IEC TC 18Electrical installations of ships

and of mobile and fixed offshore units

Scope of IEC TC 18:

To prepare standards for electrical installations and equipment of

ships and of mobile and fixed offshore units, incorporating good

practice and aligning as far as possible existing regulations and

IEC Publications. The standards will chiefly concern:

a) factors promoting the safety of ships and of mobile and fixed offshore

units;

b) factors promoting safety of life.

IEC TC 18 has 20 participating countries and 10 observer

countries

4/13



TC 18 has one subcommittee, SC 18A, with the scope:

To prepare international standards for cable construction and

performance promoting the safety of ships and of mobile and

fixed offshore units

SC 18A has 20 participating countries and 11 observercountries

5/13



TC 18 is mainly a system committee.

Existing standards are to some extent giving constructional

requirements to products.

When revising existing standards and preparing new ones,

reference is to the extent possible made to product standardsprepared by other committees, in accordance with the System

Approach philosophy.

6/13



The following standards relating to offshore installations are issued by

IEC TC 18 under the general title Mobile and fixed offshore units

Electrical installations:

IEC 61892-1 General requirements and conditions

IEC 61892-2 System design

IEC 61892-3 Equipment

IEC 61892-4 Cables

IEC 61892-5 Mobile units

IEC 61892-6 Installation

IEC 61892-7 Hazardous areas

The standards are referring to other relevant IEC and ISO standards

7/13



IEC TC 18 has liaison with IEC TC 31 and ISO TC 67

IEC TC 31 is responsible for the general standards for area classification and explosion

protected equipment. TC 18 is making reference to several of these standards in the

TC 18 standards

ISO TC 67 is responsible for materials, equipment and offshore structures for

petroleum, petrochemical and natural gas industries

ISO TC 67 is referring to IEC standards from both TC 18 and TC 31 in the TC 67

standards

IEC TC 18 is referring to several ISO standards in the TC 18 publications

IEC TC 18 has liaison with IMO

The IEC 61892 standards are referenced in the IMO 2009 MODU CODE

According to OGP report No. 426 Regulators use of standards, theIEC 61892 standards are referenced by 3 regulators (Denmark, Norway

and United Kingdom)

The IEC 61892 standards are recognized and widely used by oil

companies and major drilling contractors

Some ISO TC 67 standards of special interest to IEC

TC 18:

ISO 13702 Control and mitigation of fires and explosions on

offshore production installations

ISO 13628-5 Subsea umbilicals

ISO 10418 Basic surface process safety systems

ISO 19901-7 Stationkeeping systems for floating offshore

structures and mobile offshore units

ISO/CD15551 Electric submersible pumps

Split of responsibility between IEC and ISO:

IEC is responsible for electrical and electronic engineering

ISO is responsible for other fields

Cooperation between IEC and CENELEC is covered by theDresden agreement

Future CENELEC TC 18

Due to the initiative taken by the EU commission to prepare European

Standards for equipment used in the oil and gas industry Norway, who

holds the Reporting Secretariat of CENELEC TC 18 has proposed to

establish a CENELEC TC 18, with the same scope as for IEC TC 18, but

with an addition for Subsea Equipment.

10/13

Initiative from the European Commission

According to 2010 2013 Action Plan for European

Standardisation, dated 8 July 2011 the following

standardisation mandates are planned:

Mandate(s) to CEN and CENELEC for the development of

harmonised standards supporting the relevant EU productsafety legislation (Machinery, Pressure Equipment and ATEX

Directives) for equipment used in the offshore oil and gas

industry

11/13

Proposed CENELEC TC 18 Structure and

Scope

The CENELEC TC 18 structure will be based on the work structure of

IEC TC 18, and will be expanded to include systems and equipment in

the Oil & Gas offshore industries not part of the present IEC TC18

standards

This includes not only the integrity of non-topsides installed subsea equipment part of

offshore drilling and production units, but also the interaction of topsides facilities and

subsea equipment.

CENELEC TC 18scope as per IEC TC 18 (ships and mobile and fixed

offshore units)

CENELEC TC 18A - code used by IEC SC 18A (work assumed to be

adopted by parallel voting on IEC SC 18A standards)

CENELEC TC 18CNew, draft title:Subsea equipment

10


12/13

CENELEC SC 18CSubsea equipment

Subsea systems, including all seabed installed and

downhole power and control, interacting with topside

and shore based facilities power and control

systems.

Addressing subsea electrical loads, such as:

Motors for pumps and compressors,

Direct Electric Heating for pipeline flow assurance,

Subsea controls - with elements instruments, sensors,

controllers, modem communication all linked to the topside units

power system and control gear, part of crew operations.

The applicable choice of transmission medium for power and

signals (galvanic/fibre/radio/acoustic/pulsed) will be site specific

and according to functional requirements; design will be

subsequent to existing ISO/IEC technical standards and

engineering practises. 11


13/13

Emergency power - some new ideas

Traditionally emergency power has been generated

locally by separate generator(s)

Generator will shut down automatically upon gas in the air

intake

Emergency power provided by functionality of an

alternative power source, which by design is not

exposed to gas as autonomous combustion driven

generators on board would be

Cable from shore or from another installation

Relevant equipment (transformer and switchgear) can be

located in room without access from the outside, i.e. reduced

risk of gas ingress into the room.
