10 CONTINGENCYPLANNING
10.1 Introduction
The primary objective of contingency planning is to ensure the safety of Project personnel and the public
and to protect the environment. Other important objectives are the protection from loss of the financial
investment, investigation of the incident,and restoration of business continuity in the aftermath of an
emergency.
Specifically, EnCana’s principles to effectively manage incidents are as follows:
 protect human life, (workers, responders, public);
 effectively rescue and treat casualties;
 minimize environmental impacts;
 minimize damage to company, public and private property;
 effectively use the combined resources of EnCana, mutual aid partners, the government and other
external services;
 provide factual information to news media and other stakeholders on a timely basis;
 preserve records and evidence for use in post incident investigations; and
 protect shareholder value.
The Deep Panuke Emergency Management Plan (DPEMP) will replace Alert/Emergency Response
Contingency Plan (AERCP), which has been used for the Cohasset Project and EnCana’s other East
Coast offshore activities. The DPEMP will provide emergency response command and control
functions for both onshore and offshore emergency situations and will cover foreseeable emergencies
during all phases of the Deep Panuke Project.The DPEMP will take into account hazard identification
and assessment, environmental considerations, consultation with government agencies, incorporation of
industry best practice,and use of external support resources.
As a requirement of the EnCana EHS Best Practices Management System, the DPEMP will align with
the corporate standard for emergency response plans with respect to the incident command structure and
incident classification terminology.It will also conform to the CAPP “Guidelines for the Preparation of
Emergency Response Plans”,Canadian Standards Association (CSA) standard CAN/CSA-Z731
“Emergency Planning for Industry”,and the Joint Rescue Coordination Centre (JRCC) “Search and
Rescue Protocol for the Oil and Gas Industry”.
The DPEMP will tie in three levels of operations:field, business unit,and corporate office, to ensure
effective forward planning, communications and an effective overall response strategy. A copy of the
Deep Panuke Volume 2 (Development Plan) November 2006 10-2
DPEMP will be filed with the CNSOPB and other relevant regulatory agencies prior to commencing
operations.
The DPEMP will define the call-out procedures for the EnCana Incident Command Team, support
resources, liaison with government agencies, communications with the corporate organization, media
response, and communication with next of kin and relatives.
The MOPU and support vessels will have site-specific emergency response plans complying with
regulatory requirements. These plans will ensure the effective mobilization of personnel, facilities, and
onsite resources in the event of an on-site accident or incident. They will provide information on the
incident type and severity, notification and mustering protocol, incident command team structure and
key duties, response and evacuation procedures,communication protocol, and supporting forms and
checklists.
Procedures will be developed to bridge the DPEMP and contractors’ emergency response plans, when
necessary,to ensure a coordinated response during an emergency.
EnCana’s emergency preparedness process also involves all aspects of planning, training, exercising,
response,and quality assurance. The DPEMP may be amended,as required,as the project progresses
through the construction, drilling, operation, decommissioning,and abandonment phases of its lifecycle.
Figure 10.1 identifies the key components of EnCana’s Emergency Preparedness.
10.2 Deep Panuke Emergency Management Plan
The DPEMP will outline the measures to effectively prepare for and respond to foreseeable emergency
situations involving operations, equipment and products. The DPEMP will cover the following three
broad areas of emergency management responsibility:
 provision of logistical, consultative advice and support to the field Incident Commander. Incident
Commander is an incident command system terminology for the “person in charge” of on-scene
response, for example, the Offshore Installation Manager, Vessel Master, or Helicopter Pilot;
 assessment of short and long term risks and impact of the emergency, and co-ordination of
regulatory liaison, media communications and relative response; and
 appropriate notification of and communication with the EnCana Crisis Management Team.
Deep Panuke Volume 2 (Development Plan) November 2006 10-3
Figure 10.1 EnCana’s Emergency Preparedness
The DPEMP will address or include the following:
 plan administration;
 incident command organization, roles and responsibilities;
 notification and communication protocol;
 emergency response actions based on incident severity classification;
 risk assessment criteria for developing incident action plans;
 emergency response procedures for serious injury/death, including medical evacuation, loss of well
or process control, fire/explosion, overdue/lost craft, collision avoidance, diving emergency, spill
incident, severe weather, and security incident/threat of criminal activity;
 JRCC liaison;
 support resources;
 media, next-of-kin and relative response procedures;
 business restoration/resumption planning;
 training requirements;
Deep Panuke Volume 2 (Development Plan) November 2006 10-4
 supporting documentation including manuals, forms, checklists and information appendices, and
 auditing and continuous evaluation.
Additional information on specific emergencies that could occur during offshore activities is outlined as
follows.
10.2.1 Loss of Well Control (Drilling & Well Servicing)
All plans and equipment necessary for the establishment and maintenance of well control will be
completed and provided for offshore drilling operations, in compliance with CNSOPB requirements.
Procedures and equipment for well control, and early kick detection are covered by the “EnCana Well
Control Procedures Manual” and the “EnCana Drilling Policies and Guidelines Manual” which will be
updated for the Deep Panuke Project. This will include, but is not limited to, shallow gas, lost
circulation, kicks and underground flows.
