Cathodic Protection Surveys typically involve equipment such as reference electrodes (Ag/AgCl or Cu/CuSO4), current interrupters, and data loggers. Size varies based on application, with portable units being common. Materials include stainless steel, copper, and plastics for corrosion resistance.
Marine Underwater Services often utilize ROVs (Remotely Operated Vehicles) with sizes ranging from small (0.5m x 0.3m) to large (3m x 2m). Buoyancy is adjusted using syntactic foam or compressed air systems. Materials include high-grade aluminum, titanium, and corrosion-resistant polymers.
Viscosity considerations apply to underwater coatings and lubricants, typically ranging from 50-5000 cP depending on application. Grade specifications depend on service conditions, such as ASTM A123 for galvanizing or NACE standards for corrosion protection.
Buoyancy aids in underwater operations may include foam blocks or inflatable systems with buoyancy ratings from 50kg to several tons. Materials used are closed-cell foams, polyethylene, or composite materials for durability.
