Future ship design - Expectations

Reduced environmental footprint

Increased safety

Increased cost efficiency

Increased safety

Autonomous ships

Today we have a Integrated Bridge Systems with • ARPA

• ECDIS

• Auto-tracking

• Auto-pilot

• AIS

• D-GPS

• Predictor

Autonomy requires integration of additional equipment and sensors for a reliable situation awareness system

New stability rules are under development

New requirements regarding fire safety are discussed

Increased cost efficiency (CAPEX and OPEX)

• Optimal and simple steel structure hull design for the intended service.

• Reduce the number of systems installed onboard

• Equipment used in port shall not be installed onboard

• Expensive equipment to be installed as late as possible

• Reduce the amount of cabelling utilizing modern technology

• Reduce piping by optimal arrangements

• Evaluation of present timetables including turn around in port for optimum operation with regards to customer demand and service speed

Reduced environmental footprint

IMOIIMAX features:

• A hull design that is developed for an operational range of speeds and drafts instead of a specific speed at a design draft

This has resulted in

• A hull with an unconventional bulbous bow and shape of skeg and stern

• A propeller with a larger diameter and a lower rpm including a propeller boss cap fin

• A derated main engine

=> 30% less installed power

Reduced environmental footprint

Reduced environment footprint - Energy Efficiency Focus

• Maintaining the tradition to find optimal hull form for all new building projects

• Implement fuel saving arrangements on existing fleet

>300 projects have been implemented

>30 vessels have equipment for RTM (Real Time Monitoring) and FMS (Fuel Management System)

• Best practise is coordinated between Stena’s business units for fuel efficiency

• Development of technology is continously followed up

Fuels for the Future

Our view is that we have to face a fuel mosaic as different ship types need different solutions.

• In a 10-15 year perspective HFO with scrubber, LSHFO and MGO will still be the most used fuels for ships due to their cost effectiveness (including a proposed CO2/tonnes fee of abt 50USD/tonnes CO2))

• LNG will be a suitable fuel for new built ships in certain areas as logistics need to be well developed

• Methanol/Ethanol can be looked upon as a step towards fossil free shipping.

• Battery powered ships will be an attractive alternative for short sea shipping 15 years from now. Distances less than 100nm.

• In a longer perspective bio fuels and fuel cells will enter the market

Fuels for the future – Battery price expectation

Pilot projects onboard the Stena Jutlandica planned to start in 2017

• Step 1: Battery power on the thrusters

• Step 2: Conversion on two of the main engines

• Step 3: New customized ship, Stena Elektra, plug-in hybrid that is charged with green shore power and during operation

100% battery power in port and archipelago - no emissions in the coastal environment

In the open sea the ship is operated with MGO or methanol.

Steps towards the worlds largest plug-in hybrid vessel

Step 1 - Battery powered bow thrusters

Step 2 – Conversion on two of the main engines

Step 3 – New customized ship, Stena Elektra

Stena Elektra – A concept study of a future hybrid RoPax

The RoPax of the future!

• Battery technology

• Alternative fuels (for distances >100nm)

• Fuel cells in the future

• Autonomy for increased safety

• Modularized and flexible arrangement

• Reduced air resistance

• Further developed hull form and propulsion arrangement

Stena Elektra – A reality 2030!
