However, many bucket dredges are powerful enough to rip through coral, sparking controversy among conservationists. This method is very effective for long distances, making this a popular choice for harbor dredging and creating shipping channels. Teeth are often placed at the opening of the buckets to allow them to dig more deeply into the sediment. Bucket – This method uses many separate buckets, often attached to a wheel or chain, dragged along the ocean floor to collect and remove materials, which then travel back to the vessel to be emptied.However, this method is slower than others and has been phased out by more efficient technology over time. Historically, this method has been widely used, and much of the Panama Canal was dredged this way. This device is usually suspended from an onboard crane and can remove large amounts of sediment with each scoop. Clamshell – Clamshell devices use a bucket with two sides, which close together to pick up materials from the harbor floor.There are two main types of equipment used in dredging scoop-type dredges, which lifts away sediment bit by bit, and suction-type dredges, which removes sediment at a consistent volume. Other benefits of dredging include flood prevention, restoration of onshore land, and the removal of contaminants from the sea floor.Īlthough dredging is undoubtedly necessary, there is a great deal of controversy surrounding the process, with several groups believing the process should be halted altogether for a range of environmental and economic reasons.ĭo the benefits of dredging outweigh the costs? Regular removal of excess sediment is therefore crucial for the maintenance of the shipping channels regularly used by large vessels. The global economy relies on shipping as a means of bringing trade and tourism to countries all over the world. Larger ships require a greater depth of water to access certain areas, and dredging is sometimes necessary to prevent them from running aground when they dock. The main purpose of this process is to maintain the depth of existing ports or to create new shipping channels for larger vessels. An essential aspect of harbor maintenance, dredging is routinely performed in ports around the world for a variety of reasons. Housing a 27,000 square foot showroom, 275 in water slips, and a 150 boat dry stack storage building Dredge Harbor Boat Center LLC has grown from a sandpit to a 110 acre marine facility selling thousands of pleasure boats to generations of boaters in the greater Philadelphia area.Dredging is the process of excavating sediment deposits, trash, and other debris from the harbor floor and disposing of them elsewhere. Today the Marina is still a family business run by Tammy and her brother Bill with the help of their children Lauren, Stacy, William and Robert. visited daily and continued to make a strong presence to their long standing customers and employees until his passing on July 21 2008. Tammy and Bill now perform the daily responsibilities of the Marina, but Bill Sr. In 1984 Bill Parsons children Tammy and Bill Jr. Bayliner and it's Sister boat lines Maxum and Trophy have been the principal boat lines of Dredge Harbor ever since. In 1946 the brothers became boat dealers for a company called Chris Craft, which remained their principle boat line until the New York Boat Show of 1978 where Jack Purcell convinced them to drop Chris Craft in favor of an up and coming west coast boat company called Bayliner. In the early forties the brothers Bill and Herb had developed the "sandpit" location with a few in water slips and began selling such famous boat lines as Broadwater Yachts and Greenwich boats, which they sold in varying quantities after the second world war. Dredge Harbor Marina was on its way to becoming the largest full service marina in the Delaware valley. The riverfront was being dredged and the brothers had the foresight to see the potential of the future boating needs of the area. and his brother Herb traded their interest in two cars for a down payment on a sandpit located along the riverfront.
