Revised Load Lines Protocol Annex Enters Force January 1

Revisions to the 1988 Load Lines Protocol enter into force on 1 January 2005. Also entering into force on the same date are amendments to the Guidelines on the enhanced programme of inspections during surveys of bulk carriers and oil tankers (resolution A.744(18)). Amendments to the 1988 Load Lines Protocol The amendments adopted in June 2003 to Annex B to the 1988 Load Lines Protocol include a number of important revisions, in particular to regulations concerning: strength and intact stability of ships; definitions; superstructure and bulkheads; doors; position of hatchways, doorways and ventilators; hatchway coamings; hatch covers; machinery space openings; miscellaneous openings in freeboard and superstructure decks; cargo ports and other similar openings; spurling pipes and cable lockers; side scuttles; windows and skylights; calculation of freeing ports; protection of the crew and means of safe passage for crew; calculation of freeboard; sheer; minimum bow height and reserve buoyancy; and others. The amendments, which amount to a comprehensive revision of the technical regulations of the Protocol, will apply to approximately two-thirds of the world's fleet, i.e., to those ships flying the flags of States Party to the 1988 LL Protocol. The amendments do not affect the 1966 LL Convention. June 2003 amendments to the enhanced survey programme for tankers and bulk carriers


Satellite Maps Arctic Ocean Floor

A European satellite launched in 2010 to measure sea-ice thickness in the Arctic is also yielding high-resolution mapping of the ocean floor While the main objective of the polar-orbiting CryoSat is to measure the thickness of polar sea ice and ice sheets that blanket Greenland and Antarctica, its radar altimeter can also measure tiny changes in sea level, 'Terra Daily' is informed by a European Space Agency report.

HydroComp PropCad 2014 released HydroComp PropCad is software for geometric modeling of marine propellers for design and manufacture that provides automatic preparation of 2D design drawings, 3D offsets, thickness classification reports and CAD/CAM data. Used in more than 40 countries for quickly generating propellers and design variants from small outboard production lines to large merchant ship propellers, manufacturers, researchers and designers rely on PropCad for their modeling needs


ClassNK to Research on Brittle Crack Arrest Design

Brittle crack arrest steel on the upper deck and hatch side coaming

  ClassNK announced that it will carry out a joint research project aimed at improving safety standards for ultra-large container ships.   As container ships increase in size, so too does the thickness of the steel that is used. The preventative measures for brittle fracture become even more important with thicker steel especially in areas where higher stress occurs such as the upper deck and hatch side coaming of the cargo holds.

The Swedish company Antiphon AB has introduced a new product for structure borne sound damping; antiphon MPM (metal-polymer-metal) foiled, a sheet metal laminate with a thin foil on one side. The core material is two zinc coated sheet steel laminated with an acoustic inner layer to obtain the best structure borne sound damping. MPM foiled makes it possible to use laminated sandwich systems in more visible environments and also to choose MPM foiled deliberately as a decoration material where


Vessel Tonnage Measurement Interpretation

The U.S. Coast Guard issued a Notice advising of the availability of the revised Tonnage Technical Policy, which has been issued as a cover letter and five enclosures. The Policy is used for interpreting the agency’s vessel tonnage measurement regulations. 70 Fed. Reg. 20924 (HK Law)


EU Policies Improve Air Quality in Harbors

Sulphur dioxide emissions from shipping have sharply decreased in EU ports thanks to an EU policy which limits sulphur content in fuels for ships at berth or at anchor in ports.   Scientists at the European Commission's Joint Research Centre measured key air quality parameters in Mediterranean harbours before and after the entry into force of the low-sulphur requirements in January 2010. In European harbours they found an average decrease of 66% in concentrations of sulphur dioxide

Port of Tallinn signs the purchasing agreement for icebreaker 'MSV Botnica'. The 50 million euro agreement is with the Finnish shipping company Arctia for the outright purchase of the icebreaking vessel. MSV Botnica is a multipurpose icebreaker built in 1998 by Aker Finnyards in Rauma, Finland. Her ice class is ICE-10, length (LOA) is 97.3 and beam 24.3 metres. The maximum speed of MSV Botnica is 16.5 knots in open water; she can maintain a speed of 8 knots in ice up to 80cm thickness


ClassNK Approves New Super-Efficient Fillet Welding Consumable

Noboru Ueda, Chairman and President of ClassNK

  Noboru Ueda, Chairman and President of ClassNK announced that it has granted type approval for the new MX-200F welding consumable, developed by Kobe Steel Co., Ltd. (KOBELCO) to greatly improve welding efficiency and coating quality in commercial vessels.  Up until now, shipbuilders using conventional fillet welding consumables had to make two welding passes for the required weld leg lengths of around 8mm or above
