Oil and gas fields are mainly located beneath inland waters in offshore areas around the world, and in the oil and gas industry the term subsea relates to the exploration, drilling and development of oil and gas fields in underwater locations.

The development of subsea oil and gas fields requires specialized equipment. The equipment must be reliable enough to safe guard the environment, and make the exploitation of the subsea hydrocarbons economically feasible. The deployment of such equipment requires specialized and expensive vessels,

which need to be equipped with diving equipment for relatively shallow equipment work (i.e. a few hundred feet water depth maximum), and robotic equipment for deeper water operations. Any requirement to repair or intervene with installed subsea equipment is thus normally very expensive. This type of expense can result in economic failure of the subsea development.

Most common solution provided by IRIZAR are forged mooring components used for Subsea Industry. Mainly, Plet Hooks, Quick Connect Hooks, Chain Hooks, ROV Hooks, Shackles and Chain Link & Swivels.

In all cases, safety factors are extremely important due to the high specifications required. IRIZAR standard safety factors are 1 to 5 showing high performance level for toughest environments on most deep waters. Thus, current certifications from ABS, and DNV as chain accessories provides required guarantee in order to be chosen as high prestige partner for mooring forged components.
