AS 6947 sets the requirements for crossings of’ navigable waterways by overhead and submarine electricity infrastructure.
This Standard is intended for use by crossing controllers for the planning, design and maintenance of crossings.
This Standard shall apply to all nev crossings af’ter the implementation date.
NOTE: The Standard should also be applied to existing crossings.
This Standard does not apply to the following:
(a) Installation practices.
(b) Environmental considerations.
(c) Impact on public amenity.
(d) Extra low voltage or communication cables.
(e) Electricity infrastructure close to but not crossing navigable waterways.
Crossing controllers are responsible for adopting appropriate procedures to cover (a) to (e), above.
The principles and requirements within this Standard are able to be enhanced or supplemented, provided this results in equivalent or improved safety outcomes. 1.2 OBJECTIVES The objectives of this Standard are to— (a) promote the safety of vessels and their occupants on navigable waterways; (b) manage the hazards associated with crossings of waterways by electricity infrastructure; and (c) establish the minimum standards required for crossings of navigable waterways.
When planning a crossing of a navigable waterway, a formal risk assessment shall be
carried out in accordance with AS/NZS 4360.
The risk assessment should identify and consider the following:
(a) Potential hazards.
(b) The risks associated with those hazards.
(c) The potential circumstances under which the risks could arise.
(d) The consequences of the risks.
(e) The treatment options that can be applied.
The purpose of the risk assessment is to ensure that crossings are designed. constructed and maintained such that the overall level of risk is as low as is reasonably practicable, particularly in relation to risks associated with the safety of persons.
During the risk assessment process and prior to the construction of any crossing. the crossing controller shall liaise and consult with relevant stakeholders such as—
(a) waterway administrators including navigation, port and maritime authorities and local government: and
(b) boating associations and other maritime stakeholders.
This is essential to ensure that factors that may influence risk are properly identified and addressed.
2.3.1 General
The following are just a few of’ the many factors that may be considered during a typical risk analysis associated with a crossing.
2.3.2 Hazards
The hazard being assessed is the crossing of a navigable waterway by electrical infrastructure.AS 6947 pdf download now.
