BoreHulls

BoreHulls are a class of modular hull systems used in marine and subsea platforms. The concept relies on bore modules—cylindrical hull sections that can be connected end-to-end to form a continuous pressure boundary for crewed submersibles, ROVs, AUVs, or hybrid platforms. Modules are fabricated from lightweight, high-strength materials such as carbon fiber reinforced polymer and aluminum alloys and are equipped with ballast, pressure bulkheads, and integrated power and data conduits. Seams employ gasketed flanges and quick-connect couplings to enable rapid on-site assembly, maintenance, and reconfiguration.

Design and engineering: BoreHulls emphasize scalability and resilience. Modules are dimensioned to provide scalable length and cross-section while maintaining a common internal pressure boundary. Each module hosts ballast tanks, instrument bays, and optional life-support or payload compartments. The joints are designed to transfer load and seal against seawater, with redundant bonding and electrical interlocks. The modular approach allows operators to reconfigure hulls for different missions without welding or heavy lift operations; damaged modules can be isolated and replaced.

Applications: BoreHulls are used for research and exploration platforms requiring adaptable hull geometries, including AUVs and ROVs, shallow-water survey craft, temporary underwater habitats, and salvage or lifting operations where different payloads are needed.

History and variants: The BoreHull concept originated from marine modular-design programs in the early 2010s. Variants include BoreHull S (surface/submersible), BoreHull M (mobile hull for mixed-use platforms), and BoreHull X (extended-length configurations). Critics note challenges in joint reliability and material corrosion, while supporters point to reduced lead time and greater mission flexibility.
