The first offshore vessel with the DNV GL class notation Shore Power has been certified.

The Shore Power notation from DNV GL verifies the design and installation of the K Line Offshore AS owned KL Sandefjord's on-board electrical shore connection.

“We are very pleased to receive this notation for our large and powerful anchor handler KL Sandefjord which reflects our commitment to ensure a cleaner port environment,” said Espen Sørensen, senior vice president, operation and technical at K Line Offshore AS.

“With an on-board shore power installation tested and verified by DNV GL, we now have an offshore vessel equipped for the future."

He added that as result of the good cooperation with the Bergen Port Authority and DNV GL during the notation process, the operator has also decided to apply for the Shore Power class notation for the vessel's sister vessel, KL Saltfjord.

“There is an increasing awareness of the impact of shipping emissions in ports and this is driving investments in cold ironing,” said Jon Rysst, senior vice president and regional manager North Europe, DNV GL. “This is leading to ports both requiring and incentivising the use of alternative maritime power (AMP). As access expands, alongside the rise of fully electric and hybrid vessels, cold ironing could soon become standard procedure in many ports around the world – with a noticeable positive impact on air quality. With the Shore Power notation shipowners can easily document a safe interface between shore facilities and the ship, based on IEC standards."

DNV GL’s electrical shore connection class rules cover safety requirements for a vessel’s on-board electrical shore connection. The Shore Power notation ensures a safe and efficient way of performing the connection and disconnection of shore power. DNV GL also verifies compatibility between ship and port and provides recommendations for a well-defined future proof technical solution.

The technical requirements are based on the international standard for high voltage shore connections established by IEC, ISO and IEEE in IEC/ISO/IEEE Publication ‘80005-1 Utility connections in Port – Part 1: High Voltage Shore Connection (HVSC) Systems’. Part 3 of this standard is currently under development and will deal with low voltage shore connections.