During workover and completion operations, a minimum two-barrier well control philosophy will be
strictly adhered to. This ensures redundancy for well control against all predictable occurrences. This
will include combinations of kill fluid, downhole plugs, blowout preventers,and wellhead safety valves.
The MOPU contractor’s safety procedures for loss of process control will be reviewed to ensure
compliance with CNSOPB regulations and the Deep Panuke project’s safety design philosophy.
10.2.2 Subsea Pipeline Loss of Containment
Contingency procedures for loss of containment of the subsea pipeline will be included in the MOPU
operations procedures manuals and supporting documentation. The mitigation measures will include the
following:
 isolation procedures for ruptured flowlines (including closing SSSV), which include securing the
area and notifying vessels in the vicinity;
 containment and clean up of spilled hydrocarbons using on-site and/or specialized third-party
sourced equipment;
 repair procedures including mobilization of necessary equipment and services;
 inspection procedures for assessing the damage, adequacy of repairs and restart of operations;
 compensation considerations for damage to third party caused by pipeline incidents; and
 documentation to report and monitor spills, and to meet regulatory requirements.

10.2.3 Platform Incidents
Contingency procedures for incidents on the MOPU will be included in the MOPU Emergency
Response Plan and its supporting documentation as noted previously. These incidents include
injury/illness/death to personnel from operational or environmental hazards, structural failure resulting
from environmental or operational forces, loss of containment, hydrogen sulfide release, fire/explosion,
severe weather (storm winds and/or waves, ice accretion/impact), man overboard, manned diving
emergency, and abandon platform.
10.2.4 Collision
To a large extent, fixed installations in the open sea rely on the skill and vigilance of mariners to avoid
collision. Vessels approaching the installation must be detected and the potential threat to the
installation assessed as early as possible. This is in order to initiate timely action and to advise the
approaching vessel of the situation.
The collision hazard will be addressed by establishing a Safety Zone rising above the sea surface around
the MOPU and potentially the subsea facilities, augmented by EnCana’s existing collision-avoidance
procedures. The Safety Zone, MOPU, infield flowlines, umbilicals, subsea equipment, hot tap location
(SOEP Option) and export pipeline,including point of landfall (for M&NP Option) will be identified in
nautical charts published by the Canadian Hydrographic Service and in the Notice to Mariners issued by
the Canadian Coast Guard.
The premise for establishing the Safety Zone will be based on a risk assessment, regulatory
requirements, fisheries considerations,and EnCana East Coast Collision Avoidance procedures. The
procedures provide for the establishment of a “Collision Zone” 500 yards (~500m) around the
installations and a “Near Miss” zone, having as its inner boundary the perimeter of the Collision Zone
(500 m) and its outer boundary at 2.0 nautical miles from the installation.In addition, contacts with
vessels with an estimated closest point of approach of between 2 and 5 nautical miles will be tracked and
reported to the installation if radio contact cannot be established.
A dedicated 24-hour standby vessel will monitor potential incursions near and into the Safety Zone and
will make the necessary interventions if required.
Active and passive navigational aids,such as radar transponders, fog horns,and lights,will be installed
on the MOPU and other surface facilities. In addition, anti-collision radar will be operated on the
MOPU and standby vessel. This will provide early warning of a potential collision hazard to personnel
on the MOPU and offshore support vessels, and allow for the straying vessel to be warned and diverted.
If the vessel cannot be diverted prior to collision,the production and/or drilling installations will be
Deep Panuke Volume 2 (Development Plan) November 2006 10-6
secured and personnel evacuated promptly. The operations and emergency procedures will address this
kind of contingency.
10.2.5 Marine Incidents
Guidelines for the safe operation of vessels chartered by EnCana are addressed by the “EnCana
Standby/Supply Vessels Operating Manual”. Vessels chartered by EnCana will be certified by
Transport Canada, insured, and will meet applicable regulatory requirements with respect to safe
manning, emergency response equipment, plans and procedures,and crew emergency response training.
EnCana will review the marine procedures manuals of chartered vessels and inconsistencies identified
through this review will be addressed by way of bridging documents. A vessel tracking procedure will
be implemented to stay updated on the vessel’s position and mode of operations round the clock.If
vessels are sub-contracted by contractors, the safety procedures to be followed will be bridged to
EnCana’s requirements.
10.2.6 Aviation Incidents
Project facilities will be designed to minimize the number of personnel involved in the operation of the
offshore manned facilities to reduce the transportation risk to workers.EnCana will use Transport
Canada-licensed helicopter contractors with eastern Canadian offshore flying experience, experienced
pilots and ground staff. Installation helidecks will be designed to ensure that they comply with
Transport Canada (Aviation Safety) regulations and the helicopter contractor’s standards.Flight-
following procedures will be implemented to track helicopter movements. A standby vessel will stay in
close proximity to the MOPU during helicopter arrivals and departures.Pre-acceptance and routine
audits of the helicopter contractor’s maintenance, safety and operational documentation will be
performed by EnCana.
