ROV/AUV buoyancy - technical data
Please contact us with your specific project requirement. These tables, however, provide an overview of typical densities at particular operating depths for BOE’s two ROV/AUV systems.

ROV/AUV external finishes 3-5mm spray applied elastomer is the most common finish for ROV/AUV blocks. High gloss yellow, orange, red or white are standard while other pigments are available by specification.
An integral GRP skin is also used for certain applications and this finish is formed within the production tool to become a structural component of the module.
Rotationally moulded polyethylene shells are an option when a reasonable quantity of blocks is required. Typical thicknesses of PE shells range from 6-14mm.
