Ice harvesting

Ice Mining is the process of mining Ice Fields, commonly refered to as "Ice Belts". The Odyssey patch changed the ice belts from permanent system features into anomalies that can be detected with the ship's scanner sensor overlay. These Ice Belt anomalies spawn in systems that used to have the permanent ice belts. One ice belt spawns after down time, and then once the ice asteroids have all been mined, a new ice belt will spawn exactly 4 hours after the belt was exhausted. A typical belt spawn is 10-20 ice asteroids each with 50-200 units of ice.

The cubes can then be sold or refined into fuel for Player Owned Structures and Capital Ship Jump Drives.

Special modules are required for ice mining. Each cycle produces a single ice cube some 1,000m3 in size. As it is not possible to increase this yield, upgrading for more efficiency is achieved by reducing cycle times.

Advantages of Ice Mining

• Reduced attention required by the miner - this has changed with the Odyssey patch - cycle times have halved.
• Self-sufficiency in terms of POS fuels.
• Lower penalty for working without a hauler - longer cycle times mean fewer trips to the station.
• Fun factor of 4-hourly 'Ice Rush' when a belt spawns, as dozens of miners rush in to clear the belt.

Disadvantages of Ice Mining

• Reduced ISK yield compared to normal mining - this has changed with the Odyssey patch - ice income per are now comparable to other ores, but the number of hours a day you can mine ice is less than rock ores due to the 4 hour respawn time.
• Smaller demand for ice products - this is also changing post-Odyssey, as CCP have stated that supply will be reduced to 80% of demand, so prices should rise.
• Increased chances of suicide ganks - this is changing now Odyssey patch has made scripted bot ice mining more difficult with the ice anomalies random location. Also the competition in clearing ice belt has reduced the number of AFK miners.

Ice Asteroids

In Empire space, there are a few systems in each region that have an Ice Field. The nearest to Aldrat is Eygfe. More can be found on external map sources such as dotlan.

Whereas before the Odyssey patch, ice belts were huge with thousands of ice asteroids spread over hundreds of kilometres, the new ice belt anomalies are much smaller, typically 10-20 ice asteroids spread over 50km.

Ice Ore

There are 4 basic types of ice asteroid. These match the faction that controls local space. With perfect ice refine capability, 1 unit of each type will always produce:

• 50 Heavy Water
• 25 Liquid Ozone
• 1 Strontium Clathrates
• 300 of a faction-specific isotope, as follows:

	Amarr - Clear Icicle	Caldari - White Glaze	Gallente - Blue Ice	Minmatar - Glacial Mass
Isotope	Helium	Nitrogen	Oxygen	Hydrogen

Basic Ice Mining Requirements

Ice Harvesting modules can only fit on Mining Barges or Exhumers. As with normal ore mining, the Retriever is the recommended starting point:

Retriever

The following skills are the minimum skills required to pilot a Retriever.

• Astrogeology III
• Science IV
• Industry V
• Mining Barge III
• Mining IV

Ice Harvester

in addition, to harvest ice, the following skill is required.

• Ice Harvesting I

With these skills the miner can acquire 1 piece of ice, per Ice Harvester, every 300 seconds (5 minutes).

Improving Cycle Times

Skills

Further training in Ice Harvesting will decrease the cycle time by 5% per level to a maximum 25% reduction in cycle time. Minimum cycle is therefore 225 seconds.

Tech 2 Modules

With Ice Harvesting 5 it is possible to use the Ice Harvester II module. This has a base cycle time of 250 seconds reducing to 187.5 seconds with the skill bonus applied. Ship bonuses , depending on what barge/exhumer you are using, can also affect harvesting. (bonuses are noted further down)

Ice Harvesting Upgrades

(Using the Retriever as an example)

Cycle times can be reduced further using Ice Harvesting Upgrades. These work in the same way as Mining Laser Upgrades, but reduce the cycle time instead of increasing yield. A T1 upgrade provides a 5% bonus (10% CPU penalty) and a T2 upgrade provides a 9% bonus (12.5% penalty). To minimise cycle time the aim is to fill all low power slots with these modules for a combined cycle reduction of 27%. [Note: Training up Skills:Industry#Mining Upgrades|Mining Upgrades will reduce the penalties as well as allowing use of the T2 upgrade at a higher level.]

