چکیده: (571 مشاهده)
خطوط مهار، اجزا اصلی در پایداری سازه‌های شناور در دریا هستند. وزنه‌های معلق و بویه‌های مغروق دو دسته از ادوات هستند که برای افزایش تأثیر خطوط مهار طراحی شده‌اند. در این مقاله تأثیر وزنه‌های معلق بر حرکات یک شناور نیمه مغروق با در نظر گرفتن شرایط محیطی خلیج فارس بررسی شده‌است. بدین منظور، نیروی بازگرداننده خطوط مهار در شرایط آب آرام، حرکات سازه شناور و کشش یکی از خطوط مهار آن در موج نامنظم با دوره بازگشت ۱۰۰ ساله بررسی شده است. نتایج نشان می دهد، افزودن وزنه‌های معلق از سویی سبب کاهش حرکات سازه شناور و از سوی دیگر باعث افزایش کشش خطوط مهار خواهد شد. این دو نتیجه متفاوت، نشان می‌دهد که اضافه‌کردن وزنه‌های معلق به خطوط مهار، نیاز به بررسی و تحقیقات بیشتری دارد.
