Skandi Neptune is an Offshore Construction Vessel that was operated by Subsea 7 from 2005 until the charter was ended in 2015.


The Skandi Neptune was built in 2001 as a cable layer. In 2005, she was converted to a multi-purpose offshore support vessel and began a long term charter to Subsea 7.[7][8]

In 2010, Skandi Neptune provided ROV capability during the oil spill following an explosion on the Deepwater Horizon in the Gulf of Mexico.[9]


Skandi Neptune has two stern azimuth thrusters, a retractable forward azimuth thruster and two bow tunnel thrusters. Combined with a class 2 DGPS system, these provide excellent manoeuvring capabilities.[7]

She has accommodation for 106 persons in single and double cabins. The helideck is rated for Super Puma L2s.[7]

The stern A-Frame is rated at 60 tonne SWL, the deck crane at 250 tonne SWL. The moon pool and 130 tonne traction winch allow the installation of flexible pipe.[7]


Skandi Neptune can operate as a pipe-laying ship and provides ROV support.
