A listing of cable ships around the world and their approximate
locations (as of a couple of months ago) is available from the
Submarine Telecoms Forum, at


and click on "Issue 29".

There just aren't that many ships in the area, or any area, for
that matter.  The regional cooperative facilities for cable repair 
and maintenance are planned based on some standard risk assessments,
and the recent quakes seem to have caused damage outside the planned

  Much of the affected cables are managed under the SEAIOCMA (South  
  East Asia Indian Ocean Cable Maintenance Agreement). I am not sure  
  how many ships they have on stand-by in the region, but probably not  
  enough to send out one ship to each of the faults, given that  
  multiple faults have been reported on most cable systems.

  I presume, the more important cable systems - those with higher  
  stakes for the SEAIOCMA signatories will get repaired first followed  
  by others.
