5. Scope

MODES shall apply to all offshore and onshore facilities, including all hydrocarbon production facilities, subsea systems, structures, utility systems, pipelines, accommodation facilities, and marine systems.

The scope of MODES is: a) All areas of facilities design. b) Assess, select, define and execute stages of a project. c) Design of new facilities as well as design modifications for existing facilities. d) A reference point for existing facilities. Where deficiencies are found compared to the

MODES, industry practice and permitted safety levels, etc., then the improvements shall comply with MODES, where this is practical or relevant. Where compliance with MODES is not practical, alternative solutions meeting the objectives shall be sought.

e) The basis for facility design assumptions for evaluation of exploration and new business prospects to ensure that screening concepts and costing, etc. comply with Maersk Oil design requirements.

5.1 Existing Facilities

5.1.1 Audit / Gap Analysis

This standard is not retroactive, although it shall apply to extensions of existing installations unless the application of the MODES is not compatible with the existing design.

5.2 Leased Facilities

For leased facilities e.g. an FPSO owned and operated for Company by a specialist FPSO Contractor, the following shall apply:

• MODES – requirements are mandatory.

• MOTS – requirements of MOTS-40 to MOTS-47 are mandatory. A gap analysis shall be performed against the FPSO Contractor’s engineering standards to determine which other MOTS are required to be applied and the resulting proposal shall be approved by the Technical Authority Level 1 (TA-1).

5.3 Operated by Others (OBO)

OBO facilities are facilities where the Company has a share of the licence but where one of the other Partners is the Operator.



MODES may be used as a guideline for assessment of OBO facilities when the operator has its own set of standards. In this case, formal waiver requests from the MODES shall not be raised as described in section 7.3 Deviations and Waivers, however Corporate Engineering and Projects (CEP) shall be informed of any major deviations.

When the operator does not have its own design standards, MODES may be applied to OBO facilities and projects with agreement of the operator.

5.4 In-service Integrity and Safety Management

The MODES forms the basis for the design integrity of the facilities. The Global Operations (GO) standards MOG-CPO-STD-0003: “In-Service Integrity Management Standard” and MOG-CPO-STD-0002: “Operational Safety Procedures” detail the company requirements to ensure the integrity of the facilities once operational.

5.5 Temporary Equipment

Temporary production equipment and facilities shall meet the requirements detailed in the MODES in addition to requirements of the MOG-CPO-STD-0003: “In-Service Integrity Management Standard”.

Other types of temporary equipment, e.g. well test skid, mobile generator set, etc., are not covered by the requirements of the MODES, but shall be covered by the BU’s standards/procedure/rules. These BU rules shall ensure that significant deviations to the MODES are adequately considered.

6. MODES Structure

MODES are split into the following separate parts:

• Part 00 - General

• Part 01 - Safety Design

• Part 02 - Process and Utility Design

• Part 03 - Electrical Design

• Part 04 - Instrumentation Design

• Part 05 - Telecommunications Design

• Part 06 - Structural Design

7.2.2 Company Design Guidelines

The MODES requirements are supported by a number of specific Company Design Guidelines. The Design Guidelines are informative documents only and are referenced in the relevant discipline parts of the MODES.

7.3 Deviations and Waivers

Deviations from the MODES shall not be permitted unless prior written approval is obtained by a request for a waiver from the Head of CEP. Proposals for deviations shall be prepared only when:

• Significant costs saving may be obtained, without compromising on Health, Safety and Environment (HSE) and operability requirements;



• New experience shows that the requirements are not suitable for the design or work being performed;

• Concepts or requirements specified are not possible or feasible to fulfil.

Requests for deviations or waivers to the requirements detailed in the MODES shall be made following procedure MOG-EP-GEN-PRO-0203: “Technical Authority and Waiver Procedure”.

8. Overall Design Requirements

8.1 Design Objectives

All facilities shall be designed to support incident-free operations, in particular:

a) To operate safely, efficiently and reliably within the agreed design envelope.

b) To operate and be maintained cost effectively in line with the agreed operating philosophy.

c) To minimise impact on the environment.

8.2 Field Development Planning

Documents generated during the Field Development Planning phase of the project will include:

a) The selected facility concept for the development as described in the Field Development Plan (FDP).

b) Operating and Maintenance Philosophy.

c) Basis of Design (BOD) for the facilities.

Jointly with the MODES, they shall form the basis for the design of the facilities.

8.2.1 Operating and Maintenance Philosophy

An Operating and Maintenance Philosophy shall be prepared specifically for applicable developments describing the manner in which operating and maintenance activities shall be optimised during the design process. The philosophy shall address the intended organisational model and structure for operations and maintenance.

8.2.2 Basis of Design

A BOD shall be established for each development and shall define the design data required for the design of the development.

The BOD should be a frozen at the end of Select phase and any subsequent changes to the BOD shall be subject to Management of Change process.

