The propeller is a typical high skewed propeller (HSP) of the training ship ‘Seiun-Maru’, whose experimental data have been frequently used by many researchers. The viscous flow is solved by an incompressible Reynolds Averaged Navier–Stokes (RANS) method using Ansys-CFX solver. The shear stress transport (SST) k–ω turbulence model is employed for the simulation of the propeller in a fully turbulent flow. The thrust and torque coefficients at 10 presented advance coefficients (between 0.1 and 1) showed good agreement comparing with experimental data. The numerical results are increased in the wake flows. The unsteady oscillating load of thrust and torque is presented and discussed for one blade and whole blades during one cycle at different cross-flow wakes and at advance coefficient (J = 0.85). Based on the numerical results, when the cross-flow wake is increased by 20% and 50%, the thrust at J = 0.85 are increased about 2.03% and 4.71% respectively and the torque at J = 0.85 is increased about 1.04% and 2.69%, respectively. Moreover, pressure distribution and streamlines are also presented and discussed.","PeriodicalId":50152,"journal":{"name":"Journal of Marine Engineering and Technology","volume":"21 1","pages":"271 - 280"},"PeriodicalIF":2.6,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20464177.2021.1893136","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46727569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The performance of the propeller is subjected to significant alteration, as it experiences flow, coming at an angle. For this purpose, numerical simulation is performed for the INSEAN Propeller E779A. Turbulence model based on the two-equation Reynolds Averaged Navier Stokes (RANS) turbulence model, i.e. k–ω SST (Shear Stress Transport) method is implied to assess hydrodynamic performance, while hydro-acoustic assessment in near field is calculated by coupling RANS with the Ffowcs Williams Hawking (FW-H) equation. Validation is performed by comparing the numerically computed results from the current study with the available experimental data in straight flow conditions and then the off-design conditions are modelled by using the combinations of three advance ratios with four different flow angles. As a result, distinct differences among the hydrodynamic and hydro-acoustic features are analysed. The hydrodynamic coefficients are compared, and their change is analysed in detail. For the hydro-acoustic analysis, sound pressure level, attenuation frequency and directivity analysis are conducted and based on these factors the effect of the off-design condition on the aquatic life is discussed, thus showing the strong influence of the off-design condition on the hydro-acoustics of the underwater water propeller.","PeriodicalId":50152,"journal":{"name":"Journal of Marine Engineering and Technology","volume":"21 1","pages":"224 - 233"},"PeriodicalIF":2.6,"publicationDate":"2020-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20464177.2020.1865250","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43466207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ADC12 alloy composite with titanium carbide and zircon sand samples were also prepared for comparison of dual reinforcement particles on microstructural features and wear behaviour in various slurry concentrations. Titanium carbide (44–60 µm) and zircon sand (20–33 µm) particles are reinforced in the alloy by the two-step stir-casting method. Slurry erosion wear study reveals that the dual particle reinforcement enhances the wear resistance as compared to single-particle reinforcement if mixed in a definite proportion.

Owing to its mature technology process and low production cost, silicon piezoresistive sensor is widely applied in the field of industrial pressure measurement. However, its temperature effect can result in non-negligible dynamic error, which cannot meet requirement of deep sea environment. The silicon-on-sapphire pressure sensor based on stress cup structure is presented. The output voltage values show a high deviation in the range of −6∼50°C due to temperature drift. In order to minimise this temperature effect, a temperature compensation algorithm is proposed to realise 0.03% accuracy in the full scale 60 MPa range. Compared with a reference commercial sensor in deep sea experiment, the test pressure sensors exhibit minor error, excellent similarity and coherence. This numerical method provides a new research direction for environmental self-adaptive sensor. It can be emphasised that this sensor will have a good application prospect in unattended long-term ocean observation system.","PeriodicalId":50152,"journal":{"name":"Journal of Marine Engineering and Technology","volume":"19 1","pages":"207 - 214"},"PeriodicalIF":2.6,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20464177.2019.1633881","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42382405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vessels that transit the Canal should normally save distance, time and operating cost. During the current economic recession and low fuel prices, longer shipping routes may be chosen to avoid the Canal transit fees. Harsh weather conditions may be encountered along these lengthy routes resulting in higher stresses and structural fatigue damage on ship’s hull, which would impact structural safety and affects the cost of ship maintenance. This paper quantifies ship structural fatigue damage along the routes: Suez Canal transit versus the Cape of Good Hope. Several voyages of an Aframax tanker along these routes are selected and evaluated for fatigue damage using a route-specific spectral fatigue damage assessment approach. Fatigue accumulation during the tanker lifetime, for each trade route, is computed as the sum of all the encountered sea states having caused fatigue damage along that route. Results are presented as fatigue damage and fatigue life for each trade route. Results show that in addition to saving in distance and time, less accumulated fatigue is achieved along the Suez Canal route.","PeriodicalId":50152,"journal":{"name":"Journal of Marine Engineering and Technology","volume":"19 1","pages":"257 - 265"},"PeriodicalIF":2.6,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20464177.2019.1572703","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47506267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is always important to monitor the health status of marine turbine generators. The lubricant oil usually carries abundant information on the turbine operation conditions. Various oil parameters of the turbines have been used in the existing monitoring systems. However, many of them conflict with each other by contrary detection results. Hence, it should eliminate the redundant oil parameters for efficient condition monitoring. Although many research studies addressed the redundant feature reduction issue using principal component analysis (PCA), PCA is designed for features with a linear relationship, which is not the case in marine turbine generator monitoring. This paper proposes a new nonlinear analysis method, the improved control-limit based PCA, to extract distinct failure indicators from the oil parameters of marine turbine generators. The contribution of this method is that the Hotelling statistic and Q statistic are combined to calculate a fixed control limit for PCA. The ability of the improved PCA to dealing with nonlinearity has been significantly enhanced by the proposed method. Experimental validation demonstrates that the extracted failure indicator using the proposed method is more effective than existing monitoring indexes with respect to fault detection accuracy.","PeriodicalId":50152,"journal":{"name":"Journal of Marine Engineering and Technology","volume":"19 1","pages":"249 - 256"},"PeriodicalIF":2.6,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20464177.2019.1655135","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48738221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since ports face various safety issues in design, installation, operation and maintenance processes, there are many aspects open for improvement in Occupational Health and Safety risk assessment and it is required to deal with risks, reduce them to an acceptable level and control. To struggle with emerging risks and manage this process better, a risk assessment framework is proposed for ports in this study. A case study is performed in a Turkish international port authority using the proposed framework. Fuzzy Analytic Hierarchy Process (FAHP), which is a commonly used fuzzy multi-criteria decision-making method, was used in weighting two risk factors: likelihood and severity. The orders of priority of hazards were then determined by a fuzzy-based VIKOR method based on the output of FAHP. The proposed framework overcomes some drawbacks, including a lack of assignment on the weight to two risk assessment factors and lack of the high dependence of the prioritisation on the experts’ opinions. To validate the results, a sensitivity analysis was conducted. In conclusion, the study contributes to the applicability of the proposed framework to assess the risks in ports and provides a distinct risk prioritisation.","PeriodicalId":50152,"journal":{"name":"Journal of Marine Engineering and Technology","volume":"19 1","pages":"161 - 175"},"PeriodicalIF":2.6,"publicationDate":"2020-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20464177.2019.1670994","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42272037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
