Penerapan Terhadap Kepatuhan Konvensi Ballast Water Management Dari Awak Kapal Niaga Di Indonesia

The International Maritime Organization (IMO) through the Environmental Protection Committee (MEPC/Marine Environment Protection Committee) since 2004 has established the international Convention on the Control and Management of Ship's Ballast Water and Sediments (BWM 2004), which seeks to protect marine waters from the impact of water discharge. commercial ship ballast The aim of this research is to determine the extent of implementation of the 2004 BWM Convention in Indonesia through questionnaires and interviews given to seafarer respondents in Indonesia. The compliance of commercial ship crews with PTES shows that the ship crews have not implemented the Ballast Water Management Convention, namely exchanging ship ballast water at sea according to standard D 1. The results of a questionnaire conducted on Indonesian merchant ship crews consisting of student crew members and student officers show that water exchange Ballast in the middle of the sea by merchant ships is only worth 14.5%. Commercial ships that have documents related to Ballast Water Management are also obtained below the 24% figure. PTES managers should manage ballast water at ports as the cheapest and most efficient solution compared to managing ballast water by commercial ships.

Discussion on the Frequent Burning and Erosion of Marine Medium-Speed Diesel Engine Valves: A Case Study of MAR 8N330 Diesel Engine

In the practice of ship management, valve burning and erosion is a common and adversely affecting incident, which can lead to a series of serious consequences. This article analyzes the frequent burning and erosion of medium-speed diesel engine valves from seven aspects: the harsh working conditions of the valves, the impact of environmental temperature, the impact of cylinder sealing status, the corrosion of valves by low-quality fuel oil, the influence of the intake and exhaust system, the impact of high or too low load operation, and the influence of valve clearance and sealing surfaces. Corresponding prevention and control measures are proposed. This provides beneficial ideas and reference for decision-making for engine room personnel to smoothly handle valve burning and erosion faults and ensure the safe navigation of ships.

Bloom forming species transported by ballast water under the management of D-1 and D-2 standards—Implications for current ballast water regulations

Ballast water (BW) is a well-known transporter for introducing non-indigenous aquatic organisms. To reduce such risks associated with BW discharge, the International Maritime Organization (IMO) adopted the International Convention for the Control and Management of Ships' Ballast Water and Sediments (BWM Convention). We examined the abundance and diversity of bloom forming species in BW under the management of Regulation D-1 Ballast Water Exchange Standard and D-2 Ballast Water Performance Standard. The abundance and richness of bloom forming species were also examined in relation to ballast water age. Our findings indicate the abundance and diversity of bloom forming species were significantly lower in BW under the management of D-2 standard than that under D-1 standard. The abundance and richness represent no statistically significant correlation with BW age (p = 0.76 and p = 0.43, respectively). Some resistant species persist in ballast water. Thereby, we further provide some advice to overcome the existing challenges for the implementation of the Regulation D-2.

Analysis of the existing regulations on certification and training of autonomous vessels operators

The development of autonomous navigation has reached a stage where the issue of creating a system for training specialists in the field of autonomous ship management and developing a regulatory framework that defines the requirements for methodological, personnel and logistical support for such training arises. A brief analysis of the available bibliographic sources on the topic of training operators of autonomous vessels is presented. The requirements of the procedures for the training and certification of autonomous ships operators contained in three regulatory documents published to date such as Maritime Autonomous Surface Ships. Principles and Code of Practice of the British Marine Industry Association, Regulations for the Classification of Offshore Autonomous and Remotely Operated Surface Vessels of the Russian Maritime Register of Shipping and Norwegian Register Standard are considered. A list of basic competencies necessary for the management of autonomous vessels has been formed. A significant part of the knowledge, skills and abilities that make up these competencies are acquired at the stage of training under programs for obtaining a professional seafarer diploma at the management level. The competencies of the autonomous vessel operator are formed on the basis of maritime competencies by adding additional knowledge, skills and abilities that reflect the specifics of the serviced autonomous vessels, equipment and apparatus used in a particular remote control center and navigation conditions in the serviced area. Additional competencies of the operator are largely related to other specialties (IT specialists, electromechanics, radio specialists). In the future, within the framework of the international regulation carried out by the IMO, in the training of autonomous ships operators, the approach underlying the training of ship traffic control systems operators can be used.

