Houston operator Helix Energy Solutions has scooped a huge charter deal for well intervention vessels in Brazil.

The New York-listed company said it has fixed out the 158-loa Siem Helix 1 and Siem Helix 2 (both built 2016) to state-owned energy group Petrobras for an initial three years.

These deals are worth a combined $786m, Helix added.

There are also options for a further three years each.

The contract value equates to a rate of $358,000 per day for each ship.

“The contracts were entered into following a competitive tender process,” Helix said.

The Siem Helix 2 has been working for Petrobras since 2017 in the Santos and Campos basins, completing more than 100 well interventions.

The sister vessel previously worked for Petrobras from 2017 to 2021, completing 74 well interventions in the same area.

Daniel Stuart, Helix’s vice president of commercial, said: “We have built a long and productive working relationship with Petrobras for the last seven years.

“During this time, we have consistently delivered safe and cost-effective well intervention services to the Brazilian market.”

The Siem Helix 1 and Siem Helix 2 are purpose-built ships owned by Christen Sveaas’ Sea1 Offshore in Norway.

They offer a wide range of subsea services, including production enhancement, well decommissioning, subsea installation, offshore crane and remotely operated vehicle operations, offshore construction and emergency response.

Helix also owns its own fleet of six offshore ships, including multipurpose support vessels.
