Refurbishments

A refurbishment is a more comprehensive refit which allows for replacement of obsolete or undesired fittings as well as overhauling any original equipment that remains.  Since a ship can get by on overhauls through its entire career, a refurbishment is never mandatory.  However, a ship that is refurbished is likely to be more effective than a ship that is merely overhauled.

A refurbishment costs 20% of the original dollar cost of construction, plus the dollar and BP costs of new components described below.  Refurbishments take the greater of 2.5 months, or 25% of the ship's original minimum time of construction plus one month per 2 BP of new components added to the ship.

See below for a description of what can and can not be done in a refurbishment.  Note that "tonnage" refers to those in a Springstyle report's "Distribution of weights at normal displacement"

Armament and machinery

All deck mounts and casemates, and secondary turret/barbettes, can be moved, added or deleted; main battery turret/barbettes can be replaced by turret/barbettes of equal or smaller roller diameter or other components allowed during refurbishments.  Newer machinery can be installed, but the weight can not exceed the previous set of machinery. 

BP cost = (tonnage/1000); $ cost = twice the BP cost.

Armor and functional miscellaneous weight

New armor decks, external belts, and external bulges for torpedo defence (not "torpedo bulkheads") can be added.  Existing armor decks, external belts, or weapon armor can be replaced or removed (not increased).  Functional miscellaneous weight can be added at the expense of non-functional miscellaneous weight or savings from removed components.

BP cost = (tonnage/1000); $ cost is equal to BP cost.

Hull, fittings & equipment

The waterline may be raised or lowered by 10%.  The trim may be changed. 

No BP cost; $ cost is equal to (tonnage/5000)

Fuel, ammunition & stores; non-functional miscellaneous weight 

Types of fuel can partially or wholly changed, but overall bunkerage not increased.  Changes to number and size of main-battery shells in magazines, but overall weight not increased.  Non-functional miscellaneous weight can be increased or decreased. 

No BP cost; $ cost is (tonnage/2000).
