Do you have what it takes to run an aircraft carrier’s propulsion plant? Find out in Explore Intrepid: Engineering, an immersive and highly detailed recreation of USS Intrepid’s navigation bridge, forward engine room and number 2 fire room. Learn how to steer the ship, run the engines, fuel the boilers and more. - In Story mode, the ship’s crew will guide you through the process of increasing speed as Intrepid races to recover the Gemini 3 space capsule in 1965. - In Explore mode, navigate the engineering spaces at your own pace. Earn new Navy ranks by completing interactive job trainings and opening popups with historic images, firsthand accounts from former crew members, and more. The aircraft carrier USS Intrepid served the United States Navy from 1943 to 1974. Massive boilers supplied steam to turbine engines that took Intrepid from the Arctic Circle to the South Pacific. The hard-working crew in the Engineering Department controlled and directed the high-pressure superheated steam. They also maintained the ship’s engines, boilers and miles of pipes and valves. Accessibility: - Screen-reader friendly with accessible navigation controls. - Audio descriptions of the modeled environment. - Captioning for all dialogue, sound effects, and ambient sound. - Adjust brightness, contrast, volume levels and more in the settings menu To learn more, visit intrepidmuseum.org or visit the Intrepid Museum in New York City.

Engine Room Simulator - ERS is a high-fidelity marine engineering training simulator for marine cadets, marine students, seafarers, and seamen who want to practice shipboard engine-room procedures with professional precision - anytime, anywhere, on mobile. Step into a realistic engine room and learn how a ship's machinery comes to life. From PPE safety training to generator synchronization to full voyage simulation, ERS turns complex marine engineering operations into repeatable, hands-on practice and onboard familiarization. MARITIME TRAINING, STEP BY STEP Work through guided engine room training modules with clear procedures, on-screen guidance, and instant feedback. This interactive training simulator builds from the fundamentals to full-plant operation - ideal for maritime education, competency training, and seafarer training. Practice the core shipboard systems: - PPE safety training and engine room safety induction - Emergency diesel generator cold-ship startup - Diesel Generator 1 and 2 starting - Diesel generator synchronization and paralleling - Seawater system and central seawater distribution - Freshwater system and cooling water system (LT/HT) - Lube oil system management - Fuel oil system pretreatment and service - Starting air system compressors and receivers - Boiler and steam plant operation - Marine diesel engine and engine startup training - Secure propulsion and propulsion control FULL VOYAGE SIMULATION Bring it all together in the Voyage Simulation hub - a connected engine room sandbox where shipboard systems and marine auxiliary systems operate at the same time. Perform system alignment training, manage the plant, handle electrical interlocks, and run the vessel like a real watchkeeping marine engineer. SAFETY FIRST, EVERY TIME Shipboard safety is built in. Complete your PPE and safety checks to unlock training modules, then gear up again every time you enter the engine room - just like real shipboard discipline. GUIDED AND ASSESSMENT LEARNING - Guided mode: a step-by-step narrator, on-screen pointers, and input gating help you learn each procedure correctly. - Assessment mode: an operations assessment with scoring and mistake tracking, unlocked once you complete the guided walkthrough. WHY ENGINE ROOM SIMULATOR - Built for marine cadets, marine engineering students, and working seafarers - Realistic P&ID-style shipboard system diagrams with pan and zoom - Authentic engine room operations, alarms, and trainer feedback - Premium, distraction-free full-screen interface - Practice marine engineering offline, on your own schedule - Repeatable drills and simulator practice to build muscle memory before you board Whether you are preparing for sea time, studying as a marine cadet, refreshing watchkeeping skills, or learning how a ship engine works, Engine Room Simulator - ERS is a complete marine simulator and ship systems simulator that gives you a safe, hands-on environment to learn, practice, and master engine room operations.
