rifl eet Leasing is expanding its tank container fl eet with
20 20ft 22,000 litre cryogenic tanks for gases, such as CO2,
liquid oxygen, nitrogen, liquid argon and LNG. The fi rst tanks
are already available, while the full range is scheduled to be
delivered by June.
The 20 additional tanks are built to the latest technical standards
for cryogenic tanks. They have an optimal payload due to the low
tare weight and high capacity of 22,000 litres. Compared with the
previous generation, the weight has been reduced by 500kg, from
8,000kg to 7,500kg) in the case of the 20ft 17.2 bar tank containers,
and by 1,250kg (from 9,550kg to 8,300kg) in the case of the 20ft 22
bar units.
Clients can thus benefi t from higher payloads, resulting in lower
transport costs and an improved environmental impact through
reduced transport needs. All CO2 cryogenic tank containers are
provided with a pump unit. Trifl eet expects to lease the new tank
containers mostly within Europe.
What makes the design of cryogenic tank containers particularly
challenging is the plethora of differing market demands and
respective design options. Cryogenic tank containers are vacuums
with multilayer super insulation and have expensive cryogenic valves
that need to be both fi re-safe and designed for extremely low
temperatures of -196degC. In addition, they need more approvals
and certifi cates than common tank containers. Altogether, this
Trifl eet’s 22 bar units have a tare weight 1,250kg
lower than previous generation cryogenic tanks
makes the engineering complicated and results in six-digit prices.
Given the complexity, a lessor needs considerably more than just
capital to offer cryogenic tank containers and related equipment. To
ensure it can bring just as much to the table as its partners, Trifl eet
acquired considerable expertise in the market requirements, the
design and the manufacture of cryogenic tanks and equipment.
“As an established tank container leasing company, we entered the
cryogenic business in early 2018,” said managing director Philip van
Rooijen. “The feedback we have received so far from the cryogenic
industry confi rms our technical abilities as a reliable partner offering

superior tanks and equipment. This early success and the market
growth expectations for cryogenic gases encouraged us to invest in
additional tanks, and we are ready to expand this specialised fl eet
further.”
Trifl eet leases tanks with a state-of-the-art design, leading to
holding times of, for example, more than 100 days in the case of
LNG. Furthermore, it offers ancillary equipment, such as cryogenic
pumps, hoses and installation systems. The company’s team,
managed by Jaap Kuijpers Wentink, possesses advanced technical
experience and in-depth knowledge of the market.
Prior to joining Trifl eet, Kuijpers Wentink was managing director at
the Crynorm Group, a manufacturer of LNG integrated systems, such
as tank systems, truck fuelling stations, liquefaction plants, bunkering
systems and vaporizers; all of which were cryogenic-related. Before
that he worked as managing director at tank lessor Cryotainer.
Trifl eet says it is now well positioned to serve the growing market
demand for cryogenic gases. Liquid gases such as LNG, liquid
oxygen, liquid nitrogen, liquid argon, and CO2 are all experiencing
signifi cant market growth.
The worldwide small-scale LNG market is projected to reach
US$51.9 billion by 2026, which shows a CAGR of 7 percent.
Growing demand for LNG as a low emission fuel, and therefore
addressing environmental concerns, is driving cryogenic equipment
demand.
The supply of LNG requires fl exible storage, which can be achieved
by operational leasing, says Trifl eet. What’s more, in view of the
signifi cant investment involved in LNG installations – of which
stationary tanks are responsible for the majority of this – the need
increases when it comes to turning capital expenditure into
operational expenditure by leasing storage through intermodal tank
containers.
But in addition to LNG, research outfi t Million Insights says the
global liquid nitrogen market is predicted to grow at a CAGR of 4.4
percent in the period 2018-2025. The worldwide CO2 market is
expected to grow at CAGR of nearly 7 percent up to 2022.
In March last year fi ve Trifl eet managers successfully completed the
basic training course ‘LNG as fuel’ at the STC Group, a worldwide
operating educational and research institution for the shipping,
logistics, transport, and process industries. This meant that the
Trifl eet team became certifi ed to work with LNG.
Martin Blom (area manager maintenance & repair), Patrick Broeders
(manager projects & innovations), Marco IJzerman (director fl eet
management), Edwin Wullems (manager maintenance & repair), and
Jaap Kuijpers Wentink himself went through an intensive two-days
training.
They covered the specifi c characteristics of LNG and the associated
procedures, when working with LNG and other highly fl ammable
fuels. For this they also dealt with practical situations, such as
bunkering and incident management.
This training was recognised by the Human Environment and
Transport Inspectorate (ILT) and is imported to learn and understand
what LNG is and what it means to work safely with this cryogenic
gas to minimise the risks for people, the environment, and the
equipment.
