Heerema Marine Contractors will put its semi-submersible crane behemoth Sleipnir through its paces at the Marjan oil and gas field is located in the Arabian Gulf off the eastern coast of Saudi Arabia. Heerema has been tagged by McDermott to transport and install six large jackets for Saudi Aramco’s Marjan increment program.

The Marjan increment program is an integrated development project to increase the production capacity from the Marjan offshore field, with the HMC award being part of the Package-1 of a larger EPCI contract Saudi Aramco awarded to McDermott in 2019.

Heerema to leverage Sleipnir’s capabilities for the job

Heerema’s contract includes the transportation and installation of six jackets, piles, and boatlandings, which make up part of the GOSP complex. The jackets are all within the weight range of 4,500 to 6,700 metric tons with a maximum footprint of 90 x 52 meters.

Heerema will transport the jackets from the L&T yard in Oman to the Marjan offshore field using the company’s H-591 barge. The installation vessel will be Heerema’s largest semi-submersible crane vessel Sleipnir, which runs on emission-reducing LNG and has a lifting capacity of 20,000 metric tons.

Sleipnir will lift install the jackets and the 92 piles, which have a combined weight of 24,000 metric tons, in 2023.

The project will be run from Heerema’s Leiden Office and the soon-to-be-established Al Khobar office as the company pursues its ambition to expand activities in the Middle East further.
