Vallejo Crane Crews: From Mare Island Docks to the Carquinez Strait

Shipyard lifts and the jurisdiction line

Ship repair at Mare Island has relied on dry docks, wharf cranes, mobile cranes and a great deal of rigging for propellers, shafts, rudders and deck equipment. It also puts crews right at the boundary between two regulators. On shore and on the wharf, Cal/OSHA's Title 8 governs. Work on a vessel afloat in navigable water generally belongs to federal OSHA's shipyard and maritime standards.

A competent rigger is valuable in either setting. Ship components are irregular, centers of gravity are hard to judge and attachment points are not always obvious, so the Rigger Level II course and its focus on load calculation and lift planning fits this work well.

Building next to the water

The 2003 Carquinez Bridge, a suspension span named for ironworker Alfred Zampa, replaced a 1927 cantilever and is a reminder of how much heavy marine construction this stretch of I-80 has seen. Waterfront redevelopment on Mare Island and along the Vallejo shoreline brings similar challenges at smaller scale: pile driving, seawall and pier repair, and building foundations on reclaimed tidal land.

That reclaimed ground can be soft and prone to liquefaction in strong shaking. Plan for mats, verify the bearing capacity and watch for settlement around cribbing during long picks. Wind funnels through the Carquinez Strait on summer afternoons and can catch long or flat loads.

Vallejo's ferry terminal on the Napa River is another waterfront asset that needs periodic float, gangway and pile work, typically done from a barge or the shore with a mobile crane. Tides, current and passing vessels all affect timing, so these lifts are scheduled tightly and planned with the ferry operator.

Your path to certification

California's version of the rule is worth stating plainly: no state agency licenses you, yet Title 8 bars employers from assigning a covered mobile or tower crane to anyone without a current accredited certificate for that type.

• Pick the crane type. Truck, crawler, boom truck and tower cranes each have their own certification category. The mobile crane operator course covers the most common types.
• Study for the written exams. Work through the course material and practice questions on your phone or computer.
• Schedule exams with the certifying body. Written tests can be online-proctored; the practical is hands-on at a practical test site.
• Keep it current. Certificates last up to five years. Check the California requirements guide for how the state handles recertification, then plan your recertification prep.
