MARINE

Innovation rules the waves

LNG is the clean and economical 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 ships.



All the Vanzetti Engineering centrifugal submerged pump models can be class approved and, according to their size (proportional to flow rate) and number of stages (proportional to head) can find applications as:

  • 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:

  • On 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 need of service and maintenance



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 is already available and can be applied as high-pressure pump for feeding gas to the MAN MEGI engines:

  • In TRIPLEX configuration
  • Flow rate up to 14 m3/h
  • Pressure up to 350 bar


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

Bunkering Vessels

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

For example, the ARTIKA 300-2S model is able to reach up to 250 m3/h flow at up to 12 bar 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 at the core of their design concept.

LNG carriers

With more than twenty marine pumps projects completed and supplied, and tens 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 customers’ requirements and promptly supply all the technical documents related to our LNG pumps proposal, including the performance curves.
If you need a Fuel Gas Pump for an LNG Carrier equipped with MAN MEGI two stroke engines, 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 Simplex, Duplex or Triplex configuration, and can be proposed on skid version with all the accessories, instruments and sensors for reliable and safe operation.

LNG fuelled ships

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

These two families can be applied to all kind of LNG fuelled ships. Vanzetti is the sole supplier of all the Fuel Gas Systems pumps of the Carnival Corporation LNG Cruise Ships that will start to operate from the end of 2018.

Vanzetti also supplies Fuel Gas System pumps to the Royal Doeksen LNG catamaran ferries, where the flow rate demand is very low. The ARTIKA 120-3S model guarantees reliable and stable both flow and pressure output, even at these very low flow rates.

Container vessels such as the Wes Amelie (converted vessel) or the Nordic Hamburg / Containerships Container Vessels (new built) exemplify some of the many small flow rates ARTIKA pumps applications: in one case for 4 stroke engines, in the second one for 2 stroke XDF engines. The ARTIKA 120 model is modular from 3 to 6 stages, allowing to cover the full range of marine gas engines.

The first trans-Atlantic Post Panamax LNG Car Carriers to be built owned and operated by Siem Car Carriers. It will be equipped with MAN MEGI two stroke engines and our VT-3 Fuel Gas Systems pumps. Depending on the engine consumption requirements, the VT-3 pump can be tailored by our engineers in Simplex, Duplex or Triplex configuration, and can be proposed on skid version with all the accessories, instruments and sensors for its reliable and safe operation.

Other interesting applications are the Heerema Semi-Submersible Crane Vessel (SSCV) Sleipnir, where 16 of our ARTIKA 160 pumps are installed, and the LNG Crude Oil tankers built in Samsung Heavy Industries.
In both cases our 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 customers’ requirements and promptly supply all the technical documents related to our LNG pumps proposal, including the performance curves.

Floating Storage Regasification Units (SFRU)

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 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 Vanzetti 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:

  • On the bottom of the LNG tanks (type A, B or C)
  • 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, and extremely low need for service and maintenance.
