Navigation is a complex interaction between human, organizational, environmental, and technological factors on the ship’s bridge. Today, ships bridges include a broad suite of equipment with both digital and analogue interfaces, covering a range of functions and purposes. Suboptimal usability in equipment and interface design as well as layout of the ships bridge has been reported by researchers for decades. This paper aims to contribute to our understanding of why there has been limited progression in usability in ship bridge design over the last decades, by investigating the stakeholders’ different perspectives of their influence, interest and responsibility for usability in ship bridge design. The study is based on interviews with seafarers, shipowners, equipment manufacturers, shipyard, insurance companies, classification societies and a flag state. Usability in navigational equipment and systems on a ship’s bridge is required by the International Maritime Organization (IMO) SOLAS Regulation V/15. We find that this goal-based requirement is challenging to follow up both in design, development, and survey work. To achieve usability in maritime equipment and bridge systems ideally requires the actively involvement of end-users throughout the design and development process. We find that the seafarers, the direct end-users, do not have a clear voice in the ship bridge and bridge equipment design and the associated purchasing processes. The other stakeholders appear to recognize the existing shortcomings, and some do show interest in improvements, but the responsibility for usability seem to be fragmented, and they see the potential solutions as being somebody else’s problem. We conclude by suggesting both long-term and a short-term way forward for improving usability in ship bridge design.

Ship movement processes in selected Traffic Separations Schemes (TSS) of Southern Baltic Sea were analyzed. Ship domains in the analyzed water areas were calculated from Automatic Identification System (AIS) registered data. The purpose of investigation was identification of ship domain parameters taking into account different domain determination criteria. The results were compared and discussed. The conclusions were drawn.

Zheng He, a famous Chinese mariner, explorer, diplomat and fleet admiral of Ming Dynasty, sailed from China to many places throughout South Pacific, Indian Ocean, Bay of Bengal, Arabian Sea, Pesian Gulf, Red Sea and distant Africa in seven epical voyages from 1405 to 1433, some 80 years before Colubus’s voyages to America on Santa Maria. This magnificent feat in the history of navigation was later considered as a sheer waste of energy and money, and a “failure policy”. The scale of Zheng He’s navigation far exceeds that of Columbus’s “Great Discovery” which followed, but the former had less effect on the progress of the world history. In this paper, we recall Zheng He’s great adventure, as an important waypoint on the passage of navigation history. An introduction to the historical condition of that age and Zheng He’s family background is presented. The fleets, the passages, as well the experiences are illustrated. The shipbuilding technology and science of navigation of China in the ancient period are also demonstrated. And finally we discuss the historical significance, spirit and impact of Zheng He’s sailing. The great voyages are the magnificent landmarks not only in China’s political and diplomatic history but also in navigational annals of the world.
