DNV—GL — COMPETENCE RELATED TO THE USE OF REMOTELY SENSED EARTH OBSERVATION DATA ON BOARD VESSELS

The present DNV GL standard was developed with the intention to establish a proper foundation and common ground for both the development of competence of individuals and for training programs relating to the use of earth observation data and products.

It could be used by organizations to define their expectations towards training providers, by training developers and providers as the backbone of a learning program, by companies to verify the competence of their people and define their training needs, and by verifiers as a reference document for independent evaluation of training programs. Of course, the specific details relating to the ship-specific arrangements and systems can't be captures in a general standard. The constantly increasing ice of earth observation data on board ships is providing so many new opportunities and can definitely supply sailors with so much of valuable information.

Today, the current use of such data in ice information and meteorology forms one of the parts of number of useful services, which is also increasing. Officers on board merchant and navy ships are becoming more and more familiar with earth observation data and, of course, it is very important that their competency allows them to properly analyze the quality of the provided data.

LR CODE ON NOISE LEVELS ON BOARD SHIPS (2014) AND GUIDANCE FOR SHIPOWNERS ON CONDUCTING NOISE SURVEYS

Here is the publication which was prepared by LR professional and officially by Lloyd's Register marine department; the team of authors combined the Code on Noise Levels on Board Ships in order to provide the owners of the vessels with the required technical guidance to follow during the noise surveys.

The Code itself, apart from the general information, contains the requirements to the measuring equipment and process of measurement, applicable noise exposure limits, insulation issues, hearing protection and warning information, reporting format, inclusion of noise issues in SMS, methods of attenuating noise, and simplified procedure for determining the exposure to noise.

The Guidance, in turn, provides readers with a quick review of the new for new noise legislation, assessment condition, noise assessment procedures, maximum levels of noise, insulation and reporting, all supplemented with a number of tables and figures. In fact, the number of publication addressing the noise level measurements, associated procedures and regulation, is not that huge so we would recommend this booklet to anyone involved in this process as well as to the owners, crew members, class and PSC inspectors.

LR CODE FOR LIFTING APPLIANCES IN A MARINE ENVIRONMENT

Nowadays, almost all of the national maritime authorities require that the lifting appliances installed on board ships must be approved, examined, tested and subsequently certified by the person or organization considered competent, prior to putting them into actual service.

The certification provided by Lloyd's Register classification society is internationally recognized and worldwide accepted and respected. As a result, Lloyd's Register may undertake all necessary certification as well as subsequent periodical inspections in order to ensure compliance of the shipboard lifting appliances with applicable requirements of all relevant statutory instruments. Ships and/or offshore installations having the lifting appliances that have been constructed and tested in compliance with the structural as well as machinery requirements listed in the present LR Code, may be assigned the Special Features classification notations by LR.

This document shall apply to all marine and offshore lifting appliances, including cranes, derrick crane systems, ramps and lifts, launch and recovery systems, etc. It shall also apply to ship lift and transfer system installations used to raise and lower the ships using their winches/jacks.  The appliances that have not been mentioned above should be treated on the general basis of the present document.

DNV—GL — CERTIFICATION OF TIDAL AND WAVE ENERGY CONVERTERS

The DNV OSS is intended to present procedures and principles for the certification of tidal and wave energy converters conducted by DNV classification society. Such converters, when installed either inshore or offshore, will obviously face same environmental challenges as the converters installed on the offshore oil and gas installations. This class society will use its experience from the offshore industry to develop necessary guidance for the renewable energy installations.

That is why the reference is given to the DNV offshore standards/recommended practices and international standards. The document covers all concepts of tidal and wave energy converters and refers primarily to the near-shore and offshore concepts for such converters; however, it may also be applied to the shoreline devices. Generally, converters may be of floating or fixed types and they are usually constructed of steel, concrete or composite material.

This OSS is flexible enough to match the differences in technology and new concepts that are currently being developed, and provides a framework for proper application of the certification to the marine renewable energy. The publication contains definitions and references, safety philosophy, certification deliverables, explains the basic principles of certification as well as qualification of new technology, procedures to be followed for assignment of certification, verification of procured items, documentation and many other issues.

DNV—GL — CERTIFICATION OF FIRE PROTECTION SYSTEMS FOR WIND TURBINES

We may all observe the steady and rapid growth of the wind energy industry during the recent years. This relates not only the total number of constructed and installed wind turbines but also to the individual rating and level of sophistication of the wind turbine technology.

The expansion to offshore regions will definitely further drive the development of this technology and increase the investment level. Taking this background into consideration, the demand for reliable and effective protection of the systems and also the investments have significantly grown. It goes without saying that the effective and reliable fire protection system substantially contributes in the risk reduction. Reliable and effective operation of the FPS (fire protection systems), considering both active/passive measures, facilitate the reduction of the risk of bodily injury as well as of damage to the property that may be caused by fires in wind turbines. These systems may even be capable of preventing the total loss of turbine.

This service specification by DNV GL class society is aimed to define and ensure a high quality model for both design and construction of modern fire protection systems. This document will be subjected to frequent revisions in accordance with experiences, new findings in the area and all future technological developments. The authors are intending to set up a common technical basis of understanding for makers of fire protection components and complete FPS with regard to high quality, reliability and operational effectiveness of the products.

DNV—GL — CLASSIFICATION BASED ON PERFORMANCE CRITERIA DETERMINED FROM RISK ASSESSMENT METHODOLOGY

The present document presents the service specification released by DNV Class Society for classification of offshore installations on the basis of the various risk assessment techniques. This would mean that the acceptability of design as well as of the extent of verification are basing on rthe isk assessment rather than reliance upon the prescriptive rules.

The primary objective of such approach is to provide an alternative route for classification of individual and/or novel designs whilst trying to maintain an acceptable level of safety and integrity that could ve considered equivalent to that achieved under more traditional class societies' rules. Though not mentioned specifically through the present document, avoidance of adverse environmental consequences must be taken into account as necessary, to the extent covered by traditional class rules. The requirements provided in this publication shall apply to the fixed offshore installations, including floating ones designed for use at a fixed location.

The service is alternative or complementary to classification based on other DNV service specifications (DNV-OSS series) for such installations. Where classification based on risk assessment is applied only to a part of an installation, the remainder of the installation shall meet the requirements of other applicable DNV rules. In such cases, it is critically important to ensure a safe interface between the two classification methods i.e. that design based on risk assessment does not have a negative effect upon safety or integrity under classification rules and vice versa...
