MEC-E1004 Principles of Naval Architecture
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

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
Requires strong input from the Passenger Ships – course

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

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.
