Container adapted for cargo or personnel transport in marine operations, the container being substantially prismatic, cylindrical or cubic in shape, wherein the container comprises: - an internal surface and an external surface , - a rigid frame , which defines a plurality of container faces , wherein the confluence of two or more of said container faces define edge portions , wherein one or more of the edge portions are substantially chamfered, and - one or more shock absorbing corner protectors adapted for being mounted on the edge portions , wherein the corner protectors comprise an inner face and an outer face , wherein - the edge portions of the rigid frame comprise two or more beams arranged substantially in parallel to the direction of the confluence of two container faces , and - the inner face of the corner protectors comprise one inner section in the middle of two substantially equal outer sections , and at least a flange adapted for fitting in the two or more beams of the edge portions , such that the corner protectors substantially protrude from the external surface , wherein the one or more shock absorbing corner protectors comprise a elastomeric material adapted for absorbing impact energy and distributing the associated impact stresses on the rigid frame , and a flexible foam core, wherein the at least one flange of the corner protectors comprises two flange protrusions configured to self-lock the entire corner protector on the two or more beams , characterised in that the flexible foam has shape memory and wherein said flange protrusions protrude from the flange inclined towards the outer sections leaving a space for allocating the beams , in a manner the flange protrusions self-lock on the beams , and wherein the thickest part of the corner protectors is oriented substantially perpendicular to the chamfered face of the edge portions . - an internal surface and an external surface , - a rigid frame , which defines a plurality of container faces , wherein the confluence of two or more of said container faces define edge portions , wherein one or more of the edge portions are substantially chamfered, and - one or more shock absorbing corner protectors adapted for being mounted on the edge portions , wherein the corner protectors comprise an inner face and an outer face , wherein - the edge portions of the rigid frame comprise two or more beams arranged substantially in parallel to the direction of the confluence of two container faces , and - the inner face of the corner protectors comprise one inner section in the middle of two substantially equal outer sections , and at least a flange adapted for fitting in the two or more beams of the edge portions , such that the corner protectors substantially protrude from the external surface , wherein the one or more shock absorbing corner protectors comprise a elastomeric material adapted for absorbing impact energy and distributing the associated impact stresses on the rigid frame , and a flexible foam core, wherein the at least one flange of the corner protectors comprises two flange protrusions configured to self-lock the entire corner protector on the two or more beams , characterised in that the flexible foam has shape memory and wherein said flange protrusions protrude from the flange inclined towards the outer sections leaving a space for allocating the beams , in a manner the flange protrusions self-lock on the beams , and wherein the thickest part of the corner protectors is oriented substantially perpendicular to the chamfered face of the edge portions . <EOS>
