Marine Knuckle Boom Crane (Sea Crane)

A Knuckle Boom Crane looks similar to a standard crane, however the boom articulates at the ‘knuckle’ near the middle, letting it fold back like a finger.  This provides a compact size for storage and manoeuvring.  They have become very common on offshore vessels as less of the deck space is blocked by the crane.

We offer certification on the Marine Knuckle Boom Crane from the following awarding body: NPORS.

NPORS Marine Knuckle Boom Crane (N014)

The aim of this course is to provide delegates with the knowledge and practical skills needed to safely operate a Marine Knuckle Boom Crane.  This course includes theory and practical elements, with tests being conducted on each.
