Hello Mafioso,
On GE, the L x B are around 74m x 9 m, with a long hold.
I wonder these two hulls could be ex Soviet naval ships 'Polnochniy' class, group A.
USSR had some naval bases in the area (Hanish anchorage, Socotra) so it could be two decommisioned naval ships.
Just my opinion, to be confirmed !
Regards,
Yvon
