Breaking news from Australia:

THE Australian navy is standing by to help rescue two people aboard a civilian submarine rescue craft stranded on the ocean floor off the West Australian coast.
An Australian Submarine Rescue Vehicle (ASRV) ran into difficulty about midnight when the winching system failed as it was being recovered during certification trials.
The Australian Defence Force says the two personnel aboard the vessel, called the Remora, were in no danger.
The Remora, operated by the civilian diving contractor Caldive, was lowered, in accordance with safety procedures, to the sea bed and was currently sitting in 130 metres of water.
The two people aboard remain connected to the mother ship, Motor Vessel Seahorse Standard, by a secondary cable which gives them power and allows them to communicate with the vessel.
It may be able to be used for lifting the Remora in an emergency.
The Australian Defence Force (ADF) says the frigate HMAS ANZAC, navy clearance divers and medical personnel were standing by to help Caldive if needed.
"The current weather conditions preclude a controlled recovery of the ASRV at this time, but an emergency option remains available if required," ADF said in a statement.
Caldive is currently developing a rescue plan with help from the Royal Australian Navy...
...But it was taking part in a navy submarine escape exercise in the Western Australian exercise areas at the time of the incident.

Here's a picture of the Remora:


Caldive appears to be a subsidiary of Helix. For now, it looks like the situation is well in hand.

Staying at PD...

Update 2210 04 Dec: It looks like the Remora and M/V Seahorse Standard are frequently used for sea trials and submarine rescue exercises. There are many pictures of the Remora here and here, one of which shows her on her support ship.


The last coastal warning for the Seahorse Standard was from 21 Nov, which said:

FM RCC AUSTRALIA 212120Z NOV 06
AUSCOAST WARNING 309/06 SW.COAST

The Sunday Times has this article discussing the capabilities of the Remora.

Here's the ISMERLO (International Submarine Escape and Rescue Liaison Office) homepage, which might have some updates if any international forces are needed.

Update 2236 04 Dec: The men have been rescued:

TWO man are safe and unhurt after their submarine rescue craft because stranded on the ocean floor off the West Australian coast.
The Australian Submarine Rescue Vehicle (ASRV) was carrying out certification training 40km north of Rottnest Island when one of the two cables in its winching system failed overnight.
The craft was lowered 130 metres to the sea floor as a safety measure while a rescue plan was worked out.
Commander of the Submarine Force Elements Group, Commodore Richard Shalders, said the men were rescued at 12.50pm (WDT), after the pod was lifted to 15 metres below the surface.
"The two divers were brought out of the pod, assisted by some divers from the surface, at about 15 metres below the surface,'' he said.
"They were given assistance with scuba tanks from below the water.''
The men were uninjured but receiving medical attention on HMAS ANZAC, he said.

This has been a test of the submarine blogger "Breaking Submarine News Response" service. Had this been an actual submarine-related story that took more than an hour or so to happily resolve, this blog, as well as the group submarine blog Ultraquiet No More, would have been your most reliable sources to explain what the media was trying to say. We now return you to your normally-scheduled submarine blonde joke:

"How do you flood a submarine full of blondes?"

"Knock on the door."

Update 2220 06 Dec: As some commenters have mentioned, the Remora ended up parting her cable and going to the bottom after the crew was rescued. Here's a story about plans to recover the mini-sub.
