Customer: Admiral Shipyard, Italian Sea Group 

Challenge:

VULKAN was involved in the construction of the aluminium megayacht Quinta Essentia and was commissioned with the design of a propulsion unit for an advanced hybrid propulsion system.

Solution:

The Quinta Essentia has been equipped with an advanced hybrid propulsion system that integrates two MAN diesel engines of 1,400 horsepower each with two 150 kW electric motors connected to variable-speed power generators.

The propulsion line includes an integrated system interposed between the diesel engine and gearbox that allows the electric motor to be engaged and disengaged via a centrifugal coupling.

Power management is realized with an Emerson system that combines hotel service with propulsion. The propulsion unit, which VULKAN has designed, includes T mounts elastic suspension system one layer of (anti-vibration mounts positioned under the machineries and a second layer under the common base-frame), with PROPFLEX T installed on the shaft line to guarantee the highest standards of comfort on board.

Advantages:

The result of the project is a complex system capable of combining the pleasure of sailing electrically in complete silence with a rather sophisticated propulsion system, with great attention to detail, to ensure that the traditional components, diesel engine and mechanical couplings, does not nullify the design effort. This results in a boat capable of guaranteeing comfort in all conditions of use.

Technical Data of the Quinta Essentia:

Length: 55.0 meters

Beam: 10.20 meters

Draft: 2.45 meters

Tonnage: 851 GT

Speed: 12 knots
