Seri Everest, the first in a series of three 98,000 cbm Very Large Ethane Carriers (VLECs) built at Samsung Heavy Industries Co., Ltd. (SHI) and delivered to MISC Berhad on October 30, 2020. Seri Everest is the first from a series of six VLECs that MISC purchased in July 2020. As a second generation VLEC, Seri Everest is one of the largest vessels of its kind in the world.

With the delivery of MISC’s first VLEC – Seri Everest, she has set a new benchmark in the ethane market. Seri Everest has the capacity of transporting ethane in large volumes over long distances, while ensuring the highest level of safety and reliability. At present, Seri Everest is the largest VLEC operating in the market, and MISC will be the largest transporter of Ethane in the world upon delivery of all her sister vessels, in this series. Seri Everest incorporates the latest state-of-the art technologies in various forms including multi-gas deep well pumps, reliquification plants, and Boil-off gas (BOG) compressors that increases the efficiency of the GTT’s Mark III Membrane Type cargo containment system and effectively reduces the vapor pressure in the cargo tanks. This VLEC is powered by a MAN B&W 7G60ME-C9.5-GIE Gas Injection Ethane engine, complemented with the latest Pump Vaporizer Unit (PVU), making it one of the very few vessels in the world with ethane burning capability. 

Seri Everest was also delivered with LNG Ready notation by ABS, proving the robustness of the vessel. Staying true to the owner’s agenda towards a decarbonized future, Seri Everest was built with green technology features which include energy efficiency, emission reductions and biodiversity management. These features also include the installation of the Selective Catalytic Reduction (SCR) system for the main engine and diesel generator to comply with the latest IMO Tier III requirements. The VLEC is also equipped with IMO and USCG approved, Electrolysis indirect type, ballast water treatment plant complying with the requirement of IMO MEPC 169(57) & 174(58 and built in accordance with International Convention for Sea and Environmentally Sound Recycling of Ships to ensure proper end-of-life disposal.

Seri Everest is chartered to STL for a firm period of 15 years and is managed by Eaglestar Shipmanagement Gas (S) Pte. Ltd. As the second generation VLEC, Seri Everest and the other five VLECs are the largest vessels of its kind in the world. The VLEC’s serve as a more economical and viable solution for large-scale ethane transportation with more than 98,000 cbm of total cargo capacity. Korean shipyards Samsung Heavy Industries and Hyundai Heavy Industries, are building the remainder of the five VLEC’s scheduled to be delivered in the first half of 2021.
