Operation times will be five to six days per week, with hours of operations 5am to 7pm(local). This operation will include the use the following vessels and equipment: 40x80 PC650-01, 40x80 PC650-02, Crane Barge MICHEAL LIND, Staging barge STELLA LIND, Tug CASSIE LIND, Tug ARCHIE LIND, SEVENSON 01 and 02 work boats. The project location is centered at approximately at the San Francisco Pier 41 to Pier 43, in position: 37°48'35.20"N; 122°24'46.41"W. All vessels and equipment on site will monitor VHF-FM Channels 13, 14 and operating on 11. Sevenson will utilize two 40x80 barges with PC650 excavators on them to perform environmental dredging and capping via clam shell bucket and conventional buckets. Sevenson has hired Lind marine to subcontract out work including the transloading operations via E-Crane “Greta Jean Lind”. The Michael Lind (Crane Barge) will be in the area for support, along with another spud barge “Stella Lind” for staging room. Steel pipe pile will be installed roughly up to 400 ft offshore to hold the turbidity curtain. During the project, we will also install 504 wooden piles for slope stability. The PC650 will load into 6x – 100CY (30’ x 40’) scows and pushed to the edge of the curtain. From there the E-Crane will take the material and transload into large Jumbo Hoppers. Lind Marine will use the Cassie Lind (1200 HP tug) to push the scows up to Birds Landing, CA to an offload facility. At the offload facility there will be an E-Crane to offload the material from the scows onto land. Lind Marine will use the Cassie Lind (1200 HP tug) to push the scows up to Birds Landing, CA to an offload facility. At the offload facility there will be an E-Crane to offload the material from the scows onto land. Lind Marine will also use the Cassie Lind to push scows to Redwood City, CA to an offload facility.
