► Offshore crawler cranes

Secure massive heavy-lifting capacity on deck, barge, or quay.

Large-scale offshore campaigns require uncompromising power, extensive reach, and absolute stability. Our fleet of heavy offshore crawler cranes (70T to 1000T) provides the brute lifting capacity and long-reach lattice boom configurations needed to execute ultra-heavy lifts, wind turbine installations, and deepwater salvage operations under your own control.

Uncompromising power. Proven offshore stability.

Unlike compact cranes designed for tight spaces, our heavy crawler fleet is engineered for maximum load moments, immense reach, and continuous duty-cycle performance. By integrating a heavy-duty crawler crane onto your project asset, you gain:

► Ultra-Heavy Lifting & Reach:
Execute massive lifts up to 1000 tons with high-reach lattice boom and telescopic configurations.

► True Duty-Cycle Durability:
Built with robust high-torque power units and heavy-duty winches for continuous grab, dredging, and decommissioning cycles.

► Excellent Load Distribution:
Tracked crawler bases enable optimal weight distribution and allow the crane to travel under load on reinforced decks or barges.

Four ways Heavy Crawler Cranes drive offshore project success

►Offshore Wind & Foundation Installation

Deploy our heavy lattice boom cranes (up to 1000T) directly on vessels or barges to safely lift and position heavy monopiles, transition pieces, and wind turbine components.

►Large-Scale Decommissioning & Salvage

Handle high-weight platform jackets, topsides, and wreckage. Equipped with extreme line pull capacity, our cranes seamlessly support heavy shears, underwater cutting tools, and zware berging operations.

►Heavy-Lift Barge Integration (Floating Crane Upgrades)

Convert flat-top barges or transport vessels into highly capable floating crane assets. We design and install custom load-spreading grillage to safely mobilize heavy rupskranen onto your deck.

►High-Volume Grab & Dredging Support

Utilize our heavy-duty cycle (HD) crawlers for continuous bulk operations. Designed for high dynamic loads, these machines are ideal for heavy grab work, dredging support, and subsea rock installation.

Frequently asked questions

1. What are the primary applications for an offshore crawler crane?

Our crawler cranes are utilized for heavy offshore construction (wind farms, oil & gas platforms), decommissioning campaigns, coastal/quay civil works, and as temporary deck cranes on barges, pontoons, or work vessels.

2. How do you calculate deck load and structural integration on a barge or vessel?

Our in-house engineers perform all necessary structural analyses beforehand. This includes deck load calculations, designing customized load-spreading grillage, and seafastening arrangements in accordance with international maritime standards.

3. Can Dutch Offshore support Marine Warranty Surveyor (MWS) reviews?

Yes. We provide complete technical documentation packages, including certified offshore load charts, stability calculations, lift plans, and risk assessments (HAZID/HAZOP) to ensure quick approval by MWS and end-clients.

4. How does Dutch Offshore maximize crane uptime during projects?

We take a proactive approach to operational uptime. Every project is supported by a dedicated container stocked with critical spare parts on-site. Our crane operators are trained in first-line troubleshooting to resolve minor issues immediately without waiting for external technicians. Combined with our commitment to deploying new-generation machines and 24/7 remote support, we consistently achieve industry-leading availability rates throughout the project duration.

5. How do crawler cranes handle dynamic vessel motions at sea?

For marine deployment, our cranes are programmed with specific offshore load charts. These charts account for vessel motions (roll, pitch) and dynamic amplification factors based on the specific sea state and wave heights.

6. What is the typical mobilization time for a large offshore crawler crane?

Despite their massive size, cranes like the Liebherr LR 1500 and LR 11000 are engineered for efficient transport and rapid assembly, minimizing mobilization time in port and keeping your schedule on track.

7. What certifications do your crawler cranes carry for offshore operations?

All our cranes are prepared and certified in full compliance with NEN 13852 (offshore crane standards) and other applicable regulations including EN 13000, LOLER, and class-specific requirements. We ensure all documentation, load testing, and structural inspections are current and survey-ready prior to mobilization.

8. Can crawler cranes operate on Dynamic Positioning (DP) vessels?

Yes, our fleet is highly compatible with DP vessels and anchored barges. We perform specialized motion and stability analyses for each specific hull to guarantee safe operations.

9. Do you provide custom rigging and lifting gear along with the cranes?

Yes, we can supply a complete, certified rigging package (including heavy-duty slings, shackles, and custom spreader beams) specifically tailored to your project’s lifting requirements.

10. What kind of maintenance and breakdown support is provided during rental?

Every rental includes 24/7 technical support, a project-dedicated spares container on-site, and operators trained in first-line diagnostics and troubleshooting. For issues beyond field repair, our service team mobilizes within the shortest possible timeframe. We focus on prevention: regular inspections, condition monitoring, and new well-maintained equipment reduce unplanned downtime to an absolute minimum.
