Call for Presentations: 2020 Multi-Agency Craft Conference (MACC)
Submission Deadline: April 17, 2020
The Multi-Agency Craft Conference (MACC) 2020 technical committee is seeking papers for inclusion in the MACC 2020 program.
MACC is an open forum for the exchange of operational and technical information on small boats and craft conducted between Government
agencies, Universities, Corporations (large and small) and the entire maritime community.
Recognizing the popularity of the multi-track technical program from 2018, MACC will again be offering three technical tracks:
•Boats and Craft Technical Track
•Launch and Recovery Technical Track
•Planing Hull Simulation Grand Challenge Technical Track
Since its founding in 1998, the Multi-Agency Craft Conference (MACC) has served as a primary venue for leveraging knowledge and lessons-learned across
multiple Government agencies that develop, procure, or operate small boats and craft. Information on new technologies and new product offerings as well as
information on Army and Navy service craft, Navy and Coast Guard patrol boats, Navy and USMC expeditionary craft, and Naval Special Warfare craft are highlighted in
chaired technical presentations, vendor and agency displays, and in-water demonstrations.
Since its founding in 2005, the Launch & Recovery (L&R) Symposium, encompassed within MACC since 2018, addresses the launch, recovery, and operations of manned and unmanned
vehicles from marine platforms. Manned and unmanned vehicles include helicopters, rotorcraft, fixed-wing aircraft, RHIBs, high-speed craft, tenders, UAV, USV, UUV, and
many more. Marine platforms include naval, coast guard, passenger, and commercial ships, as well as offshore platforms and other vessels. The scope of L&R includes the
launch and recovery systems, the host marine platforms, and the vehicles themselves-all of which are evolving at a rapid pace.
MACC 2020 will be host to the 2nd Planing Hull Simulation Grand Challenge. The objective of the grand challenge is to explore the current state of the art for numerical
simulation of planing hulls. ASNE is looking for participants with a variety of simulation tools from potential flow to direct numerical simulation.

- Vessel design
For the MACC 2020 Launch and Recovery track, we encourage new and returning participants to present their operational experience, technological developments and current
research. In addition, papers related to new concepts or processes intended to improve mission effectiveness, improve safety, reduce total ownership costs and meet new or
existing regulations are encouraged. These submissions are welcome from all segments of the international marine community including but not limited to governmental naval,
coast guard, environmental and natural resource management agencies; commercial shipping, construction and salvage operators; the offshore energy industry; and designers and
manufacturers who support these segments.
Simulation Grand Challenge Technical Track
For MACC 2020, the aim of the second Simulation Grand Challenge is to simulate the Generic Prismatic Planing Hull (GPPH) in waves. The GPPH was designed as a publicly
releasable hull to facilitate distribution to government, contractors, and universities. The prismatic hull design was chosen to be representative of typical combatant
craft while minimizing geometric variables such as warp, rocker and curvature in the transverse and longitudinal directions. The model was tested extensively at the United
States Naval Academy and Naval Surface Warfare Center Carderock Division (NSWCCD) through a project sponsored by the Office of Naval Research.
Participants in the 2020 Challenge are asked to simulate the same hull as described in the 2018 Challenge. The model characteristics, experimental results, and the official IGES model from the 2018 simulation are available in the linked zip folder.
Additionally, the NSWC-Carderock report summarizing the test effort is
available here.
For 2020 the challenge consists of simulating this vessel in head seas regular waves of height 5.03 inches, period 2.11 seconds, and at a model speed of 17.5 knots. The experimental trial was run in a wave group of 10 regular waves beginning from a calm basin. Results to be reported out under the Challenge include mean, RMS, and mean of the peaks for the following parameters at steady state:
Pitch at the vessel center of gravity
Heave at the vessel center of gravity
Vertical acceleration (location to be specified)
Pressure (location to be specified)
Please indicate your interest in this challenge by completing the abstract submission form and describing the computational tool to be used.
