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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).

Introduction
This document is intended to provide means of evaluating and determining the maximum evacuation
capacity of marine evacuation systems (MES). As a consequence of MES systems being installed on large
passenger ships, there has been an increase in system capacity during recent years. This document
provides a uniform test regime while reducing the risk of injury to test personnel by reducing the
number of persons required to complete the test. The capacity determined through this document is
based on trial conditions as described in referenced IMO instruments and does not take into account
factors such as adverse weather conditions, ship-specific installations or arrangements, or the physical
capabilities of the passengers to be evacuated.
INTERNATIONAL STANDARD ISO 16707:2016(E)
Ships and marine technology — Marine evacuation systems
— Determination of capacity
1 Scope
This document specifies a procedure for the evaluation and determination of the capacity of a marine
evacuation system as required by the International Maritime Organization Life-Saving Appliance Code
(LSA Code) and as an alternative to the procedure specified in Resolution MSC.81(70) part 1/12.6.1.

3.3
associated survival craft
craft forming part of and used in conjunction with a marine evacuation system (3.5) and which are not
directly accessible via the passage (3.7)
3.4
handling of associated survival craft
deployment, retrieval, inflation, mooring, and other actions necessary to prepare the survival craft (3.9)
for boarding
3.5
marine evacuation system
MES
appliance for the rapid transfer of persons from the embarkation deck of a ship to a floating platform
(3.8) or survival craft (3.9) by means of a passage (3.7)
3.6
MES crew
personnel required for the safe operation of the MES (3.5)
Note 1 to entry: These personnel may include the person in overall charge at the evacuation station, platform
crew and others as needed.
3.7
passage
integral component of a marine evacuation system (3.5) to provide safe descent of persons from the
embarkation station to the floating platform (3.8) or survival craft (3.9)
Note 1 to entry: The passage can be an inflatable or rigid slide, a vertical passage or any other arrangement
providing the same function.
3.8
floating platform
inflatable structure which may be fitted to the bottom of the passage (3.7) to hold evacuees awaiting
entry to survival craft (3.9)
Note 1 to entry: In some system configurations, a survival craft may also serve as a floating platform.
3.9
survival craft
craft capable of sustaining the lives of persons in distress from the time of abandoning the ship
3.10
survival craft unit
multiple pre-connected survival craft (3.9) deployed together
3.11
system capacity
total number of evacuees which can be evacuated by a given MES (3.5) within the available evacuation
time (3.1)
4 Test arrangement
4.1 Test rig
As an alternative to testing from a floating ship, a test rig which deploys the MES over water may be
used for the determination of MES capacity.
4.2 Position of the test rig
The side of the test rig, simulating a ship’s side, shall be parallel to, and in line with, the outer boundary
of the pier.
4.3 Installation height of MES
The entrance to the passage shall be positioned at 15 m (±1 m) above the waterline or at least at the
height for which the system is to be approved if this is less than 15 m (±1 m) above the waterline.

4.4 MES/ship interface
The MES retaining and connection lines of the test rig shall be arranged and fitted as on a real ship with
the same installation height and longitudinal distances as used for the capacity test.
4.5 Associated survival craft
If the capacity test includes the use of associated survival crafts, these shall be positioned on the pier at
a distance of at least 15 m from the centreline of the access entrance to the MES passage.
If more than one associated survival craft is used with the system, at least two of the largest associated
survival crafts necessary to attain the maximum capacity of the system shall be deployed and handled
during the test.
4.6 Access to embarkation area
The test rig should have a dedicated assembl
