Thermoacoustic cooling technology uses high amplitude acoustic standing waves in inert gasses to pump heat It requires no toxic, ozone-depleting, or global warming gasses and has few or no moving Parts, no sliding seals and requires no lubrication for robust and very low maintenance operation. Thermoacoustic cooling units have been demonstrated aboard the Space Shuttle in 1992 and aboard the USS Deyo (DD 989) in 1,995 to cool radar electronics. Currently, a 3-ton electrically driven unit is being built for shipboard application. This 3-ton unit will enable the ship designer to provide greater combat system survivability through distributed system architecture and reduced manning by unit simplicity and resulting high reliability. Additionally, waste heat cooling is an emerging thermoacoustic technology that could utilize stack gas heat from main gas turbine engines or from gas turbines generators to create shipboard cooling. The benefits of this waste heat cooling is lower infrared (IR) signature and reduced fuel consumption.

Environmental sustainability criteria in the multi-oriented shipbuilding industry in Indonesia

引用

Australian Journal of Maritime and Ocean Affairs 2024年第4期16卷 410-430页

作者： Azhar, Ali Harahab, Nuddin Putra, Fadilla Kurniawan, Andi Department of Naval Architecture and Ship Building Faculty of Engineering and Marine Science Hang Tuah University Surabaya Indonesia Postgraduate Environmental Science Doctorate Program Brawijaya University Malang Indonesia

Preliminary studies have highlighted the potential of Indonesia's geographical, suprastructural, and infrastructural conditions to develop a strong shipbuilding industry, which is crucial for the success of the world maritime axis program and sea toll. However, despite high expectations, the industry faces challenges that threaten business sustainability, leading to bankruptcies. To assess business sustainability, it is essential to establish criteria and sub-criteria, which previous studies have overlooked, focusing only on technical and economic factors. Therefore, this research generally aims to develop and analyze environmentally friendly sustainable criteria in the multi-oriented shipyard industry so that it develops in accordance with the vision, mission, goals and strategies. The criteria development process involves identifying and reviewing relevant articles, classifying and refining the criteria, conducting expert validity testing, Pearson Product Moment validity testing, and reliability testing using the Alpha (Cronbach) method. The expert validity testing indicates that ‘people' received the highest average score of 4.67 among the criteria, and ‘infrastructure' scored the highest in the sub-criteria, with a score of 4.75. The validity testing with the Pearson Product Moment method demonstrates that the criteria and sub-criteria are valid and the reliability of 32 sub-criteria indicating their influence on promoting multi-oriented and environmentally sustainable shipbuilding industries. © 2023 Informa UK Limited, trading as Taylor & Francis Group.

Integrated ship recycling industrial estate design concept for Indonesia

引用

IOP Conference Series: Earth and Environmental Science 2022年第1期972卷

作者： Sunaryo Bagus A Tjitrosoemarto Naval Architecture and Marine Engineering Study Program Universitas Indonesia Kampus UI Depok 16424 Indonesia.

Since the implementation of the cabotage principle, the number of Indonesian flagged ships has been increasing significantly, due to the government's incentive on importation tax for used ships. The fleet is dominated by old ships, which most of them will soon be sent for recycling. The ship recycling industry has a great opportunity for the economy of Indonesia, because of its contribution to the steel industry and job creation, but on the other hand it is also a very environmentally unfriendly industry. Currently there is no ship recycling yard complies with the requirements of international and national regulations, most of them are still implementing conventional method, and are not connected to the supporting industries. Based on these issues the study was aimed to design a concept of an integrated green and sustainable ship recycling industry estate, which has all necessary industries and facilities in it, and efficiently connected with each other. Block Plan program was used to optimize the arrangement. It is proposed that five ship recycling yards, large; medium; and smaller capacity, steel mill, waste treatment facility, electricity power plant, fresh water facility, training centre, workers accommodation, hospital, and bus terminal should be included in the estate.

Design of fishing boat for Pelabuhanratu fisherman as one of effort to increase production of capture fisheries. The fishing boat should be proper for the characteristic of its service area, as; capacity of fishing boat up to 60 GT, the fishing boat has minimum 6 fish holds and location of fish hold in the middle body, the fishing boat hull has the bilge keel plate, and the material of hull fishing boat to be made of wooden, steel, aluminium, or fiberglass. Main dimesion of fishing boat is Length Over All = 25.436 m, Breadth = 4.55 m, Draft = 1.6 m, Speed = 12.5 knots. The research had been known every thing that will be supporting the production of capture fisheries like ; amount of fish production = 25.030 ton per day, the fishing port capacity approximately 268.957GT per day, the area of fishing port < 30 hectares, the zone of fish processing industry had not completed, therefore all data research result less than standard of Oceanic Fising Port. So Pelabuhanratu National Fishing Port can not be changed to Oceanic Fishing Port.

The problem of sewage and waste disposal from U. S. Navy ships is recognized by the highest authorities in the Navy. Many activities and individuals are deeply involved in the total problem and its numerous subcategories. The problem of costs of disposal is one of these. This paper discusses four optional methods for the disposal of shipboard domestic wastes. The annualized investment and operating costs associated with the implementation of each of the options are presented. The model considers non-nuclear, sea-going surface ships with a manning level greater than 50 men. Estimates were developed on a per ship per class basis and aggregated for the total surface fleet. This approach permits the inevstigation of different combinations of the options by merely specifying the number and type of ships to be considered in any option. Changes in military effectiveness, which is at least an equally important problem as costing, were not addressed.

作者： Matthew Johnson-Roberson Charles Barto Rounak Mehta Sharath Nittur Sridhar Karl Rosaen Ram Vasudevan Department of Naval Architecture and Marine Engineering University of Michigan Ann Arbor MI USA Electrical Engineering and Computer Science University of Michigan Ann Arbor MI USA Robotics Program University of Michigan Ann Arbor MI USA Mechanical Engineering University of Michigan Ann Arbor MI USA

Deep learning has rapidly transformed the state of the art algorithms used to address a variety of problems in computer vision and robotics. These breakthroughs have relied upon massive amounts of human annotated training data. This time consuming process has begun impeding the progress of these deep learning efforts. This paper describes a method to incorporate photo-realistic computer images from a simulation engine to rapidly generate annotated data that can be used for the training of machine learning algorithms. We demonstrate that a state of the art architecture, which is trained only using these synthetic annotations, performs better than the identical architecture trained on human annotated real-world data, when tested on the KITTI data set for vehicle detection. By training machine learning algorithms on a rich virtual world, real objects in real scenes can be learned and classified using synthetic data. This approach offers the possibility of accelerating deep learning's application to sensor-based classification problems like those that appear in self-driving cars. The source code and data to train and validate the networks described in this paper are made available for researchers.
