Shell Normand Flower Crane Rigging Failure Analysis

Shell Normand Flower Near-Miss Incident

Bastion was contracted to conduct forensics analysis of structural failure in the Shell-Normand Flowers crane. Our team provided corrective actions to the joint investigation team and a new weak link analysis was developed to ensure crane rigging safety. Bastion quickly ensured the safety of Shell-Normand Flowers, Shell-Olympic Intervention, and Shell-Ocean Alliance (all ship crane activity previously shutdown due to accident) resulting in improved safety and significant cost savings.

Transocean LMRP Alignment Analysis

Transocean LMRP Alignment Analysis

Bastion was contracted to develop a protocol to safely disconnect (without damaging) the two systems and develop working procedures to insure this would never happen again. Within 3 weeks Bastion successfully developed corrective action and disconnected. Drilling was successfully restarted and completed, resulting in improved safety and significant cost savings.

Transocean Celtic Sea Structural Modifications

Transocean Celtic Sea Structural Modifications

Bastion was contracted to perform design and analysis for the ROV platform reinforcements, BOP support modifications, cement unit foundation, and numerous additional rig modifications. The project was successfully completed 1 week ahead of schedule and resulting in significant cost savings.

BP Dropped Objects Analysis

BP Dropped Objects Analysis

Bastion was contracted to develop a coupled loads simulation to predict the dispersion patterns for several objects (e.g., manifolds, jumpers, spreader bars, mud mats, etc.) during field workover. Bastion successfully modeled equipment excursion patterns to ensure safety of the field and reduced stand-off requirements by over 30% for some equipment, which resulted in improved safety and direct operational savings for BP

Design and Analysis for Turret Locking System

Design and Analysis for Turret Locking System for Noble Discoverer

The Noble Discoverer drill ship sustained minor damage after a mooring line failed in a storm. Noble Drilling hired Bastion to assist with the design and analysis of a modified turret locking and rotation system (LRS). The final design of the LRS incorporated a guide shoe, double pin locks and hydraulic cylinders as part of a redundant system.

500 Ton Offshore Crane Design

500 Ton Offshore Crane Design

Bastion was retained to provide structural engineering for the mast and boom of a 500 Ton offshore crane. The project scope presented numerous design challenges which were systematically solved within a condensed work schedule. Minimization of weight was of particular interest to the customer. Bastion engineers were able to reduce gross weight by 24% while maintaining 96% of the desired design rating.

Strength and Buckling Structural Assessment of Flying Lead Pallet

Strength and Buckling Structural Assessment of Flying Lead Pallet Design for Subsea Umbilicals

Bastion 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 subsea installations. 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.

Equipment Qualification Assessment Process for Subsea Umbilicals, Risers, and Flowlines

ExxonMobil Equipment Qualification Assessment Process for Subsea Umbilicals, Risers, and Flowlines

Bastion was contracted by ExxonMobil to refine their Equipment Qualification Process Specification and Standards development. We analyzed and implemented ideas from other industries to expand the assessment process regarding new and existing technologies for subsea applications. Our personnel provided expertise in API, ABS, DNV, AISC, and ASME requirements. Tasks included risk and reliability assessment, failure modes and effects analyses, qualification tests, and generating acceptance criteria, when warranted.
