When necessary to schedule a test or inspection after the normal day shift or on a weekend, the USGS Technical Representative shall be notified of the test or inspection at least four hours before the end of the last preceding regular work shift.

Whenever a “hose test” is specified, conduct the test by directing a 50-psig stream of water from a 1-1/2 inch fire hose through an all-purpose nozzle at a distance of not more than 10 feet from the surface being tested. Direct the stream of water in a manner most likely to disclose a leak and inspect the opposite side of the surface for leaks.

Whenever an “air test” is required, conduct the test by sealing all vents and applying 2 psig air pressure to the specified tank or compartment. After the 2 psig pressure is attained, disconnect the air supply and monitor the pressure in the tank or compartment with a calibrated pressure gage for 10 minutes. If the pressure drops below 1.9 psig during the 10- minute period, increase the pressure to 2 psig and inspect for leaks by applying soapy water to all new welds, and to all manhole covers of the tank or compartment. After the test, insure that all vents are unsealed.

Garbage Removal The Contractor shall provide a dumpster for trash and food waste generated by ship’s crew. All debris and garbage generated by the Contractor personnel shall be removed once per day. Food or eating on the vessel by the Contractor’s crew is not allowed.

Smoking and the use of e-cigarettes is not permitted onboard the vessel.

Fuel Oil and Lube Oil Offloading Whenever the Contractor is required to or elects to offload fuel oil or lube oil from the ship, the oil shall be pumped to and stored in clean moisture-free storage tanks. Meter the oils with a calibrated meter during offloading and during return. Take test samples during offloading and during return and have the test samples analyzed by a lab for water and impurities to verify that the oils were not contaminated while in the Contractor’s possession. Provide copies of lab reports to the USGS Technical Representative.

After all work which necessitated the oil’s removal has been completed, return the oil to the ship. In lieu of storing the oil, the Contractor may accept title and responsibility for disposal of the oil and provide an equal amount of new clean oil, same as that removed. Test samples are required, even if this option is exercised by the Contractor.

Disposal of Water Whenever work requires that equipment, machinery, piping, or tanks be drained of water, the Contractor shall be responsible for draining and proper disposal of the water. The Contractor shall not drain any fluids into the bilge. If water spills into the ship’s bilges, the Contractor shall pump all water from the applicable bilges into dockside tanks and properly dispose of the water, including the water that existed prior to and the water that accumulates between the time the equipment, machinery, piping or tanks were drained and the time the bilges have been pumped dry by the Contractor.

Confined Space Entry As required by the Work Item, the Contractor shall open and gas-free confined spaces prior to entry. All tanks and void spaces shall be cleaned prior to the commencement of hot work, decking removal, and piping work. Each tank to be entered shall be at a minimum gas-free certified “Safe for Personnel, Not Safe for Hotwork” prior to entry. All tanks in way of hot work shall be gas-free certified “Safe for Personnel, Safe for Hot Work” prior to the start of hot work. Each gas-free certificate shall be maintained for the full duration of the work. Gas Free certificates shall only be issued by a certified “Marine Chemist” or “Competent Person” as defined by 29 CFR Part 1915 – Occupational Safety and Health Standards for Shipyard Employment.

HAULING, BLOCKING AND LAUNCHING

Hauling, Blocking and Launching The contractor shall dock the vessel for the underwater hull inspection, sandblasting, painting, and repairs of the underwater hull as well as the installation and/or modification of machinery and piping systems connected to the underwater hull. Contractor shall re-float the vessel in good order upon completion of all specified underwater repairs, cleaning, sandblasting, and painting. The USGS Technical Representative shall be present when undocking/launching vessel.

The Contractor is responsible for the safe hauling, blocking and launching of the ship at a time and manner as agreed upon by the Contractor and the USGS Technical Representative. A launching plan including hauling/launching calculations must be prepared and presented to the USGS Technical Representative for review and approval in advance.

The vessel shall be supported on keel, bilge and chine blocks and shores fitted to ensure the vessel and personnel safety and security. The contractor shall not use shipboard deck machinery to control or winch the vessel into position, but may use appropriate mooring appliances or attachment points on the vessel to secure and control the vessel during docking and undocking. The Contractors will not dry dock the vessel without the Master and/or the USGS Technical Representative present to observe and approve the process of docking or undocking the vessel.

The Contractor shall use divers to monitor the block/strap arrangement and clearances during docking and undocking. The diver shall verify that the vessel is properly aligned on the blocks before the block/straps are brought into contact with the vessel.

The blocking shall be of sufficient height to allow for adequate clearance to perform work on the propellers and rudders, to perform maintenance on the transducer wells near the waist on the port and starboard side near the keel, bottom preparation and coating, and as necessary to conduct ultrasonic testing, steel replacement, installation and maintenance of transducers, and any other repairs that may be required on the bottom of the vessel.

All costs associated with and incidental to docking and undocking, including dock preparation and clean up shall be included in this quote and there shall not be additional labor or material charges.

Haul Out Planning Arrival Condition

The USGS Technical Representative shall advise the Contractor of the actual vessel tank and draft readings when the vessel arrives and will discuss with the Contractor any liquid loading changes necessary. The contractor shall use the Full Load Condition, for the purposes of performing pre-haul out calculations.

Drydock Stability If the Contractor plans to use a floating dock, graving dock or marine railway to haul out the vessel, the Contractor shall submit stability calculations for the vessel and drydock (when applicable) using the Full Load vessel condition unless otherwise agreed upon by the USGS Technical Representative. Calculations shall be provided prior to the dry docking of the vessel.
