MARINE applications

INNOVATION RULES THE WAVES

LNG is the clean and economic marine fuel for the future.

The new regulations for the sulfur emissions in the Baltic Sea and in the North Sea, and their extension to the Mediterranean Sea, the US coasts and probably along some Asian countries coasts are strongly pushing LNG-related investments and innovation in the marine industry.

All the key role players of this industry have started to invest in technology, infrastructures, new dual fuel or gas only engines for ships and vessels, and in new LNG bunkering vessels also.

  • Spray pumps or stripping pumps on LNG carriers and LNG bunkering vessels
  • Main or back-up pumps for feeding gas to low pressure marine engines, with differential pressure that can reach up to 20 bar
  • Small to medium cargo pumps
  • Ship to ship bunkering pumps
  • FSRU / booster pumps, with differential pressure that can reach up to 55 bar
 

According to customers’ requirements, such pumps can be mounted:

  • At the bottom of the LNG tanks
  • Or inside vacuum insulated cryogenic sumps, installed at the foot of the LNG tank
 

In both cases, the seal-less concept, with motor bearings permanently lubricated by LNG, allows a permanent cold condition for:

  • Quick and efficient start and stop operations
  • 'Extremely low maintenance need
 

Marine high-pressure applications

Vanzetti Engineering has recently invested in the research and development of the VT-3: a new reciprocating pump designed and built according to the marine class rules.

VT-3 pump can be applied as high-pressure pump for feeding gas to the MAN MEGI engines:

  • In configurazione TRIPLEX
  • Flow rate up to 143/h
  • Pressure up to 350 bar
 

VT-3 can be supplied on skid, class approved also, with all the accessories such as sensors, instruments and valves for a safe and reliable pump control.

Bunkering Vessels

ARTIKA submerged pumps models can bunker LNG at different flow rates and head.

For example, the ARTIKA 300-2S model can reach up to 250 m3/h of flow rate at max. 12 bar as differential pressure, thus ensuring a quick and reliable operation. All Vanzetti Engineering pumps can be class certified according to the ship class society required for the project. 

Safety and high reliability are our core design concept.

LNG carriers

With numerous marine pumps projects supplied and several in its order portfolio, Vanzetti ARTIKA submerged pumps are the optimal answer when customers are looking for:

  • Fuel Gas pumps
  • Spray Pumps
  • Stripping Pumps
  • Cargo Pumps

on Small, Medium and Large LNG Carriers.

Depending on the requirements, the ARTIKA models can pump the LNG from extremely low to very high flow rates, with supplied differential pressures that can vary from minimum levels up to the almost 20 bar necessary for the XDF two strokes engines.

Our engineers competence allows to quickly study the customers’ requirements and to promptly supply all the technical documentation related to our LNG pumps proposal, including the pump's theoretical performance curves. 
If a Fuel Gas Pump for an LNG Carrier equipped with MAN MEGI two stroke engines is needed,our VT-3 models are the right solution in terms of performance, safety, reliability and low needs of maintenance. 

Depending on the engine consumption requirements the VT-3 can be tailored by our engineers in SimplexDuplex or Triplex configuration and it can be supplied on skid version with all the accessories, instruments and sensors for a reliable and safe operation.

LNG fuelled ships

Depending on the engine type and characteristics, the Fuel Gas Systems pumps can be either submerged type ARTIKA models or piston type VT-3 models.

FLOATING STORAGE REGASIFICATION UNITS (fsru)

Orders for such vessels are constantly increasing, since it’s the best solution for a cost-effective, movable gas supply to:

  • Power plants
  • Industrial areas
  • Small towns on coastal areas
  • Islands with no gas grid

 

Depending on the customer needs, Vanzetti Engineering can supply different pumping solutions for FSRU projects:

  • The bestseller ARTIKA 200-4S, which can give more than 30 m3/h flow at 35 bar
  • The new developed ARTIKA 200-6S, able to reach up to 55 bar differential pressure.

 

Such pumps can be either installed in-tank or in-sump. Their extremely high reliability guarantees continuous process conditions for all customers applications.

SHIP TO SHIP BUNKERING

ARTIKA submerged pumps models can bunker LNG at different flow rates and head. All our pumps can be class certified according to the ship class society required for the project. Safe and reliable operation are the basis of their design concept.

According to customers’ requirements, ARTIKA pumps can be mounted:

  • At the bottom of the LNG tanks
  • Or inside vacuum insulated cryogenic sumps, installed at the foot of the LNG tanks

In both cases, the seal-less concept, with motor bearings permanently lubricated by LNG, allows a permanent cold condition for:

  • Quick and efficient start and stop operations
  • Extremely low maintenance need
