Kolkata: Garden Reach Shipbuilders & Engineers Ltd (GRSE) has secured a patent for an indigenous process covering vessel block alignment and edge preparation for naval platforms. The patent, titled “Process for Vessel Block Alignment and Edge Preparation for Naval Platforms,” was granted on October 1, 2026.
The development marks a step forward in GRSE’s efforts to strengthen indigenous technological capabilities in defence shipbuilding. The patented process is designed to improve precision, efficiency and quality during the construction of naval vessels.
The innovation focuses on an important stage of warship manufacturing, where accurate alignment of structural blocks and proper edge preparation are essential for assembling the vessel’s hull.
GRSE Patent Targets Precision in Warship Construction
Warships are built by assembling multiple structural sections, commonly known as blocks, to form the complete hull. The accurate positioning and alignment of these blocks are essential for achieving the required structural integrity and quality during construction.
Edge preparation is another critical step in the assembly process, as it helps ensure that adjoining sections can be properly joined.
According to GRSE, the patented process provides an indigenous approach to vessel block alignment and edge preparation for naval platforms.
The process aims to support improvements in:
- Precision: Enhancing the accuracy of block alignment during vessel construction.
- Construction efficiency: Improving processes involved in assembling naval platforms.
- Quality: Supporting consistency in the preparation and joining of structural sections.
- Indigenous manufacturing: Strengthening domestic technological capabilities in warship construction.
The patent covers a specialised process associated with naval platform manufacturing, an important area of advanced defence shipbuilding.
GRSE Strengthens Indigenous Defence Shipbuilding Innovation
GRSE said the patent reflects its continued focus on indigenous innovation and technological development in the defence shipbuilding sector.
The development is intended to strengthen the company’s capabilities in manufacturing advanced naval platforms and contribute to India’s domestic defence production ecosystem.
By developing indigenous processes for specialised shipbuilding activities, GRSE is continuing its efforts to improve manufacturing capabilities and support technological advancement in naval vessel construction.
GRSE Continues Innovation Push Through GAINS Initiative
GRSE has also been expanding its focus on innovation through initiatives aimed at encouraging new technologies and solutions for the shipbuilding sector.
In August 2026, the company launched the fourth edition of its GRSE Accelerated Innovation Nurturing Scheme (GAINS). The initiative is designed to encourage innovative solutions addressing challenges and emerging requirements in shipbuilding.
The scheme reflects GRSE’s broader approach to promoting technological development and supporting innovation within the maritime and defence manufacturing ecosystem.
The newly granted patent adds to these efforts by highlighting the development of an indigenous process for a specialised stage of naval platform construction.
