The objective of this paper is to apply IMO “severe wind and rolling criterion (weather criterion)” for anchor handling vessels during operation. So far, this criterion is used for merchant ships greater than a certain size and of conventional hull forms but it is not mandatory for special purpose ships ...
ABSTRACT: The whole coastline of Jiangsu province is 954km. It starts north from Xiuzhen estuary, which is the junction of Jiangsu and Shandong province, and south to the north bank of the Yangtze River estuary. According to composition, it can be divided into three categories, including sandy coast, ...
ABSTRACT: In the present work the application of an advanced hydromorphological mathematical model for the design of innovative submerged structures for coastal protection, is presented. Non linear wave transformation in the surf and swash zone is computed by a non-linear breaking wave model based ...
ABSTRACT This paper deals with coupled hydrodynamic analysis between gravity cage and well boat in operation. Dynamic behavior of the moored gravity cage under various current and wave conditions is first simulated, and the sensitivity of mooring line tension to added mass coefficient of the floating ...
ABSTRACT Xiangshan Bay characterized by typical bedrock and silt is a long and narrow coast waters. It is both a traditional shellfish and algae breeding base and a frequent human activity area, where the environmental pollution is increasingly severe. Simulating pollutant transport process and forecasting ...
ABSTRACT Ocean Thermal Energy Conversion (OTEC) can supply stable electric power and a variety of integrated applications. This paper investigates on the thermal performance of Rankine cycle using HFC245fa as working fluid. Rankine cycle was compared among working fluids of different properties that ...
ABSTRACT The practical use of Ocean Thermal Energy Conversion (OTEC) is refocused because it is possible to supply stable electric power and a variety of integrated applications. This paper investigates on the thermal performance of Double Stage-Rankine cycle that has independent equipment respectively ...
ABSTRACT: In the paper, we investigated about the scaling of ecological and economic values in the inclusive impact index Triple I. A new method to calculate γ that converts the economic value to the environmental value was proposed. In the proposed method, the marginal abatement costs of CO2 emission ...
ABSTRACT: In the case of rearing some kinds of fishes that have hiding behavior in the floating aquaculture preserves, a number of fish decreases due to the stress from irregular movement of floating preserves caused by the irregular and continuous ocean waves. Therefore, we developed one method that ...
ABSTRACT: The linear shallow-water equations have been used frequently to simulate transoceanic propagation of tsunamis instead of the linear Boussinesq equations. In previous studies, the physical dispersion is compensated by using the numerical dispersion generated from the leap-frog finite difference ...
ABSTRACT: The international focus for development of wave and tidal energy technologies has been principally on large-scale (MW) devices and grid-connected utility-scale arrays. However, the Pacific Islands present many opportunities for smaller-scale (kW) stand-alone developments. Potential sites ...
ABSTRACT: It was previously mentioned that the mechanical stimulus (touch) caused the active movements of the tunic in Halocynthia roretzi, a solitary ascidian. However, how the direction of the mechanical stimulus is important, and what helps the tunic to have mechanical senses, have not been clear. ...
ABSTRACT: The purpose of this study is to establish the coastal vulnerability index (CVI) of Taiwan coastal area by use of the International Strategy for Disaster Reduction (ISDR) proposed the concept of disaster risk assessment. The vulnerability parameters including of natural environment, life and ...
ABSTRACT: For the implementation of sustainable land development, strengthening ocean, coastal areas resource conservation and management of land use, ""The Draft of National Land Planning Act"" and ""The Draft of Coastal Act"" were performed by Construction and Planning Agency in Taiwan. The utilization ...
ABSTRACT: Based on the control equations consisting of the continuity equation, the momentum equation and realizable k-ε turbulence model, this p ap er introduces the porous media model to establish a two-dimensional numerical model of flow field around fishing net under current. The control equations ...
ABSTRACT: The flow fields around single and two combinations of star shape artificial reefs are investigated both numerically and experimentally. The numerical model is based on the Reynolds Navier-Stokes (RANS) equations embedded with a RNG k-ε turbulence model and SIMPEC algorithm. The governing ...
ABSTRACT: In this study a four cage grid mooring system is presented and a set of equations of motion for this flotation structure are derived. The purpose of this study is to investigate the hydrodynamic behaviors of four-cage grid mooring system under wave actions using numerical model. The numerical ...
ABSTRACT Fishery resources decreased dramatically in North Zhejiang coastal area. It is crucial to picture the pollutant distribution character, to analyze the pollution developing tendency and to identify the pollution origin so as to take effective management measures to reduce the decreasing trend. ...
ABSTRACT We attempted to evaluate the possibility of using Chlorella pynenoidosa to remove ammonia and COD from mariculture effluent through a series of experiments. The results showed that Chlorella pynenoidosa can depend on ammonia as necessary nutrient for growth after the process of domestication ...
