3.2 Definition Company: Total or Total in joint venture and in the present case, the Cost Estimating entity. Contractor: Engineering Entity or Joint Venture under contract with Company for the FEED or BED. Sub-contractor: External firms in contract with Contractor (including Vendors). Engineering (E of EPC): Engineering services related to detailed studies (including procurement services), construction supervision services and contractor temporary site facilities. Procurement (P of EPC): refer to the main equipments and bulk purchasing activities Construction (C of EPC): Construction activities on site (civil works, structural steel, mechanical erection, electricity, instrumentation, painting, insulation..) or at yard Commissioning The integrated application of a set of engineering techniques and procedures to check, inspect and test every operational component of the PLANT. ISBL: InSide Boundary Limit; Geographical area where are concentrated process equipments (columns, exchangers, drums…). OSBL: OutSide Boundary Limit; External parts of ISBL area, corresponding to utilities (generation and distribution) and off sites (storages, product logistic, well pad, manifolds, remote compressions stations) Grass Root (or Greenfield): Project is defined as “grass-root” when works are executed in a free area where construction activities are under the full responsibility of the contractor. Brownfield: Project is defined as “Brownfield” when works are executed: • in a free space inside an existing production site, requiring safety permits and regulations for construction operations provided by the contractor under derogation of the company • or directly within the existing production site, with safety permits and regulations for construction operations provided by the Company (Simultaneous Operations-SIMOPS) Revamping: Project is defined as “revamping” when works concern modifications of existing process units ( ie debottlenecking). Material Take Off: Listing of material with specifications and dimensions potentially not summarized Bill of Quantities: Material Take Off, sorted, quantified and summarized according to a specific format. Each MTO must be issued with the corresponding BOQ. Direct Productive man-hours: Defined as hours spent by all disciplines teams from workers to foreman (i.e. Workforce) for construction of permanent installations. Hours related to staff management (supervision, secretaries) and hours related to temporary installations (like scaffolding) are excluded (= Indirect productive hours). Standard Man-hours are defined as US Gulf Coast basis (where local productivity = 1). Indirect Productive man-hours: Hours spent in support of the workforce performing the measurable work i.e. material handling, scaffolding, construction equipment maintenance, site cleaning, supervisors and inspectors.

Non Productive man-hours: Hours spent by the workforce not directly linked to the physical progress of the work i.e. which result from work interruptions/stand-by, waiting for material, interface problems, waiting on work permits, accidents, sickness. Local site travel and meal time may also considered as non-productive man-hours depending on the regulation and context. Non technical hours related to management i.e. project management team. Productivity: During cost estimating phase: Productivity is the ratio between the necessary number of manhours for the achievement of the given work on a given site and the necessary number of manhours to achieve the same work on the reference site (defined as US Gulf Coast basis.) During Project phase: Productivity is defined as the ratio between the realized or measured direct productive man-hours and the planned or anticipated direct productive man-hours which takes into account the local productivity. Note: If the realized productivity is =1 it means that the anticipated local productivity during estimation was correct. If it is <> 1 it means that the local productivity is better or worse. Technical Allowance: Percentage to be added to quantities to account for routing variations, lines diameter adjustment, plot rearrangements during detailed studies. The technical allowances are based on contractor’s experience on past projects. Material Take Off Allowances: Percentage to be added to the measured quantities because: • the relevant scope is not included in the FEED/ BED contract, • it would consume too much time and it does not worth it, • information is not available at this stage of development. For Offshore, the Material allowances are given by GS EP STR 001. Purchased Allowances: Percentage to be added to the quantities plus material take off allowances to take into account the cut and losses. The Purchased allowances are based on contractor’s experience on past projects.

