Metode Buhlmann digunakan dalam penelitian ini untuk menghitung premi asuransi marine cargo dengan objek penelitian PT Tugu Pratama Indonesia. Proses perhitungan dilakukan dengan memprediksi ekspektasi aggregate loss dimasa yang akan datang dengan melibatkan pengalaman klaim masa lalu sebagai dasar perhitungan. Perhitungan aggregate loss dilakukan untuk tiap grup risiko, yakni grup oil, grup export import material, grup inter island material, dan grup gas and lubricant. Hasil ekpektasi aggregate loss akan digunakan untuk menghitung premi murni yang dikenakan kepada tertanggung tiap jenis risiko. Premi murni yang dihasilkan akan dibandingkan dengan premi aktual perusahaan yang digunakan perusahaan.Hasil penelitian menunjukkan bahwa premi murni untuk grup risiko oil adalah sebesar 0,098%, grup risiko export import material 0,107%, grup inter island material 0,078% dan grup gas and lubricant 0,339%. Setelah dibandingkan dengan premi aktual perusahaan, premi grup oil, grup export import material, dan grup inter island material mempunyai nilai lebih tinggi dibandingkan premi Buhlmann. Sehingga, terdapat ruang bagi perusahaan untuk menurunkan premi sampai batas premi kredibilitas Buhlmann. Sedangkan, premi grup risiko gas & lubricant mempunyai nilai di bawah premi Buhlmann. Sehingga, perusahaan dapat menaikkan premi untuk mengurangi risiko kerugian dimasa mendatang.
