Nuevo aerogenerador portátil que se instala de forma rápida en la grúa de un barco para suministrar energía renovable


Oferta Tecnológica
Una pyme irlandesa del sector de energías renovables ha desarrollado el prototipo de un aerogenerador marítimo (nivel de preparación tecnológica 7) adaptable y portátil para barcos grandes y buques mercantes. Este aerogenerador utiliza la grúa del barco como mástil y su principal función es sustituir el motor diésel en períodos de inactividad. El prototipo ha sido probado y la tecnología se encuentra en la última fase de desarrollo. La empresa busca socios con el fin de establecer acuerdos de comercialización, joint venture, fabricación y cooperación técnica.


Innovative portable wind turbine that can be quickly mounted to a ships crane to provide renewable energy for the vessel
An Irish SME in the renewable energy sector has developed a prototype marine grade wind turbine (Technology Readiness Level 7) that is adaptable -Y- portable for large boats -Y- commercial ships. It utilises the existing ships crane as the turbine mast and its main function is to replace the diesel generator during downtime. The SME would consider mutually beneficial partnering arrangements including commercial, joint venture, manufacturing agreement and technical co-operation agreements.
The Irish SME specialises in the renewable energy technology area and has developed this innovative portable wind turbine which can be adaptable and portable for large boats and commercial ships.

Many vessel owners have no viable alternative but to use expensive and environmentally harmful fossil fuel electricity generators during periods of downtime. This results in a range of problems however this wind turbine offers a significant opportunity for a renewable alternative as researched by the company.

For example;
Emissions: Fossil fuel generators produce harmful emissions and can be avoided. The company´s research has shown this is not a consideration factor for ship owners, however it is a significant factor for higher level stakeholders in the shipping industry such as ports, policy makers and administrative bodies. This has led to the introduction of Emission Control Areas.

Fuel costs and regulations: Despite recent downward trends, fuel is a significant operating cost for vessels and is expected to return to historical levels in the medium term. Furthermore, regulatory action to cut emissions added to the economic problem for vessel owners. Under the Marine Equipment Directive for lowering emissions, global governments (US, Canada and the EU) have enforced emission controls in emission control areas. This effectively forces vessels to install expensive exhaust cleaning technology or switch to lower emission fuels which can be double the price of standard marine fuel. Similarly running a diesel generator is not only costly from a fuel end, but also from a maintenance end. The generators must be overhauled at set intervals, which is a large, recurring cost to the vessel owner.

Noise: Diesel generators can be extremely noisy and can interfere with crew well-being during rest and communications during operations.

Alternatives: Alternative energy technologies to retrofit commercial vessels are limited; commercial scale turbines are not available in the market and many alternative technologies are prohibitively expensive and only suited for large vessels.

The SME´s approach is to develop a portable wind turbine with innovative characteristics that is of a larger scale of anything available on the market for ships today. The innovation is unlocked due to the portability of the wind turbine, which can be quickly assembled and disassembled around the times it is required.

Deployment of a turbine on the ships existing crane is more cost effective, technically more straight forward and allows for deployment of significantly larger turbines to any ´fixed mast´ alternative.

Deployment using the existing crane allows for the turbine to be taken down when the ship sets off again, which would otherwise create drag and require the vessel engines to work harder.
There are up to 134,000 suitable vessels in the world which would have a crane on board and which can benefit from the renewable energy technology.

The SME is interested in a number of agreements in the area of commercial agreement, joint venture agreement, manufacturing agreement -Y- technical co-operation agreement. These agreements can be a mix aligned with the SME´s strategy and also more pertinent discussions will take place when expressions of interest are ranked to accept suitable potential partners.
Advantages and Innovations:
These include:

Power: The wind turbine will connect into the vessels electrical systems providing a secondary power source for heat, light, TV etc. It will be available in 5kW-20kW power capacity sizes which should meet the needs of the majority of vessels´ requirements during downtime.

Existing crane: The unit is deployed using the existing on-deck crane equipment. The crane boom becomes the turbine´s tower which can be moved into an optimum wind position. The use of the existing plant and machinery infrastructure makes the product more cost effective, allows the turbine to be taken down and allows for significantly larger turbines to be deployed.

Quick connect system: The wind turbine will connect to the crane using a specially designed quick connect system removing the requirement to manually handle the wind turbine.

Detachable blades: The design features detachable blades which have been designed for speed of deployment and to facilitate a minimal storage space requirement.

On-deck storage: When not in use the turbine, including the blades, will be stored on deck in a cradle specially designed to occupy minimal space.

Marine grade: The wind turbine will be a robust piece of equipment and designed and manufactured in line with its intended use in a harsh marine environment.

Safety is a primary consideration of the design and includes features such as automatic turbine lock to prevent the turbine from spinning until it is in the deployed position.

Other advantages in brief;
- Reduced fuel costs and emissions.
- Reduced generator servicing costs.
- The SME is targeting an economic payback for customers of 2 to 4 years (exact payback is dependent on downtime frequency, fuel costs and efficiency of the existing auxiliary generator).
- 20-year design life.
- Government grants and supports available in many countries.
- Green credentials and sustainability.
