航运企业投资对码头运营效率的影响研究

随着港口投资结构多元化、航运企业向综合物流商转变,“港航合一”成为航运业未来的发展趋势.在此背景下,研究航运企业投资对码头的影响能够为码头健康发展提供一定的理论依据.本文先采用三阶段DEA模型对我国沿海集装箱码头2008–2012 年间的运营效率进行测度,其次依据投资结构将我国沿海62 个集装箱码头进行分组,最后重点分析投资结构与码头运营效率之间的关系.研究结果显示,有航运企业投资的码头运营效率普遍高于无航运企业投资的码头,两组码头的纯技术效率相差较小,而规模效率相差较大.航运企业参与码头建设经营可以实现自有船舶挂靠自有码头,提升码头设施的利用率,从而提升码头的规模效率,有利于码头的健康发展.     

液体化工品运输码头职业病危害调查分析

液体化工品运输码头职业健康管理尚处于起步阶段,为掌握行业从业人员的职业健康现状,提升从业人员职业健康管理水平,以某企业配套液体化工品运输码头为调查对象,根据国家有关职业卫生标准,采用现场职业卫生学调查与工作场所职业病危害因素检测相结合的方法,识别该码头职业病危害因素,检测危害程度,分析职业病致病因素。调查结果表明,该码头职业健康总体情况基本良好,但噪声指标轻微超标,有个别从业人员耳塞佩戴不正确,建议通过改进防护技术、加强行政管理等手段进一步提升码头职业健康管理水平。     

A case study related to the improvement of working and rest hours of oil tanker deck officers

Navigation safety on coastal waters is an extremely important issue. Fatigue is an important factor threatening navigation safety. Considering that the vessel type is an oil tanker, such a threat is not posed only to the crew but also to the environment. Most of the tankers navigating coastal waters are in the small tanker category. Therefore, this study examined the working and resting hours of the deck officers in the oil tankers navigating coastal waters. The study utilized the ISF Watchkeeper 3 program for assessing and interpreting the working periods. The study reached the conclusion that the first and second officers in particular are working under unsuitable conditions. To improve the working conditions of the deck officers, effects of additional cargo officer on board was investigated. This study is in quality of recommendation. The study elucidated that the cargo officer practice determines the working and resting hours of deck officers, in the work on the oil tankers, and compliance with the related conventions.     

Maritime logistics as an emerging discipline

The evolution of maritime logistics as an emerging discipline has resulted, to a large extent, from the increasing and varied demands of shippers and customers and the rapidly changing role of ports in the context of supply and logistics chains. Scholars are becoming increasingly aware of the need to integrate logistics and supply chain management concepts in the maritime transportation chain and operations. This article aims to provide a review and foundation for understanding the domain of maritime logistics and to assess its potential as an emerging discipline. To do so, a framework for understanding the various aspects of maritime logistics strategy and implementation is developed. A synthesis of the existing knowledge on maritime logistics is done by integrating diverse explorations forming the basis of this framework. We draw upon the literature on maritime transport and ports and primarily theliterature that analyses concepts by adopting an economic or management perspective.     

Advances in port studies: the contribution of 40 years Maritime Policy & Management

Port economics, management and policy have progressively emerged as a distinctive research field, and a core part of maritime economics. This paper provides an analysis of all the 267 port studies published in Maritime Policy & Management (MPM) since its inception in 1973. This paper provides a content analysis for seven interrelated research theme categories including main research topics and methods, authorship distribution and citation counts. It is demonstrated that MPM played, and continues to play, a key role in publishing research on seaports. The published research increasingly applies established analytical frameworks to ports. The paper concludes with a discussion on current challenges for port-related research.     

The Methodologies of Empowerment? A Systematic Review of the Deployment of Participation in the Coastal Zone Management Literature

Participation (e.g., stakeholder involvement) has become a central concept in the practice of environmental and coastal zone management. Research has shown that the integration of participation in coastal zone management has positive ecological and social outcomes. In the literature, however, participation is often reported in an unstructured and uncritical manner. Therefore, to find out whether and how there is a useful way to structure and characterize the way the coastal zone management literature deals with participation, we have conducted a literature review. The review was conducted and the literature structured through three central dimensions of participation, namely: power, knowledge, and (visions of) nature. The article concludes that this structured approach to participation enables us to study more systematically the role of participation and might facilitate the governance and learning processes of coastal networks.     

Managing Shoreline Change Under Increasing Sea-Level Rise in Ghana

Relative sea-level rise will affect vulnerable coastal communities globally. Quantifying this effect on the coastal environment and infrastructure provides critical information that enables coastal managers to develop sustainable mitigation and adaptation measures. Modeling applications have enabled the past, present, and future trends in shoreline morphology to be investigated in detail. Predictive numerical models depend largely on the reliability of the input data. This article reports on using the Soft Cliff and Platform Erosion (SCAPE) numerical model to simulate future shoreline evolution trend in the central Accra coast in Ghana. The model input parameters include historic shoreline recession rates, wave data, tidal data, bathymetry, beach volume, beach topography, historic relative sea-level rise rates, and the shoreline orientation. The data fed the SCAPE numerical model which simulated the emergence of soft rock shore profiles over timescale of decades to centuries, to project future positions of the central Accra shoreline for the next 100 years under different scenarios of climate change. Simulated future shoreline positions overlaid on a 2005 orthophoto map of Accra enabled vulnerable areas and infrastructure at risk to be identified. It emerged that a highly populated community in central Accra will be inundated by 2065, while the Rivera beach resort will be eroded from 2035. A natural fish landing site in Osu (suburb in Accra) will be lost from 2045. The study has demonstrated that considerable ecological, economic, social, and national losses should be expected within the next century. Shoreline change management options should be explored to help mitigate the expected impact of the sea-level rise.     

Use of GIS-Based Models for Integrating and Developing Marine Fish Cages within the Tourism Industry in Tenerife (Canary Islands)

Site selection is a key factor in any aquaculture operation, affecting both success and sustainability. Moreover, it can solve conflicts between different coastal activities, making a rational use of the coastal space. Geographical information systems (GIS) have become of increased significance for environmental planning and assessment mainly because of the need to compare a great number of spatially related data, and because it can be used to couple these spatial data with their attributes and overlay them. This study used GIS and related technology to build a spatial database using those criteria which were considered to have any influence in integrating marine fish-cage culture within the tourism industry in Tenerife. Criteria were grouped in three submodels (distance to beaches, nautical sports, and viewshed), which were combined to generate a final output showing the most suitable areas for cage culture development in coexistence with tourism. Most areas of the coastline of Tenerife were identified as being suitable (56%) or very suitable (46%), suggesting that marine cage aquaculture could be developed on the island in coexistence with the well-established tourism industry.     

Financing Beach Improvements: Comparing Two Approaches on the Georgia Coast

Fifty-five percent of Georgia's developed coastline has been armored with various types of erosion protection devices. This article is about beach improvement projects at Jekyll Island that would operate under (a) a nourishment policy or (b) a retreat policy. Benefits are calculated from an intensive, on-site survey of beach visitors and the costs are calculated from observable sources. Two financing methods are considered: general revenue and user fee financing. The analyses imply recommending beach improvement as an effective policy within the considered time frame.
