JGC Global to Develop Standard Package for FLNG Plant Design

JGC Global Corporation (Representative Director and President: Shoji Yamada), the overseas EPC business unit of JGC Holdings Corporation (Representative Director, Chairman and CEO: Masayuki Sato), announced the start of development for a 'standard package' (standardized specifications) for the design of offshore FLNG (Floating Liquefied Natural Gas) production, storage, and offloading plants. This initiative aims to improve design efficiency and accelerate project execution and delivery for FLNG projects.

This standard package is being developed in collaboration with Honeywell, a world-leading process licensor, with completion expected within fiscal year 2026. This has the potential to shorten the time from order to delivery by over a year, depending on project and client requirements.

Traditionally, FLNG plant design has been conducted on a bespoke basis in coordination with licensors and shipowners to meet client demands. While this approach allows for detailed responses to individual needs, it consumes significant time and effort during the design phase, often leading to increased costs and longer delivery schedules.

In the newly developed standard package, we will establish high-quality standard specifications in advance through collaboration with the licensor, significantly reducing post-order design work and achieving shorter delivery times and lower costs. Furthermore, utilizing standardized specifications enables highly reusable module design and construction.

This standard package adopts Honeywell’s Dual Mixed Refrigerant (AP DMR™) process, which has a long track record of operation worldwide and excels in the balance of efficiency, flexibility, and compactness. Honeywell possesses key process technologies such as APCI LNG and UOP, with the strength to provide end-to-end licensing across the LNG value chain from upstream to downstream. We have integrated this with JGC Global’s engineering capabilities, which include extensive experience with some of the world’s largest FLNG projects, and our unique module design technology that pursues high processing capacity within limited floating space.

By doing so, we ensure LNG purification capacity capable of handling diverse gas fields, while simultaneously achieving shorter construction periods through module construction methods and accelerating project delivery, ultimately improving work efficiency.

In recent years, against the backdrop of rising global energy demand and diversification of procurement sources, there is growing demand for small-to-mid-scale FLNG plants that are less subject to regional limitations. Furthermore, there is an increasing request from clients for speed and schedule certainty in projects, and expectations for a standard package are rising. This package maximizes the advantages of FLNG plants, which can be applied even in regions where onshore plant construction is difficult due to geopolitical or geographical constraints, and contributes to the rapid development of small-to-mid-scale gas fields and the early launch of energy supply.

These efforts are part of the sustainable strengthening of competitiveness in the comprehensive engineering business, which is a key strategy in JGC HD’s newly formulated medium-term management plan, 'Building a Sustainable Planetary Infrastructure 2030.' By strengthening collaboration with external partners and incorporating design focused on cost and delivery, we will flexibly respond to the diverse needs of our clients across the entire EPC value chain.
