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. Each 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, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 19019 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 300, Sea-going vessels and marine technology, in collaboration with Technical Committee ISO/TC 8,
Ships and marine technology, Subcommittee SC 9, General requirements, in accordance with the Agreement
on technical cooperation between ISO and CEN (Vienna Agreement).
INTERNATIONAL STANDARD ISO 19019:2005(E)

Sea-going vessels and marine technology — Instructions for
planning, carrying out and reporting sea trials
1 Scope
This International Standard provides ship owners, designers, shipbuilders and trial crew with basic instructions
for the planning, carrying out and reporting of sea trials.
This International Standard provides general information for achieving a unified format for sea trials to be
executed as identified in the contract.
This International Standard is applicable to sea trials generally adopted for types of mechanically propelled
vessels as indicated in Annex B.
This International Standard is not applicable to submarines.

3 General information on sea trials
3.1 General
The aim of sea trials is to demonstrate that the vessel is in conformity with contract and with requirements of
classification societies and flag authorities.
Sea trials are mainly functional, to demonstrate operation, behaviour, energy consumption and required power
of the vessel, her systems, equipment and components. Sea trials shall be executed in a suitable area in
order to avoid risks of collisions, damages and interruptions.
Sea trials are of two sorts:
a) globa
