The replacement of the April Hamer is required due to the age of the vessel and the growing cost to maintain her in a seaworthy state. The manner in which she deposits the dredged sand is also a factor that may not be assisting the long term goals of this program,
An important aspect of the LESMP is to determine how efficient the bypass pumps are and what type of Trailer Suction Hopper Dredge (TSHD) is most effective before a decision is made on what is the best replacement for the April Hamer.
It may or may not become evident that dredging could occur in discreet campaigns rather than on a permanent basis, as is currently happening. All these factors and more will be considered before the replacement option can be determined.
It is envisaged that a preliminary design of a replacement vessel only is to be completed under the LESMP. If it is required there will be enough detail to develop a budget so that further funding can be sought. This will occur later in the program toward the beginning of 2010.
