YM WELLBEING is a large containership built by Imabari Shipbuilding in Japan in 2018, commercially operated by Yang Ming Marine Transport.
At more than 366 metres long, approximately 152,000 GT and 146,749 tonnes deadweight, the vessel forms part of the generation of large 14,000-TEU ships introduced to the main East–West container trades during the late 2010s.
One significant change has taken place since the original PiraeuShips entry: YM WELLBEING no longer sails under the Panama flag.
She transferred to the:
Singapore flag
and remains fully active in the Yang Ming liner network in 2026.
Name: YM WELLBEING
IMO: 9820908
Current MMSI: 563226100
Current Call Sign: 9V9755
Type: Container Ship
Current Flag: Singapore
Built: 2018
Builder: Imabari Shipbuilding, Japan
Owner: Yang Ming Marine Transport Corp.
Operator: Yang Ming
Class: ABS
Current Gross Tonnage: approx. 152,017 GT
Earlier Published GT: approx. 151,451 GT / rounded 150,000 GT
Deadweight: 146,749 t
Length Overall: 366.44 m

Draught: approx. 15.5 m
Container Capacity: 14,220 TEU
Current Status: Active.
YM WELLBEING was completed in:
2018
by:
Imabari Shipbuilding.
Historical photographic records identify the vessel with the company's Mihara / Hiroshima-area facilities.
At delivery, she joined a group of very large containerships chartered or employed in Yang Ming's global network.
Current liner data gives capacity of:
14,220 TEU.
This makes YM WELLBEING substantially larger than the Panamax and post-Panamax ships that dominated international container shipping only a decade earlier.
She measures:
366.4 metres
in length and:
51.2 metres
in beam.
The original PiraeuShips article simply rounded the vessel's size to:
150,000 GT.
Older ship databases often give:
151,451 GT,
while current insurance and registry information gives approximately:
152,017 GT.
These variations reflect different updated registry datasets rather than a meaningful change in the physical size of the vessel.
When PiraeuShips documented the ship, YM WELLBEING sailed under the:
Panama flag.
Her original radio identity included:
MMSI 355563000
and:
Call Sign HPFB.
The vessel subsequently transferred to:
Singapore.
Current identification is:
MMSI 563226100
Call Sign 9V9755.
Gard's current insurance records identify:
Yang Ming Marine Transport Corporation
as owner and show valid certificates extending into:
2027.
YM WELLBEING has a documented Piraeus history.
She was photographed at:
Piraeus in January 2019,
only months after entering service.
PiraeuShips later published the dedicated:
YM WELLBEING – IMO 9820908
entry in:
June 2020.
The recording therefore dates from the ship's original Panama-flagged period.
YM WELLBEING remains fully active in:
2026.
Current liner schedules show her operating in Yang Ming's major alliance network alongside:
ONE
and:
HMM.
September 2026 records placed her on the:
Far East Pacific 2
service, while later schedules continue into November.
YM WELLBEING was recorded by PiraeuShips during the early Panama-flagged phase of a large modern containership career. Built by Imabari Shipbuilding in Japan in 2018, the 366-metre vessel has a nominal capacity of approximately 14,220 TEU and a deadweight of 146,749 tonnes. Since the original PiraeuShips entry, YM WELLBEING has transferred to the Singapore flag and today carries MMSI 563226100 and call sign 9V9755, while remaining associated with Yang Ming Marine Transport. Still fully active in 2026 on major international alliance services, the ship gives the PiraeuShips archive a useful record of her original registry and early operating configuration.

YM INCREMENT is a Taiwan-built containership completed in 2006 for Yang Ming Marine Transport Corporation and one of a series of compact regional container vessels constructed by CSBC at Keelung.
At approximately 172 metres in length, 16,488 GT and 22,027 tonnes deadweight, the vessel was designed primarily for regional Asian and feeder services rather than the intercontinental mega-container trades.
Unlike many containerships of her age, YM INCREMENT has retained both her original name and her connection with Yang Ming throughout two decades of operation.
An important recent change concerns her registry: after many years under the Liberian flag, YM INCREMENT transferred to the Singapore flag in 2025.
She remains fully active in 2026, operating Yang Ming's intra-Asian liner network.
