“…The result implies that higher temperature causes workers to be exhausted faster. This study support previous studies stating that temperature in the workplace may affect fatigue (Tanabe et al, 2007;Micone & De Waele, 2017). Previous study has reported a difference between workers working below threshold values and above threshold values (Ramdan, 2007).…”

The physical environment of a ship is often found to be below the government’s standard, which affects employees’ health and causes work fatigue. The present study aimed to identify the physical environment and work fatigue in the ship engine room at Manado Port by applying a cross-sectional analytical approach. The study population was forty-one engine room crew of seven ships with Manado-Talaud Archipelago routes with 7-16 hours trip. The research instrument includes a hygrometer, sound level meter, vibration meter, and work fatigue questionnaire (KAUP2). The data were analyzed descriptively and by performing a correlation test. The study found that the ships’ temperature, noise, and vibration exceeded the stipulated threshold limit value. The relationship between the physical environment and work fatigue was also noticed.

“…The fatigue lives of the specimens in the CF tests should depend strongly on the time required to develop a corrosion pit, as corrosion pits are the mechanisms that trigger crack initiation in these tests. The kinetics of corrosion pit formation depend mostly on the loading frequency [ 52 ], the salt concentration [ 53 ], the temperature, and the pH of the corrosive medium [ 54 ]. Since all these variables remained identical for all the specimens, the crack initiation times of the CF tests are believed to have been virtually alike.…”

In this study, the axial fatigue behaviour of hot forging tool steels at room temperature was investigated. Fatigue tests were performed on two steels within the same H13 specification. The fatigue tests were carried out in the high-cycle fatigue domain under normal conditions. These tests were also performed on specimens in contact with a corrosive medium, applying stress values that led to the high-cycle fatigue domain under normal conditions for the sake of comparison. Both materials showed similar fatigue strengths when they were tested under normal conditions. In contrast, corrosion fatigue lives were much lower than in normal tests and differed significantly between the two steels. Crack initiation was triggered by microstructural and surface defects in the normal tests, whereas the formation of corrosion pits caused crack initiation in the corrosion fatigue tests. Moreover, a fracture surface analysis revealed dissimilar crack propagation areas between both steels, which suggested that both steels had different fracture toughness. These results were in line with the differences observed between the carbide and grain sizes of both of the material microstructures.

Sustainable use of the ocean for food and energy production is an emerging area of research in different countries around the world. This goal is pursued by the Australian aquaculture, offshore engineering and renewable energy industries, research organisations and the government through the “Blue Economy Cooperative Research Centre”. To address the challenges of offshore food and energy production, leveraging the benefits of co-location, vertical integration, infrastructure and shared services, will be enabled through the development of novel Multi-Purpose Offshore-Platforms (MPOP). The structural integrity of the designed systems when being deployed in the harsh offshore environment is one of the main challenges in developing the MPOPs. Employing structural reliability analysis methods for assessing the structural safety of the novel aquaculture-MPOPs comes with different limitations. This review aims at shedding light on these limitations and discusses the current status and future directions for structural reliability analysis of a novel aquaculture-MPOP considering Australia’s unique environment. To achieve this aim, challenges which exist at different stages of reliability assessment, from data collection and uncertainty quantification to load and structural modelling and reliability analysis implementation, are discussed. Furthermore, several solutions to these challenges are proposed based on the existing knowledge in other sectors, and particularly from the offshore oil and gas industry. Based on the identified gaps in the review process, potential areas for future research are introduced to enable a safer and more reliable operation of the MPOPs.
