Product Description

ABS Grade E NV-F36 Marine Corrosion-Resistant Heavy Plate

Engineered for Critical Zones of Offshore Jacket Legs in Sour Service Environments

 

Product Overview

ABS E NV-F36 is a low-temperature, sour-service resistant steel plate certified by the American Bureau of Shipping (ABS) for offshore structural applications. With enhanced fracture toughness and hydrogen-induced cracking (HIC) immunity, it delivers unparalleled reliability for jacket leg joints subjected to North Sea-level wave dynamics and H2S-contaminated seabed conditions.

 

Certifications & Standards

• Primary Certification: ABS Rule 2F / EN 10225-4

• Supplemental Approvals:
   NACE MR0175/ISO 15156 (Sour Service)  DNV-OS-C101  API 2W Gr.50

• Special Testing:
  SSC Testing per NACE TM0177 Method A (Solution A)

Core Advantages for Jacket Legs

1. Extreme Environment Resilience

• Sour Gas Immunity: HIC-free performance in H2S partial pressures >0.3 psi (NACE Level III).

• Arctic Toughness: Maintains ductility down to -60ºC (Svalbard/Barents Sea proven).

2. Structural Integrity Assurance

• Fatigue Resistance: Exceeds 2×10000 cycles at 100 MPa stress range (DNV-C203 Curve D).

• Lamellar Tearing Prevention: Z35 through-thickness Ψ ≥ 35% at node intersections.

3. Corrosion Defense System

• Seawater Corrosion Rate: 0.02 mm/year (vs. 0.15 mm for standard carbon steel).

• Integrated Protection: Compatible with aluminum-zinc-indium bracelet anodes.
