ABERDEEN, UK—Maritime Developments (MDL) has supported independent Brazilian operator PRIO (formerly PetroRio) by preparing its flexible product for offshore deployment.
The two 141-mm OD umbilicals—required as part of an imminent field redevelopment project offshore Brazil—had been located in Peterhead, Scotland, on their original storage reel. Due to the passing of time, the client required a survey of the product reel to determine its condition.
The MDL Asset Maintenance & Engineering team performed the inspection, which identified that the structure of the reel and pallets were compromised and unsuitable for offshore use. The survey also identified the product had slackened on the reel over time, reinforcing the requirement for transpooling under tension to ensure the product was ready for installation.
The follow-on scope was a turnkey project management and engineering package to relocate the umbilicals onto an installation reel, which would be suitable for offshore deployment.
The location of the reel in Peterhead meant MDL could cost-efficiently assemble a complete transpooling spread within its own quayside facility. This included an under-roller for handling the original reel and a level winder to guide the product into the MDL TTS-2/35 Series Tensioner, which fed the product under tension onto an MDL 9.2m installation reel handled by a Generation 3 Reel Drive System.
Besides the provision of equipment and experienced personnel, the complete project management and engineering package included front- end engineering with development of a project execution schedule and transpooling procedure; site layout; load-in and load-out plans; lift plans; and creation of packing arrangements on installation reel. This was followed by provision of all quayside services, risk assessments, HAZID and certification package.
Following the transpooling operation, MDL handled the transport of the fully loaded reel to the quayside for collection by a cargo vessel as well as arranging the disposal of the old reel, which relieved the client of the ongoing storage costs.
