JMS provided complete engineering and design services for the concept through detail design of the new crane barges to support both an existing Clyde Model 28 gantry crane and a new E-Crane 3000 series gantry crane. JMS performed engineering calculations and developed design drawings in accordance with the requirements of the ABS Rules for Building and Classing Steel Barges.

- Beam: 64 feet
- Depth: 16 feet
- Deck Rating: 1,000 PSF

JMS also developed a structural and systems design package including, generator and machinery arrangement, fuel, electrical, and hydraulic system one-lines, towing arrangements, crane rail and tie-down installation, dry docking and anode plan, and a construction details package.
Following installation of the E-crane, JMS developed weight change calculations and performed a deadweight survey to determine the lightship weight of the barge. Stability calculations were prepared and submitted to ABS for review and issuance of a load line certificate.
