An experimental study has been conducted to evaluate the conventional method of estimating the upright and heeled wind heeling moment on multihull vessels. Static wind tunnel tests were conducted on various hull forms and geometric bodies as well as dynamic gust tests on four multihulls. Revised formulae were derived and have been submitted to the IMO for consideration during the revision of the HSC Code.

A description is given of the measurement of negative skin friction forces on the model piles driven in the cylindrical chamber filled with remolded marine clay. After some introductory information a look is taken at the test apparatus. Next test preparation and procedures are outlined. This is followed by consideration of the test results and pullout test results.

Effect of seaquakes on a floating body in an open sea and in an enclosed basin was studied theoretically and experimentally. First sea bottom and breakwaters were replaced by the distributions of highly pulsating bubbles and then formulas for surge sway and heave accelerations of the floating body were derived in term of the acceleration of sea bottom or breakwaters. The theoretically predicted responses of the floating body were well supported by laboratory experiments.

The purpose of this paper is to assist Surveyors in the interpretation and implementation of the IMO Guidelines with respect to LR's work. The use of plastic pipes in shore based installations is well established but the application to ships has been limited by safety aspects. These guidelines have opened the door to wider use of plastic pipes on ships.

An OBS (on-board measurement system) is presented that tests automotive emissions. The OBS uses a ZrO2 type NOx-O2 sensor as one of its main components. Test results of this system obtained from on-road measurements using a diesel vehicle are described as well as the configuration of the system. In addition the possibility and effectiveness of the ZrO2-type sensor for marine application is discussed based on continuous monitoring results on actual ships.

The principles methods and programs of oil monitoring are discussed. Old techniques of marine machinery maintenance are reviewed. From the monitored experiences of diesel engines mounted in tugboats a suitable maintenance system is suggested based on oil monitoring. Applications are carried out. It is concluded that oil monitoring methods applied to ship machinery monitoring are helpful in reforming the old maintenance techniques and developing predictive maintenance in ships.

Deformation of rubble mound breakwater wave force on a rubble stone and run-up height were measured in experiments to obtain fundamental data for establishing a design method. The process of breakwater profile change resulting from the movement of rubble stone by waves was studied. Characteristics of profile change response of rubble stone to waves and change in the hydraulic function of rubble mound breakwater with development of profile change were investigated.

When ice sheets adfreeze to structures with a circular cross-section vertical ice loads act on them as the water level changes due to tides. At a certain water level the ice sheets fracture. Modes of failure are classified as bending failure and adfreeze bond failure. Theoretical equations have been developed to estimate vertical ice loads which correspond to each mode of failure. Equations were verified by field experiments.

Papers on design theory in general and on the practical design of ships are compared in an attempt to trace the influence of design theory on ship design. About 30 papers and books published between 1951 and 1995 are reviewed. The influence of design theory seems to be limited to the application of computer programmes introduction of economic measures of merit and designing of design tasks. It is suggested that literature on design theory should reach the design engineers more effectively.

Experiments were conducted on micro-bubble drag reduction (MBDR) by injecting compressed nitrogen from a cross-stream slot into the wall turbulent boundary layer (TBL) of a high speed water tunnel. Nitrogen was injected at volumetric flow-rates from 30 to 180 standard litres per second with the tunnel operating at a free-stream velocity of 11m/s. In this paper preliminary experimental results focusing on the influence of bubble size on the effectiveness of MBDR are presented. The results in this study suggest that density modification is the primary mechanism for MBDR. The influence of bubble size on the efficiency of MBDR is very small.

This paper describes the first development of sophisticated pressure measurement techniques for a full scale propeller and its success. Excellent agreements with theory were found at most of the measurement points especially at the fore part of the blades. The present measurement has provided a number of invaluable standard data to validate the numerical computational techniques on marine propellers at high Reynolds number.

In this paper an experimental system to measure contact ice loads on a podded propeller in different operating conditions is described. The system is capable of measuring loads on different parts of the system in different ice thicknesses and azimuthing angles. There is a lack of information as to the loads occurring on podded propeller systems operating in ice. Hence this study aims to close the knowledge gap for this type of propulsion system. This paper describes the experimental setup designed and built at the National Research Council of Canada Institute for Marine Dynamics (NRC-IMD) for measuring ice loads on such a system.