the auxiliary equipment (ie for a compressor, its driver(s), lube oil console). These equipment lists concern ISBL units but also OSBL units. However, it is acknowledged that the equipment lists may include some equipment which are considered as main equipment due to their importance in the operations or due to their costs or their manufacturing duration (Crane, transformers, HV motors, special valves etc). Should these equipments be included in the equipment list, they shall be however clearly segregated from the previous ones to prevent distortions on application of estimating ratios. All other equipments not listed in the equipments list but incorporated in the plant shall be considered as “bulk material” At the end of FEED/BED, the equipment lists are deemed to be complete. Should this stage not been reached, an explanatory note shall be issued. The equipment list should include the capital spares ie spare for which the manufacturing time is as long as the item itself. 4.3.7 Summary Units For each process package (ISBL and OSBL) (storages, product logistic, well pad, manifolds, remote compressions stations), a summary unit shall be prepared. (See Appendix 2);

4.4 Onshore Facilities 4.4.1 ISBL / OSBL Units If the equipment lists are deemed to be complete, it is understood that at the end of FEED/BED, all bulk material quantities for a grass roots project for all disciplines shall not be measured through complete MTO’s prior to the detailed engineering phase. For brownfield / revamping projects, it is expected that the MTOs / BOQs shall have a level of detail corresponding to what is usually obtained in detailed engineering. All MTO’s shall be accompanied with BOQ’s.(See Appendices) Four methodologies are expected for the estimating of the quantities: • Parametric Models: This methodology uses parametric factors based on main equipment technical data to calculate for each disciplines (civil works, structural steel, mechanical erection, electricity, instrumentation…) quantities and construction man-hours. Such method can be implemented only if a process equipment list is issued and includes exhaustively all design data for each piece of equipment, such as physical dimensions, capacity, metallurgy, electrical power, pressure, temperature, etc…. • Semi detailed methodology: Quantities estimate is based on preliminary materials take off or analogy multiplied by take-off allowances to take into account all non measured quantities and additional quantities during detailed engineering. The take-off allowances are either based on contractor’s experience or specified by Company in the case of offshore facilities. The quantities generated by these allowances shall be always shown separately.

4.6 Brownfield / Revamping The brownfield or revamping activities at site are considered challenging by Company in terms of HSEQ, schedule slippage and cost overruns. In order to mitigate those risks, it is required to develop the engineering studies at the maximum level of detail possible at FEED/BED by conducting all necessary surveys and improving the quality of all take offs. This section deals with the methodology on Man-hour and POB estimates, and provides a list of required documents in line with this methodology. 4.6.1 Methodology of man-hour Estimates Man-hour estimates of brownfield modifications are normally conducted according 4 steps. 1. Definition of the (detailed) Scope of Work per discipline 2. Definition of quantities / volumes of per discipline by BOQ / MTO 3. Estimate of the required direct productive man-hours in the reference site by standard man-hour ratios with split between work to be prefabricated vs erected 4. Estimate of the total required man-hours on site by application of the following factors -

-

A local productivity factor related to the country of execution, to compensate for cultural/social differences ( tea breaks / unions obligations etc) but also due to climate aspects (hot, artic, monsoon). A site productivity factor, which takes into account:

For Onshore brownfield works: • The site conditions: Access to site, confined space, congested area • The operating conditions, SIMOPS or shutdown For Offshore brownfield works: • The Site conditions: inboard, overboard, confined space, congested area • The operating conditions: SIMOPS or shutdown. This gives the total of productive direct man-hours • A ratio of direct / indirect productive man-hours to allow for material handling, scaffolding, construction equipment maintenance, site cleaning, supervisors and inspectors. This gives the total of productive man-hours (direct + indirect) • A ratio of productive versus non productive hours or downtime coefficient to allow for interruptions/stand-by, waiting for material, interface problems, waiting on work permits,

