Comparison
WinGD and MAN engines in the LNG fleet
How many two-stroke dual-fuel LNG ships, in service and on order, name each engine maker, and which yards use which. A count of ships, not a verdict on engines.
One family of ships, and a maker is named only there
The tracker names an engine maker for two-stroke dual-fuel ships alone: 338 of 822 operating ships and 250 of 364 under construction. Steam-turbine and four-stroke ships carry no maker, so they are outside this page; for how the three propulsion families compare see propulsion types.
Operating ships and ships under construction are in separate columns and never added. A two-stroke ship whose maker the tracker does not name is shown as “Not reported”.
Ships by engine maker
Two-stroke dual-fuel ships only, by the maker the tracker names.
| Engine maker | Operating ships | Share of operating | Under construction | Share of under construction |
|---|---|---|---|---|
| WinGD | 189 | 56% | 182 | 73% |
| MAN Energy Solutions | 149 | 44% | 68 | 27% |
| All two-stroke dual-fuel ships | 338 | 250 |
Shares are of the two-stroke ships in that status. These are ships, not engines. For what the engines are, read the guide to two-stroke propulsion.
Which yards use which
Two-stroke ships by the yard that built or is building them, operating and under construction counted together here only to show each yard's practice.
| Yard | WinGD | MAN Energy Solutions | Not reported |
|---|---|---|---|
| HD Hyundai Heavy Industries | 123 | 37 | — |
| Hanwha Ocean | 35 | 102 | — |
| Samsung Heavy Industries | 79 | 57 | — |
| Hudong-Zhonghua Shipbuilding | 84 | — | — |
| HD Hyundai Samho | 22 | 9 | — |
| DSIC (Dalian Shipbuilding Industry Co) | 17 | — | — |
| Jiangnan Shipyard | 10 | — | — |
| China Merchants Heavy Industries | — | 8 | — |
| Yangzijiang Shipbuilding | — | 2 | — |
| Imabari Shipbuilding | — | 2 | — |
| Jiangsu YiXiang Shipbuilding | 1 | — | — |
11 yards name at least one maker. For the yards themselves see where ships are built.
Common questions
Each answer stands on its own.
- Which company makes the engines in most two-stroke LNG ships?
- Among operating two-stroke dual-fuel ships, 189 name WinGD and 149 name MAN Energy Solutions, out of 338. Among those under construction it is 182 WinGD and 68 MAN, out of 250. These are counts of ships, and the two groups are kept apart.
- Does the order book favour one maker more than the fleet in service?
- Of the ships that name a maker, WinGD is 56% of those in service and 73% of those under construction; MAN is 44% and 27%. The tracker does not say why, and ships on order are a plan rather than fleet in service.
- Why are steam and diesel-electric ships not in this comparison?
- GEM names an engine maker only for two-stroke dual-fuel ships. Steam turbine and four-stroke diesel-electric ships carry no maker in the tracker, so there is nothing to compare, and the 484 operating ships on other propulsion are outside this page. See propulsion types for those.
- Does this say which engine is better?
- No. It counts ships by the maker the tracker names. Fuel use, reliability and cost are not in the data, and a yard may choose an engine for reasons the tracker does not record.
