Kelautan & Lepas Pantai

Dalam konteks rem industri, Marine & Offshore menggambarkan lingkungan aplikasi yang ditandai oleh serangan korosi yang ekstrem dan persisten, kelembapan tinggi, paparan langsung terhadap air asin, fluktuasi suhu yang luas, dan sering kali adanya atmosfer berbahaya atau mudah meledak. Rem yang ditetapkan untuk tugas Marine & Offshore bukan rem standar; ia adalah peralatan sangat khusus di mana keandalan jangka panjang dan keselamatan dalam kondisi ini adalah pendorong desain utama.

Kebutuhan rekayasa utama dan fitur yang diperlukan agar rem dapat disertifikasi untuk penggunaan Marine & Offshore:

1. Ketahanan Korosi Ekstrem: Ini adalah persyaratan yang paling mendasar. Hal ini dicapai melalui strategi pertahanan bertingkat:
   • Material Selection: Extensive use of corrosion-resistant materials such as stainless steel for all critical components, including pins, fasteners, linkages, and pistons. Bronze is also used for certain components.
   • Advanced Coatings: Application of specialized, multi-layer marine-grade paint systems (often epoxy-based and certified to standards like ISO 12944 C5-M) to all cast and fabricated steel parts. This provides a durable barrier against saltwater and atmospheric corrosion.
   • Component Plating: Critical internal and external components are often specially plated (e.g., with zinc-nickel alloys or chrome) for an additional layer of protection.
2. High Ingress Protection (IP Rating): The brake’s electrical and mechanical components must be completely sealed against the ingress of water and dust. This is designated by a high IP rating, typically IP66 or IP67. The enclosure for the electromagnetic coil, thruster, or terminal box is designed to be completely watertight, even against powerful jets of water or temporary submersion.
3. Explosion-Proof Certification: Many offshore applications, particularly on oil rigs, FPSOs (Floating Production Storage and Offloading units), and tankers, are classified as hazardous locations due to the presence of flammable gases. In these cases, the brake must also be certified as Explosion-Proof according to international standards like ATEX dan IECEx.
4. Third-Party Marine Certification: For critical systems, the brake and its performance must be approved by a recognized marine classification society. This involves a rigorous design review, material traceability, and witnessed testing to the standards of bodies like DNV (Det Norske Veritas), ABS (American Bureau of Shipping)atau Lloyd’s Register. This is the ultimate proof of the brake’s suitability for the application.

Rem/ rem yang ini penting untuk operasi yang aman dari berbagai peralatan di sektor ini, termasuk anchor handling winch, mooring winch, crane offshore, drawworks, tensioner pipa dan kabel, serta davit. Kegagalan di lingkungan ini bukan pilihan, jadi setiap komponen dirancang dengan faktor keselamatan dan daya tahan tertinggi.
