OSM Thome has officially launched its professional services for a groundbreaking next-generation, ultra-large cable-laying vessel (CLV). Undertaking a comprehensive scope of work, OSM Thome is fully responsible for both the critical drawing approval stage and the subsequent on-site construction supervision at the renowned Tersan Shipyard in Yalova, Turkey. The high-spec vessel is being built for South Korea-based subsea cable installation specialist, LS Marine Solution.
Marking a major construction milestone, the official steel cutting ceremony was held at Tersan Shipyard on 5 June 2026. The milestone event was personally attended by Mr. Douglas Dalli, Managing Director for Projects & New Building Supervision at OSM Thome and Mr. Frane Pilic as the site manager for site team, alongside a distinguished delegation from the shipowner. This executive presence included the CEO of LS Cable & System (parent company of LS Marine Solution), the CEO of LS Marine Solution (Mr. Kim ByungOk), and the Managing Director of LS Marine Solution, Mr. Lee GeunChang(who also coordinated with teams in Busan). Joining the executive delegation on-site at the Tersan yard were key technical and project management representatives from LS Marine Solution, including Mr. JD Hong, Mr. IK Kim, and Ms. Irem.
Speaking from the event, Mr. Douglas Dalli expressed great enthusiasm for the project’s progression: “We are incredibly proud to partner in the project management of this landmark vessel. Witnessing the steel cutting firsthand underscores the hard work our teams have already put into the ongoing plan approval phase. Managing the development of such a complex, specialized ship requires top-tier technical expertise from day one. Delivering both rigorous drawing approvals and comprehensive site supervision reflects OSM Thome’s commitment to driving green maritime innovation and supporting the global transition to renewable energy infrastructure.”
From Blueprints to the Shipyard Floor
Demonstrating end-to-end project leadership, OSM Thome’s engagement ensures strict quality control at every phase of development. Leading up to the steel cutting milestone, the specialized team has been heavily involved in the plan approval process, including meticulous drawing approvals and equipment selection to ensure all design specifications align with the highest international standards. Moving forward, OSM Thome’s site supervision team will manage day-to-day inspections, quality assurance, and safety milestones directly on the shipyard floor.
A Proven Track Record at Tersan Shipyard (2019 – Present)
This contract further solidifies the long-standing and highly successful partnership between OSM Thome and Tersan Shipyard, which began in 2019 and continues robustly to this day. Over the years, OSM Thome has developed a deep familiarity with the shipyard’s advanced infrastructure and operational workflows, built largely through our extensive work for core global clients.
A central cornerstone of this track record is our relationship with Fjord1, one of OSM Thome’s major and highly valued customers.
At Tersan, OSM Thome has successfully overseen the delivery of a substantial lineup of next-generation, zero-emission passenger and vehicle ferries for Fjord1 through 2024. Our strong partnership with Fjord1 remains exceptionally active today, with our teams currently managing a robust pipeline of active newbuildings at the yard, including several fully autonomous ferries scheduled for delivery through 2027. This deep expertise—combined with our historical success delivering specialized Havila LNG-fueled and battery-powered coastal cruise liners between 2019 and 2023—ensures seamless project execution for LS Marine Solution’s flagship asset.
Next-Generation Engineering & Green Innovation
Designed by Norway’s Salt Ship Design, the state-of-the-art, 148.4-meter-long vessel features a 31-meter breadth and a massive 13,000-ton carousel carrying capacity (18,800 tons total displacement). Engineered to simultaneously lay high-voltage alternating current (AC), direct current (HVDC) submarine cables, and fiber optic cables, it will be the largest vessel of its kind in Asia and one of only a few globally with this advanced capability—critically reinforcing LS Marine Solution’s subsea installation power across the Asia-Pacific region.
True to its green maritime focus, the design incorporates cutting-edge technologies to minimize its environmental footprint. Key features include:
- Hybrid Propulsion System: Integrated battery power for peak shaving and spinning reserve backup during critical dynamic positioning (DP) operations.
- Regenerative Power: Fully electric ship equipment designed to regenerate power back to the vessel during cable-laying operations.
- Optimized Power Management: A diesel-electric system featuring six generator sets paired with an automatic power management system that continuously selects the most fuel-efficient engine combination.
- Advanced HVAC System: Advanced climate control equipped with heat recovery technology for the accommodation spaces, significantly cutting down onboard energy consumption.
With drawing approvals and design evaluations running at full steam alongside the newly commenced production, construction is expected to span approximately three years, with the vessel scheduled to enter full operations in 2028.
