Progress Report #21 | July 2023
Haul out for warranty works 13-18th July
Whilst Arionas was sitting in her berth, small sea water seepage was noticed from the stern tubes on port and starboard side into the bilges. The leaks were originating from the structural chock fast that was used to secure the new stern tubes in place for the propeller shafts.
Arionas was hauled out between the 13th and 18th of July to complete the repairs under warranty.
No further leaks have been witnessed now Arionas is back in the water or during her sea trial.
STABILITY
Following the approval of the short time stability proposal, the 30 tonnes of additional lead ballast was installed by a team of day workers. The lead plan was supplied by Amico shipyards naval architects.
The process was followed by RINA to ensure none of the bilge pumping equipment or sensors were obstructed. A structural survey was also completed by Amico and approved by RINA before the embarkation.
On the 31st of July, after the installation was completed, the inclining test was completed. The new stability booklet has now been issued and is currently being reviewed by RINA for approval.
E Motion commissioning
E motion commissioning has been underway for dock trials up to the stage of sea trials with the help of Emotions technicians and their subcontractors.
Dock trials took longer than expected to be able to have the system stable prior to moving onto sea trials.
During sea trials the problems continued as one of the two port side propulsion motors suddenly overheated and set on fire. Luckily, the crew’s safety preparation and training become apparent as the fire was quickly extinguished before spreading.
Repair procedures, onboard testing and repair planning is under discussion between the owner's team and Emotion. All testing and inspections are being overseen by the owner's team to ensure the root cause of the fault is understood by all before further testing continues.
Since the incident with Arionas safely back in port, Emotion continue to struggle to have the power management system stable in automatic mode.
Bringing Arionas into RINA classification
With the RINA local surveyor now able to witness the safety systems up and running with Arionas on the dock, multiple visits have been completed that are necessary to bring Arionas into RINA class.
Aswell as testing the onboard systems, there have been additional safety systems that have had to be installed to bring Arionas up to RINA standards, the main items are as below.
•remote starting for the emergency pumps,
•Remote shut down for the galley electrical power
•Additional ventilation shut down on the engine room
•Sprinkler service re commissioning back to operational standard
•Upgrading the connections on the fire hydrants
•Automatic door closing in the galley.
Outstanding items with RINA are now only the approval of the stability booklet that is underway, sea trial once E motion can prove the system as stable and some minor final items that can be closed on the next visit.
