The Katja was an oil tanker owned by the Finnish shipping company Lundqvist Rederierna from Mariehamn on Åland . From 2013 to 2015 the oil tanker sailed as Kamila under the flag of St. Kitts and Nevis . The ship has since been sold and renamed the Bonita Queen .
In 1997 the tanker lost 167 tonnes of heavy fuel oil of the Bunker-C type after being damaged in an unsuccessful berthing maneuver in the port of Le Havre . On the night of August 14, 2012, the ship ran aground with 87,000 tons of heavy fuel oil on board off the bird protection island Minsener Oog in the Lower Saxony Wadden Sea National Park , but was towed free again.
The ship
The 232 meter long ship was built in 1995 at Sumitomo Heavy Industries' Oppama shipyard in Yokosuka , Japan . The keel laying took place on January 12 and was completed on August 1, 1995. The surveyed with 52 067 GT Katja is an Aframax - double hull tanker and was registered in the Bahamas.
The ship is powered by a Sulzer two- stroke diesel engine of the type 6RTA62, which acts on a propeller. Three generators and an emergency generator are available for the power supply .
Incidents
1997 oil spill
Two years after the tanker was put into service, an accident occurred on August 7, 1997 at 12:20 p.m. CEST . During the mooring maneuver of the Katja , which had loaded 80,000 tons of oil, a bunker tank was damaged and leaked at quay 3 of the port of Le Havre. There was an oil leak, 187 tons of the heavy oil Bunker-C, which was used as fuel, ran into port basin 3. The accident happened shortly before the low water. Almost half of the oil leaked into other docks with the ebb tide and contaminated a number of port facilities. An estimated 30 to 60 tons of oil leaked from the harbor basin into the open sea as the tide ran down . Local authorities, fire brigades and the French army fought the oil spill on the coasts of Le Havre and Saint Adresse with 300 men.
According to the specifications for double hull tankers, it was not mandatory to equip the damaged tank with a double side wall.
Ground contact 2012
In August the ship was on its way from England to Wilhelmshaven with 87,000 tons of oil on board . On the night of Tuesday, August 14, 2012 at around 1 a.m. CEST, the oil tanker ran aground near the island of Minsener Oog . The ship had got stuck with a list of 1.5 °.
On site were initially the assistant tugs Bugsier 1 , Bugsier 3 , Bugsier 4 and Bugsier 6 of the Bugsier-, Reederei- und Bergungsgesellschaft , the Ems , Elbe , Wilhelmshaven and Blexen of the Unterweser shipping company as well as the multi-purpose ships Mellum of the water and shipping authorities Wilhelmshaven and Neuwerk of the Cuxhaven Waterways and Shipping Authority and the Nordic salvage tug . An oil spill ship was also on site. Wind force 4 from the north-northeast prevailed during the recovery. The Cuxhaven accident command coordinated the action.
After five hours, the Katja was towed free at around 6:15 a.m. the next morning when the water level rose with the help of the Nordic and four of the assistant tugs that acted as pressure tugs and continued its journey to Wilhelmshaven.
The Lower Saxony water police started investigating the cause of the accident after the ship was moored in Wilhelmshaven. A navigation error was later given as the cause of the accident. The classification society Det Norske Veritas required the ship to visit a shipyard within four weeks to repair light damage to the ground and not to take over any cargo beforehand.
After the deletion at the north-west oil pipeline in Wilhelmshaven, the ship initially anchored in the deep-water roadstead in the German Bight. At the beginning of the 35th calendar week it was docked for repairs at Blohm + Voss in Hamburg , where it was repaired until September 13th.
The WWF warned of the dangers of shipping in the Wadden Sea in connection with the ship getting stuck . It was a serious situation and the towing maneuver could have gone wrong under different weather conditions, said a spokesman.
