7.5 Vapour Emission Control (VEC) Systems
---ใช้เพื่อการศึกษาเท่านั้น---
Shipboard Vapour Emission Control (VEC) systems tend to fall into two main
categories:
งานห้องสมุด ศูนย์ฝกพาณิชย์นาวี
Those systems conforming to IMO guidelines that provide a system for returning
cargo vapours to the shore for reclamation or incineration of the petroleum vapour.
(See Section 11.1.13.)

Proprietary systems for recovering petroleum liquid or vapour from the vapour that
would otherwise be vented during the loading operation or during the loaded
passage.

Operators of VEC systems should be trained in the use of the system fitted to their
ship.

7.6 Stern Loading and Discharging Arrangements

The use of a stern manifold for cargo transfer operations introduces additional hazards
and operational concerns. Procedures should address the following:

The requirement to monitor simultaneously the stern manifold and the cargo tank
deck area.
ึ
Additional trip hazards from working in a mooring area.
Spill containment arrangements on the aft deck area.
Provision of drip trays beneath the stern manifold.
Elimination of potential sources of ignition from accommodation openings and
electrical fittings.
Connection and disconnection of hoses where no lifting gear is available.
