Jakob Maersk oil spill

Jakob Maersk General
The Jakob Maersk was a ship registered in Denmark that was owned and operated by A.P. Moller that was working for the the Shell Oil Company at the moment. The ship carried about 88,000 tons of crude oil from Kharg Island in Iran while entering the Port of Leixoes on January 29, 1975 in the Northern part of Portugal to discharge the oil to Sacor Refinery. The ship consisted of 17 crew members that day.

Oil Spill
At about 12:25 P.M. on January 29, 1975, the ship was entering the Port of Leixoes in Portugal, while entering the Danish Tanker hit sandbar and cause the ship to spill massive amounts of oil into the ocean followed by a few explosions inside the engine room. The cause of this infamous disaster was because of human error. 7 of those 17 crew members died in that explosion, the majority of deaths were engineers. During the time of explosions, the ship began to sink causing survivors to jump into the water, a tugboat named Monte de Luz assisted by rescuing survivors that were nearby. The Jakob Maersk oil spill was the second largest spill at the time which occurred in the second largest city in Portugal. Out of the 40,000 to 50,000 tons of oil that were spilled consumed either by the fire or the ocean, 20,000 to 25,000 tons of that oil drifted into the sea and about 15,000 tons came to shore due to the wind direction during the first few days. The explosion caused thick black smoke to rise. The ship burned for 58 continuous hours. There were reports of locals being affected by the fire that was caused but it did not escalate into serious effects or injuries.

Clean Up
The owners of the ship and the Shell company met together to decide how the oil spill was going to be clean or treated. A company called Fina Oil Company was nearby and contributed several drums of Finasol. This oil spill unlike others was very lucky due to the fact that there was an immediate response. There were boats readily available both large and small to use as transportation. Equipment was offered of all types especially heavy equipment that was necessary. Hoses and nozzles were provided by the local fire department. Labor was available from skilled to unskilled which was crucial for this operation.

The nearby Oporto airport made it easier to deliver specialized equipment within a near proximity. Communication was easily established in a nearby communications facility that was used as the Command Center. The type of shoreline made it an easy accessible area with fairly easy mobility of machinery and personnel. The fire that was caused was in some ways fortunate because it burned most of the fuel and if it had not been for it there would have been an even bigger mess on the shoreline. BP made a huge contribution to the oil spill by contributing a chemical dispersant via airplane with 140 drums of BP 1100x on January 30, 1975, 150 of dispersant on January 31, 1975, provided a team of 5 to clean up the spill as much as possible. It was approximated that 2,000 barrels of dispersant was used to treat the oil spill. The purpose was to try and eliminate the oil on the coast using the waves as assistance to spread the dispersant. Even though it was a somewhat effective method is merely masked the oil in the sand. Later on machinery was brought in to dig up the contaminated sand and clean it using another method.

One of the most affected areas were the prow had washed up onto rocks was extremely difficult to clean up because it was not just crude oil that had spread, it was bunker C oil a heavily residual oil. This area was left until late in the clean up and was extremely difficult to clean because the bunker C oil had been spread and untreated for some time. Dispersant was also added and affected very minimally due to the heavily seated bunker C. The clean up was the responsibility of the Portuguese Navy, Commandant Casquinno was appointed to clean up the oil spill and came up with a plan. The plan was separated into two actions, the first part of the plan was to clean up as much oil as possible that was in the water and the second part of the plan was to clean the oil that washed ashore.
