A number of modifications and enhancements of the two primary transfer pump/skimmer units, specifically the GT-185 and GT-260 stocked by the Canadian Coast Guard have been proposed over the past few years. Much of the focus of the testing during this time has centered on dealing with very viscous oils, but the proposed changes will impact the performance of these devices when dealing with any oil.

This paper details the development of a collaborative series of projects supported by Environment Canada and the Canadian Coast Guard over the past six years. It provides background information on the original problems or design limitations of the oil spill recovery equipment. Descriptions of the subsequent modifications are presented, along with performance information which quantifies any improvements to performance. The work has evolved to include partnerships with federal government organizations from Canada and the United States, along with contributions by manufacturers of similar spill response equipment during testing trials.
