Re: [Oil&Gas] PLTU Suralaya Terbakar

 

PLTN belum saatnya di bangung. Kita lihat saja pertamina refinery yang sudah
memiliki segudang certificate internasional dan semua SDM nya memperoleh
pelatihan HSE model akhir yang canggih2.... toh.... pada tahun 2009 dan 2010
terjadi kebakaran kilang Balikpapan, Kilang Cilacap dan depot Pelumpung
tanjung priok. Sekarang PLTU yang terbakar. Kita harus menerima realitas
yang terjadi. SDM kita belum siap dalam HSE. Jangan lagi membuat cerpen.
