In Saudi Aramco’s field development blueprint, Package 2 of the MIP (Marjan Increment Program) is a crucial part of the field expansion. It encompasses the development of oil, water and gas injection platforms, as well as the construction of a new offshore oil and gas separation plant. The consortium of Subsea7 and LTEH, as a LTA (Long-Term Agreement) partner with Saudi Aramco, was awarded to execute the full EPCIC scope of Package 2 of MIP (or “MIP-2”).
Sarens is working together with its client Subsea7 to execute the installation of the three TP topsides using the floatover method, for which Sarens have supplied a complete mooring system for floatover operation.
The winches and associated equipment were transported from Belgium to India, delivered to the port of Mundra in Mumbai, and then transported by road from Mundra to L&T's Hazira modular fabrication yard, where the topsides were loaded out to floatover barge.
The objective of the MIP (Marjan Increment Program) package 2 'Offshore Oil Facilities' (along with other MPI packages) is to increase total oil processing capacity from 600 to 800 MBCD. The Marjan Offshore field is located in the Arabian Gulf, about 85 km northeast of Tanajib and about 260 km northeast of Dhahran. It is located in medium water depths, between 29 and 52 meters.
Package 2 of the MIP (Marjan Increment Program) is a crucial part of the field expansion. It includes the development of oil, water and gas injection platforms, as well as the construction of a new offshore oil and gas separation plant, known as Marjan GOSP-4. The MIP Package-2 ‘Offshore Oil Facilities' project will provide ESP and Future Gas Lift, Tie-In Platforms and Wellhead Facilities to increase Crude Oil Production.
Sarens, world leader in heavy lifting, engineered transport and crane rental services, has collaborated with its client Subsea7 which is responsible for the installation of the three TP topsides (TP11, TP12 and TP13)in the Marjan field using the floatover method. For this purpose Sarens has been contracted by Subsea7 to supply a mooring system to assist floatover operation that includes cross wire winch, cross wire dyneema cable, docking line winch, docking winch dyneema cable, hydraulic power unit, line tension monitor, tugger winch, tugger cable, directional aids such as swivel guide and universal roller guide.
The selection of this material was made based on floatover engineering simulations, taking into account the winch capacity required for positioning the floatover barge during docking and mating operation phases. The following factors were taken into consideration: the not-to-exceed (NTE) weight for T&I engineering is 4800MT for TP11 and TP12 topsides, and 5800MT for TP13 topsides. The NTE weight excludes here the temporary T&I elements, e.g. gratings, sea fixings, etc.
The winches and related equipment were transported from Belgium to India, delivered to the Mundra port in Mumbai, and then transported by road from Mundra to L&T's Hazira shipyard. Sarens sent a supervisor and a technician to oversee the installation and commissioning of the mooring winches, barge draft sensor system, and auxiliary equipment on floatover barge at the Hazira yard.
The floatover barge transported the Topside platform from the L&T Hazira yard in India and sailed to Saudi waters for installation in the Marjan field. Sarens personnel travelled to Kingdom of Saudi Arabia and boarded the floatover barge offshore to operate the winches for positioning floatover barge during docking/mating operation. This process was repeated for the second and third Topside. All three topsides have been safely and successfully installed.
Sarens has extensive experience in both, the region and internationally in the oil & gas sector. Together with McDermott, the company took part of the heavy lifting and load out operations at Jabel Ali as well as at Batam for Marjan Field Package 1, as well as the upgrade and improvement works of PT Pertamina refinery in Balikpapan, Indonesia. Also, for North Field Oil projects (Qatar Energy) Sarens was contracted by Seatrium to conduct the weighing, loadout and ballasting for two Bridges units, two Jackets and two Topsides utilizing up to 132 a/l for the Gallaf 2 project in Batam, Indonesia.
