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

• Coordination: The Contractor shall coordinate the lift timing with the Government Technical Point of Contact (POC). The Navy Dive Team (MDSU / MU8 / FDRMC) will attach the crane slings to the barge. Once both parties (contractor and Government technical POC) confirm attachment is secure, the Contractor shall execute the tandem lift.

• 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).

7.0 Contractor Personnel

The Contractor shall designate the following positions which are considered essential to the successful performance of the contract:

• Heavy Lift & Rigging Supervisor: Certified lift specialist with experience coordinating tandem mobile crane lifts, responsible for crane setup, rigging verification, and safe lift execution.

• Certified Crane Operators: Certified mobile crane operators with experience.

8.0 Security Requirements

The lift operation will take place entirely within NAVSTA Rota, a restricted Spanish-US joint military installation.

• All Contractor personnel and crane operators must satisfy military base access requirements.

• The Contractor shall submit complete base access requests, vehicle registration details, and background check documentation for all personnel at least ten (10) business days prior to the planned mobilization date.

• All machinery and vehicles mobilized to the base shall possess valid insurance, inspection certificates, and clear identification.

9.0 Data Rights

The United States Government shall have unlimited rights to all technical data, lift plans, reports, drawings, and photographs generated under this contract.
