铝基牺牲阳极在天津港海泥中的应用

由于天津港的回淤性特质,使得一些码头(尤其是老码头)钢结构的牺牲阳极被不同程度的掩埋,导致牺牲阳极阴极保护系统使用寿命和效果降低,从而影响整个码头结构的安全和使用寿命。针对上述问题,提出了一种采用Al-Zn-In-Si系牺牲阳极复合外包填包料的海泥区阴极保护新方法,并将其应用于实际工程中。工程实践表明,该牺牲阳极阴极保护系统的保护效果良好,对解决天津港中被海泥严重掩埋的钢结构的阴极保护具有积极意义。     

天津港岸坡变形观测标准

在天津港地区的码头和防波堤工程建设中,岸坡变形观测一直是一个重要的内容。而对于观测的标准,相应规范中又没有明确的条文规定。通过对天津地区码头岸坡、防波堤、围埝等的观测实践,提出一套观测标准,并结合实际工程进行验证。实践证明,这套标准是可行的。在今后的工作中,可以推广应用并进一步完善。     

计算机联锁系统在黄骅港港区铁路扩容工程中的应用

为提升港口铁路系统的列车运输能力和信号设备的安全性,在黄骅港港区铁路扩容工程中,港区站采用计算机联锁系统取代传统的电气集中联锁系统,在区间采用先进的移频自动闭塞系统,并在港区站采用微机监测系统进一步提高了信号设备的安全性和可靠性,对改善与优化港区站场信号系统具有重要意义。

潍坊港沉积物特征及岸滩稳定性研究

通过潍坊港海岸动力地貌调查,分析研究了潍坊港各港区的水下沉积物分布特征。近岸沉积物质主要表现为极细砂与砂质粉砂,源于历史上黄河及附近河流的泥沙,中值粒径大致在0.01～0.4 mm,分选程度为分选好-中常。通过不同历史时期海图的等深线和断面海床冲淤变化对比,分析认为,潍坊中港区以西,受黄河口泥沙扩散、沉积影响,海床一直处于持续淤涨之中,这种趋势还将持续,潍坊中港区以东海床则基本保持稳定。从黄河口流路变迁这一角度来看,该海区岸线将在长期内保持稳定。     

政府投资项目HPC模式的探讨

目前大多数政府投资项目已经不再拘泥于传统的管理组织模式,而是逐渐融合多种项目管理经验,发展适应于具体项目的组合模式。现实中,组合模式的开发存在多重困难,如何正确地运用组合模式也是项目管理必须面临的一大难题。此文对政府投资项目HPC模式进行探讨,并进行治理分析。     

Simulation-based severe weather-induced container terminal economic loss estimation

Container terminals play a critical role in maritime supply chains. However, they show vulnerabilities to severe weather events due to the sea–land interface locations. Previous severe weather risk analysis focused more on larger assessment units, such as regions and cities. Limited studies assessed severe weather risks on a smaller scale of seaports. This paper aims to propose a severe weather-induced container terminal loss estimation framework. Based on a container terminal operation simulation model, monthly average loss and single event-induced loss are obtained by using historical hazard records and terminal operation records as model inputs. By studying the Port of Shenzhen as the case study, we find that the fog events in March lead to the longest monthly port downtime and the highest monthly severe weather-induced economic losses in the studied port. The monthly average loss is estimated to be 30 million USD, accounting for 20% of the intact income. The worst-case scenario is found to be a red-signal typhoon attack which results in nearly 20% decrease in the month’s income. The results provide useful references for various container terminal stakeholders in severe weather risk management.     

Port-city exhaust emission model: An application to cruise and ferry operations in Las Palmas Port

Exhaust emissions cause air pollution and climate change. The exhausts of shipboard fuel combustion are equally damaging particularly, so close to the environmentally sensitive mainland and island coasts, as well as at ports due to their urbanized character. This paper estimates, for the first time, exhaust pollutants related to cruise and ferry operations in Las Palmas Port and, in an island context. Emission assessment is based on a full bottom-up model and messages transmitted by the Automatic Identification System during 2011. Results are described as a breakdown of NOx, SOx, PM_2.5, CO and CO₂, according to ship classes, operative type and time, providing valuable information to environmental policy makers in port-city areas and islands under similar conditions. It is generally concluded that vessel traffic and passenger shipping in particular are a source of air pollution in Las Palmas Port. Emission maps confirm location of hot spots in quays assigned for cruise and ferry operations. Policy recommendations encourage regular monitoring of exhaust emissions and market-based incentives supported by details on polluting and operative profiles. On the other hand, feasibility studies are suggested for automated mooring, LNG bunkering facilities and also shore-side energy services, prioritizing berthing of shipping sectors (or sub-sectors) with the highest share of exhaust emissions once their local effects have been confirmed by a dispersion, exposure and impact assessment.
