Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13628-8 was prepared by Technical Committee ISO/TC 67, Materials, equipment and offshore structures
for the petroleum, petrochemical and natural gas industries, Subcommittee SC 4, Drilling and production
equipment.

Introduction
The part of ISO-13628 has been prepared to provide general recommendations and overall guidance for the
designa and operation of remotely operated tools comprising ROT and ROV tooling, used on subsea
production systems for the petroleum and natural gas indsutries worldwide.
Specific design requirements are used where a standard design or operating principle has been adopted in
the industry for a period of time. Requirements valid for certain geographic areas or environmental conditions,
are included where applicable.
The functional recommendations for the tooling systems and interfaces on the subsea production system
allow alternative solutions to suite field specific requirements. The intention is to facilitate and complement the
decision process rather than replace individual engineering judgement and, where requirements are non-
mandatory, to provide positive guidance for hte selection of an optimum solution.

Remotely operated tools and interfaces on subsea production
systems
1 Scope
This part of ISO 13628 provides recommendations for development and design of remotely operated subsea
tools and interfaces on subsea production systems in order to maximise the potential of standardising
equipment and design principles.
This part of ISO 13628 does not cover manned intervention, vertical wellbore intervention, internal flowline
inspection, tree running and tree running equipment. However, all the related subsea ROV/ROT interfaces are
covered by this standard. It is applicable to the selection, design and operation of ROTs and ROVs including
ROV tooling, hereafter defined in a common term as subsea intervention systems.
Also, the standard covers subsea intervention system interfaces on all parts of a subsea production system.
Intervention systems used for internal wellbore intervention, and the ROV system itself are not part of the
scope of this standard.

For the purposes of this document, the following terms, definitions and abbreviated terms apply:
3.1 Terms and definitions
3.1.1
functional requirement
minimum criterion which should be satisifed in order to meet a state objective or objectives
NOTE Functional requirements are performance oriented and are applicable to a wide range of development
concepts.
3.1.2
guideline
recommendation of recognized practice to be considered in conjunction with applicabel statutory requiremtns,
industry standards, standard practices and philosophies
3.1.3
manufacturer

3.1.5
remotely operated vehicle
ROV
free-swimming or tethered submersible craft used to perform tasks such as inspection, valve operations,
hydraulic functions and other general tasks
NOTE ROVs can also carry tooling packages for undertaking specific tasks such as pull-in and connection of rigid
spools, flexible flowlines, umbilicals, and component replacement. Alternatively modules or tools may be deployed by
crane and mated with the ROV subsea.
ROVs are grouped within the following main categories:
OBSROV – (IMCA class I & II) These vehicles are small vehicles fitted with cameras/lights and may carry sensors or
inspection equipment. They may also have a basic manipulative capability. They are mainly used for inspection and
monitoring.
WROV – (IMCA class III) These vehicles are large ROVs normally equipped with a five-function grabber and a seven-
function manipulators. These commonly have multiplexing controls capability that allows additional sensors and tools to be
operated without the need for a dedicated umbilical system. WROV are split into two classes: medium WROV and large
WROV depending on their defined workscope. WROVs can carry tooling packages to undertake specific tasks such as
tie-in and connection function for flowlines, umbilicals and rigid pipeline spools, and component replacement.
3.1.6
primary intervention
all work carried out during the scheduled intervention task
3.1.7
secondary intervention

4 Subsea intervention concepts
4.1 General
4.1.1 It is the intent of this standard to take a system wide approach to the design and implementation of
subsea intervention.
4.1.2 A subsea intervention system typically includes the following componets:
a) tooling for dedicated intervention tasks;
b) complimentary equipment (tool basket, guideposts etc.);
c) deck handling equipment;
d) control system;
e) deployment/landing equipment;
f) guidance and entry equipment;
g) ROV spread interface with equipment and tools.
4.1.3 There are several methods to ensure safe and efficient guidance of the subsea intervention system
to the subsea work site. Typical methods include:
a) surface guidewire systems;
b) guidelineless systems;
c) subsea deployed guidewire systems;
d) thruster assisted systems;
e) ROV assisted guidance.
4.1.4 The selection of equipment and intervention methods should be decided when establishing the
intervention strategy. (see subclause 4.6).
4.1.5 Common recommendation for the subsea intervention systems should be used as far as practical.
However specific recommendations for ROV and ROT systems and their subsystems are included in separate
chapters where design or operational requirements require as such.
4.1.6 Design of subsea systems and associated remotely operated tooling system in a optimum manner, is
dependant on a system design approach. The main focus areas in this respect are standardisation of
interfaces, equipment and intervention methods. Subsea intervention systems should be designed in parallel
with subsea production systems to allow for intervention friendly solutions for the life of field. The specification
covers tooling design, design of intervention interfaces on the subsea equipment, and guidelines for
implementing intervention friendly designs.
ISO/WD 13628-8
4.1.7 The design should focus on the safe and efficient handling including deck handling, operation and
maintainability of the subsea tools and interfaces. System for easy testing after mobilisation should be
provided.
4.1.8 The standards for the selection and use of remotely operated tooling interfaces have generally
selected one interface for a specific application. The inclusion of a particular approach or recommendation
does not imply that it is the only approach or the only interface to be used for that application.
4.1.9 In determining the suitability of standardization of remotely operated tooling system interfaces for
installation, maintenance or inspecti
