Special Issue Information

Dear Colleagues,

Due to a number of advantages over other transportation systems, maritime industries are continuously seeing a surge in fulfilling present sea-borne transportation demands. Naval architects and ship designers are working tirelessly in collaboration with various scientists and engineers to meet the marine transportation demands through the innovation of energy efficient, cost effective but large carrying capacity vessels while keeping the emissions level low. Likewise, offshore engineers are also working hard to maintain the resilience of energy demands ensuring reliable and fully functioning offshore structures. Recent upward trends and aspirations in harvesting marine renewable energies also have contributed to a boost in offshore installations. However, the sustainability of marine sectors is very much reliant on innovations through research and development. We, therefore, encourage you to submit your high-quality research and/or review articles to this special issue.

Regular and irregular waves were numerically generated in a wave canal to investigate hydrodynamic loads acting on a wind turbine monopile and to predict its structural response. The monopile was implemented in the canal and modeled as a flexible structure, with the turbine blades and rotors considered as a point mass situated at the top of the monopile. Fluid–structure interaction (FSI) simulations were performed by coupling a structure solver based on a finite element method (FEM) with an unsteady Reynolds-averaged Navier–Stokes (URANS) equations solver of the finite volume method (FVM). The FSI simulations considered the two-way interaction between the deformable structure and the fluid flow. The URANS equations solver was coupled with the volume of fluid (VoF) method to account for the two-phase flow. In regular waves, numerically predicted total load coefficients occurring at the monopile’s first eigenfrequency compared favorably to experimental measurements. A deviation between calculations and measurements was observed for the total loads in irregular waves. This deviation occurred due to the smaller wave energy density of the numerically predicted irregular wave. Hydroelasticity effects increased wave-induced forces by about 6% and wave induced bending moments by about 16% in regular waves. A relatively strong whipping event was observed, which characterized the hydroelasticity response bending moment of the monopile in irregular long-crested waves. This whipping event also had a significant influence on the loads on the monopile. These investigations demonstrated the favorable use of FSI simulations to predict hydroelasticity effects on a monopile. Full article

The flight deck of an aircraft carrier is subjected to various loads. In addition, the operation of fixed-wing aircraft presents unique structural requirements for the deck. This paper, therefore, compares the structural behaviour of a flight deck which was designed following the guidelines of three classification societies: Lloyd’s Register (LR), Det Norske Veritas Germanischer Lloyd (DNV), and Registro Italiano Navale (RINA). The loading scenarios considered in this work represent the operation of an F-35B Lightning jet from a Queen Elizabeth-class (QEC) aircraft carrier. A commercial finite element analysis (FEA) software ANSYS was also used to investigate the deflection, stress and strain on the deck plates. The analysis identified that only the calculated deck thickness values based on the LR regulations would meet the requirement for the class. This finding was further supported by the FEA.

The ship-breaking industry has become a promising sector in Bangladesh by contributing to the country’s primary steel demand as raw material for re-rolling mills, providing livelihood opportunities for the poor. This paper investigates the livelihood index and health hazards of workers engaged in ship-breaking activities at the Bhatiari coast of Chattogram, Bangladesh. Both qualitative and quantitative data were collected through participatory rural assessment (PRA) tools that included 128 individual interviews (II), ten focus group discussions (FGDs), and 15 key informant interviews (KIIs). The workers’ livelihoods revealed that workers lack basic facilities and are exposed to occupational health hazards due to working in a risky environment. Workers of different origins claimed to have 1 to 6 years of work experience and worked 11 to 12 h a day. More than 60% of workers reported being injured or suffering from various physical problems such as blurred vision, abdominal pain, and skin problems. Labor-intensive and unstable occupations, limited access to medical services, poor housing and sanitation, and lack of basic safety requirements increase workers’ plight. Therefore, the study offers advanced protective equipment, better medical facilities, and a safe workplace to improve the workers’ livelihoods. Full article

Fibre-reinforced polymer (FRP) matrix composites are widely used in large marine structures, and in wind turbines where blade lengths are now over 100 m. Composites are the material of choice for small vessels due to ease of manufacture, high hull girder stiffness, buckling resistance, corrosion resistance and underwater shock resistance. Ships over 100 m are still built using traditional steel and/or aluminium, but so far not FRP. Composite ship lengths have increased over the past 50 years, but fundamental technical challenges remain for the 100 m composite ship. Preliminary studies suggest a possible 30% saving in structural weight, a 7–21% reduction in full load displacement, and a cost saving of 15%. However, economic considerations, design codes, manufacturing limits, safety and end of life scenarios need to be addressed before a 100 m ship is built. Innovative materials and structures, notably carbon fibre composite skinned sandwich construction, or aramid fibres with vinylester modified epoxy resin, should result in increased mechanical performance and consequent improvements in economics and manufacturing processes. A linear extrapolation of length vs. launch dates predicts the first 100 m ship would be launched in 2042. Full article
