In-service inspections are designed to evaluate a tank's structural integrity and detect any wear or defects that could compromise its safety. Philips Tank & Structure is qualified and equipped to inspect and repair storage tanks while they are in service.

API 653 In-Service Tank Inspection

In-service inspections typically take place every five years. For tanks in more corrosive service, inspections must be conducted at shorter intervals, based on the rate of deterioration and the remaining metal thickness.


Our authorized inspectors complete a thorough visual inspection of the tank's exterior surface. This includes checking for leaks, shell distortion, corrosion, uneven settlement, and coating failure. Internal or external floating roofs are checked for seal damage, seal fabric damage, and excessive seal gaps. 


Services we offer include:

  • IFR Seal Inspections

  • IFR Seal Repair

  • IFR Repair

  • Bracing or Bracket Installation or Removal

  • Varec Gauge Replacement

  • Fabric Overlay or Replacement​


The primary objective of in-service inspections is to ensure the safety of personnel and the environment. Regular inspections can prevent accidents, injuries, and environmental damage resulting from tank failure. By detecting defects early on, inspectors can recommend corrective actions that reduce the risk of tank failure, limit costly repairs, and reduce downtime.

Confined Space Rescue

For the safety of the tank inspection team, a confined space rescue team must be present during work inside the tank. If an individual is trapped or injured in a confined space, such as a storage tank, they must be removed as safely and quickly as possible.

Phillips Tank & Structure Rescue Team

The PTS Rescue Team is a highly trained and skilled group. The goal of the tank rescue team is to ensure employees are protected while working in hazardous conditions or in spaces with difficult access.


The Rescue Team is made up of the following positions:

  • Team Leader

  • Entry Attendant

  • Rescuer

  • Hauler

  • Bottle Watch

While these positions are set it is important to note that the size of the crew will always be dictated by the type of rescue and the environment of the rescue.


Rescue Team Training

The training of the PTS Rescue team is continuous. There is always room for improvement and gained experience when lives are on the line. At a minimum the following is the training for a PTS Rescue Team member:

  • 40hrs Confined Space Rescuer Training

  • Live Simulation Training at least every 12 months

  • CPR and Basic First Aid

  • Current Medical Clearance to Wear a Respirator

  • Certified Fit Test

  • Confined Space Entry

  • Respiratory Protection

  • Fall Protection

  • Hole Watch / Bottle Watch



Our confined space rescue program was developed alongside leading industry professionals. The PTS Construction Group, Safety Group, and Design Group worked together to establish a package of required documents that are used by the Rescue Team in every Rescue Situation. The package includes:

  • Confined Space Entry and Rescue Plan (Transmitted as a drawing)

  • Emergency Run Sheet

  • Confined Space Rescue Reference Sheet

  • Confined Space Entry Safe Work Plan

Each rescue situation is evaluated by the Rescue team and leader on site and documented accordingly.
