1 SOLAS regulation
V/19 requires that speed and distance measuring devices shall
be fitted as follows:
-
.1 ships of 300 gross tonnage and upwards and
passenger ships irrespective of size for measuring speed through the
water (SOLAS regulation V/19.2.3.4);
and
-
.2 ships of 50,000 gross tonnage and upwards for
measuring speed over the ground in the forward and athwartships direction
(SOLAS regulation V/19.2.9.2).
2 As described in paragraph 1 above, SOLAS requires
all ships of 50,000 gross tonnage and upwards to be fitted with a
speed and distance measuring device fulfilling SOLAS regulation V/19.2.3.4 and, in addition,
a speed and distance measuring device fulfilling regulation V/19.2.9.2.
3 The Maritime Safety Committee, at its ninetieth
session (16 to 25 May 2012), taking into account the advice provided
by the Sub-Committee on Safety of Navigation, at its fifty-seventh
session (6 to 10 June 2011), agreed that both regulations should be
fulfilled by two separate devices, i.e. one speed and distance measuring
and indicating device capable of measuring speed through water and
one separate speed and distance measuring and indicating device capable
of measuring speed over the ground in the forward and athwartships
direction.
4 In line with the above-mentioned decision, the
Performance Standards for devices to measure and indicate speed and
distance, given in resolution MSC.96(72), have been amended accordingly.
These amendments are published in resolution
MSC.334(90) and apply to devices installed on ships constructed
on or after 1 July 2014.
5 Member Governments are invited to bring this
clarification to the attention of all parties concerned.
