This standard defines the requirements for operation and design of three phase subsea liquid filled motors and subsea gas filled motors with a minimum rated power of 375 kW and with rated voltages up to and including 13.8 kV. This standard includes induction motors, permanent magnet motors and machines having an integrated load (e.g. a pump or compressor). This standard is applicable to variable speed motors and to single speed motors (also called Direct On Line motors). Considering the unique operational environment, this standard specifies additional requirements while consolidating applicable requirements from API standard 541 (for induction motors) and API standard 546 (for brushless synchronous motors), as well as IEC 60034, NEMA MG1 or IEEE 112 that are appropriate for electric motors used in a subsea environment. The scope of the document excludes motors rated for nominal system voltages 1000 volts or less and subsea electric submersible pump (ESP) motors.

61886-1-2021
IEEE/IEC International Standard for Subsea equipment--Part 1: Power connectors, penetrators and jumper assemblies with rated voltage from 3 kV (Umax = 3,6 kV) to 30 kV (Umax = 36 kV)
This document is applicable to single and three-phase wet-mateable and dry-mateable AC connectors, penetrators and jumper assemblies with rated voltages from 3 kV (Umax = 3,6 kV) to 30 kV (Umax = 36 kV). This document relates to the requirements and tests for products in the \"as manufactured and supplied\" condition. This document is not applicable to requirements and tests for products that have been subsequently installed, deployed or retrieved.
61886.2-2023
IEEE/IEC International Standard - Subsea equipment - Part 2: Power transformers
This part of IEC/IEEE 61886 is applicable to three-phase and single-phase liquid immersed subsea power transformers (including auto-transformers) with at least one winding with rated voltages in the range 3,6 ≤ Um ≤ 245 kV and with rated power in the range 50 kVA to 300 MVA. The intention is to specify additional requirements that are not covered by the IEC 60076 series and IEEE Std C57.12TM series. It is the intention of this document that subsea power transformers be designed and tested either in accordance with the IEC 60076 series (IEC profile) or with the IEEE C57.12 series (IEEE profile). For subsea transformers where no winding has a rated voltage above or equal to 3,6 kV, this document can be applicable, either as a whole or in part. The mechanical design principles are also applicable for liquid-immersed reactors. Where the terms "subsea transformer" or "transformer" are used, this means "transformer assembly". Where required, it is stated whether transformer accessories like penetrators and connectors are included or not.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
61886.2-2023/Cor 1-2025
IEEE/IEC Approved Draft International Standard - Subsea Equipment - Part 2: Power Transformers - Corrigendum 1
Technical updates to the testing and installation criteria are made in this corrigendum. NOTE - this Corrigendum was incorporated into 61886.2-2023.
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
