Tanker Familiarization Emergency Procedures 5

Question 1

During cargo loading, a high-level alarm activates on a tanker's tank gauging system. What is the CORRECT immediate response?

Accepted Answer

Stop cargo transfer immediately and investigate before resuming

Answer

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.

Question 2

A tanker sustains structural damage that causes a dangerous list. After stopping cargo operations, which action improves stability fastest?

Accepted Answer

Cross-flooding or ballasting the high side

Answer

Transferring ballast to the high side counteracts the list directly and can be accomplished quickly using onboard ballast pumps.

Question 3

Which document must a tanker master complete and provide to port authorities after a significant pollution incident under MARPOL?

Accepted Answer

Oil Record Book entry and incident report to the flag state

Answer

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.

Question 4

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)?

Accepted Answer

100 ppm

Answer

NIOSH/OSHA set the IDLH for H2S at 100 ppm, above which life-threatening effects can occur very rapidly with even brief exposure.

Question 5

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?

Accepted Answer

Broadcast SECURITE on VHF Ch 16 to warn nearby traffic and deploy anchor if depth allows

Answer

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.
