Sustainable Ship Design Concepts

Tutorial 1 – Selection of ship concept idea & Group formation

Some key figures on shipping

Responsible for 90% of the world trade

Annual growth rate of 3% annually

In 2015 shipping carried over 10 billion tons

of goods around the globe

Some concerns…

The start of Resilient Policy“The IMO Strategy aims to

reduce emissions

according to the Paris

Agreement temperature

goals. Therefore, the

shipping industry have to

improve their operational &

technical efficiency, without

compromising safety”.

Commuter Ferry 2.0 – From Wasa to Umeå

13.9.2019

Design of a zero emission Ferry to route between Wasa and Umeå for year around

operations. The ship should enable ease of transportation in Northern part of Baltic

bridging Finland and Sweden and offer an inspiring work environment. Challenges :

• Design of multi-purpose public spaces that support work and leisure

• Clean, zero-emission operations with water with waves and ice cover

• Development of related business models.

The project would require strong input from the Passenger Ships – course.

Ship du SoleilDesign of a ship (either a newbuilding or a conversion) with (multi-purpose) spaces facilitating customers’ on-board experiences (e.g. an inspiring work environment, spaces supporting the learning of new skills, etc.)

• The motivation for the concept stems from a trend towards “self-improvement holidays”, combining work / self-development with pleasure

• Design challenges- Design of multi-purpose public spaces (spaces that can be

adapted to facilitate various types of experiences) and a general arrangement that support those

- Development of related business models

Periodically-autonomous ship with reduced manning

Design of a ship with a reduced manning demand enabled by a high degree of on-board autonomy• The motivation for the concept stems from the

assumption that gains in cost-efficiency could be achieved by reducing a ship’s manning requirement using autonomous technologies

• The mission of the ship would be to transport dry cargo (steel products) between Finland and Sweden (with local regulatory approval)

• Design challenges include:- Rough feasibility assessment; what crew functions would it

make sense to replace with autonomous technologies? - Assessment of the impact of a reduced crew size on the ship’s

general arrangement and transport capacity.

• Benchmarking with state-of-the-art cargo ships

Icebreaker / (Arctic) evacuation shipDesign of a ship (either a newbuilding or a conversion) that is able to act both as an icebreaker, and as an evacuation ship in both Arctic and summer conditions• The motivation for the ship stems from the increasing

number of Arctic cruises• Design challenges include

- Arrangement of the ship’s general arrangement to allow for the protection of a large number (2,000- 4,000) of people considering basic comfort and hygiene requirements, requirements set by the harsh Arctic environmental conditions, etc.

- Benchmarking with state-of-the-art icebreakers to assess the ship’s cost-efficiency as icebreaker (To what degree does its “evacuation ship” function affect its cost-efficiency?)

- Assessment of the ship’s energy balance (e.g. icebreaking vs. heating)

• Requires strong input from the Winter Navigation course

Baltic Sea feeder systemDesign of a maritime transport system for continuous feeder operation on the Baltic Sea

• The motivation for the transport system stems from the assumptions that efficiency gains can be obtained by system thinking

• Design challenges/questions include:- Determination of ship/fleet parameters to meet an

assumed transport demand considering varying ice-conditions

- Assessment of the cost-efficiency of various possible concepts of operations (CONOPS), e.g. the use of icebreaker assisted ships vs. the use of independently operating ships

• Option: consideration of LNG as fuel• Requires strong input from the Winter

Navigation course

Norther sea Route Transit SystemDesign of a maritime transport system for

• Continuous feeder operation on the Baltic Sea- The motivation for the transport system stems from the

assumptions that efficiency gains can be obtained by system thinking

• Alternative: Transit operation along the Northern Sea Route (NSR)- The motivation for the transport system stems from the idea that

the NSR could be utilized for fast and cost-efficient transits transport of cargo between Northern Europe and the Far East

• Design challenges/questions include:- Determination of ship/fleet parameters to meet an assumed

transport demand considering varying ice-conditions- Assessment of the cost-efficiency of various possible concepts of

operations (CONOPS), e.g. the use of icebreaker assisted ships vs. the use of independently operating ships

Polar re-supply & research vessel

Design of a future Polar re-supply and research vessel utilizing new marine autonomous and robotic systems

• The new technology is utilized for improvements (when compared to state-of-the-art polar re-supply and research vessels) in the- Quality or scope of research work carried out

- Cargo carrying capacity (cargo volume or deadweight)

- Operability (the ability to operate in specific operating conditions)

- Building and/or operating costs

A multi-functional vessel to support to tasks for extracting, liquefying

and storing gas at sea. The ship is capable to support the tasks in

the farming of fish, support mining from seafloor. Design challenges :

• Ship/fleet parameters to meet an assumed transport demand

considering the supportive tasks of the service ship.

• Efficient and dynamic transportation of equipment, goods and

personnel to offshore platforms and fishing farms.

• Modern technology from the fishery, fish farming and offshore

industries (e.g. extraction of deep-sea polymetallic, mo-

lybdenum, zinc, lithium, platinum, germanium, etc.)

Nuclear container ship

• Drivers

New IMO sustainable goals to reduce 50% of emissions from

shipping by 2050

Fuel prices expected to increase considerably

Nuclear SMR technology is a valid option with practically very low

emissions

• Task : Design the concept of a modular SMR nuclear containership that

can sustain an accident without catastrophic consequences. The ship

should be able to operate freely at sea without intervention from port states

due to the mode of propulsion. Practically the ship should consist of a

propulsion module and a cargo module that can decouple outside of

territorial waters.

• Key challenges : concept design options, operational restrictions and

accidents.

• Driver : FIN government is planning to widen and

deepen the locks along the canal of Saimaa lake area

and extend the operational time to 11 months per year.

• Aim :

To design a multipurpose ice-capable cargo ves-sel,

with most of the volume reserved from bulk cargos

but also capable of carrying small amount of

containers.

To explore and fulfil the potential of inland waterway

transportation as a cost-effective and

environmentally friendly option to attract the interest

of transport companies.
