Recommendations on the Hazard Assessment of Fuel Changeover Processes

OCIMF Guidelines The safe operation of on board installations with marine residual fuel (HFO) and low sulphur marine distillate fuel should be covered by a Hazard Identification (HAZID) assessment.INTERTANKO and OCIMF have developed guidance with Recommendations on the Hazard Assessment of Fuel Changeover Processes with the aim of providing a simple check list of items which should be part of a Risk Assessment and a Hazard Identification (HAZID) assessment, for main engines, auxiliary engines and boiler systems in oil tankers covering the switching to, and long term operation on, low sulphur marine distillate fuel. It is recommended that such assessments are conducted in cooperation with classification societies, equipment manufacturers/ installers and/ or other experienced entities.The differences between the composition and physical properties of low sulphur marine distillate fuel and residual fuels (HFO) result in significant differences with regard to the safe operation of installed systems which should be addressed by specific operational instructions and procedures.Operators will need to undertake a risk assessment of the fuel switching process and, based on the results, consider the initial design or the need for modification to existing equipment, as well as updating instructions and providing associated training to the crew.Classification societies should be consulted ...

Verification of damage stability requirements & mandatory carriage of stability instruments

IMO SLF 55 Outcome The IMO's Sub-committee on Stability and Load Lines and on Fishing Vessels Safety (SLF) at its latest meeting (SLF 55) last week reviewed and finalised the draft Guidelines for the verification of damage stability requirements.The Sub-committee had, at its last meeting in January 2012, also developed draft amendments to mandatory instruments. These amendments to MARPOL Annex I, IBC, BCH, GC and IGC Codes as well as the Guidelines under the Harmonized System of Survey and Certification (HSSC) were also reviewed and finalised at this meeting.The guidelines may be accessed here and amendments here.In addition to the review and finalisation of the Guidelines and the amendments to the instruments, the application of amendments to mandatory instruments was debated (procedures for preparation and approval of tanker damage stability calculations, instructions for operation and demonstration of damage stability compliance - mandatory stability instruments for ships to which MARPOL Annex I, IBC and IGC Codes apply).In this regard, the Sub-committee deliberated on whether compliance for existing ships should be aligned with the intermediate survey or the renewal survey schedule.Led by INTERTANKO, the Sub-committee agreed that the application of the amendments to existing ships should be in line with the first ...

Positive developments on ballast water management

BLG 17 Outcome IMO member states this week agreed on a proposal to undertake a trial period for port state control sampling and analysis once the International Ballast Water Management Convention (BWMC) has entered into force.Acknowledging that there remains a great deal of uncertainty about the methods used to sample ballast water and the real concerns of the industry as expressed in INTERTANKO's paper to the IMO last year, the IMO's Sub-Committee for Bulk Liquids and Gases (BLG 17) has set out a procedure for port states to trial sampling techniques. Importantly, during this trial period port state control (PSC) will refrain from initiating criminal sanctions or detaining the vessel should the sampling show that the discharged ballast water does not meet the standards in the BWMC.The issue was brought about originally at the previous BLG meeting held in early 2012 when concerns were aired by the industry that the methods for sampling and analysis being proposed for use by PSC were actually more stringent than those being used to test the ballast water management systems (BWMS) during Type Approval. In the submission to the IMO's MEPC 64 in October 2012, INTERTANKO and its co-sponsors expanded on the concern explaining ...
