NKT completes Baltic Cable repair
has successfully completed a turnkey offshore repair for the Baltic
Sweden and Germany. The 250km cable was damaged due to a ship anchor in
the last days of April. NKT delivered the repair project in only 29 days.
NKT subcontracted a vessel provided by JD Contractor for localization of
the fault, de-burial and cut and seal operation onboard. The fault was
detected ~20km outside the Swedish coast at a depth of 30 metres. The final
execution was carried out by cable laying vessel NKT Victoria.
Axel Barnekow Widmark,
Executive Vice President and Head of Service at NKT, said, ‘Time and
accuracy are crucial for the success of power cable service operations
and here we clearly demonstrated that we are quick and efficient when mobilizing
our equipment and skilled repair team even under the current circumstances
‘The operations also showed the importance of having a pre-negotiated
repair contract and a sufficient and updated stock of spare cable parts
in place to ensure quick mobilization and execution'.
The 600 MW
was manufactured by ABB. The cable laying in the river Trave was completed
during Summer 1993, whereas cable laying in the Baltic Sea was completed
in Summer 1994, by the vessel Skagerrak.
HVDC cable has
suffered damages on various occasions in 1999, 2002, 2009, 2011, 2012,
and 2013. In 1999, it was damaged 145 km south of the Swedish coast, south-east
of the Danish island Falster due to a hurricane that passed south of Sweden
and the Baltic Sea.
