To ask the Secretary of State for Transport if he will list all the collisions between (a) the Bowbelle and bridges, (b) the Bowbelle and other vessels, (c) the Bow Trader and bridges and (d) the Bow Trader and other vessels on the River Thames each year since 1981; and what was the total number of collisions on the Thames in each of those years.

The only collisions with a bridge recorded for the subject ships occurred in 1982, when Bowbelle made contact with scaffolding at Cannon street railway bridge, and in 1989 when Bowbelle struck the same bridge immediately after colliding with Marchioness. The information on other collisions and contacts is in the table; it covers all contacts including those with stationary objects as well as other vessels. The last column includes all types of vessel including small craft such as rowing boats.
