Kawasaki Heavy Industries announced the delivery of the 84,000 m3 capacity liquefied petroleum gas (LPG) carrier CRYSTAL TRINITY

January 28, 2022

Kawasaki Heavy Industries announced it has delivered the 84,000 m³ capacity liquefied petroleum gas carrier CRYSTAL TRINITY for KUMIAI NAVIGATION . This is the 65th LPG carrier built by the company.

This vessel is a dual-fuel LPG carrier using LPG and low-sulfur fuel oil, and Kawasaki’s second 84,000 m³ LPG carrier adopting a dual-fuel main engine.

In recent years, in order to effectively reduce emissions of greenhouse gases from international shipping, more vessels are adopting liquefied gases as an alternative to heavy fuel oil on a global scale. This very large LPG carrier is powered by LPG, which reduces greenhouse gas emissions and is expected to significantly reduce environmental impact. It is the fruit of the Kawasaki Group’s accumulated knowledge in building LPG and liquefied natural gas (LNG) carriers, and LNG-fueled vessels.

Kawasaki plans to develop and build more LPG-fueled LPG carriers and other commercial vessels that meet environmental standards, as well as to develop and offer other eco-friendly marine technologies, to contribute to the establishment of a low-carbon/decarbonized society. These products include vessels for transporting liquefied hydrogen, considered to be the next-generation energy source.

Features

This LPG carrier operates using both LPG and low-sulfur fuel oil. Use of LPG as fuel greatly reduces emission volumes of sulfur oxides (SOx), CO₂ and other pollutants compared with use of marine fuel oil. In this way, the new vessel will meet SOx emission standards*¹ which were strengthened in January 2020, and EEDI*² Phase 3 regulations which will further strengthen CO₂ emission standards in 2022.
In order to satisfy restrictions on NOx TierⅢ controls*³ emissions which is implemented by the International Maritime Organization (IMO), the main engine and generator are equipped with a Selective catalytic reduction (SCR) System, An exhaust gas purification system to reduce NOx, which allows the ship to navigate in Emission Control Area (ECA).
Installation of LPG fuel tanks on the ship’s upper deck makes it possible to load fuel-use LPG separate from the ship’s cargo LPG. Moreover, a piping system connecting the LPG fuel tanks and LPG cargo tanks enables transferring of extra LPG to the LPG fuel tanks if necessary.
This vessel adopts the Kawasaki rudder bulb system with fins (RBS-F) and the semi-duct system with contra fins (SDS-F) contribute to reducing fuel consumption.
