A-Frames: Functions & Applications

An A-frame is a distinctive framework that resembles the shape of the letter “A.” You’ll typically find it mounted on the deck of various types of vessels, from research vessels and offshore platforms to fishing boats and even some military ships. The structure is primarily made of robust steel beams, meticulously designed to withstand the harsh conditions of the open sea.

So, what exactly does an A-frame do?

  1. Lifting and Deployment: One of the primary purposes of an A-frame is to facilitate the lifting and deployment of heavy equipment and objects into the water. This could range from submersibles and remotely operated vehicles (ROVs) used in underwater exploration to large fishing nets and scientific instruments. The A-frame’s design provides a sturdy platform for controlled lowering and raising of these items, ensuring a smooth operation even in rough seas.
  2. Research and Exploration: Research vessels often use A-frames to launch and recover equipment for scientific investigations. Whether it’s collecting samples from the ocean floor or deploying sensors to measure environmental parameters, the A-frame’s robust structure ensures that delicate and valuable instruments can be handled with care.
  3. Subsea Construction: In the offshore industry, A-frames are utilized for subsea construction and maintenance. They enable the precise positioning of heavy structures, such as underwater pipelines, installation of oil rigs, and the assembly of various components required for offshore operations.
  4. Rescue and Recovery: A-frames are crucial in search and rescue operations, allowing swift deployment of lifeboats and rescue vessels. Their efficient design enables quick response times during emergencies, potentially saving lives in critical situations.
  5. Diving Operations: When divers are involved in maritime activities, A-frames can provide a secure platform for divers to enter and exit the water. These structures help in managing diving operations, ensuring the safety and comfort of divers during their missions.

Engineering Ingenuity and Design:

The engineering behind A-frames is a blend of strength, stability, and adaptability. These structures can be designed to withstand dynamic loads, intense vibrations, and the corrosive effects of saltwater. Their versatile design allows for customization based on the specific needs of the vessel and the tasks to be undertaken.

The next time you spot an A-frame on a vessel you’ll have a newfound appreciation for its significance. These seemingly simple structures are a testament to human ingenuity, contributing to safer, more productive, and possibly adventurous journeys across the vast oceans.

Space Perspective & Supreme Integrated Technology, Inc. Join Forces

Supreme Integrated Technology, Inc. (SIT), has joined forces with Space Perspective, the leading luxury space travel company in completing a new project. Starting in late 2024, Space Perspective Explorers will safely ascend to the edge of space in a climate-controlled, pressurized capsule, propelled by a SpaceBalloon rather than rockets, to experience the phenomenal beauty of Earth from space. The two companies are working together for retrieval operations of the capsule and its passengers at the conclusion of their space journey.

A large A-frame is needed to retrieve both the space capsule and the fast boat meeting the capsule from its specific landing location. Space Perspective was looking to retrofit an existing offshore service vessel (OSV) to accommodate this mission and needed to design a custom A-frame to accomplish the task. SIT was willing to assist with the design, starting from a “rough sketch idea” while working with Space Perspective to determine the specifications to make this system safer, including having it meet the recommended ship classification to ensure safety for space travelers.

“We looked at several vendors to support this critical need, and SIT was the clear choice thanks to their well-established reputation and deep engineering bench,” said Taber MacCallum, Founder and Co-CEO of Space Perspective.

The entire design required creativity from the SIT engineering team in collaboration with the Space Perspective engineers to ensure passenger safety and deliver a smooth, comfortable transport from capsule to the OSV. SIT’s scope of supply included:

  • A-frame structure
  • Luffing cylinders
  • Retrieval winch
  • Two tugger winches
  • Hydraulic power unit

SIT has built a valuable working relationship with Space Perspective, with respect for their mission to share the transformative power of space travel with as many people as possible. SIT earned this trust through quick responsiveness to a difficult application, as SIT is a small, 100% employee-ownership company with nimbleness to deliver a turnkey solution.

SIT’s engineering expertise transforms ideas into success for hydraulic or electric powered moveable structures. Using innovative methodologies, SIT gives customers a single-source solution for marine, civil, Jacking System, industrial, aerospace & military applications. SIT is part of EOHI, a 100% employee owned company based in Houston, Texas and also the parent of Hydraquip, Inc., GCC, and Elite Controls, Inc.
