QUESTION NO. 10

DEFINITE ITEM 52 – U/W Body, preserve 100%

QUESTION:

What is the current coating system that was applied on the Underwater Hull at the last preservation?

Tech Rep questioned this for pricing out compatible materials, if Option Items 24 or 25 are activated.

Schedule B reflects Items 23 and 24 as Option Items Schedule B reflects Item 52 as Definite Item Please confirm USCG intention to activate Item 52 as Definite. This would negate the need for Item 23 and 24.

RESPONSE:

Per the Spec REV-0, dated 27 Jan 2016, page 251, para 3.2.2.1 states the current coating system.

Item 52 is a Definite Item. If the contractor and cutter do the hull inspection and feel that Item 23 or 24 is the proper way to go then this will change.

GFE Item – Hydraulic Motor Item 17 of Table 1 Recurring Maintenance – calls to renew the Hydraulic motor with GFP.

Table 3 – addl maintenance requirements NOW has an item designated with X –Disassemble & Inspect Hydraulic Motor Other column calls for alignment –assume this is the GFP motor renewed in Item 17? Is this the only additional work required in para 3.2.3 – just the alignment?

QUESTION NO. 12

DEFINITE ITEM 46 – Strain Gauge Alignment, Check

QUESTION:

Intent states that strain gauge alignment is to be done.

Para 3.2.1 state strain gage alignment check Para 3.2.8 states measuring using strain gauge method Para 3.2.9 states conversion of strain gauge readings Para 3.3 calls out for Load Cell Measurement and subsequent para 3.3 detail the measurements.

Strain Gauge and Load Cell measurements are two different types of measurements and require different equipment/instruments.

Is the Load Cell section 3.3 intent to be done as strain gauge alignment or Load Cell? Are we to plan for strain gauge readings AND load cell readings?

RESPONSE:

Contractor will do both Strain Gauge and Load Cell Measurements

QUESTION NO. 13

DEFINITE ITEM 54 – Bow and Stern Thruster Motors, Clean and Inspect

QUESTION:

Item 54 Title states Clean and Inspect Intent – states inspect, recondition and Test in Place windings of each motor Notes 4.1 states the machines could be removed for cleaning which is quicker and more cost effective in a motor repair shop.

Notes 4.1 states that this should be performed under bow and Stern Thruster motors overhauls and not this work item.

There is no Bow and Stern Thruster Motor Overhaul in the spec. Can this be done via CFR to the CO requesting removal to shop for effective cleaning?

RESPONSE:

Item 19 – Thruster Units (Bow and Stern), Overhaul covers the mechanical side of both units. Item 54- Bow and Stern Thruster Motors, Clean and Inspect covers the electrical side of both units.
