Offshore construction is the installation of structures and facilities in a marine environment, usually for the production and transmission of oil, gas, power, electricity and other resources.

Offshore construction includes the design, construction, and/or repair of offshore structures, both commercial and military, which includes Subsea, Offshore Platforms, Floating Oil & Gas Platform and lately renewable energy (Wind Farms).

Construction in an offshore environment is a high difficult and dangerous activity. Construction and pre-commissioning is typically performed, as much as possible, on land or inshore areas. To optimize the costs and risks of installing large offshore platforms, different construction strategies have been developed.

Regarding the types of lifting appliances, the main types of cranes used are Heavy Lift with Jib, Mast, Luffing, Subsea and Heave compensation etc.

Forged components required on this environment are huge, for several purposes such as lifting (forged hooks, hookblocks and sheaves as main critical components) or fixing ( with high critical forged components) where IRIZAR is highly recognized as high level quality supplier on this Industry. Actually, certificates such as API, DNV, LRS or ABS provide its prestige as World Known Supplier for high critical and safety related technical solutions.
