Project Mandate and Specs

Design the electric power system for a ship of about 50 meters long, 7 meters wide, 4 meters deep, 3 meters draft design, and it has a cargo capacity of 1000 tons. The powertrain should be equipped with electric propellers and a mix of supercapacitors and battery pack. The powertrain reportedly should enable a range of at least 100 km on a single charge.

1. High capacity batteries to design

2. Marine Wind Turbines

3. Investigation of the power electronics on board

4. Battery pack recharging

5. Electric propellers

High Capacity Batteries

The high quality and long life batteries from Furukawa Battery can be supplied either as part of an integrated marine or ship renewable energy solution or supplied as stand-alone battery packs (with cables) or individual units.

UB-50-12 valve regulated lead acid (VRLA) batteries or battery packs are the ideal solution for smart grid, wind power and solar power applications and can be used on ships. UB-50-12 batteries can be supplied as individual units or as a pack for use with EMP solar power solution. Marine grade battery frame kits are available in 2.4kWh 3.6kWh sets or customised frames can be supplied as requested. In conjunction with a wind powered generator, both the the battery and the generator can work on conjunction to power the boat. Please see Block diagram for details.

Marine Wind Turbines


Rutland 504 Marine Wind Turbine 80W simply convert the free and abundant power in the wind to power stored in your batteries. The 12V power is ready to use for engine starting, lights, coolers, essential navigation equipment and other low energy appliances.

Recharge Proposal

The use of solar panels over the highest surfaces of the boat to avoid shade as best as possible. The solar panels are to be connected in parallel to make sure the lead-acid battery pack is still charging regardless of lack of sunlight on other panels.
