Nora B

DP2 Hybrid MPP OSV – 35 x 15 m

Our NORA B is a unique DP2 hybrid multipurpose offshore support vessel (MPP OSV) designed for subsea operations in medium to shallow waters.
Combining versatility, efficiency, and advanced technology, she delivers outstanding offshore performance across a wide range of projects. Managed by ZOFF and crewed by highly qualified professionals onboard and ashore, NORA B ensures smooth integration with client systems and personnel throughout every project phase — mobilisation, execution, and demobilisation.

Onboard systems provide power supply, hydraulic services, communications, and safe launch/recovery arrangements for both subsea and deck equipment. This makes her ideal for complex offshore campaigns, including:

 

  • PLGR & trenching & cable burial Operations
  • ROV operations
  • Mattress installation
  • Subsea cable landing & laying
  • Offshore survey operations
