  • Floating Production Semi-Submersible TRUSS JOINT MODELING AND ANALYSIS Bastion Technologies, Inc. was contracted to model and analyze three new truss joint configurations for a new semi-submersible deepwater drill rig. The goal of such an analysis is to use less tubular connections to support the entire deck load thus decreasing weight and facilitating inspection. Bastion structural engineers built three different bar to beam element models and ran over 700 load cases per joint in order to determine the optimal design. All models were built using FEMAP and calculated with NASTRAN solver. All supporting structural analysis was performed per ABS code requirements. All three designs along with the associated recommendations were delivered to the client for consideration.Entire Truss Structure Truss Joint FEA Model 8
  • STRENGTH & BUCKLING ASSESSMENT of FLYING LEAD PALLET DESIGN Bastion Technologies, Inc. performed a structural analysis on a flying lead pallet used to hold sub sea umbilicals for transportation, storage and installation. The pallets hold about 1,300 ft. of 3.5” diameter umbilical which is used for control related functions on sub sea installations. The fully wound weight of the structure is approximately 20,000 lbs. Bastion performed shell and structural strength assessments using NX/NASTRAN software and hand calculations for buckling due to lifting, transportation and storage of the umbilical. All required analysis adhere to DNV codes and standards.

  • BURNER BOOM FOUNDATION MODIFICATIONS and ANALYSISOur client needed a new foundation design for the relocation of the aft burner booms for a deepwater drillship. Bastion was contracted toanalyze both burner boom foundations located on the aft end of the ship. Redesign and analysis was necessary as a result of changes in loadingconditions and new requirements imposed since the completion of the original design. The new loading conditions require that the boom iscapable of moving up and down between 0 degrees (horizontal) and 45 degrees in elevation. The boom will also be required to swing inboardand outboard while at any angle between these two inclinations. Further, the client required that all reinforcements to existing structure mustbe added above the deck to eliminate interference with existing structures below deck; specifically in the vicinity of the dynamic positioningcontrol room. Any additional reinforcement was limited to approximately 350mm in height. The burner boom is designed in accordance withAmerican Bureau of Shipping (ABS) rules and guidelines (ABS Rules for Building and Classing Mobile Offshore Drilling (Ref 4.2), and theguidelines of the American Institute of Steel Construction (AISC), Manual of Steel Construction, Allowable Stress Design (Ref 4.1).

  • Structural Evaluation of Drilling Rig Mast With 750,000lb Hook Load RatingBastion was requested to conduct a structural analysis and evaluation of the mast of adrilling rig with a rated hook load of 750,000 pounds. The rig is a 1500 horsepower“slingshot” type land rig with an unguyed mast. The mast is an open truss type structurewith a height of 148ft. The STAAD Pro structural engineering finite element programwas used for the structural analysis. .The table below shows the mast front and side elevations taken from an assemblydrawing. This is the final static load case table. It was created by varying the B750 hookstatic load, the stand percent and the wind speeds. This gave eight major static loadcases. The analysis validated the rated hook load as a function of wind speed chart forthe structure. B750 Mast Static Load Cases B750 Mast front and side elevations 11
  • Strength and Buckling Analysis of Offshore Crane Pedestals Bastion Technologies, Inc. was contracted to analyze the structural integrity of a relocated crane pedestal and its immediate supporting structures on the starboard side of Jack Up Vessel “Thule Energy Hull 051”. The crane is a Type C pedestal mounted rotating crane per the American Bureau of Shipping (ABS). A FEMAP model was created for both the crane pedestal cylindrical thick-wall column and three supporting deck panels with plate elements. The stress results were solved using MSC/NASTRAN solver. Additionally, a hand calculation and verification was provided to prove the subject structure has adequate buckling resistance strength according to ABS, AISC, and API codes. A report was written to show the designs specified in the reference drawings are structurally sound with respect to strength and buckling resistance when both the dead weight load and maximum operational loads are simultaneously applied at the top of the crane pedestal. The complete stress report addresses the strength and buckling assessments for this pedestal and its immediate supporting structure. The report was used to verify standards compliance of the crane pedestal design. The final report was submitted to ABS.

  • Analysis and Re-rating of ASME B16.5 Flanges for Offshore Metering Skid Chevron-Shamrock ManagementA manufacturing company in Houma, LA was contracted to build metering skids for a major oil company. The fabricator usedASME B16.5 rated flanges as part of the construction. In order to maintain alignment, the fabricator machined the flange facesand consequently nullified the ASME rating. The fabricator asked Bastion Technologies to provide an analysis of the 12” and 16”sizes of the 150# flange in order to validate the performance per ASME B16.5. The 12” flange passed without condition,however the 16” would not pass the leak test under the torque conditions specified per B6. A special bolt torque procedure wasgenerated in order to achieve the desired performance. The upper and lower torque limits were verified by FEA stress analysisand hand calculations. 16” Flange von-Mises stress on flange face FEA and hand calculations for torque 13
  • Design and Analysis for Installation of Utility Crane Pedestal on Noble Danny Adkins BOP TransporterBastion Technologies was retained by Noble Drilling to provide a design and analysis of a utility crane pedestal. The pedestal is tobe attached to the top of an existing BOP transporter for the Noble Danny Adkins semi-submersible rig. The crane pedestal wasengineered for both strength and buckling. The Bastion Technologies engineering team coordinated the design with the customersengineers in an iterative process which produced a cost effective design ahead of schedule.

  • Rhodia Chemical – Baytown Analysis of Tower/Deck WalkwayBastion Technologies was asked to provide an analysis of the Rhodia Chemical – Baytown Plant, tower deck walkway. Rhodia maintenanceand operations employees expressed concerns that the walkway was not safe for personnel. Specifically, the employees had objection to theamount of flex allowed by the Chemgrate panels spanning the transverse supports of the walkway. Following analysis of the duct andwalkway, it was determined that the panels did in fact allow excessive flex beyond that allowed by OSHA. Also, the transverse supports failedunder the specified load condition per AISC. It was recommended to Rhodia Chemical that the walkway be condemned until modificationscould be made to the design.

  • Mechanical Engineering
  • LMRP Alignment Analysis December 2009Bastion Technologies, Inc. was contracted by a leading deepwater drilling company to model and analyze the motion of a LMRP assemblyfor representative wellhead tilt. In performing the analysis Bastion engineers considered three different tilt scenarios, a 1 and 2 degree tiltabout the cone pin axis and also a 2 degree tilt perpendicular to the cone pin axis. The goal was to analyze expected damage to the chokeor kill slabs due to alignment error, calculate alignment error with tolerance effects using current pin design and analyze expected damageto cone pins and cone pin slot during engagement. ProE 3D was used in conjunction with NASTRAN 601 to perform the analysis.Bastion engineers determined the spherical pin design produced a constant alignment error which forced motion of the LMRP to becontrolled by one set of spherical pins and the cone pin. This condition caused damaging wear to the cone pin and cone pin slot. Further,the misalignment at engagement of the choke/kill side stabs resulted in damage to the lands and likely leakage.It was determined that the defect was in the design of the spherical alignment pins. Removal of the spherical pins and replacement with anew straight pin design was recommended. The new straight alignment pin design resulted in an error of less than 0.077 degrees vs. 0.3degrees when the spherical pins were used. The resultant forces at the stabs reduce the stress from a value above the Brinelling stress to avalue of 37 KSI. Collet Connector at 2 deg.
