Special Issue Information

Dear Colleagues,

The global maritime transport industry operates according to a set of specific laws. The development of digital systems in the marine industry has resulted in the appearance of significant indicators. Today, the ship’s crew is decreasing, the ship’s productivity is increasing, and environmental indicators are being monitored. The development of the industry requires research in various fields of engineering, such as robotics, automation, neural networks, and ecology, amongst others. This research will significantly contribute to the development of the industry as a whole.

This Special Issue provides a platform for academics, scientists, and industry professionals to exchange the most contemporary ideas, techniques, methods, and experiences in the area of ship energy systems, including modelling, optimisation, control, maintenance, safety, autonomy, environmental friendliness, regulatory framework, and sustainability.

Ship ballast pumps have stringent requirements for their transient characteristics. Here, the pneumatic control valve and programmable logic controller (PLC) are applied to realize the rapid reduction in flow rate for ballast pumps, and the dynamic pressure of steady and transient conditions and inner flow for the ballast pump are tested and analyzed. The results show that the dynamic pressure of each study scheme has cyclical increasing trends, however, the larger the amplitude of the flow rate reduction is, the greater the pressure increasing rate of the two measuring points. While the flow rate decreases to 0.4× Qd and 0.2× Qd, the rate of pressure increase is first fast and then slow. The dynamic pressure pulsation intensity is higher than the corresponding steady-state conditions after the transient conditions. With the increase in flow rate reduction, the characteristic frequencies of the dynamic pressure are 1APF (axial passing frequency) and 1BPF (blade passing frequency) and their harmonic frequency. The rapid decrease in flow rate causes the separation vortex in the impeller channel to be generated in advance, and the scale increases, which reduces the pulsation intensity of the pump outlet to prevent an increase in the level of broadband pulsation between 2APF and 1BPF.

Developing countries, despite being the major suppliers of maritime manpower, lag in their future-proof competence development. This study explores whether the current maritime education and training (MET) practices for marine engineering education in a developing nation are perceived as sufficient by the early-stage marine engineers. The current competence requirements set by the Standards of Training, Certification and Watchkeeping for Seafarers (STCW’74 as amended) are compared and contrasted against the current MET practices as well as the future needs for remotely controlled autonomous ship operations. Bangladesh, a maritime nation in the Southeast Asia region was selected as a developing nation for this study. An online survey was conducted among early-stage professional marine engineers. The analysis of 62 valid responses revealed that current MET practices are significantly perceived to be satisfactory for acquiring non-technical competencies, such as being proficient in the English language, but are less satisfactory for instilling technical competencies such as of electrical and electronics, knowledge regarding seaworthiness of ships, as well as medical first aid. In addition, the findings highlight the perceived gaps in existing marine engineering education as well as the need for future studies focused on re-training the future maritime workforce that could potentially improve MET strategies and practices in the developing nations.

Since fuel prices account for approximately 40% of a ship’s operating costs, shipping companies worldwide have made significant efforts to save energy on board such as introducing new technologies or machine operation methods. Many ship operators have adopted an advanced control system using a variable-speed pump and/or an optimizing control system of a three-way valve on the outlet side of the central cooling system. It is often considered that the best way to control a central cooling system is to integrate the two control systems. However, when applied in practice, there is a frequent uncontrollable phenomenon in which the three-way valve is opened to its minimum and the variable-speed seawater pump is operated at its maximum, resulting in a large amount of energy consumption. Therefore, in this study, the speed of the variable-speed seawater pump is set to the minimum, and the feed-forward controller is adopted for the three-way valve control system. The input variable of the feed-forward controller is the Main Engine load, and it is designed to directly control the bypass openness with the three-way valve controller. Using this design, it was demonstrated that the variable-speed seawater pump was operated at a minimum and energy was saved. Full article

The article examines the synthesis of algorithms for the estimation of the random parameters of ship movement models, based on measured information in field tests. In addition, accuracy analysis of the synthesized algorithms is provided. The derived algorithms are relatively simple and allow highly precise unknown parameters for estimation of ship motion models at the non-real-time scale to be obtained using the measurements recorded in field tests. The results can be used in the construction of automated ship control systems, or in the development of navigation simulators and the creation of ship models. Full article

In the article, the mechanical and electromechanical starting characteristics of an asynchronous electric drive of a two-piston ship compressor are investigated by a numerical method. A distinctive feature of the operation of the electric drive of a reciprocating compressor is that its load torque changes with a certain frequency. The dependence of the load torque on the shaft of the electric drive of the piston compressor on the angle of rotation is presented in the form of a Fourier series. Moments of inertia are reduced to a single system that performs a rotary motion. Mechanical and electromechanical starting characteristics are constructed. The estimation of the degree of torque pulsations on the shaft is made. It is determined that the compressor has a large amplitude of torque ripple on the shaft, which, in turn, affects the magnitude of the current ripple in the electric drive. Full article

The reasonable decision of ship detention plays a vital role in flag state control (FSC). Machine learning algorithms can be applied as aid tools for identifying ship detention. In this study, we propose a novel interpretable ship detention decision-making model based on machine learning, termed SMOTE-XGBoost-Ship detention model (SMO-XGB-SD), using the extreme gradient boosting (XGBoost) algorithm and the synthetic minority oversampling technique (SMOTE) algorithm to identify whether a ship should be detained. Our verification results show that the SMO-XGB-SD algorithm outperforms random forest (RF), support vector machine (SVM), and logistic regression (LR) algorithm. In addition, the new algorithm also provides a reasonable interpretation of model performance and highlights the most important features for identifying ship detention using the Shapley additive explanations (SHAP) algorithm. The SMO-XGB-SD model provides an effective basis for aiding decisions on ship detention by inland flag state control officers (FSCOs) and the ship safety management of ship operating companies, as well as training services for new FSCOs in maritime organizations.

If a ship’s hull or tank breaks, the ship may sink, or oil spills can cause enormous damage to the environment. If the ship is equipped with a capable, cost-effective oil or liquid flow stop emergency device, casualties and marine pollution could be reduced. Many magnetic-type liquid spill stop emergency devices developed since 1904 have limitations, such as difficulties with installation and impossibility of use during sailing. This study demonstrated the applicability of a magnetic-type liquid spill stop emergency device through tests for water pressure and leakage, attachment, magnetic fields, and the generation of sparks. Results showed that the device can be applied to the ship’s side hull and bottom with a specified minimum diameter at a pressure depth of 1.0 kg/cm2 while sailing at a speed of 18 kts (9.26 m/s). If the distance from the device was at least approximately 750 mm, the magnetic field had no effect, and there was no risk of explosion due to sparks. A cost–benefit analysis based on the International Maritime Organization-approved guidelines for formal safety assessment confirmed the cost effectiveness of the device. This experimental study confirmed that the magnetic liquid stop emergency device is generally applicable to a ship’s hull. Full article
