They have cleared the ships that were in front and are sending in tugs to help, but they may not be enough..................
Stating: “hook a gigantic ship up to another gigantic ship” isn’t something that is going to be done in some simple fashion even if it is at all possible, taking into count the forces that would be introduced to both ship’s anchoring points. The chains would need to be equally taut distributing the force in an as equitable way as possible so who knows if it is even feasible?
Obviously, it would have to be the ships lined up to the aft of the stuck ship that could be brought into service as giant tugs.
When you are a professional know it all anything is possible. High five! ;0)
