Tank and Vessel Entry via Rope Access.

Think Access carries out safe entry into storage tanks, pressure vessels, silos and process vessels using IRATA rope access combined with full confined space entry procedures. We provide trained entry teams, atmospheric monitoring and standby rescue for maintenance, inspection and cleaning works inside enclosed industrial vessels.

What we do

Systematic risk management

Tank and vessel entry carries multiple hazards, oxygen deficiency, toxic atmospheres, engulfment, mechanical hazards and structural collapse risk. Our teams manage every one systematically, starting with a thorough pre-entry assessment and risk review before any person enters the space.

Permit & isolation

Every entry is conducted under a formal confined space entry permit. The space is positively isolated from all energy sources before anyone goes in, so the environment is made safe and controlled before work ever begins.

Continuous atmospheric monitoring

Atmospheres are tested before entry and monitored continuously throughout by a trained gas tester stationed at the entry point. Communication is maintained between entry personnel and the standby team at all times.

Full-interior rope access

Rope access lets our entry personnel reach any part of the vessel interior, vertical side walls, structural internals, agitator supports and nozzle connections, as well as the base. The inspection or maintenance scope isn’t limited to what can be seen from the manway, and works are carried out at any position within the space.

Why Think Access

Tank and vessel entry is high-hazard work that requires a team that is competent in both confined space and rope access techniques. Think Access trains and qualifies our teams to the required standard and never compromises on the procedural safeguards.

F.A.Q’s

We test for oxygen percentage (deficiency and enrichment), flammable gas/vapour as a percentage of LEL, hydrogen sulphide (H2S) and carbon monoxide (CO) as a minimum. Additional analytes are included where the process history of the vessel indicates specific risks.

Yes, subject to appropriate risk assessment and decontamination procedures. We assess the hazards specific to each vessel based on its process history and carry out any required purging, cleaning or inertisation before entry.
