Code of practice for the initial and periodic examination, testing and certification of diving plant and equipment
Summary
This code addresses the initial and periodic examination, testing and certification of all diving plant and equipment as utilised within the offshore diving industry.
The aim of the code is to provide a comprehensive reference source addressing the philosophy of the competent person and the examination, test and certification requirements necessary to meet agreed industry practice. This will apply anywhere in the world being:
- outside the territorial waters of most countries (normally 12 nautical miles or 22.22 kilometres from shore), or
- inside territorial waters where offshore diving, normally in support of the oil & gas or renewable/ alternative energy industries, is being carried out. Specifically excluded are diving operations being conducted in support of civil, inland, inshore or harbour works or in any case where operations are not conducted from an offshore structure, vessel or floating structure normally associated with offshore oil & gas or renewable/alternative energy industry activities.
This document is intended to assist the following, among others:
- manufacturers and suppliers of diving plant and equipment
- diving contractors commissioning new build diving systems
- personnel involved in diving operations
- staff involved in the maintenance, repair, test or certification of plant and equipment
- client and contractor representatives
- vessel owners and marine crews involved with diving operations
- all personnel involved in quality assurance (QA) and safety
- diving system auditors.
IMCA has included recommendations in areas where there is a difficult balance between commercial considerations and safety implications. It is recognised, however, that safety must never be compromised for any reason.
