Image recognition is not very effective in the water environment due to multiple factors, such as high scattering and high scattering in the water column. This is why the relevant parameters in the Faster R-CNN network model need to adjust continuously to improve the effectiveness of water detection. The control variable method adjusts the program's learning rate by tuning the network model's parameters. Then, the number of training rounds is adjusted according to the loss function of each round, and finally, we can get the number of matches with the minimum loss function. Based on the experimental results on the dataset, it is shown that the proposed method not only selects the learning rate with the best detection results but also has the strongest robustness and achieves a 96%-99% recognition rate for passenger ships, cargo ships, warships, and bridges compared with other learning rates. Experiments show that the Faster R-CNN network model detects water targets with significant results, and the best network model learning rate parameter is 6×10-3.
Maritime navigation is an important mode of transportation in the country. With the development of the country and the world, there will inevitably be higher requirements for the safe transportation of ships in the future.

And with the gradual development and improvement of big data and artificial intelligence technology in the industrial field, smart ships are an inevitable trend in the development of the shipbuilding industry. Smart ships need to maintain the stability of the ship to ensure the safety of the ship when operating at sea. Therefore, the research on the autonomous stowage of ballast water for smart ships in the future is very important. This paper analyzes the development background of intelligent ships, introduces the ship optimization model and optimization design algorithm, and speculates the future development direction of intelligent ships.
The progress of science and technology has driven the development of the society, and the application of threedimensional simulation technology in all walks of life has greatly improved people's life. Maritime affairs is an important part of comprehensive transportation. The improvement of maritime supervision and service level is conducive to the construction of domestic first-class economic law enforcement system and international leading maritime management institutions. Now the application of 3D simulation technology to maritime supervision is studied, aiming to improve the quality and efficiency of supervision, make maritime supervision more convenient and have further guarantee. Maritime supervision of ship environment is often more troublesome than personnel management. In the process of monitoring and control, many uncontrollable environmental factors greatly increase the difficulty of supervision, among which the port environment is more complex, which is a difficulty of monitoring and control in maritime supervision. This paper uses MapInfo Professional, Win Topo, Multigen Creator and other operating software to construct the Qingdao port visual simulation environment. The port topographic cloud map of Qingdao Port was captured, and the collected image information was converted into data through MapInfo Professional and Win Topo software, and then modeled by Multigen Creator software. After completing the general terrain outline, the established simulation scene was made more realistic and realistic through some detail processing and optimization means. By describing the establishment of 3D simulation terrain in Qingdao Port, the application status of the simulation technology in ship environment and port management is reflected, which provides a reference for the deeper application of 3D simulation technology in maritime supervision.
In order to optimising the sea traffic network efficiency, improving the safety of shipping and the protection of the environment, it is useful to model the sea network and its spatio-temporal characteristics of the ship patterns. These maritime patterns could also be an a-priori set of knowledge for the upcoming Maritime Autonomous Surface Ships (MASS) which are starting to navigate our seas with or without remote human controls. The above concepts are crucial and essential elements for defining and understanding the Maritime Situational Awareness (MSA). Nowadays the applied methodologies for modelling the maritime traffic use large scale of database for extracting the patterns. The Knowledge Discovery from Data (KDD), strictly connected with Data Mining (DM) is growing significantly to modelling the behaviour of the vessels in relations to their surroundings. This is just one example that confirms the growing up of the cloud computing usage for maritime applications too. Besides these applications there are also a continuous and fast evolution of the IT services, which more often than not means data centre scale-ups with consequent improve of power consumptions. This paper is a case study based on real world data assessing a multi-objective energy consumption analysis. It is based on the comparison between the traditional air conditioning structures known as Heating, Ventilation and Air Conditioning (HVAC) and the Free Cooling Technique (FCT) in order to reduce the data centre power consumption keeping the same number of computational calculations performed.
Underwater heritage is the term commonly used to mean material found underwater. Many states have heightened of underwater heritage remains unprotected. The UNESCO 2001 convention on the protection of the underwater cultural heritage is the foremost international legal reference for the protection or salvage of underwater heritage. To conduct a literature review for this thesis, five keywords were chosen such as UNESCO, under water cultural heritage, marine salvage and sovereignty, exploration, and investigation. The objective is; i) To ensure Malaysia underwater heritage is being well enforced by respective enforcement authorities.; ii) To create an awareness and protection to public and relevant parties.; iii) To identify the relevant implementation of legal enforcement from the respective Malaysia authority) To formulate Malaysia underwater cultural heritage strategic framework for enhancement sustainability development of underwater assets and wealth, and sovereignty. And for the problem statement, i) Lack of proactive measures from operational patrol of underwater cultural heritage for the enforcement from maritime authority,; ii) lack of public disclosure on the importance and existence of underwater heritage in Malaysia by stakeholders,; Iii) Lack of procedures and legal aspects for implementation of underwater cultural heritage in Malaysia water,;iv) None of national underwater cultural heritage strategic framework for sustainability of underwater assets and wealth in Malaysia. Specifically, the component of the underwater heritage is outlined for the protection and conservation of artifacts which have been partially or totally underwater. Qualitative method as main method and data collection from research book, journal article, publish and non-publish report. While expert interviewed via Webex within expert from academician and operational as supportive for this research. Text transcribed has been used for this research and coding system functioned for reference during discussion and findings. This thesis also uses theory of formulation and marine salvage as well as underwater cultural heritage law as a main reference. Finally, underwater cultural heritage strategic framework has been formulated regards to enhancement sustainability development of underwater assets and wealth, and sovereignty. thereby, it shown the Malaysian government commitment and concern to remain national maritime sovereignty.
