The North Field is the world’s largest natural gas field and accounts for nearly all the State of Qatar’s gas production. The principal objective of the NFPS projects is to sustain plateau from existing QatarEnergy LNG Operation – S1, S2, S3, N1 and N2 , production areas by implementing an integrated and optimum investment program consisting of subsurface development, pressure drop reduction steps and compression.
NFPS projects comprise 3 main investment programs:
- Investment #1: Drilling and Associated Facilities [WHP12S/ WHP13S/ WHP14S/

Equipment packages shall be designed for safe material handling (MH) as per “Mechanical Handling Philosophy (Doc. No. 200-20-PI-DEC-00012)” and shall comply with the Human Factors Engineering (HFE) design requirements contained in HFE Workplace Design Specification (Doc. No. 200-20-SH-SPC-00018).
VENDOR shall list all items’ weight and dimension that will be handled during maintenance period and this input shall be conveyed to EPC CONTRACTOR’s Material Handling specialist. All the specific handling instruction and recommended facilities to dismantle, extract and lift all parts of the package shall be described to EPC CONTRACTOR. Also, working space required for the maintenance activities shall be clearly defined in the general arrangement drawing, considering the HFE Workplace Design Specification (Doc. No. 200-20-SH-SPC-00018) requirement.
As a general guideline, items weighing more than 23kg should be lifted or moved using a hoist or trolley. Items weighing less than 23kg should be manually handled. Risk of injury increases significantly beyond this weight and these handling tasks require special attention in risk assessment. Mechanical lifting aids shall be provided to mitigate injury risk in these circumstances.
All maintenance and the associated lifting activities within the VENDOR package boundary shall be assessed and appropriate lifting solutions and special tools provided. These assessment, lifting solutions and special tools shall be part of the VENDOR’s supply.
All lifting devices such as slings, shackles and spreader beams required for handling of the complete package during transportation shall be part of supply and shall comply with “Mechanical Handling Philosophy (Doc. No. 200-20-PI-DEC-00012)”. The lifting arrangement shall be based on single point lift, unless otherwise agreed with the EPC CONTRACTOR.
19 HUMAN FACTOR ENGINEERING
All aspects of the design of the offshore facility, including VENDOR supplied equipment/ hardware, shall comply with the Human Factors Engineering (HFE) design requirements contained in HFE Workplace Design Specification (Doc. No. 200-20-SH-SPC-00018).
If there is a conflict between the HFE requirements contained in HFE Workplace Design Specification (Doc. No. 200-20-SH-SPC-00018) mentioned above, and other project design requirements, the VENDOR shall notify the EPC CONTRACTOR’s HFE Authorised Person immediately for a resolution of the conflict.
The VENDOR shall be responsible for the inclusion of HFE design requirement into their respective equipment design via the review of all relevant engineering documents, layouts, specifications,

drawings, operations and maintenance equipment manuals, etc., and in this role shall interface with the EPC CONTRACTOR’s HFE Authorised Person to audit that Human Factors Engineering principles and design requirements are “built in” to the respective equipment designs.
If the VENDOR is unable to comply with the specific design requirements listed above, it shall notify the EPC CONTRACTOR’s HFE Authorised Person immediately on reaching that decision and provide an explanation why an HFE design requirement cannot be met, substantiated with human factors risk assessment by a qualified HFE Specialist for EPC CONTRACTOR’s and COMPANY’s approval.
During the design and fabrication of a VENDOR-supplied equipment/ hardware/software, it is possible that the VENDOR site will be visited by either, or both, of the COMPANY and EPC CONTRACTOR’s HFE Authorised Person. The purpose of the visit will be to review the VENDOR design and/or fabrication progress. All visits will be coordinated with the VENDOR to set a time and date agreeable to all parties.
Any relocation of equipment/valves/auxiliaries due to accessibility issue shall be analysed for other operational consequences.
All action items or issues raised through the course of HFE reviews, visits or inspections shall be tracked and closed by the VENDOR in their respective HFE Issues Register.
20 THIRD PARTY CERTIFICATES AND LICENSE
Third party certificates available if any for cables, and associated accessories, shall be provided.
21 PERFORMANCE GUARANTEE
Unless otherwise agreed, the following shall be included:
All equipment shall perform satisfactorily under the specific operating conditions as detailed on this technical specification, requisition, the primary codes and standards listed here in and shall be fit for the intended purpose. Tests shall confirm the VENDOR’s guaranteed performance.
The VENDOR shall guarantee the overall electrical integrity, workmanship and the materials used for the construction. The VENDOR shall guarantee the cables for the warranty period and the conditions stated in the Purchase Order.
