Technical report: MV Estonia bow visor – calculation of weight and volume

The weight, CoG and volume of the bow visor of MV Estonia has been calculated based on the original drawing from Meyer Shipyard. The weight was calculated to 64.0 tonnes with a LCG of 5.25 m from frame #156 and VCG of 6,99 m above DWL.

Calculated weight and centre of gravity differs from earlier information with abt. 10% regarding both CoG and weight. The weight was later determined, by weighing of the salvaged visor, to be 65,5 tons, abt. 2% difference from the calculated result. 

Based on the CoG of the visor and the volume of possible air pockets, it is not possible to dismiss that the visor under certain circumstances could float. It cannot be determined whether an air pocket would occur or not and it is not possible to with accuracy say for how long time an air pocket would delay the sinking of the visor.
