“…The Internet of Vessels integrated communication and control platform, between Internet of Vessels as the basis, realises the operation of ships and the unified reception of information, and then uses the established integrated ship network to realise resource sharing, using decentralised data system management technology to decentralise physical locations using computer networks, but management control is to concentrate on multiple logical units connected at different degrees, and then data information integration through middleware. The logical architecture of the entire integrated communication and control platform for the Internet of Vessels can be divided into four parts: data collection, data integration, data sharing and data analysis [9] .Data integration: Distributed data integration technology is used to integrate and consolidate the fragmented data on the ship through middleware and then store it in unison between the collected information.…”

The paper focuses on the integrated analysis of the communication control platform and proposes the integration of communication information and its processing through middleware, so that users can find the desired information more accurately and improve the efficiency of maritime communication. The integrated communication and control platform for ship networking makes use of VTS (Vessel Traffic Management System) and AIS (Automatic Identification System) information fusion technology, related network technology, information processing technology, data management technology, etc., to realise the integration of communication automation betweenin the ship and between the ship and the outside world, solving the problems of scattered and confused ship communication information, thus realising efficient data communication and resource sharing, which makes the various systems on the ship highly integrated and integrated, and solves the problem of long communication time and short communication distance.

As one of the world's largest archipelagic nations, Indonesia is tasked with the crucial responsibility of supervising and protecting its territorial waters from threats such as illegal fishing and damage to coral reefs. The effective and efficient execution of this task relies heavily on the use of fast patrol boats. Consequently, the need to investigate the hydrodynamic characteristics of these boats' hulls is paramount. This study is primarily focused on the analysis and design of fast patrol boat hull prototypes. Our objective is to ascertain a practical design methodology that yields the optimal shape and size of the boat's hull. The adopted research methodology involved the design and analysis of eleven hull prototypes, evaluated based on resistance, stability, and seakeeping criteria. Five models were adapted from the reference ship, with a deadweight tonnage (DWT) variation of 2-3.5 tons. Three models employed the regression method with a block coefficient (CB) variation of 0.45-0.46, while the remaining three models utilized the scaling method, derived from the reference ship with the lowest resistance. The models in both the regression and scaling methods applied the primary size derived from the linear regression results of the five reference vessels. From the analysis, it was found that models developed using the regression method demonstrated superior hydrodynamic characteristics, denoted by consistently higher total values. This research provides valuable insights for the development of efficient fast patrol boats, which is crucial for the effective management of Indonesia's expansive maritime territory.

“…The rapid growth in harbor traffic has led to marine traffic accidents occurring frequently. Ships detection and classification is of great practical value to marine surveillance in the harbor environment [ 1 , 2 ]. According to the imaging types for ships, there are mainly synthetic aperture radar images (SAR), spaceborne optical images (SOI), and visible images.…”

The efficiency and accuracy of ship detection is of great significance to ship safety, harbor management, and ocean surveillance in coastal harbors. The main limitations of current ship detection methods lie in the complexity of application scenarios, the difficulty in diverse scales object detection, and the low efficiency of network training. In order to solve these problems, a novel multi-target ship detection method based on a decoupled feature pyramid algorithm (DFPN) is proposed in this paper. First, a feature decoupling module is introduced to separate ship contour features and position features from the multi-scale fused features, to overcome the problem of similar features in multi-target ships. Second, a feature pyramid structure combined with a gating attention module is constructed to improve the feature resolution of small ships by enhancing contour features and spatial semantic information. Finally, a feature pyramid-based multi-feature fusion algorithm is proposed to improve the adaptability of the network to changes in ship scale according to the contextual relationship of ship features. Experiments on the multi-target ship detection dataset showed that the proposed method increased by 6.3% mAP and 20 FPS higher than YOLOv4, 7.6% mAP and 36 FPS higher than Faster-R-CNN, 5% mAP and 36 FPS higher than Mask-R-CNN, and 4.1% mAP and 35 FPS higher than DetectoRS. The results demonstrate that the DFPN can detect multi-target ships in different scenes with high accuracy and a fast detection speed.
