OOS launches multi-activity unit vessel, in talks with shipyards

Written by  OE Staff Tuesday, 14 November 2017 04:09

Dutch firm OOS Energy, part of OOS International Group, has revealed a new vessel concept, the Multi Activity Unit (MAU), a self-propelled, dynamically positioned jackup capable of performing a wide range of services.

OOS Energy says it is working on finalizing the vessel's equipment packages and in final discussions with shipyards for the construction of two units with an expected availability in Q4-2020 and Q1-2021. The first unit is to be named Luctor et Emergo.

The unit would be equipped with a high efficiency plug and abandonment (P&A) package able to perform well intervention/workover, drilling operations and performing activities simultaneous on multiple wells.

The unit is further equipped with a large accommodation and two, 1200-ton cranes, which supports in removing the majority of platforms in the Southern North Sea or other areas in the world with water depths up to 80m.

In addition, with this unit OOS Energy is able to transport and offload removed structures without the support of other vessels or heavy lift equipment. Its design and lifting capability provides an immense efficiency that can also be used in the offshore wind energy sector for installation of monopiles, jackets and turbines.

During the design OOS Energy, in cooperation with the vessel designer, ensured that for all operations the capability of the unit is maximized while keeping the size within limits.

“The strength of our concept is SIMOPS (simultaneous operations); combining P&A with heavy lift operations up to 2400-ton without the need of a marine spread or mobilizing multiple vessels is in our view a cost reducing exercise. The MAU will be available to all parties involved within the P&A/decommissioning and wind installation market. Discussions are well underway with potential clients recognizing the efficiency of this unit,” says Léon Overdulve, CEO of OOS International.