A bridging document will be prepared to ensure that the MOPU helideck safety procedures are bridged
with that of the aviation contractor. Alternatively, EnCana may elect to adopt the helicopter contractor’s
practices and procedures. Periodic exercises simulating crash landings on the facilities will be
conducted and these exercises may involve personnel on the platform, standby and supply boats, other
marine vessels and the helicopter contractor. The JRCC and government agencies,such as the CNSOPB
and Transport Canada will be requested to participate in these exercises,when appropriate and available.
Personnel using helicopter transportation will receive training on how to react in the event of a
helicopter accident, including escape and egress underwater.The use of helicopter survival suits and
emergency breathing apparatus will be made a compulsory requirement for all passengers.

10.2.7 Fire / Explosion
The Deep Panuke Emergency Management Plan will address all levels of fires and explosions including
the following:
 small fires in a non-critical area of a facility;
 fires that can be controlled with on-site personnel and equipment; and
 fires that are out of control and have the potential to cause major equipment loss, release of an
explosive mixture, unconfined vapor cloud expansion or boiling liquid expanding vapor explosion.
For onshore fire incidents, site specific procedures will be developed to deal with the situation and to
protect nearby residential or commercial premises and the general public.
10.2.8 Hydrogen Sulphide (H
2
S) Release
A H
2
S Contingency Plan conforming to API RP 55 ‘Recommended Practices for Oil and Gas Producing
and Gas Processing Plant Operations Involving Hydrogen Sulfide’ will be developed for the MOPU.
The purpose of this plan is to ensure that the consequences of an escape of hydrogen sulphide are
known, and that the preventive and mitigative actions are documented. Contracted drilling rigs will be
required to have and implement H
2
S contingency plans conforming to API RP 49 ‘Recommended
Practice for Drilling and Well Servicing Operations Involving Hydrogen Sulfide’.
The H
2
S Contingency Plan will be communicated to the Project team,including contractors,and regular
drills and exercises will be conducted to ensure a high state of alert and response preparedness.The
plan will include information on potential hydrogen sulphide release sources on the installation,
detection and alarm systems, and control measures to be taken in the event of a release.A positively-
pressurized temporary refuge will be established on the MOPU and a breathing air system will be
installed on board.
In-field flowlines containing H
2
S will be identified in nautical charts and may be included within the
Project Safety Zone. Offshore support vessels will be equipped with H
2
S detectors and respiratory
protective equipment. H
2
S training will be mandatory for all personnel traveling to or working in the
field once operations commence.

10.2.9 Spills
The DPEMP will contain specific information on how EnCana will respond to spills or pipeline loss of
containment and will be supplemented by the Deep Panuke Spill Response Plan and EPP. Please refer
to Section 9 for details.
10.3 Accountability
A key component of the DPEMP is the accountability of personnel and their roles within the emergency
response management system. These accountabilities are at all levels of the organization and specify
various actions prior to, during,and after a response.
Senior management is accountable for endorsing the DPEMP and will ensure that the necessary
resources are allocated to support its implementation.Field supervisors are expected to ensure that the
system is properly implemented at the worksite and that an appropriate response is carried out. Each
employee’s responsibility is to ensure that they report emergencies immediately and conduct the on-site
emergency response in compliance with their experience and training.
10.4 Training
All training records will be maintained throughout the Project team member’s tenure with EnCana.
Emergency response training requirements stipulated in the CAPP East Coast Offshore Training and
Qualifications Practice will be followed for the duration of the Project. EnCana will support the Project
team, including contractors,in achieving the highest levels of competency with regard to emergency
response preparedness.
10.5 Drills and Exercises
10.5.1 Purpose of Exercising
Conducting emergency exercises allows EnCana to validate and improve response capability without
actually going through real-life incidents.While meeting the needs and requirements of external parties,
the internal benefits of exercising include the following:
 enhances emergency response capability;
 improves co-ordination and proficiency of tasks;
 identifies areas in need of program improvements;
 identifies resource requirements in terms of staffing, equipment, logistics or procedures;
Deep Panuke Volume 2 (Development Plan) November 2006 10-9
 validates existing plans and procedures; and
 meets regulatory requirements.
10.5.2 Philosophy of Exercising
EnCana’s overall philosophy to emergency response exercising is based upon the following principles:
1.Validate vs. Test – A test tends to imply a pass/fail relationship or the possibility of performing
poorly.EnCana conducts exercises in order to identify areas for improvement, rather than to
indicate a failure to perform.
2.Training - EnCana’s second principle of emergency response exercising is that it should always
provide positive learning opportunities and enable participants to demonstrate the use of skills
and knowledge. Successful exercises and simulations maximize learning opportunities by
developing an action plan to capitalize on the lessons learned and areas for improvement. This
leads to a cycle of continuous improvement that extends beyond the participants or the individual
business unit.
3.Mix of Exercise Activities - Utilizing a mix of exercise activities ensures an adequate level of
capability is maintained, while ensuring the program is cost-effective. Exercise activities range
from single function drill or table top discussion, to a complex full-scale exercise involving
internal and external personnel.
4.Exercise Scheduling - Exercising should be scheduled and part of the overall emergency
preparedness process.
