Northern
California Section September 14, 2005 Historic Ship Tours Members of SNAME's Northern California Section and ASNE's Golden Gate Section gathered together on September 14th, in Jack London Square, Oakland for tours aboard two historic ships: US Coast Guard Lightship and The Potomac. The US Coast Guard Lightship, WLV 605, was originally commissioned as the Overfalls in 1951 and served as the station lightship off Delaware and Cape Mendocino, California. Renamed Relief, she served another six years as the relief ship for all of the west coast stations before being retired in 1975. The US Lighthouse Society currently maintains the vessel. The Potomac was originally built as the US Coast Guard cutter Electra in 1934. The vessel was chosen to become the Presidential Yacht for Franklin D. Roosevelt, and was re-commissioned as the Potomac by the US Navy in 1936. The Potomac continued in this service until FDR’s death in 1945. For the next thirty-five years the yacht passed through numerous ownerships, was eventually seized on suspicion of marijuana smuggling, and sank alongside a pier at Treasure Island in San Francisco Bay. Potomac was bought at auction by the Port of Oakland and has been painstakingly restored through grants and donations. The Potomac Association currently maintains the yacht. Following these historic ship tours members of the professional societies and students from the University of California, Berkeley and California Maritime Academy who were in attendance socialized and enjoyed dinner at the Tony Roma’s restaurant.
Philadelphia
Section September 21, 2005 Hendrik F. Van Hemmen presented his paper, “A Proposal for a Joint Industry Effort at Improving Bilge Oily Water Separator Operation and Design” at the Philadelphia Section Meeting which took place on September 21, 2005. The presentation discussed the problems associated with design and operation of Oily Water Separators (OWS) and outlined a proposal for a joint industry effort at arriving at more effective and user friendly designs and operational methods. Oily Water Separator systems, while standard shipboard equipment for over two decades, are just the beginning of many systems that will be installed aboard ships to serve the public, rather than the shipowner or crew. Despite numerous efforts, shipboard bilge water Oily Water Separation systems fail to produce satisfactory results for owners, regulators and crews. The failure of these systems is not solely related to technical equipment design issues, but reaches back into human factors, systems design, record keeping methodologies and inspection procedures.
The joint industry effort proposed in the paper combine the input and suggestions from owners, crews, regulators, ship designers, ship operators and equipment suppliers in a neutral technical forum and aims to develop oily water separator systems that will be regarded as a fully integrated component of the ship system rather than a stand alone. Rik van Hemmen is Vice President and Partner at Martin, Ottaway, van Hemmen & Dolan, Inc. His areas of specialization include forensic engineering, vehicle design and operations, ship appraisals, structural surveys, naval architecture and project management. |
