| 16 Abstract About 2044 c.d.s.t. on July 22, 1980, the upbound Panamanian bulk carrier M/V Seadaniel, with a Crescent River Port Pilot's Association (CRPPA) pilot aboard, collided with the downbound German containership M/V Testbank, also with a CRPPA pilot on board, while meeting in the Mississippi River Gulf Outlet Canal near Shell Beach, Louisiana. The Seadaniel took an unexpected turn to the left due to an erroneous left rudder response to the pilot's right rudder order and struck the Testbank raking down the port side. The damage to the Seadaniel was light and the damage to the Testbank was moderate. There were no deaths or injuries caused by the accident; however, the inhabitants of Shell Beach were temporarily evacuated and the waterway closed for about 3 weeks due to the environmental pollution. The National Transportation Safety Board determines that the probable cause of this accident was the application of left rudder by the helmsman of the Seadaniel when the pilot had ordered right rudder. Contributing to this accident was the failure of the ship's officers on the bridge to take any positive action to correct the helmsman's error and the failure of the pilot and master to more closely observe the helmsman's responses to rudder orders in this close quarters situation. | |||||
