Optimisation of Ethane Transport: A Dedicated Technology by GTT
The demand for ethane transport is increasing, and is expected to grow steadily over the coming years. In the case that vessel flexibility of vessels capable of also carrying different types of cargo, such as LNG (Liquefied Natural Gas), is not required, GTT has developed a membrane technology specifically designed for ethane transportation, leveraging the proven experience of its Mark III system.
A Technology Adapted to Ethane Specificities
The containment system developed by GTT is based on the well-established Mark III technology, which has demonstrated extensive reliability at sea. However, unlike versions designed for LNG transportation, this new solution is exclusively dedicated to ethane. One of the key differences between ethane and LNG lies in their boiling points. As Ethane has a higher boiling point compared LNG, it is possible to reduce the insulation thickness. This adaptation results in a significant cost reduction compared to the standard Mark III technology. Additionally, decreasing the insulation thickness increases cargo capacity by more than 1,000 m3, thereby enhancing transportation efficiency. As a result, Mark III technology adapted to Very Large Ethane Carriers (VLECs) increases the capacity of these vessels from 100,000 m3 to 101,000 m3 on the current largest capacity VLEC.
An Optimal Investment Strategy
The current market for ethane carriers predominantly involves vessels with a capacity of approximately 100,000 m3. In contrast, typical LNG cargo volumes traded are around 174,000 m3. Consequently, using a 100,000 m3 vessel designed for LNG transport may not be the most efficient or cost-effective solution. In this context, dedicating this capacity exclusively to ethane transportation is a strategic and relevant investment. It should also be noted that this « ethane » design is also capable of transporting LPG, Ethylene, butane, etc.
With its Mark III technology dedicated to VLECs and Ultra Large Ethane Carriers (ULECs) with capacities of up to 150,000 m3, GTT reaffirms its commitment to providing innovative, cost-effective solutions tailored to the evolving needs of the liquefied gas transport sector.
