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.

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 assembly area. However, other arrangements are acceptable if
access by the evacuees to the embarkation point, in a safe and constant flow, is ensured.
5 Test persons
5.1 Number of test persons
5.1.1 The number of persons to be selected for the test shall correspond to at least 110 % of the
capacity of the largest survival craft used with the MES, except as specified in 5.1.4.
5.1.2 In the case where a survival craft unit or units are used, a number of test persons corresponding
to 110 % of the largest individual survival craft shall be used, except as specified in 5.1.4.
5.1.3 In the case where only a single survival craft is used, of which the capacity is less than 165
persons, a number of test persons corresponding to 100 % of the survival craft shall be used.
5.1.4 If the survival craft capacity is larger than 165 persons, only 165 test persons shall be used and
the test shall be conducted under the conditions described in 6.8.
5.2 Selection of test persons
5.2.1 Subjects shall

Weight range, kg

10 %–20 % 60 %–80 % 10 %–20 %
6 Test procedure
6.1 The test persons, wearing approved lifejackets conforming to the requirements of the LSA Code,
shall be lined up in the embarkation area, if space permits, or on the stairway leading to the embarkation
area in a way that there shall not be any interruption in the flow of the test persons.
6.2 Prior to initiating the test, the MES crew shall be ready in the embarkation area and awaiting the
order to deploy the system.
6.3 When the order to initiate the test is given, the timing is started and the system is activated by the
MES crew.
6.4 When the floating platform or the survival craft at the base of the passage is ready for boarding and
the access passable, the designated MES crew descends the MES and prepares to receive the test persons.
6.5 For safety reasons, the timing may be temporarily interrupted at this point while the test
persons assemble in the embarkation area and shall be resumed when the test persons are lined up as
described in 6.1.
6.6 If the MES consists of more than one passage, they shall be used equally.
6.7 When the all-clear signal is given, the test persons descend to the floating platform/survival craft
and transfer to the survival craft which is designated as the first to be disengaged from the system.
6.8 If either a single survival craft or survival craft unit is used as described in 5.1.4, the following
procedure is used as equivalent to verify operational capabilities in a crowded survival craft.
6.8.1 If a single survival craft is used, the test persons shall assemble in the area closest to the end
of the passage closest to vessel connection points to simulate that the operating area for the crew is
crowded.
6.8.2 If a survival craft unit is used, the test persons shall assemble in the craft(s) closest to the end of
the passage(s) and in such a way that at least one craft is occupied to its full capacity.
6.9 The handling of associated survival craft may be carried out in parallel with the descent of the test
persons, provided that the MES crew is available to perform all operations safely.
6.10 When the last survival craft to be used for the test is disengaged, the time is stopped.
7 Test timing
7.1 Timekeepers
7.1.1 The role of the timekeeper(s) shall include, but is not limited to, the following:
a) ensuring all stopwatches to be used to record event timings are synchronized;

---------------------- Page: 9 ----------------------
ISO 16707:2016(E)

b) ensuring all timed operations to be recorded can be viewed;
c) ensuring that if there is more than one timekeeper, each time keeper is aware of their individual task;
d) recording of test times as detailed in Table 2;
e) recording the capacity of the floating platform/primary raft(s) as applicable;
f) recording the capacity and boarding sequence of associated survival craft as applicable;
g) recording the number of MES crew used during the test and the positions of MES crew as relevant.
7.1.2 The use of video cameras appropriately synchronized can be used to assist in recording the
timing of the key events of the evacuation, if necessary.
7.2 Sequences to be timed
7.2.1 Prior to the initiation of the test, all stopwatches shall be synchronized and set to 0:00. When the
signal to initiate the test is given, the timekeepers shall start their stopwatch(s). The timekeeper(s) shall
record the time at which each of the events indicated in Table 2 occur. The time recorded shall be the
time shown on the stop watch when the event occurs.
7.2.2 Depending on the design of the MES, and the number of
