Guidance on Cargo Compressor Room Entry On Board Gas Carriers (Risk based)

Author: INTERTANKO ISTEC
Genre: Reference book
Format: PDF
Quality: Scanned pages + text layer
Pages count: 8
Description: Recognising the safety benefits of the existing mandatory requirements for ventilation, openings for entry and exits, and gas detection system applicable to compressor rooms design and features, this document provides advice on the safety measures to be put in place when entering cargo compressor rooms that have been risk assessed for entry without the need for an Enclosed Space Entry Permit, in the framework of a special entry procedure.
This risk-based procedure will help align best practice amongst gas vessel operators for compressor room entry and is also aiming to become a reference for IMO works related to enclosed space entry.
The risk assessment outcome is at the heart of this guidance, as such some compressor rooms may not be entitled to the special entry procedure.
Additional info: The requirement for routine access to cargo compressor rooms on board has meant that the daily issuance of
an Enclosed Space Entry Permit to this space could increase paperwork and also dilute the safety culture of
the crew on board.
This Guidance proposes a risk-based method to control compressor room entry without lowering safety
standards.

Introduction and scope
International Maritime Organization (IMO) Resolution A. 1050 (27) defines an 'enclosed space' as a space that
has any of the following characteristics:
.1 limited openings for entry and exit;
2. inadequate ventilation; and
3 is not designed for continuous worker occupancy.
Furthermore, the resolution includes cargo compressor rooms, along with pump rooms, in its non-exhaustive
list of examples of enclosed spaces. Therefore, a cargo compressor room requires an Enclosed Space Entry
Permit
The International Code of the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC
Code) specifies the requirement for a cargo compressor room's ventilation, openings for entry and exits, and
gas detection system. These IGC requirements may allow some cargo compressor rooms to be dealt with as
"enclosed spaces with special entry procedure" - as they have permanent and appropriate fixed mitigations
in place.
To recall, INTERTANKO, having sponsored an IMO paper which aims to review the current resolution A. 1050
(27). on revised recommendations for entering enclosed spaces aboard ships regarding its application to, gas
carriers, especially to compressor rooms, suggested a tailor-made procedure be adopted 5s standard best
practise to help align best practise amongst gas vessel operators. As such, this INTERTANKO Guidance provides
advice on the safety measures to be put in place when entering cargo compressor rooms that have been
risk assessed for entry without the need for an Enclosed Space Entry Permit, in other words, deemed as
"enclosed spaces with special entry procedure". The scope of the document is limited to guidance on the
cargo compressor room entry procedure.
This INTERTANKO Guidance will be reviewed and updated once the IMO's work on enclosed spaces
related to IMO Resolution A. 1050 (27) has been completed and circulated to IMO Member States.
