Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bodies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission (IEC) on all
matter-s of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 6115 was prepared by Technical Committee ISO/TC 8,
Shipbuilding and marine structures.
This second edition cancels and replaces the first edition (ISO 6115 : 1981) of which it
constitutes a minor revision.
Annex A forms an integral part of this International Standard; annexes B and C are
given for information only.

powered drive.
31 nominal size: Drum load on the trawl rope drum, in
tonries, as stated in table 1, for a Single-drum trawl winch.
The winches are used for hauling-in, paying-out and holding
the trawl rope while fishing by means of trawling fishing gear.
NOTE - For a double-drum trawl winch, the nominal size corresponds
to twice the drum load stated in table 1.
When equipped with additional auxiliary drums, they may also
be used for auxiliary operations when hauling-in, paying-out
