Hyundai Heavy Industries wins the third VLGC order since the beginning of this year.
Solvang has splashed out on another VLGC at the Korean yard.
The Oslo-listed company has exercised an option for a 84,000-cbm vessel at Hyundai.
Solvang did not reveal a price for its latest acquisition but the company penned an order for its first VLGC at the same yard in June last year at a reported price of $77m.
Both vessels are scheduled to hit the water in the second half of 2013. Solvang will be managing owner of each vessel, with a 15% stake in the first and 20% in the second.
Meanwhile, Hyundai won two more VLGC orders earlier this year from SK Shipping and Pertamina.
