With 26 ships carrying millions of passengers on two- to 24-day voyages departing from every US coast, Carnival is currently the world’s largest cruise line. In 2017, during a resurgence in the cruise industry, the company announced it would be expanding the operation of its Long Beach, California terminal in and around the giant white dome that was once home to the museum for Howard Hughes’ Spruce Goose airplane.

The Carnival cruise terminal had previously occupied a portion of the iconic geodesic dome, but the expansion would more than double its capacity. Envise was tapped to assist with the considerable mechanical and building automation controls retrofit scope of the project. In addition to the unique challenges presented by the 150-foot dome structure, the terminal needed to remain fully operational during all construction.


As part of the massive mechanical retrofit, Envise furnished and installed two 75-ton air cooled chillers, two 75-ton air handlers, and two 500,000 BTU boilers, along with associated VAVs throughout the facility and over 1200 feet of new chilled water piping.

Envise also installed a new Delta building automation system and provided a host of value-engineered options that helped bring down the overall cost of the project to the owner. This included assistance with the design and installation of the intricate relief fan system. Located at the top of the dome, four large pressure relief fans ultimately had to be flown in and set via helicopter.

Most critically, all work was completed while the Carnival terminal remained fully operational, with cruises embarking and disembarking from Long Beach five days a week.

Following the success of the project, Envise was awarded a preventative maintenance contract covering all mechanical equipment and the new building automation system.

I’m most proud that we were able to complete the project without any delays to our ships. Envise really helped us with the logistics of the construction in order to maintain our operations through that whole period. And now that they’ve stayed on as our maintenance contractor, we rely on them heavily to provide that value of air conditioning and comfort control for all of the 1.5 million guests that pass through here each year.
