WorleyParsons Project Phases

Floating Production Systems Capability & Experience | 5

Capability Overview WorleyParsons holds an comprehensive capability in all areas of floating production systems and utilises world class execution skills in all phases of project delivery. Floating Production Storage and Offloading (FPSO) WorleyParsons specializes in “fit-for-purpose” design for FPSO projects. The FPS team have an extensive track record in managing design that incorporates regulatory compliance, severe metocean criteria and operational requirements. Value is created through optimizing hull sizing, stability, motions and seakeeping. Interface management and risk management are at the forefront of all our design, planning and execution activities.s.

Floating Liquefied Natural Gas (FLNG) The rapidly emerging FLNG market seeks to monetize resources from stranded and remote gas fields . FLNG offers several development, operations and commercial advantages, including offshore access, cost savings from onshore infrastructure and pipelines, and a potentially shorter construction schedule. WorleyParsons is well positioned to support customers. Our technology neutral approach ensures an optimal solution for the customer. WorleyParsons’ extensive experience in marinization and modularization, together with offloading and containment systems ensures risks are known and quantified early in the conceptual design phase. Through our relationship with Norway’s Kanfa Aragon we can offer field-specific FEED engineering, detailed design, procurement and commissioning of FLNG topside facilities.

Floating Storage and Regasification Units (FSRU) Our experienced team has played key roles in a variety of LNG terminal/ regasification projects including those with novel concepts, such as LNG storage and regasification units (FSRUs) and side-by-side/tandem LNG transfer from/to an LNG carrier. WorleyParsons understands the demands, scale and integration requirements of developing LNG regasification facilities. Our specific service areas include hull integration of regas process equipment and vessel hydrodynamic analysis for design of mooring systems. WorleyParsons supports customers in determining optimal contracting strategy pathways by providing a comprehensive understanding of the CAPEX, OPEX and lifecycle costs. Through our alliance with Sofregaz, we have also developed marinized and offshore maintenance-friendly regas modules for use on FSRUs and we can offer these to our customers on a lumps sum EPC basis.

Semi-submersibles Our team has completed more than 20 successful semi-submersible projects including three new-build, designs. Our capability covers all design phases and includes hull and deck, process topsides, mooring systems and riser systems. This capability extends to construction support, transportation analysis and operational brownfield support services. The team uses a unique and proprietary integrated design suite that links the hydrodynamic load generation models with the structure models and then with the 3D design models. WorleyParsons is recognized for innovative design including dry tree and CentrePontoon (CP) semi-submersibles. CP semis offer a very efficient hull structural design, by comparison to conventional semis. Our customers have access to a range of six standard CP semi-submersible designs.

Tension Leg Platforms (TLPs) WorleyParsons is the world leader in TLP design, having been instrumental in the design of sixteen of the twenty-one currently sanctioned tension leg platforms. Our hull configuration is considered to be the most efficient structural design in the market and we are recognized for setting new industry standards. The SelfStabilised Integrated Platform (SSIP) TLP is a good example of this. The SSIP TLP blends standard TLP design with the MOSES porch which allows quayside topsides installation. Services extend beyond engineering into the construction and installation phases of projects. In-service inspection is also provided resulting in key roles in maintenance and expansions programs.

Spars WorleyParsons is a global leader in spar design, having participated in major portions of the designs of Genesis, Diana, Medusa, Devil’s Tower, Front Runner, Constitution, Red Hawk, Holstein, Mad Dog and Mirage spars. We are the only engineer with execution experience in all three spar types and have designed spars to record setting water depths. We are very proud of the fact that we currently hold the world record for water depth with the Perdidio spar.
