海上保险“仓至仓”责任期间的思考

文中就海上保险“仓至仓”责任期间的起点和终点进行了分析，笔者认为，在海上货物运输保险中，一切险的保险人“仓至仓”责任期间，应起始于被保险货物运离保险单所栽明的起运地仓库或储存处所开始运输之时，而非海运的前一段陆路运输开始之际；终止于货物到达保险单所载明目的地被保险人在桌一处所实际分配、分派货物之时，而非终止于货物到达该处所之际。     

使用“仓至仓”条款需要注意的几个问题

“仓至仓条款”是规范海上货物运输保险中保险人承担保险责任期间的条款,即限定保险责任开始和终止的条款。除战争、罢工等不可抗力的特殊风险外,运输货物保险中的平安险、水渍险和一切险都以“仓至仓条款”限定保险责任。其基本含义是:货物保险人承担“仓至仓”责任,自被保险货物运离保险单所标明的起运地发货人的仓库或储存地开始运输时生效,包括正常运输过程中的海上、陆路、内河运输在内,直到被保险货物抵达保险单所标明的目的地止。但保险人的责任,以被保险货物全部卸离货船后60天为限。 “仓至仓条款”除了将时间概念给予60天限定之外,还对以下几种情况作了规范:     

“仓至仓”条款中保险责任终止问题

保险责任期间是水险赔案争议较多之处，其主要矛盾又体现在责任终止问题上。本文通过解析中国人民保险公司“仓至仓”条款的责任终止形式，指出与此相关的诸多实务问题，并提出了相应的对策和建议。     

超大型沉箱贮仓压力的数值模拟计算

通过ABAQUS有限元分析软件对一般沉箱和超大型沉箱的贮仓压力进行数值模拟,并对比分析数值模拟结果与按现行规范中贮仓压力公式的计算结果。经过对不同参数组计算结果的对比分析后发现:填料的内摩擦角、弹性模量、泊松比,以及填料与仓格边壁间的摩擦系数均是影响贮仓压力的主要参数。现行规范中的贮仓压力计算公式,仅考虑填料内摩擦角和填料与仓格边壁间摩擦系数的影响,而不考虑填料的弹性模量和泊松比影响的假设值得商榷。     

仓泵气力输送试验台设计探讨

对仓泵设计及其控制以及计量中的某些问题进行了探讨。并提出：仓泵中物料在出料口周围局部流态化有利于节能；对空气流量进行控制有利于提高混合比；仓泵中物料动态计量可精确计算瞬时混合比、稳压段输送混合比及总的混合比。试验证明，改进后的仓泵输送可以使物料像脉冲气力输送似的，以疏密状方式在管内呈栓状流动，以达到低速、高浓度、低能耗的目的，而输送距离及输送能力又远大于脉冲等栓状输送，因此具有很大的潜在市场。

有隔墙的圆沉箱贮仓压力数值模拟计算

通过ABAQUS有限元分析软件对圆沉箱弧形仓格、扇形仓格在填料为块石或中砂时,分别进行了数值分析,并对比了数值模拟结果与现行规范矩形仓格的计算结果。分析表明有限元模型计算所得的沉箱中上部水平贮仓压力比规范公式计算值偏小,仓格底部模拟值大于规范公式计算值。工程设计中应将规范公式计算结果适当修正后采用。

Catalyzing Coastal Management in Kenya and Zanzibar: Building Capacity and Commitment

Site-based projects were initiated in Chawka Bay-Paje, Zanzibar, and Nyali-Bamburi-Shanzu, Kenya, to demonstrate the benefits of an integrated coastal management (ICM) approach for addressing coastal issues such as tourism development and enhancement of resource-dependent village economies in eastern Africa. A two-year, multidonor project used three primary strategies to make rapid, but sustainable, progress toward ICM. These included using interagency government teams for ICM planning, adopting an internationally recognized framework for ICM as a project ''road map,'' and explicitly incorporating capacity-building strategies into all aspects of the project. Within two years, integrated ICM action strategies, prepared through participatory processes, were being implemented at both sites, and both teams were working to expand the scale and scope of ICM in their nation. More importantly, the project helped create committed, capable, interagency groups that continue to work together to address urgent ICM issues.     

A simplified method for reliability- and integrity-based design of engineering systems and its application to offshore mooring systems

This paper presents a simplified method for the reliability- and the integrity-based optimal design of engineering systems and its application to offshore mooring systems. The design of structural systems is transitioning from the conventional methods, which are based on factors of safety, to more advanced methods, which require calculation of the failure probability of the designed system for each project. Using factors of safety to account for the uncertainties in the capacity (strength) or demands can lead to systems with different reliabilities. This is because the number and arrangement of components in each system and the correlation of their responses could be different, which could affect the system reliability. The generic factors of safety that are specified at the component level do not account for such differences. Still, using factors of safety, as a measure of system safety, is preferred by many engineers because of the simplicity in their application. The aim of this paper is to provide a simplified method for design of engineering systems that directly involves the system annual failure probability as a measure of system safety, concerning system strength limit state. In this method, using results of conventional deterministic analysis, the optimality factors for an integrity-based optimal design are used instead of generic safety factors to assure the system safety. The optimality factors, which estimate the necessary change in average component capacities, are computed especially for each component and a target system annual probability of system failure using regression models that estimate the effect of short and long term extreme events on structural response. Because in practice, it is convenient to use the return period as a measure to quantify the likelihood of extreme events, the regression model in this paper is a relationship between the component demands and the annual probability density function corresponding to every return period. This method accounts for the uncertainties in the environmental loads and structural capacities, and identifies the target mean capacity of each component for maximizing its integrity and meeting the reliability requirement. In addition, because various failure modes in a structural system can lead to different consequences (including damage costs), a method is introduced to compute optimality factors for designated failure modes. By calculating the probability of system failure, this method can be used for risk-based decision-making that considers the failure costs and consequences. The proposed method can also be used on existing structures to identify the riskiest components as part of inspection and improvement planning. The proposed method is discussed and illustrated considering offshore mooring systems. However, the method is general and applicable also to other engineering systems. In the case study of this paper, the method is first used to quantify the reliability of a mooring system, then this design is revised to meet the DNV recommended annual probability of failure and for maximizing system integrity as well as for a designated failure mode in which the anchor chains are the first components to fail in the system.

Community-Based Management for Sustainable Fisheries Resources in Phang-nga Bay,Thailand

Fishing communities, the Government of Thailand Department of Fisheries, local nongovermnental organizations, universities, the Food and Agriculture Organization of the United Nations (FAO), and FAO's Bay of Bengal Program have undertaken a partnership in management of Phang-nga Bay's coastal resources. It is the first project of its kind in Thailand, and although still in the early stages, offers insights that may contribute to our knowledge of how we can improve our management of coastal resources, including the importance of (1) building relationships within the governance process; (2) combining education, enforcement, and economic incentives to achieve compliance; (3) implementing solutions early; and (4) government support of community-based decisions. These insights reinforce trends emerging in other coastal management projects in the Asian region.
