Saltwater Engineering performed the structural calculations for the superstructure of a diving support vessel that is being built by Merwede Shipyard under building no.: 713. The vessel is for Subsea 7 and will named Seven Atlantic.

Saltwater Engineering calculated the strength according to the Rules and Regulations of Lloyds Register of Shipping and checked the construction plans accordingly. The positioning of the superstructure on the hull will be executed by Bonn & Mees using a floating A-frame crane. The strength of the superstructure for this operation was also checked with the use of Multiframe.
