SHAKING UP THE STATUS QUO:

For shipowners, the promise of electrification are compelling

It’s a time of revolutionary change as the world moves toward electrification. The marine industry is no different. At SPOC Grid Inverter Technologies, our power conversion technology and expertise in a broad array of energy storage chemistries help you build ships with smarter, better-performing hybrid power systems that burn less diesel fuel and create fewer carbon emissions.

 

WHY IT MATTERS:

Running your hybrid power system in the optimal range will reduce two of your major expenses: fuel consumption and engine maintenance costs. Burning less fuel also means you produce far fewer carbon emissions, helping you meet the increasingly stringent ESG demands of customers, regulators and port authorities.

WITH SPOC, YOU CAN EXPECT SUSTAINABLE OPERATIONAL AND ENVIRONMENTAL BENEFITS:

POWER CONVERSION:

At the heart of an efficient hybrid power system

 

OUR TECHNOLOGY MAKES IT POSSIBLE. OUR EXPERTISE MAKES IT WORK

The key to building effective hybrid power systems is the seamless integration of individual components and subsystems. And no two applications are the same.

 

IT’S ALL ABOUT THE GENERATOR

Our technology and expertise are not designed to replace your existing generator equipment. Instead, we make it smarter. We make it more efficient. We make it cleaner. We help it perform at its maximum efficiency.

 

FIRST, IT MEANS UNDERSTANDING THE TYPICAL LOAD

Only by understanding the operating profile of your ship can you design an effective and efficient power generation system. It’s the starting point that drives all subsequent decisions.

IT ALSO MEANS RIGHT-SIZING EQUIPMENT

Many industries, because of redundancy requirements, have traditionally factored in buffers when sizing equipment, in anticipation of worst-case scenarios. That is especially true with power generation equipment, which significantly increases capital investment. The result is that, under normal operating conditions, generator sets run lightly loaded, well outside their most efficient load curves. But lightly loaded generator sets are inefficient; they waste fuel, produce excess emissions, and have increased maintenance costs.

 

REDUCE YOUR CAPITAL EXPENSE

A hybrid power system allows you to size your generator sets by looking at the entire load profile, not by peak demand. Often this means the ship requires fewer or smaller units, and those generators run at their optimal load. In times of need, the inverter supplements the generators by instantaneously pulling from the batteries. The result?

Smaller, more efficient, smarter engines, running at their optimal load, burn less fuel and create fewer emissions.

REDUCE YOUR OPERATING COSTS

Generator sets are typically most efficient running at 70-80% load. This corresponds to ideal operating temperatures and fuel/air mixtures, which results in complete combustion. That means you burn less fuel per kilowatt hour of power produced.

SPOC’s DC bus platform is a stable, predictable, proven foundation for your hybrid power system

The path to creating a truly efficient power system for ships leads through a common DC bus, allowing for the efficient combination of the component elements.

THE DC BUS

Enables a host of benefits by tying together generators, shore connection, batteries and even alternative fuel sources into one modular system that can scale from the smallest service vessel to the largest container ship. It allows for maximum efficiency gains while increasing the flexibility of the system to accommodate future technologies.

 

INTEGRATE ADDITIONAL TECHNOLOGIES

A DC-based system allows for an infinite number of power solutions by integrating multiple technologies such as batteries, alternative fuels, super capacitors and even variable-speed generators.

 

CONNECT AT 50Hz OR 60Hz

Not all grid connections are the same. SPOC’s inverters allow you to convert power to your application’s frequency, keeping your power system stable and in perfect balance.

 

INSTANTANEOUS RESPONSE AND PEAK SHAVING

A stable and reliable power system is critical in any application. Understanding and responding to transient load requirements is essential. A hybrid system that incorporates both generator sets and energy storage allows your power system to respond to transient loads instantaneously with stable voltage. Batteries can be specifically controlled to deliver power during peak loads and to charge during periods of lower demand.

 

PROTECT YOUR EQUIPMENT

One important benefit of power conversion is that the inverter galvanically isolates your generator sets, protecting them from potential negative power flow.

 

MORE DATA. MORE INSIGHTS.

In addition to greater flexibility and efficiency, SPOC’s DC platform and inverters also provide more operational data to allow for optimized performance.

In the marine industry, ESG performance matters

Increasingly, financiers; insurers; regulators; and, of course, customers are linking profitability and sustainability to ESG metrics. It is a time when ship owners and operators either embrace ESG goals with sustainable strategies or risk getting pushed from the industry.

A MEASURABLE STRATEGY INCREASES ACCESS TO CAPITAL.
Companies with sound, funded ESG strategies, who measure their performance, have much greater access to capital.
LOWER SCOPE 1 EMISSIONS.
Today, lowering emissions is an important goal for almost all industries. Oversized generator sets, lightly loaded, waste fuel. Redundancy requirements also burn excess fuel and produce excess emissions.
Hybrid power systems cut down on fuel
BURN LESS FUEL. REDUCE MAINTENANCE. SAVE MONEY.
Reduce maintenance. Save money. We’ve said this already, but a hybrid power system uses less fuel than diesel generator sets alone. That by itself can significantly lower operating costs. Optimally loaded generators also require less maintenance, again saving money by extending the life of your equipment.
ESG GOALS ARE SMART BUSINESS.
Offshore customers increasingly make ESG metrics a key requirement in their potential partners, meaning in a competitive environment, the ships producing the fewest emissions have a strong competitive advantage.
