In week eleven, the first tests on the sea were carried out, i.e. tests of the vessel in the North Sea with the representation of The Danish Maritime Authority on board as well as workmen, etc.

The first trial trips went off extremely well, and only a few problems occurred. We have carried out a series of tests in cooperation with The Danish Maritime Authority and a number of tests of the vessel’s properties - among others, load test of one hour’s navigation with 100 per cent load, chrash test, rotary test and instrument test. It was a great experience to navigate her out through the lock the first time. Due to insurance matters I was not allowed to navigate her in and out of the lock myself. Therefore an extremely experienced shipmaster was hired, and he did the job very well. However, I was allowed to navigate her out of the port and to do the tests on the sea. The vessel appears suitably lazy on the sea, and I think it is a comfortable vessel to work at.  The money spent on insulation to reduce noise nuisances seems to be a most excellent choise. There was an extremely low noise level on the vessel. You had to listen very carefully to hear if the engines were working, when you were staying in the mess, even though they worked with a 100 per cent load. The maximum speed is approximately 11.5 kn. The fuel supply at moderate speed (approx. 9 knot) is 70-90 l/h, but the vessel may use more fuel when it becomes more equipped and a bit heavier. We experienced a few hydraulic leakages from one of the steering gears and some insulation material in the engine room was not properly fastened. Moreover, there was a few problems with the pressure of the cooling water and a few other small defects. Most of them were remedied on the sea.
So it looks very promising for the future./Torben


11 March 2014

  • On the way out of the lock at Hvide Sande.
  • Rotary test on a calm North Sea.
  • The anchor also worked fine.

  • On the way back to the port after the trial trip.

  • At quay by the shipyard in Hvide Sande. Now the vessel needs to be painted, and a few defects need to bee fixed.

Status:

The construction of Aurora is in progress just as planned. The violent storms have not had any consequences for the construction of the vessel. It has been lying behind the lock in Hvide Sande at Jutland’s west coast, but however it has been secured with extra bow line. A series of great circumstances such as good planning, excellent craftsmanship combined with successful weather in general has meant that the work has been carried out satisfactorily and the schedule has been followed. Only few problems have occurred. There is no doubt that the experiences among the crew at the yard are of great importance. Several employees have practical sailing experience from the fishing and merchant navy which implies that great practical solutions are incorporated in the vessel. 

The employees work in many different sections of the vessel at the same time. The accommodation area begins to take shape, almost all berths are in place and cupboards and closets are currently being installed. The work in the wheelhouse is also far in progress. The ceiling and walls are finished, and we are working to make a cover for the windows and to finish the control desks.  

In the engine room the piping system and the large exhausts are about to be in place. Now the work of making the deck (floor) in the engine room has just begun. Gradually, as the piping systems are finish, they are being tested, but they cannot be subject to a final test, before they are completely finished. There are many systems that should function: pressurised air, vacuum air, bilge drainage (three systems), fire extinguishing systems (three systems), ballast system with five tanks, freshwater system with watermaker, water purification, double waterworks and three tanks, wastewater accumulation with pumps and three tanks, fuel system with five tanks, offline fuel purification, transfer pumps, hydraulics system with crane, CTD boom, four winches, A-frame, salt water system for laboratories, cooling systems for engines, gear, hydraulics, ventilation systems, etc., heating with engine heat, oil-fired boiler and heat pump, etc.

We are currently planning the many tests which will be made, partly to reveal errors (very few, hopefully), and partly to document that the systems function as expected. The first tests are called HAP (Harbour Acceptance Tests) and as the name suggests these tests must be performed while the vessel is at quay. Later, ‘seatrials’ will take place at sea. In addition, training exercises, demonstrations and tests of the vessel’s safety equipment and fire extinguishing equipment should be made to obtain an approval by The Danish Maritime Authority and subsequent commissioning of the vessel.   It will be interesting to see which problems and challenges we get when the whole vessel is being tested and all machinery is ready to operate. 

The construction work is followed closely by the project group and the counsellors, and the Skipper Torben Vang stays at the yard in Hvide Sande three-four days a week to follow the construction process thouroughly.

The project group also works to obtain an improved operation of the vessel. The project group has held a meeting with Aarhus Harbour, and now the vessel has achieved a berth close to Aarhus Stream’s outlet to the sea which appears to be an excellent place. In addition, the project group makes agreements on the access to a small storage area at the harbour and other practical details.

The summer and autumn 2014 will probably be an extremely active period with many exciting expeditions with the vessel. An operation group has been set up to handle the vessels’ operation and economy, and there is already a great demand for ‘vessel time’. This year will be marked by great earnings, and generally it seems that the vessel gets a really good start in its work for Aarhus University and the sea research in Denmark.

12 August 2013

  • AURORA on its way to Hvide Sande, towed by the tug boat, DANASUND. At present, it is laying by Helsingør and is expected to reach Hvide Sande on thursday or friday, depending on the weather.

 

10 August 2013

  • The tug boat, DANASUND, has come to get AURORA, and they are now heading towards Denmark. Detachable lights have been mounted for use in the night, and the tanks are filled with ballast water to make the vessel completely stable when it is towed. On the photos, the vessel draws 2.4 metres! (Click on the pictures to see them in full size).

     

 

7 August 2013

  • The big day arrives when AURORA is lifted out from the shipyard and is launched for the fist time. This is done by the shipyard's big crane. The vessel is still without accomodation, engines and equipment. The zinc anodes which should protect the vessel against corrosion, are clearly seen under the water line. (Click on the pictures to see them in full size).

         

 

9 July 2013

  • The shipyard in Poland has soon finished the steel work. Roughly speaking, the work is divided into three phases: phase number one is includes prospecting, planning, approvals (shipowner, authorities, etc.), phase number two includes building of the hull (steel work) and the last phase includes equipping. This means that the vessel is 2/3 finished by now. When it is painted, it will be towed to Hvide sande. Here, the vessel's four engines will be mounted together with the entire accomodation. The electrical equipment, heat and cooling systems, pantry, insturments, scientific equipment should also be installed there.

  • The construction of the vessel has been observed closely, partly by use of shipbuilding experts and partly through own inspections. The AU has inspected the shipyard at least once a month. Many small things have been corrected during the phase, and lots of decisions have been taken at the shipyard in Poland. It is also nice to observe that plenty of safety equipment has been used during the building, e.g. helmets, ear protectors, shielding, racks, ect. The ship group consisting of Peter Grønkjær, Hans Røy, Henrik Fossing, Per Trinhammer and Torben Vang, are all researchers from the AU and used to the sea. And they are all secure about the fact that the hull has been built in Poland.
