Abstract: In the 21st century, the inland ships in China have been greatly developed. The large-scale and professional
development trends of ships are obvious, and the overall technical level of ships has been greatly improved.
However, the quality of ships constructed is still evidently poorer than that of inland ships in Europe, the
overall existing ships are not green enough, and the fleet capacity cannot be updated promptly. For the high-
quality development of inland ships, this paper recommends the combination of the upgrading of inland
ships with adjustment, transformation, and updating of ship industry structure, promoting the high-quality
development of inland shipbuilding industry on the supply side, presenting and promoting optimal ship
types, and implementing economic policies to encourage the adjustment of the technical-level structures of
inland ships.
1 INTRODUCTION
Compared to highway and railway transportation,
inland river transportation has the advantages of
large capacity, small land area occupied, low energy
consumption, environmentally friendliness, and low
marginal cost. China has abundant inland river
transportation resources. Since the reform and
opening up, especially since the 21st century, the
inland shipping has developed remarkably, and
played an important role in supporting the economic
and social development of the river basin. In the
future, the high-level inland channels of China will
be doubled to 2.5 km. Instructed by the plan of
forming an inland channel network connecting rivers
to the sea, it is a strategic opportunity to improve the
overall quality and technical level of inland ships, to
make full use of the channel infrastructure capacity,
and to improve the overall benefit of inland river
transportation system.
2 OVERVIEW OF CHINA
INLAND VESSELS
At the end of 2019, China has 119.5 thousand inland
vessels, with a total load of 121 million tons. The
inland rivers are widely distributed. The types of
ships are various, and the sizes are relatively small
in general. 70% of them are small vessels with a
capacity of less than 1000 tons. The economy of
ship transportation has an obvious relationship with
its capacity. The low-cost advantage of inland river
transportation is obvious when the capacity reaches
about 1000 tons. Therefore, ships with a capacity of
1000 tons should be the dominant tools of inland
river transportation. In China, the sum of capacities
of vessels with a capacity of 1000 tons accounts
for about 75% of the total capacity. Therefore, the
following sections focus on the analysis of the
situations of the inland vessels with a capacity of
1000 tons in China.
In the year of 2020, 34.3 thousand inland ships
with a capacity of 1000 tons were located in
China. The total and average loading capacities were
94.05 million and 2738 tons, and the mean ship age
was 9.88 years. The owners of these ships, more
than 4800 enterprises and more than 10000
individuals, are relatively scattered.
In terms of the number of ships with a specific
capacity, the number of ships with a capacity of <
5500 tons accounts for a large proportion of almost
89%, and the number of ships with a capacity of
1000 to 2000 tons accounts for 56%, that of ships
with a capacity of 2000 to 3500 tons accounts for
23%, and that of ships with a capacity of 3500 to
5500 tons accounts for 10%, as shown in the Figure

1. In terms of the total loading capacity, the total
capacity of ships with a capacity of < 5500 tons
accounts for about 66%. Among them, the total
capacities of ships with a capacity of 1000 to 2000,
2000 to 3500, and 3500 to 5500 tons account for
28%, 22%, and 16%, respectively, as shown in the
Figure 2.
Figure 1: Proportions of numbers of inland ships with a
capacity of ≥ 1000 tons.
Figure 2: Proportions of total capacities of inland ships
with specific capacities of ≥ 1000 tons.
In terms of the ship age, among the inland
vessels with a capacity of 1000 tons, 16.6
thousand ships, with a total capacity of 4127 million
tons, were built before September 1, 2011, as shown
in the Figure 3. The number and capacity account
for 53.04% and 47.76% of the total values. 715 old
ships with an age of ≥ 18 years, with a total capacity
of 1.31 million tons, account for 2% and 1.5% of the
total values, respectively. 78 special-overhaul ships
have an age of over 29 years, with a total capacity of
150 thousand tons. Most of the inland ships were
built in 2009-2015, accounting for 70% in number.
This is closely related to the strong demand for
inland river transportation and implementation of the
standardization policy of inland ship type. During
the implementation of the policy of inland ship-type
standardization, from October 1, 2009 to December
31, 2017, 21.5 thousand small and old ships, with a
total capacity of 5874.4 thousand tons, were
disassembled. 22.5 thousand ships, with a total
capacity of 36941.2 thousand tons, were constructed
during 2009-2015. The total capacity of ships
constructed is 6.29 times that of the ships
disassembled. Therefore, the ship-type
standardization policy had certain promoting and
driving effects, but more new ships were constructed
due to the demand of capacity expansion and
updating driven by the market.

3 PROBLEMS IN THE
DEVELOPMENT OF INLAND
SHIPS
3.1 Poor Overall Quality of Inland
Ships Constructed
The report of the 19th National Congress of the
Communist Party of China declares that the
structural reform on the supply side should be
deepened, and the improvement of quality of the
supply system should be the main task in the
building of modern economic system (Jia, 2015).