Sustainable shipping management: Definitions, critical success factors, drivers and performance

Sustainable shipping management (SSM) is one of the greatest challenges in the 21st century which attracts much attention and interest from global regulatory bodies, industry players, and academics. The objective of this study is to review and consolidate the topic of SSM, specifically, the definitions, critical success factors (CSFs), drivers, and their effects on organizational performance. A systematic review of academic journals is conducted. The review suggests that (1) there are seven CSFs of SSM, namely, government support, organizational commitment, strategic alignment, relationship management, knowledge management, technology acceptance, and performance measurement; (2) shipping firms are motivated to adopt SSM due to institutional pressure and the desire to enhance organizational performance; (3) SSM can lead to better financial and non-financial performances but the relationships are contingent on external and internal conditions. External conditions consist of the stakeholder influence capacity and shippers' belief whereas internal conditions involve the firms’ competitive strategy, continuous improvement capability, green capability, innovation capability, pace, and consistency. This study contributes to the literature by consolidating the scattered research on SSM, providing greater theoretical insight into the CSFs of SSM, the drivers of SSM, the impact SSM has on performances and implications to academia, government and policymakers, and strategic team of shipping companies to manage sustainability in the maritime transport industry.

Determinants of Ship Management Revenues: The Case of Cyprus

We explore, for the first time in the literature, how the revenues of ship management companies respond to macroeconomic exogenous shocks. Using data for ship-management companies in Cyprus, we find evidence that a demand shock has the largest impact on revenues, exhibiting an almost one-for-one relationship. If the demand shock is permanent, we observe a ceteris paribus permanent effect on revenues. Similarly, this occurs irrespective of the final effect that demand has on the relevant freight rate, proxied via the Baltic dry and tanker (dirty and clean) indices. The BDI and the BDTI indices have a smaller effect on revenues, standing at approximately 0.05% for every 1% shock, while the clean tanker index does not have an effect, most likely due to their fleet composition. In accordance with the literature, we find that a shock in the price of Brent oil increases revenues. Our results bear importance not only for ship management companies per se, but also for countries that are ship management hubs.

The finest diamond must be green: a closer look at the roles of institution in shipping firms' sustainable practices.

Shipping companies' implementation of sustainable shipping management is an important means of protecting major water bodies in the marine environment. This research establishes a theoretical model based on institutional theory and incorporates a micro-consciousness level to explore the factors influencing companies' implementation of sustainable shipping practices. After surveying the management of Chinese shipping companies, a total of 282 datasets were obtained for analysis. This study demonstrated that rules and regulations, societal norms, environmental awareness, and legal awareness can improve shipping companies' sustainable shipping practices. Meanwhile, these practices have a positive impact on the environmental, financial, and competitive performance of shipping companies. Moreover, these findings are highly significant for maritime environmental protection and sustainability.

Roles and challenges of seafarers for implementation of energy efficiency operational measures onboard ships

As international shipping contributes to 2.89% of global carbon dioxide (CO2) emissions, the International Maritime Organization (IMO) has set a target of reducing the carbon intensity by at least 40% by 2030 and 70% by 2050 compared to 2008. To achieve these goals, the IMO has developed guidelines and regulations for enhancing energy efficiency in ship design and operation, such as adopting various operational measures, low-carbon fuels, innovative technologies, and retrofits. A purposive sampling strategy was employed in this study to ensure a representative sample, engaging seafarers, ship managers, and technical and operations managers from 46 shipping companies worldwide. The study demonstrates that seafarers actively engage in various energy efficiency practices, with navigation, cargo works, deck operations, and port-related measures divided between the master and deck crews. Chief engineers and engine crews are involved in power generation, propulsion engines, and engine load management. Onshore technical managers oversee both groups to ensure the successful implementation of the Ship Energy Efficiency Management Plan (SEEMP). However, seafarers encounter challenges such as increased workload, additional paperwork, heightened inspections by regulatory bodies, enhanced planned maintenance, and increased technical difficulties in executing SEEMP onboard ships. Furthermore, the implementation of SEEMP has also affected the traditional work culture of crewmembers, who rarely receive recognition or incentives for their efforts. As part of its recommendations, the study emphasizes the need for improved working conditions, training, and incentives, as well as introducing new technologies to reduce workloads and ensure compliance with SEEMP.

