Due to change in procedure for completing Supplement As already advised in ClassNK Technical Information No. TEC-0771 dated 13 May 2009, in accordance with Reg. 14 of MARPOL Annex VI, the sulphur content limit value for a fuel oil used outside of an Emission Control Area will be changed from 4.50% m/m to 3.50% m/m on 1 January 2012 and will be effective thereafter.Required sulphur content limit values are described in section 2.3 of the Supplement to the IAPP Certificate using a check box form. So far, only the check box for the sulphur content limit value which is applicable at the time of issuance of the Certificate has been ticked off. Therefore, whenever a new sulphur content limit values is enforced, the IAPP Certificate needs to be replaced each time.However, the IMO MEPC 61 agreed that section 2.3 of the Supplement should be completed on the basis of all available options, with a view to avoiding the need for repeated re-issuance of the Supplement, as the various given dates are passed. In accordance with this agreement, ClassNK will change the procedure for completion of section 2.3 of the Supplement and tick off all the check boxes which may be ...

Offshore Technology Conference Severn Trent De Nora, a leading provider of electrolytic seawater disinfection systems, will showcase its line of water and wastewater treatment systems at theOffshore Technology Conference to be held May 2-5, 2011, at Reliant Park in Houston, Texas.The following products will be featured during the conference: The OMNIPURETM Series 55 marine sewage treatment system utilizes a unique electrolytic treatment process combined with electrocoagulation to provide safe and effective treatment of black and gray water.The certified treatment process provides wastewater effluent quality well below MEPC.159(55) requirements while eliminating the need to handle waste solids from raw, untreated influent.Along with a unique solids management system that removes concentrated solids automatically, in situ, the light-weight systems feature a small footprint and are easy to install and maintain. With an individual unit capacity ranging up to 17,280 gal/day (65 m3/day), OMNIPURE 55 systems can be combined for increased capacity.The systems have Bureau Veritas certification and USCG certification to IMO Resolution MEPC.159(55). A scale model of the OMNIPURE Series 55 will be at the booth for technology demonstrations.The SANILEC?electrochlorination system generates hypochlorite from seawater and has demonstrated reliable, economic and low-maintenance operation in installations throughout the world.When injected into the cooling water ...

Wider Caribbean Region Special Area The United States Coast Guard (USCG) announces the date for the entry into effect of discharge requirements from ships in the Wider Caribbean Region (WCR) special area (SA) as specified in the International Convention for the Prevention of Pollution from Ships (MARPOL) Annex V, Regulation 5 and Coast Guard regulations. MARPOL Annex V and the US regulations apply to vessel and reception facility activities in the WCR region.The date of entry for discharge requirements in the WCR SA as 1 May 2011 was adopted via IMO Resolution MEPC.191(60).The discharge restrictions are contained in 33 CFR 151.71 which reads in full as follows:(a) When a ship is located in a special area referenced in 151.53 of this part, no person may discharge garbage from the ship, except as allowed in paragraph (b) or (c) in this section.(b)Except as provided in paragraph (c) of this section, disposal into the sea of victual waste must be made as far as practicable from land but, in any case, not less than 12 nautical miles from the nearest land.(c)Disposal into the Wider Caribbean region of victual wastes which have been passed through a comminuter or grinder shall be made as ...

Concept to minimise the amount of oily bilge water in machinery spaces The Integrated Bilge Water Treatment System (IBTS) concept was promoted by Japan and recognised by the IMOthrough its MEPC.1/Circ 642 as an excellent concept to minimise the amount of oily bilge water generated in machinery spaces and with an integrated means to process the oily bilge water and oil residue (sludge).In principle, the IBTS is a concept of an installation containing a bilge primary tank and proper control of the flow of drain streams, aiming to segregate as much as possible oily streams from the drain streams of clean water, and avoid their admixture.Unfortunately, ships which use oily water separator systems based on the IBTS concept have reported negative experiences with port state control officers who are not convinced that ships can generate significantly low oily water volumes.To avoid this, Japan and the International Association of Classification Societies (IACS) have suggested that ships equipped withinstallations based on the IBTS concept are given a Statement of Fact, which is a check list acknowledging that the installation follows the IBTS as described in MEPC .1/Circ. 642.INTERTANKO and other ship owner organisations supported the promotion of IBTS. INTERTANKO recommended that Governments ...