Since 2003, a series of inland ship-type
standardization policies have been implemented. By
encouraging the dying out of small ships, which are
adverse to the efficiency of ship lock and violate
market demand, as well as the old, unsafe, energy-
consuming, and environmentally hazardous ships,
the economic, technological and green development
levels of the inland ships in China have been
comprehensively improved. In the end of 2019, the
average net load of inland ships in China was 1095
tons, 10.6 times that in 2000. The adjustment of
transport capacity structure has achieved remarkable
results, the efficiency of inland river transport has
been effectively improved, and the quality of inland
WRE 2021 - The International Conference on Water Resource and Environment
436
ships on the supply side has been greatly improved,
which has greatly promoted the development of the
shipbuilding industry. After the development of
inland ships in the past 20 years, a strong inland
transport fleet adapting to the rapid economic and
social growth has already formed. However, the
overall quality of inland ships is still far poorer than
that of European inland ships and coastal ships of
China, and the poor quality is the bottle neck of
shipping on the supply side.
Due to the long service life of European inland
ships, the requirements for materials, equipment, and
technologies during the construction are relatively
high, and more attention is paid to maintenance in
operation. 40-year-old ships still have good ship
conditions, capacities, and appearance, forming an
inland river landscape. In contrast, during the
construction of inland ships in China, the cost is
more important, and the requirements for materials
and technologies are less important. In addition,
maintenance is lacked during the operation.
Although the ships are young, their conditions,
capacities, and appearance are not as good as those
of the old ships in Europe, and are not in harmony
with the development levels of cities along the rivers
(CCNR, 2013).
The service life of coastal fleet of China is also
shorter than that of Europe, but the overall
conditions, capacities, and appearance of coastal
ships are qualified, showing no obvious difference
compared to Europe. The differences between the
coastal and inland fleets of China are closely related
to the attributes of their individual markets and
development of shipbuilding industry of China
(UNECE, 2011).
The construction specifications of coastal and
oceangoing ships are consistent, and the marketing
operation of coastal ships is closely correlated with
international ocean transportation. The circulation
between coastal and oceangoing ships is extensive,
and the construction of coastal ships is in line with
the world, so the overall construction quality level of
ships is synchronized with that in the world. On the
other hand, the shipbuilding industry of China is one
of the three largest shipbuilding bases in the world.
In 2019, the capacity output of global shipbuilding
in the world reached 98.82 million tons, while that
of China reached 36.72 million tons, accounting for
37.2%. The shipbuilding business is mainly export-
oriented, and is one of the most internationalized
industries in China. The market is highly
concentrated in China Shipbuilding Group Co., Ltd,
with the market share of as high as 90%. From
techniques and operation rules to various regulations
and on-site managements, all the construction
procedures are implemented in accordance with the
requirements of international norms.
In contrast, the construction of inland ships is
different. First, the inland ship construction
specifications and standards of China are formed
after learning from the relevant experience of the
former Soviet Union and European inland ships.
However, different from the oceangoing ships
circulating in a worldwide market, the inland ship
market is relatively independent, lack of room for
continuous improvement through global
competition.
Secondly, the distribution of inland ship yards is
scattered and disorderly, and most of them are
private enterprises. The shipbuilding and office
places are mostly rented river beach land and
wasteland. The facilities are simple and crude, the
production mode is extensive, and the techniques,
operation specifications, and on-site managements
are distinct. Additionally, the inland shipping
enterprises, which are mainly individual or small-
and medium-sized enterprises, are very sensitive to
the shipbuilding cost, leading to the big gap between
overall quality of inland ships and that of
oceangoing ships.
Thirdly, the inland ships are inexpensive and
low-valued compared to coastal ships, lack of long-
term attention. Under most circumstances, an inland
ship is exclusively designed and built by a private
small- and medium-sized shipyard. The ship design
and ship-type R & D abilities are far weaker than
those of the coastal ones, and both the ship design &
manufacturing and shipping enterprises lack
innovations and abilities.
Inland shipping enterprises are usually confused
when they build new ships. Generally, no shipyard
actively designs, develops, and promotes new ship
types, and only the existing ship types are selected
for construction and modification according to the
owner's experience, leading to slow promotion of
new ship types and new techniques.Innovations that
are the result of extensive dedicated research
projects are rarer and even hydrodynamic analysis or
hullform optimization through Computational Fluid
Dynamics (CFD) or model tests are often not
executed during the design stage of inland vessels.
In contrast, for seagoing ships, this is common
practice. The reasons behind this are not only the
gaps in the owner’s expertise and lack of financial
leeway, but also include the low building cost and
fuel consumption of inland vessels compared to
seagoing ships. This implies that the potential gain
from innovations is often not large enough to justify

large investments in research. Notable exceptions
include the crashworthy Y-shaped side structure
(Ludolphy, 2001), air lubrication of the hull to
reduce resistance (Foeth, 2008) and bio-inspired
propulsion (Berg, 1996; O-foil, 2015). These
innovations are all preceded by extensive research.
