During cargo loading, a high-level alarm activates on a tanker's tank gauging system. What is the CORRECT immediate response?
Answer: Stop cargo transfer immediately and investigate before resuming
A high-level alarm signals the tank is approaching overflow capacity; all transfers must stop immediately to prevent cargo spillage and potential fire or pollution.
A tanker sustains structural damage that causes a dangerous list. After stopping cargo operations, which action improves stability fastest?
Answer: Cross-flooding or ballasting the high side
Transferring ballast to the high side counteracts the list directly and can be accomplished quickly using onboard ballast pumps.
Which document must a tanker master complete and provide to port authorities after a significant pollution incident under MARPOL?
Answer: Oil Record Book entry and incident report to the flag state
MARPOL requires an entry in the Oil Record Book for any discharge and an incident report to the flag state, which may then notify the coastal/port state.
A crew member reports smelling H2S in the deck area near a cargo tank vent. What concentration level of H2S is considered immediately dangerous to life and health (IDLH)?
Answer: 100 ppm
NIOSH/OSHA set the IDLH for H2S at 100 ppm, above which life-threatening effects can occur very rapidly with even brief exposure.
If a tanker's main engine fails in restricted waters and anchoring is not possible, which emergency action should the master take to avoid collision?
Answer: Broadcast SECURITE on VHF Ch 16 to warn nearby traffic and deploy anchor if depth allows
Broadcasting an urgency message warns other vessels of the hazard and deploying the anchor (if depth permits) can arrest the vessel's motion before a collision occurs.
During emergency response to a tanker fire, why should firefighting water run-off be controlled and not allowed to drain freely overboard?
Answer: Run-off contaminated with cargo, foam, or fire products is a MARPOL pollution violation
Firewater contaminated with cargo residues, foam agents, or combustion products constitutes a harmful substance discharge prohibited under MARPOL.
A tanker is required to conduct a pre-arrival emergency drill. Under SOLAS, what is the minimum frequency for abandon-ship drills?
Answer: Once per month
SOLAS Regulation III/19 requires that each crew member participate in at least one abandon-ship drill and one fire drill every month.
