(WO) — Maritime Developments Ltd. (MDL) has accomplished a deepwater subsea umbilicals, risers and flowlines (SURF) decommissioning marketing campaign in Brazil’s Campos basin, recovering infrastructure related to a decommissioned FPSO.
The marketing campaign was carried out roughly 250 km east of Rio de Janeiro from a multipurpose vessel already beneath constitution by the sphere operator. The scope included restoration of versatile flowlines, umbilicals and jumpers, with MDL offering the back-deck gear unfold, engineering providers and offshore personnel.
The venture adopted an earlier feasibility and front-end engineering design (FEED) research by MDL to find out whether or not the operator’s present vessel may carry out the decommissioning work. The research assessed restoration strategies, product top-tension necessities, reel capability, deck structure and preliminary structural necessities.
For offshore execution, MDL deployed its Wheeled Horizontal Lay System (WHLS-02), 110-metric-ton tensioner, Era 3 Reel Drive System, FRN-150 offshore winch and offshore-rated reels. The gear was mobilized in Brazil and operated by MDL personnel from Brazil and the UK.
The WHLS makes use of a wheeled overboarding association designed to scale back the capstan impact throughout deepwater SURF retrieval. In accordance with MDL, the configuration enabled a single high-capacity tensioner to deal with restoration a great deal of as much as 105 metric tons.
“This venture progressed from an early feasibility research by means of to offshore execution, permitting MDL to help the shopper all through the complete venture lifecycle,” stated Yuri Mendes Martins, MDL Brazil nation supervisor.
Martins stated deploying MDL’s moveable gear aboard the client-selected vessel decreased reliance on specialised building tonnage and supplied better flexibility over venture schedules and prices.
The marketing campaign provides to MDL’s subsea decommissioning work in Brazil as operators tackle a rising stock of mature offshore infrastructure.
