An arrangement for connecting a tidal stream turbine to a support structure on a sea bed comprises a socket including a member 7 which engages with a surface 10 of a male engaging element. The member 7 is movable relative to the socket wall when forced by the male element 10. The member 7 may have an annular inner engaging head, surrounded by a relatively flexible annular neck to allow movement. The male member may have two engaging elements 9 and 10, which engage with members 5 and 7 in the socket. The flexibility of the member 7 accommodates manufacturing tolerances in the length between elements 9 and 10. The engaging surfaces may be conical. There may be guiding portions of a softer, sacrificial material before each engaging portion (25, 26, 27, figure 5). |
