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.

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) global trials, which include propulsion trials, manoeuvring trials, structure vibration tests and noise level
tests;
and
b) system trials, which include those non-global trials that cannot be done as quay trials, e.g. anchor-
handling tests.
Only global trials and certain system trials are covered by this International Standard.
If necessary, the measured data should be recorded continuously, e.g. using a computer with a certain
frequency of sampling (e.g. frequency of 1 Hz for speed trials). It is important to carry out an uncertainty
analysis.
3.2 Responsibility for sea trials
The shipbuilder is responsible for planning, conducting and evaluating the sea trials.
Trials may be conducted by institutions acknowledged as competent to perform those trials, as agreed
between the shipbuilder and the owner.
Instruments and equipment to be used on trials shall be calibrated and documented as traceable to
international standards of measurement.
A trials report shall be prepared with necessary recorded data sheets, as well as all terms of acceptance, in
accordance with Annex A.

ISO 19019:2005(E)
The individual sheets of the trials report shall be signed by the participants, confirming that it correctly reports
the trials results.
The trials report original shall remain in possession of the shipbuilder, and authentic copies shall be delivered
to the owner and the Classification Society, as applicable.
3.3 Demonstration of operability
Some systems, such as ship propulsion and control systems, can be shown to operate in their design modes
only at sea. This demonstration of operability verifies that
a) all systems are correctly connected,
b) the mode of operation and conduct of the systems agree with specifications,
c) there are no obstructions, leakage or other symptoms of malfunction.
3.4 Demonstration of performance and economy
During sea trials concerning the propulsion system, the aim is to confirm that the agreed power rating is
attained and that the corresponding ship speed and propulsion engine output are those stipulated by the
contract and correspond to speed and power of propulsion model tests, if available.
These trials shall be carried out in a specified reference load condition.
3.5 Demonstration of endurance
During endurance trials, the aim is to verify the ability of the system to operate in the specified mode for the
time necessary to develop thermal equilibrium conditions and to allow detection of any inadequacies.
3.6 Applicability
For economic reasons and technical interest, it is convenient to analyse which trials should be performed on
each type or series of ships (sister ships in series).
Lists of trials recommended for first-of-a-class that can be omitted for sister ships shall be specified in the
contract.
Annex B presents Table B.3 which indicates in general the trials for different types of ship. In each case and
taking into account specific conditions of each ship, those trials which are to be conducted shall be specifically
defined in the contract.
4 Planning of sea trials
4.1 Actions required in preparing for sea trials
The shipbuilder responsible for sea trials shall carefully plan these trials, so they are carried out with the
necessary safety measures in an accessible and adequate geographic area, in the strict minimum period of
time and with unequivocal results accepted by all participants.
Planning shall assure that trials are carried out with respect to the following items.
a) All permits and certificates needed to go to sea have been obtained.
b) All needed insurance policies have been obtained.

the sea trials condition, in accordance with 74 SOLAS Convention, as amended.
h) Provisional calibration of magnetic compass has been completed.
i) Calibration of the radio direction finder has been completed, if installed.
The actions indicated in h) and i) may be performed just before all other sea trials.
4.2 Sequence of sea trials
An example of sequence of sea trials is given in Annex C.
4.3 Safety precautions
Sea trials shall be held only after a careful check of all ship safety devices.
There shall be sufficient lifeboats and/or life-rafts and lifejackets for all personnel on board, their number and
make shall be in accordance with the requirements of the Maritime Authority of the trial area.
All personnel on board shall be told what to do in case of abandoning ship, in particular how to use lifejackets.
A list of all personnel on board shall be communicated to the Maritime Authority of the trial area.
Everyone on board shall be assigned a station in case of fire alarm, flooding and abandoning ship; all these
details shall be indicated in a provisional muster list.
All fire detection and fighting systems shall be installed and operative.
All bilge systems, fixed and portable, shall be installed, tested and operative.
All alarm, safety and warning devices shall be installed, tested and duly identified.
All external communication devices, both normal and emergency, and corresponding power feeders shall be

4.6 Final meeting
A final meeting involving the owner, the shipbuilder and all concerned authorities, shall be held after sea trials
are completed, in order to finalise the acceptance protocol.
5 Propulsion trials
5.1 Speed trial
5.1.1 Purpose
A speed trial is held to verify fulfilment of contractual obligations regarding ship speed and shaft power at
certain draughts (preferably related to ship model test draughts). The relationship between ship speed, shaft
power, shaft revolutions per minute and/or propeller pitch settings for controllable-pitch propellers should take
the form of plots or tables.
5.1.2 Trial specification
Whenever possible, execution and analysis shall be in accordance with ISO 15016.
If no specific conditions are invoked by the contract, speed trials shall be conducted with propulsion engines
delivering normal continuous power, and at other speed points corresponding to lower powers which are
intended to be used in future operation of the ship, and which may be used to work out shaft rotational speed
tables and/or propeller pitch settings, as appropriate. Reduced loading of the propeller shall be taken into
account.
When an overload trial of main engines has not been held during factory acceptance tests, it may be held
during this trial if the requested technical conditions are met. Reduced loading of the propeller shall be taken
into account.
Corrections on main engine performance due to differences between trial conditions and contract reference
conditions shall be established in accordance with ISO 3046 (all parts).
During speed trials, any propulsion engine power take-off for auxiliaries which are not part of the propulsion
system shall be clearly identified.
For propulsion engines with maximum continuous power above 2 000 kW, a torsion meter is recommended
for measuring power output.
5.1.3 Restrictions to the execution of the trial
Whenever possible, water depth in the trial area shall be in accordance with ISO 15016.
