Marisco

What Marisco does

Marisco, Ltd. is a privately held, family-owned full-service shipyard headquartered in Kapolei, Hawaii, operating continuously since approximately 1975 and serving as the state's largest shipyard under the brand "Hawaii\'s Premier Shipyard." The company provides ship repair, drydocking, machining, welding, pipefitting, mechanical, electrical, industrial, and preservation (sandblast/painting) services to U.S. federal defense agencies — including the U.S. Navy, U.S. Coast Guard, U.S. Army, and Military Sea Lift Command — as well as commercial marine and industrial clients operating in Hawaiian waters.

The company\'s core infrastructure comprises three floating dry docks (Peleke Nui, Lil Perris, and Skipper) with a combined lifting capacity of 15,500 long tons, anchored by Peleke Nui, the largest dry dock in Hawaii at 454 feet by 151 feet. Marisco holds multiple industry certifications critical to military and commercial marine work, including SSPC-QP-1, SSPC-C7, SSPC-C12, SSPC-C13, and SSPC-C14 for preservation services, as well as AWS, ABS, and NAVSEA certifications for pipefitting, and ABS-approved propulsion shafting cladding weld procedures. In-house capabilities span large-capacity machining (lathes, milling machines, propeller shaft straightening up to 70 feet), crane support up to 155 tons, PCMS tile installation, and certified blasting and coating operations.

Marisco generates revenue through project-based contracts awarded via federal procurement processes and direct commercial negotiations, with no publicly disclosed pricing or revenue figures. The company operates an enterprise field sales motion targeting government and commercial marine sectors through direct relationships and competitive bidding, including a recently announced partnership with Pacific Shipyards to jointly bid on U.S. Army contracts. The company is independently owned by the Anawati and Stewart families, with no external private equity or parent company involvement disclosed.
