AI Technical Summary

Technical Problem

Existing welfare units face challenges in remote and offshore installations due to limited terrain use, excessive weight, structural integrity issues, and spillage risks, particularly when lifting units with full waste tanks, which complicates deployment and retrieval, and requires frequent certification of lifting mechanisms.

Method used

A welfare unit with a one-piece monocoque construction and integrated frame elements, featuring a single attachment point at the roof apex for lifting, eliminating the need for external frames and reducing lifting height, and incorporating corrosion-resistant materials to enhance durability and stability.

Benefits of technology

The solution provides improved structural integrity, reduced lifting height, and corrosion resistance, allowing safe and efficient deployment and retrieval with minimal maintenance, while preventing spillage and odor infiltration.

Abstract

The present invention describes a welfare unit (1), such as a toilet, shower, or storage facility, having an enclosure defining a one-piece body (2) with an access door (7) and attachment means (4) connecting the enclosure / welfare unit to a lifting hoist. The attachment means is adapted to transmit lifting forces evenly throughout the enclosure via frame elements (25) integrally molded with the one-piece body, providing a rated lifting weight (safe working load) of the enclosure substantially greater than the enclosure's inherent weight, including the access door and accessories associated with its functionality. Furthermore, a method for forming a welfare unit comprising an enclosure with a frame element integrally formed therein is described. The method includes preferred molding steps, namely, forming the attachment means to a lifting hoist, and selecting internal components to define the welfare unit's utility.