Name: YM INCREMENT
IMO: 9319143
Current MMSI: 563250800
Current Call Sign: 9V9750
Type: Container Ship
Current Flag: Singapore
Built: 2006
Builder: CSBC Corporation, Keelung, Taiwan
Yard Number: H852
Owner / Manager: Yang Ming Marine Transport Corporation
Class: DNV
Gross Tonnage: 16,488 GT
Net Tonnage: 7,615 NT
Deadweight: 22,027 t
Length Overall: 172.10 m
Beam: 27.30–27.35 m
Maximum Draught: approx. 9.5 m
Container Capacity: approx. 1,799–1,805 TEU
Main Engine: MAN B&W 7S60MC-C
Historical Engine Output: approx. 21,490 PS / 15,800 kW
Current Status: Active
YM INCREMENT was constructed by:
CSBC Corporation at Keelung, Taiwan
as yard number:
H852.
She formed part of a series of similar Yang Ming containerships constructed at CSBC during the mid-2000s.
Related vessels included ships such as:
YM INTELLIGENT
YM IDEALS
YM IMMENSE
and:
YM INCEPTION.
The series shared similar dimensions, machinery and container capacity.
Current vessel databases give a nominal container capacity of approximately:
1,800 TEU.
This places YM INCREMENT in a very different sector from Yang Ming's modern fleet of 13,000–15,500 TEU mainline vessels.
Her smaller size remains useful for:
regional services,
secondary ports,
intra-Asian routes,
and feeder connections between major container hubs.
The vessel is powered by a:
MAN B&W 7S60MC-C
low-speed diesel engine.
Historical technical information gives an output of approximately:
21,490 PS,
or around:
15.8 MW.
The machinery was well suited to the relatively fast regional liner schedules for which ships of this generation were designed.
One of the most interesting characteristics of YM INCREMENT is the continuity of her commercial career.
The ship has remained associated with:
Yang Ming Marine Transport Corporation
since construction.
She has also retained:
YM INCREMENT
as her name throughout approximately twenty years of service.
Many containerships of a similar age have passed between owners, charterers and multiple identities.
YM INCREMENT is therefore comparatively straightforward historically.
For most of her career the vessel sailed under the:
Liberian flag.
During this period her radio identity included:
MMSI 636012794
and:
Call Sign A8HW9.
This was the configuration in which the ship was recorded in the original PiraeuShips article.
YM INCREMENT has a clearly documented connection with:
Piraeus.
The ship was photographed at:
Perama on 6 August 2015.
At the time she remained under the Liberian flag and was already around nine years old.
The visit demonstrates that her employment was not always limited to the Asian region during the earlier stages of her career.
PiraeuShips published the dedicated:
YM INCREMENT – IMO 9319143
entry in:
February 2017.
The original vessel data correctly recorded:
16,488 GT
22,027 DWT
CSBC Keelung
Liberian flag
and:
Yang Ming Marine Transport as manager and owner.
A major administrative change occurred in:
February 2025.
YM INCREMENT transferred to the:
Singapore flag.
Her new radio identity became:
MMSI 563250800
Call Sign 9V9750.
The ship nevertheless retained:
the same name
and:
the same Yang Ming commercial identity.
YM INCREMENT remains fully operational in 2026.
Yang Ming's own current schedules continue to list IMO 9319143 on the:
JTS – Japan–Taiwan–South China Express
service.
Ports on this network include:
Nagoya
Tokyo
Yokohama
Keelung
Kaohsiung
Xiamen
Shenzhen
Port Klang
and:
Singapore.
The vessel was still appearing in Yang Ming's official schedules in September 2026.
By 2026, YM INCREMENT has completed approximately:
20 years of commercial operation.
Rather than being displaced completely by the dramatic growth in containership size, she has moved naturally toward the regional trades where an approximately 1,800-TEU ship remains useful.
This illustrates the continuing importance of smaller container tonnage within global liner networks.
YM INCREMENT was recorded by PiraeuShips during the vessel's long association with Yang Ming Marine Transport Corporation. Built by CSBC at Keelung, Taiwan, in 2006, the approximately 1,800-TEU containership spent most of her career under the Liberian flag and was documented at Perama several years before the dedicated PiraeuShips entry appeared in February 2017. A major registry change took place in 2025 when YM INCREMENT transferred to the Singapore flag, receiving MMSI 563250800 and call sign 9V9750 while retaining both her original name and Yang Ming management. Still fully active in 2026 on the company's Japan–Taiwan–South China Express service, the vessel represents a durable generation of medium-sized regional containerships that continue to perform an important role two decades after construction.
