PERFORMANCE WORK STATEMENT

PART 2 – DRYDOCKING

0001 DD-1 BERTHAGE, DRYDOCKING AND SERVICES. The contractor’s drydock must be within 1600 nautical miles from Misssissippi River Southwest Pass, see attachment J-20 for nautical miles chart.

The contractor must have drydock facility available on October 1, 2015 or the second week of October 2015.

The Contractor shall furnish pilot service and tugs service to safely escort/move the ship from entrance channel sea buoy closest to Contractor's facility to Contractor's drydock.

Thereafter, the Contractor shall provide these pilot and tugs services to move/escort the ship while the vessel is in his possession, including multiple (if applicable) moving/escorting the ship from contractor’s drydock to contractor’s wetberth or vice versa. Refer to Section F for details of delivery and return of the vessel. Delivery and return will be coordinated with the Contracting Officer Representative.

Upon receipt of the vessel, the Contractor shall drydock the vessel for such time that will be necessary to complete all underwater work included in these specifications. The time at wet-dock berthing or other prior to starting any work, shall not exceed five (5) calendar days prior to entering the drydock.

Prior to drydocking, the Contractor shall prepare a proposed blocking plan, utilizing the data on ASI Dwg. No. 07-00-01 Docking Plan, and submit the blocking plan to the Contracting Officer Representative for approval. The drydock shall be capable of handling the vessel, meeting the draft requirements listed below without the removal of fuel or water:

The following are the estimated ship’s draft at time of arrival and the drydock requirement:

The ship will arrive at the contractor drydock at the estimated draft of 21 feet Aft and 18 feet Forward.

The blocks in the drydock (graving or floating docks) must be minimum of five (5) feet high (Note: Blocks are less than 5 feet high shall not be accepted). With the Wheeler landed, the drydock (floating dock only) must have a minimum freeboard of 1 ft - 0 inch.

During drydocking and undocking process, there must be a minimum of one (1) foot clearance between the bottom of keel plate and the top of the blocks. Upon drydocking, all blocks shall be checked and wedged up for firm contact with the hull.

For safety reason, the drydock (graving or floating) must have a minimum of 10 ft clearance on each side of the ship from the side of the hull to the drydock innermost intrusion. In another words, drydock with an internal width clearance of less than 100 ft shall not be acceptable.

Drydock length must be longer than the overall length of the ship, which is 408 ft- 3 inch, so that there is no part of the ship, either bow or stern, extends pass the drydock and overhangs the water.

Important Note: Due to the scope of work in many line items in the hopper that require foreseeable extensive usage of crane services, it is a requirement that the contractor’s drydock must have two (2) working cranes during the entire contract.

During the drydocking and undocking procedures while the ship is in the contractor’s possession, the contractor shall provide the services of a pilot, tugboats and all line handlers (aboard and ashore) and all required lines. Note: During dock trials, the contractor shall provide the service of one (1) tugboat with a minimum of 4000 HP and extra mooring lines (see sections TR-1 and TR-2 for additional information).

DRYDOCK SUBMITTALS -- Unless specified otherwise, at least forty eight (48) hours prior to docking/undocking the vessel, submit to the Contracting Officer Representative the following:

Drydock certification submittal. Prior to award of the Contract, submit to the Contracting Officer certification for the drydock or tentative drydocks to be used to lift the vessel.

(2) American Bureau of Shipping (ABS)

(3) An independent registered Professional Engineer, who shall cover the inspection requirements of item (1) or (2) above.

The Inspection Certificate shall be within three (3) years if the age of the dock is less than ten (10) years old and within two

(2) years if the age of the dock is over ten (10) years old.

Note: Floating drydocks must be one integral unit. The Government will not allow the coupling of two rated docks to meet the load requirements of the vessel. Also, the contractor shall not use the drydock to perform other work(s) on other contracts except for the work specified (or related) in this contract while the ship is in the drydock.

Certification inclusions. Regardless of the type of certification provided, submit to the Contracting Officer Representative the information regarding the docking facility, as applicable:

(1) Drainage and dewatering systems

(2) Mooring systems for floating docks

(3) Fire protection services

(4) Fire alarm locations

(5) Emergency power

(6) Emergency ballast/dewatering pumps

(7) Structural Examination with Load per Foot Rating

(3) Has served under a dockmaster in an apprentice or assistant role during at least 10 dockings or undockings and has served as a dockmaster at the type of facility for which the individual is qualified during at least 5 dockings or undockings, of which one has been accomplished within the previous 6 months.

Immediately after drydocking, provide and install temporary scupper drains and sewage pumpout lines of suitable sizes from the drains and overboard discharge lines, as required to prevent water draining down the ship's sides. Leave temporary drain lines connected throughout drydock. Proceed to dispose of all mud and debris being removed from the following hopper areas:

longitudinal beams, transverse beams, bulkheads, discharge gratings, door seal areas, and hopper sloping hips in all hopper bins. All of the above areas shall be thoroughly cleaned and washed after removal of mud and debris. This shall be accomplished within five days of entering dry-dock. Also cut and remove all ropes, debris, rocks, and other trash, wherever located throughout hopper areas, including all trash deflectors (aft,frame 61), trash screens (fwd), and turtle catch cages (aft and fwd). Remove all drain lines after completion of drydock work. Also leave hoppers and hopper areas clean and leave dredge ready for undocking. The contractor shall be responsible to dispose of all sand and debris from the drydock floor. The Contractor shall be responsible for pumping all bilges, disposing of sewage treatment plant effluent and containing and/or removing and disposing any oil which may accumulate anywhere on the vessel, including the hoppers, during the course of the repair period.

INSPECTION POINT. Prior to undocking the vessel, a pre-undocking conference shall be held with representatives of the contractor, Government Inspectors, and ship’s crew in attendance. The plan for undocking shall be reviewed and agreed upon. The hazardous energy/lock out status of the ship’s equipment will be reviewed and updated at this time. A determination shall be made of what systems or equipment require tag out prior to undocking. The Contractor and a representative of the Contracting Officer will perform a joint pre-undocking inspection in accordance with the checklist provided in Section J, Attachment No. J-1, to ensure that the vessel is in all respects ready to be re-floated. The checklist shall be completed by the Contractor, verified by the Government Inspectors and submitted to the Contracting Officer Representative prior to the undocking. Undock the vessel, after all underwater work and the pre-undocking inspection have been completed.
