BCTQ attended on board Oil Fuel Hulk C77 lying afloat at Pembroke Dock, to carry out an "afloat" condition survey. Based on this initial survey, the decision was made to reconstruct the vessel to its 1862 condition.
BCTQ further advised on the towage of the vessel to Hartlepool and were retained throughout the period of reconstruction of H.M.S. Warrior.
