SUMMARY

| Executive
summary: |
This document is
submitted to
request that the six
mile radius of
arc (Area to be
avoided) described
around the Alphard
Banks on BA chart
2083 be abolished,
as the traffic
separation scheme off
Alphard Banks
as described at annex 9
to COLREG.2/Circ.44
serves the
purpose originally
intended by the
aforementioned
warning area. |

Background
1 South Africa submitted a proposal
to
the forty-second session of the
Sub-Committee on
Safety of Navigation to consider
the establishment of
two proposed traffic separation
schemes at the
Alphard Banks and the FA Platform
off Mossel Bay on
the southern coast of South Africa.
2 The schemes were eventually approved
by the forty-third session of
the Sub-Committee on
Safety of Navigation in July
1997 and submitted for
approval to the Maritime Safety
Committee (MSC) at
its sixty-ninth session where
they were adopted in
accordance with the provisions
of resolution
A.858(20).
3 Subsequently, the South African
Maritime Safety Authority was
informed by the
International Maritime Organization
(IMO) that an
area to be avoided around the
Alphard Banks (see
chartlet at annex) had been brought
to the attention
of IMO by the United Kingdom
Hydrographic Office. The
"Area to be avoided"
appears on BA chart
2083 as a six mile radius centred
on the Alphard
Banks and intrudes by approximately
two nautical
miles into the northern traffic
lane of the Alphard
Banks separation scheme. It was
considered that the
intrusion of the original circle
of arc, or
"Area to be avoided"
into the northern
traffic lane of the Alphard Banks
scheme, would
possibly introduce an element
of uncertainty to
mariners passing through this
lane.
For reasons of economy, this document is
printed in a limited
number. Delegates are
kindly asked to bring
their copies to
meetings and not to request
additional
copies.
