2 General information
2.1 Purpose of the Damage Control Booklet
The Booklet serves the purpose to give the master and the crew guidance in the case of damage. By
the instructions given herein the crew shall be capable of assessing the situation and determining the
necessary actions to be taken in order to minimize consequences of the damage with respect to safety
of persons on board and protection of the marine environment.
Generally, the master should exercise prudence and good seamanship when taking the necessary
actions.
2.2 Responsible persons
The responsibilities are as follows (to be identified by rank, to be filled in by the owner or master of
the vessel):
Overall responsibility:
Initiation of necessary actions:
Determination of extent of damage:
Pumping operations:
Evaluation of damage scenario with the loading computer:
Information to external parties
2.3 Immediate action after casualty
It is to be assessed by the master whether the damage case will lead to immediate capsizing or sinking
of the ship. For this assessment the present weather and sea conditions shall be considered. In case
the situation is judged as very critical and the ship is in immediate danger of capsizing or sinking the
ship has to be abandoned at once.
Otherwise personnel not working for the ship s safety shall be ordered to stay at the rescue boat. All
persons are ordered to wear life vests and / or survival suits if available.

4.2 Actions to be taken in case of damage
The following actions are to be taken immediately after damage in order to ensure the watertight
integrity and to assess the severity of damage.
4.2.1 Closing of watertight doors and hatches
All watertight doors and hatches are to be closed immediately!
In general the status of watertight doors and hatches is closed (refer to list of watertight openings given
above). This status can be checked on the status panel on the bridge. Additionally a visual check by a
designated person shall be performed ensuring the tightness of these doors/hatches. Prior to sending a
crew member to such an inspection route, it is to be justified that the personal risk for this person is
within acceptable limits.
In case it is deemed absolutely necessary to open a watertight door/hatch again in the damaged
condition in order to proceed with further actions, it should be carefully judged whether this door is
crucial to prevent progressive flooding. After use the door/hatch is to be closed immediately.
4.2.2 Closing of weathertight openings
All weathertight doors and hatches are to be closed immediately. Furthermore the closing appliances for
ventilation openings are to be secured.
4.2.3 Closing of valves
All vales in the piping system are to be closed immediately as far as the connected pipes are not used
for pumping operations.
4.2.4 Check of the extent of damage
If possible, a visual check of the extent of damage and the included compartments shall be carried out.
4.2.5 Sounding of flooded compartments
After having found out which compartments are damaged, the amount of inflooded water shall be
determined by sounding measurements. In case a compartment is connected to the remote sounding
system the amount of inflooded water can be determined directly.
4.2.6 Draft readings
Draft measurements at the draft marks shall be performed. Additionally the heeling angle shall be noted.
4.2.7 Calculation of inflooded water
By a periodical measurement of the sounding for damaged compartments and comparison with the draft
readings a calculation of the inflooding water per time (flooding rate) can be made.

Model Booklet for Container Vessels - Damage Control Booklet
4.2.8 Use of pumps
Two (2) pumps in the water ballast system and bilge system are available for pumping out water from
compartments which have been damaged.
Two scenarios may arise:
The amount of inflooding water exceeds the capacity of the available pumps. In this case the
compartment must be isolated by closing all watertight accesses (including vales in the piping
system). The use of pumps is only partly useful,
The pump capacity exceeds the rate of inflooded water therefore the pumping shall be continued
permanently.
The pumps shall be held in a permanent stand-by modus and ready for service at any time.
4.2.9 Use of Loading Computer
For determining possible scenarios of liquid transfer operations, the loading computer might be used
(refer to Chap. 5). Restrictions of the ability of the Loading Computer are to be considered.
4.2.10 Liquid transfer operations
Before any filling or discharging of water ballast is carried out a thorough check and pre-calculation of
the resulting floating position is to be carried out and the limit values for stability and longitudinal
strength are to be checked.
The crew must be aware that filling or discharging of water ballast tanks can have negative influences
on the stability due to the effect of free surfaces for partially filled tanks!
For this reason it is strongly recommended before liquid transfer operations will take place that the
possible negative effects of such operations are assessed by pre-calculation (e.g. by land based
consultancies).
In order to minimise the heel and trim of the vessel it may be advisable that water should be pumped in
the tanks opposite to the damage location. If possible, the filling of slack tanks should be preferred to
improve the stability behaviour of the vessel.
4.2.11 Determination of the ground condition (in case of grounding only)
In case the vessel is run aground a check of the ground condition and the extent of damage can be
performed by a diver. This check shall only be performed with the necessary safety measures when the
ship is in a stable position and no movement on the ground is anticipated.
4.2.12 Information to owner, coast guard and consultancy services
The local coast guard and the owner of the vessel shall be informed about the present situation. A
possible outflow of oil should be stated immediately.
In general all information about damage extent, floating position and loading condition prior to damage
shall be forwarded to consultancy services in order to get support in determining the severity of the
damage and to determine the necessary actions to be taken.

Model Booklet for Container Vessels - Damage Control Booklet
5 Use of Stability Computer
The use of a Loading Computer for an estimation of the stability after damage is very restricted as
common loading instruments are not able to calculate damage stability in a correct way. - Any
calculation which has been carried out with a normal Loading Computer intended for intact calculation
should be regarded as a very rough estimation only. Such results should be treated with utmost caution!
In case the loading instrument is capable of calculating damage stability, the exact loading condition
prior to the accident and the actual extent of damage shall be considered.
6 Summary of damage stability calculation
6.1 Applicable regulation
The vessel complies with the requirements as laid down in SOLAS II-1. This damage stability regulation
is based on a probabilistic concept which means that the probabilities of possible damages are
considered acc. to standardised formulas. The survivability of the vessel assumed damaged with these
possible damages is assessed. The combination of probability and resulting survivability leads to a
certain contribution to a attained index A which has to be greater than the required index R (A>R).
This kind of damage stability analysis is based on several assumptions (e.g. permeability of rooms,
considered initial drafts and GMs). The calculated results according to the regulations can differ
significantly from results of real damages of an actual loading condition.
6.2 Damage stability criteria
If all of the following criteria are met, a damage case gives full contribution to the attained index A:
Final heeling angel d" 25 deg.
Maximum value of the righting lever curve e" 0.12 m
Range of the righting lever curve e" 16 deg.
No immersion of opening points
If the floating position is more critical, a smaller contribution is considered.
6.3 Special remarks
Acc. to SOLAS II-1 no additional heeling moments (e.g. wind), no wave action and no longitudinal
strength limitations were considered in the damage stability calculation.

7 Sample damage cases
In the following, the floating position and the GZ-curve of the vessel as well as the critical openings are
shown for selected damage cases.
CAUTION: As below listed damage results are taken from the approved damage stability
calculation, they are based on several assumptions (e.g. permeability of rooms, considered
initial drafts and GMs). The calculated results can differ significantly from results of real
damages of an actual loading condition.
Model booklet treatment note:
The following sample cases should be shown:
" each of the three drafts acc. SOLAS
" one damage per cargo hold compartment and one damage for engine room
" full transverse and vertical penetration (e.g. damage 4.0.0*, not damage 4.1.0*), even if s=0
" if s=0 for full transverse and vertical penetration (e.g. 4.0.0*), a damage with reduced
transverse and / or vertical penetration could be shown additionally (e.g. 4.1.0*)
* Nomenclature of certain software, other nomenclature may differ
