Sauter Carbon Offset Design (SCOD) presented earlier this month, their latest project,
Emax Deliverance - a DynaWing  Solar Hybrid Supertanker.

The 330,000 dwt tanker with the dimensions LOA 1395 ft (426 m), beam 176 ft (54 m) and draft
59 ft (18 m) is designed to pass through the larger locks of the post 2014 Panama Canal.
Compared to conventional tankers of similar capacity, the new design is longer,  narrower and
has less draft and uses a Mitsubishi Air Lubrication System (MALS), thereby reducing resistance and
therefore delivering higher efficiency.

Propulsion is by a twin arrangement of a pusher propeller with a counter rotating puller propeller
on steerable pod, powered by Wärtsilä dual fuel LNG engines with additional power coming
from a Solbian solar power generating array. Energy can be stored in a Litihum ion battery pack
for propulsion or later use  to provide power for hotel load purposes. In addition the tanker is
equipped with twenty masts supporting DynaWing sails with computer controlled, automatic
furling, inside the boom, giving a variable sail area up to 5.38 million square feet (500,000 m2).

According to the designers, a tanker of this size would normally have a 30MW diesel engine
installation, however with this higher efficiency hull only 20 MW would be sufficient of which
10 MW would be provided by the LNG engine and an equivalent 10 MW using sun and wind
energy, 4 to 8 MW from the Dynawing and 4 MW form the solar array.

The nett benefit is claimed to be a reduction in GHG emissions of between 70 to 85 per cent,
made up of 35 per cent from the pod propulsion system and low hull resistance, 20 to 30 per cent
from the DynaWing, and 15 to 20 percent from the solar cell generation. On an annual basis this
will deliver a saving of 110,000 tons of CO2, equating to a total reduction of CO2 of 3 million
tons over the 25 year life of the vessel.

A no BRAINER now more than ever.

The seed has been sown, the ideas will flourish, and eventually, we might just see fleets of "unconventionally" powered cargo ships.

30 years ago, who would have though it even possible?

Maravilloso, espero sea realidad pronto .Buena navegación y viento a un largo