Personal experience: I found that when fitting my ship with the Ice Harvester Upgrade IIs I ran out of CPU with 3 active and was unable to fit the two T2 Ice Harvesters. The issue was resolved by using a cpu upgrade rig (there were leftover calibration points) and training higher levels of Electronics.

Rigs

Medium Ice Harvester Accelerator I results in a 12% reduction to the duration of ice harvester cycles. Calibration cost: 250

Ice Output
Due to the changes:

       Skiff 66% reduction in cycle time + 1% for every level of Exhumer
       Mackinaw  33% reduction in cycle time + 1% for every level of Exhumer
       Hulk 0% reduction in cycle time but + 4% for every level of Exhumer
      [NOTE: mining barges have the same ship bonuses minus the Exhumer bonus] 

Cargo Space

       The Mackinaw its the elite in cargo hold followed by the skiff leaving the
       Hulk trailing behind at last place. 

Survivability
While most ice mining is done in hisec, suicide gankers often see the AFK nature of ice miners as an advantage.

       The Skiff takes the far lead due to its bonuses in shield tank ability.

Price

       Most dedicated miners will own a Hulk for high-yield mining, so frequently the
       Mackinaw is bought as a second ship dedicated to solo mining due to the large
       Ore hold.
       The market for both change depending on the demand or availablity, due to this
       reason the price cant be set as a guide to what ship is the cheapest and most 
       cost effective.
       looking at you local market and comparing the price with your needs will
       have to be taken into account to see what is the best for you.

The big question – Is Ice mining actually for me?

Yet again another question without a correct answer.

There are many reasons for and against Ice Mining, but there are some important facts that need to be said. Ice has a limited use compared to asteroids. Minerals from asteroids are used throughout eve, basically everything out there is made out of minerals where as ice products are only used in Player Owned Structures (POS) and certain ships with jump drive capability.

The final big issue is well, that ice is big! Just one block takes up 1000m3 of space. So an unmodified Hulk can only fit a low amount, not much really. Many professional ice miners will have a second account to act as a hauler to move the ice and leave the miner in place, be in a fleet or use the ore hold god called the Mackinaw.

Perfect Ice Mining Requirements

Mackinaw skills:

• Exhumers V
• Spaceship Command IV
• Industry V
• Astrogeology V
• Science IV
• Mining IV
• Mining Barge V

Ice Harvester II module:

• Ice Harvesting V

Ice Mining Upgrades

This skill set will result in a reduction of cycle time on your lasers. Modules, such as the Ice Harvester Upgrade can further decrease the cycle time. Implants, such as the 'Yeti' series can even further decrease this time. If possible, use a fleet booster such as an Orca, with boosts to decrease cycle time. Remember the yield boosters are useless, so the only boosts you can do in relation to Ice mining are time decreases.

== MAX Pilot & MAX Fleet == (need to update post Odyssey - base cycle times halved) (This results in a cycle time of 101 seconds for 2 blocks.)

Best Pilot (This results in a cycle time of 150 seconds for 2 blocks.)

• Ship: Mackinaw
  • Above Skills
  • Implant: Slot 10 - Yeti 5 (The Yeti 5 only improves cycle time by 5 seconds from the MAX of 101 to 106; so likely not worth the price.)
  • High Slot: 2 Ice Harvester II (The ORE does not help reduce cycle time, only CPU; so likely not worth the price.)
  • Low Slot: 3 Ice Harvester Upgrade II (The Ingenii does not help reduce cycle time, only CPU; so likely not worth the price.)
  • Rig Slot: 1 Medium Ice Harvester Accelerator I (There is no II at the moment.)

Best Booster (This results in a 32.3% reduction in Activation Time.)

• Ship: Orca
  • Skills:
    • Mining Director V
    • Warfare Link Specialist V
    • Industrial Command Ships V
  • Implant: Slot 10 - Mining Foreman Mindlink
  • High Slot: Mining Foreman Link - Laser Optimization II
