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.

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

  Apache Corporation  today announced an oil discovery at the Phoenix South-1 well - the company's first discovery in Australia's offshore Canning Basin. Wireline and formation pressure tools have confirmed at least four discrete oil columns ranging in thickness between 85 and 151 feet (26 to 46 meters) in the Triassic Lower Keraudren formation, within an overall, sand-rich section between 13,648 and 14,763 feet below sea level (4,160 to 4,500 meters).

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.  


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


IMCI Accredited for Exhaust Emissions Measurement

 The International Marine Certification Institute (IMCI) has become an accredited laboratory for exhaust emissions measurement.   The official announcement was confirmed by the German authority on January 22, 2016.    IMCI is now accredited by District Office of Constance (Germany) as a laboratory for exhaust emission measurement according to Lake Constance Regulation (reflecting Annex G of BSO).   


New Standard for Vessel Underwater Noise

ISO 17208-1:2016, a new international standard for the measurement of underwater noise from ships, has been published by ISO. The full title of this standard is “Underwater acoustics – Quantities and procedures for description and measurement of underwater sound from ships – Part 1: Requirements for precision measurements in deep water used for comparison purposes”. The standard specifies the general measurement system, procedures

JIP Validates DNV GL's Helica Software

The Helica software module in Sesam includes technology that represents industry consensus for cross section analysis of umbilicals and flexible risers, including fatigue analysis of section components such as helix wires and steel tubes. Using Helica, subsea engineers can reduce the analysis time to a fraction, as thousands of simulations may be performed in minutes. Photo DNV GL

A joint industry project run by DNV GL has replicated stresses measured in an umbilical subjected to tension and bending in full-scale tests, further validating the accuracy of the analysis software Helica. DNV GL’s Helica can analyse thousands of simulations in a matter of minutes
