Convection modules loaded on a false deck inside the M/V Ocean Atlas

Project Summary

In April 2007, a total of 24 large convection modules were to be loaded onto the heavy-lift project ship Ocean Atlas. These modules weighed between 60 and 120 t and because direct stacking was not allowed, false support decks were to be installed in the vessel's holds. Argonautics Marine Engineering was hired to design these false decks and their supports and to design the lashing of the convection modules - all with very short notice. The false decks were limited to sets of steel cross beams in way of the module support points only, resting on 8 ft high stacks of crane mats and timbers. The final construction drawings were delivered on time to ensure the installation of the decks and loading of the modules could take place without any delays. In Houston, TX, the convection modules were loaded on the false decks and successfully delivered to the port of Ras Laffan after an uneventful voyage.       

Scope of Work

The project scope included:

• Design the false decks and their supports, using available materials;

• Provide detailed construction drawings;

• Design the lashing of the modules, using clips and lashing chains.
