定期租船是出租人(通常是船东)经营船舶的主要方式之一.和航次租船相比,定期租船的优点在于出租人可以省去许多诸如揽货、订舱、营运调度、港口代理等环节,通过定期收取租金而取得稳定的利润.可以想象,船舶期租给一个实力强、信誉好的承租人经营,对出租人来说,通常可以获得稳定可观的利润. 相似文献

ABSTRACT Due to the outstanding strength of advanced machine-learning techniques, they have become increasingly common in predictive studies in recent years, particularly in predicting ship energy performance. In constructing predictive models, prior studies have mostly employed vessels’ technical parameters to establish machine-learning algorithms. To bridge this research gap and enable wider applications, this paper presents the design of a multilayer perceptron artificial neural network (MLP ANN) as a machine-learning technique to estimate ship fuel consumption. We utilized the real operational data from 100–143 container ships to estimate fuel consumption for five different container ships grouped by size. We compared the performance of two ANN models and two multiple-regression models. Four input parameters (sailing time, speed, cargo weight, and capacity) were included in the first ANN and the first regression model, while the other two models only consider two inputs from physical function. The mean absolute percentage error of the ANN models with four inputs was the smallest and less than those in extended statistical models, demonstrating the MLP’s superiority over the statistical model. The MLP ANN model can thus be applied to confirm the effectiveness of the slow-steaming method for achieving energy efficiency. 相似文献

ABSTRACTAccurately estimating fuel consumption of ships is crucial for shipping companies, port authorities, and environmental protection agencies. The bottom-up approach is becoming increasingly popular because it can estimate ship fuel consumption by accounting for ship activity conditions, such as changes in voyage speed, time, and distance; however, its use is still limited when estimating ship fuel consumption. Ship-specific information, such as the daily fuel consumption rate for main and auxiliary engines for every vessel, is expensive to gather, and generally not collected from private shipping companies. To address this research gap, we develop simplified and composite ship fuel consumption models for ocean-going container ships by size using a regression model. To estimate the fuel consumption models for container ships, we rely on ship activity data, including average speed and sailing time, distance, and actual fuel consumption for main and auxiliary engines. This information is obtained from a major container shipping company in Korea. We estimate and validate the parameters associated with fuel consumption for five different container ship sizes, all of which are smaller than the Post-Panamax container ship (15,000 TEU and above). 相似文献

非自航工程船舶锚泊设备配置计算探讨 总被引:2,自引:0,他引:2
随着深水港口建设的发展,外海施工项目日益增加,非自航工程船舶按照常规配置的锚泊设备已不能完全满足水上锚泊安全及移船作业需要。合理地配置、应用锚泊设备,将会有效地改善非自航工程船舶在深水海域的锚泊安全和移船作业效率。笔者根据非自航工程船舶锚机配置现状,对其合理性和安全性,通过对比分析和计算做些探讨。旨在从设备配置上进一步提高船舶安全作业能力。 相似文献
