00:50 hrs.: In order to lower the stress on the damaged hull side, loading condition with ballast shifting has been calculated and proposed to the vessel and owner. The condition of the vessel has been put under control.

Providing advice in the most critical phase
When a casualty occurs the atmosphere on the vessel might be stressful. It is at this time the professional DNV Emergency Response Service team will gather in the DNV Head office at Høvik, Norway, to do the necessary calculations with regards to the stability and the strength of the vessel. The ERS team will give advice, based on these calculations and the long experience among the team members, on how to react to the incident to ensure a minimization of damage.
Advice will be given to the owner/managers or directly to the Master of the vessel.
Follow up of incidents
After the first critical hours of an incident, when the control is gained of the vessel, the DNV ERS team can calculate new loading conditions and make plans for transferring cargo/ballast in order to save the vessel and the environment from further damage/pollution.
