U.S. NAVY Underwater Cutting & Welding Manual (S0300-BB-MAN-010).pdf

August 20, 2009 · Filed Under Mechanical & Industrial Engineering  · Tags: , , ,

Taken from Introduction: This manual is intended to provide information on the use of conventional techniques for cutting and welding metals underwater. It is written for the U.S. Navy diver who specializes in ship salvage and harbor clearance operations. It is not a procedural guide for certifiable welding used in pre-planned underwater ship husbandry applications.

Divers who perform underwater cutting and welding must have greater skill and stamina than those doing the same work topside. The success and speed of operations depend upon the conditions under which the diver must work because the underwater environment imposes numerous limitations and restrictions on the operator and equipment. The diver is often restricted to working for only a short time on the bottom, particularly at deeper depths. The use of correct techniques and equipment becomes extremely important in terms of work accomplished per hour. Diving apparel, great depth, adverse currents, low temperature, lack of visibility and unstable footing are all factors which make underwater cutting and welding difficult.

Whenever practical, cutting techniques are preferred over welding during ship salvage operations. For example, when wrecking in place is the salvage technique, a chain reeved through two holes cut in the hull and around a transverse frame is the preferred attachment method over a welded padeye.

Only personnel trained and qualified in underwater cutting and welding may be assigned to use the procedures and techniques described herein. Additionally, the procedures in this manual must be carried out in conformance with the U.S. Navy Diving Manual (NAVSEA 0994-LP-001-9010) and standard Navy safety practices. Appendix D covers safety in greater detail.
