Transcript of Pelamis

The Company Itself

Pelamis Wave power is the world's leading and by far most advanced company for wave power development
The company is based in the UK
Pelamis is a private owned business who has been able to make up to 75 million dollars in order to continue to succeed with development of Pelamis technology from a variety of financial and industry's
The world’s


export of electricity due to their use of offshore wave energy converter to an onshore grid network
The Supply and commissar of the world’s first multiple machine wave farm
Also Securing the UK’s first commercial orders for wave energy converters from utility customers E.ON and Scottish Power Renewables
Wave Power

History of
Pelamis Company
Founded in 1998 by inventor Dr Richard Yemm, Dr David Pizer, and Dr Chris Retzler
Goal was to create technology that uses the motion of ocean surface waves to create electricity.
Originally named 'Ocean Power Delivery', the company changed its name in September 2007
The Pelamis full scale prototype machine was tested at the European Marine Energy Centre between 2004 and 2007

The Pelamis is basically an energy converter that uses the motion of waves to produce energy
The machine in order to work needs to operate in depths of water greater then 50m
Installed 2-10km from the coast
The Machine is rated at 750kW
One machine can provide enough sufficient power to fuel over 500 homes
The Pelamis company has finished and developed six full models to date
Technology (Part 2)

The Pelamis machine is made up of five tube like sections linked to joints which allows the machine to flex in different directions. The Pelamis power machine floats semi-submerged on the surface of the water and faces into the direction of the waves.
As waves pass down the length of the machine and the sections bend in the water, the movement is converted into electricity from hydraulic power systems inside each joint of the machine tubes. Power is then transmitted to shore using sub sea cables and equipment.
Each of the power take-off units at the joints of the machine are identical
Effects on Environment

Company Claims to have the potential to be one of the most environmentally friendly sea companies to date
In the unlikely event that a leak occurs within a system, there are two levels of protection on all leak points, both of which would have to fail to allow water to flood to a point where fluid could escape to the outside environment.
A on board Modeling system lets company detect the smallest changes with the model at an early stage.
Not like the fuel tank of a passenger ship or an oil and gas ship, only very small quantities of transmission fluid are carried and this does not pose a threat to the marine environment
Effects on Environment (Part 2)

Unlike a vessel, where marine growth causes drag and can increase fuel costs, any increased drag to Pelamis due to marine growth is negligible.
Uses localized anti-fouling protection systems to protect key areas of machine like heat exchanger system
Wave Power: How it Works!
Naming the Company
The Wave Farm

A wave farm is a collection of machines in the same location that uses the generation of wave power electricity.
Wave farms can be either offshore or near shore
The Pelamis wave company invented the first wave farm located in Portugal- the Aguçadoura Wave Farm
The Aguçadoura wave farm consists of three of the Pelamis machines
Renewable vs

Of coarse the idea of using waves to convert energy is a Renewable idea!
Any naturally occurring, theoretically inexhaustible source of energy, as biomass, solar, wind, tidal, wave, and hydroelectric power, that is not derived from fossil or nuclear fuel is a renewable resource
Wave Power! (What is it?)

Wave Power is the transportation of energy through ocean waves.
The captured energy can be used for many specific advances such as electric generation, water desalination, and the pumping of water into reservoirs
Machinery able to use wave power is known as a wave energy converter
Wave power is the concept of the flux of tidal power and the steady motion of ocean currents.
Location of the Company
Pelamis's main offices are located in Edinburgh Scotland
Pelamis also has a small Operations and Maintenance team based in Orkney which oversee the operations of the two Pelamis machines currently under test at the European Marine Energy Centre
Pelamis snake - what company is named after and found in most tropical waters around the world
Pelamis is the world's first company to deliver electricity from offshore to the national grid (National Grid is an international electricity and gas company and one of the largest investor-owned energy companies in the world.)
Current electricity demand in the UK is as high as 36,120 MW or needs enough power to boil 14,448,000 kettles!!!
Why Wave Energy?

Has potential to be most environmentally forms of electricity generation
With resource distributed across globe- offers many countries the security of their supply
Waves can be anticipated one\two days in advance because of direct satellite measurements and meteorological forecasts which equal predictability and good network planning.
Wave Energy...


Mr. Spicer's class

Why Wave Energy (Part 2)
Very good for seasonal changes- regions where electricity demand peaks in winter given heating and lighting requirements (e.g. Northern Europe, Western Canada and North-West USA).
Waves are very reliable with their amount of power they produce - only a few times a year are waves to weak to produce electricity
