CES Trainer vs Engine Room Simulator

CES Trainer helps seafarers prepare for the CES (Crew Evaluation System) test. Practise CES-format questions for your department and level, see the correct answers, and know how ready you are before you visit the crewing office. Every question illustration is built into the app, so diagrams, symbols and photos open instantly, even offline on board. PRACTISE YOUR OWN TEST • Choose your department (Engine, Deck or Detailed), then the category and level, just like in the real CES. • Training mode shows the correct answer right after you choose. Exam mode keeps you guessing until the end. • Take 50 or 72 questions, or the whole category. Each new test continues where the last one stopped, so you cover every question. STUDY QUESTIONS WITH ANSWERS • Browse every question by department, category and level with the correct answer shown. • Search inside a category to find a topic fast. SEE HOW READY YOU ARE • A readiness score based on your last five tests, plus your best score and trend. • After each test: correct, wrong and skipped answers at a glance. • Review your mistakes: go through every wrong or skipped question with the correct answer highlighted. REPEAT THE TRICKY ONES • Save difficult questions to Favorites with one tap. • See which ones you missed last time and practise only your favorites. MADE FOR LIFE ON BOARD • Works completely offline. • Short sessions, a clean design and a dark mode that is easy on the eyes during a night watch. • Free, with no ads and no account. If the app helps you, you can buy the creator a beer in Settings. Question bank version 6.0.9.

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.
