Full Scale ESH Testing
Spantech is the only Explosives Storehouse (ESH) proven in full scale explosive trials.
A comprehensive series of donor and receptor trials were conducted at Woomera in 1991 and 1992.
All trials were based on NATO standards conducted by defence forces from:
- Australia
- United Kingdom
- United States of America
Methods
The trials involved construction of a number of 13 metre wide Spantech ESH and one Spantech 23 metre wide ESH.
75,000 kgs NEQ of HD1.1 anti-tank mines were placed in donor buildings and wired for simultaneous detonation.
Receptor buildings were situated at minimal safety distances; 21metres side to side (D3) and 34 metres front to back (D4).
Tests included:
 13m ESH:
- receptor to 75,000 kgs NEQ of HD1.1 contained blast
- receptor to 75,000 kgs NEQ of HD1.1 open air blast
- donor containing 75,000 kgs NEQ of HD1.1
- donor containing 1 pallet HD1.2
- donor containing 16 pallets HD 1.2
- donor containing 160 pallets HD 1.2
23m ESH:
- receptor to 75,000 kgs NEQ of HD1.1 contained blast

Inside the 13m ESH 75,000 kgs NEQ of HD1.1 are wired for instantaneous detonation
Three Spantech 13m ESH survived this 75,000 kgs blast during the first test

| Results
The Spantech design exceeded expectations in all key areas
- Safety
- Cost
- Construction time
Spantech donor buildings outperformed tested alternatives while Spantech receptor buildings sustained little or no damage.
One Spantech 13m ESH survived three 75,000 kgs blasts.
In all cases the structures exceeded NATO standards.
The Spantech ESH is now defined in NATO standards and specified by a number of defence agencies. |
