Sea Water Interchange by Crenellated Caisson Breakwaters

Suction Caisson Anchors - a Better Option for Deep Water Applications

As offshore exploration and development of oil fields reach water depths of 1,000 to 3,000 m, novel methods of anchoring production platforms become attractive due to cost savings associated with installation. Surface production systems that are viable in these water depths include Tension Leg Platforms (TLP), spar platforms, and laterally moored ship-shaped and semisubmersible vessels. Possibl...

The interaction of surface water waves with submerged breakwaters

Article history: Received 19 October 2007 Received in revised form 19 February 2008 Accepted 20 February 2008 Available online 18 April 2008 This paper concerns the behaviour of nonlinear regular waves interacting with rectangular submerged breakwaters. A new series of experimental results is presented and compared with numerical calculations based upon a Boundary Element Method (BEM) that util...

Disinfection of sea water by ultraviolet radiation.

Warm water occupancy by North Sea cod.

The North Sea has warmed in recent years and there is an ongoing debate into how this is affecting the distribution of fishes and other marine organisms. Of particular interest is the commercially important Atlantic cod (Gadus morhua L.), which has declined sharply in abundance in the North Sea over the past 20 years. Observations of the temperature experienced by 129 individual cod throughout ...

Decomposition of Organic Matter in Sea Water by Bacteria: I. Bacterial Multiplication in Stored Sea Water.

The organic matter in the sea is unevenly distributed between the living plant and animal population, the suspended detritus, the organic matter in the sea bottom, and that present in the water in true and in colloidal solution. The living forms and the detritus make up only a small part of the total organic matter in the sea; the ratio between the organic matter in solution and that present in...
