“Marine Pile Repairs by Concrete Encasement” Hawkswood M.G. (2011)

Piled Jetty structures form a vital part of port infrastructure for worldwide trade, yet their life span is often threatened by accelerated corrosion rates affecting steel piles. Many piles suffer from Accelerated Low Water Corrosion (ALWC) with significant section loss well before the design life of the structure expires. Port Owners and Engineers should respond by monitoring steel thickness and providing appropriate protection and repair.

“Foundations to Precast Marine Structures” Hawkswood M.G. & Allsop N.W.H. (2009)

Precast concrete elements are increasingly used in the construction of Maritime Structures. They offer the prospect of efficient unit production and rapid construction, but that requires the efficient construction of adequate foundation restraint. Foundation design and constructability for these elements is therefore a critical area, but little guidance is available on the different forms of foundation available.

“Permeable Woven Fabric Formwork” Cannon E.W. & Boyes R.G.H. (1987)

It was in the early 1960s that the modern development of permeable woven fabric formwork was used to contain concrete both above and especially below the waterline during its placement and curing. Today the principle extends over a complete field of applications under the general name of fabric formwork. One of the leading exponents of this method of construction, E.W Cannon of Proserve Ltd believes that great opportunities for further use of the technique still lay in the future.

“Revetment Construction at Port of Belwan, Indonesia” Loewy E., Burdall A.C. & Prentice A.G. (1984)

This paper describes the revetments used to protect a fine sand reclamation situated in the estuary of the Belawan River in Indonesia. A substantial length of the revetment is situated under a piled quay where grouted mattresses have been used to protect the 1:2.3 sand slope. Significant post construction settlement of the sand slope is expected and special measures were taken to enable the mattresses to accommodate differential settlement. The installation method in difficult environmental conditions and resulting modifications are presented.

“Grout-filled Nylon Bags Speed Alderney Breakwater Repair” Mardel J.C. (1969)

Breakwaters, by their exposed positions, are usually difficult structures to maintain and the Alderney Breakwater in the Channel Islands is no exception. Built netween 1849-1864 to form a harbour of refuge for the British Fleet blockading the French ports, the breakwater arm was built on a submerged rubble mound and extended 4600ft from the shore into the unprecedented depth (for those days) of 36.5m at low water.
