Opis:
Midstream operation (MSO) has played an important role in Hong Kong's port business since the 1960s. MSO has been seriously neglected in maritime transport research in the past. In the course of filling this significant research gap, we aim to address how a new type of harbor vessel – Port Feeder Barge (PFB) can strengthen the sustainability and attractiveness of MSO in Hong Kong and of the port in general. By introducing such type of vessel MSO becomes much safer and faster, much more efficient with less manpower being needed, provides higher flexibility and causes less environmental impact compared to the traditional Hong Kong midstream barges (HK barges). Due to its special layout as a deck carrier the PFB is also very well suited to be optionally fuelled with Liquefied Natural Gas (LNG) which would result into an ultimate "green" harbor vessel. Semi-structured, in-depth interviews with a number of maritime professionals involved in MSO activities in Hong Kong have revealed how PFBs could be employed in MSO, the potential regulatory issues and operating challenges and the critical success factors for further PFB deployment in the Asia-Pacific region. The study provides insights how the PFB could provide notable advantages for a sustainable recovery of MSO in Hong Kong.

Opis:
In the conceptual design of an ecological floating dock, has been assumed to be applied a roof system consisted of six movable segments whose aim is to shelter dock’s working space from environmental influence. The dock has to be also equipped with a gantry crane. Each of the devices is fitted with a traction system whose drive is the subject of this paper. The driving system consisted of synchronous electric motors with external frequency control of their rotational speed, is proposed. Such system may ensure the same rotational speed at both supports, unambiguously determined by voltage frequency and independent of load. The solution could make it possible to avoid dangerous skewing displacements of the structures on rail tracks during service. Additionally, a simplified procedure of determining the main loads necessary for calculation and selection of the devices and traction systems is also presented.
