Introduction
• DataCo is a new PNG SOE established in 2014 – Is building the PNG National Transmission Network (NTN)– Will be responsible for National and International submarine cables
and international gateways.– The NTN will use part of the PNG LNG fibre cable
• The PNG LNG fibre cable project– Completed in 2014– Serves a major new PNG oil and gas project– Example of Government and private enterprise working together to
provide much needed fibre infrastructure for public communications.• Use of fibre technology to offshore and on shore serve oil and gas installations• Provides new fibre capacity to parts of PNG that would otherwise not be able
to economically justify the investment• DataCo is now commercialising some of the fibres

Submarine Cables in PNG
• International Submarine cables
– Existing cables - APNG-2 and PPC-1
– Planned new cable from Port Moresby - A number of options being considered
• National Submarine Cable Project
– Planned new 5,500km domestic submarine cable network connecting 14 coastal centres and major islands in PNG
– At the vendor evaluation stage

• Currently, data transmission on
an deep water offshore
platform far from the shore is
limited and constrained by its
satellite connection to well
below 10 Mb/s
• Platforms already connected
with optical fibre technology
benefit from much higher
capacity (~1Gb/s installed
capacity) and experience much
higher traffic (75 – 150 Mb/s)
• Data transmission for
operations will jump in future
platforms connected with
optical fibre given the
increased weight of remote
control and new operations
needs such as Permanent
Reservoir Monitoring

PNG LNG Submarine CableConnecting remote production platform to onshore facilities
• Fibre connection to a fixed offshore platform (KumulMarine Terminal) through a J-tube
• Provides communication from the platform and associated equipment to Port Moresby
• Additional BU’s provided for future use for National Submarine Fibre Cable connection to: – Daru, – Kerrima– Bereima

Summary
• Only fibre can provides cost effective and reliable communications solutions for the long term communication needs of off shore oil and gas operator for. – Crew welfare
– Safety
– Platform management and
– operations functions in
• Fibre solutions are more expensive that alternatives such as satellites so have a number of economic and technical issues that need to be resolved.
• The PNG LNG fibre project is a good example of where the economic and technical problems were successfully solved.– The project was technically difficult because of the remote location and difficult route e.g. the
fibre cable was required to be buried over a long length of the submarine route in the delta of the Fly River.
– The project structure is an example of successful Government and the oil/gas companies cooperating to share costs to enable the superior fibre solutions for the oil and gas project operator as well as to provide much needed communications capacity in remote areas of PNG which would other wise not be viable for fibre communications.
