Norgas has relations with both LNG producers and traders around the world and can develop LNG volumes for its clients based on location and demand. We have also developed our own Small Scale LNG liquefaction concept for shallow offshore fields offering a fast-track, flexible and weather resistant solution.
The Norgas SSLNG Liquefaction Solution for Shallow Offshore Fields Fast Track, Flexible and Weather Resistant
- Norgas has developed a concept for enabling liquefaction and storage of LNG by retrofit of an existing Jack-Up rig, positioned in stranded, shallow water gas fields, providing the following benefits:
- Reduced lead-time compared to conventional FLNG solution – 15-24 months.
- Faster mobilization and requires no site preparation or construction.
- Weather resistant solution utilizing existing infrastructure available at low cost (the Jack-Up Rig).
- Can be combined with the Norgas MINI LNG vessel, providing a full solution for smaller gas fields from liquefaction to distribution to end users.
- Owing to the modular nature of the liquefaction plant as well as the tanks, the components can be located on a single or multiple rig(s) depending on the throughput and liquefaction volumes and thus is a scalable and flexible solution.
- The liquefied LNG can be stored and subsequently loaded on a feeder vessel for transportation to a shore-based consumer installation in the nearby coastal region, thereby increasing the outreach of the gas field.
- This solution can be retrofitted on an existing Jack up rig at a suitable yard where the equipment is available and is then subsequently towed to position.
- A multi buoy mooring arrangement in conjunction with the SSLNG vessel’s thrusters or dynamic
positioning capability would enable the SSLNG vessel to position itself safely alongside the self-elevating platform without loading the rig stations.
- In addition to smaller stranded gas fields, the solution can be utilized to capture and utilize flare gas
at shallow offshore oil and gas production sites.
