Abstract: Solar tracking assemblies and methods for tracking the movement of the Sun are described herein. The dual axis solar tracking system generally includes a foundation, a primary layer, a secondary layer, and at least one motor that controls a first and second actuator. The foundation is designed to uniformly distribute the weight of the solar tracking assembly in the absence of additional securing or structural supports. The primary layer is adapted to rotate relative to a primary axis. The secondary layer is adapted to rotate relative to a secondary axis. The secondary layer is adapted for attachment of a payload thereto which may absorb the Sun's energy.

Abstract: A modified strongback for laying pipeline offshore that utilizes a movable clamp. One end of the strongback is modified to include a travel mechanism. A pipe clamp is mounted on the travel mechanism to allow movement of the clamp as necessary to accommodate different pipe joint lengths. A mechanism for locking the clamp in the desired position is provided on the strongback.
