Following her high-stakes, dramatic technical slipway launch in May 2026, Lürssen’s 101.4-metre Project Ziggy has officially left the heavy metalwork phase behind. Flown under the American and Canadian flags into the River Eider, the 4,018 GT hull has now been safely guided into the climate-controlled outfitting docks at Lürssen’s Rendsburg facility.
With a final handover locked in for 2028, the next two years represent a meticulous transformation from a raw, architectural steel shell into a highly technical, “seven-star” floating private island.
The upcoming installation schedule highlights exactly what will be happening inside the shed over the next 24 months.
1. Phase 1: Locking Down the Mechanical Heart (Mid-to-Late 2026)
Before any interior joinery or paint can touch the vessel, the heavy engineering infrastructure must be locked in place. The hull’s primary mechanical components are currently being permanently aligned and integrated.
- Propulsion Alignment: The twin MTU 16V 4000 M65L diesel engines—delivering a combined 6,092 horsepower—are being precisely matched to the twin-screw propeller shafts. Because even a fraction of a millimeter of misalignment can cause devastating hull harmonics and vibrations at cruising speed, this installation takes weeks of laser-guided precision.
- Auxiliary Power Infrastructure: To support what Lürssen describes as a resort-style layout, the engine room will be fitted with massive electrical generator banks. These units must sustain high-capacity HVAC systems, complex automated pool filtration networks, and the immense hotel loads required for long-range cruising.
- The “Veins” of the Ship: Technicians are already laying down the primary grid—miles of heavily insulated electrical trunking, fiber-optic data loops for the bridge and custom cinema, black-and-grey-water plumbing, and exhaust routing.
2. Phase 2: Structural Glazing and Hull Fairing (Early-to-Mid 2027)
By early 2027, the focus shifts to the yacht’s exterior styling, specifically the material harmony of “glass and steel” envisioned by British design studio Harrison Eidsgaard.
- The Structural Glass Challenge: Project Ziggy is slated to feature some of the largest panes of structural glazing ever mounted to a Lürssen superstructure. These installations are a massive engineering feat; the mounting channels must use highly specialized, flexible adhesives that allow the glass to remain structurally isolated from the natural twisting forces (torsional flex) of the steel hull in heavy seas.
- The Sanding Gauntlet: Simultaneously on the outside, teams will begin the grueling process of hull fairing. This requires applying hundreds of pounds of epoxy fairing compound across the 101-metre steel flanks, followed by weeks of manual block-sanding. The goal is to eliminate any minute weld distortions so that the final topcoat of paint reflects light flawlessly.

3. Phase 3: The Interior Build-Out & Luxury Spaces (Late 2027)
Once the yacht is entirely weatherproof and the heavy welding is complete, Harrison Eidsgaard’s custom interior will begin to arrive at the shipyard in modular segments.
- Acoustic Isolation (Floating Rooms): To achieve a completely silent interior, the staterooms are not attached directly to the steel hull. Instead, installers will build a complex grid of rubber shock mounts to create “floating floors” and walls. This breaks the acoustic bridge, absorbing engine hum and pump vibrations.
- Resort Fit-Outs: Artisans and joiners will move in to assemble the custom wood, stone, and leatherwork across the massive full-beam sky lounge, owner’s deck, and the specialized lower-deck wellness areas. Concurrently, the cascading aft deck spaces will see the mechanical installation of the tiered swimming pools and the amphitheater-like beach club.
4. Phase 4: Final Systems Integration & Pre-Trials (Early 2028)
As the two-year outfitting gauntlet nears completion in early 2028, the yacht will transition into a live ecosystem.
- System Awakening: Every pump, valve, chiller, and automated door will be powered up individually for factory acceptance testing.
- The Unveiling: Finally, Ziggy will leave the outfitting bay clad in her permanent livery, dropping her temporary protective coverings to show off her finished metallic lines before hitting the Baltic Sea for high-stakes propulsion and maneuverability trials.
For a closer look at the shipyard milestone that kicked off this entire process, this Project Ziggy technical launch coverage offers excellent visual scale of the 101-metre hull moving down the slipway, illustrating the massive scale of the steel structure the outfitting teams are working on.
