2021 IMT TTX

Witt O'Brien's will conduct a virtual Annual Incident Management Team Tabletop Exercise (IMT TTX)* in Houston for 2021. This challenging exercise will test the interaction, communication, and problem solving between the Incident Commander, Federal and State On-Scene Coordinators, and Incident Management Team (IMT) members, including the USCG, State Agencies, OSROs, SMFFs, the vessel operator’s representative, and other stakeholders in the critical stages of a vessel casualty.

NOTE: Due to the ongoing COVID-19 health crisis in the US and globally, we do not anticipate in person attendance for this event. Similarly, we continue to put all plans for our regular one-day IMT TTX seminars around the world on hold at this time.

As it is likely that current travel restrictions will remain for much of the year, we once again intend to develop an e-Learning course to allow each plan holder to participate in the seminar and satisfy compliance for 2021. It is anticipated that the 2021 IMT TTX e-learning course will be available mid-year 2021. More information will be posted here and distributed via circular as soon as registration for the 2021 IMT TTX is available. For any concerns or questions regarding IMT TTX compliance, please contact us at

The 2021 e-Learning course will cover the virtual IMT TTX carried out in Houston as well as expand upon content shared from the 2020 exercise in California. Separately, we will be conducting a series of 90-minute webinars throughout the year to provide “Regulatory Updates” as we did in 2020. Our last such webinar was held on December 10, 2020 and the replay is available here. We will announce via circular a schedule of dates for our webinars in due course which will also be posted here.


The annual IMT TTX is an important element in our ongoing “Partnership in Compliance” program. As required by USCG’s “Preparedness for Response Exercise Program (PREP) Guidelines”, each Vessel Response Plan Holder must test their plan by conducting an exercise with their incident management team annually. The State of California also requires Plan Holders to conduct an annual IMT TTX.

As your designated IMT, Witt O'Brien's designs, conducts, evaluates, and reports these exercises on your behalf to ensure compliance.

: The 2016 PREP Guidelines now require plan holders to participate in a Salvage and Marine Firefighting Table Top Exercises (SMFF TTX). We have coordinated with the SMFF service providers to integrate these requirements into our IMT TTX event to provide one event that will satisfy all requirements. Those who attend one of our IMT TTX events or complete the e-learning course will be issued certificates documenting participation in a combined exercise which also satisfies compliance with the SMFF TTX for 2021.

  • At least one representative for each plan (VRP) holder must attend one of the exercise venues, or complete the e-learning course.
  • As always, participation is unlimited.

To help meet our continuing commitment to conservation and the environment, we have again "gone green” for the 2020 IMT TTX Program. We will make handouts and presentations available on VesselProTM to download, print (as needed) and bring to the IMT TTX. This will not only save trees, but it will help minimize the carbon footprint of our IMT TTX program. Please contact us at for any VesselProTM access issues.


This event provides a unique opportunity to observe the largest and most experienced full time and contracted network of professional responders to all hazards and responses in the US spanning the last three decades.

Our team has hands-on experience in strategic and tactical decision making and have managed or provided technical support for some of the largest natural disasters and environmental emergencies, including the Deepwater Horizon and the Enbridge Pipeline oil spills as well Hurricanes Sandy, Katrina, Rita Ike and Gustav.

Witt O’Brien’s was the primary response manager for the most significant maritime incidents in recent history including the T/V Dubai Star, M/V COSCO Busan, M/T Athos I, and M/T Exxon Valdez.

We combine experience with state-of-the-art tools to be sure we stay ahead of paper work and reporting required in the federally mandated National Incident Management System (NIMS) Incident Command System (ICS).

Regardless of the size of the event, Witt O'Brien's leverages our extensive knowledge and relationships with USCG and other federal and state agencies to make sure your response operations are scaled to meet your needs, cost effective, and properly documented.
