Seacor Marine has ordered "full picture" technology upgrades from Kongsberg for three platform supply vessels (PSV) from its Mexican joint venture.
The contract from Mantenimiento Express Marítimo SAPI de CV (Mexmar) to install hybrid power and dynamic positioning upgrades follows the conversion of Seacor Maya.
Under the new contract, Kongsberg will increase energy efficiency on Seacor Azteca, Seacor Warrior and Seacor Viking.
Mexmar said the works, which are expected to be completed by July, ensure it will be the sole PSV owner in the Americas to help clients meet strict environmental regulations for carbon dioxide, nitrogen dioxide and sulfur oxide emissions.
Kongsberg is contracted to supply and integrate the energy storage system with an energy control system, dynamic positioning and integrated automation system.
