Public Draft – SAWE TO-2 “Procedure for Developing and Maintaining Documents”

A proposal to revise SAWE Recommended Practice TO-2 “Procedure for Developing and Maintaining Documents” is now available for comment at the Standards and Practices Public Review site here: https://www.sawe.org/standards/public-review/

The draft review period ends on 18 April 2021.

Missiles and Space Committee Meeting Review

The Missiles and Space committee of Standards and Practices held its first meeting outside of the international conference of any recent memory. This meeting was open to all SAWE members with an interest in Missile and Space committee activities and despite the rather short notice, we were happy to end up with a very well attended session, including European attendees. There was primarily discussion of the Recommended Practices (RPs) that Missiles and Space controls: RP A-6, Coordinate Systems; RP 9 and RP 10 Weight and Balance Control and Forms for Guided Missiles; and RP-16, Mass Properties Measurement. But the main takeaway was that if you have questions, comments, inputs about any Recommended Practices or anything Standards & Practices is responsible for, an email to standards@sawe.org will get your concern forwarded to the right person.

More informative meeting minutes and charts can be found at GroupOffice in the folder projects2/Standards and Practices/IC – Missiles & Space/Other Meetings. The next quarterly Missiles and Space meeting is planned for Friday, May 21st.

Thanks again to all that attended

Preliminary Design Mass Properties Estimation Forum March 26, 2021

The SAWE is continuing its series of virtual, Zoom-based Mass Properties Forums with the fourth installment, “Preliminary Design Mass Properties Estimation”. This Forum topic was the most requested topic in a survey of SAWE membership and prior Forum attendees.

A panel of industry Subject Matter Experts will start the discussions by expounding on how they would approach deriving the initial mass properties upon presentation of an RFP, ultimately resulting in delivery of preliminary mass properties to their proposal customer. These mass properties would include Not-To-Exceed mass, a preliminary analysis of Center of Gravity bounds, and if applicable, initial estimation of Moments and Products of Inertia. Following these introductory remarks by the panel, the Forum will proceed to questions, comments, and further examples from the audience.

The Forum will be conducted on Friday March 26th, 2021, commencing at 9:00 AM MDT (11:00 AM EDT, 16:00 CET) and will run for 90 minutes.

Registration for this Forum will open on Monday, March 15th.

SAWE RP O-3 Generic Weighing Procedure for Assemblies and Modules in the Offshore Oil Industry has been published.

Weight Control of offshore installations is critical to ensure that any Assembly, Module or Topsides may be installed using the proposed method, with minimum hook-up, and that the overall design caters for the most severe operating criteria identified.  RP O-3 establishes the requirements for weighing Assemblies, Modules or a complete Topsides facility.  It presents methods for preparation before a weighing and reporting results after a weighing has been completed and establishes methods employed to determine the center of gravity from a weighing process.

I’d like to thank the Offshore committee for the hard work in getting this document ready for publishing.  A special thanks goes out to Dave Bennett for providing his leadership for this document with respect to being a major author and editor during the development process

Upcoming SAWE Workshop!

UPCOMING SAWE WORKSHOP: January 29th, 10:00 – 11:00 am CST

Do you feel there are “Mass Properties 101” basics that every Mass Properties engineer should be knowledgeable about regardless of industry?
The SAWE Mass Properties Engineer Certification Committee is hosting an exam question brainstorming workshop where you can help shape the questions included on an Associate-Level Certified Mass Properties Engineer exam.  This exam will be non-industry specific, and will be geared toward members who have either a Bachelor’s degree and 2 years of experience OR 5 years of applicable MPE experience.

The workshop will be virtual with breakout “rooms” for different Mass Properties topics.

Not only is this an opportunity to help shape the knowledge base required for future Certified Mass Properties Engineers, this is also an opportunity to get to know your mass properties colleagues in an interactive setting.

If you are unable to attend the workshop but still want to submit questions, please submit them to Anjie.L.Emmett@NASA.gov

Keep an eye out for emails and updated blog posts on how to sign up!


The facilitators will send out topics, an agenda, and materials on January 20th.

Persuading Leaders and Peers of the Value of Mass Properties

The SAWE has been holding virtual forums using Zoom since the Tech Fair on various mass properties topics.  We are now in the initial phases of creating the third on the series.  The topic will be Persuading Leaders and Peers of the Value of Mass Properties, which will be presented on Friday, January 15th.  Nominally, we are looking for the Forum to run for an hour and a half starting at 9:00 AM MST (11:00 AM EST).

This forum will be somewhat different than previous forums in the following way – rather than a Forum leader and a host for the meeting, there will be a forum host and a panel of mass properties experts, who have now moved on to other positions in their organizations. We have identified people who have moved up to group lead and then to higher management levels, people who have risen to lead mass properties groups, people who oversee mass properties, and people who have experienced both well run and poorly run mass properties organizations.  Each have a tale to tell.

What we envision is  supplying a short PowerPoint template for each panelist to use to expound on their “secret sauce” on how to enable a well functioning mass properties effort, and more importantly, what the overall value of having such an organization (which could even be a single person) is to their group, company, and nation.  Each panelist will have a short period of time (approximately 3-4 minutes) to present their case.  After all the panelists have spoken, we will open up the floor for our audience to comment, ask questions, and discuss what they have just witnessed.  Then there we will conduct a short wrap-up with the opportunity for discussions to continue off-line.

Be on the look out for more information as the details are finalized, but now is the time to get this on your calendar to make sure you are part of this great virtual forum!

Give us Your Best Engineering Joke!

One thing I think everyone can agree on:  it has been a heck of a year, and everyone could use a bit of comic relief. 

So, for the Winter 2021 issue of “Weight Engineering”, we will be featuring a selection of favorite engineering jokes from the membership!  Please send your submissions to me at nmarickovich@gmail.com.  Along with the funny stuff, please send your name, SAWE chapter, and (if you’d like) a picture of yourself and why you find the joke meaningful to you. 

Please get your submissions in by 1/10/21 to be considered.  You can type your joke up in an email or send an MS Word or PDF file.  And let’s keep it classy folks:  jokes considered racist, sexist, or otherwise offensive will not be published.  Should not be a problem from such a fine bunch of Mass Properties Professionals such as yourselves!  Jokes at management’s expense would be considered par for the course, naturally. 

Thank you for your continued support of the SAWE through these challenging times. 

Nick Marickovich, VP Publications
