Project-specific shaft lines for wood, fibreglass and steel vessels

SHAFT LINE

A complete shaft system matched to the vessel

Different shaft systems are engineered for wood, fibreglass and steel vessels. 304, 316 and 316L stainless shafts are used in production, with certified or non-certified systems prepared to suit the project and class requirement.

ERC BOW THRUSTERS

More precise port–starboard control in harbour

Diesel, hydraulic or electric drive options are combined with a seawater-resistant shaft and seal arrangement plus a high-strength gear system for demanding duty.

  • Quiet gear transmission
  • Wear and corrosion resistance
  • Three drive choices to suit the project