repairs and reworks, accidents, sickness. Local site travel and meal time might also be considered as non-productive man-hours. Non technical hours related to management i.e. project management team are excluded. This gives the total amount of construction man-hours which shall be split into Direct and Indirect. Note 1: Particular attention shall be brought to the buildup of those factors: the Local Productivity factor sometimes also includes part of the downtime and even part of the site conditions. It shall be explained which effect is taken into account in which factor to avoid a doubling effect. Note 2: The man-hours provided shall concern the number of paid man-hours only. E.g. if transport from / to site is paid, it shall be noted if they are included in the downtime or compensated in the rate. Note 3: Management, Coordination, Engineering and any activities that are not related to construction are not part of this estimate. Example: 2000 meter cable (incl. contingency) needs to be pulled on a platform offshore Congo. According standard man-hour estimates this will take 0,3 hr/m and thus 600 hours. The local productivity factor for Congo is taken as 1.8 [-]. The site productivity factor for the offshore location is typically 2 during SIMOPS. The total of required productive direct man-hours is 2160 hrs. On average workers spend about 20% of their time on material handling and site cleaning. For every 10 workers there is a safety watch plus a supervisor. A total of 500 productive hrs of scaffolding is required, which is about 25 %. The total direct / Indirect ratio is 1.25x1.25x1.25 = 1.95 [-]. The total of productive direct + indirect man-hours is 4220 hrs. Daily the workers spend 4 hours on safety talks, breaks, permit signature and transfer from the bridge linked flotel. Mob / demob, occasional drills or standby due to heavy lifts count for an additional half an hour per day standby. The overall downtime coefficient is 12/7.5 =1.6 [-]. The total amount of estimated construction man-hours in this example is 6752 hrs or 563 mandays. 4.6.2 Methodology on manpower / POB estimates The number and distribution of POB on site/worksite determines the available workforce to execute the total amount of construction man-hours, and thus the duration of the work. For the construction period a manpower-planning shall be issued for the distinct phases of the work. Typical phases are before-shutdown/shutdown/after-shutdown phases or pre-work (e.g. Civil) / construction / commissioning and start-up phases. Phases can also depend on the available bedding at site. For each phase it shall be estimated what people are to be expected on site and their respective functions. Distinctions shall be made between Contractor and Company and those

contributing to the construction man-hours of the project and those who are not. In more detail, manpower can be looked at on a discipline level (e.g. Painting, Scaffolding, Electrical and Instrumentation, Piping/Mechanical, Etc.). By estimating the number of workers on the worksite (i.e. in direct vicinity of the works), it shall be verified a reasonable number will not be exceeded. Working in a congested area affects the site productivity factor and can compromise safety. A distinction shall be made between day and nightshift. Moreover for Offshore works, the logistic to be mobilized shall be investigated: • Availibility and use of a Flotel in the area • Mobilisation of a Flotel dedicated to the scope of work • Type of connection of the Flotel to the platform (Transfer by Gangway / speed boat / helicopter) which has a direct impact on both POB and productivity Example: The previously mentioned job offshore Congo is part of a bigger project. For execution of the offshore works a Flotel has been mobilized with 200 POB with a gangway for connection between the Flotel and the platform. In SIMOPS the maximum platform POB is temporarily raised up to 75. (see the figure below)

Due to the limited number of platform POB, a nightshift has been installed for some of the piping & mechanical activities. Safety watches, scaffolders and some E&I crew have been put in the nightshift to support their activities. The cables will be installed by the electrical crew in dayshift. Without supervisor safety watch or scaffolding the total construction hours for the electrical crew is 4321 hrs (=6752/(1.25x1.25)).

With a realistic maximum E&I POB on the worksite of 10 people, the cable pulling will take approximately 36 days. The scaffolding (before and after) will take about 500 productive hours, which is about 1000 construction hours (again, excluding the safety watch and supervisor). With 8 scaffolders this will take approximately 10 days (e.g. 7 to built, 3 to dismantle). Note that Project Management of both Company and Contractor is not included in the Manhours, but does take a significant part of the bedding and POB. 4.6.3 Required data For an adequate detailed estimate of the required man-hours for a brownfield work or project it is required to list and detail the following parameters (where applicable). • Number, weight and discipline quantities in mt, m, m², m3 or unit, which are to be -

dismantled, scrapped, revamped reused or temporary relocated

-

prefabricated as part of a module

-
