A recovery system for an automatic spraying robot to conduct the spraying operation outdoors for ships is designed in this paper, which addresses the pollution problem of volatile organic compounds (VOCs) by employing the vacuum recovery method. The recovery system consists of the recovery hood, nozzle, and vacuum tubes. The recovery hood is the critical part of the recovery system and is designed with internal and external cavities, as well as four vacuum tubes for recycling VOCs. Based on the computational fluid dynamics (CFD) method, simulation in the time domain of the gas–liquid interaction, droplet evaporation, and wall impingement is conducted. To identify the better recovery performance, three vacuum recovery-hood schemes are designed, and their performance is compared. The numerical results show that the distance between the vacuum tubes and the intake gap has a significant impact on the VOCs’ recovery effect. One of the main reasons for the escape of VOCs is that the swirling airflows in the baffle plane act as vortices which may capture VOCs, causing the accumulation of VOCs beyond the capacity of the external cavity. Dividing the external cavity into four chambers with deflectors (with each chamber equipped with one vacuum tube only) can significantly reduce the leakage rate of the recovery system. The recovery system provides a theoretical solution for implementing the prevention and control of VOCs in shipyards as soon as possible.

“…Although these technologies are being implemented to increase the efficiency of the resources, to ensure the management of complex systems, and to increase the sustained success [39], their potential to improve safety and security and to protect the environment cannot be unexploited. In this regard, a series of promising specific technologies related to the shipbuilding digital transformation have already been proposed, such as augmented reality [40], virtual reality [41], computer vision [42], digital twins [43], IoT [44], real time wireless location systems [45], autonomous vehicles [46] and robotic arms [47], among many others. However, to the best of our knowledge, there is a lack of a comprehensive and integrated overview of these technologies to provide a comparative measure between current operational processes and those enabled by these ones.…”

A large vessel, such as a container ship or an oil tanker, requires painting processes that include not only application, but also cleaning, substrate preparation and corrosion treatment. Moreover, these processes take place during construction (both in the construction of blocks in the workshop and in the assembly at the dock) and also during the operation phase of its life cycle, as part of its maintenance. This research analyzes the advantages of the implementation of key enabling technologies in painting processes versus the proposal of preventive measures, collective and individual protection, and training of workers in traditional manual processes. Using the Fine-Kinney method, which assesses potential hazards and associated risks, the degree of danger of the different tasks present in the current painting processes of large vessels is measured. These risk scores is compared with those of the new activities resulting from the simulation and automation of the associated processes, analyzing their justification by confronting their level of correctness (risk mitigation) with the cost factors of their implementation. The results show that, from a health and safety point of view, the proposal of these measures is fully justified. Therefore, it can be concluded that the inclusion of key enabling technologies in the painting processes of a ship throughout its life cycle drastically reduces risk levels, improving the safety and health conditions of the workers involved, without prejudice to an increase in the cost of services or in the delivery deadlines to the client, which confirms their reliability.

“…For ships immersed in seawater for a long time, the corrosion is more serious. In general, ship rust removal and cleaning are preliminary steps to paint [3,4]. After rust removal, spray painting can be carried out to protect a ship's walls from corrosion to extend the service life of the ship.…”

With the advancement in science and technology, a wall-climbing robot attached to the ship's outer surface is increasingly replacing humans in the rust removal. The magnetic force is not just the adsorption force but also the moving resistance force, which is currently the technological bottleneck in wall-climbing robotics based on magnetic adsorption. This paper proposes a novel wall-climbing robot based on electrically controlled permanent magnet technology to solve this problem. An electrically controlled permanent magnetic wall-climbing robot is proposed to realize the function of magnetization and demagnetization by changing the pulse current. The results of the experiments reveal that the magnetizing force is adequately adsorbed on the ship's outer surface. The magnetic attraction force is close to 0 N during demagnetization, meaning that the system is fully unloaded, as predicted by the theoretical analysis.
