Answers to questions submitted by various vendors:

Item 205: Can you confirm that there will be 30 valves that need to be replaced with new valves and only three valves are going to be overhauled in accordance with the valve table? Are all of the 30 valves being replaced going to be bronze, monel trim, bolted bonnet style?

• • Answer: Exact oil should be dictated by the Service Representative performing the task.

Item 120: How many total tanks need to be open/closed and need lighting/ventilation for this item?

“load from the public water system.”

The specification does not provide a reference to identify the material grade and size of weak link to install. Request the government provide the information listed for estimating purposes.

Item 214 Stern Thruster Maintenance: The work item directs the contractor to “Conduct a complete inspection of thruster in accordance with manufacturer’s maintenance at this docking with strip, clean and repacking of both rotor shaft and steering shaft glands”. Please forward the section of the maintenance manual that describes the requirements of the “complete inspection of thruster in accordance with manufacturer’s maintenance” so that the contractor can correctly provide labor and material estimates. No maintenance manual available. OEM is Tees White Gills Thrusters, POC is Adam Robson at

Adam.robson@teescomponents.co.uk, he will quote VERHAAR OMEGA Service Representative attendance.

Item 214 Stern Thruster Maintenance: The work item directs the contractor to clean, polish and paint the stern thruster propeller. Is it the intent of this requirement to access the rotor through the inspection ports and inlet grating to complete the cleaning, polishing and painting of the rotor? Or does the customer expect the rotor to be removed from the vessel for this work? Propeller is to be cleaned and painted in place through the inlet and exhaust openings.

Item 216 Hull Repairs; Replace Steel in #3 Port SWB and CL Flume Tank: The customer previously indicated that repairs are to be limited to areas from Frame 35 to Frame 41. Is the contractor to price replacing steel, three (3) feet from centerline, port and starboard, and 4” aft of frame 35 to 4” forward of frame 41 to eliminate the cost of replacing steel past each bulkhead? If the ABS Surveyor indicates that steel replacement must go beyond these bulkheads, this will be the subject of a Change Order Request.

Agreed

Item 205 Sea Valves: The work item clearly describes the work to be complete to the sea valves listed.

The only place the strainers are mentioned is in the third paragraph of the statement of work. Please define the requirements to “place in first class seaworthy and serviceable condition”. Are the strainers to be removed? Internals preserved? Plug valves lapped and leak tested? Strainer baskets replaced or repaired? There is not a defined scope of work to estimate labor and materials for this portion of the work item. Contractor to issue CFR if repairs needed.

Item 203 Rudder Pintle Clearances: The customer has determined that the items listed in the work item are not onboard. The contractor requests that the work item be deleted or revised to include an inspection that is more in-line with the components installed onboard this vessel. See attached readings from 2020

Item 120 Safe for Entry and safe for Hot Work Certificates: Item 120 is an item to be priced in accordance with the supplied Vendor Price Sheet.

The work item contains two paragraphs that are contradictory in the view of this contractor.

(1) All additional costs and re-certification due to shifting the ship within the yard, ballasting or de-ballasting, growth work and/or additional ITEMS and sea trials departure/arrival shall be included in this

ITEM. How is the contractor to price additional costs of certification on growth work or new items at this time? Contractor to issue CFR if necessary.

(2) Since this item is to be included on the Vendor Pricing Sheet, it would seem that all costs for certification would be entered here. But the next paragraph indicates that “The Contractor shall include the cost for adherence to this ITEM within the individual ITEMS requiring any tank entry of hot work”.

Please indicate if ITEM 120 is to be priced on the Vendor Pricing sheet, or if the costs for adherence to this item are to be included in each individual item requiring hot work. Yes, Price #120 on Vendor

Pricing Sheet

Item 114 Provide Shore Power: The Vendor Pricing Sheet Provided does not include a line to enter the costs of installation of the meter and connections and disconnections to support the dry dock and trials.

Item 105 Office and Administrative Services: The work item requires (1) plain paper fax machine and (1) copier. Will an “all in one” machine that meets the requirements of both items be acceptable? All in one will be great.
