CLAMP-ON PMSG

Functionality

PTO: in PTO mode, the ship’s conventional gensets are stopped. The electrical power is supplied by the main engine through the waste heat recovery (WHR) system and the SeaGreen PTO shaft generator. The main engine fuel is much cheaper than the Diesel Oil.

PTI: In PTI mode, the ship’s fitted gensets are operated if required. An additional mechanical propulsion power is supplied by the SeaGreen PTI shaft motor through the variable frequency drive (VFD), enabling a speed boost

Benefits

  • Reduced emissions
  • Reduced complexity and footprint of the system
  • Higher reliability
  • Reduced CAPEX and OPEX
  • Increased flexibility

VFD

.We were recently on-site at Guangzhou Wenchong Dockyard (GWD), overseeing the installation of another Variable Frequency Drive (VFD) on board our client’s Newcastlemax bulker. This marks yet another step in a series of VFD installations across their fleet—an important move towards greater energy efficiency and operational flexibility.

At the same time, we had the opportunity to check in on the ongoing installation of a 3MW shaft generator for another shipowner. With demand for shaft generator retrofits on the rise, it’s great to see shipowners actively embracing energy-saving solutions that align with evolving regulations and decarbonization goals.
