5.10 INCLINE EXPERIMENT & PLACING OF BALLAST

5.10.1 BALLAST

Due to changes in the vessel’s lightship and operational displacement, the Government requires up to 15,000-pounds of ballast to be installed in the aft steering gear compartment. Acceptable materials for ballast include lead plate, lead ingots/bars, and/or lead shot. The ballast shall be located to allow full access to all equipment, valves, switches and controls in the space, and maintenance access for inspection and painting to the bilges, bottom plating, and side shell plating. Ingress and egress from the space shall not be obstructed. The ballast shall be installed with the overall transverse center of gravity located on the vessel’s centerline. The ballast shall be installed in ballast boxes that are designed to keep the ballast from shifting. The ballast nor ballast boxes shall not be installed in the bilge with direct contact with the bottom plating.

The contractor shall develop drawings and details for the proposed ballast and installation. The drawings shall include details on the ballast location(s), type, quantity, ballast boxes/containment structures, and foundations. The drawings shall be submitted to USACE for review and approval prior to work commencing work. Once the drawings are approved, the contractor shall install the ballast boxes, but the ballast will not be loaded onboard until after the incline experiment is complete and the results evaluated. USACE will inform the contractor on the final quantity of ballast to install. All installed ballast shall be secured in the ballast boxes to prevent shifting during vessel operations. This is a government inspection point.

5.10.2 INCLINE EXPEREMENT

Due to changes in the vessel’s lightship displacement and the requirement addition of permanent ballast, an incline experiment is necessary to document the new lightship displacement and centers of gravity for the vessel. The contractor shall develop an incline experiment plan and submit to USACE for review and approval. The plan shall be prepared by a Registered Professional Engineer and submitted to USACE for review and approval. The incline experiment plan shall be submitted at least 45 days prior to the scheduled incline experiment. The incline experiment shall be in accordance with ASTM F1321. Following the completion of all work and the vessel refloated (without ballast), the contractor shall carryout an incline experiment to determine the lightship weight and centers of gravity. The experiment shall be directed by a Registered Professional Engineer and the results provided to USACE for review and approval. Following the approval of the incline experiment results, USACE will be responsible for updating all stability related documents with the new lightship characteristics and installed ballast. Within seven days of the incline experiment results approval, USACE will inform the contractor on the final quantity of ballast (not to exceed 15,000-pounds) to install. This is a government inspection point.
