6.3 Schedule of Deliverables The Completions, Pre-Commissioning, Commissioning and Performance testing activities identified and planned to be executed in three discrete phases and these phases are defined as follows:

• Planning Phase • Execution Phase • Operations Phase Commissioning Delivery Plan

6.4 Planning Phase

During the planning phase, as illustrated on the Delivery Map the Commissioning deliverables will be developed in a logical and systematic manner by Commissioning professionals and will comprise of the following activities:

6.4.1 Define the Systems

The main Systems will already have been set by the Design Engineer. These Systems will be reviewed and checked by the ICAT and if necessary adjusted or reset for CSU purposes. This activity also allows for a set of specific identifiers for Commissioning and Start-up to be developed.

6.4.2 Set sub-system limits

Where practical, limits for sub-systems are identified to break down the Commissioning schedule into smaller, manageable blocks of work that will help to optimize the Commissioning program. This is performed on PFDs, or if available P&IDs.

6.4.3 Prepare Commissioning Procedures

Develop Procedures in the agreed formats to derive the detailed commissioning activities for the overall Project; this includes the subsequent handover of responsibilities from one group to the next. The procedures are broken down into subsystems where meaningful commissioning can be achieved on part systems.

6.4.4 Set the CSU sequence logic and milestones

Once the Commissioning Systems and sub-Systems have been identified and the equipment allocated to them, this should give enough detail to work out the CSU sequencing and priorities. From the details prepared by the preceding activities, an initial logic for Commissioning and Start-up is prepared by System and sub-System showing sequences, predecessors, successors and concurrences for each of the systems identified. Milestones are also identified at this stage.

6.4.5 Prepare Manpower estimates

From the details contained within the Commissioning Procedures, manpower estimates are generated to determine how many and what type of operatives will be required to complete the activities listed.

6.4.6 Prepare the CSU plan

The CSU Plan uses the logic to list the activities that are aimed at proving either the functionality of the design or the correct installation of Plant and equipment such that it meets the Project acceptance criteria and the sequence of events required to be executed to reach a safe and effective plant start-up. Associated with this plan is a manpower estimate and a cost estimate. These will be prepared using standard norms for estimating and expected costs for the manpower. The completed CSU Plan illustrates which Systems and sub-Systems are to be commissioned and started up safely in the optimum sequence and has resources and durations allocated to show manpower requirements for each activity.

6.4.7 Integrate the CSU Plan

When the CSU plan has been developed, it will be integrated with the interfacing departments and Engineering, Construction and Operations to ensure that the plan fits with the sequence of activities of these parties, is achievable and can meet all the required milestones.

6.4.8 Prepare the Leak Testing strategy

Using the CSU marked-up drawings, work out the boundaries for leak testing hydrocarbon systems and sub-systems, noting that there may be requirements for additional isolations, vents and drains and break flanges.

6.4.9 Prepare Workplace risk assessments

Preparation of Safety and Workplace risk assessments for each Commissioning procedure to ensure that occupational safety is not compromised during completion and testing activities.

6.4.10 Identify Commissioning Management Tools

Review the availability of tools for helping the management of Commissioning and Start- up and recommend which of these will be of use to the Project.

6.4.11 Populate Commissioning Management Tools

Set up and populate the chosen Commissioning Management tools with the required data from Engineering, Vendors and Fabricators.

6.4.12 Prepare preservation procedures and schedules

Identify the equipment which will need to be preserved from delivery up to operation and using standards plus Vendor preservation recommendations, prepare the necessary procedures and schedules for preservation and set up the CMS database to handle the preservation program.

6.4.13 Prepare Vendor attendance plans

Study the lists of equipment and decide which of these will require on-site attendance from the Vendor, in addition to the Commissioning team already present. Typically, this will be for major package or complex equipment.

6.4.14 Prepare plans for SIT/FAT

Similarly, whilst studying the Vendor lists, decide which of this equipment will require a visit to the Vendors works to conduct Factory Acceptance Testing prior to shipment to site, and which equipment will require to undergo Systems Integration Testing as part of the CSU process.

6.4.15 Prepare Sub-Contractor plans

Study the Commissioning procedures and decide which Sub-Contractors will be required for specialized areas. Prepare mobilization plans for these Sub-Contractors using the integrated plan.

6.4.16 Identify and schedule OR requirements

Work with the Client Operations Team to identify the Operational Readiness requirements used and prepare the schedule of requirements that will be required to be followed during execution of the Commissioning and Start-up program.

6.4.17 Prepare the PSSR Procedure

In conjunction with the Client Operations Team, prepare the procedure for the Pre-Start- up Safety Review that will be required to be performed in between the Commissioning and Start-up phase.

6.4.18 Identify Plant and temporary equipment requirements

Through studying the Commissioning Procedures and the appropriate Project documentation, the requirements for Plant, tools, test equipment, consumables and temporary equipment required for pre-commissioning, commissioning and start-up activities is determined and listed.

6.4.19 Identify Commissioning and Start-up spares

Consolidated lists for spares covering Commissioning, Start-up, Insurance and Operations are generated using information generated by the Designer and the Vendors. The lists are checked against Vendor recommendations, adjusted and optimised as agreed before preparing a schedule for phased delivery.

