*672 Tetra Technologies, Inc. and its insurance carrier appeal the award of temporary total disability benefits under the Longshore and Harbor Workers’ Compensation Act, 33 U.S.C. § 901 et seq., to an employee who was injured in a workplace accident. Following a formal hearing, an Administrative Law Judge issued detailed findings of fact and conclusions of law that were affirmed by the Benefits Review Board in a careful opinion. Petitioners argue that the ALJ’s factual findings were not supported by substantial evidence and that the ALJ used the wrong statutory provision to calculate the employee’s average weekly wage. Finding no error, we AFFIRM essentially for the reasons given by the Benefits Review Board.
