Profile: Ray Offshore & Marine Supply specializes in offering equipment & services to offshore/onshore oil & gas exploration and civil foundation & construction companies. Our product line includes pile hammers, piling rigs, compressors and heat exchangers. Our pile hammers include diesel pile hammers and hydraulic pile hammers. Our diesel pile hammer is a single-acting hammer which is used for driving heavy piles into hard or dense soil. The heavy piston which is striking at low velocity allows more energy to be transferred into the motion of the pile, thereby reducing impact and damage to the butt or head of the pile.
