The scope entails the development of an integrated spread of equipment and expert personnel to support installation of a dynamic riser assembly, which will enable connection to a grid of PRM (Permanent Reservoir Monitoring) sensors over wells of Mero 1 and Mero 2 projects in the basin鈥檚 ultra-deep waters.
Besides the dynamic cable riser, complete with DUTA and pigtails, the PRM network also consists of backbone cables and over 650km of seismic array cables.
To support Maersk Supply Service, MDL will supply a horizontal SURF lay spread onto an MSS I-Class vessel, with the installation campaign planned for 2025.
Prior to this award, MDL had been commissioned to undertake a FEED study to assess the feasibility of installation of the unique product in the PRM network, with the umbilical, DUTA and pigtails being supplied pre-connected - meaning that the 5 pigtail lines must be installed simultaneously.
Alexander Wilson, MDL Flexlay Solutions Unit Lead, said:
鈥淎s a result of completing the FEED, MDL had an intimate knowledge of the project and the challenges faced by Maersk Supply Service, and we were therefore best placed to hit the ground running with the most achievable approaches within the client鈥檚 timescales.
鈥淗aving performed the study, we appreciated the substantial challenge of a parallel installation of five pigtails, a dynamic umbilical and DUTA, supplied as a continuous product from a single reel.
鈥淭hrough open and in-depth technical discussions between the two companies, we were able to identify a solution, utilising our proven back-deck technology, known for its safety and integration features which will provide reassurance on such complex multi-system installation.
鈥淥ur experienced project engineering team will assist with the packaging of the spread on the client鈥檚 vessel while our expert field service team will ensure safe operations on board, supported with remote connectivity to the beach.鈥�
Yuri Mendes Martins, MDL do Brasil Country Manager, said:
"We are pleased that MDL has been chosen to deliver a solution for this complex installation, where we were able to assist from the early planning stages with our in-house engineering expertise. When faced with a challenging scope like this one, being able to perform feasibility studies on the most optimal approaches is invaluable in delivering a safe and successful project overall.
鈥淭his award represents the confidence that Maersk Supply Service has in MDL鈥檚 abilities to provide innovative and reliable solutions. Brazil's ultra-deep waters require companies that can meet these complex challenges head-on and MDL is uniquely equipped to do so.鈥�
Alexandre Ferraz, Country Manager for Maersk Supply Service Brazil, said:
鈥淭he installation of the dynamic riser in conjunction with DUTA and pigtails contains technical and operational challenges that can only be overcome with an effectively designed and integrated lay system. Maersk Supply Service was able to build a collaborative partnership with MDL that gives us confidence that project will be delivered successfully.鈥�
*The operation of the unitised Mero field is conducted by the Libra Consortium operated by Petrobras (38.6%), in partnership with Shell Brasil (19.3%), TotalEnergies (19.3%), CNPC (9.65%), CNOOC (9.65%) and Pr茅-Sal Petr贸leo S.A (PPSA) (3.5%), as the Brazilian Government's representative in the non-contracted area.
