DNV And DSME’s Wind Propulsion Assistance System On The Way!

48

  • Daewoo Shipbuilding and DNV are collaborating to establish energy-saving wind assistance propulsion technology.
  • Both companies will jointly develop ship wind-assisted propulsion systems and will cooperate in future business.
  • A joint study is to be done on a Wind Assisted Propulsion System on deep-sea vessels such as LNG carriers and VLCC.
  • DSME’s Rotor Sail System got approved in March 2021 in principle from DNV.
  • The Rotor Rail System uses wind power to reduce ship fuel and greenhouse emissions.

DNV and DSME have signed an MoU to develop wind assisted propulsion system, says DNV.

DNV And DSME

Daewoo Shipbuilding & Marine Engineering (DSME) and DNV have signed a Memorandum of Understanding to establish energy-saving wind assistance propulsion. 

As a part of shipping’s global decarbonization efforts, DNV and DSME’s major emphasis will be on the wind-assisted propulsion system. Both companies will design the propulsion systems which will include fuel-saving device technology and a rotor rail solution.

The rotor rail system uses wind power to reduce ship fuel and greenhouse emissions. It is one of the next-generation eco-friendly technologies that deliver additional thrust to a ship’s propulsion power through aerodynamic coercion rendered by a rotating cylindrical column.

Key procedures

DSME’s Rotor Sail System got approved in March 2021 in principle from DNV. DSME has scheduled various tests to produce a prototype of the full-scale DSME Rotor Sail by the end of October 2022.

A joint study is to be done on a Wind Assisted Propulsion System on deep-sea vessels such as LNG carriers and VLCC. The primary tasks include DNV’s Type Approval Design Certificate (TADC) and technical support for the rotor rail system.

Ranging from classification, certification and advisory, DNV provides a range of services related to WAPS. DNV will soon release enhanced standards to ensure general safety improvements for ships with WAPS.

Views on the partnership

Dong Kyu Choi stated that the association between the two companies will speed up the realization and commercialization of innovative WAPS technologies.

Vidar Dolonen had said, “Achievements through our continuous cooperation led us to the signing of today’s MOU. DNV’s expertise in WAPS technology will greatly support DSME and the industry’s decarbonization efforts.”
