Marine Division - History

Marine HistoryThe Geo. Gradel Co., a century plus contractor since 1903, started marine work in the late 1970's. Through company growth until now the company has accumulated 10 tugs, 25 various barges plus a compliment of cranes and excavators. The present 3rd generation sole owner of the corporation has sights set on being one of the major marine contractors on the Great Lakes. Since our start we have developed quite a clientele list with a lot of repeat business which we feel strongly is due to our ability to perform on time - quality work - within budget! This clientele nucleus including: ACOE, State DNR agencies, ODOT, BP Oil and Sunoco Refineries and large corporate shipping facilities have mandated that we operate on a highly competitive, productive and safe basis with a high quality of workmanship required. As an additional testament, since the companies inception, we have never had a project terminated. Presently the marine work is about 40 percent of the company's normal yearly volume with the balance being in site development contracting. The labor force is union with Heavy Highway AFL-CIO for a sound, well experienced and trained source of qualified employees.

The marine facilities which supports all the floating equipment includes the main dock at Jessie St. location which is a deep water dock capable of handling lake vessel shipping along with a 20 acre storage site, another dock along the Maumee river is adjacent to Toledo's shipyard which is also a deep water dock on a 10 acre site and Sandusky Ohio, a 20 acre site with a deep water dock and storage capabilities which is also a shipping point for bulk hauling (limestone) to the Bass Islands and projects near Cleveland and further east.

The main focus to date has been on the mechanical dredging operation. We have the capability to support 300 ton rated cranes with our largest spud barges and 60 ton cranes with our smallest. Tugs range from 300 to 1,800 HP, dump scows from 200 to 550 CY and ABS Certified deck barges (adorned with pigpens) rated from 500 to 1,500 tons. A complete equipment list is available.
Marine History
Our management staff, the project manager and general superintendent for marine work, both have over 20 years each in the marine industry. Training includes: ACOE - CQCM Certification, Hazwoper 40 Hours, OHSA 30 Hour, MSHA (Mine Safety) plus Drug Free Workplace Compliance Training. The owner also has experience in his earlier years as a merchant marine. Several of the site superintendents have 15-20 years experience in marine work and dredging operations.

The typical dredge project for our company is mechanically dredging with open-lake disposal utilizing dump scows. The larger dredge unit would include the Crow spud barge with either the Bucyrus-Erie 88B crane or Cat 375 excavator depending on material consistency. For open-lake disposal, we would utilize our larger dump scows (two at 550 CY and one at 500 CY). For upland CDF disposal, we would utilize an unloading crane, for example, a Manitowoc 3900 Vicon and off-road articulated dump trucks in addition to whatever disposal maintenance equipment that would be required. Either the upland disposal or lake dump scenario would achieve production of 1,800-2,000 CY per ten hour shift.

In smaller channels and harbors, especially in dense sand situations we would make use of a spud barge TNT or Derrick II with either a 42 ton rated Bucyrus-Erie 38B crane or our 3.5 CY rated Koehring 666 excavator. This operation could also be upland disposal or in-lake disposal utilizing the 300-350 CY dump scows.

Marine History Survey control work is completed in-house by a registered land surveyor and information is generated by utilizing the Hypak control system. We have frequent sounding checks on our projects which enables us to retrieve production units for cost analysis plus the QA/QC needed to keep projects running smoothly.

The equipment utilized on our dredge projects are well maintained and inspected. The tugboats have updated Coast Guard inspections, captains are licensed by the Coast Guard, spud barges (larger) along with the listed deck barges are current with ABS Certifications. Cable / crawler cranes utilized have also been certified.