The BOD document is descriptive in the early phases of project maturation but, as the design matures, becomes more prescriptive as design parameters for each system are set and the writing of design philosophies removes the requirement for explanation in the BOD document.

Critical design parameters such as wellhead flowing and shut-in pressures and temperatures, design flowrates (minimum, daily average, peak), well fluid compositions, export specifications, design parameters for any relevant existing facilities or infrastructure, and key environmental parameters (min/max ambient conditions) should be included in the document. These parameters should be placed on HOLD if not known in initial revisions of the document and plans/work packages initiated to clear such HOLDs as soon as possible.

Environmental parameters (wind, waves, currents, temperatures, earthquake, etc.) shall be determined based on the requirement in the ISO 1990X series of standards. These shall also



apply for environmental parameters to be used for topsides design (wind, temperatures, earthquake loads, etc.).

The BOD shall address the scope allowances to be made for future expansions and tie-backs.

8.2.3 Design Life

The design life for the new facilities shall be minimum 25 years. However, factors such as long or short remaining concession life or anticipated design lives for floating facilities, etc., where field life may be shorter can determine a shorter or longer design life. Required design life shall be stated in the BOD.

The required design life for brownfield projects shall be subject to review in relation to the mature field status and decisions towards facing out of facilities.

8.3 Design Practice

The design practice described below shall be used for asses, select, define and execute stages of the PMP, including both large and small scale designs, greenfield and brownfield, and should be adjusted to be practical considering the scope of design activity.

a) Ensure that design team is competent, whether in-house or external.

b) Ensure that the BOD is adequately defined.

c) Ensure that the operating and maintenance philosophy is adequately defined.

d) Ensure that hazard identification and risk assessment activities are performed in line with the requirements of MOG-HSSEQ-SAF-STD-0006 “Risk Management” and MOG-CEP-SAF-GDE-0305 “Process Safety Activities for Projects”.

e) Ensure that Performance Standards are defined for all Safety Critical Elements.

f) Prepare a design, based on local legislation, good engineering practice, the industry standards and Maersk Oil specific requirements as laid out in this standard.

g) Prepare a Environmental Impact Assessment (EIA), if required by local legislation or if the actual facility design activity has a significant environmental impact.

h) Prepare Authority documents (Safety Case or similar, as required) including the final QRA and EIA.

9. Field Layout

The objectives regarding field layout shall be safety and operability, i.e.:

• Separation of the process equipment from populated areas, especially the accommodation area.

• Orientation against wind direction to minimise the probability that flammable and toxic (H2S) gas, and products from the flare(s) and vent(s) will reach populated areas, especially the accommodation area.

• Orientation against predominant wave and wind direction or landscape features onshore, such that safe evacuation is maximised.

• Waves and wind orientation to minimise risks associated with supply vessel operations and crane operations, e.g. platform separation, riser locations, pipelines, etc.

• Separation between platforms and orientation against waves and wind to allow safe placement of mobile drilling rigs and to allow safe drilling and logistic operations from mobile or permanent rigs and allow for a high uptime of such operations.



• Placement of floating production systems to minimise the interference with other activities, e.g. drilling and diving.

• Allow for future expansions.

9.1 Design Requirements

The geographic and climatic features of the development shall be identified. This includes, but is not limited to landscape/seabed levels, soil/seabed foundation properties, wind, wave and current data, third party features e.g. accommodation areas, pipelines, shipping lanes or roads, etc.

The basic features of the plant shall be identified, e.g. number, size, function of platforms/plants, number of wells, drilling rig requirements.

The optimum layout shall be developed based on the operational requirements supported by hazards identification and risk assessment activities.

10. Interfaces

A list of design interfaces (Interface Schedule) shall be established by the project team and regularly updated. Interfaces shall be given due consideration in the design process and designs selected shall ensure a safe over-all design with minimized operational restrictions. Design interfaces shall include, but not be limited to:

• Ongoing production operations

• Drilling activities and new and existing wells

• Existing platforms and facilities

• Marine activities and other traffic in the area

• Facilities operated by others including pipeline

• Facilities provided or installed by other contractors

11. Management of Change

In line with the requirements of MOG-EP-PRM-STD-0200: “Engineering and Project Quality Standard”, a formal Management of Change (MOC) system shall be applied and shall cover all phases of the project work by the Company.

During the early stages of the design process, this shall focus on key design documentation such as BOD. In the execution phase, MOC system shall be applicable to all major design changes, and, following a Detailed Design HAZOP Study, all changes shall be subject to MOC procedure.

12. Design Verification

Refer to MOG-EP-PRM-STD-0200: “Engineering and Project Quality Standard” for requirements for design verification.

13. End of Field Operations

The facilities shall be designed to allow removal of facilities safely and with a minimal impact on the environment.
