Vessel traffic service systems: cost-recovery alternatives

This paper investigate cost-recovery alternatives for US federally-operated vessel traffic service (VTS) systems. These include those currently used or have been used by VTS and 'VTS-like' systems and other feasible, but not used herefore, alternatives, a federal trust and a federal VTS user-fee structure. Three federal trust funds exist whose waterway-related earmarked revenues could also be earmarked for VTS systems. A federal VTS user-fee structure while raising revenue to finance VTS systems is not expected to be detrimental to the competitiveness of VTS ports nor to the vessel operators that call if their cost-savings exceed fees paid.     

Potential and benefits of AIS to Ships and Maritime Administrations

The Universal Automatic Identification System (AIS) provides a huge variety of potential applications and services which exceed the well known ship-to-ship data exchange. The purpose of this paper is to address the most important AIS services, in particular the AIS position report and the AIS safety-related and binary messages (“AIS telegrams”). The main issue is the impact of this new technology on the on-board use of AIS in collision avoidance (and its limitations) as well as the impact on shore-based services such as Vessel Traffic Service (VTS), port management and the need of an effective AIS network.     

Organizational change for port authorities: a social information processing analysis

Port authorities, like other organizations, have been constantly required to evolve in response to business, environmental, and technical changes since the 1980s to continue improving their competitiveness and performance. However, people often resist change due to various reasons, and the uncertainty of change has been pointed out as one of the most important reasons why this happens. This study contributes to social information processing (SIP) research and constructs an SIP model to explore employee’s response to port organizational reform in Taiwan. Empirical results are consistent with general job schema, where employees with job security orientation are less supportive of port corporatization, and those with corporate development orientation are more supportive of port organizational reform. Organizational trust and job conception are related to port workers’ attitude to port corporatization. Nevertheless, organizational communication does not positively moderate the relationship between job schema and employee attitude to port organizational change.

The relationship between maritime education and employer trust: the structural equation modelling (SEM) perspective

The research is aimed to identify factors in the maritime education and training (MET) system and its relationship on maritime labour employers’ (MLEs) trust based on current practice in Malaysia. A questionnaire survey was used, and the respondents were the participants of a related conference in Malaysia. The structural equation modelling technique was used to explain the relationships in the stipulated research model. The test of structural model confirms that the model is adequate in explaining the MLEs’ trust. The results reveal that the perceived MET institutions’ efficiency has significant direct effects on the MLEs’ trust and the perceived seafarers’ competency. In addition, the perceived implementation of International Convention was found to significantly affect the seafarers’ competency. However, the perceived seafarers’ competency was not found to directly affect the MLEs’ trust. This study suggests that the MLEs’ trust is an important indicator and feedback on it can be used to further enhance the current MET system and its policies. Thus, one of the strategies is to develop a policy in order to achieve an effective maritime education and training. This is to support the maritime communities in progressing towards a more sustainable development in the MET in the context of enhancing the maritime safety.

Policy making and planning for the port sector: paradigms in conflict

The UK has a requirement for people with seafaring expertise to fill a wide range of jobs in the maritime-related sector of the economy ashore. The pool of seagoing ships' officers has now reached the level where shore-based demand for such officers cannot be satisfied by natural wastage from this pool alone. This paper considers the implications of this for the Government's recently announced strategy for maintaining the maritime skills base. The paper concludes that it is inevitable that the Government's present strategy will fail, and suggests what measures need to be taken if the skills base is to be saved.
