Proven Technology Solutions for Onshore Power Supply (OPS)

OPS, short for shore power, is any technology that enables ships and other vessels to be supplied with electricity from the shoreside while moored at berths and stay for a lengthy time in ports, their main and auxiliary engines hence can be shut down. OPS also known as "Cold ironing" in naval terminology, Shore to Ship Power(SSP), Alternative Maritime Power (AMP) or Shoreside Electricity (SSE).

Since the early 2010s, eCap Marine (formerly known as HPE Hybrid Port Energy) as an innovative technology company with expertise in deploying and realizing alternative sustainable clean energy power supply solutions, either for shipside (onboard) or electricity supply on shoreside (onshore), has made it possible for shipping companies to reduce emissions. Those mobile OPS technology solutions were for cold ironing of container ships (PowerPac) and cruise ships (PowerBarge), providing them with onshore power as well as operational support on behalf of the contractee.

Therefore, eCap Marine has distinguished itself for already having many years of real OPS experience, either with the technology or with the operation of onshore power.

The Environmental Impact of Onshore Power Supply (OPS)

The majority of ships (marine engines) use traditional fossil fuels for cheap costs, causing severe ship emissions. Even with lower sulfur content like Marine Gas Oil (MGO) or Marine Diesel Oil (MDO), vessels still cause high CO2 emission (carbon dioxide) together with other harmful air pollutants with SOx, NOx, Soots and Particulates (particle pollution aka PM). Ships' own auxiliary engines also produce ongoing noises. Worsening the air quality in port cities and damaging the health of their inhabitants.

OPS is hence a vital measure to reduce emissions and improve air quality in port cities.

Green Initiatives of Port Authorities in Port Cities

The International Maritime Organization (IMO) has been setting progressive goals to reduce emissions and to improve air quality in port cities. In July 2021, the European Commission updated and proposed FuelEU Maritime, requiring all EU containership ports with annually over 50 calls, to be carbon-neutral by 2050.

Meanwhile, many EU ports are aiming for "Zero Emission at Berth", including Antwerp, Bremerhaven, Hamburg, Haropa Port and Rotterdam, jointly and proactively committing to enable maximal deployment of OPS by 2028 for the large container segment, to combat air pollutants at berths and for a greener, climate-friendly future.


Challenges of Onshore Power Supply (OPS)

While OPS technology can be a very effective solution to reduce ship emissions at berths,

  • it is not possible to furnish all berths with OPS installations, because the usual OPS system is just built for one berth and stationary
  • the local grid often cannot fulfil the energy demand of all vessel types

The ports and their port authorities are hence urging for more coordinated approaches to OPS technology, in order to reduce investments and operational costs (CAPEX & OPEX). It is essential to encourage innovation to overcome present technological challenges and to stimulate the shipping sector to equip their vessels to make use of OPS in multiple ports.


eCap Marine's innovative Alternative Maritime Power Solutions

More than just usual Alternative Maritime Power (AMP), eCap Marine's alternative Power Supply OPS Solutions stand out for being:

  • containerized & modularized, integrated with all required components, like safety system
  • compact and small footprint, but still efficient and powerful, achieving lower CAPEX and OPEX costs
  • semi/-mobile, hence flexible and high utilization, more advantageous than stationary OPS systems
  • guaranteed stable, decentral (off-grid), independent power supply
  • compliant with IEC standards and local laws & regulations
  • capable of generating silent, emission-free electricity or with significant emission-reduction
  • every system can be customized according to a particular application scenario, request and specification, thus being designed and configured individually
  • able to deploy various fuel sources, either using green hydrogen fuel as H2PowerPac, battery storage as Battery PowerPac, or combustion engine as LNG PowerPac (Liquified Natural Gas), or LBG PowerPac (Liquified Bio Gas) or other gasiform green alternatives fuels
Energy Sector Triangle

With solid technology know-how and real-life operational experiences, eCap Marine will work closely together with clients – from concept, design, construction and to the final commission and implementation.

FAQ - Frequently Asked Questions

What is Shore to Ship Power?

Shore to Ship Power is electric power provided from the shoreside (grid or other sources) to ships while docked at berth and staying in ports.

What is On Shore Power Supply(OPS)?

Onshore Power Supply is any technology which enables terminal operators to supply shore-based electricity to incoming vessels when mooring at berths, thus their main and auxiliary engines can be shut down - it is also known as "Cold Ironing" in naval terminology, Alternative Marine Power (AMP) or Shoreside Electricity (SSE).

What are the benefits of Onshore Power Supply(OPS)?

Onshore Power Supply is an effective measure for port cities and their port authorities to achieve climate objectives, quickly improve the air quality in ports and protect the health of port city inhabitants. Vessels & Shipping companies as End-Users can fundamentally contribute to:

  • Reduce Emissions: of not only CO2 (carbon dioxide), but also other harmful air pollutants like SOx, NOx, Soots and Particulates significantly
  • Eliminate Noise: from ships' engines
  • Local community benefits
  • Innovation and Image
  • Environmental Regulations Compliance
  • Energy Efficiency & Costs Saving: modern electricity generation and fuel sources are much more efficient and sustainable than conventional marine engines and save CO2 Emission taxes
  • Reduce "Wear and Tear": ships' engines can be shut down while in port, thus extending their lifespan

What is Shoreside Power?

Shoreside Power means the electricity is provided by the shore-bound infrastructure, to the vessels docked at berths in port.
