Indian shipyards are intensifying efforts to match the speed and efficiency of their European counterparts through the adoption of advanced construction techniques. One such method is the integrated construction approach, which has already shown promising results in streamlining shipbuilding processes in India.
This method involves the modular construction of ships where different sections like the hull, superstructure, and internal systems are pre-fabricated as large blocks. Each block, weighing approximately 250 tonnes, is meticulously engineered to include the necessary cabling and piping, ensuring that once assembled, these components align perfectly for welding and final integration. This approach not only reduces construction time but also enhances the quality and precision of the build.
A prime example of this strategy in action is the construction of the Nilgiri-class warships. These vessels represent some of the most sophisticated naval ships India has ever produced, being enhanced versions of the earlier Shivalik-class frigates. The shift to the integrated construction method has dramatically cut down the timeline from keel laying to commissioning. The initial Nilgiri-class ships took 76 months to complete, which is already a significant reduction from the 108 months average for the Shivalik class. However, the latest advancements promise even quicker results, with projections indicating that the subsequent four ships in the series will only require 60 months to be fully operational.
This acceleration is not just a testament to improved construction methods but also reflects a broader strategy of capacity enhancement in Indian shipyards. The adoption of such techniques allows for:
- Reduced Construction Time: By building in modules that can be worked on simultaneously, the overall construction timeline is significantly shortened.
- Quality Control: Precision in block construction leads to fewer errors and rework, ensuring higher quality ships.
- Cost Efficiency: Faster build times and less waste mean more cost-effective shipbuilding processes.
Indian shipyards are also focusing on upgrading their infrastructure, investing in modern equipment, and training their workforce to handle these advanced techniques. This push is part of a larger vision to elevate India’s position in the global shipbuilding market, where currently, nations like China, South Korea, and Japan dominate.