3.2 Great Environmental Protection
Pressure of The Existing Inland
Ships
The inland river transportation will have an
environmental impact on both banks, and this is
different from the main impact of marine
transportation, which is only caused by the entry and
exit of ships in the port and terminal operation.
However, the release of relevant environmental
protection standards of inland ships in China missed
the development stage of fleet scale fast expansion
and elimination and renewal of a large number of
old ships, directly affecting the overall
environmental protection level of inland ships.
Taking the emission of NOx as an example, the
inland-ship regulations phase I and phase II were
implemented in 2011 and 2015, respectively. About
50% of the existing inland ships were built before
the implementation of regulation phase I, and the
engine maintenance was insufficient in the actual
operation of inland ships, resulting in the
environmental protection pressures of ships such as
air pollution.
3.3 Difficult Renewal of the Inland
Shipping Enterprises
The recent survey of development of inland shipping
reports that most of the shipping enterprises tend to
upgrade the inland ships. The reasons are the
following. First, with the innovative technologies
such as new engine energy-saving technologies, the
economy of new ships will be greatly improved;
Secondly, the maintenance cost of most of the inland
ships will increase if their ages are longer than 10
years, and the economy is far lower than that of new
ships; Thirdly, the supply and demand of
transportation capacity in the inland shipping market
of China are more and more stable, and the focus of
business is changing from rapid expansion of
transportation capacity to occupy the market to the
improvement of operation efficiency of current
market.
The inland shipping enterprises surveyed reflect
that the disassembling of 10-year-old ships costs a
lot, and the ideal dealing mode is to sell it as a
second-hand ship. Some second-hand ships can be
sold to Southeast Asia. However, the inland river
freight volume of China is the largest in the world.
Especially, since 2000, the transportation capacity of
inland ships was expanded rapidly. The demand for
inland ships in Southeast Asia and other regions is
negligible.
4 SUGGESTIONS FOR
PROMOTING THE
DEVELOPMENT OF
HIGH-QUALITY INLAND
SHIPS
Currently, the shipbuilding industry is in the new
situation of market downturn and increasing
pressure of transformation, and the problem of
overcapacity is obvious. Most of the inland
shipyards are built near rivers. The environmental
protection pressure and safety risk along the Yangtze
River are relatively high, the adjustment,
transformation, and upgrading of industrial structure
are urgent. It is also urgent to integrate and optimize
the existing assets, by centralizing technologies,
intelligence, facilities, and other resources, and to
promote the integration and regrouping of inland
shipbuilding enterprises for the purpose of scale
benefit. The overall strategy to promote the high-
quality development of inland ships is to combine
the upgrading of inland ships with the structural
adjustment and transformation-upgrading of the
shipbuilding industry, to encourage the
disassembling and building activities of shipping
enterprises with financial subsidies, to reduce the
financing and insurance costs of shipping enterprises
by introducing financing and insurance institutions,
to reduce the increase of shipbuilding costs caused
by the improvement of quality, and to encourage the
daily maintenance activities of inland ships.
1. Promoting the high-quality development of
inland ship building industry on the supply side.
Promote the merging, regrouping, and cooperation
of large state-owned shipbuilding groups with
advanced technologies and strong shipbuilding
abilities with inland ship building enterprises with
strong comprehensive abilities, and improve the
design, construction technology, and equipment of
shipyards to improve the construction quality of
inland ships. The mode of "government-funded
support" should be adopted to guide the cooperation
between shipbuilding enterprises. The large-scale
ship enterprises provide technical assistance, and
WRE 2021 - The International Conference on Water Resource and Environment
438
small- and medium-sized shipbuilding and
supporting enterprises participate in the R & D,
production and manufacturing, R & D and
production of supporting modules and various parts,
to improve the overall technical level of inland ship
building industrial chain. Promote the
transformation of some shipbuilding enterprises into
ship maintenance and repair enterprises, develop the
entire-life-cycle service industry for inland ship
repair and maintenance, and improve the daily
maintenance level of inland ships.
2. Releasing and promoting preferable ship
types. The ship type optimized should be selected as
the parent ship for further modification and redesign
of the cabin layout and appearance. By optimizing
the materials and equipment operation and
improving the construction technologies,
characteristic inland ships which adapt to the level
of economic and social development in China can be
built, and the ship types should be released to the
society to encourage the development and
application of these types in primary inland river
shipyards. In addition, the technical schemes of
inland ships with advanced technologies such as new
energy, clean energy, and intelligence should be
released as demonstrations to lead the green and
intelligent development of inland ships.
3. Implementation of economic encouragement
policies to adjust the technical-level structure of
inland ships. Compensate the shipping enterprises
with a certain amount of subsidy for their
disassembling of inland ships with ages of 10
years, and provided subsidy for those enterprises
building ships with types encouraged after the
disassembling. On the other hand, introduce large-
scale financing and insurance institutions to provide
financing convenience for the shipping enterprises
that perform entire-life-cycle management and
maintenance of new inland ships, to reduce the
financing and insurance costs.
