TITLE: Stern Tube and Bulkhead Seals Major Overhaul (5YR)

(1) GOVERNMENT FURNISHED EQUIPMENT/MATERIAL Paragraph 4.1 states, “None”

Contractor notes upon soliciting OEM Wartsila for the parts identified in paragraphs 7.4.5, 7.6.2 and 7.6.6 the response was that they have a complete seal on order for the USS Emory Land due for delivery in June.

Contractor notes that the OEM was unable to confirm the MX however the MX9 Seal they were providing was intended for this job since this specification reflects an overhaul not replacement of the MX9 shaft seal.

Contractor believes the phase death with was intended to state deal with and appears tobe incomplete.

REQUEST FOR SPECIFICATION CLARIFICATION #34

SPECIFICATION ITEM NO.: 0021_A

PARAGRAPH / SECTION NO: 7.3 & 7.5,

TITLE: Clean Gas Free Tanks Voids and Cofferdams

Paragraph 7.3 states, “Provide a clean storage facility with a capacity of approximately 600,000 gal of fuel oil, 0 gal of JP-5 and 20,000 gal of lube oil.

Paragraph 7.5 states, “When directed by the MSCREP, return all fuel oil and lube oil to the vessel”.

Contractor notes the following, Due to strict environmental regulations in San Diego, CA, contractor repair facilities do not possess the regulatory permissions to store fuel onsite in the specified quantities identified in para 7.3. Consequently, no local fuel barge operators are available to store quantities listed within the specification.

With these environmental constraints, government vessels in San Diego use the Point Loma, CA Fuel Depot prior to entering a contractor repair facility and also following their departure from a repair facility for fuel offload and onload needs.

MSC can use Defense Logistics Agency SEA Card System as a low cost solution.

Contractor notes the following if required to propose fuel requirements in San Diego, IAW JFMM Volume VII, COMUSFLTFORCOMINST 4790.3 REV C CH-3, Paragraph 7.6.6 that states, “Fuel Off-Load Prior to an Industrial Availability. Surface force ships and aircraft carriers should enter any significant availability with a maximum fuel load of 15-20 percent unless there is an approved waiver to enter with more fuel onboard”.

600,000 gal of fuel oil is about approximately 190,266 gal above 20% of the vessels total fuel capacity based on the data provided in ENCLOSURE 2.2.1.

A San Diego contractor having to propose the additional costs to procure an out of town barge, including transit, tankermen, and storage services, adds undue cost and risk to submitting a competitive proposal, as well as, introducing schedule risk if awarded in San Diego CA.

QUESTION (1):

Due to onsite storage restrictions and prohibitive costs of out of town barges, Will MSC make fueling requirements, as outlined in the specification, for out of port San Diego bidders only and utilize the Point Loma CA. Fuel Depot?

If no, and required to propose fuel requirements in San Diego, QUESTION (2):

Will the vessel enter the contractor’s facility in accordance with the JFMM, a maximum fuel load of 15-20 percent, and will an Errata be issued revising paragraph 7.3 to reflect an approximate quantity (gallons)?

QUESTION (3):

To mitigate costs in San Diego CA, can Ship’s Force make arrangements with the government’s Point Loma CA Fuel Farm, to provide barges, hoses, and tankermen to offload/transfer and return/replenish ships fuel oil and lube oil?
