Current Progress

0 Met with shipyard right before break and finalized all requirements for design.

0Finished preliminary Solidworks drawings

0Created FEA models for cantilever deflection and simple beam analysis

Current Design

0Durable frame constructed from I-beam steel0 Rectangular base with I-beam supports bolted to the

floor0 Steel plate welded to base support beams0 Vertical members welded with rigid L-brackets0 Vertical members to attach various clamps0 Bracing along vertical members0 Drip pan to catch and drain residual oils0 12’ x 12’ footprint0 Weight requirement of approximately 10,000lbs

Drain Pan

Clamp Assembly

0Two machined pieces with approximate radius of masts0 Three clamp diameters

03”, 6”, 14” D will accommodate all masts

0Pieces can be bolted to vertical members and tightened down on the masts0 Adjustable along vertical beam0 2 clamps: 1 near bottom, 1 above midpoint
