Elliott Bay Design Group Performs Finite Element Analysis For Arco

Elliott Bay Design Group (EBDG) of Seattle, Wash., offers finite element analysis to help its clients with the challenge of maintaining their escort tugs' deck equipment and ability to handle higher loads.

EBDG provided finite element analysis for Arco, analyzing parts of the bow mooring arrangements on the tanker Arco Texas.

Elliott Bay previously performed a similar analysis for Arco on some of the stern mooring points aboard the tanker Arco Anchorage, looking at loads experienced during ship maneuvering assistance provided by large ship-assist tugs. In both cases, the analysis included onboard inspection of the vessel by a team from EBDG, ultrasonic testing, and verification of supporting structure for all deck fittings.

"We created a finite elements model," said Elliott Bay President John Waterhouse, "which is analyzed for different loads to determine the safe working load under the most extreme anticipated conditions.

We provide a complete report to the client, so they can make decisions on potential vessel modifications to accommodate the increased loads from these new-generation tugs." For more information on Elliott Bay Design Group Circle 73 on Reader Service Card
