One of the most urgent environmental problems facing the shipping industry today is the reduction of Greenhouse Gas (GHG) emissions from its operations and the possible cost-effective ways in which this reduction could be accomplished. Various technical and operational measures have been proposed as well as market-based instruments for the achievement of the compliance of marine industry with these measures. This paper investigates the levels of environmental awareness of the Greek shipping companies and their views and practices on the proposed policies for the reduction of GHG emissions from their ships. A survey was carried out using a questionnaire distributed to Greek shipping companies of different sizes, involved in different segments of the marine industry, so that the survey's results not only represent a large part of the Greek shipping industry but also reveal the different environmental attitudes and practices on maritime GHG emissions among the shipping companies. Given the size and the importance of the Greek shipping industry in the international maritime field, this paper's results present a special significance as they could be further analyzed and taken into account for the achievement of the compliance of marine industry with any future policy instrument for the reduction of maritime GHG emissions. 相似文献

A prominent feature of modern day piracy is the ransom that is demanded for the safe release of the ship, cargo and crew.
The recent upsurge of this type of piracy, in areas of the world that are of strategic importance to the shipping industry,
has created many challenges for shipowners, underwriters and the law relating to marine insurance. The aim of this paper is
to examine how the marine insurance market is being affected by the threat of modern day piracy, and seeks to identify the
options that are available for the recovery of a ransom payment by the shipowner. Moreover, this study aims to identify the
legal issues that might prevent a shipowner from recovering a ransom payment under an insurance policy or from the other interests
in a common adventure. The study establishes that a reasonably made ransom payment by the shipowner will amount to an extraordinary
expense that is taken to minimise or avert a loss. Such an act can generally be recovered under the insurance policy as a
sue and labour expense or from other interests in the common adventure as a general average expense. However, illegality,
unseaworthiness and exemption clauses in a marine policy are identified as being legal issues that may prevent a shipowner
from recovering the ransom payment. Some of these problems may be overcome if clauses are carefully drafted to specifically
cater for modern day piracy in a marine insurance policy. Several inconsistencies may also be resolved by transferring the
piracy peril to war risks cover. The shipowner’s duty is to respond to the changing circumstances, by ensuring that his vessel
is sufficiently equipped and the crew is properly trained to resist a hijacking. 相似文献

The ecosystem function of the oligotrophic Cretan Sea is explored through the development and application of a 3D ecological model. The simulation system comprises of two on-line coupled submodels: the 3D Princeton Ocean Model (POM) and the 1D European Regional Seas Ecosystem Model (ERSEM) adapted to the Cretan Sea. For the tuning and initialisation of the ecosystem parameters, the 1D version of the biogeochemical model is used.After a model spin up period of 10 years to reach a quasi-steady state, the results from an annual simulation are presented. A cost function is used as validation method for the comparison of model results with field data. The estimated annual primary and bacteria production are found to be in the range of the reported values. Simulation results are in good agreement with in situ data illustrating the role of the physical processes in determining the evolution and variability of the ecosystem. 相似文献
