Offshore Fixed Structure Integrity management of offshore fixed structures is a full lifecycle process. It encompasses a variety of disciplines combined with a thorough understanding of regulatory frameworks and customer expectations in terms of managing the risk of failures associated with an asset or a group of assets. This process starts at the design level and continues until decommissioning. The asset integrity solutions team offers the following offshore fixed structure services: • SIM and reliability assessments to API or ISO Standards • Pushover analyses and determination of the reserve strength ratio • Risk assessment and inspection programs • Response of a structure to increased metocean conditions or due to brownfield modifications • Advanced analysis support for brownfield modifications • Rapid response, damage assessment services and anomaly resolution
Ongoing Upgrade: Life Extension and Structural Integrity Assessment Services for Esso Offshore Fleet in Bass Strait Customer: Esso Location: Bass Strait, Australia Ongoing upgrade/life extension and structural integrity assessment has been undertaken for Gulf of Mexico (GOM) first and second generations type offshore structure in Bass Strait. The structural integrity assessments of these platforms were required due to the platforms upgrade and updated environmental design criteria. Strengthening, modification and repair programs were developed due to damage, change of use or updated loadings including addition struts to four first generation platforms. It was also included the repairs or replacements for damaged caissons, risers and clamps. An extensive study including prototype testing and FE analysis was carried out for establishing the acual strength of complex joints of all first generation platforms.
Riser Guards Enhancement Study Project Customer: Esso (Australia) Location: Bass Strait, Australia The study investigated options to enhance the riser guard performances for Bass Strait offshore platforms for boat impact. The pilot study riser guards were selected based on type and population of the guards, condition reports and the minimum gap between the guard and the riser. The possible enhancement options were developed to improve reliability of the guards. An assessment criterion was developed to design and evaluate the enhancement options. The enhancement options was evaluated and ranked based on a comparison table including cost, constructability, energy absorption and structural requirements, additional protections and impact response performance.

Maintain Production Potential Program (MPP) Customer: Saudi Aramco Location: Kingdom of Saudi Arabia Saudi Aramco’s focus for the MPP in 2007 was the completion of the engineering construction packages for the platforms based on the ‘3S’ design principles (Standardize, Simplify and make Simultaneous Operations capable) developed by WorleyParsons Petrocon. The work encompassed 12 platforms and substantial tie-ins to existing facilities. WorleyParsons assisted Saudi Aramco on the refurbishment of the Marjan field ESD/control systems and various studies for the Karan field. Since commencing work on the MPP project in 2003, our team has delivered 40 new platforms, 85 platform upgrades, 165 km of pipelines, 100 km of submarine power cables, five cranes and over 300 well hook-ups. Over the next three to five years, the program anticipates including approximately ten platforms in the next work release, potentially followed by the major redevelopments of the Safaniya, Zuluf and Berri fields, with Safaniya alone including the installation of approximately 35 new platforms. This experience, coupled with initiatives such as 3S, ensures WorleyParsons continues to provide cost effective solutions for Saudi Aramco’s challenging development program.

RECENT ENGAGEMENTS
“WorleyParsons structural integrity group maintain the skills required to extend an existing facilities operation life or modify them to accommodate additional equipment required to improve or maintain production. In order to facilitate these modifications many innovative layout and the most advanced design techniques are employed to ensure the facility maintains the required structural integrity.� Reza GorJI Offshore Manager, Perth Office, Australia
Kumul Marine Terminal Integrity Assessment Customer: Papua Oil Search Ltd Location: Papua New Guinea The structural integrity assessment of Kumul Marine Terminal (KMT) Platform was required due to the platform life extension to 2043. The structural Basis of Design was developed for the structural reassessment of the jacket, deck and piles for the life extension. The structural integrity assessment of Kumul marine terminal platform was also required due to inspection and anomaly reports, new soil data and the platform dynamic monitoring (site measured dynamic response). In-place Strength, Fatigue and Seismic analyses were performed to check the integrity of structure. A time history wave response analysis and response spectra seismic analysis was undertaken to assess dynamic behaviour of the platform. A Structural Integrity Management (SIM) Manual was developed for KMT platform life extension including a managed system for archive and retrieval of SIM data, evaluation of structural integrity and fitness for service (development of remedial actions) and risk based inspection program/strategy.

Turrum Phase II Development: MLA Structural Integrity Assessment Customer: Esso, Australia Location: Bass Strait, Australia The structural integrity assessment of Marlin A (MLA) platform was required due to addition of topside facilities and the platform life extension until year 2039. An increase in metocean criteria (e.g. wave inundation) was also considered in conjunction with the additional loads. The topside modifications were included the following: • • • • •
Bridge Landing on the North-West corner of the platform to support the 60 m bridge linking MLA and Marlin B (MLB) Process and utility modification New temporary living quarters in addition to the existing living quarters Brucker upgrades Rig 22 facilities
Since the MLA platform does not meet the requirements of design level check, the reserve strength and reliability assessments were undertaken to develop the strengthening options select report and establish the Risk Based Inspection (RBI) program.
West Tuna Impulsive Analysis and Structural Integrity Assessment Customer: Esso, Australia Location: Bass Strait, Australia An assessment of the West Tuna Module Support Frame (MSF) structure has been undertaken for the impulse loads which replicate the unusual motion events observed on the platform. The characteristic shape of the measured data indicated that the likely cause of the perceived motion is an impulsive load on the South shaft. A dynamic analysis by Doris Engineering provided a calibration to the magnitude and shape of the impulse loading by matching the measured and predicted accelerations in the quarters. A combined CGS, MSF and topsides model developed for the seismic analysis was used as the basis for this assessment. A time history analysis was conducted to estimate the structural response to the prescribed impulse loading. A fatigue model was also developed based on the time history analysis model. The MSF structure from the analysis was used for fitness for service assessment. The numbers of cycles together with applicable stress ranges were established from the time history assessment. The fatigue analysis was then conducted to evaluate the fatigue damage to the MSF joints.
Yolla Mid Life Enhancement Project: Platform Integrity Assessment Customer: Origin Energy, Australia Location: Bass Strait, Australia The structural integrity assessment of Yolla platform was required due to addition of topside facilities. The topside modifications were included the following: • New Accommodation and Utility Modules • Temporary Personnel Transfer Bridge Landing • Grillage for the Drilling Rig • Construction Crane • Compressor and Pump Units • Alternative Muster Area Platform In-place Strength, Fatigue and Seismic analyses were performed to check the integrity of structure during and after MLE project. A time history wave response analysis and response spectra seismic analysis was undertaken to assess dynamic behavior of the platform due to the dditional topside weight. A FE analysis of the topside hull structures was carried out as part of the integrity assessment of the platform. Strengthening and modification options study was also developed and the selected strengthening and modification option was detailed.
