Western Marine of Seattle Blasts Wrangell Narrows to 24 ft
Western Marine owner Kriss Hart keeps a keen eye on the project. Due to marginal DGPS differential corrections in the Wrangell Narrows area, LBA was forced to put a differential corrections base station up to tighten the XY position of DB BEAVER. The rock drill barge SWINOMISH was finally outfitted with a Trimble 750 RTK 2cm DGPS system by Tony Patrello to assist accurate drilling and blasting. The tidal current in the narrows can reach 5-7 knots at times making the job a challenge. Western Marine is doing the job - no green hands on this project!
