ELOMATIC GIVES MORE DETAILS OF NYK ZERO-EMISSION SHIP CONCEPT FOR 2050

Thursday, November 29, 2018 

Consulting group Elomatic has revealed further information about the NYK Super Eco Ship 2050 emission-free pure car and truck carrier (PCTC) concept, which it developed with NYK of Japan and NYK’s technology arm MTI.

Compared to current vessels, the NYK Super Eco Ship 2050 is expected to reduce CO2 emissions by 100%, and reduce energy derived from bunker fuels by about 70%.

The concept design was unveiled by NYK Group in mid-November, see https://www.mem-online.com/news/article/nyk-group-unveils-the-future-pctc.html . Elomatic was responsible for the concept creation and visualisation. The NYK Super Eco Ship 2050 is a follow-up from a project undertaken in 2009 by the same parties, which culminated in the design of a container vessel for 2030, the NYK Super Eco Ship 2030.

The resistance of the NYK Super Eco Ship 2050 was reduced by 35% by remodelling the hull to decrease water friction, by reducing the weight of the hull, and by minimising air resistance. The improvements were validated with CFD calculations. Further improvements were made by introducing fuel cells for electric propulsion, use of waste heat recovery, and the generation of renewable energy on board the vessel. Energy demand has been cut by 67% by eliminating energy and operational waste. Instead of fossil fuels, the ship is powered by hydrogen produced from renewable energy sources.

The ship features lightweight structural materials, while stability is ensured by the use of active pontoons on each side and gyro stabilisers rather than using ballast. Air lubrication is employed to reduce hull resistance, and hull smoothness is further aided by the use of automatic cleaning robots used during port stays. Some 9000m2 of solar panels provide for 15% of energy demand.

Other elements in the concept include the use of 3D printing for building materials, the 'digital twin' concept to aid maintenance, while screw propellers are replaced by flapping foils inspired by the swimming actrion of dolphins. Route optimisation and planning will be carried out on shore, at port and fleet level, enaling a just-in-time  supply chain. Shorter port stays will allow for slower sea navigation, and will be aided by simultaneous ship-to-berth and ship-to-ship cargo transfer. Automatic mooring and berthing will further reduce hours in port.

“We are honoured that NYK Group have continued trusting in our ability to provide technical and technological solutions for a greener future. One of our core goals is assist our customers in their struggle against the most significant challenges of our time. The greatest of these are environmental wellbeing, resource sufficiency and questions related to technology upheaval,” said Elomatic CEO Patrik Rautaheimo.
