What CS MARINE CONSTRUCTORS, INC. does
CS Marine Constructors, Inc. is a Northern California-based marine construction contractor founded in 1986 by Chuck Stockon, a civil engineer. The company builds and repairs marine infrastructure — piers, wharfs, docks, dolphins, walkways, gangways, intakes, and outfalls — for enterprise clients including oil refineries, marine terminal operators, state and local agencies, and the US Coast Guard. CS Marine is a wholly-owned subsidiary of Woocheen Commercial Services, the commercial arm of Sealaska, an Alaska Native Corporation owned by approximately 25,000 Tlingit, Haida, and Tsimshian shareholders, which gives it 8(a) small business status, DOD Indian Incentive Program eligibility, and a credentialing stack (ISNetworld, PICS, Avetta, OSCA, DISA, TWIC) that pre-qualifies it for set-aside federal and refinery work.
The company's operating platform is anchored by a 4-acre paved dockside facility at Mare Island in Vallejo, California, equipped with 30-, 40-, and 100-ton yard cranes, plus a fleet of marine assets including the CSM DB Ventura (94 short-ton lifting capacity, 148-foot boom), CSM DB Carquinez (125 tons at 50-foot radius), CSM DB Mare Island, CSM DB Steadfast (30 tons at 65-foot radius), and the CSM CB 38 crane barge. Specialized equipment includes Flexifloat modular barges with optional jack-up legs, two Bardex 100-ton gripper jack skidding systems, vibratory and impact pile-driving hammers (ICE 4450, D-62, D-46, D-30, D-12), and sonar-aided debris-recovery gear for locating and recovering submerged objects. The company also provides dockside mobilization/demobilization, fabrication, sub-arc pile welding, marine demolition, salvage, and unexploded-ordnance recovery services, and maintains a California Class A General Contractor license (#507590) with $50M single / $150M aggregate bonding capacity.
Commercially, CS Marine operates a quote-based, project-by-project professional services model with no publicly disclosed pricing. Distribution is direct-to-enterprise and relationship-led; CS Marine describes itself as the preferred first-choice contractor for many Bay Area energy terminals, with multi-year contract arrangements and emergency repair capabilities. The go-to-market is supported by memberships in the Pile Driving Contractors Association, ASCE G-I, Western States Petroleum Association, Western Dredging Association, and OSHA/NASP/ASHI safety bodies. The company is currently expanding into the Long Beach area in 2023–2024 as part of a stated growth strategy and is positioning for California offshore wind port-development work tied to the state's net-zero energy initiative.
