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.     

Present pilotage practices in Finland

Pilotage has been studied very little internationally and also in Finland. However, accidents in which pilots have been involved have been investigated thoroughly. Studies show that the traditional individual-centred pilotage with non-written passage plans no longer serves the needs of today's traffic and vessels that have increased in size. Pilotage should be based on the so-called good pilotage practices, i.e. pre-prepared, yet adaptable passage plans, more efficient bridge co-operation and modern navigation instruments. Yet, these are not an integral part of the prevailing pilotage practices in Finland. Pilotage should be developed so that the safety management systems of the vessels support the co-operation on the bridge, but on the other hand, so that the advantages of today's pilotage practices are maintained.     

Ability of a “minimum” microbial food web model to reproduce response patterns observed in mesocosms manipulated with N and P, glucose, and Si

We compared an idealised mathematical model of the lower part of the pelagic food web to experimental data from a mesocosm experiment in which the supplies of mineral nutrients (nitrogen and phosphorous), bioavailable dissolved organic carbon (BDOC, as glucose), and silicate were manipulated. The central hypothesis of the experiment was that bacterial consumption of BDOC depends on whether the growth rate of heterotrophic bacteria is limited by organic-C or by mineral nutrients. In previous work, this hypothesis was examined qualitatively using a conceptual food web model. Here we explore the extent to which a “simplest possible” mathematical version of this conceptual model can reproduce the observed dynamics. The model combines algal–bacterial competition for mineral nutrients (phosphorous) and accounts for alternative limitation of bacterial and diatom growth rates by organic carbon and by silicate, respectively. Due to a slower succession in the diatom–copepod, compared to the flagellate–ciliate link, silicate availability increases the magnitude and extends the duration of phytoplankton blooms induced by mineral nutrient addition. As a result, Si interferes negatively with bacterial consumption of BDOC consumption by increasing and prolonging algal–bacterial competition for mineral nutrients. In order to reproduce the difference in primary production between Si and non-Si amended treatments, we had to assume a carbon overflow mechanism in diatom C-fixation. This model satisfactorily reproduced central features observed in the mesocosm experiment, including the dynamics of glucose consumption, algal, bacterial, and mesozooplankton biomass. While the parameter set chosen allows the model to reproduce the pattern seen in bacterial production, we were not able to find a single set of parameters that simultaneously reproduces both the level and the pattern observed for bacterial production. Profound changes in bacterial morphology and stoichiometry were reported in glucose-amended mesocosms. Our “simplest possible” model with one bacterial population with fixed stoichiometry cannot reproduce this, and we suggest that a more elaborate representation of the bacterial community is required for more accurate reproduction of bacterial production.     

Incident reporting in Finnish shipping companies

The purpose of the International Safety Management Code (the ISM Code) is to promote safety culture in the maritime industry. Learning the lessons from incidents should help to improve safety performance since incidents and accidents can share the same root causes. The aim of this paper is to take a closer look at incident reporting in the Finnish shipping industry, to study the reasons for poor incident reporting and to suggest improvements to increase reporting. The paper consists of a literature study, which focuses on previous studies concerning incident reporting, and an interview study, which focuses on Finnish shipping companies and their personnel. The interview study confirmed that incident reporting does not function properly within the Finnish maritime industry. The maritime personnel have an occupational culture which is incompatible with the rule-based safety management approach provided by the ISM Code. The willingness to report incidents could be increased if all seafarers were involved in the reporting process and the preparation of corrective actions. In addition, the reporting procedures should be streamlined and developed to a more user-friendly direction.     

Evaluation of maritime safety policy instruments

This paper analyzes the effectiveness of the current maritime safety policy system as a whole. It offers an overview of different kinds of policy instruments that are used to enhance maritime safety and the criteria for effective policy instruments. It provides a criticism and goes through the weak points of the current maritime safety policy system, and finally, the system is analyzed in the light of the criteria for effective policy. The paper is based on literary sources, mainly on articles published in academic journals. The conclusion of the article is that the development of individual policies will not greatly improve the current level of maritime safety, and more fundamental changes are needed in the governance of maritime safety.
