We just returned from performing a stern tube bearing carrier alignment on a large container vessel currently in construction at a leading US shipyard. The one-meter diameter bearing carriers needed to be set to specific tolerances with respect to an established datum line along the longitudinal axis of the ship. Historically, this was accomplished using optics, piano wire and depth gauges. The procedure was time consuming and considering the sizes of some of the vessels being fabricated, performing an alignment was tedious and time consuming work. Sunlight on the hull can cause considerable movement; therefore a faster alignment process would be desirable. Therefore, we were asked to bring in the Easy-Laser E950-B bore alignment system. The quick setup and operation of this wireless laser alignment system made taking bore straightness readings a breeze, saving valuable time on a warm sunny morning in dry dock. The client was pleased with the speed with which the job was performed and the ease of understanding results—a testament to the straightforward design of the E-Series software.
