Power, charging and compressed air for quay, harbour and aquaculture
Hybrid power that cuts diesel consumption on the feed barge. Mobile battery chargers and fast charging for quay and yard, even where the grid is weak. Battery storage and oil-free compressed air for reception and processing.
Aquaculture · Energy
Four figures from public sources. They show what is possible in the industry, not what your site will achieve. You work that out with your own figures.
The fast chargers are specified for operation from −30 °C to +55 °C, and the mobile battery chargers in containers from −30 °C to +50 °C. The hybrid stations deliver power down to −20 °C.
Coast and harbour set their own requirements. We clarify the protection for your installation in the quote. As an optional service, the equipment can receive extra surface treatment in our own workshop in Norway or Sweden, with a 25-year warranty on the treatment.
On-call phone around the clock, all year, and service partners throughout the Nordics. The equipment has remote monitoring, so many faults can be found and fixed without anyone having to go out to the feed barge or the quay.
From the vessel at the quay to the hatchery on land. One company for power, charging, batteries, compressed air and filters, with service around the clock.
Vessels
Electric and hybrid vessels need charging at the quay, often where the grid is weak. Slipways and workshops need compressed air and filters.
Most workboats burn most of their diesel while working at the pens. Calculate it
Aquaculture at sea
Power around the clock without shore power, with less diesel and noise. Compressed air and filters for feeding and operations.
Feeding uses the most energy, and many barges generate their electricity with diesel. See nine measures
Land
Facilities where the power must never fail. Battery storage as backup and against power peaks, and oil-free compressed air where the air meets the product.
After feed, energy is the largest cost in a RAS facility. Calculate oxygen
Shipyards and industry
Power for vessels, cranes and machinery along the quay, charging for trucks and heavy machinery, and compressed air for the workshop.
Most compressed air systems can save around 30 % of the energy costs. Calculate it
Every installation is different. The table shows where we usually start.

New · Image analysis
Ten test programmes that answer immediately. The figures in the fields are examples. Replace them with your own, and we will calculate precisely when you request a quote.
A generator running around the clock at low load, compared with hybrid operation where the battery takes the load and the generator only charges.
The battery takes the load. The generator runs fewer hours, and those hours it runs at a good load.
The solar panels alone save 567 litres of diesel and 1.5 tonnes of CO2 per year. Every step counts.
Calculated conservatively: all power from the generator goes via the battery. The solar panels are calculated as annual production, and most of it comes in the summer half of the year. Shore power is not included.
What does the diesel on the barge cost today, and what does the electricity that can replace it cost? Calculated the same way as DNV GL.
With these figures the electricity costs less than the diesel it replaces.
Calculated as in DNV GL (2018): one litre of diesel contains 10.06 kWh, and energy use is 67 % lower with shore power. Cable, substation and grid connection are not included. Where the grid is weak, a battery can take the peaks. If the grid is too far away, see Hybrid operation.
Most workboats burn most of their diesel while working at the pens. Here you can see what it means when the equipment on board gets electricity instead.
Electricity at the pens gives a lower energy cost with these figures. It also gets quieter at the pens.
The example is from DNV GL (2018): 100 kW for six hours a day, 280 days a year. DNV GL estimates that electricity for the work can cut up to 75 % of a workboat's diesel. This requires the barge to have shore power. If the electricity comes from the generator on the barge, the diesel consumption moves there. Cables and outlets are not included.
A vessel lying at the quay with its auxiliary engine running, compared with shore power or battery.
Shore power gives a lower energy cost with these figures. On top of that, the quay becomes quiet.
Applies to direct emissions from the auxiliary engine. Investment in the installation is not included.
Will the grid at the quay hold for the charging you need, or must a battery cover the gap?
The grid alone is too weak, but with a battery it works. The battery recharges between the sessions.
The grid is calculated as 400 V three-phase (√3 × 400 V × amperes). Losses and margin are not included. For comparison, the mobile battery chargers range from 203 kWh to 3,344 kWh.
From litres of diesel to tonnes of CO2, and what a cut in consumption means.
Calculated with 2.66 kg CO2 per litre of diesel or marine gas oil.
What does a plant save with lower pressure, less leakage and a variable-speed compressor? Calculated for the same amount of useful air as today.
Lower pressure, less leakage and the right speed give the same air with less electricity.
The numbers in the fields are examples. The saving depends on the age of the compressor, the working pressure and how much the air demand varies. The heat is calculated from the electricity the compressor uses after the measures, and only has value where the plant can use it. Take a photo of the compressor or fill in the form, and we will calculate for your plant.
How large a generator and compressor are needed to make the oxygen on site, and how much electricity does it take?
The 40 Nm³/h generator covers the demand of 37.6 Nm³/h. DAV-55 has a 55.2 kW motor and is chosen with a 10 % reserve.
Calculated with 1.43 kg per Nm³ of oxygen. The air demand is taken from DENAIR's table, at 8 bar and 20 °C. The electricity is calculated from the compressor's motor power at full production. Dryer, controls, investment and service are not included. Liquid oxygen can still be kept as a reserve.
The demand charge in the grid tariff is paid for the highest peak in the month. A battery that takes the peak lowers the bill.
The battery takes the peak, and the grid tariff is calculated from a lower power.
Simplified calculation. The demand charge and the way the peak is measured vary between grid companies. The battery must be large enough to cover the peak for as long as it lasts.
How long does a battery keep refrigeration, freezers, pumps and controls running when the grid goes down?
This is how long the battery keeps the critical load running without grid.
Simplified calculation with 95 % inverter efficiency. Actual time depends on temperature and load profile. The battery must be connected via an inverter with automatic changeover to work as backup power.
The figures behind it: 2.66 kg CO2 per litre of diesel and marine gas oil is calculated from the emission factor 3.17 kg CO2 per kg of diesel (see Miljødirektoratet's emission factors) and a density of 0.84 kg per litre. Consumption per kWh for the generator is taken from the datasheet. Efficiency and prices of diesel and electricity are examples, excluding VAT. The feed barge and the work at the pens are calculated with the assumptions in DNV GL's report Fullelektrisk fiskeoppdrett (2018, in Norwegian). The measures and sources are collected on the page Save energy.
The figures are taken from the datasheets. Power, battery, tank and voltage are adapted to your plant.
For feed barges, quays and plants without shore power. The control system uses the solar panels first, then the battery. The generator is the backup and charges the battery, and the switch between sources is not noticed by the load.
The solar panels on the roof give power without emissions and without noise. Every litre of diesel not burned counts for the environment. The solar panels are also a visible sign to customers and neighbours that the plant cuts emissions.

