Underwater vibration uses. Vibrational technology is used commonly in underwater applications, both inland and offshore. As we noted in the Technology section, construction firms use vibrating hydraulic pile drivers to insert massive pipes, beams and anchors into the bottom. Similar technology on a smaller scale is used in vibracoring rigs, powered mainly by electric motors or pneumatics. Sonic drilling systems used in soil and rock boring also incorporate vibrational technology. Vibracoring applications. Since the 1960s various types of vibracorers have been employed to collect sediment cores in aquatic environments. The following illustrate various deployments for certain applications. Open sea deployments. In offshore waters vibracorers are typically deployed with tripods or bouyant stands for keeping the unit upright on the bottom. Applications include undersea cable and pipeline siting, oil and gas exploration, and marine geological investigations. Coastal deployments. Coastal zone projects require smaller yet seaworthy vessels with good core handling facilities. Applications include minerals exploration, marine archaeology, and beach sand replenishment surveys. Harbor deployments. In harbor situations flexible, low profile rigs that can maneuver around obstructions are an advantage. Applications include port construction, pipeline siting, and pre-dredging investigations. River and stream deployments. River and stream projects often require shallow draught vessels that are convenient to transport and launch. Applications include shoreline construction, pre-remediation studies, and sediment quality surveys. Pond and wetland deployments. Coring in isolated waters or swamps with difficult access can involved launching a boat by crane, using an all-terrain vehicle, or deploying from a boom truck Applications include sediment remediation and landfill investigations, and archaeological studies. Land deployments. On solid ground a portable tower and draw works may be set up for vibracoring. Limited applications include saturated soil and industrial waste coring. |
