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.

基于 AIS 的干散货船现货合同地理空间分析
干散货航运市场竞争激烈,许多小船东从事短期合同。然而,船东经常发现在每次航行后购买新的固定装置是具有挑战性的,并且有浪费时间和成本寻找新的固定装置的风险。本研究旨在探讨如何通过避免浪费时间的风险来改善干散货现货市场的船舶使用。我们将自动识别系统和固定装置数据相结合,构建了一个数据库,用于探索船舶在航行中何时何地获得新固定装置。数据显示,在之前的满载航行中,没有安装新固定装置的船只比安装新固定装置的船只花更多的时间来压舱。对于未安装新固定装置的船舶,通过建立多项logit模型,证实了从卸货到装货区域的时间和航行距离对船舶选择下一个目的地至关重要。一个简单的模拟以不同的速度从不同的卸货港口航行,显示了潜在的策略,如船舶速度和航行方向,以提高获得新夹具的概率。

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
