We are Green Ships AS

We like to see ourselves as a pioneering company at the forefront of sustainable maritime innovation. Our mission is to participate in revolutionizing the shipping industry by providing fossil-free fueling solutions that drastically reduce carbon emissions and environmental impact. As global trade continues to grow, the need for cleaner, more efficient marine vessels has never been greater. 

Green Ships AS is committed to designing and implementing cutting-edge technologies that harness renewable energy sources, such as hydrogen, biofuels, ammonium and electric power, to propel ships without reliance on traditional fossil fuels. 

What we do

Green Ships AS is a consultancy company involved with design and building of vessels which are optimized for a greener environment (reduced fuel consumption and reduced emissions such as CO2, NOx, SOx, Methane and PM). Green Ships AS has been involved with different types of vessels; offshore vessels, fast ferries, cruise ships, and specialized vessels such as drill ships, crane/accommodation barges and shuttle tankers. We are also involved in design of naval vessels. 

We offer consultancy for shipowners, shipyards, maritime equipment vendors, sub-sea contractors and finance institutions.Green Ships AS has also been involved as manager/owner of smaller fast ferries, and as minority owner in some ship owning companies.

Special features of Green  Ships AS vessels are:

Modern hull form with low resistance, improved operability and motion characteristics

Advanced hybrid power plants, normally based on diesel-electric/gas turbine with WHRS, along with battery/windmill systems

Use of advanced multi propulsion systems

Use of dual-fuel systems, combining diesel and/or LNG as required

Concepts and projects

GREEN SHIPS AS (NORWAY)

In all our projects listed below, we utilize a similar technology framework based on hybrid electric power plant systems. These systems incorporate a combination of the following:

  • Batteries
  • Fuel cells
  • Specialized diesel engines (compliant with IMO Tier 3 NOx emission regulations without the need for catalyzers)
  • Gas turbine generator sets (dual-fuel)
  • Units designed for fuel flexibility, capable of operating on multiple fuel types, including MDO, MGO, LNG, and ammonia/hydrogen
  • Wind energy integration

This approach ensures efficiency, sustainability, and compliance with the latest environmental regulations.

Overview of GS Naval Vessels: Corvette and Frigate 

Green Ships AS presents two advanced, multi-mission naval vessels:
 
1. GS 70m Corvette 
  Length: 70 meters

  Type: Fast, mono-hull, guided missile corvette
  Speed: Up to 40 knots
  Often referred to as a Littoral Combat Ship (LCS)

2. GS 110m Frigate 
  Length: 110 meters
  Type: Compact, multi-mission, guided missile frigate
  Speed: 30+ knots

Key Features (Common to Both Vessels) 


  Advanced Armament and Sensors:
     - Both vessels are equipped with state-of-the-art sensors and modern weapons systems.

  Propulsion and Power Systems: 
     - Both vessels utilize similar power and electrical plant configurations.
     - Each has 3 to 6 independent engine rooms and several separate control rooms.
     - Powered exclusively by reliable MAN diesel engines and ABB electrical systems 
         (no gas turbines or complex earboxes).
     - Propulsion is provided by waterjet units (e.g., MJP), eliminating vulnerable components 
         such as propeller shafts, propellers, and rudders.

Weapons Systems
Armament options include, but are not limited to: 
  1 × 76mm Super Rapid main gun
  32–60 Vertical Launch System (VLS) cells for various missile types (range: 40–200 km)
  Advanced Anti-Submarine Warfare (ASW) system with towed array sonar
  Helicopter deck and hangar (Frigate only)
  2 × 2 lightweight torpedo launchers
  20–30mm Close-In Weapon Systems (CIWS)
  2 × 4 anti-ship missile canisters
  1 or 2 MPLS (Multi-Purpose Modular Launch Systems) for up to 100 short-range missiles/rockets
  Additional systems as per customer requirements

Sensors and Electronics
Sensor packages to be defined in collaboration with the client and may include: 
  Long-range, multi-target tracking radars
  X-band and L-band radar options
  A variety of systems are available depending on performance, weight, and budget requirements

Environmental and Operational Efficiency 
  Hybrid propulsion systems for fuel efficiency and extended range
  Compliant with IMO Tier III NOx regulations at low speeds
  L​​ow CO₂ and methane emissions
  Designed for minimal crew requirements: 
          ​- GS 110 Frigate: fewer than 100 personnel
          - GS 70 Corvette: approximately 50 personnel

Cost and Procurement Considerations
Final pricing for the GS 70 Corvette and GS 110 Frigate depends on selected sensor and armament configurations, as well as the chosen shipyard. In general, modern naval ships have a cost breakdown of approximately 50% for the base platform and 50% for armaments and systems. However, due to the high-end equipment integrated into the GS vessels, the cost breakdown is closer to 40% platform and 60% systems. 

Estimated Base Costs: 
  GS 110 Frigate: Approx. EUR 100 million
  GS 70 Corvette: Approx. EUR 50 million
   
Production and Financing
Green Ships AS is in contact with several advanced shipyards, both in Norway and internationally. These yards, while not traditional naval contractors, specialize in complex vessels (e.g., offshore support ships, RoPax ferries) and offer competitive pricing with short delivery times. 

Financing solutions through private and state-backed maritime financing agencies can be arranged, including the possibility of leasing options for “grey” naval ships. 

Further pricing details and technical specifications are available upon request.
