ERRV Esvagt Corona deliveredVessel & ROV News // October 1, 2004
Esvagt Corona was due to start work in the North Sea in late September, followed a month later by a sister vessel, Esvagt Capella.
Designed and built to work worldwide and in all sectors of the North Sea, Esvagt Corona and Esvagt Capella are unique in Esvagt's experience and very innovative as ERRVs or 'safety standby vessels' in as much as they are diesel electric ships.
Designed by Esvagt in co-operation with Zamakona Shipyard, and with Ole Steen Knudsen acting as consultant, they are intended to have an operating life of 20 years or more.
At 44.03m overall, Esvagt Corona and her sistership are propelled by a pair of electrically-driven 175kW HRP 5000 L drive azimuthing thrusters, each with four 1,650mm diameter NiAL bronze blades.
Depending on operating mode and tasks, the ship will be manned with 6-12 man crew - all accommodated in single cabins with own bath and toilet. The rescue zone midship is designed and calculated in such a way that it will fulfill all the different requirements for standby ships in the Danish, Norwegian and UK sectors of the North Sea.
The ship's Fast Rescue Craft (FRC) are of two different types - one being Esvagt's own design, the well-tested ESVAGT Rescue FRC 15 B, with two specially designed outboard diesel engines, and the other one being a Norsafe Mako 655, driven by waterjets, and specifically tested in this role by Esvagt.
