Ton-up for LNG-burning X-DF engines

Ton-up for LNG-burning X-DF engines
Delivered in January 2018, Gaslog Houston is the first LNGC in the GasLog fleet to be powered by X-DF engines

Winterthur Gas & Diesel (WinGD) has secured an order for its 100th Generation X dual-fuel (X-DF) engine. The milestone contract comes only five years after the launch of the two-stroke, gas-burning propulsion system.

WinGD points out that its X-DF technology has demonstrated, on tests and engines currently in operation, that it offers stable combustion and inherently low nitrogen oxide and greenhouse gas emissions. Other benefits include high overall system efficiencies and reliable and safe gas operation.

GasLog Ltd, one of the early supporters of the X-DF technology, has placed the centennial engine order. The latest additions to the Greek shipowner’s inservice LNG carrier fleet are three 174,000 m3 vessels with X-DF propulsion systems. All three were commissioned earlier this year and each ship is fitted with a pair of 5X72DF main engines.

GasLog also has five LNGCs on order at the Samsung Heavy Industries yard in South Korea and the same machinery has been selected for all five. The 100th X-DF engine will be fitted on one of the two latest additions to this newbuilding list – a 180,000 m3 pair contracted at the start of 2018 and scheduled for 2020 deliveries.

On the occasion of the milestone engine order, GasLog’s chief operations officer Richard Sadler said “When we select an engine for GasLog, the most important considerations are the engines’ contributions to the safety, competitiveness, sustainability and reliability of the vessel for our customers.

“When we selected the X-DF, it was crucial for us to find a dual-fuel engine which could offer all those features for today’s and the future environment. WinGD’s X-DF engines were the choice for our new vessels and we continue to be confident in their low-pressure, dual-fuel technology.”

In his comments WinGD’s vice president of sales and marketing Rolf Stiefel stated “If ever there was confirmation that the shipping industry is embracing LNG as the first choice for IMO-compliant engines, the 100th X-DF engine is proof. Achieving this milestone in July 2018, after only five years, validates the recognition given by customers such as shipyards, vessel owners and operators to its unique benefits.”

The first WinGD DF engine in operation – on the 15,000 dwt, 2016-built product/chemical tanker Ternsund – has now logged over 12,000 running hours while the full X-DF-engined fleet of 13 vessels at sea has accumulated over 100,000 running hours.

Besides strong progress made by the WinGD technology in the LNG carrier market, X-DF engines are increasingly being chosen as the propulsion system for large LNG-powered tanker and container ship newbuilding orders. In 2017 CMA CGM elected to power each of their nine newly contracted, 22,000 TEU container ships with a 12-cylinder X92DF engine.

The CMA CGM vessels will be the largest container ships ever constructed while the X92DF units will be the most powerful dual-fuel engines yet built.