From 836 kWh the units can be supplied with an MCS outlet for heavy vehicles. The 203 kWh unit is on a trailer, the others are supplied in a container.
Chargers from battery-buffered 240 kW on a standard fuse to MCS charging at 1500 A.
A battery storage cuts power peaks, acts as a buffer where the grid is too weak and can be charged from solar panels. We supply batteries from several manufacturers and choose according to the plant, not the brand. Battery, inverter and charging can be delivered as one system with shared control.
Backup power for quay, workshop and plant. The controller starts the generator by itself when the grid goes down and switches back when the grid returns.
Compressed air for feeding, oxygenation and net cleaning, and oil-free compressed air where the air meets the product. We supply compressor, dryer and filter as one package, with tank-mounted machines and corrosion-protected tanks for operation by the sea.
| Series | Type | Size |
|---|---|---|
| DAV | Screw compressor, variable speed | 4–355 kW, 7–13 bar |
| DAV+ | Two-stage, variable speed | 22–355 kW, 7–13 bar |

The generator separates oxygen or nitrogen from ordinary air using molecular sieves (PSA). Two towers take turns producing and cleaning themselves, so the gas flows steadily. The gas is made where it is used. Liquid gas can still serve as a reserve when consumption peaks.
A complete plant consists of compressor, air tank, dryer and filters, generator, process tank and gas tank. We supply the whole package.
On request we build the whole plant into a container, ready to place on the quay, the feed barge or the site. The container is corrosion-protected for seawater and salt air by our own surface treatment department, with a 25-year warranty.

Globe Energy was founded by Ingemar Stenslaett. His father is from Lofoten and was a fisherman. So was his grandfather, and it has been that way for many generations back.
Equipment that stands on a quay or a barge must work when it blows, when it freezes and when nobody has time to wait. That is why Globe Energy has a dedicated focus on those who work by the sea.
We know what is demanded of people and machines in this environment.

It depends on how low the load is today. A generator running around the clock at low load has the most to gain. Use the test program "Hybrid operation" with your own figures for a first estimate.
It depends on the site. At sea, feeding uses the most energy, and many feed barges generate their electricity with diesel generators. On the page Save energy we have collected nine measures with figures and sources. Calculate with your own figures in the test bench.
From 203 kWh on a trailer to 3,344 kWh in a container, with charging power up to 2,400 kW and up to ten charging outlets. From 836 kWh they can be delivered with an MCS outlet for heavy vehicles.
Not necessarily. A battery between the grid and the charger charges gently and delivers high power when needed. Boost Charger can be connected to 32, 64 or 125 A.
The fast chargers are specified for operation from −30 °C to +55 °C and have enclosure rating IP55 (Boost Charger IP54). The mobile container battery chargers are specified from −30 °C to +50 °C. The hybrid stations deliver power down to −20 °C. We clarify the corrosion protection for each plant.
