Statistical analysis of owner failure records for 15 steam turbine ships during their first 4 years of operation has - identified categories of serious failure in boiler turbine and automatic control systems; determined failure times and mean time before failure; correlated failure type with cause; examined relationship between failure occurence and service life and conditions.

The experience gained by Lloyd's Register of Shipping's Engineering Research Department in identifying studying and modifying vibration problems in ships hulls and machinery is discussed. Examples include - tuned ballasting; propeller induced hull vibrations; engine balancing; resilient mountings; reciprocating machinery connexions alignments top end bearings; geared turbine noise couplings; propellers and transmission shafting. Design stage vibration assessment also considered.

The basis of protection against fire in passenger ships is as stated in the SOLAS regulations from which evolved the rules of governmental authorities and classification societies. Changes in legislation and in the methods of protection using zonal layouts and modular construction have brought improved standards. This paper restricts itself to questions of fire resistance and retardation rather than the associated subject of extinction.

This publication provides Owners with recommendations on the safety and preservative measures necessary for the maintenance of vessels in a period of lay-up. This guidance notes are intended for general cases and could be modified to adapt to a particular type of ship.

These notes aim to provide guidance to owners intending to re-activate a laid-up ship which was examined at the time of lay-up by Lloyd’s Register Specification Services and for which a lay-up report was issued following a satisfactory examination.

Features of forcibly lubricated hydrostatic bearings and their potential applications in the reduction of shaft contact and valve induced vibration in stern tube assemblies particularly of ships with large diameter or freely rotating propellers discussed. Theoretical and experimental studies compare their characteristics with those of conventional hydrodynamic bearings. Sample calculations illustrate the derivation of specifications for a large tanker stern tube system.

Theoretical studies model tests and full scale trials data are combined to discuss the propulsion and hull resistance of ice-breaking ships - thrust deduction wake fraction rotative efficiency and propulsive efficiency are examined in the towed free-running and icebreaking conditions. Techniques for design prediction of icebreaking resistance and propeller parameters are considered.

These notices contain amendments of the Rules and Regulations for the Classification of Ships, July 2006.

New and existing standards for ships' and offshore cabling are reviewed including NES525526 BS6883 IEC92-35X and 27X series. Their suitability for various applications is examined and the problem of overly rigid safety standards which lead to their improper and inefficient use is discussed. A comparison between onshore and offshore practices is made and new materials and manufacturing processes are mentioned.

The European Chart Hub Operations (ECHO) Project says it has found a way to let ships receive electronic navigation charts (ENC) produced by hydrographic offices around the world as and when they are needed using existing telecommunications systems. Trials are described.

Ship design for noise and vibration reduction is discussed with reference to current acoustic theory design for quiet ships machinery vibration isolation mount/raft characteristics and examples/descriptions from research vessels built for low noise/ vibration

The IACS Unified Requirements for anchoring and mooring are critically discussed in view of increased "ship size" and anchor losses Anchoring systems requirements design dynamic loading kinetic energy also dynamic braking for large ships is described

The finite element method is used to study electrochemical potential distributions around ships hulls to determine the effect of hull surface (paint) condition depth of water open and nozzle type propellers and to assess the effectiveness of zinc anode and impressed current corrosion prevention systems.

Mission profiles for representative large containerships and general purpose frigates are used to discuss the differences between merchant and naval operations. A general purpose model to determine the off-design performance of platform system components is developed and used to compare speed profiles fuel consumptions and emission (COx NOx HC) data for different propulsion concepts in merchant and naval ships.

A comprehensive account of the structural design of OCL's Liverpool Bay class of containerships includes details of - principal particulars profiles deek arrangement construction materials loading structural analyses fatigue whipping. Comparison is made with the previous series of Encounter Bay Ships from which the new class was developed.

US governments policies and regulations on marine pollution are reviewed and the role of the US coastguard in their application and enforcement is examined

Aspects of education and training systems necessary to provide ships officers with skills appropriate to the merchant shipping industry of the future are discussed

The changing nature of the merchant shipping industry is prompted by recession increasing competitiveness and specialised ships Skills and standards required of future officers are discussed

Equations for estimating fore aft and lateral components of wind force and wind induced yawing moments of merchant ships form ship and wind data (without recourse to tunnel tests) are presented. Predictions are compared with reported results on wind resistance of merchant ship models.
