WAVE-TRICITY (W-T): Renewable energy test barge refit and refurbishment
Contract background:
A. The refurbishment and fit out of a 1940’s concrete water barge, that is partly converted as a house boat, for use as a trials platform.
B. Currently the original barge has had a wheelhouse, 2 access doors, 2 skylights, 2 stairways and approx. 18 glass bricks/panels fitted on the upper deck. The majority of the internal fittings have been removed although the wooden decks, some inbuilt furniture and some small water tanks remain. The main access positions have been highlighted on the original plan in additional documentation.
C. The trials platform will be used to mount the power generating equipment associated with wave energy convertor point absorbers.
D. An additional work stream will involve design support for the design of the full sized platform which will be manufactured on completion of the initial 2 year trails period.
E. This is a collaborative contract working with Wave-Tricity that will develop further as the trials progress. Numerous organisations will be involved in the design and testing of this innovative technology throughout the project which is part funded by the ERDF programme for West Wales and the Valleys through the Welsh European Funding Office.
F. Wave-Tricity office will be based in Pembroke Dock and as it will require close cooperation between parties the work should be carried out within the Pembroke area.
G. Ready for sea date is 28 Feb 2017. All refit work is to be completed by 10 Feb 2017 to allow sailing preparations to be carried out.
The work package will include but not be limited to:
1) Remove barge from water.
2) Remove all remaining fittings from all internal compartments. Clean internal\external and carry out detailed survey and report. (Note: It is estimated that a small quantity of asbestos is fitted in the barge up to a maximum of 100kg).
