AI Technical Summary

Technical Problem

Existing maritime containers lack effective electromagnetic compatibility (EMC) attenuation for incoming and outgoing electromagnetic field disturbances, preventing integration of command systems, electronic warfare, and satellite links, and are costly and difficult to manufacture with aluminum sandwich panels.

Method used

A method involving the removal of the wooden floor and welding a metal floor and internal partition around the perimeter, with continuous and spot welding, to create a container with integrated communication interfaces and strong EMC attenuation.

Benefits of technology

The method enables a maritime container with guaranteed EMC performance up to 40 dB at 1 GHz, allowing integration of command systems, electronic warfare, and satellite links while maintaining structural integrity and stackability.

Abstract

Method of manufacturing a container configured to mitigate incoming and outgoing electromagnetic field disturbances, comprising: - removing the wooden floor (2) from a starting ISO shipping container (1); - stripping areas of the container for welding; - continuously welding a metal floor (9); - continuously welding around its perimeter an internal metal partition (11) forming an internal attenuation part (12); - making at least one first cut (13) in a wall of the container to receive a door assembly (14); - making at least one second cut (15) in the internal metal partition to receive a first frame (16) for a communication interface (17);- make at least one third cut (18) in a wall of the container to receive a second frame (19) for a communication interface (20); - install at least one door assembly; - install at least one first frame in the second cut; - install at least one second frame in the third cut.
