Engine Room Access Control

Engine room access control restricts entry to machinery spaces to authorized personnel, protecting propulsion, steering, and power generation from sabotage or seizure. ISPS Code Part A Section 9.4.2 requires the ship security plan to prevent unauthorized access to restricted areas; Part B paragraph 9.18 lists machinery spaces of category A and the steering gear among spaces a ship may designate restricted. Measures tighten by security level: identification checks at MARSEC level 1, escorted or limited access at level 2, and access suspended or guarded at level 3.
