Abstract: An improved system for sealing a keel cooler to a hull of a vessel, of the type including a plurality of flow channels for exchanging heat between vessel water flowing in the channels and surrounding sea water; nozzles extending from ends of the keel cooler, for allowing the water to flow between the vessel and the keel cooler, companion fittings including at least one o-ring positioned on its inner wall, and including an opening for receiving each nozzle of the keel cooler; a bushing for allowing the o-ring of each nozzle and the o-ring of each fitting to seal against walls of each bushing; and each bushing having an eccentric circular wall, so that when the fitting openings on the hull are not the same distance apart as the nozzle openings, the bushing is rotatable to define a complete fluid seal.

Abstract: The pipeline locator/coordinate mapping device is a tool to be utilized for the location of pipeline coordinate data points via a Cartesian coordinate system. The device will initiate from a known origin or datum with horizontal, X coordinate; longitudinal, Y coordinate; and vertical, Z coordinate respectively being equal to zero. As the device traverses internally through the pipeline, away from the origin or datum, a time increment will correspond to the recorded data, pressures and accelerations, and hence allow the positional coordinate points along the pipeline to be derived in three dimensional space for incremental positions versus time. By analysis of the data displacements from the origin or datum in succession, the pipeline may be located and mapped in an as-built position from a frame of reference, i.e. longitudinal and latitudinal coordinates along the earth.
