in the world, EiC Cryo is the only
manufacturer of its kind with
the knowledge and expertise to
provide the most complete catalog
of both standard and custom
cryogenic pump equipment in
the world. EiC Cryo incorporates
the highest caliber of quality,
engineering and technological
advancement,
delivering
the
most dependable and efficient
equipment you can buy.
marINe
aPPLICatIONs
EIC Cryo offers complete package solutions
for all of your marine pump requirements.
These units are available for all shipboard
and floating applications and are used for
main cargo unloading, stripping/spray,
fuel and emergency (retractable), high
pressure and expander services.
Depending on your unique requirements,
flow capacities range from 5 to 3000m3/h
with heads available over 200 meters.
additionally, electric power feed cables and
deck penetration assemblies are custom
manufactured at EIC Cryo’s Sparks, NV
facility and meet all requirements of
major ship classification societies. Special
designs with built-in internal filtration are
available to handle cargo that is likely to
suffer particulate contamination such as
LPG.

• An Entire ship’s cargo can be unloaded in
approximately ~12 hours.
• Single and multi-stage designs available
• Spray pump designs have such an extremely
low nPSH, cargo tanks can be offloaded to
near-zero liquid levels:
• Increasing the amount of delivered cargo
• Reducing the cost of transportation and heel
product in the tanks during the return
voyages
• Spray Pumps commonly achieve a nPSHr as
low as .3 meters and are often used for
recirculation, reducing boil-off gases.
emerGeNCY
in the highly unlikely event that both cargo pumps were to fail onboard, an
emergency pump can be used to empty the cargo pump storage tank. Thousands
of our cargo pumps have been delivered and there is no history of any of our
emergency pumps ever having to be used due to pump failure, a testament to
the reliability of the EIC Cryo design.
FueL
EiC Cryo has developed low flow, high head lng fuel pumps. These submerged
pumps are designed to meet the rigorous conditions of marine fueling applications.
The rugged construction of these pumps allows years of uninterrupted service,
even while operating with fuels containing some amount of contamination.
muLtI-LIQuID & DuaL-DutY
The multi-Fluid Cargo Pump allows the ship to offload not only lng but lPg
or lEg without modification to the pump. The pump is designed specifically to
operate at various temperatures and densities, therefore allowing one pump
for multiple applications. Dual-duty cargo pumps allow a single machine to
accommodate both feed and offloading pump applications.

Submerged motor pumps and expanders are well suited to the growing business
of floating installations. The compact design of a submerged motor pump
results in a machine approximately half the size and one-third of the weight of
an equivalent external motor pump; an important advantage where space and
weight are at a premium.
Suction Vessel mounted pump models are used in high-pressure send-out service
on FSrus and in several process services on FPSos. retractable pumps service
the storage tanks on the vessels. Expanders can be found on the Flng topside
modules.
Various Types of Pumps for Floating applications:
• High Pressure Booster Pumps
• regas Feed Pumps
• Cargo Pumps (below deck)
• Process Pumps
• Expanders
• For many years, the traditional method to let down pressure in a liquid
stream used a Joule-Thomson (J-T ) valve. an improvement in the overall
efficiency of this let-down process can be achieved by replacing the J-T valve
with an expander. in doing so, the overall plant efficiency will increase,
reducing operating costs and increasing LNG production.

• Expanders increase production of liquefied gas by
~20 tonnes per day.
• Each megawatt of generated power increases the
lng production by ~60,000 tonnes per year.
• Expanders remove otherwise wasted energy
from the lng stream, decreasing the total power
consumption and further cooling the cryogenic fluid.

Floating service pumps are subjected to additional loads due
to ship hull motion. These loads are present during sea towing
and during operation while moored at site. Vessel mounted
pumps and expanders incorporate additional lateral supports
to reduce the stress on the vessel mounting lugs. Within
the vessel, the pump is protected from lateral loads by the
use of a lower support rod. retractable pumps use a deepseat style suction valve or a rigid
retraction system to eliminate the
possibility of the pump unseating
from the valve seal surface during
hull motion. In cases of extreme
loads, a shaft locking device can
be applied, preventing movement
of the shaft during shut-down. it
can be externally controlled and
wired into the plant safe-guarding
system with appropriate interlocks.

The liquefaction, marine, land, transport
and regasification industries are changing.
Facility size, storage, distribution and
transportation methodologies are all
progressing, delivering power and energy
to even the most unlikely, difficult-to-reach
corners of the earth. regardless of where
you are in the global LNG pipeline, EIC
Cryo has the pump or expander to support
your specific application.
