WTIV jacking, leg-handling and preload system
WTIV 잭업·레그취급·프리로드 시스템
The jack-up system of a wind turbine installation vessel: giant legs lower to the seabed and lift the entire hull clear of the waves, creating a stable platform for crane work.

- Family reference-profile markers
- ● 0 Standard · ○ 0 Common · △ 1 Variant · 20 unmarked
- Component coverage
- 6 released source-BOM records
- Relationship meaning
- Family markers describe reference applicability. Component links are released source-BOM listings and do not assert complete engineering containment.
FAMILY REFERENCE APPLICABILITY
Family profiles carrying a source marker.
Unmarked Families are not listed; an unmarked cell means “not normally fitted” in the source Family profile, not confirmed absence from a vessel.
RELEASED SOURCE-BOM LISTING
Released Component records.
Coverage is partial and Family-independent: selecting a Family does not alter the Component records linked to this System.
Jacking units
잭업 유닛The units that climb the legs, lifting the entire hull clear of the water on a stable working platform.
Design dependent · As required / design dependentView Component record →COMP-953 · MechanicalLegs and spudcans
레그·스퍼드캔The long legs and their seabed feet, which must carry the whole vessel's weight on uncertain ground.
Design dependent · As required / design dependentView Component record →COMP-954 · ActuatorRack-and-pinion / hydraulic drives
Rack-and-pinion / 유압 drivesThe drives providing jacking force, either continuous rack-and-pinion or stepping hydraulic systems.

Preload 탱크 and 펌프Ballast used to deliberately overload each leg before working, proving the seabed will not give way later.
