Parametric Rolling Movement prevention system from HHI gets LR approval

Lloyd’s Register has awarded Approval in Principle (AiP) to Hyundai Heavy Industries (HHI) for its new Onboard Guidance System, designed to prevent excessive container roll, or Parametric Rolling Movement (PRM), on container ships.

The technology, developed through a Joint Development Project with HHI, Eastern Pacific Shipping and Lloyd’s Register, evaluates the stability of the roll motion of the container ship during operation.

The software considers various loading conditions and sea conditions and provides guidance on board based on actual operational information, working in conjunction with Hyundai Global Service’s Integrated Smartship Solution (ISS).

During the approval process, the Onboard Guidance System was tested as part of a pilot on a 15,100 TEU Eastern Pacific Shipping container ship.

“With the development of the technology, our client is able to reduce unnecessary cost due to the loss of containers and HHI has come to secure differentiated competitiveness as a shipbuilder that ensures safe operation at sea,” said Seungho Jeon, Chief Technology Officer, Hyundai Heavy Industries.

“It also has a significant meaning in that we have established a foundation for further advancing the system by completing a pilot test on the EPS vessels in operation.”

The approval follows a number of recent projects between LR and Hyundai, including an SCA (Software Conformity Assessment) for HHI’s Digital Hi-PIX Digital Twin core technology to predict the structural integrity of an IMO Type B fuel tank, along with the announcement of a Joint Development Project (JDP) to promote a new ‘Future Shipyard Model’.
