SL900 Test May 2026

Conbit tests the SL900 modular offshore lifting system in a new configuration, enabling 10‑tonne lifts at 30 metres and supporting safe, flexible vent stack removal offshore.

SL900 Test May 2026

Testing the SL900 Lifting System in a New Configuration

Conbit will carry out a new load test of the SL900 lifting system in the first week of May, validating the system in a different configuration than previously tested. In this setup, the SL900 will be capable of lifting 10 metric tonnes at a radius of 30 metres, demonstrating its flexibility and adaptability for offshore decommissioning and modification scopes.

Following a successful test campaign, the system will be transported to an offshore facility where it will be deployed to remove an existing vent stack, a critical operation requiring precision, reliability, and well‑controlled lifting behavior.

Load Testing Campaign and Visitor Opportunities

The load test will take place at Conbit’s facilities during the first week of May, with opportunities for clients and partners to attend on:

  • Wednesday 6 May
  • Thursday 7 May
  • Friday 8 May

Visitors will have the opportunity to observe the system in operation, review the test setup, and discuss the engineering considerations behind the selected configuration. The load test will confirm structural integrity, system response, and operational margins prior to offshore mobilisation.

Modular Design Enabled by Additional Boom Sections

For this configuration, additional boom sections have been manufactured by Abuco, expanding the reach of the SL900 while maintaining controlled load paths and system stiffness. The modular nature of the lifting system allows Conbit to adapt the same base equipment to different load cases, radii, and offshore constraints without the need for entirely new assets.

This approach significantly reduces lead times and enhances responsiveness when project requirements evolve, an increasingly common scenario in offshore brownfield environments.

The Relevance of Modular Offshore Lifting Systems

Modular offshore lifting systems such as the SL900 play a key role in modern offshore construction, maintenance, and decommissioning projects. Their relevance lies in several core advantages:

  • Configurational flexibility to match varying load weights and radii
  • Efficient transport and installation, especially in constrained offshore locations
  • Reduced reliance on heavy offshore crane vessels for medium‑weight lifts
  • Repeatability and scalability, allowing systems to be reconfigured across projects

By combining proven base designs with project‑specific modular elements, operators can achieve safe and efficient lifting solutions tailored precisely to the task at hand.

From Onshore Validation to Offshore Execution

This upcoming test marks an important step from onshore validation to offshore application. It demonstrates how modular lifting concepts, supported by thorough engineering and testing, enable controlled offshore removal operations, such as vent stack decommissioning, while managing risk, cost, and operational complexity.
