Organization: ABS
Publication Date: 1 June 2023
Status: active
Page Count: 48
scope:

This document is intended to define classification requirements for the design, installation, and survey of electrical service platforms including substations as defined in Subsection 1/10 on bottom-founded and floating offshore electric service platforms.

This document contains requirements for

● Transmission substations where the transformation of the voltage level from an offshore power plant occurs. For example, transformation of 36 kV to 132 kV, or 150 kV or 220 kV to an onshore substation.

● The design, installation, and surveys (at manufacturer's facility, installation onboard, in-service inspections, annual, periodical surveys, etc.) of offshore substations, in areas of substation protection and control system, metering, remote monitoring, Supervisory Control and Data Acquisition (SCADA), communication systems, cybersecurity, fire protection systems, lightning protection, etc.

● Equipment and systems qualification such as energy storage systems (ESS), computer-based systems, power electronic converters, large power transformers, Medium Voltage (MV), High Voltage (HV) gas insulated switchgear equipment, circuit breakers for DC and AC systems, installed on the offshore electrical substations facilities.

● Fire and gas detection systems, public address/general alarm systems, obstruction/navigation lights, auxiliary systems, emergency source of power, etc. where required.

Export cables or transmission cables (aerial or subsea) to and from the electrical service platform are not within the scope of classification.
