SRTP Complete 4 Day Deployment - May 2012

Continuing on from the successful grid connection last month, Scotrenewables Tidal Power Ltd. has forged ahead with their testing plan and have just completed a 4 day deployment of the SR250. Using the locally owned multi-cat 'MV Orcadia', the device was towed to site on Thursday morning and connected to their mooring at The Fall Of Warness. The device underwent a series of tests and remained on site until late on Sunday evening before being towed back to Hatston.

SR250 Successfully Exports Power to the UK National Grid - April 2012

In the latest of a series of onsite tests at EMEC Stromness based Scotrenewables Tidal Power Limited has successfully generated and exported power into the UK national grid for the first time. On the 18th of April the SR250 full-scale prototype was towed to EMEC Fall of Warness tidal test site and connected to it’s mooring system and electrical cable at slack tide ready for generation. The turbine began to generate and export power with the turn of the tide – in doing so the SR250 prototype has become the world’s first floating tidal turbine to achieve export of power to the national grid.

According to Barry Johnston, Scotrenewables Founder and Managing Director: “Yesterday’s successful export of power was a very significant day in the history of Scotrenewables which we have built up to by carrying out a series of intensive tow trials and onsite tests over the past number of months.  This achievement is a great testament to the efforts of the team. We still have a long way to go but we look forward with confidence to building up to longer term higher power tests over the course of the summer.”

SR250 Lift-in Completed in Advance of Further Testing - March 2012

On March 29th 2012 the SR250 prototype was lifted from it's stands on Hatston Pier back into the water. The lift-in followed a thorough inspection of the turbine by SRTP engineers. The model has now been given the 'all clear' in advance of an intensive period of testing at EMEC during Spring and Summer 2012. 

This phase of testing has already begun with SRTP successfully completing a 30 hour onsite fully grid-connected test on the 2nd and 3rd of April.

SR250 Lifted Harbourside for Annual Maintenance - February 2012

On Friday 24th Feb, the SR250 was carefully lifted out of the water onto stands at Hatston Pier to undergo annual maintenance. SRTP staff will hold an open day for members of the public and schools who may be interested in learning more about the device and the work of the company. The SR250 will remain out of the water for 3-4 weeks before testing continues. The team will focus on grid connection tests and longer term deployments for the remainder of 2012.

SR250 Put Through Paces in 1st Full-Power Tow Test - December 2011

A further testing milestone was achieved when the SR250 was put through its paces in a first full-power tow test. On 7th December the multicat MV Orcadia towed the SR250, north of Kirkwall harbour, achieving full-power of 250kW for the first time. Scotrenewables CTO Mark Hamilton stated “Tow trials allow us to simulate real tidal conditions in a controlled way to test all on board systems. Reaching fully rated power is a significant milestone for us and is testament to the hard work of all the team. The full-power test went extremely well and successfully demonstrated our floating turbine’s ability to produce power stably and efficiently.”

This full-power tow test marks the end of successful tow trial testing of the SR250. Early in the New Year the SR250 will be lifted onto Hatston Pier for a scheduled inspection period and fitting of some additional onboard instrumentation. While the model is out of the water at Hatston, Scotrenewables will be holding an Open Day (date to be confirmed) for members of the public and schools to come and visit the site to find out more about the technology and view the turbine up close. Anyone interested should get in touch with Scotrenewables Stromness Office. Following the inspection period the SR250 will be lifted back into the water in advance of more prolonged testing at EMEC through 2012.
