Core offering

Scaldis provides offshore heavy lift contracting services using two specialized vessels, Rambiz (dual-crane, shallow-draft, 3,300t capacity) and Gulliver (DP2, 4,000t capacity, 78-person accommodation). The company delivers installation, decommissioning, salvage, civil construction, and renewables services for oil and gas operators, offshore wind developers, and government/infrastructure clients across European waters. Scaldis also employs a proprietary Double Duo Lift method combining both vessels to achieve 7,300 tonnes combined lifting capacity for ultra-heavy lifts such as wreck salvage.

Product overview

Scaldis is an offshore heavy lift contractor offering marine construction, installation, and decommissioning services through two primary vessels: Gulliver (DP2 heavy lift vessel with 4000t capacity and 78-person accommodation) and Rambiz (unique dual-crane vessel with shallow draft capability). The company provides five core service lines: Civil Construction Works, Oil and Gas services, Renewables and Environmental Works, Decommissioning Works, and Salvage Works. These services span offshore wind farm installation, platform decommissioning, salvage operations, and civil marine construction projects.

Partnerships

Seven partnerships are on record, tiered core and minor.

• Boskalis Offshore Marine Contractors B.V.coreStrategic or Co-development PartnerFormed a joint venture Thames JV with Boskalis to execute the decommissioning of the Thames A platform complex for Perenco UK (Q1 2015 – Q1 2018). The JV bundled forces to issue an attractive project execution schedule and combine specialized vessels and expertise for one of Scaldis's biggest decommissioning challenges.
• GeoSea NVcoreStrategic or Co-development PartnerGeoSea, described as Scaldis's sister company (both part of the DEME/Jan De Nul Group structure), partnered on the Ormonde Wind Farm project. GeoSea handled transportation, installation, and measurement of pin piles while Scaldis handled jacket transportation and installation and topside lifting. This sister-company cooperation enables combined execution of complex offshore wind farm projects.
• BOA Offshore (BOA Tugs AS)coreStrategic or Co-development PartnerBOA Offshore was a key consortium partner in the salvage of the Norwegian frigate Helge Ingstad. The partnership combined BOA's tugs and offshore support vessels with Scaldis's heavy lift vessels and lifting expertise to execute the revolutionary Double Duo Lift salvage operation in Bergen fjord.
• Nederlandse Aardolie Maatschappij (NAM)minorStrategic or Co-development PartnerScaldis was contracted by NAM for the complete transport and installation of the L13-FI-1 monotower in the Dutch sector of the North Sea (May 2017). The project involved pioneering the first monopile installation without the use of a gripper frame or installation template, a new methodology developed jointly.
• CBT Consortium (Consortium of Scaldis + 3 other companies)coreStrategic or Co-development PartnerCBT consortium (Scaldis Salvage & Marine Contractors NV plus three other companies) was formed to execute the salvage and removal of the Tricolor wreck near Dunkerque, France (January-November 2003). Scaldis served as a key contractor within the consortium, engineering a special nine-section cutting and removal plan for the 190m vessel carrying approximately 3,000 cars.
• THV AO Soetaers – Jan De Nul NVminorStrategic or Co-development PartnerJoint venture between Soetaert and Jan De Nul NV. This partnership was engaged for the Pierre Vandamme lock gate lifting operations in Zeebruges, where Scaldis's HLV Rambiz executed the lifting of the 2,523-tonne fourth lock door (2018) and the 2,500-tonne replacement lock gate (2019), with both operations completed within centimetre tolerances.
• THV Soetaert - Jan De NulminorStrategic or Co-development PartnerPartnership with THV Soetaert - Jan De Nul for the replacement of Lock Gate 4 from the Pierre Vandamme Lock in Zeebruges, Belgium (July 2019). HLV Rambiz lifted the 2,500-tonne lock gate from the quayside and installed it in its original position with diver assistance in approximately 14 hours.

Broad incumbents

• Van Oord: Dutch offshore contractor with strong offshore wind foundation installation capability (Aeolus, MPI vessels). Direct overlap with Scaldis in jacket and substation installation for European wind farms.
• Saipem: Italian offshore EPCI contractor with cranes and pipelay vessels operating globally in oil & gas and renewables. Broadly comparable in heavy lift and offshore installation services, though more upstream-focused.
• McDermott International: Global offshore EPCI contractor with heavy lift, transport, and installation capabilities for fixed offshore platforms. Comparable to Scaldis on oil & gas platform installation work, though typically engaged on integrated EPCI scopes.
• Subsea7: Global subsea engineering and construction contractor active in SURF and offshore wind. Overlaps with Scaldis in subsea heavy lift and renewables installation, but operates at materially larger scale across a broader portfolio.
• DEME: Belgian marine contractor and Scaldis's parent/sister company. Active in offshore wind foundation installation, dredging, and subsea rock installation — competing and cooperating with Scaldis in the same European tender pool.
• Jan De Nul Group: Belgian marine contractor (also a Scaldis parent), operating offshore installation vessels (Voltaire, Les Alizés) for foundations, cables, and substations. Joint ventures with Scaldis on lock gate and wind farm installations.

Emerging players

• Ardent (part of Svitzer / Maersk group): Marine services company with salvage and emergency response capabilities relevant to Scaldis's maritime salvage segment — directly overlapping in wreck removal and emergency response tenders.

Direct peers

• Allseas: Swiss-based offshore pipelay and heavy lift contractor pioneering Pioneering Spirit, the world's largest vessel for single-lift platform and pipeline removal. Competes head-to-head with Scaldis on North Sea platform decommissioning tenders.
• Heerema Marine Contractors: Dutch-headquartered global heavy lift and offshore construction contractor operating the world's largest crane vessels (Sleipnir, Thialf, Balder). Directly comparable to Scaldis in offshore heavy lift for oil & gas decommissioning and wind installation.
• Royal Boskalis Westminster (Boskalis Offshore Energy): Major Dutch marine contractor with offshore energy, heavy lift (Dockwise), and subsea installation services. Has a directly overlapping customer base with Scaldis (Wintershall, Perenco, Equinor) and has even JV'd with Scaldis on the Thames platform decommissioning.
