Fathom Systems

Integrated Monitoring, Communications and Control Systems for Modern DSV Designs

Subsea Expo 3rd February 2016 Gareth Kerr – Managing Director

Technology changes within the Diving industry...

Many of the diving support vessels currently in service are over 10 years old, with some older than 30 years.

Many of these older DSVs have simple ‘low-tech’ electronic equipment within the diving system due to their age and the lack of suitable technology at the time:

Upgrading older dive systems...

Seven Pelican

Wellservicer

Alliance Orelia

Mermaid Commander

MayoRockwater 1

Seawell

Eagle

Upgrading brought acceptance of new technology...

By upgrading older DSVs with new technology including state of the art Diver Monitoring systems, communications systems and instrumentation brought an acceptance amongst vessel owners and clients and the industry in general.

We installed Diver Monitoring Systems:

Communications Systems:

Instrumentation and Control Systems:

• Gas Analysers• Chamber Climate Controls• Shutdown Systems

The Advantages of Connectivity:

One significant difference between modern and legacy equipment is connectivity. We design and build equipment and systems that allows communication and data transfer between different sub-systems and areas of the dive system.

• Fibre-optic networks for comms & data.

• Redundant Ethernet networks.

• Robust serial data links.

The Advantages of Connectivity:

Interconnected systems can co-operate to make operations safer, maintenance and diagnostics simple and to share important parameters:

• Gas analysers receive chamber and bell depth signals to allow correct management of gas concentrations.

• Digital diver communications over fibre networks allows voice communications throughout the system.

• Remote management and control of instrumentation and sensors saves time and simplifies control rooms.

• Individual Diver exposure data is available throughout the dive system, to SPHLs and to shore.

Challenges for Dive System builders with new DSVs...

• Dive System suppliers do not manufacture all equipment in-house, so they must work with sub-suppliers.

• Managing interfaces with equipment suppliers, vessel owners, certifying authorities and the shipyard is difficult and expensive.

• Many interfaces and multiple equipment suppliers presents a real project risk – cost, schedule and function.

Reducing the Interface Risk...• Reducing the number of sub-suppliers reduces project risk, interface

management effort and cost.

• Choosing sub-suppliers who can offer a complete certified system design rather than simply supplying discrete components places responsibility for system function and compliance with the supplier.

Making the Right Choice...

• Many factors affect selection of equipment sub-suppliers:• Functionality & specification compliance• Cost (Purchase cost & installation cost)• Track-record (reliability, references)• Installation and operational support including warranty• Client / owner preference

• Why Fathom Systems are chosen:• Safety, Reliability and Quality of equipment and systems.• Capability to offer complete integrated certified system designs.• Industry standard Digital Diver Communications Systems with 133

installed systems & 21 SPHL/HRF systems.• Industry Standard Thru’-water comms systems (37 systems installed)• Market leading Diver Monitoring Systems – NORSOK compliant.• Best in class Gas Analysis systems with exceptional reliability.• Unrivalled operational support.• Low cost of ownership.
