Review of pilotage processes and indicators in pilotage organisations

A questionnaire survey was conducted to find out how pilotage organisations in different countries assess and measure the quality, efficiency and safety of their operations. An e-mail survey was sent to 54 pilotage organisations in Australia, Canada, and Western and Northern Europe. All International Standard for Maritime Pilot Organizations (ISPO) members were also included. The survey yielded 13 answers from eight countries. The organisations were questioned about their standards and management systems, standard operating procedures and measuring tools. According to the query, most of the pilotage organisations use standard-based management systems such as ISO 9001 or the ISPO. The main measuring tools for pilotage comprise of statistical information concerning pilotage and the organisations, customer feedback surveys and financial results. The results of the survey were used as a guideline for developing a pilotage process model and indicators for measuring the effectiveness and quality of the pilotage process for the Finnish pilotage company Finnpilot Pilotage Ltd.

Do port security quality and service quality influence customer satisfaction and loyalty?

ABSTRACT

This study uses Kaohsiung Port as a case study to evaluate the relationships between port security quality, port service quality, customer satisfaction, and customer loyalty. For this purpose, a survey was conducted with shipping companies and freight forwarders in Taiwan. The results indicate that port security quality has a direct and positive impact on both port service quality and customer satisfaction; port service quality has a direct and positive impact on both customer satisfaction and customer loyalty; and customer satisfaction has a direct and positive impact on customer loyalty. However, the impact from port service quality is more significant than that of port security quality. Accordingly, this study suggests that Kaohsiung Port should concentrate on improving its service quality in order to enhance customer satisfaction and customer loyalty.

Household attitudes toward environmental quality in a coastal South Carolina County

Abstract

This paper presents an analysis of the findings of a survey of a sample of Beaufort county, South Carolina, households which was conducted to ascertain preferences for environmental quality. These preferences were approximated from survey responses on willingness to pay for environmental amenities and the size of payments households would require to forfeit them. A scale was developed and used to rank these responses ordinally, and the matrices of scaled responses for each of eight household annual‐income classes were subjected to factor analyses.

Testing the SERVQUAL scale in the passenger port industry: a confirmatory study

A key question is whether the service quality instruments developed for other services’ industries may be used to gauge service quality perceptions in shipping. Grounded on similar studies that test the most widely used American service quality instrument, SERVQUAL, in the commercial shipping sector, this study examines its applicability in the passenger shipping realm. Based on a survey of 436 passengers in Piraeus port, SERVQUAL's five main dimensions have been checked regarding their fit with the use of Confirmatory Factor Analysis. Results support that this is a valid instrument for measuring service quality in passenger shipping besides certain considerations regarding its dimensionality. A more parsimonious two-factor model seems more applicable and should therefore be also considered. Finally, it is evident from the study that passengers place more importance to the physical than the interactive elements of service to form their overall satisfaction.
