• Compliance checks of related equipment
• A survey after installation on board

Electrical Design

MSA works with every client to fully understand the needs and expectations for their vessel electrical projects.

MSA’s AMSA-accredited, Electrical Surveyors remain dedicated in maintaining a high level of technical knowledge, incorporating leading edge concepts and solutions for all facets of electrical design.

• We develop and provide AMSA Approved Electrical Drawings specific for your vessel.
• Review vessel or new build project’s electrical drawing package and make a determination on compliance to the applicable standards.
• Provide recommendations on electrical design to achieve client demands and efficiency.
• Determine electrical needs and location where the equipment will be on the vessel.
• Determine the battery bank size and location to determine the size of the fuses or circuit breakers for each branch of the electrical system.
• Provide an electrical general arrangement of the vessel to show where each item of electric equipment will be provided.

Prior to commencement of an electrical design or modification of an existing drawing package, MSA will meet with the client to obtain electrical needs and location where the equipment will be on the vessel. This information will ensure the drawing package is compliant and efficient.

MSA ensures the installation is in accordance with the standards applicable to the vessel:

• National Standard of Commercial Vessels, Part C5B, Design and Construction, Electrical
• The relevant requirements of AS/NZS 3000:2007 Wiring Rules 2007 (including all amendments and standards referenced within)
• AS/NZS 3004.2 Electrical Installations Marinas and boats. Part 2: Boat installations
