Portland Shipyard The Portland Ship Repair Yard is located in Oregon and is one of the most cutting edge repair facilities on the west coast. Owned by Cascade general, the Portland Ship Repair Yard is connected to the Pacific Ocean through the Columbia and Willamette shipping channel. The facilities in Oregon are constantly being updated and redesigned with upgrades to keep it up to standards. In addition, the Portland Ship Repair Yard has the biggest dry-dock in the United States. It should be kept in mind that the Portland Ship Repair Yard is known for using asbestos products in their ships. Many workers who have worked in the shipyard may have developed mesothelioma from exposure to asbestos. Asbestos was used by many ship repair companies to fireproof materials on a vessel. Workers who were involved in insulating ships have a higher chance of developing mesothelioma at their workplace. Many workers develop mesothelioma from having as little as 1 month of exposure in a shipyard. Mesothelioma, lung cancer, and asbestosis are three of the major diseases that are often associated with asbestos exposure. Other people who may be in danger of developing mesothelioma are the family members of shipyard workers. These people can be introduced to asbestos fibers when a shipyard worker came home with fibers on their clothes. Family members could’ve become subject to secondary exposure and still develop the same disease. The symptoms of mesothelioma include wheezing, persistent coughing, and chest pains. However, these symptoms can often be confused with less serious matters such as a cold or flu. Other symptoms may include neck pains, face swelling, and fever. Symptoms of this disease do not typically show until 20 to 50 years after exposure to asbestos, so early detection is important.
