Feature 3 | SUBMARINE RESCUE
The pressure hull for DSAR-5 was for local sea trials and integration on board vehicle. This would share many features

in Renfrew, Scotland, for outfitting design work for a derivative DSAR 700 down to 700m. WT
and integration. That for DSAR-6 was
fabricated in the UK by Metalcraft.
One notable difference between DSAR-5
and DSAR-6 is the hatch configuration.
Whereas the South Koreans have a
dedicated MOSHIP with a below decks
decompression chamber, enabling the use
of the main transfer hatch, the Singaporean
SRV features an aft hatch to allow personnel
to be transferred under pressure to a
chamber at the main deck level.
SEA was subcontracted by JFD to
design, develop, integrate and test the
navigation, communications and control
suite for DSAR-5 and DSAR-6. The system
is software driven, but with all controls
duplicated conventionally, and facilitates
the introduction of auto heading, attitude
and depth. One feature is an underwater
modem that enables through-water
communications between the SRV and
the MOSHIP.
DSAR-5 completed in-water trials on
the west coast of Scotland in November
2008, and the submersible was formally
named ROKS DSRV II on 25 September
2008. DSRV II was subsequently
delivered to Jin Hae in South Korea
for installation and commissioning on
board Chung Hae Jin.
Classification society Lloyd’s
Register oversaw the manufacture and
testing of ROKS DSRV II, making it
the first submarine in South Korea
to be classified by the London-
based marine risk-management and
certification group.
During sea acceptance tests in the East
Korean Sea in December, the Republic
of Korea’s DSRV II achieved a dive depth
of 507m during sea acceptance tests –
the deepest recorded dive in the navy’s
history. It also completed a successful
mate with the Chang Bogo-class (Type
209/1200) submarine Na Daeyong
at a depth of 150m. The vehicle was
formally accepted into RoKN service
at a ceremony on board Cheong Hae Jin
on 22 December.
DSAR-6 was officially named at a
ceremony at Farlie Quay on 17 December DSAR-6 is now in Singapore, being prepared for local sea trials and integration on board
2008. It is now in Singapore being prepared Swift Rescue (shown here) prior to entering service.
