LNG Shipping Stocks — The Guide to the Gas Carrier Cycle

LNG vs LPG — What's the Difference?

LNG (Liquefied Natural Gas) and LPG (Liquefied Petroleum Gas) are often confused but are transported on different vessel types:

• LNG is natural gas (primarily methane) cooled to -162°C to become liquid for transport. LNG carriers are among the largest and most technologically complex vessels in the world, typically ranging from 140,000 to 180,000 cubic metres capacity.
• LPG consists of propane and butane — byproducts of natural gas processing and oil refining. LPG carriers (VLGCs — Very Large Gas Carriers) transport these at -50°C and are smaller than LNG carriers.

Both segments are listed on Oslo Børs through different companies: BW LPG and Avance Gas are the primary LPG carriers; Höegh LNG Partners and Golar LNG have had Oslo Børs listings in the LNG space.

The LNG Market Structure

Unlike crude oil or dry bulk, LNG shipping is predominantly contract-based rather than spot-traded. Large LNG carriers are often chartered for 15–25 years to underpin the financing of new liquefaction projects. This means LNG shipping is less volatile than other shipping segments — but also means cycle turns happen more slowly, driven by contract renewals and new project developments rather than short-term rate swings.

The spot LNG carrier market does exist and can be extremely volatile — particularly during periods of energy market stress (the 2021–2022 European energy crisis drove spot LNG carrier rates to extraordinary highs).

The LPG Cycle — More Volatile, Shorter Cycles

The LPG shipping market (primarily the VLGC segment) operates more like crude tankers — spot-rate driven, with strong cycles. BW LPG, listed on Oslo Børs, is one of the world's largest VLGC operators and provides the most accessible listed exposure to this cycle.

Key cycle drivers for LPG shipping:

• US LPG export volumes (the US shale boom dramatically increased LPG exports)
• Middle East OPEC production levels (Saudi Arabia and UAE are major LPG exporters)
• Asian import demand, particularly India and China
• VLGC order book and fleet utilisation

The Long-Term Structural Case for LNG

The energy transition is, paradoxically, a long-term positive for LNG shipping. As coal-dependent economies in Asia seek to reduce emissions, natural gas is the bridge fuel — cleaner than coal, more reliable than intermittent renewables. The construction of new LNG import terminals in Europe (following Russian gas disruptions) and Asia is creating decade-long demand for new LNG carriers.

The LNG carrier order book has been growing — indicating shipyards and operators are anticipating this structural demand growth. This reduces the short-term supply tightness that would otherwise drive rates higher, but supports the long-term business case for established operators with modern fleets.
