About this file
This is a Statement of Work (SOW) for heavy lift crane rental services to execute the salvage and extraction of a partially sunken Navy Standard intermediate causeway Side Loadable Warping Tug (SLWT) barge at Naval Station Rota, Pier 4, Spain.
The Contractor shall provide certified crane operators, qualified riggers, support personnel, and specialized rigging equipment to perform a tandem lift extraction of the SLWT barge, which is currently secured to Pier 4 with its aft end submerged at approximately 35 feet of seawater. The vessel measures 85 feet long and 32 feet wide with a dry weight of 142,500 lbs; accounting for flooded compartments and retained water in 42 ballast tanks, the total wet weight is approximately 165,000 lbs. Key technical requirements include: providing certified mobile cranes capable of simultaneous tandem lifting; calculating and supplying all rigging gear (double 30-ton slings basketed to a 75-ton shackle at designated pick points) rated for the dynamic load; verifying working radius and pier load-bearing capacity using government-provided technical drawings; executing the tandem lift to extract the barge from the water; holding the suspended load above the waterline to allow gravity dewatering; and depositing the SLWT onto the concrete surface of Pier 4. The Contractor is responsible for all crane assets, rigging equipment, transport logistics, personnel travel, mobilization, lodging, per diem, and demobilization expenses on a firm-fixed-price basis. Deliverables include a detailed Rigging & Crane Lift Plan (due per RFQ) and daily activity logs during site operations (due by 08:00 AM following each operation day). Essential personnel include a Heavy Lift & Rigging Supervisor and Certified Crane Operators with tandem lift experience. The Contractor must satisfy military base security access requirements, submitting personnel background check documentation and vehicle registration at least ten business days prior to mobilization. The Government furnishes technical crane drawings and site access; all data, lift plans, reports, drawings, and photographs generated under the contract become the unlimited property of the United States Government.

STATEMENT OF WORK (SOW)
PROJECT: SIDE LOADABLE WARPING TUG (SLWT) LIFT OPERATION
LOCATION: NAVAL STATION (NAVSTA) ROTA, PIER 4
GENERAL INFORMATION
1.0 Scope of Work
The Contractor shall provide heavy lift crane rental services, certified crane operators, and specialized rigging equipment to execute a tandem lift extraction of a partially sunken Navy Standard intermediate causeway Side Loadable Warping Tug (SLWT) barge.
2.0 Background
The SLWT is currently secured to the end of Pier 4, at the Rota Naval Base, with the aft end underwater and resting on the sandy/silty seafloor at a depth of approximately 35 feet of seawater (fsw).
The vessel consists of a steel hull composed of three center modules (each 8 ft x 40 ft) and six end rake modules (each 8 ft x 20 ft), with a total length of 85 feet (approximately 26 meters) and a dry weight of 142,500 lbs (approximately 64.6 metric tons). See Attachment
2. A flooded pilot house and water retention in the 42 independent ballast tanks must be accounted for during the initial lift, which increases the total wet weight to approximately 165,000 lbs (80 short tons).
CONTRACTOR REQUIREMENTS
3.0 Technical Requirements/Tasks
The Contractor shall provide certified crane operators, qualified riggers, support personnel, certified mobile cranes and rigging gear. The Contractor shall perform the following specific tasks:
3.1 Crane Lift
Crane Mobilization: The Contractor shall provide cranes to Pier 4, NAVSTA Rota to lift the SLWT out of the water and onto pier 4. The SLWT estimated weight is 165,000 lbs (75,000 kgs) and should be placed on Pier 4 in designated area in Attachment 1 diagram.
• Rigging Accessories: The Contractor shall calculate, select, and supply all rigging gear rated to support the dynamic load of the barge, including the dry weight of 142,500 lbs plus the weight of retained water. The rigging gear shall include certified slings, spreader bars, and shackles. The rigging plan shall utilize double 30-ton slings basketed to a 75-ton shackle at designated crane pick points.
• Site Verification: The Contractor shall verify the working radius and pier load-bearing capacity limitations using the technical crane drawings provided by NAVFAC to ensure safe positioning.
3.2 Tandem Lift Salvage Maneuver Execution
3.2.1 Course of Action - Tandem Lift and Gravity Dewatering
• Tandem Lift: The Contractor shall execute a simultaneous tandem lift using cranes to raise the SLWT barge from the water.
• Topside Dewatering Hold: The Contractor shall hold the suspended load at a safe elevation above the waterline to allow entrapped water to gravity drain from the hull and pilot house into the harbor.
Placement: Once the vessel is sufficiently drained and the load stabilizes within safe crane operating parameters, the Contractor shall pivot the cranes and deposit the SLWT barge onto the concrete surface of Pier 4.
4.0 Government Furnished
The Government will provide the following assets, information, and services to support the execution of this contract:
• Government-Furnished Information (GFI): Technical crane drawings outlining Pier 4 dimensions and the Navy Standard Intermediate Causeway Salvage CONOP document.
• Site Access: Escorted access to Pier 4 and the designated DRMO yard.
(Note: The Government will not provide cranes, lifting/rigging gear, transport vehicles, or crane operators. The Contractor shall furnish all operational machinery, crane assets, transport logistics, and personnel required for the lift and subsequent transport).
