| باتوجه‌به افزایش آبزی‌پروری دریایی، طراحی سازه‌‌هایی ایمن و کارآمد برای این منظور حائز اهمیت است. سکو مثلثی[1]در سکوهای شناور پرورش ماهی کشتی مانند[2]، با قرارگرفتن در نقطه برخورد موج با قفس، سبب شکست موج و کاهش انرژی آن، در نتیجه کاهش شتاب‌های عمودی و کاهش نیروی کشش خطوط مهار شده و محیط ایمن‌تری نسبت به قفس‌های پلی‌اتیلن با چگالی بالا ایجاد می‌کند. در این پژوهش با استفاده از نرم‌افزار ارکافلکس[3] دینامیک یک نمونه از این قفس‌ها با سیستم تک مهاره در شرایط آب‌های دریایی نزدیک به بندر چابهار مطالعه شده است. مدل عددی ابتدا با نتایج تجربی صحت سنجی شده است. نتایج نشان می‌دهد، شتاب‌های قائم سکوی اصلی به طور قابل‌توجهی کمتر از سکوی مثلثی واقع در جلوی قفس است. افزایش تعداد سکوهای مربعی شناور، شتاب عمودی سکوها را کاهش می‌دهد. بیشینه شتاب قائم وارده به سکو برای امواج محلی چابهار در صورت استفاده از یک سکوی مربعی |
