An oceangoing barge cover is provided, which is made from lightweight structural fabric but enjoys the strength and stiffness of heavier steel covers and meets the requirements of the American Bureau of Shipping. The cover is comprised of a series of units, each of which in crosssection, is in the form of a series of concave quaternary curves, to the underside of which are fixed structural beams of fiberglass encasing rebar for support. Further support is provided by pipes of a structural fabric running perpendicular to the structural beams. A hatch can be optionally provided. Weathersealing and barge affixing means are also disclosed. In a preferred embodiment, the structural elements of the cover are comprised of fiberglass or fiberglass laminate.
