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.
