analysis

Vessel design objectives seem, at times, to be in opposition to each other. It’s only through close study with the proper tools, experience, and planning that the optimum solution can present itself. Over the past 22 years, Elliott Bay Design Group (EBDG) has been providing our clients with a wide range of analysis services. The art and science of naval architecture is governed by the environments of vessel operations, government regulations, shipyard capabilities, and economic objectives.

We help our customers navigate through the competing factors, using the latest in state-of-the-art tools, selectively applied. To support waterborne transportation studies, EBDG has created ShipCalc, a proprietary modeling software that assesses the capital and operational costs of different vessel scenarios as identified by service and implementation strategies. Using physics-based design principals to model vessel performance and capacity, we help customers evaluate a variety of marine transportation challenges.
