Van Oord - HAM310
We recently finished a refit project involving the replacement of the two main propulsion engines of the HAM310 owed my Van Oord Dredging and Marine Contractors B.V.
Engineering of the renewal Main Engines HAM310
The HAM310 is a trailing suction Hopper dredger built in 1985. Due to the increasing maintenance costs the two original Deutz SBV 12M 540 main engines are to be replaced with two MAK 12M32C engines, this is scheduled to happen in the beginning of December 2010. During this dry docking period the bottom doors in the hopper will also be renewed.
We have been asked by Van Oord to undertake all the engine room aspects of this refit. All the main engine specific systems need to be redesigned and rerouted with a complete drawing pack produced. The vessels auxiliary and harbour generators (both Deutz) are to be replaced with one MAK 6M25C.
In order to achieve the shortest docking period possible, the principle is to have most of the new piping and equipment built on prefabricated skids. To accommodate this requirement we have produced the construction drawings as well as the part/materials lists and the isometric drawings.
Before the engineering production stage, and as basis for the 3d-modelling, the engine room is measured by means of a laser scan. This produces what is known as a “point cloud scan” which can be read by our in house 3d piping software. The big advantage of this is that we now have a digital image of the existing piping, and we can resolve most of the conflicts without going onboard to investigate each every single detail.
