SPED PPD Advisory Committee members are exclusively drawn from pipers certified to Professional Piping Designer (PPD) Level IV. The charter of this committee is to review the PPD program content and advise SPED as to content, direction and qualifications. Members of this committee will be given extraordinary access to PPD notes, questions, glossaries and other material used in PPD training and assessment. They will be asked for feedback, comment, contributed material and other guidance for the PPD Certification program.


The SPED PPD Certification program has developed since 2003 into a robust program that has certified over 450 piping designers and engineers worldwide. The program adds about 150 pipers per year.

Level I emphasizes piping layout. Level III emphasizes equipment placement, spacing and orientation. Levels I and III require an exam be passed. The test banks for Levels I and III have about 450 and 1000 questions, respectively.

Levels II, III and IV require 4, 8 and 20 years of approved experience.

Despite this success, questions frequently arise:


Are the questions and content correct? For example, API standards recently called for straight runs before pump suction nozzles and the test bank did not reflect this until 2009.

Are 100 questions sufficient to test for 20 topics? Would 150 or 200 be better?

Should tests be developed for Level II and IV? Level II is supposed to reflect awareness of task information requirements and project procedures. Level IV is competence to estimate and execute full-scope piping projects.

Should the PPD program be specialized? Some would prefer specialized testing for land plants, offshore, power plants, waste water, etc.

Can we show more installed examples? With today’s level of security, it is impossible to tour modern plants, snapping pictures. 

What are the most missed skills in pipers? Over the years, SPED has added content to address known workforce weaknesses.

The PPD Advisory Council should help address these questions.

Who can belong: The members of the PPDAC are to be exclusively drawn from PPD Level IV Certified pipers.

Proposed benefits to participants: PPDAC members will be given access to notes, glossaries and selected test banks for review purposes.

Member Responsibilities: PPDAC members will be asked to review and comment on PPD Certification program content and contribute helpful information to enhance the program. A non-disclosure agreement is required. SPED agrees to be selective and respectful of member’s time.

Hassan Ahmed Hawam

I am a seasoned professional design and technical manager for many mega infrastructure, and
industrial projects, with over 28 years of diverse experience encompassing design,
construction, and operations including technical and procurement. My expertise spans various
knowledge areas, including process, mechanical and piping, and plant layout design, in
addition to construction and operation activities.
I worked in different projects fields including water & wastewater treatment plants, pumping
stations, water pipelines, chilled water pipelines, gas turbine power plants, food processing
units (edible oils and rice milling & silos), hygienic food storage facilities.
Throughout my career, I have actively contributed to significant projects with reputable
organizations such as Metito in UAE, Wetico in KSA, Kharafi National in Kwait, Aljaber
Engineering in Qatar and Horse Engineering Works in Egypt.
I have a master degree in fluid mechanics and as a licensed professional mechanical engineer
from Washington state, PMP certified, certified lead piping designer, and certified RO
specialist, I bring a comprehensive skill set that combines academic knowledge with practical

William Beazley

I enjoy applying my diversified experience and knowledge in engineering, management and human resource development to challenging problems in piping engineering and design, project execution, work process improvement and staff credentialing. I am inspired more by the specifics of contract fulfillment, commercial need, maintaining progress visibility and challenges of matching skills to task, than the exact nature of problems to solve. If engineering wasn't fun, I would have chosen other things to do.

Clarence Wynter

Clarence has over 35 years’ experience as an industrial designer, piping squad leader, Project Management, and field technical support, including 30 years of piping drafting and design. 

Clarence spent 5 years as an Evaluator for the Society of Piping Engineers and Designers (SPED) PPD programs and has delivered various presentations to technical writeups on site safety and technical support in the BIC magazine in Huston Texas.

A supporter of Society of Piping Engineers and Designers (SPED) since 2010, Clarence has been instrumental in supporting SPED Calgary as a supporting arm for piping designers. Due to the industry downturn. He aims to continue supporting his fellow pipers to generate a narrative to support the junior and intermediate pipers by having conversations on zoom forums sharing experience piping designers knowledge promoting SPED and SPED certification programs giving strength to the craft supporting designers throughout the Calgary and Edmonton markets.

Aligning SPED international communities collaborating with SPED Chapters broadening its reach in the Global market highlighting the integrity meeting industries standards.
