Top concerns for the marine sectorManaging marine efficiency and the environment

Challenges facing marine industry: Emissions reduction Improved fuel use Environmental impact of new builds Implementing energy saving technology

Challenges facing marine industryEmissions reduction – The facts

Recognised as cleanest form of transporting goods least damage per tonne of cargo

2007 global shipping industry emitted 1,046 million tonnes of CO2

3.3% of total global emissions

IMO predicts 250% rise in emission levels through sea transport growth

Challenges facing marine industryEmissions reduction – The facts

Ship exhaust emissions are industry's biggest polluter Shipping sector – so far – excluded from international

agreements Governments now want to include shipping in future

agreements By 2015 IMO implementing new sulphur emission targets

for marine fuel oil

Energy efficiency can reduce CO2 emissions by 25 to 75% for newbuilds and existing ships

Challenges facing marine industryImproved fuel use – The facts

Bunker fuel accounts for 50% of total transport costs Directly connected to crude oil prices - can only get more

expensive

Running auxiliary engines in port to create on-board power raises fuel costs

Creates emissions and negative health and environmental impact

Energy saving directly results in profit Take shipping company with 50% fuel costs and profits at 10%

of turnover: 10% decrease in fuel consumption increases profit by 45%

Challenges facing marine industryImproved fuel use – Some solutions

Shore-to-ship electric power supply helps eliminate: CO2, SOx and NOx emissions

particle discharge noise vibration

Ships shut down engines while berthed and plug into onshore power source

Power load is seamlessly transferred to shore side power supply

No disruption to on-board services Eliminates emissions to the local environment

Challenges facing marine industryImproved fuel use – Some solutions

ABB offers a complete, seamless and integrated shore-to-ship power solution

Safe and reliable power transfer from public electric power grid to ship

Complies with international standards

Challenges facing marine industryEnvironmental impact of new builds – The facts

IMO agreed to adopt mandatory energy efficiency design standards for new ships

Regulations demand: Energy Efficiency Design Index (EEDI) for new ships

stipulates a specific level of energy efficiency to be attained

Ship Energy Efficiency Management Plan (SEEMP) for all ships

Amendments to MARPOL regulations (Jan. 2013): Applies to all ships of 400 gross tonnage and above Ships built between 2015 and 2019 to be 10% more efficient

Rising to 20% between 2020 and 2024 Rising to 30% thereafter

New ships already contracted or under construction may be exempt

Challenges facing marine industryEnvironmental impact of new builds – The facts

Some cargo owners are already demanding voluntarily submitted environmental data

As part of the EEDI and SEEMP, IMO is considering vessels displaying their energy performance through these design and operation indices

Challenges facing marine industryImplementing energy saving technology – The facts

Cost-efficient technology to save energy exists Just not being implemented rapidly enough Industry faces an energy-efficiency gap Energy issues being given low priority Reasons for slow uptake are:

organisational failure lack of time shortage of competence no long-term energy strategy

Page 11: Energy efficiency and the environment

Challenges facing marine industryImplementing energy saving technology – The facts

Payback for energy-saving technologies – like drives and motors – can be within months

Identify applications that offer small saving from energy-efficiency measures

collectively they add up to significant total saving

Page 12: Energy efficiency and the environment

Challenges facing marine industryImplementing energy saving technology – The facts

Large energy consumers are: seawater cooling pumps chilled water pumps engine room ventilation fans

Often over-dimensioned to handle most extreme conditions Operate at full capacity even when demand is not high Flow control is often mechanical devices like bypass valves

and dampers highly energy inefficient

Page 13: Energy efficiency and the environment

Challenges facing marine industryImplementing energy saving technology – The facts

Lowering energy use reduces CO2, SOx and NOx emissions by reducing load on diesel generators

Single average size seawater cooling pump can save $29,000 and 117 tons of CO2 per year

Energy saving measures apply to: single ships or entire fleets planned newbuilds operating old vessels

Challenges facing marine industryImplementing energy saving technology – Solutions

Variable-speed drives (VSDs) Used to adjust motor speed according to demand Can reduce energy use by 50% Payback on equipment and installation, from fuel savings

alone, in under 1 year Large potential for retrofitting existing ships with new fuel-

reducing technologies Only around 2% of global fleet currently equipped with VSDs

for seawater cooling pumps 98% of fleet is missing opportunity for high fuel savings,

environmental and commercial rewards

Marine energy appraisal service Finds applications that benefit from energy-saving

technologies Identifies motor-driven applications that benefit from VSDs Payback often under 2 years

Marine energy appraisal – What’s involved Input data and documentation are collected during an on-

board survey including: Ship’s heat balance calculation Air balance calculation Layout of the systems Machinery datasheet Schedule of ship’s route Current system management Survey on board Vessel operational profile

Challenges facing marine industryImplementing energy saving technology – Solutions

Marine energy appraisal – What’s involved Energy appraisal is undertaken to find comparison between

power consumption and demand Final report verifies results including a return on investment.

Typical findings may include: Vessel has been designed for worst climate condition Motors of fans and pumps run only at fixed speed Current system is wasting up to 70% of energy

Cost proposal for implementing improvements is presented If accepted an installation site survey is carried Once agreed actual engineering and commissioning is

completed Results are verified to confirm actual saving

Energy Management System (EMS) Senior management needs to embrace environmental and

energy efficiency issues Provide resources to deal efficiently with company’s energy

issues Appoint an energy champion with agreed:

key targets responsibilities authority

Champion determines company’s present and expected energy use

Only then can accurate measurements, comparisons and follow-ups be implemented

Challenges facing marine industryImplementing energy saving technology – Solutions

Develop Energy Management System (EMS) EMS recognises proper procedures for measuring and

following-up results are as important as being able to plan and implement

EMS aims to: maximise profits minimise costs increase company’s competitiveness

EMS brings together employees that affect energy performance

EMS maps and analyses energy usage provides data to assess measures and decide on goals for energy

efficiency that are challenging but achievable

Energy Monitoring and Management tool (EMMA) EMMA impacts on fuel cost reduction EMMA gives complete visibility to energy production and

consumption performance EMMA helps operate a ship, several ships or entire fleet with

best possible energy efficiency and environmental responsibility

EMMA helps optimise energy-related processes, practices and decisions, from engine room to board room
