材料:MV Magellan was inbound from Rotterdam to berth 207 at Southampton Container Terminal.At 0530 the pilot boarded the ship at the Nab Tower pilot station.The pilots and the masters passage plans were exchanged and the ships pilot card was given to the pilot.The passage continued along the East Solent,during which time there were various VHF radio conversations between vessels and Southampton VTS,about restricted visibility.The VTS officer gave the pilot a countdown from 5 to 2 cables to the Gurnard buoy.This was given so that the pilot could judge the timing of the wheel-over manoeuvre for the 141° turn into the narrow Thorn Channel.The wheel-over occurred at about 0652 and the ship began to turn.At this time,the W Bramble and NE Gurnard buoys,which are at the entrance to Thorn Channel,could not be seen because of restricted visibility.Various helm and engine movements were made during the turn.However,when W Bramble and NE Gurnard buoys appeared,the pilot realized that the ship was in the wrong position for the heading she was on.Despite further helm and engine orders,the vessel grounded soon after,at 0700.It was not until about 0710 that the escort harbor launch informed VTS of the grounding.With the assistance of two tugs,the ship was refloated near the time of high water,and she safely berthed at 1232.问题:MV Magellan applied wheel at ________ to turn into the narrow Thorn Channel.A.0530B.0652C.0700D.0710The important navigational mark or marks at the entrance to the Thorn Channel is(are)________.A.Southampton Container TerminalB.the East SolentC.the Nab TowerD.the W Bramble and NE Gurnard buoysThe suggestion of a countdown from 5 to 2 cables to the Gurnard buoy is ________.A.for the pilot to judge easily when the wheel should be used to make the turn into the narrow Thorn ChannelB.to remind the pilot that the depth around there is not sufficient for MV MagellanC.to inform the pilot that the visibility around the buoy is reduced furtherD.to request the pilot that further consideration should be given to the wheel-over manoeuvre for the 141° turnIt can be concluded that the cause of the grounding was that ________.A.the Bramble and NE Gurnard buoys were disappearedB.the VHF radio conversations between vessels and Southampton VTS,about restricted visibility,were insufficient and improperC.Thorn Channel was too narrowD.there was an error of judgment by the pilot during the execution of the turn into Thorn Channel请帮忙给出每个问题的正确答案和分析,谢谢!
