Bureau Veritas’ New Rule Covers Classification of Diving Support Units

Leading international classification society Bureau Veritas has issued a new Rule Note covering the Classification of Diving Support Units.

The Rule Note NR609 sets out requirements for vessels used for manned diving operations whether they are fitted with an air system for shallow diving or a complex saturation system for deep diving.

Pierre de Livois, Senior Vice President, Marine & Offshore, Bureau Veritas, says, “The demand for diving support units is strong, with an estimated order book of more than twenty new build vessels. Currently for these vessels a special procedure is applied with ad-hoc survey schemes and technical requirements. Several operators of Offshore Support Vessels have asked BV to develop classification rules to cover the special needs of these units and particularly the diving support capabilities of multipurpose support vessels (MPSV) using portable diving systems.

“The rule note addresses the requirements specific to units supporting professional diving including the installation of the diving plant on-board, the interface between the ship and the diving system and the description of the in-service surveys. Among the main issues dealt with are fire safety, electrical energy supply, emergency means of escape, communication means and storage of the oxygen used to enrich the breathing gas.”

The latest industry practices are adopted including IMCA recommendations regarding diving.
