A novel method of construction for tidal power barrages is proposed in which cellular cofferdams of diaphragm walling are built within temporary sand islands, allowing construction of the barrage units in the dry after the sand islands are removed. Much of the diaphragm walling is incorporated in the permanent structures. Different methods of forming the sand islands are described. Costs are derived for comparison with other methods of construction.
