Gas generators for auxiliary work on ships in ports – Air quality improvement campaign


  • Reduction of NOx, SOx and particle emissions to the atmosphere.
  • Reduction of CO2.
  • 30% exhaust noise reduction compared with the equivalent Diesel electric genset and 50% reduction in the engine noise.
  • Modular power installation starting from 250 kWe without any maximum power limit.

The Opportunity

Reducing the emission of pollutants from boats facing increasingly stringent environmental regulations, ship operators are being called upon to minimize marine emissions during loading and unloading operations in ports.

The Solution

Accordingly, Guascor Energy has developed a comprehensive solution to reduce emissions in ports. As such, Guascor Energy is providing a solution based on a gas engine incorporating Guascor Energy G-56SL, 808 kWe (50 Hz) engine, installed in a 40-foot soundproof container. The technology is certified by Bureau Veritas with the Individual Certification for AUT-MS (unattended engine room). The system allows auxiliary electrical energy to be supplied to the boats docked at port.

Framed in the CORE LNGas hive program, this innovation project co-financed by the European Union, is led by the Port of Barcelona and coordinated by Enagás. Als participating as strategic partners is the shipping company Fleet Lines Suardíaz, which has adapted the ship L’Audace with which the pilot test is being carried out; Guascor Energy, which has built the gas generator in the factory of Zumaia (Spain); the Ham company, which has provided the liquefied natural gas (LNG) deposits; Bureau Veritas, which has certified our engine for marine use; and the ports of Tenerife and Vigo and Barcelona, where the test were carried out.

Among the multiple advantages that it offers, the gas-engine-based solution does not generate soot particles or Sulphur oxides (SOx), while producing 80% fewer NOx emissions and less greenhouse gases compared to a conventional diesel solution. The system therefore significantly contributes to reducing polluting emissions, a feature which is in high demand. The ports in Barcelona, Vigo and Tenerife in Spain, for instance, have all signed up for this Air Quality Improvement Campaign, using this innovative auxiliary electrical generation system.

Upon arrival to port, the boats are connected to the electrical power station and the LNG electrical genset is in charge of supplying the electrical power that the ship needs for its port operations. The external electrical genset acts as another auxiliary set for the ship, giving the crew the possibility to turn off the electrical genset(s) on board which use heavy fuel or diesel.

The electrical genset installed in the container is cooled directly with sea water through a system of pumps and heat exchangers, thus contributing to reducing noise emissions by not using cooling fans.

For a greater power capacity to be supplied, our Guascor Energy machines can be connected in parallel by setting up a generation plant based on multiple engines. In this way we can achieve modular power which could range from 250 kWe up to covering the maximum power required based on the needs of each port depending on their traffic and activity.
