Shipping permit: enabling operators to
transition to low/no CO 2
-maritime emissions
To cut emissions, reduce noise, and increase reliability, Bastø Fosen decided to electrify its ferry fleet
With hybrid ship propulsion supported
by its digital portfolio,
Siemens Energy enables the transition to
zero CO 2 emission and energy-efficient
autonomous ship operation by enabling
vessel owners to meet sustainability targets
and comply with IMO 2023.
The shipping industry is under massive
pressure to decarbonize and reduce
greenhouse gas (GHG) emissions. From 1
January 2023, the International Maritime
Organization (IMO) will adopt new
measures to its initial GHG strategy
requiring vessels to document a reduction
in GHG emissions, adding carbon to its
previous focus on sulphur emissions. This
means that just a few months before the
‘harbour door’ closes, tens of thousands
of vessels are believed still to fall short of
the minimum requirements. Therefore,
operators must install retrofit technologies
or build new replacement vessels
that comply with tightening targets.
The value of the goal is clear: to reduce
the carbon intensity of all ships by 40 %
by 2030 (cf. 2008). However, these
changes create challenges and opportunities
for vessel owner/operators seeking
compliance. They also bring much
uncertainty – for example, it is still not
yet clear what the penalties for non-compliance
will be. Also seriously lagging are
the millions of decisions that support the
owner/operators in making the necessary
changes: from a legislative and subsidiary
framework to clear economic models to
aid decision making.
The IMO has yet to set a net-zero
emissions target, but many individual
ocean shipping companies already have,
including ferry companies. This continues
a trend more broadly experienced
through transportation – companies are
making progress on their sustainability
strategies without being pushed too hard
by policy. This is likely because they recognize
that sustainability is one of many
benefits.
For example, the world’s largest plug-in
hybrid vessel, »Color Hybrid« (owned by
Colour Line), set a new global standard
for environmentally friendly ships.
Among the innovative and eco-friendly
solutions that make this an important
milestone project for the maritime cluster
is its hybrid ship propulsion based on the
BlueDrive PlusC system from Siemens
Energy. This system makes vessels safer,
more efficient, more profitable, and more
environmentally friendly.
To cut emissions, reduce noise, and increase
reliability, Bastø Fosen decided to
electrify its ferry fleet. Operating on Norway’s
busiest crossing, the company’s allelectric
ferry, »Bastø Electric«, is the largest
of its kind. Bastø Fosen’s electrification
investments – with large battery
packs and fast-charging systems
from Siemens Energy – mean the company
can reduce its CO 2 emissions by
75 % in 2022 and reduce diesel consumption
by six million litres annually.
Hybridization is the first step
toward zero emissions
Today, many vessel types are beginning to
operate in hybrid: diesel, battery, and
e-Fuel. While this may be necessary for
the interim, it is not ideal long term to optimize
energy efficiency while reducing
GHG emissions. Such vessels include offshore
windfarm vessels (installation &
service); ferries and passenger vessels; offshore
oil & gas support vessels; RoPaxvessels;
tugs; cruise vessels; short sea shipping;
research vessels; and shuttle tankers.
All these vessel types are within the midsized
vessel segment (40–200m), where
