it has adverse effects on stability due to free-surface. Fog may be of the summer fog type which forms some distance above the water and may leave a narrow band of clear air just above the water, or winter type, where there mat be dense fog just above the water but clear skies a short distance up. Rain, fog and snow may prevent helicopter operations, which generally require good visibility for landing. Snow may present the additional problem of removal to prevent accumulation. Spray caused by wind and waves can also dump large amounts of water which must be drained, and in colder conditions may freeze and build up a burden of ice. Severe spray may prevent people from working on deck. Atmospheric icing, also known as black ice can occur in sub-Arctic regions, when the air is humid and the temperature is low. Ice forms directly on cold surfaces and can accumulate rapidly, adding topside weight and increasing wind drag. Icing and frozen spray may occur in the same regions and in similar conditions. Lightning is generally not a major problem to steel and concrete structure with adequate lightning protection, but is a hazard to personnel working in high exposed areas.

made before a construction project can be started. There have been developments in sampling of seabeds but some soils remain difficult to analyse and sampling may not produce results as accurate as would be desired. In-place strength may be greater than conventional sampling methods indicate, and sampling methods may not recover and identify critical constituents due to insufficient sampling. Failure to identify potential problems can lead to delays and cost overruns. Many marine structures cover extensive areas, and the soil properties may vary considerably. Cost and time constraints may make it difficult to gather sufficient samples from borings to fully describe the substrate. Other methods for remote substrate analysis may identify potential variations for closer examination.

where only small areas need to be improved. This method increases both bearing and shear resistance and can prevent liquefaction. Injection of cementitious material, following land-based grouting procedures, can be used to displace pore water and give a stronger substrate. The cementing pressures must displace the water yet not cause fracturing of the formation by channelization. Cement particles must be small enough to penetrate the interstices, and a wetting agent can be added to the grout to reduce viscosity.

This type of composite construction appears to have advantages where offshore structures must withstand high local impact forces, such as ice or ship collision, and for the walls of concrete structures where cracks and leakage are unacceptable and difficult or impossible to repair.

River structures include locks, low-level dams, overflow structures, and flood walls. Historically, these have usually been constructed behind sheet pile cofferdams to allow the worksite to be dewatered, so that conventional civil engineering construction methods can be used.

Pile-supported structures consist of steel or concrete piles, driven into soft clays and sands of the seafloor, and usually carry a deck of reinforced concrete. The piles are spaced from 7 to 10 m apart for economy, with a load bearing capacity of 100 to 250 tons each.
