Diving bell cross-hauling is a technique used to get the diving bell closer to the worksite when the distance between the bell at its normal deployment position and the site makes diving operations either unsafe or impractical, even with the use of an extended umbilical.

The cross-hauling technique, whether on barges, diving support vessels, platforms or other structures, can be divided into two main categories - either the static line or winch-operated method. This note provides guidance on both methods.

The document refers extensively to more detailed guidance on examination, testing, certification and other requirements found in IMCA D 018 - Code of practice on the initial and periodic examination, testing and certification of diving plant and equipment - and IMCA D 024 - Diving equipment systems inspection guidance note (DESIGN) for saturation (bell) diving systems.

All diving projects need to be properly and safely management. An assessment of the general principles of the diving technique to be used should be carried out, as well as the needs of the particular operation. This guidance highlights the principles of cross-hauling operations, together with the relevant areas to be included in a project's risk assessments.