6.4.20 Prepare Initial and Final fill schedules

Study the equipment lists and Vendor data to assess the requirements for fills, lubes, catalysts, oils and greases and compile a comprehensive list of these to be installed during Commissioning and start up.

These audits may be performed remotely and where necessary Site visits should be allowed for. Audits are recommended as follows: • 20% into population of engineering data (when the team organisation is in place) • 80% population of data (just before site execution) • 10%-20% into first handovers from construction (with/without pre-commissioning) • Before the first start-up.

6.11 Reporting Reporting by Rev1 will comply with the Dangote’s Management requirements and schedule. As a minimum, Rev1 will submit a weekly progress report covering the following listed subjects (not limited to): • Contractor’s performance • HSSE / QA reporting and issues • Security performance and issues • Resource planning and reporting • Summary of highlights and achievements • Actions completed in the period / actions outstanding • Areas of concern / mitigation • As required by the Dangote’s Management, Rev1 will provide requested information into the Company monthly project report or any other periodic as necessary. • Handover Documentation The Integrated Commissioning and Acceptance Team ICAT shall be responsible for the handover of systems to Company Operations. Effective handover of systems is key in ensuring that the appropriate information is made available to allow the receiving party to accept completed systems without delay and to demonstrate that project requirements with regard to verification of system integrity, operability and performance has been achieved in line with design intent. In line with project delivery best practice, ensuring common processes and procedures are implemented across all project phases, Rev1 recommend that an integrated project handover philosophy is implemented ensuring consistency and structure across each project phase. Therefore, on award of contract, Rev1 shall work with the Dangote to ensure that the handover process at mechanical completion is adequate. On completions of commissioning activities, the Commissioning team will handover systems in line with the agreed project handover philosophy. Rev1 propose that control of handover is managed via the project CMS. The use of the CMS to manage handover of commissioning work scope will ensure a structured process is used in line with the existing process developed for the handover of work scope from the Company. The CMS will also allow for the recording of commissioning punch lists enabling the Commissioning team to deliver to the Company a comprehensive record of all punch list during the life of the project. The CMS shall also be used for the compilation of the handover documentation as required by the project handover philosophy. Development of final handover packs will be completed by the Commissioning team once work scope has been verified by all key stakeholders as complete. Prior to System

Handover, notification will be given to Company to enable joint walk down of completed systems to be undertaken and to ensure that any outstanding items have been identified and agreed prior to submission of the handover pack. As a minimum, the handover pack shall include (subject to final agreement with the Company): • System Handover Certificate • System Punchlist identifying outstanding items at time of handover • As-built P&ID, SLD’s etc. and any other applicable documentation, identifying status of the facility at time of handover Confirmation of close out of EQ’s, SQ’s etc. and any other applicable MOC documentation Completed commissioning certificates and procedure as applicable to the handover A handback Procedure will be developed to facilitate custody ownership / transfer of incomplete systems, or sub-systems. Resourcing Summary Scope of Services Rev1 will provide: • Trained and competent commissioning personnel to support project. • The personnel provided by Rev1 will include: • Commissioning Manager

• Commissioning Discipline Team Leaders • Commissioning Discipline Technicians • Start-up & Turnover Engineers • ICAT Coordinator • Certification Engineers • Commissioning Engineers • Database Engineers

• Vendor/ Materials Expeditor • Safety/ PTW Coordinators • Planner/ Scheduler • HSE Advisors • Resource Planning • Manpower Plan

The Commissioning Manager will maintain the manpower plan for each of the Completions, Commissioning and Acceptance phase of the work scope to allow effective management of resources throughout the contract duration. The manpower plan proposal document comprises a schedule for the mobilization / demobilization of manpower to the project, in line with the work scope delivery plan and schedule. Management and maintenance of the project manpower plan will be the responsibility of the Commissioning Manager. 7 RESOURCING STRATEGY As a market leader in the supply of specialist completions and commissioning resources, Rev1 have access to a comprehensive resource pool of competent and experienced personnel currently being mobilized to major projects globally in roles ranging from Technician to Lead Engineer and Manager in both commissioning and completions disciplines. Our dedicated Technical Resourcing team have access to Rev1 in-house web-based candidate databases. 7.1 Selection and Screening The Technical Recruitment team having identified suitable candidates using the agreed Job Description (JD) and Personnel Specification (PS), will initially screen the candidate using evaluation criteria identified within these documents, to produce a short list of candidates. Activities related to initial selection of suitable candidates will include: • Screening of experience and competency against JD/PS • On completion of the initial selection activities, the short-listed candidates, subject to their role, will undergo further evaluation using a range of methods which include practical mechanisms such as: • Technical skills screening (test – for trades) • Safety behavioural screening (test) • Technical and Competency based interviews All personnel engaged must achieve the minimum standard as defined within the applicable JD/PS and be successful in either the applied trade test (for Senior Technicians and Technicians) or technical interview (for Manager, Team Leads and Engineer). • Confirmation of qualifications • Confirmation of training records • Reference checking (where applicable)
