CIMC SOE launches new LNG bunkering vessel for Avenir

Nantong CIMC Sinopacific Offshore and Engineering has launched the Avenir Allegiance, expanding the firm's liquefied natural gas fleet.

By the CEII Desk, from reporting by LNG Prime

Key points

  • CIMC SOE launched the Avenir Allegiance, the second vessel in Avenir LNG's latest program.
  • The 20,000-cbm vessel is scheduled for delivery in the first quarter of 2027.
  • The ship will serve ExxonMobil affiliate SeaRiver Maritime under a multi-year charter.

What happened

LNG Prime reported that Nantong CIMC Sinopacific Offshore and Engineering in China has launched an advanced liquefied natural gas bunkering and supply vessel. The ship, named Avenir Allegiance with Hull Number S1124, forms part of Avenir LNG's expansion efforts. The company is backed by Norwegian firm Stolt-Nielsen and Japanese enterprise NYK.

This build follows an order placed in 2024 for a pair of 20,000-cubic-metre supply units. SeaRiver Maritime, the marine transportation division of ExxonMobil, secured the vessel through a multi-year time charter agreement finalized in October 2025. Delivery to the charterer is anticipated during the initial three months of 2027.

Construction progress continues on earlier orders from the same batch. The initial 20,000-cbm vessel entered the water earlier this year in July and is slated to support Vitol on a seven-year agreement, featuring potential extensions reaching ten years in total. Fleet integration for that first unit is expected before the end of 2026.

Design specifications for these carriers include a length of 160 metres and a breadth of 25 metres, alongside a target operational speed of 15.5 knots. Propulsion relies on a WinGD dual-fuel main engine configuration incorporating iCER technology to manage emissions and efficiency.

Why it matters

Developments in global liquefied natural gas bunkering infrastructure directly influence maritime logistics and cleaner fuel adoption across international shipping lanes. While this specific asset is deployed outside African waters, the expansion of global bunkering capacity signals steady momentum in the LNG marine fuel supply chain. For African energy producers and exporters, particularly nations investing heavily in gas monetization like Nigeria, robust international demand for LNG as a marine transition fuel underpins long-term project viability. As global shipping operators secure multi-year supply arrangements with majors like ExxonMobil, African suppliers monitoring export markets observe how downstream marine infrastructure scales to match growing cleaner fuel requirements.

Context from CEII

Gas is the flexible backbone of many grids and the designated transition fuel in many national plans, from LNG trade to domestic LPG and CNG. Supply security and pricing drive both power reliability and emissions.

3.0% of electricity in China came from gas in 2024
