Low-profile Japanese shipowner Nissen Kaiun has returned to South Korea's Hyundai Heavy Industries for a trio of VLGC newbuildings.

Nissen’s latest order brings the tally of 84,000-cbm vessels it has under construction at HHI to four, while two other VLGCs being built in Japan take its total newbuilding haul for vessels of this size to six.

A gas player said Nissen signed up for the latest trio late last year but the order went unreported.
