The vessel will be specially designed for diving and subsea operation duties with a high focus on good sea-keeping abilities, excellent station-keeping performances and low fuel consumption.
It will be fitted with an offshore crane weighing more than 200 tonnes, remotely operated vehicle hangar and a twin bell 18-man saturation system, supporting split level diving operations to a maximum diving depth of 300m.
The vessel is scheduled to be delivered from Norway midway through 2016, with the contract leaving the option open for the purchase of another vessel.
Harkand formed earlier this year through the merger of Iremis, Integrated Subsea Services, Andrews Survey and Veolia Marine Services, with the group now enjoying sales in excess of $US400 million ($A449 million).
