Theoretically. If there’s enough gas perking to the surface a ship could — again THEORETICALLY — lose buoyancy and sink. It’s like trying to float an object in beer foam.
But the leak is over 70m down (240 ft). Depressurizing that pipeline from that depth probably wouldn’t cause that kind of an affect at the surface.

Has anyone contemplated that depressurizing a damaged underwater pipeline will result in flooding which will make repair work even more difficult? Winter is coming and we want that pipeline operational ASAP. The line is weight coated to prevent flotation.
