BS continues to review novel gas transport and storage technology with Approval In Principle (AIP) given to Torp Technology’s HiLoad LNG Regas units. Read more.

The TORP HiLoad LNG Regas unit is a floating L-shaped mechanism that locks directly onto a vessel carrying liquefied natural gas (LNG). Once attached the HiLoad unit converts the LNG into vapor and injects it in to underwater pipelines to supply the gas to shore. TORP’s HiLoad technology eliminates the need for a large marine storage structure i.e. a terminal or above ground storage tanks at ports.

According to ABS’ Senior Staff Consultant Phil Rynn, who reviewed the proprietary regasification technology, the HiLoad system can connect to any LNG carrier and can regasify at a rate of 1.4 Bcf/day.

Rynn says ABS reviewed the technology using the ABS Guidance Notes on Review and Approval of Novel Concepts and other applicable ABS Rules.

The HiLoad uses a patented friction based attachment system that is basically rubber suction cups to minimize relative motion between the carrier and the terminal. Rynn says one of the critical concerns for loading/offloading LNG is the relative motions between the carrier and the floating offshore terminal.

"Transfer of LNG—at subzero temperatures—through a loading hose presents industry with a technological challenge. Based on our review, the HiLoad technology is appropriate for reliable and flexible transfer of LNG offshore,” he added.

Currently an offshore receiving and regasification terminal proposed for the Gulf of Mexico has selected HiLoad technology as well as a terminal planned for off the coast of Southern California.
