Naval Base

Naval Bases provide bonuses to a Clan and its members, depending on which structures the Clan has built. There are a variety of structures available, including options for increasing the experience gains in ships of each nation, reducing the service costs of specific ship classes, and providing a discount on purchase costs of specific ship tiers. Each of these structures is purchased using Oil.

Oil

Players in a Clan can earn Oil, a Clan-specific resource to spend on building structures that improve the clan Naval Base and which provide bonuses to Clan members. While Wargaming will also occasionally offer in-game missions that reward Oil, it is earned regularly through two primary methods:

•  Each Container opened by a Clan member will add 10 Oil () to the Clan's stockpile. This bonus does not have a daily limit, and applies to regular Containers, Supercontainers, and any special Containers earned or purchased from the Premium Shop.
•  Each victory in Clan Battles will add 30 Oil () to the Clan's stockpile. The maximum that can be earned is 90 Oil () per member per day.

Players in a clan pool their Oil () to build Structures that benefit all clan members.

Structures

While any member can view the list of structures and their bonuses, only clan members given the role of "Builder" can build structures. Ten (10) types of structures are ultimately planned, with five (5) available in the first version. Each structure type modifies one in-game parameter. Structures are marked with special flags in order to indicate which ship type a certain structure type affects. The Clan's "Builder" opens flags by spending Oil. Opened flags make the structure's features available for the group of ships indicated on the flag, and a structure's current flags are indicated on its icon.

Headquarters

Headquarters facilities allow a Clan to grow beyond the base cap of 30 members.

Shipyard

Shipyard facilities decrease the credit cost of ships of a particular tier by 10% for Clan members. Any discounts on purchasing a ship will also apply to their sale; if a player buys and then sells the same ship while the 10% bonus is active, they will save 5% of the initial cost of the ship. If any other discount is active when the bonus is, they are not added together, but the larger one applies.

Building	Oil cost	Tier
Tier V Boathouse	50	Tier V
Tier VI Boathouse	200	Tier VI
Tier VII Boathouse	1,000	Tier VII
Tier VIII Boathouse	5,000	Tier VIII

Future discounts for Tier IX-X ships are planned, but are not available in the current iteration.
