adverse conditions for observations. Practical conclusions and recommendations are set out. The article may be useful for specialists in the field of monitoring and geodetic control of deformations of structures.

And Performance

It is a well-known fact that the 1989 Exxon Valdez disaster caused the escort towing of laden tankers in many coastal areas of the world to become compulsory. In order to implement a new type of escort towing, specially designed to be employed in very adverse weather conditions, considerable changes in the hull form of escort tugs had to be made to improve their stability and performance. Since traditional winch and ropes technologies were only effective in calm waters, tugs had to be fitted with new devices. These improvements allowed the remodeled tugs to counterbalance the strong forces generated by the maneuvers in open waters. The aim of this paper is to perform a comprehensive literature review of the new high-performance automatic dynamic winches. Furthermore, a thorough analysis of the best available technologies regarding towline, essential to properly exploit the new winches, will be carried out. Through this review, the way in which the escort towing industry has faced this technological challenge is shown.

Detailed Picture

This article examines the travel behavior of middle-class women in Dhaka, the capital city of Bangladesh and one of the world's largest and most densely populated cities. In particular, we focus on women's use of non-motorized rickshaws to understand the constraints on mobility for women in Dhaka. Primary research, in the form of an empirical study that surveyed women in six neighborhoods of Dhaka, underpins our findings. Our quantitative and qualitative data presents a detailed picture of women's mobility through the city. We argue that although over 75 percent of women surveyed chose the rickshaw as their main vehicle for travel, they did so within a complex framework of limited transport options. Women's mobility patterns have been further complicated by government action to decrease congestion by banning rickshaws from major roads in the city. Our article highlights the constraints on mobility that middle-class women in Dhaka face including inadequate services, poorly maintained roads, adverse weather conditions, safety and security issues, and the difficulty of confronting traditional views of women in public arenas.
