Abstract

The dry bulk shipping market is highly competitive, with many small-scale ship owners engaging in short-term contracts. However, ship owners often find it challenging to acquire new fixtures after each voyage, and there is a risk of wasting time and cost on looking for a new fixture. This study aims to explore how to improve the use of vessels in the dry bulk spot market by avoiding the risk of wasting time. We construct a database to explore where and when vessels get new fixtures during their voyage by combining the automatic identification system and fixture data. The data shows ships without new fixtures during a previous laden voyage spent more time ballasting than those with new fixtures. For ships without new fixtures during a previous laden voyage, we confirm that the elapsed time from discharge and sailing distance to loading areas are critical for vessels in selecting their next destinations by developing a multinomial logit model. A simple simulation of sailing at different speeds from different discharging ports shows potential strategies, such as vessel speed and direction of the navigation, to improve the probability of getting a new fixture.

期刊介绍： Research in Transportation Business & Management (RTBM) will publish research on international aspects of transport management such as business strategy, communication, sustainability, finance, human resource management, law, logistics, marketing, franchising, privatisation and commercialisation. Research in Transportation Business & Management welcomes proposals for themed volumes from scholars in management, in relation to all modes of transport. Issues should be cross-disciplinary for one mode or single-disciplinary for all modes. We are keen to receive proposals that combine and integrate theories and concepts that are taken from or can be traced to origins in different disciplines or lessons learned from different modes and approaches to the topic. By facilitating the development of interdisciplinary or intermodal concepts, theories and ideas, and by synthesizing these for the journal''s audience, we seek to contribute to both scholarly advancement of knowledge and the state of managerial practice. Potential volume themes include: -Sustainability and Transportation Management- Transport Management and the Reduction of Transport''s Carbon Footprint- Marketing Transport/Branding Transportation- Benchmarking, Performance Measurement and Best Practices in Transport Operations- Franchising, Concessions and Alternate Governance Mechanisms for Transport Organisations- Logistics and the Integration of Transportation into Freight Supply Chains- Risk Management (or Asset Management or Transportation Finance or ...): Lessons from Multiple Modes- Engaging the Stakeholder in Transportation Governance- Reliability in the Freight Sector
