What is SWiG?

• Subsea Wireless Group

• Industry Working Group to:

– Promote interoperability between users of subsea wireless communications through the development of open standards

– Raise industry awareness, acceptance and integration of subsea wireless, through educational material and reference case studies

– Promote best practices & knowledge transfer across the industry

• Assess different wireless technologies– Radio communication

– Acoustic communication

– Free Space Optics communication (FSO)

– Inductive power

– Hybrid solutions

– their relevance to subsea operations

Subsea Technology NeedsTechnology Capabilities

GroupWireless Standards

• Identify industry uses for

wireless technologies

• Complete, reviewed and

updated as new operators

join the group

• Assess wireless

technologies and relevance

to subsea operations

• Identify current

applications

• Map technologies to needs

• Build on existing open

standards to develop new

standards that support full

interoperability between

hardwired and wireless

systems subsea


Wireless Standards

Create standards for:

• Radio

• Acoustic

• Free Space Optic

• Inductive Power

• Hybrid

The above standards are applicable to:

• Devices that support data, voice & video

transmissions

• Devices that support inductive

recharging/data transmissions

Radio standard, completed 2016

• Submitted to API 17F Sub-committee

• Now back with SWiG for review

Acoustic standard being developed

• NATO subsea acoustic standard (Janus) reviewed

• Final draft under review by SWiG members

Inductive power standard in progress

Next step: Free Space Optics standard

Ongoing: SWiGstandard document

• Define interface between SWiG wireless standards and devices

• Allows interchangeability of wireless systems

• Support an overall hybrid standard

Activities Outputs


Acoustic Standard Update

• Final review

• Standard covers interoperability of devices

• Provides a variable length packet structure to transmit payload data at up to 200 bps

• Transmit data, potentially images

– Allows applications to be developed using a communication channel, with consideration for reliability and security

as required

• May be used alongside proprietary communications for increased functionality and data

rate

• SWiGacoustic version 2

Innovation from a Standard

• Variable packet structure provides

flexibility

• Innovation on the application layer

– Security

– Networking

– Interface to assets

– Operate in parallel with additional

communication methods

7

Example Use Cases

– Riser Monitoring

– Seismic monitoring

– AUVs

– Environmental monitoring


Multiple Standards for Wide Area Network

• Acoustic long range low data

rate

• FSO / Radio for short range

high data rate

• Inductive for wireless power

transfer

• Wireless network of subsea

assets including vehicles

• Wireless network of subsea

infrastructure including vehicle

charging and position reference
