Introduction
Successful safety and environmental protection during the recovery of hydrocarbon resources requires a
structured approach to be applied to the identification and assessment of the hazards present during the
various phases in the lifecycle of an offshore installation. These principles also apply to the development
of emergency response strategy, emergency response measures and procedures. Understanding of the
[6]
hazards can be achieved by application of ISO 17776, which gives guidelines for hazard identification and
assessment for offshore installations.
The content in this document on escape, refuge, evacuation, recovery and rescue is consistent with the
[4]
content of ISO 13702 but addresses in more detail how these aspects are built into development of
emergency response measures.
This document has been prepared primarily to assist in the development of new installations. Retrospective
application of this document is only relevant where it is reasonable to do so. During the planning of a major
change to an installation there can be more opportunities to implement the requirements, and a review of
this document enables identification of clauses which can be practically utilized in the change.
This document is based on an approach where the selection of measures for emergency response is
determined by an evaluation of hazards on the offshore installation. The methodologies employed in this
assessment and the resultant recommendations differ depending on the complexity of the production
process and facilities, type of facility (i.e. open or enclosed), number of POB, and the environmental
conditions associated with the location of operation.
The principal objectives of this document are to describe both the approach to be used and important
considerations in determining the emergency response measures that are required on an offshore
installation to:
a) protect people;
b) minimize impact on the environment;
c) minimize impact on assets and operations.
The requirements in Clauses 6 to 15 are arranged as follows.
— Objectives identify the goals to be achieved by the emergency response measures being described.
— Functional requirements and guidelines represent the minimum conditions to meet the stated objectives.
The functional requirements are performance-orientated measures and, as such, are applicable to the variety
of offshore installations utilized for the development of hydrocarbon resources throughout the world.
— The provisions describe recognized practices for consideration in developing the measures for emergency
response.
— Functional requirements are supplemented by guidelines in developing the measures for emergency
response in Annexes A to F. The guidelines and annexes are intended for use in conjunction with
requirements, industry standards and individual company philosophy, to determine the measures that
are necessary for emergency response.

Requirements and guidelines for emergency response
1 Scope
This document specifies objectives, functional requirements and guidelines for emergency response (ER)
measures on installations used for the development of offshore hydrocarbon resources. It is applicable to:
— fixed offshore structures;
— floating systems for production, storage and off-loading.
NOTE For mobile offshore units, the ER plans developed in conformance with the requirements and
recommendations of the International Maritime Organization (IMO) are generally adequate for the normal,
independent operation of the unit in most locations. The following aspects of ER planning are not generally addressed
by IMO and are topics intended for inclusion in the scope of this document where relevant to the specific installation:
— area evacuation, e.g. precautionary evacuation in areas of tropical revolving storms;
— combined operations (where an integrated command and ER system is relevant);
— arctic operations;
— uncontrolled flow from a well.

5 Objectives
Effective management systems are required to address the health and safety aspects of the activities
undertaken by all companies associated with the offshore recovery of hydrocarbons. These management
systems are applied to each stage in the life cycle of an installation and to all related activities. Such a
[2]
management system, which has been developed for environmental issues, is described in ISO 14001 and
the principles contained therein can also be applied to issues relating to health and safety.
EXAMPLE Operators are expected to have an effective management system. Contractors are expected to have
either their own management system or conduct their activities consistently with the operator’s management system.
One key element of effective management systems is a systematic process of identification of hazards,
followed by evaluation and risk management. Risk reduction is an important component of risk management,
and the selection of risk reduction measures predominantly entails the use of sound engineering judgement.
However, such judgements are supplemented by recognition of the particular circumstances, which can
require variation to past practices and previously applied codes and standards. In certain circumstances,
risk assessment can provide useful input to the decision-making process provided that the operator has
established criteria for this purpose. Risk reduction measures include those to prevent incidents (i.e.
reducing the probability of occurrence), to control incidents (i.e. limiting the extent and duration of a
hazardous event) and to mitigate the effects (i.e. reducing the consequences). Preventative measures such as

ISO 15544:2024(en)
using inherently safer designs and ensuring asset integrity are emphasized wherever practicable. Measures
to recover from incidents are provided based on the evaluation, and developed considering possible failures
of the control and mitigation measures. Based on the results of the evaluation, detailed health, safety and
environmental objectives and functional requirements are set at appropriate levels.
This document sets out an approach to treat ER in the same systematic manner.
ER measures shall be provided based on an evaluation that takes into account possible failures of the control
and mitigation measures. It is these ER measures, which, as an integrated system, provide the appropriate
response to an incident occurring on or near the installation.
The results of the evaluation process and the decisions taken with respect to the need for, and role of, any
measures required for ER are recorded in the emergency response strategy, see Clause 6.
[4]
ISO 13702 introduces the concept of strategies but states that such strategies do not have to be separately
documented, as the relevant information can be included with other HSE information for an installation
or can be contained in recognized codes and standards that are relevant to the operating location. Indeed,
there can be significant overlap between strategies and other HSE information, so that combining this
information into one source is likely to assist the understanding of the people on the installation of how the
various measures are integrated.
The ERP shall be developed to set out the operational and procedural requirements to be follow under the
various emergency scenarios that are relevant for a particular installation.
The resources that typically are involved in ER can be divided into three categories:
a) Installation resources
Resources which are under the direction of the person in overall charge of the installation, and which
are immediately available. They include personnel and equipment, vessels and helicopters that have
been assigned ER duties.
b) Area resources
Resources which are not under the direction of the person in overall charge of the installation, but
which are located in the same area. The resources are made available by a mutual aid or cooperation
agreement, and can include installations in the vicinity, supply vessels, other vessels and helicopters.
c) External resources
Resources which are not under the direction of the person in overall charge of the installation, and
which are not located in the area. Such resources can be the organization and resources of national and
international rescue services, as well as other resources who professional bodies or others can place at
the disposal of the field or installation manager. These resources can include aircraft, helicopters, coast
guard and navy vessels, shore-based personnel resources, regional or national oil pollution resources,
the public health service and resources governed by international agreements and other agreements
among the operators of installations.
6 Emergency response strategy
6.1 Objectives
The objectives are to identify and record the intended approach for ER, including the underlying risk
evaluation.
6.2 Functional requirements and guidelines
An emergency response strategy (ERS) shall be developed for offshore installations based on an assessment
of the potential emergencies that can arise.

