Services
Cal Dive International Inc. owns and operates the largest fleet of marine construction vessels in the world. Our fleet consists of 19 diving vessels and 10 construction barges, which is complimented by ten portable saturation diving systems and an extensive array of mobile diving and support equipment. These assets support a workforce of more than 2,000 full time project, diving, marine and support personnel.

We have performed diving projects in the Gulf of Mexico, on both coasts of the U.S., Mexico, Canada, Trinidad and Africa. The acquisition of Fraser Diving in 2006 allowed Cal Dive to expand its global presence with operational offices in Perth, Australia, Dubai and Singapore. Cal Dive International and its most recent acquisition in 2007, Horizon Offshore, expanded its presence even farther into West Africa and Southeast Asia.
Cal Dive International has been a leader in the domestic subsea construction industry for many years. Through strategic acquisitions and selective recruiting, Cal Dive has developed a construction group focused on marine construction and diving. The company has employed highly experienced, performance-oriented offshore employees. The project management team, along with the shore – based support group, are dedicated to servicing the clients needs for planning, engineering, quality control, and safe operations. Due to the diversified nature of services and the enormous resource base provided by Cal Dive International, the company is able to offer a full range of solutions for most marine construction projects.
Cal Dive has earned a solid reputation for safe quality work over its 31 years of experience. As the largest commercial diving company in the world, we can do it all.
