Introduction The Basis of Design describes the requirements of ConocoPhillips Grissik LTD (CPGL) for the development of the Sumpal Expansion Project. The Sumpal Gas Station is a part of the Corridor Block PSC (Production Sharing Contract), located 40 km South-West of Grissik in South Sumatra. The Corridor Block PSC is a 54:36:10 joint ventures between ConocoPhillips Grissik Ltd, Talisman Energy and Pertamina. CPGL is the field operator. The existing Sumpal Facilities have been designed to process 165 MMSCFD of raw gas from the Sumpal field and to produce 155 MMSCFD of dehydrated gas which is further exported to CGP at Grissik for gas sweetening and onward sales. In order to meet GSPL contracted gas delivery and maximize the recovery of remaining gas resources from the Sumpal field, the Sumpal Facilities will be increased to export the dehydrated gas from 155 to 310 MMSCFD by first quarter 2013. The results of the concept selection study, has suggested that an identical gas processing facilities with the same capacity as the existing Sumpal Phase 1 (155 MMSCFD) is required to be installed to meet the above targeted dehydrated gas rates to CGP.

k ~the Location Sumpal Gas Station Figure 1.1 Corridor ~ l o c k and The Sumpal Expansion Project involves the iristallation of addiliorial woll fluid processing capacity in the Sumpal Gathering Station. 'The project requires tie-in of Sumpt~Iwell N7, a new 1 6 Duplex SS flowline and extension of llie existing inanifold, a new second gas processing train, a new 1 6 pipeline loop trunklirie from tlie S~~rnpal Gas Gatlieririg Station lo the Sumpal Junction and the associated utilities and offsites facilities. The tlehydt-alccl gas will be delivered to the Grissik Central Gas Plant tlirougli the 20" trunk line from Sumpal Junction for further processing. The Surnpal Expansion Project is a brown field rmiodilication irerice ilio insisllaliori of equipment will be undertaken while the existing plant is it1 oporotiorl a11d will1 minimal disruption to tlie existing operations.

4 . Underground Fire Water metallic piping shall be exempted from formal stress analysis and shall be assigned Lines Category 1. ADDITIONAL NOTES: 1. Large reciprocating equipment (if any) which requires dynamic analysis for induced vibration shall be covered by a separate study done by a Specialist Consultant.

2. The following lines do not need to be stress analyzed: Non-hydrocarbon lines such as air lines and water lines including potable water, service water, etc. All lines which discharge directly to atmosphere and which are not subjected to large thermal gradients, including atmospheric tanklvessel vents. All lines which are part of skid mounted packages (i.e. under the scope of package Vendors). All small diameter piping (1% inches and below) unless subjected to surging such as relief and blow down (to be clearly identified on the P&IDs). All drain systems piping including open drain and closed drain systems.

Approximate Methods for Simplified Analysis

1.0 Guided Cantilever Method For an 'L' shaped pipe work, from the structural theory, the permissible deflection, 6 is given as:

Where: 6 = lateral deflection (mm) L = deflected leg (mm) S = bending stress due to lateral deflection (Nlmm2) = 137.9 N/mm2as allowable bending stress for CS materials D = outside diameter of pipe imm) E = Young's modulus (Nlmm ) = 203400 ~ l m m (for ' CS materials) The leg required for lateral deflection is:

Knowing diameter and deflection the flexible leg can be determined Example: What is the length of the flexibie leg if the pipe size is 12 inch and the required deflection is 60 mm?
