FLNG is a technological response to the commercial challenge of delivering offshore gas resources to distant markets competitively. For remote resources, it may simplify overall supply-chain construction vs. land-based LNG plants. The commercial context set by the market price and alternative supply chain options limits the space for technical solutions. Patterns emerging from risked economic comparison of given FLNG options against pipe-to-shore alternatives will help determine whether FLNG is a niche or a mainstream options and whether large, mid-sized or small-scale projects eventually predominate. This session will examine the market context for post-2020 LNG projects and explore how FLNG fits into this evolving offshore gas development landscape. It will also examine issues impacting the selection of an FLNG scheme, while providing a business context for the workshop.
This session will explore the key process engineering and topsides facilities choices for FLNG. While the process engineering is not dissimilar to FPSO or land based gas processes, there are aspects which are more complex in FLNG applications. Topics to be covered include: acid gas removal, heavy hydrocarbon removal, dehydration system, MEG regeneration, liquid/water management. The selection of liquefaction technology will be discussed.
FLNG poses unique engineering and operational issues mostly driven by the “floating” component of FLNG. This session will explore the engineering associated in the design of hulls, turrets, moorings and cargo containment. It will cover close-coupling to subsea systems and topsides. Offloading systems will be explored including LNG side-by-side and tandem offloading.
FLNG presents unique challenges for process safety and risk mitigation due to the combination of a limited topsides footprint, process complexity and a need to remain on station during extreme weather conditions. Strategies for layouts to including blast walls, process module safety gaps and living quarters will be discussed. Key to the design and operability is the reliable prediction of extreme weather conditions and their operational impacts. The level of technological development of these prediction methods, their use and limitations will be discussed. Enveloping these design and operational decisions is the safety case and the regulatory environment. The regulatory environment of Floating LNG solutions is as novel as the solution itself and as such there is not yet a norm. Speakers will discuss current and future expected practices.
Over the last decades, the industry has matured the technology and systems associated with the surveillance, operation and maintenance of onshore LNG plants, LNG shipping, offshore production and FPSO facilities. FLNG operations, while not yet “live”, will nonetheless benefit from this large available knowledge base, although it will have some unique challenges. This session will examine how to ensure safe, robust and efficient operations. It will cover how the operations and maintenance requirements are embedded into FLNG designs and how operational readiness is anticipated by the operators.Various topics will be discussed such as commissioning & start-up, safety and availability, inspection maintenance repair, training & competency, organisation and remote operations.
Floating LNG is stretching the capacity of the industry when it comes to execution. recognising the complexity of a FLNG unit, technically, commercially, contractually, and operationally. This session will explore how to challenge accepted execution schemes when it comes to contracting strategies and risk sharing, how main shipyards have adapted their traditional procedures to this new market, which new players could be considered, and how these projects can demonstrate social responsibility to the host country. This session will also question the robustness of cost and schedule associated with FLNG projects, recognising the scarcity of established benchmarks.
A live interactive discussion between key members of the FLNG industry. This panel session will provide an opportunity for questions to be fielded openly from the audience on any aspects of the FLNG value chain, with emphasis on the Australian market, and posed to the panelists for thought, discussion and debate. Audience interaction and engagement will be encouraged to maximise the effectiveness of the session.
New technologies and design approaches will be discussed. New approaches to the analysis and management of sloshing in membrane tanks will be examined, as will the latest developments in LNG offloading systems. The response based design approach for moorings is a new method for which there are no industry standards established. Electrically driven compressors are being proposed for some FLNG concepts. The session will also be used to reflect on the previous two days and develop potential topics for future research and development.
