Allowable Nozzle Loads Specification 0344-MI20-00S1-0100, Rev. C
EXECUTIVE SUMMARY This specification covers the minimum required allowable loads on process piping nozzle terminations for all types of equipment as referenced.
2.0
BACKGROUND OSX 3 Leasing B. V. (“Client”) is developing a deep water discovery in the concession areas related to the Campos Basin, off the coast of the state of Rio de Janeiro. The Client invited MODEC International, Inc. (“Company”) to tender FPSO specifications for a VLCC Conversion scenario. The FPSO will be turret-moored in a maximum water depth of 110 meters. The FPSO will receive production fluid from 2 well head platforms (WHP) and 2 satellite subsea wells connected directly to the FPSO. The FPSO will have production facilities to process fluids, stabilize them, and separate produced water and natural gas. Processed liquids will be metered, stored in the cargo storage tanks, and offloaded to trading tankers. Produced gas shall be compressed, sweetened, dehydrated, and used as a fuel gas and for lifting oil production. Surplus gas will be exported through a gas pipeline system or reinjected into the reservoir. Produced water will be disposed of overboard after treatment. The Process Plant shall have a capacity of production and treatment of 100,000 bpd of crude oil (at 15.6°C and 101.3 kPa abs), gas compression range capacity from 50,000 Nm³/d (at 20oC and 101.3 kPa abs) to 1,500,000 Nm³/d (at 20°C and 101.3 kPa abs) with a gas injection pressure of 35,000 kPa and de-sulphated water injection capacity of 150,000 bwpd (25,000 kPa). The FPSO will be designed to sustain optimal functioning for twenty years without dry docking and will be constructed primarily to perform the following functions:
3.0
•
To receive produced fluids from the wellhead platforms
•
To test the wells
•
To process the produced fluids
•
To store processed crude
•
To offload processed crude to trading tankers
•
To send treated seawater for injection to the wellhead platforms
•
To send electrical power to the wellhead platforms
•
To send gas to the wellhead platforms for gas lift and gas injection
•
To transfer communication/control signals between FPSO and the wellhead platforms
•
To have a minimum crude oil storage of 1,300,000 bbl (or at least 13 days of production)
BASIS This document defines the Company’s allowable nozzle loads for Static Equipment, Rotating Equipment, and Special Equipment such as those contained with Packaged Units. Various Industry Standards are specified for the Supplier to observe in their design. Special attention

Allowable Nozzle Loads Specification 0344-MI20-00S1-0100, Rev. C
Local stress in vessel wall resulting from nozzles or attachment loads shall be determined by applying one of the following methods:
5.0
WRC Bulletins 107 and 297. The using of WRC 297 is mandatory in order to validate the thickness of the nozzles.
Finite element analysis (FEA). The resulting stresses shall be evaluated using the allowable criteria of Appendix 4 of ASME Code, Section VIII, Division 2.
STATIC EQUIPMENT: ALLOWABLE NOZZLE LOADINGS Standard nozzle loadings for items designed according to ASME VIII Div 1 or 2 shall be in accordance with Table 1. For blast conditions, nozzle loadings as specified in Table 1 shall be increased by 33%. Nozzle loadings shall be considered as being caused by 67% thermal and 33% dead weight load. Nozzles or oblique nozzles or tangential nozzles (when the angle between the axis of the nozzle and the line normal to the shell/head surface exceeds 45°) shall be calculated individually The below specified loadings are applicable to nozzle sizes up to and including 36.” For larger sizes, actual individual loads shall be submitted to the equipment Supplier.

Vessel designed according to ASME Code Section VIII The basic stress intensity limits shall be per ASME Section VIII, Division 2, Appendix 4. The maximum allowable stress values S or Sm shall be based on the applicable division of the Code used for the pressure vessel design. For the occasional loads, in place of Sm value, use 1.2 * Sm For blast loads, in place of Sm value, use 80% tensile strength.

All forces and moments act on the intersection of the axis with the-thickness of the shell or head plates.
4.
The Supplier shall notify the Contractor of cases where calculations require an increase in thickness of the reinforcing greater than construction code and/or guide drawing mini. Allowable thicknesses. In such cases, if notified at the same time of quotation, the standard load may be reduced by the Contractor upon written request by the Supplier. Such agreed specific load shall be indicated on the equipment guide drawing.
5.
All cost for the above reinforcement must be included in the Supplier’s price.
