HHI given AiP from DNV GL for LPG carrier

Johan Petter Tutturen, DNV GL business director gas carriers, presented the AiP certificate for the 91,000m³ dual fuel vessel design to Hyung Kwan Kim, executive vice president and chief technology officer at HHI, at the Gastech trade fair in Houston, Texas.

“The latest AIP yet again proves HHI’s innovation power in the LPG carrier market,” said Hyung Kwan Kim. “We are particularly proud to receive this certificate as the carrier design lays the groundwork for constructing the largest-sized vessels using LPG cargo as a fuel today.”

With shipping companies facing ever stricter emission rules, LNG is the alternative fuel of choice for more than 350 vessels worldwide, while LPG as a ship fuel has been adopted by only a limited number of vessels as yet. However, LPG could be a compelling option as its energy and capital costs are relatively low, whilst also serving as a possible precursor to run on zero-carbon ammonia. Furthermore, an LPG dual fuel vessel design with an engine mounted shaft generator can minimise cargo loss and decrease operational costs as well as CO2 emissions by reducing running hours of diesel generator engines burning fuel oil. “HHI’s innovative design is doing a great deal to expand the industry’s operational experience with LPG technology,” said Johan Petter Tutturen.

The award ceremony in Houston is the culmination of a series of in-depth joint research projects on LPG technology by HHI and DNV GL.
