99 MW Wind Farm — Cable Laying & 10 m+ Trenching with In-House Vertical Injector
Concept, build and offshore operations in 9 months for LS Marine Solution — South Korea's first fully CPS-deployment quadrant + A-frame system, a 10 m-burial Vertical Injector, plus cable-lay mobilisation and a retractable-thruster upgrade on the lay vessel — turnkey on the 99 MW Jeonnam wind farm.
For LS Marine Solution, design, build and operate South Korea's first fully CPS-deployment quadrant and A-frame system, plus a 10 m-burial Vertical Injector — all inside a 9-month window that also had to absorb full cable-lay system mobilisation and a retractable-thruster upgrade on the lay vessel. New equipment, new vessel configuration, and offshore execution on the 99 MW Jeonnam wind farm — concept to last splice.
For the JN1 Offshore Wind Project in Jeonnam, Korea, Dimension delivered a complete turnkey solution covering engineering, project management and offshore operations. The team pioneered the design of a custom Vertical Injector (VI) for efficient cable burial and executed a seamless shore-end pull-in combined with simultaneous cable laying.
Each export cable operation featured a 600 m float-out, precise barge beaching at KP 0.6, and nearshore vessel manoeuvring using advanced mooring patterns. Leveraging the in-house VI, Dimension achieved an impressive burial depth of up to 9–10 m — setting new standards for reliability and performance.
