ABSTRACT Corrosion in seagoing vessels is an unavoidable phenomenon which affects the physical life and safety of the hull structures. Conventionally corrosion margins are introduced to cope with the problems of corrosion and wear. Since the phenomena of corrosion and wear of structural hull members ...
ABSTRACT In this paper, the KCS is considered as the parent ship. The single-objective genetic algorithm is taken as the optimization technique leading to an optimal ship considering full speed range. In order to validate and analyze the optimization results, numerical calculation of the optimal ship ...
ABSTRACT Seakeeping is a key standard to examine whether a ship has good performance in waves. Ship hull forms can significantly affect the motion behavior in waves and the influences vary a lot under different wave conditions. Therefore, it is necessary to conduct the multiobjective optimization design ...
ABSTRACT An improved numerical method for calculation of icebreaking force is proposed in this paper. First, the dynamic bending failure criterion is introduced considering the loading rate, which is of great significance to the icebreaking process. The parametric expression of the dimensionless coefficient ...
ABSTRACT Time domain ship motion based on 3D Transient Green's Function method (3DTGF) is established, in which the impulse response theory is employed and the memory effect part of hydrodynamic forces is solved by 3DTGF incorporated with high-order boundary element method (HOBEM). The motions of Wigley-III ...
ABSTRACT In recent years, with the increasing of the ship size, the ship propulsion should transfer more torque and thrust than before to guarantee the normal operation during the ship navigation which could cause severe vibration of the shaft. For the large vessels, the ship hull is always regarded ...
ABSTRACT The attachment of marine fouling organisms is harmful to any marine structure such as ship hulls, fishing nets, jetties and platforms. Marine antifouling coating is still the widely commercial used solution for marine antifouling in shipping industry. It is necessary to evaluate the antimicrobial ...
ABSTRACT Collision accidents between ships often result in serious loss of economic and life, hence it is vital to research the collision resistance of protective structures. Relative to the convention structure of stiffened panels with flat-bar, angle-bar and tee bar that are generally adopted as ...
ABSTRACT This study aims to evaluate the influence of pile driving noise through broadband large-area simulation for the potential offshore wind farms (OWFs) in Changhua County, Taiwan. The underwater noise simulation is based on the Range-dependent Acoustic Model (RAM) and ocean environmental inputs ...
ABSTRACT Aquaculture of Atlantic salmon in coastal and offshore locations is an operation intensive industry. This paper gives an overview of the most typical marine operations in the aquaculture of Atlantic salmon. Descriptions of these operations are introduced in the first place, which is followed ...
ABSTRACT In the paper, economic impacts on China's various maritime industries within two years were simulated based on the input-output model (IO model) in economics and input-output tables. As analysis, the sea ice disaster in the winter from 2009 to 2010 caused a total direct economic loss of 6.318 ...
ABSTRACT This study aimed to research the morphological changes around the coastline adjacent to the Hsinchu Fishery Port, one of the 13 hot spots of massive morphological changes in Taiwan announced by the Ministry of the Interior, Taiwan. The trend of coastal change could be understood via the sediment ...
ABSTRACT A huge number of marine (coastal and offshore) structures of different types, floating or fixed, and of various sizes have been constructed and installed worldwide. The state of a marine structure during its life cycle must remain in the domain specified in design, although this can be altered ...
Abstract Sediment microbial communities from plain river networks exert different effects on pollutant transformation and migration in lake basins. In this study, we examined millions of Illumina reads (16S rRNA gene amplicons) to compare lake, lake wetland, and estuary bacterial communities through ...
An inter-laboratory study was performed to evaluate the performance of a method developed for the quantification of enrofloxacin in chicken meat. Liquid-liquid extraction combined with a clean-up procedure based on solid-phase extraction followed by a liquid chromatography-tandem mass spectrometric ...
Solving the problem of large quantities of organic waste, which represents an enormous ecological and financial burden for all aspects of the process industry, is a necessity. Therefore, there is an emerged need to find specific solutions to utilize raw materials as efficiently as possible in the production ...
As marine ecosystems are influenced by global and regional processes, standardized information on community structure has become crucial for assessing broad-scale responses to natural and anthropogenic disturbances. Extensive biogeographic provinces, such as the Brazilian Province in the southwest Atlantic, ...
Background The whale shark (Rhincodon typus) is known to aggregate in a number of coastal locations globally, however what causes these aggregations to form where they do is largely unknown. This study examines whether bathymetry is an important driver of coastal aggregation locations for R. typus ...
Abstract Coiled tubing (CT) was used on a field on the Norwegian continental shelf to intervene in four separate wells. The campaign objectives were to restore injectivity to two injector wells, prepare a well for plugging and abandonment (P&A), and bring a newly drilled well onto production. The ...
Abstract Oil recovery using Smart Water technology (SWF) can be maximized by optimizing the composition of injected water. Brine optimization is also believed to improve Polymer Flooding (PF) performance. The present study aims to assess and define the potential impact of combining Smart Water with ...
