[AusNOG] SEA-ME-WE 3 cut again

[Peter Hansen]

Hi All,

Latest update we’ve received:

"Cable ship ASEAN Explorer has been mobilized for the S3.3 repair.  Based on the preliminary POW, cable ship is expected to set sail to repair site on 21 Dec 2014 after completion of Indonesian clearance.
 Expected repair completion: 25 Dec 2014 (Tentative)
 More updates will be provided when information is available."

Regards,
Peter

when I was studying geology back in the day, cable cuts in Hawaii were a valuable tool to map underwater turbidity flows associated with earthquakes to help understand slope stability....

The challenge with SMW3 is that the segment from about 200km south of Indonsia all the way to Singapore is in less than 60m of water depth (about 1,400km).  Ideally cables are deeper than 2,000m of water depth away from anchors and long-line fisherman :)

The other challenge is that some sections of this route it is almost impossible to bury due to the ocean floor being rocky and not ideal for burial.  Sometimes there is an alternate route, but it would add significant latency, something that people in 99% of circumstances prefer.  The 1% of the time they don’t mind latency is when the cable is not functioning due to a shunt fault or a cut, which could have been avoided if they went the more safer, less commercial route :)

There is a history of intentional cable cut/theft in these waters by people initially interested in the perceived copper/raw materials.  There is a notorious stretch between two (2) islands in which nearly all cables pass and due to the rock formations and depth these cables can’t be buried and are easily damaged either intentionally or otherwise.  Despite the investment in education and armouring things still happen.  An example can be found here:

http://www.thejakartapost.com/news/2013/06/29/indosat-spends-rp-10-billion-replacing-stolen-underwater-cable.html

Also I think last time there was a combination of factors being a shunt/cut and a repeater “pop” needing two (2) permits to complete.  Others on the list would have a better background as to what happened last time and what is happening this time.  I will make some calls and get an ETA.

Cheers

That's my understanding of the last delay, I assumed it might face similar issues this time.

Hopefully I'm just being a little too pessimistic!

Wasn't the last cut's delay due to the repair boat not being able to enter Indonesian waters?
ITNews seems to think that won't be an issue any more and it should be repaired by 6pm Perth time.

Given the fault location it's hard to imagine it being repaired much faster than the last cut.

Hi, FYI

SEA-ME-WE 3 was cut again this Sunday.
Were seeing double the roundtrip that we saw when compared the the outage last year July which took eight weeks to repair.

As spoke over the phone, the increased in latency or RTD is related to submarie cable fault [SMW3 S3.3(Perth - BU)]. Path between Korea and Australia has been changed to traversing KR <> JP <> AU/Sydney <> AU/Perth, thus additional delay is expected.

The fault has been detected on 11/30 0339 UTC and is located at about 1155 km from Singapre TUAS cable station near tha Jakarta branching unit. Cable repair schedule is to be advised once available.
