Hyundai Heavy mega crane uses MacGregor VFD winches

MacGregor 90 tonne electric main hoisting winch

APRIL 30, 2015 — Cargotec’s MacGregor subsidiary has delivered and commissioned 45 variable frequency drive (VFD) winches and a full control system for the recently completed heavy-lift crane barge Hyundai HLV-10000, one of the largest heavy lift vessels in the world.

Shipbuilder Hyundai Heavy Industries will use the crane, built at the Yeongam, South Korea, shipyard of its Hyundai Samho Heavy Industries subsidiary, to install bigger modularized blocks that have been built on shore onto offshore facilities (see earlier story).

MacGregor’s electric winches consume 25 to 30 percent less energy than equivalent hydraulic winches. In lowering mode, they generate energy rather than consume it. Electric winches benefit from reduced installation and maintenance costs, reduced environmental impact and simplified diagnostics.

“This delivery extends MacGregor’s heavy lift vessel portfolio,” says Francis Wong, Head of Sales and Marketing at Offshore Deck Machinery at MacGregor. “It also confirms our ability to meet the developing needs of specialist vessels, supported by our good track record for all types and sizes of winches and cranes from merchant ships to offshore support vessels.

“We won this contract because we offer the most advanced winch and crane technology, underpinned by our worldwide service support organization.”
