A cable protection system (CPS) protects subsea power cables against various factors that could reduce the cable's lifetime, when entering an offshore structure. When a subsea power cable is laid, there is an area where the cable can be subjected to increased dynamic forces the cable is not necessarily designed to withstand over its lifetime. Cable protection systems allow the specification, and thus cost, of a subsea power cable to be reduced by removing the need for additional armoring. Cables can be produced more cheaply, whilst still providing the 20-plus-year lifetime required.

  • اعتمد مطورو مزارع الرياح البحرية على وجه الخصوص استخدام أنظمة حماية الكابلات بسبب المنطقة الديناميكية حيث يأتي الكابل من قاع البحر ويدخل في «عمود أحادي /أنبوب جاي». ويرجع ذلك جزئيًا إلى احتمال حدوث تجوب موضعي (تعرية الرواسب) بالقرب من الهيكل. يتكون نظام حماية الكابلات عمومًا من ثلاثة أقسام، واجهة مُمركز أو واجهة عمود أحادي ونظام حماية للمنطقة الديناميكية ونظام حماية للمنطقة الثابتة.

  • اعتمد مطورو مزارع الرياح البحرية على وجه الخصوص استخدام أنظمة حماية الكابلات بسبب المنطقة الديناميكية حيث يأتي الكابل من قاع البحر ويدخل في «عمود أحادي /أنبوب جاي». ويرجع ذلك جزئيًا إلى احتمال حدوث تجوب موضعي (تعرية الرواسب) بالقرب من الهيكل. يتكون نظام حماية الكابلات عمومًا من ثلاثة أقسام، واجهة مُمركز أو واجهة عمود أحادي ونظام حماية للمنطقة الديناميكية ونظام حماية للمنطقة الثابتة. كان يُنظر إلى تركيب «أنبوب جاي» للأعمدة الأحادية البحرية القابلة للتجديد على أنه نهج مكلف، ونوع حماية «إغلاقي» من نظام حماية الكابلات الذي يخترق الجدار الخارجي للعمود الأحادي، بواسطة فتحة بزاوية مصممة خصيصًا تتيح تبسيط تصميم العمود الأحادي، ويزيل الحاجة إلى أعمال إضافية بعد إزاحة الركام الذي يتضمن عادة استخدام للغواصين. أصبح هذا النهج هو المعيار الصناعي في تصميم العمود الأحادي، مما يساعد المطورين على خفض تكاليف البناء.

  • A cable protection system (CPS) protects subsea power cables against various factors that could reduce the cable's lifetime, when entering an offshore structure. When a subsea power cable is laid, there is an area where the cable can be subjected to increased dynamic forces the cable is not necessarily designed to withstand over its lifetime. Cable protection systems allow the specification, and thus cost, of a subsea power cable to be reduced by removing the need for additional armoring. Cables can be produced more cheaply, whilst still providing the 20-plus-year lifetime required. Offshore windfarm developers have widely adopted cable protection systems due to the dynamic areas where the cable leaves from the seabed and enters the monopile/J-tube, in part due to the potential for localised scouring to occur near the structure. A CPS generally consists of three sections: a Centraliser or Monopile interface, a protection system for the dynamic area, and a protection system for the static area. The installation of J-Tubes for offshore renewable monopiles was viewed as a costly approach, and a 'latching' type of cable protection system which penetrates the outer wall of the monopile, via a specifically designed angled aperture enables the simplification of monopile design, and removes the need for additional works post pile driving which usually involved the use of divers. This approach has become an industry standard in monopile design, assisting developers to reduce their costs for construction. (en)
