OOS International offers a fleet of heavy lift vessels in accordance with the best professional standards, striving to provide the most effective and added value solutions to our customers’ satisfaction.
Our units are built to meet the highest requirements for offshore heavy lifting, with capacities of 3600 tons (two Huisman cranes) at the OOS Gretha and 1100 tons on board of the OOS Prometheus.
The semi-submersible hull shapes of the units are the pride of our company, which enables us to work efficiently and make us reliable on achieving our commitments towards heavy lifting jobs.
Our stable and dynamic vessels can install numerous fixed- and floating structures in both shallow- and deep water.
Our fleet of unique crane vessels provide a reduction of weather downtime due to our semi-submersible hull shapes as well as 25% less fuel consumption due to brace less hull design. Accommodation is available during hook-up support. The vessels have a dual crane capacity for installation of integrated decks. The large work deck space and vessel motion behaviour ensure a safe working environment for all people on board. They can also be used for transportation of modules and equipment on deck of the crane vessels, reducing costs and improving workability.
OOS International offers our clients turnkey solutions when it comes to cost effective decommissioning services, integrating offshore accommodation facilities with heavy lift capacity. This unique combination makes OOS International the preferred partner for your potential decommissioning projects.
Decommissioning projects of offshore installations are very complicated, often even more than the original installation itself. The condition of the platform throughout the years, the utility and safety systems, its residual strength and actual weight must all be assessed and taken into consideration. OOS International can be your ideal business partner for these processes.
OOS International provides full range of solutions for the oil majors, with the combination of heavy lifting cranes, large deck space and self-propelled vessels to offload the project cargo onshore.
Other important advantages of our units are the ability to accommodate large number of project crew and the vessels have a large deck space which is ideal for the storage of steel structures.
OOS International guarantees that our multi-purpose Semi-Submersible Crane, Construction- and Accommodation Units are the ideal central piece in every decommissioning project worldwide.
Our services consist of project engineering, heavy lifting and accommodation, developing safe and effective methods for removal and offloading of offshore structures such as jackets and topsides.
