Ice harvesting

Ice Mining is the process of mining Ice Fields, commonly refered to as "Ice Belts". 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 work for the miner.
• Ability be self-sufficient in terms of POS fuels.
• Lower penalty for working without a hauler - longer cycle times mean fewer trips to the station.
• Ice asteroids are huge - very small chance of actually having one pop.

Disadvantages of Ice Mining

• Reduced ISK yield compared to normal mining.
• Smaller demand for ice products
• Increased chances of suicide ganks.

Ice Asteroids

In Empire space, there are a few systems in each region that have an Ice Field. The nearest one to Aldrat is in Eygfe, and more can be found on maps such as dotlan.

Ice fields are very visually distinctive. Hundreds of kilometers long, each huge asteroid can contain well over 100,000 pieces of ice.

Ice Ore

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

• 50 Heavy Water
• 25 Liquid Ozone
• 1 Strontium Clathrates

as well as one faction-specific isotope:

	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 be fit on Mining Barges or Exhumers. As usual, the Retriever is the recommended starting point:

Retriever

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

Ice Harvester

The minimum additional skill requirement to use a basic Ice Harvester is;

• Ice Harvesting I

This skill set will result in 1 Piece of Ice per Ice Harvester with a base cycle time of 600 seconds or 10 minutes.

Improving Cycle Times

Skills

Continuing to learn the Ice Harvesting skill will decrease the cycle time by 5% per level for a grand total of 25% reduced cycle time which will give us a improved cycle time of 7.5 minutes.

Tech 2 Modules

The Ice Harvester II is available once Ice Harvesting 5 has been trained, which has a base cycle time of 500 seconds, and 375 seconds after the skill bonus is applied. Then the ship bonus depending on what barge/exhumer you are using. (bonuses are noted further down)

Ice Harvesting Upgrades

(Using the Retriever as the example)

We can reduce the cycle time even further by using Ice Harvesting Upgrades. These basically work the same as Mining Laser Upgrades,but the bonus reduces cycle time instead of increasing yield. A T1 upgrade gives a 5% bonus with a 10% CPU penalty, and a T2 upgrade gives a 9% bonus with 12.5% penalty. Obviously our ultimate aim is two fill all of the low power slots with these modules for a combined cycle reduction of 27%. [Note: Training up your Skills:Industry#Mining Upgrades|Mining Upgrades skill will reduce the penalty rate as well as allowing you to use the tech 2 at a higher level.]

As I found when fitting my ship with the Ice Harvester Upgrade II's (IHU II's) I ran out of CPU when i had 3 active and wasn't able to fit the two tech 2 Ice harvesters. I was able to fix this issue with a simple cpu upgrade rig useing the leftover 150 calibration points and training skill points in 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 abilitys.

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.

It is perhaps considered easier to ice mine, as the cycle times are significantly longer then asteroid mining modules, and ice asteroids are so massive, that it would take a large fleet of ships to mine all of the ice, as such it is very difficult for the ice asteroid to run out. Many miners will tell you the frustration at mining an asteroid with hardly next to nothing in it and loosing cycle time because they haven’t got the attention to focus on there scanners. This is perhaps where Ice Mining does come into its own, and many miners have been known to hit the "Ice Belt" while they are, for example, studying.

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.

• Ice Harvesting V

Ice Mining Upgrades

This skill set will result in a reduction of cycle time on your lasers.
