The U.S. Supreme Court further held in the same opinion: “Our LHWCA cases also recognize the converse: Land-based maritime workers injured while on a vessel in navigation remain covered by the LHWCA, which expressly provides compensation for injuries to certain workers engaged in ‘maritime employment’ that are incurred ‘upon the navigable waters of the United States.’ 33 U.S.C. § 903(a). Thus, in Director, Office of Workers’ Compensation Programs v. Perini North River Associates, 459 U.S. 297, 103 S.Ct. 634, 74, L.Ed.2d 465 (1983), we held that a worker injured while ‘working on a barge in actual navigable waters’ of the Hudson River, id., at 300, n. 4, 103, S.Ct., at 638, n. 4, could be compensated under the LHWCA, id., at 324, 103 S.Ct., at 651.
