Color Hybrid – Sandefjord-Stromstad itinerary

Distance: 38 nm

Transit time: 2h30min

Turnaround time: 30-70 min

Color Hybrid – Power plant configuration

Main engines: Father/Son 2x6L / 2x8L: 3,600 kW/ 4,800 kW

Main generators: 2 x 4,450 kW

PTI/PTO: 2 x 2,700 kW

Battery package: 2 x 2,350 kWh

In addition (Not shown):

A heat reservoir (utilizing

heeling tanks) storing

5MWh (ΔT = 15C)

of waste heat from

combustion engines for

use for heating while

sailing on batteries,

during port calls and

night stop.

Vessel can utilize 4

sources of energy;

• Diesel (MGO)

• Shore Power

• Batteries

• Heat Reservoir

Electric heater if heat

reservoir is empty

4 x Exhaust water heaters for heat reservoir

Color Hybrid – Main CharacteristicsFlag & Regulations;

Flag: Norwegian / NOR

The vessel is designed for Short International Voyage including SOLAS probabilistic damage stability

(and Stockholm Agreement; Hs = 4,0 m) as pr. rules, Safe Return to Port (72 nm) and latest

MARPOL amendments. Ice class: ICE-1B.

Furthermore volantary ceretificate

with SOLAS 2020 (damage stability) and

MARPOL Tier III (NOx).

Dimensions and some capacities (approximate);

Length overall: 160 m

Breadth: 27,1 m

Draught: 6,0 m

Design speed: 17 knots

Max Speed: 20+ knots

No. of persons on board: 2100 (2000 pax +100 crew)

LSA for 2100 persons

Color Hybrid – Operational modes

• A number of main operational modes are developed:

– Harbour mode with battery charging in Sandefjord

– Maneuver mode on battery in Sandefjord

– Slow speed mode on battery in Sandefjord fjord.

– Several transit modes (pending speed requirement etc)

– Slow speed mode DE/DM in Strømstad

– Maneuver mode in Strømstad

– Harbour mode in Strømstad

>

Color Hybrid – Battery package

• Appx 20% of the energy consumption done with green electric power, (CO2 neutral)

• Shore power in Strømstad will increase above number

• 12knots for up to 60 minutes incl hotel load of 750 kW per roundtrip/charging.

• Capacity 4,700 kWh of batteries

• Output voltage 700 – 1000V DC

• Weight of total battery package is abt 65 tones

>

Color Hybrid – Environmental benefits

• The environmental and other benefits with use of batteries are quitesignificant:

– Transfer energy consumption from ‘dirty’ to ‘clean’ energy, reduce fossile fuelconsumption

– Emissions of CO2, NOx, SOx and particles are reduced

– By use of batteries for peakshaving, diesel engines can operate at optimal load

– Use of batteries as ‘spinning’ reserve (e.g. no need to start another D/E during maneuver or slowspeed in narrow waters)

– Eliminate or significantly reduce emissions in sensitive areas

– Batteries can be loaded immediately when connected and have extremely gooddynamic response to load variations

Color Hybrid – Battery usage for peak shaving

Peak shaving

“Peak shaving”

(and “Spinning

reserve”)

conditions give

better

operational

conditions for

diesel engines.

Added bonus

with battery

hybrid

systems.

The availability of local a high-capacity electric power grid for boost charging (6,5 MW) at a

daytime turnaround in Sandefjord and the vessel’s operation plan (2 returns trips per day and

an overnight stay in Sandefjord).
