Prudential-Grace Lines Names Renehan VP— To Head LASH Program Lawrence A. Renehan Lawrence Arthur Renehan has been appointed vice-president of Prudential-Grace Lines, Inc., in charge of the new LASH program, it was announced by Edmund J. Camuti, executive vice-president. LASH (lighter aboard ship) is a revolutionary concept of totally modular ocean cargo transporta- tion utilizing large, pre-loaded barges or lighters. The LASH sys- tem was conceived and designed by the New Orleans naval archi- tectural firm of Friede and Gold- man, Inc. Prudential-Grace is the pioneer of this unique transporta- tion system. The company expects delivery early next month of the first of five LASH vessels for serv- ice in the American merchant ma- rine. Mr. Renehan has extensive ex- perience in the maritime industry, and comes to Prudential-Grace after five years at International Paper Company, where he was di- rector of export and marine serv- ices. It was in this capacity that Mr. Renehan actively led the way for the adoption of the LASH concept for hauling paper and wood pulp. He supervised its develop- ment and directed all LASH ac- tivities for the company. Previous- ly, he was vice-president of South- ern Star Shipping Company, a bulk cargo carrier. Mr. Renehan began his career with Farrell Lines as a seagoing cadet, and he quickly worked his way up to command of cargo ships. He came ashore in 1956 to become marine superintendent and assis- tant to the president of Farrell Lines. Mr. Renehan is a graduate of Kings Point Merchant Marine Academy.