ISO 15544:2024(en)
The ERS shall:
— address the issues of organization, procedures, equipment, information, training and the role of other
measures that are necessary to achieve a successful ER;
— identify ER measures;
— set out performance requirements for each ER measure consistent with its role specified in the ERS;
— set out how ERS performance requirements are measured and verified;
EXAMPLE The time to muster is an example of a performance requirement.
— account for how an emergency could escalate as the situation progresses;
— account for reliability and availability of ER equipment to determine whether additional components are
required to deal with periods of non-availability, e.g. due to maintenance or breakdown;
— account for survivability of ER equipment under emergency conditions;
— account for availability of ER measures during an emergency; and
— account for the potential unavailability of personnel with key ER roles in an emergency.
NOTE 1 The ERS is subject to local regulations, as applicable.
The ERS shall be:
— periodically re-evaluated;
— updated whenever there is a change in risk which affects the content of the strategy; and
— subject to ongoing improvement by learning from incidents, accidents, exercises and drills.
Emergency planning should include sufficient flexibility to remain effective given the uncertainties in how
an emergency could develop. Emergency communication arrangements shall inform relevant personnel of
their required actions.
For new installations the development of the ERS, and the associated emergency response measures, should
be an integral part of the design process.
The results of the evaluation process and the decisions taken about the need for, and role of, the emergency
response measures shall be recorded in the ERS. This record shall be made available to those who operate
the installation and to those involved in subsequent change to the installation.
Key assumptions used in the development of the ERS shall be recorded, so that they can be reviewed to
confirm that they are still valid.
The ERS shall be periodically reviewed by the owner of the strategy.
ER measures to deal with acute oil pollution shall be integrated into the overall ERP. The company
responsible for an offshore installation shall liaise with relevant authorities to develop plans to deal with
environmental incidents identified in the ERS.
When developing the ERS, the maximum number of people who might be involved in an emergency shall
be evaluated and documented. During some phases of life cycle of an installation, such as during major
construction work, the number of people on the installation can be significantly higher than assumed in the
ERS. Prior to such phases of work, the impact on ER shall be evaluated so that changes to the ER measures
can be implemented before number of people increases.
Further guidelines on strategies are given in Annex A.

ISO 15544:2024(en)
7 Emergency response plan
7.1 Objective
The objective is to provide a statement of the key ER actions expected under emergency conditions and the
information required to support those actions.
7.2 Functional requirements and guidelines
An emergency response plan (ERP) shall be developed that:
— covers each stage of an ER, from identification of the emergency until the emergency is over;
— addresses the full range of emergencies identified in the ERS;
— addresses the operational and procedural requirements for persons that have a role in responding to an
emergency;
— specifies individuals’ roles and responsibilities for the emergency response;
— addresses the transfer of emergency roles in the event of an individual becoming unavailable (e.g. due to
injury in the initial incident);
— accounts for the range of potential weather conditions;
— accounts for human factors (see B.1.4); and
— describes alarm signals used on the installation, as well as their meaning and required actions.
The ERP shall also cover other groups who provide services in the event of an emergency, but who are not
themselves directly involved in the installation operations. Those groups shall be consulted during the
development of the ERP.
The presence of another installation alongside (e.g. during workovers or where a flotel is brought alongside)
can impair certain options for evacuation or escape, but can also provide other options via the other
installation, for example, if a bridge link is established. Where installations are involved in combined
operations:
— ERP for both installations shall be reviewed and, if necessary, revised;
— combined ERP or a bridging document shall be agreed prior to commencing operations, and the
arrangements of both installations modified accordingly;
— command structure for the combined operations shall be established to specify the respective emergency
command responsibilities.
In preparing the ERP, the various emergency scenarios requiring a response shall be evaluated and the
appropriate organization to deal with these scenarios put in place. To avoid excessive detail and repetition,
for the purposes of planning, emergencies may be grouped into generic types.
A competent person shall be appointed who is responsible for maintaining the effectiveness of the ERP and
for including lessons learnt from the use of the ERP in drills, exercises or actual emergencies.
Locations at which the ERP is used in an emergency shall be identified and copies be made available.
The ERP shall be revised to reflect changes in operation, plant and equipment or personnel.
Arrangements shall be provided to enable persons involved with installation operations to submit ERP
improvement opportunities for evaluation.
To enable an effective and comprehensive ERP, the following factors are relevant in preparing the plan:
— identified responsibilities for decision-making;

ISO 15544:2024(en)
