When the seawater pump on an off- shore rig needed replacing, an air hoist supplied by J D Neuhaus, was on hand to provide safe lifting of the compo- nents. The maintenance, repair or re- placement of the associated pumps and pipework in such locations is un- dertaken by Gerritsen On- & Offshore

Services BV, with work recently car- ried out at a rig located in the southern

North Sea. A four man team undertook the dismantling of one pump and pipe- work assembly out of the three simi- lar installations in the pump area. To handle the lifting and temporary stor- age of the components involved, an approximate 20m lift from sea level
