Longshore and Harbor Workers' Compensation Act (LHWCA): Overview of Workers' Compensation for Certain Private-Sector Maritime Workers [Updated March 10, 2021] [open pdf - 1MB]
From the Summary: "The Longshore and Harbor Workers' Compensation Act (LHWCA) is a federal workers' compensation program that covers certain private-sector maritime workers. Firms that employ these workers are required to purchase workers' compensation or self-insure and are responsible for providing medical and disability benefits to covered workers who are injured or become ill on the job and survivors' benefits to the families of covered workers who die on the job. The LHWCA is administered by the Department of Labor (DOL), and all benefit costs are paid by employers and their insurance carriers. In 2017, more than $2 billion in LHWCA benefits were paid to beneficiaries."
