London Marine Consultants (LMC) has secured a $110m contract from Sembcorp Marine’s Jurong Shipyard to deliver an external turret mooring system for the Libra oil field’s floating production, storage and offloading (FPSO) vessel.

The deal requires Ezra Holdings subsidiary LMC to supply engineering, procurement and construction (EPC) of the complete external turret for the extended well test (EWT) FPSO vessel.

"Under a sub-contract from LMC, OneSubsea will manufacture an advanced swivel stack in Norway."

LMC will also design the mooring lines, analyse the risers and offer engineering support for integration of the turret and swivel stack onto the FPSO at Jurong Shipyard.

Ezra said engineering and project management are underway in the group’s London office, with turret fabrication planned to be completed at Triyards in Vietnam.

Under a sub-contract from LMC, OneSubsea will manufacture an advanced swivel stack in Norway.

Six swivels, including two high-pressure gas injection swivels, will be used during integration of the complete turret onto the FPSO in the first quarter of 2016.

Jurong Shipyard secured a contract from OOGTK Libra, a joint-venture (JV) between Brazil’s Odebrecht Oil & Gas and Teekay Offshore, to convert the Navion Norvegia shuttle tanker to form the Libra EWT FPSO.

The JV firm will own and operate the FPSO, chartering it to Petrobras for twelve years, excluding options.

The Libra field is a large, ultra-deepwater oil prospect situated in the Santos Basin, approximately 230km off the coast of Rio de Janeiro, Brazil, north of the Tupi field.

The oil field is expected to contain recoverable resources ranging between eight billion to 12 billion barrels of oil.
