London Club Warns of Over-Reliance on GPS
Tuesday, October 05, 2010
The London P&I Club said a recent casualty involving a containership serves as a timely reminder of the consequences of failing to check navigation charts for information about corrections that need to be applied to satellite-derived positions.
In the latest issue of its StopLoss Bulletin, the Club refers to an incident in which a containership grounded as a result of total reliance on GPS, coupled with a failure to recognise that a significant correction had to be applied to GPS positions before they were plotted on the chart. During a coastal passage, the ship ran aground after a navigating officer commenced a significant alteration of course about half a mile before he reached the intended alter-course position.
Investigations suggested that the officer was using no means other than GPS to navigate and, even though the ship was on a regular schedule, he was wholly unaware that a significant correction had to be applied before GPS positions could be plotted onto many of the charts used in the service. The Club says a more detailed passage plan would have alerted the inexperienced officer to the danger and required him to cross-check his position by more than one method.
The Club emphasises that seafarers must be aware that, on many charts still in use, a correction has to be applied to satellite-derived positions before the position is plotted on the chart. It adds that navigating officers should always check the charts for information about corrections that need to be applied to satellite-derived positions when preparing a passage plan and alert the navigators to any existing corrections which are required before positions are plotted on the individual charts.

London Club Memperingatkan Ketergantungan Terhadap GPS
Selasa, 5 Oktober 2010
The London P&I Club said a recent casualty involving a containership serves as a timely reminder of the consequences of failing to check navigation charts for information about corrections that need to be applied to satellite-derived positions. P & I Club London mengatakan korban baru-baru ini yang melibatkan sebuah containership berfungsi sebagai pengingat tepat waktu konsekuensi dari kegagalan untuk memeriksa grafik navigasi untuk informasi tentang koreksi yang perlu diterapkan untuk posisi satelit yang diturunkan.
In the latest issue of its StopLoss Bulletin, the Club refers to an incident in which a containership grounded as a result of total reliance on GPS, coupled with a failure to recognise that a significant correction had to be applied to GPS positions before they were plotted on the chart. Dalam edisi terbaru yang loss Buletin, Club mengacu pada kejadian di mana suatu containership didasarkan sebagai akibat dari ketergantungan total pada GPS, ditambah dengan kegagalan untuk mengakui bahwa koreksi yang signifikan harus diterapkan untuk posisi GPS sebelum mereka diplot pada tabel. During a coastal passage, the ship ran aground after a navigating officer commenced a significant alteration of course about half a mile before he reached the intended alter-course position. Selama bagian pantai, kapal kandas setelah petugas navigasi memulai perubahan signifikan tentu saja sekitar setengah mil sebelum ia mencapai posisi mengubah-program dimaksud.
Investigations suggested that the officer was using no means other than GPS to navigate and, even though the ship was on a regular schedule, he was wholly unaware that a significant correction had to be applied before GPS positions could be plotted onto many of the charts used in the service. Penyelidikan menunjukkan bahwa petugas itu tidak menggunakan cara selain GPS untuk navigasi dan, meskipun kapal itu dalam jadwal yang teratur, ia sepenuhnya menyadari bahwa koreksi yang signifikan harus diterapkan sebelum posisi GPS dapat banyak diplot ke grafik yang digunakan pada layanan tersebut. The Club says a more detailed passage plan would have alerted the inexperienced officer to the danger and required him to cross-check his position by more than one method. Club mengatakan rencana bagian yang lebih rinci akan memberitahu petugas berpengalaman untuk bahaya dan mengharuskan dia untuk cross-check posisinya oleh lebih dari satu metode.
The Club emphasises that seafarers must be aware that, on many charts still in use, a correction has to be applied to satellite-derived positions before the position is plotted on the chart. Club menekankan bahwa para pelaut harus sadar bahwa, pada grafik masih banyak digunakan, koreksi harus diterapkan untuk posisi satelit yang diturunkan sebelum posisi diplot pada tabel. It adds that navigating officers should always check the charts for information about corrections that need to be applied to satellite-derived positions when preparing a passage plan and alert the navigators to any existing corrections which are required before positions are plotted on the individual charts. Ia menambahkan bahwa petugas navigasi harus selalu memeriksa grafik untuk informasi tentang koreksi yang perlu diterapkan untuk posisi satelit yang diturunkan ketika mempersiapkan rencana bagian dan memperingatkan navigator untuk setiap koreksi yang ada yang diperlukan sebelum posisi diplot pada grafik individu.
