International School

for Inspectors of Petroleum

International School for Inspectors of Petroleum (ISIP), an affiliate company of Enercon Group, Inc., is an independently owned corporation specifically formed to provide certification, training and related consulting services to the petroleum and maritime industries. It is committed to excellence in petroleum measurement and operational safety with all of its programs founded on API, IP, ISO, IMO and other related industry standards.


Certification provides various benefits to the inspector and the user alike. Some examples include:

  • Provides an independent verification of surveyor's expertise & qualifications.
  • Confirmation of a surveyor's knowledge of basic terminal and safety requirements.
  • Recognizes the professionalism of the surveyor and his or her commitment to providing quality service.
  • Assures the surveyor's knowledge is kept current through a certification renewal process.
  • Complements ISO 9000 and ISM programs.

Current Certification and Review Program:

Frequently Asked Questions...


What is the purpose of the Certificate Issued?

The issuance of the certificate to qualified individuals is an independent attestation that the holder has been tested and found knowledgeable in the areas of Marine Cargo Inspection/Surveying as detailed in API MPMS Chapter 17 standards and has experience in those areas.


Who can get one?

To be eligible to take the basic ISIP certification exam, the candidate must have at least 365 days verifiable, active, employment as a petroleum inspector or in a related position and have completed a recognized training program. The candidate must then successfully complete a two-day written and practical exam with an 80% average.


How long does the Certification remain valid?

Each certification will be valid for three years after which it must be renewed.


Why the Limit on the Certificate's Validity?

The industry updates, changes and issues new standards and procedures for oil measurement and safety on a routine basis. API has a policy of reviewing standards every five years to re-validate, revise or remove them. A renewable certificate will assure the certified inspector remains current on the latest changes. Also, the renewal process assures the inspector has remained active in the field.


What is the Renewal Process?

A candidate must show verifiable experience, additional training and pass an appropriate exam relative to the certificate being renewed.


Will Certification Guarantee Good Cargo Surveys and Inspections?

Nothing can guarantee that. However, this certificate assures the surveyor/ inspector is experienced, trained, and has passed a comprehensive exam on marine cargo inspection and safety.


Will Certification Reduce Oil Losses?

It is a known fact that most oil "losses" are caused by human error. It is also documented throughout the industry that oil losses can be reduced by 40% or more if the movement is well monitored by qualified personnel. Therefore it is more likely that better trained, certified, personnel will help reduce oil cargo and bunker losses overall.


What is on the exam?

The exam consists of 5 parts. The first 4 sections contain 100 questions each and the 5th section is comprised of 5 practical problems and exercises. All material is based on current API and/or IP standards and the latest safety information found in ISGOTT.


How is this Different from the ISO 9000 Programs?

ISO 9000 programs offer certification to the participating companies whereas this program certifies the qualified individual inspector. Also, the ISO programs allow the company to be proficient in any standards they wish. This program is based on API - IP and ISGOTT standards and procedures.


Does the API Endorse Certification?

As a commercial issue, API does not endorse any private training programs. It does, however, encourage training and education. Further, API MPMS Chapters 17.1 and 17.2 specifically state that inspectors involved in custody transfer measurements must be properly trained in relative measurement, operations, and safety issues. This certification program is founded in these principles and is based on the latest API and ISGOTT standards and procedures.


Who developed the Certification Exams?

The exams used for the ISIP certification programs have been developed by well respected members of the petroleum and marine industries. They have been chairmen or active members of working groups that wrote the existing industry custody transfer standards.

In addition, ISIP's board of advisors is comprised of respected members of the marine industry and the educational profession.


What will Certification cost?

The fee for taking the two-day certification exam is cost-effective.


 Certification Exam 

The comprehensive written exam consists of two parts given during two days.


The first part contains 400 real-life questions dealing with measurement, ship/terminal operations, safety, and general industry practices and procedures, such as:

  • Application of Current Measurement Standards
  • Knowledge of Measurement Procedures and Industry Practices
  • Basic Dynamic and Static Measurement
  • Volumetric Calculations and Documentation
  • General Ship and Shore Safety Practices
  • All Other Applicable Measurement Procedures

The second part consists of five case problems dealing with practical aspects of cargo inspection as follows:

  • Knowledge of Applicable API/IP Standards
  • Finding Losses/Problems Using Voyage Analysis
  • Determining Cargo Onboard Using Deadweight Surveys
  • Calculation and Practical Application of the Vessel Experience Factor (VEF)
  • Practical Application of the Wedge Factor to Calculate Small Quantities on Vessels

All test questions are based entirely on the latest published editions of the relevant API/IP Manual of Petroleum Measurement Standards (MPMS) and the International Safety Guide for Oil Tankers and Terminals (ISGOTT). The overall passing grade is 80% while the minimum acceptable grade for the practical section is 90%. All general areas on the exam will be well covered during the three-day review program.
