“…The outlook for the Indian shipbuilding sector was enhanced by expanding international trade and robust substitute market. The Indian shipbuilding sector has changed from being reliant on governmental contracts until the late 1990s, concentrating instead on the specialized offshore market [6].…”

Indian shipbuilding has a long history in the maritime industry dating back to the origin of civilization. India's shipbuilding sector is primarily concentrated in its coastal regions. Due to capacity constraints and decreased shipbuilding prices in emerging nations, shipbuilding activities has changed. This has created fresh opportunities for the Indian shipbuilding industry. The prospects for the Indian shipbuilding sector are improved by rising global trade and strong need for modern boats. This study investigates the use of Predictive Maintenance as a Service on the Industrial Internet of Things (IIoT-PdMaaS). Artificial intelligence (AI) in the maritime industry has numerous major benefits, including improved decision-making analysis, automation, security, route planning, and increased efficiency. So, Pd-MaaS using IIOT (Convolution neural network (CNN) with Ensemble Boosted Tree Classifier) framework was developed in this study. This research shows 88.3% accuracy of CNN output for confusion matrix implying a positive connection with our proposed model for Indian ship building industry

“…Welding is an important step in hull assembly and an important factor affecting the quality of the hull. [4][5][6]21 Many stations and processes in the processing of sub-assemblies and unit-assemblies in shipbuilding must rely on welding. Most of the subassemblies and unit-assemblies of shipbuilding enterprises still use the traditional manual welding method, which has low welding efficiency, low degree of automation and high labor intensity.…”

In shipbuilding, welds in sub-assemblies and unit-assemblies are long and various type. The robot arm needs the gantry movement to cooperate with the welding operation. However, there are joint redundancy and double-arm coordination problems, which cause difficulties in the welding trajectory planning. This paper proposes a strategy of decoupling the dual-arm system into a single-arm system for separate planning and prioritizing joint motion, and conducts welding trajectory planning research based on Matlab’s Simscape Multibody. Firstly, the 3D model of the welding workstation is established, its structure, the operation mode of the joint link and the degree of freedom are analyzed. The 17-DOF welding workstation is decoupled into a single-arm 9-DOF system, a kinematic model is established, kinematic analysis is carried out. The Matlab robot toolbox is used for simulation verification. Then the discretization of weld types and poses in sub-assemblies and unit-assemblies workpieces is analyzed. Finally, the welding workstation and workpiece model are imported into Simscape Multibody of Matlab to simulate the trajectory planning of different types of welds. The simulation results prove the effectiveness of the strategy and have certain reference significance for on-site welding in shipbuilding.
