Innovation in ROV Peripherals Norwood Hall, Aberdeen, Friday 6th September

Introduction

• ROVs are being asked to carry out more and more tasks. They rely on Peripheral

devices to complete most of these complex tasks. I have chosen four Innovative

products for discussion today.

• Multiplexers

• Seebyte

• 3D Lasers

• Tool Changer

Multiplexers The heart of ROV peripheral configuration

The Issues

• Increasing number of sophisticated power-hungry digital ‘broadband’ survey

peripherals.

• Full multiple HD video camera requirement.

• Increasingly accurate position and attitude/inertial sensors.

• Dual or triple configuration ultra high-resolution Multibeam 2D and 3D sonars.

• No sensor latency, deeper water, system diagnostics, remote control.

• Mixture of Ethernet, fibre, RS232/422/485, comms and protocols

• Ability to work in 3000m + of WD.

The Heart of ROV Survey Sensors

iXBlue ROVINS

iXBlue PHINS DVL

R2Sonic 2024

Bowtech Surveyor Pro

TSS 440 Pipetracker

Coda Echoscope 3D Real Time Sonar

Valeport Mini SVS

Reson SeaBat 7125 Seebyte SeeTrack CoPilot

The Challenge

• Streaming of multiple peripheral data strings

• Powering an array of broadband digital

survey sensors

• Minimum signal connections to ROV

• Single power connection to ROV

• Plug and play

The Solution

The Solution

A single compact multiplexer that ...

• Operates on a single mode fibre and that can power and operate a variety of

sensors simultaneously.

• Connects via a single connector, compact, rugged, lightweight, and proven.

• Can operate at 3000m + depths.

• Can diagnose peripheral/sensor problems.

• Enables extended survey sensors/peripherals to be operated on an ROV.

• Enables the ROV to perform multiple survey and inspection tasks from a single

launch.

Survey & Tooling Skid

• ROV docks onto skid on deck

• Single connection

• Multiple sensors

• No requirement to install sensors

individually – saves hours!

• All sensors powered and run through

single Mux and single connection.

• Reduce failure risk of multiple

connectors.

Camera boom Dual Multibeam arms

Boom Arm TSS 440 Pipe tracker

The Features

• Can extend and expand the capability of an ROV by being able to accommodate

more sophisticated sensors and survey peripherals.

• Reduce incidence of launch and recover to change out sensors.

• Reduced time = reduced costs of ROV Support vessel, or barge, crew etc.

• Fibre drop-outs? No worries, no requirement for any link synch time as comms

are immediate after (re)-connection.

• Real Time data ,no latency

• Fully Time stamped

The Features Cont

• Compact and Lightweight

• Bandwidth – not a limiting factor

• Oh....did I mention that it’s truly plug and play

• ...all running on one single fibre

Laser 3D

Workflow based on Clarity Long range: 15+ meters

Water clarity: good to excellent

Short range: 2-8 meters

Water clarity: poor to fair

Medium range: 8-15 meters

Water clarity: fair to good

Laser 3D

Schilling UHD ROV

Laser 3D

Target – Hot Stab Panel

Static Scan – Real Time Viewing of 3D Data using 3D at Depth’s Mesh Software

Laser 3D

• Data is processed and

displayed in less than

1 minute

• Range is mapped to

colour

• Rotation of the data to

top view clearly shows

the curvature of the

tank wall

Laser 3D

Jumper and PLETS are the Scan Targets.

Jumper installation was the primary

objective.

• Maximum range measured was 14

meters – not max gain setting

• Performed successful scans of

targets the ROV camera could not

see – good but not perfect water

clarity

Laser 3D

Data Collected

• The INSCAN was able to perform scans

while mounted on the back of the ROV.

• The ROV was stationary

• The resulting scans provided enough

geometric definition to register together

• 3D modelling of major PLET

components was performed using Leica

Cyclone

Laser 3D

Scans Registered Together

• Coincident points were constructed in

both scans

• The models were then registered together

using coincident points derived from the

model – not best practice
