Maritime Developments Ltd. (MDL) has efficiently supported Maersk Provide Service within the set up of a dynamic riser meeting offshore Brazil, marking the corporate’s largest back-deck unfold so far. The operation, carried out at Petrobras’ Mero subject within the pre-salt Santos basin, linked a everlasting reservoir monitoring (PRM) sensor grid to the deepwater subsea infrastructure.
The challenge required a bespoke engineering answer to deal with a number of parts concurrently — together with a dynamic cable riser, knowledge unit switch meeting (DUTA), pigtails, and spine cables — all deployed from 9.2-meter reels. The MDL unfold, mobilized in Peterhead, Scotland aboard the Skandi Involver, featured a Wheeled Horizontal Lay System (WHLS), a Era 2 Reel Drive System (RDS), and 4 tensioners with line-pull capacities starting from 12 to 110 tonnes.
To cut back product stress and optimize dealing with, MDL and Maersk Provide Service co-engineered a customized deck format incorporating deflectors, hydraulic winches, and a frictionless wheel mechanism for clean deployment. The configuration enabled simultaneous set up of a number of cables whereas sustaining integrity at water depths reaching 2,500 m.
“This challenge is a chief instance of how MDL’s built-in challenge providers—combining engineering know-how, in-house gear, and skilled offshore personnel—ship secure options for complicated deepwater scopes,” mentioned Euan Crichton, Senior Undertaking Supervisor at MDL. “The problem of dealing with 5 pre-terminated traces concurrently was important, however our early feasibility work ensured a strong and environment friendly execution.”
Yuri Martins, MDL’s Brazil Nation Supervisor, added that the challenge underscores the corporate’s “rising footprint in Brazil and its potential to ship artistic, secure, and technically sound options for deepwater operations.” He famous that MDL’s ongoing enlargement in-country aligns with Petrobras’ broader pre-salt improvement ambitions at Mero and different high-impact fields.
The Mero subject, operated by Petrobras (38.6%) with companions Shell Brasil (19.3%), TotalEnergies (19.3%), CNPC (9.65%), CNOOC (9.65%), and Pré-Sal Petróleo S.A. (3.5%), is certainly one of Brazil’s largest pre-salt developments and a cornerstone of the nation’s offshore manufacturing development.