Fatigue at sea during and after the COVID-19 pandemic: A comparative study of two matched samples of seafarers

This paper examines seafarers’ experience of fatigue during and after the pandemic. A multi-phase mixed methods research design was used, including two quantitative surveys (Nduring-pandemic=501 and Nafter-pandemic=412) and 36 in-depth interviews. Applying propensity score matching the two samples to approximate the conditions of a randomized controlled experiment, the study shows that surprisingly seafarers reported higher levels of fatigue after the pandemic. Qualitative interviews with seafarers and ship managers reveal the underlying reason – the intensified ship inspection regime together with policy and regulatory updates/revisions in the immediate aftermath of the pandemic increased seafarers’ workload and made seafarers more fatigued. The results of the two surveys also show that while fatigue risk factors differed between the two periods, fatigue risk can be managed and mitigated in both periods by implementing fatigue risk management policies and practices. Policy and management implications for improving seafarers’ occupational health and safety are discussed at the end of the paper.

A Marine Small-Targets Classification Algorithm Based on Improved Convolutional Neural Networks

Deep learning, especially convolutional neural network (CNN) techniques, has been shown to have superior performance in ship classification, as have small-target recognition studies in safety inspections of hydraulic structures such as ports and dams. High-resolution synthetic aperture radar (SAR)-based maritime ship classification plays an increasingly important role in marine surveillance, marine rescue, and maritime ship management. To improve ship classification accuracy and training efficiency, we proposed a CNN-based ship classification method. Firstly, the image characteristics of different ship structures and the materials of ship SAR images were analyzed. We then constructed a ship SAR image dataset and performed preprocessing operations such as averaging. Combined with a classic neural network structure, we created a new convolutional module, namely, the Inception-Residual Controller (IRC) module. A convolutional neural network was built based on the IRC module to extract image features and establish a ship classification model. Finally, we conducted simulation experiments for ship classification and analyzed the experimental results for comparison. The experimental results showed that the average accuracy of ship classification of the model in this paper reached 98.71%, which was approximately 3% more accurate than the traditional network model and approximately 1% more accurate compared with other recently improved models. The new module also performed well in evaluation metrics, such as the recall rate, with accurate classifications. The model could satisfactorily describe different ship types. Therefore, it could be applied to marine ship classification management with the possibility of being extended to hydraulic building target recognition tasks.

A New Method of Ship Type Identification Based on Underwater Radiated Noise Signals

Ship type identification is an important basis for ship management and monitoring. The paper proposed a new method of ship type identification by combining characteristic parameters from the energy difference between high and low frequencies and the sensitive IMF variance mean value based on the modal decomposition of the underwater radiated noise signals using the Ensemble Empirical Mode Decomposition (EEMD) method. The comparison shows that the characteristic parameters of different types of ship, underwater radiated noises are different, whereas those of the same types of ship, underwater radiated noises fall in close range. Validation experiments based on randomly selected ship underwater radiated noise samples manifest that the method is of good separability for the four types of ship underwater radiated noises in the Deepship dataset. It has a higher identification rate than other methods within the distance range of ship underwater radiated noise detection in the dataset. The accuracy of this method tends to decrease with distance in the classification experiments of the ship underwater radiated noises at different distances.

Thrust distribution algorithm based on supervision and switching and swarm intelligence

The ship power positioning control system is the key to maintain the normal operation of the ship, and it is also the basic premise and foundation for the accurate positioning and stable forward movement of the ship, so many ship management and production enterprises attach great importance to the design and construction of the ship power positioning control system. "Thrust distribution" has always been the key technology for designing and constructing ship power positioning control system. When constructing ship power positioning control system by using thrust distribution technology, it is not only necessary to consider the constraint optimization of thrust limit and thrust rate of change limit of propeller, but also the constraint optimization of azimuth rate of change limit, mechanical wear optimization, restricted area limit optimization, etc. It is also necessary to consider the constraint optimization of azimuth rate of change limit, mechanical wear and tear, restricted area limit, etc. The thrust distribution algorithm based on supervision and switching and group intelligence can comprehensively deal with these constraints, which can improve the functions of the ship power positioning control system and solve the convergence problem in the system operation, and improve the operation efficiency, safety and stability of the ship power positioning control system. In this paper, the author discusses the thrust distribution algorithm based on supervision and switching and group intelligence in depth, combining relevant literature and the actual problem of thrust distribution.
