“…In 2021, Ha et al [84] investigated the characteristics of slamming loads on the bow of an FPSO in the ocean wave basin of the Korea Research Institute of Ships and Ocean Engineering (KRISO). In this experiment, a slamming impact load was generated with three heading angles (180 • , 165 • , and 150 • ) and measured using 15 force sensors attached to the bow.…”

The development of human civilization over the last decade has reached a landmark as Industry 4.0 has been widely introduced. Several aspects of industry and manufacturing activities are changing due to the Internet of Things (IoT), location detection technologies, and advanced human–machine interfaces. To enact industrial affairs under those specifications, a sensor is required to transform physical events into numerical information. The use of sensors in marine applications also appears in research and studies, in which the sensor is used for both monitoring the phenomena of a designated subject and data acquisition. Achievements in quantifying complex phenomena in critical maritime designs are fascinating subjects to discuss regarding their development and current states, which may be reliable references for further research on developing sensors and related measurement analysis tools in marine, shipbuilding, and shipping fields. This comprehensive review covers several discussion topics, including the origins and development of sensor technology, applied sensor engineering in logistic and shipping activities, the hydrodynamic characterization of designed hulls, the monitoring of advanced machinery performance, Arctic-based field observations, the detection of vibration-based damage to offshore structures, corrosion control and monitoring, and the measurement of explosions on critical maritime infrastructures.

“…Moreover, due to the large length-to-width ratio of ship-type FPSOs, their slamming exhibits strong directionality, significantly influenced by the direction of the waves. Ha et al [18] used experimental methods to discuss the slamming effect of breaking waves on ship-type FPSOs and discovered that the wave angle influenced the location of the maximum slamming pressure. Guilherme et al [19] adopted experimental and numerical methods to study wave slamming on the upper deck of ship-type FPSOs under different regular waves during Beam sea conditions.…”

For the new sandglass-type FPSO, the unique shape of its floating body with oblique side and external expansion can significantly improve the motion performance, but meanwhile may result in specific slamming characteristics in waves. On this basis, this paper establishes a CFD method including numerical wave-tank technique based on the Open FOAM platform. Therein, the velocity-inlet boundary method and the active absorption method are applied for numerical wave-making and wave-absorption. Compared with experimental results, the numerical method can be validated to be accurate enough to simulate wave slamming on floating ocean platforms. Then, the specific slamming phenomena on the sandglass-type floating body under a classic long wave can be investigated by comparing with the cylindrical model, including nonlinear wave rollover and breaking, water cushion, rooster-tail wave, side wave, water tongue, and so on. The mechanism of these phenomena and their effects on slamming pressure are studied. The essences of typical peaks in the time-history curve of the slamming pressure are mainly discussed. More interestingly, the main peak can be found to be related to the small peak due the amount of the broken water and the thickness of the water cushion. Finally, the slamming characteristics of the sandglass-type model in a classic short-wave condition are comparatively discussed.

“…Xie et al (2020) applied a CFD method to simulate the water entry problem with obvious air effect and they discussed the influence of bulbous bow on the hydrodynamic characteristics during water impacts. Ha et al (2021) studied two types of slamming impact loads and they found that the velocities of the sway and roll motions to be significant determinants of the slamming impact load under the oblique wave conditions. Niklas and Pruszko (2019) presented a CFD seakeeping analysis for a case study vessel in two variants: V-shaped bulbous bow hull form (as built) and innovative hull form (X-bow type), they obtained the influence of redesigning the ship on selected seakeeping aspects.…”
