GeneralFacility Information:
Company: Dolphin Energy Limited Qatar Operation
Location: Ras Laffan Gas Plant, QatarUnit: Fire Zone:FZ02 Unit:144 Tag #: 144-OT-1001 Name:Construction of Liquid Sulphur Storage Tank
Project ID: DEL QOP
Study Duration:
Start: 6/13/2011
End: 6/13/2011
Methodology:
Type: Task Risk Assessmentas per QOP OMS Procedure QQH-GEN-0000-FRP-00025
GENERAL:The new Sulphur Tank will be constructed using two construction methods; (1) conventional tank construction for Tank shell co urse 5 and 6, and a temporary roofdome structure (2) using a Hydraulic Tank Jacking Equipment to install Tank shell course 1, 2, 3 and 4. This TRA will cover both construction methodologies.
CONDITIONS:1. Tank foundation, bottom and annular plate installation is completed with all NDT and radiography completed.2. All pre-fabricated parts required for the construction of the tank is shipped from the DOPET yard in DELWA to the construction site in the Dolphin Facility.3. All fabricated parts shall be identified with Tank No, Part No, Item No and Drawing No.4. All pre-fabricated items are properly supported and packed for transport from the DOPET yard in DELWA to the construction site in the Dolphin Facility.5. All Hydraulic Tank Jacking equipment shall have valid 3
rdParty Inspection Certificates.
6. All other lifting equipment used during the course of work shall have valid 3rd
Party Inspection Certificates (expect field welded lugs which will be inspected bycompetent welding inspector from DOPET or PMT).7. All tank construction work shall comply with the Dolphin PTW and Safe Work System.8. Four (4) Naked Flame Permits are allowed during the construction of the Tank; when additional Naked Flame Permits are required then the requirement shall bere-assessed by QOP ( Based on the quantum of work permitted without causing distortion due to welding).9. QOP approved Rescue Plan in place.10. During the lifting process all required guy wires (4) shall be in place to maintain tank stability.
11. Guy wires shall be installed and the roof will have four (4) open areas (no plate installed) to prevent movement or lifting of the tank during high winds and forventilation.12. Maximum number of personnel allowed inside during lifting of tank shell using hydraulic jacks is 6 people (two hydraulic jack operators, two helpers, and twosafety watch).13. Maximum number of personnel allowed inside the tank area during welding of shell course 5 and 6, and roof structure is 1414. Maximum number of personnel allowed inside the tank area during welding of shell course 4, 3, 2 and 1 is 10 subject to work conditions.15. Maximum number of personnel allowed inside the tank area during vacuum box testing of bottom plate welds is 4.16. No lifting activities (crane operation) if wind speed is above 20 knots as per Dolphin standard.
