INTRODUCTION 

• The Pelamis Wave Energy Converter is a technology that uses the motion of ocean surface waves to create electricity. 
• This device is known as a ‘POINT ABSORBER' and can effectively focus energy from a wide area by interacting with an area of waves. 

PRINCIPLE 

• The waves being created by the progressive transfer of energy from the wind as it blows over the surface of the water. 
• The cylindrical structure of the converter joints is moved due to the action of waves of the sea and thereby creates energy. 

CONSTRUCTION

• —The Pelamis Wave Energy Converter is a semi-submerged device, composed of cylindrical sections linked by hinged joints. 
• —Each of the machine is 150m long and 3.5m in diameters and weigh about 700 tonnes of carbon steel.
• —A single device is composed of four articulated sections joined by three power modules.

OPERATION

• —The wave-induced motion of these joints is resisted by hydraulic rams. 
• —As waves moves the joints up and down and side to side, hydraulic ram moves according to it which pumps high pressure oil to the hydraulic motor. 
• —The hydraulic motors drive electrical generators to produce electricity. 
• —The generated electricity is transmitted through power sea cable.

SUBSEA POWER CABLES

• —Power from all the joints is fed down a single umbilical cable to a junction on the seabed. 
• —Several devices can be connected together and linked to shore through a single seabed cable.

—PROPOSAL FOR INDIA

• —The country that presently use the pelamis are Portugal, Ireland, France, Spain. 
• —Estimated amount of pelamis is about 2.25MW which currently meet the annual demand of 1500 family. 
• —In India the current demand is more now a days so if we propose this pelamis in INDIA the current demand can be easily reduced.

ADVANTAGES

• —No maintenance carried out at offshore site 
• —100% available technology 
• —No offshore intervention required 
• —'Hands Free' operation 
• —Lowest kWh costs in the market 
• —High return potential
