Global Marine Systems Limited completed the installation of the most northerly subsea cable system in the world, connecting the research community in Ny-Ålesund, Svalbard, Norway. The 500km cable system was installed in October 2014 using the vessel Cable Innovator and its Hi-Plough equipment. The installation provided redundancy to the network and was completed despite challenging Arctic conditions including freezing winds, snow, icebergs and temperatures down to -10°C.

Case Study - Aberdeen Harbour use Siklu EtherHaul to Integrate CCTV & Access ...Purdicom
As one of the UKs busiest ports and serving the North Sea oil and gas industry, Aberdeen Harbour uses Siklu EtherHaul millimetre wave wireless to connect the new Torry Marine Base with a future-proof solution.
Nexans 33kv cables for onshore windfarm projects are now available with a conductive outer skin on the protective sheath, this innovative feature assists the installer in testing for sheath damage.
This conductive outer skin feature represents one of Nexans "Windfarm Innovations Program" which covers a range of features for cables and associated services which can improve the overall efficiency of an onshore windfarm installation through reducing installation time and overall costs.
The cables used to convey power between the wind turbines and the collector substations are laid directly in trenches which can often cross challenging terrain. A common problem on sites is that the cable sheaths are damaged by stones or other obstacles during laying but this damage is not discovered until the cable is buried and testing is being carried out.
On standard cables, in order to make a "sheath test" (which measures the resistance between the cables metallic screen and the outer sheath layer), the outer sheath needs to be in contact with moist soil/sand to provide a return electrode for the test. This means the test can only be performed satisfactorily once the cable is buried in the ground.
By supplying cables which have a very thin skin of conductive material, testing can be done without the need for the cables to be buried. An initial test can be made whilst the cable is still on the drum to establish whether the cable sheath is intact before beginning to lay it in the ground, the test can then be repeated as soon as the cable is laid in its’ final position before the cables are blinded with soil or sand.
Any damage to the sheath can found from the test and repaired without the expense and lost time of having to excavate the surrounding soil /sand. A further feature is to have the sheath in a natural colour with the conductive skin as black. This assists in the identification of any sheath damage as the natural colour of the sheath is visible through the black layer at the site of damage.
The semiconductive layer is also a perfect way to detect sheath errors of cables installed in ducts. Even if the duct is dry during installation; this may change during its’ lifetime. Once water has entered a duct it normally stays there and may damage a cable with an existing sheath error in this area. With a conductive layer the cables can be tested before and after installation into ducts to be sure no sheath error is present which could reduce the cables’ lifetime.

CASE STUDY
Vessel: Cable Innovator
Length: 500km
Location: Arctic Ocean
Subsea Equipment: Hi-Plough
Vessel: Cable Innovator
Services ProvidedGlobal Marine System Limited completed
the installation of the most northerly
subsea cable system in the world, which
will service the research community of
Ny-Ålesund in Svalbard, Norway. The
installation was completed in October 2014.
The research station supports earth and life scientists
and is part of an international research community.
Global Marine had previously been involved with the
installation from Svalbard archipelago to the Norwegian
mainland now extending the system further into the
Arctic Circle. The scope this time was to connect a
research facility in Ny-Ålesund to the main town of
Longyearbyen via two cables providing redundancy to
the network if required.
Global Marine used multi-role DPS-2 Cable Innovator to
install the system and the Hi-Plough to complete subsea
operations.
Global Marine provided an end-to-end solution to the
customer from initial surveys through to the installation
of the fibre optic cable system, which included:
• Desk survey
• Route engineering
• Pre-lay grapnel run and route clearance
• Shore end installation
• Deep water operations
• Post project reporting

The ChallengeAssets
Cable Innovator successfully completed the installation
despite the difficult environmental conditions using its
Hi-Plough burial capability, installing shore ends at both
Ny-Ålesund and Longyearbyen.
Cable Innovator, the purpose built DPS-2 cable ship
was used to install the system, she has a track record
of working in subsea engineering projects around the
globe with experience of both transatlantic installations
as well as operations providing platform to platform fibre
connectivity for the oil & gas market in the North Sea.
Global Marine’s range of Hi-Ploughs meet the demand
for deeper burial, and represent the latest in deep-
water plough technology, operating to a depth of 2,000
metres. Each Hi-Plough has 500kW of jetting power to
reduce the active tow tensions and can be fitted with
either a 2 metre plough share or a 3.25 metre injector
share.
Global Marine installed the subsea cable in some of
the most challenging weather conditions experienced
during an installation; the team were faced with freezing
winds, driving snow and ice bergs not to mention drops
in temperatures to -10°c during the project.
The location of the project presented numerous
hurdles. Lack of satellite coverage due the high latitude
made communications more difficult, limited means
of transport meant logistics of getting people and
equipment to and from the island and between the
landing sites needed to be very well planned, and of
course the impact of the ever changing extreme arctic
climate.
The picture above shows the shore end installation at
Ny-Ålesund.
It has been a pleasure to work with Global Marine
during this project. The installation period on board
Cable Innovator clearly demonstrated to us that we
were working with a very professional, flexible crew on
all levels. I would also like to mention the beach team
who assisted in getting the cables through the HDD
ducts safely.
